In various low-voltage, high-efficiency application scenarios such as power management systems, battery protection circuits, motor drives, portable devices, and DC-DC converters, ROHM's RW4E045ATTCL1, with its advanced P-channel MOSFET design, low on-resistance, and compact footprint, has been a preferred choice for engineers worldwide during design selection. However, in the context of persistent global supply chain uncertainties and trade tensions, this imported component increasingly reveals critical pain points: extended lead times (often spanning months), procurement costs vulnerable to currency fluctuations, and delayed technical support. These challenges severely impact production schedules and cost optimization for downstream enterprises. Consequently, domestic substitution has evolved from an "alternative" to an "imperative," serving as a vital strategy for ensuring supply chain resilience, reducing expenses, and enhancing core competitiveness.
Leveraging years of expertise in power semiconductors, VBsemi introduces the VBQG2317 P-channel MOSFET through independent R&D. This product is precisely aligned with the RW4E045ATTCL1, offering core advantages of parameter enhancements, technological parity, and full package compatibility. It serves as a direct drop-in replacement without circuit modifications, delivering a more stable, cost-effective, and locally supported high-quality solution for diverse low-voltage electronic systems.
Comprehensive Parameter Surpassing, Ample Performance Margin, Adapting to Demanding Conditions.
Tailored as a domestic alternative to the RW4E045ATTCL1, the VBQG2317 achieves significant, leapfrog improvements in key electrical parameters, providing robust performance guarantees for low-voltage applications:
First, the drain-source voltage is maintained at -30V (absolute value 30V), matching the original model's 30V rating while ensuring reliable operation in environments with voltage variations and transients.
Second, the continuous drain current is increased to -10A (absolute value 10A), substantially surpassing the original model's 4.5A—a 122% enhancement in current-carrying capacity. This enables support for higher-power designs and improves system stability, whether upgrading equipment or optimizing existing circuits.
Third, the on-state resistance is as low as 17mΩ (@10V gate drive), significantly better than the RW4E045ATTCL1's 48mΩ. This reduction minimizes conduction losses, directly boosting overall efficiency and reducing heat generation, thereby easing thermal management demands and lowering energy costs.
Additionally, the VBQG2317 supports a ±20V gate-source voltage, offering strong gate ESD and noise immunity, preventing false triggering in complex electromagnetic environments. The -1.7V gate threshold voltage balances drive convenience and switching reliability, seamlessly compatible with mainstream driver ICs without circuit adjustments, further simplifying substitution.
Enhanced with Advanced Trench Technology, Reliability and Stability Inherited and Upgraded.
The core strength of the RW4E045ATTCL1 lies in its low on-resistance and efficient switching performance. The VBQG2317 employs industry-leading Trench gate technology, building upon the original model's advantages while optimizing device reliability across multiple dimensions. The device undergoes rigorous pre-shipment testing, including 100% avalanche and high-voltage screening, demonstrating excellent single-pulse avalanche energy handling. It effectively manages energy surges during switching, reducing the risk of avalanche breakdown. Through optimized intrinsic capacitance design, it lowers charge/discharge losses during switching and enhances dv/dt tolerance, perfectly matching the RW4E045ATTCL1's application scenarios. Even under harsh conditions like high-frequency switching and rapid transients, it maintains stable operation, enabling direct replacement without topology changes. Moreover, the VBQG2317 features an extensive operating temperature range of -55°C to 150°C, adapting to diverse environments such as industrial settings and outdoor extremes. Having passed long-term reliability verifications, including high-temperature/high-humidity aging tests, its failure rate is well below industry averages, ensuring durable performance for critical applications like consumer electronics, automotive systems, and backup power supplies.
Fully Compatible Package, Enabling "Virtually Cost-Free, Risk-Free, and Immediate" Replacement.
For downstream enterprises, a primary concern in domestic substitution is the R&D investment and time required. The VBQG2317 addresses this seamlessly through its package design. The device uses a DFN6(2x2) package, fully identical to the RW4E045ATTCL1 in pinout, pin spacing, dimensions, and thermal pad structure. Engineers need not modify PCB layouts or thermal designs, achieving "plug-and-play" replacement. This high compatibility reduces verification time significantly—sample validation typically completes within 1-2 days—while avoiding costs from PCB revisions or mold adjustments. It also preserves original product certifications and外观, accelerating supply chain cycles and enabling swift import substitution to capture market opportunities.
