In compact, low-voltage power management circuits such as portable devices, battery protection modules, load switches, power path management, and low-power DC-DC converters, ROHM's RTF010P02TL P-channel MOSFET, with its small SC70-3 package and tailored performance for space-constrained designs, has been a common selection for engineers. However, in the current landscape of global component shortages and extended lead times, this imported part presents challenges including limited availability, cost volatility, and slower technical support. This situation drives an urgent need for a reliable, high-performance domestic alternative to secure supply chains and optimize costs.
Responding to this market demand, VBsemi introduces the VBK2298 P-channel MOSFET, developed through independent R&D. This product serves as a direct, pin-to-pin replacement for the RTF010P02TL, offering significant parametric advantages, full package compatibility, and enhanced performance, enabling a seamless upgrade without circuit modifications.
Significant Parameter Advancements for Higher Performance and Robustness
Designed as a superior domestic replacement for the RTF010P02TL, the VBK2298 delivers substantial improvements in key electrical specifications:
- Drain-Source Voltage (Vdss): Maintains -20V, fully matching the original part's voltage rating for consistent application in 12V/5V systems.
- Continuous Drain Current (Id): Rated at -3.1A, a remarkable 210% increase over the original 1A rating. This provides ample current headroom, reduces thermal stress, and enhances system reliability in demanding loads.
- On-Resistance (RDS(on)): Achieves an ultra-low 100mΩ (at both Vgs=2.5V and 4.5V), which is 74% lower than the RTF010P02TL's 390mΩ (at Vgs=4.5V). This drastic reduction minimizes conduction losses, improves power efficiency, and allows for cooler operation or more compact thermal design.
- Gate Threshold Voltage (Vth): Features a standard -0.6V threshold, ensuring easy drive compatibility with common logic-level controllers and MCUs.
- Gate-Source Voltage (Vgs): Rated at ±12V, offering robust gate oxide protection and noise immunity in dynamic environments.
Advanced Trench Technology for Enhanced Efficiency and Reliability
The VBK2298 utilizes advanced Trench MOSFET technology, which is the foundation for its exceptionally low on-resistance and high cell density. This technology enables superior switching performance and lower gate charge compared to planar counterparts, contributing to reduced switching losses in high-frequency applications. The device is designed and tested for high reliability, making it suitable for consumer electronics, IoT devices, and other applications requiring long-term stable operation.
Seamless Drop-In Replacement with SC70-3 Package
The VBK2298 is offered in the standard SC70-3 surface-mount package, which is identical in footprint, pinout, and dimensions to the RTF010P02TL. This complete package compatibility allows for a true "drop-in" replacement on existing PCB layouts. Engineers can validate the substitution quickly, avoiding time-consuming redesigns, layout changes, or requalification efforts, thereby accelerating time-to-market for product updates.
Local Supply Chain Assurance and Responsive Support
VBsemi provides a stable and controllable local supply chain for the VBK2298, mitigating risks associated with international logistics and allocation. With streamlined production and localized inventory, lead times are significantly shorter and more predictable than for imported alternatives. Furthermore, VBsemi's technical support team offers prompt, direct assistance for substitution validation, application troubleshooting, and optimization, ensuring a smooth and risk-free transition from the RTF010P02TL.
From battery-powered devices and portable gadgets to various low-voltage switching and power management circuits, the VBK2298 stands out as the ideal domestic alternative to the ROHM RTF010P02TL. It combines higher current capability, significantly lower on-resistance, perfect package compatibility, and secured local supply into one solution. Choosing the VBK2298 is not just a component swap—it's a strategic upgrade toward better performance, improved supply chain resilience, and greater cost-effectiveness for your designs.
