In applications requiring compact dual-channel power switching—such as portable devices, battery management systems, load switches, and motor drive modules—RENESAS IDT's UPA1890GR-9JG-E1-A, with its integrated N+P channel configuration and balanced performance, has been a popular choice for space-constrained designs. However, in the current climate of global semiconductor supply volatility, extended lead times, and rising procurement complexities, dependence on imported components like this poses significant risks to production continuity and cost predictability. The urgent need for a reliable, high-performance domestic alternative has become a strategic priority for enterprises aiming to secure their supply chains and enhance product competitiveness.
Leveraging its extensive expertise in power semiconductor design, VBsemi introduces the VBA5325—a dual N+P channel MOSFET engineered as a direct, pin-to-pin replacement for the UPA1890GR-9JG-E1-A. With superior electrical parameters, advanced trench technology, and full package compatibility, the VBA5325 offers a seamless, drop-in solution that eliminates redesign efforts while delivering upgraded performance and assured supply.
Performance Superiority: Higher Current, Lower Loss, and Robust Operation
Tailored to match and exceed the UPA1890GR-9JG-E1-A, the VBA5325 achieves notable enhancements across key specifications, providing greater design margin and improved efficiency:
- Drain-Source Voltage (VDS): Rated at ±30V, fully compatible with the original’s 30V rating, ensuring reliable operation in standard low-voltage applications.
- Continuous Drain Current (ID): Increased to ±8A, a 33% improvement over the original’s 6A. This higher current capability supports more demanding loads and enhances system robustness.
- On-Resistance (RDS(on)): As low as 18mΩ (N-channel) and 40mΩ (P-channel) at VGS=10V, significantly lower than the original’s 64mΩ (at VGS=4.0V). This reduction minimizes conduction losses, improves thermal performance, and boosts overall efficiency.
- Gate-Source Voltage (VGS): Supports ±20V, offering stronger gate robustness and better noise immunity in electrically noisy environments.
- Gate Threshold Voltage (Vth): Optimized at 1.6V~1.7V, ensuring easy drive compatibility with common logic-level controllers and driver ICs without circuit modification.
Advanced Trench Technology for Enhanced Reliability and Switching Performance
While the UPA1890GR-9JG-E1-A provides reliable performance, the VBA5325 employs advanced Trench MOSFET technology to achieve lower on-resistance, reduced gate charge, and improved switching characteristics. This technology enables faster switching speeds, lower dynamic losses, and better thermal stability. The device is designed to operate across an extended temperature range and undergoes rigorous reliability testing, including high-temperature and high-humidity aging, ensuring long-term stability in demanding applications such as consumer electronics, automotive subsystems, and industrial controls.
Full Package and Pin-to-Pin Compatibility for Effortless Replacement
The VBA5325 is housed in a standard SOP8 package, which is mechanically and electrically identical to the UPA1890GR-9JG-E1-A. Pinout, footprint, and thermal characteristics are fully compatible, allowing engineers to replace the existing component without any PCB layout changes or thermal redesign. This plug-and-play approach dramatically reduces substitution time, eliminates re-validation costs, and accelerates time-to-market for upgraded or new designs.
Local Supply Chain and Technical Support: Stability and Responsiveness
Unlike imported alternatives subject to uncertain lead times and logistical delays, VBsemi’s domestic manufacturing and streamlined logistics ensure stable supply and shorter lead times—typically within 2–3 weeks, with expedited options available. Additionally, VBsemi provides dedicated local technical support, including comprehensive datasheets, application notes, substitution guidance, and prompt design-in assistance. This responsive support framework resolves common pain points associated with overseas suppliers, such as slow feedback and communication barriers.
From portable electronics and power distribution modules to battery-powered systems and compact motor drives, the VBA5325 stands out as a superior domestic alternative to the RENESAS IDT UPA1890GR-9JG-E1-A. With its enhanced performance, drop-in compatibility, reliable technology, and secure local supply, the VBA5325 enables companies to reduce dependency on imported components, lower system costs, and strengthen supply chain resilience—all without compromising quality or design effort.
