In modern compact power designs such as synchronous buck converters, motor drive circuits, load switches, and battery management systems, the demand for integrated dual N+P channel MOSFETs in SOP8 packages is rapidly growing. ROHM's SH8M24TB1 has been a popular choice for its space-saving configuration. However, in the current climate of global component shortages and extended lead times, reliance on such imported parts introduces significant risks to production continuity and cost predictability. The urgent need for a reliable, high-performance domestic alternative has never been greater. Responding to this critical industry demand, VBsemi introduces the VBA5415, a Dual N+P channel MOSFET engineered to directly replace the SH8M24TB1. It offers superior electrical characteristics, full package compatibility, and the assured supply chain of a local manufacturer, presenting a risk-free upgrade path for your designs.
Superior Parameters for Robust Design and Higher Efficiency
Tailored as a direct replacement for the SH8M24TB1, the VBA5415 delivers significant enhancements across all key specifications, providing greater design margin and improved end-product performance:
Balanced & Higher Voltage Rating: The VBA5415 offers a symmetrical ±40V drain-source voltage rating for both channels. This provides a robust foundation for 24V system applications, ensuring reliable operation against voltage spikes and transients, matching the common application territory of the SH8M24TB1 (45V) with ample safety margin.
Drastically Increased Current Capability: The continuous drain current is dramatically upgraded to +9A (N-channel) and -8A (P-channel), more than doubling the current handling capacity compared to the SH8M24TB1's +4.5A/-3.5A. This allows for supporting higher load currents, enabling power density improvements or providing significant headroom for enhanced reliability in existing designs.
Remarkably Lower Conduction Losses: The VBA5415 features an exceptionally low on-state resistance of just 15mΩ (N-channel) and 17mΩ (P-channel) at Vgs=10V. This represents a reduction of over 60% compared to the SH8M24TB1's 46mΩ. The drastically reduced RDS(on) minimizes conduction losses, directly boosting system efficiency, reducing thermal stress, and simplifying heatsinking requirements.
Optimized Gate Drive: With a gate-source voltage rating of ±20V and a well-defined threshold voltage (Vth) of ~1.8V/-1.7V, the VBA5415 ensures strong noise immunity and easy drive compatibility with standard PWM controllers, facilitating a straightforward replacement without gate drive circuit modifications.
Advanced Trench Technology for Proven Reliability
The VBA5415 is built using VBsemi's advanced Trench MOSFET technology. This process achieves the optimal balance between low on-resistance, fast switching speed, and high reliability. The device undergoes rigorous quality control and reliability testing, including HTGB (High Temperature Gate Bias) and HTRB (High Temperature Reverse Bias) tests, ensuring stable long-term operation even in demanding environments. The symmetrical and low Vth characteristics contribute to cleaner switching and improved control in synchronous applications.
Pin-to-Pin Compatible SOP8 Package for Immediate Replacement
The VBA5415 is housed in a standard SOP8 package that is pin-for-pin compatible with the ROHM SH8M24TB1. This complete mechanical and footprint compatibility eliminates any need for PCB layout changes, thermal redesign, or mechanical rework. Engineers can seamlessly drop the VBA5415 into existing designs, enabling "plug-and-play" substitution. This drastically reduces the time, cost, and risk associated with the component qualification and design verification process, allowing for rapid production line implementation.
Local Supply Chain Assurance and Responsive Support
Choosing VBA5415 means liberating your supply chain from international logistics uncertainties and long lead times. Manufactured domestically, VBsemi guarantees stable, scalable production and significantly shorter delivery cycles. Coupled with local inventory, this ensures your production schedules remain uninterrupted. Furthermore, VBsemi provides dedicated, responsive technical support, offering comprehensive documentation, application notes, and direct engineer assistance to ensure a smooth and successful transition from the SH8M24TB1 to the VBA5415.
From DC-DC converters and motor drives to power distribution switches, the VBA5415 stands as the superior domestic alternative to the ROHM SH8M24TB1. By combining enhanced electrical performance, flawless package compatibility, and guaranteed supply stability, the VBA5415 is more than just a replacement—it is a strategic upgrade for your product's reliability, efficiency, and supply chain resilience.
