In compact, low-voltage application scenarios such as portable device power management, load switches, signal switching, and battery-powered circuits, ROHM's EM6K31T2R, with its high-speed switching capability, low-voltage drive compatibility (2.5V), and ultra-small EMT6 package, has been a go-to choice for engineers designing space-constrained and power-sensitive products. However, in the current climate of global supply chain volatility and extended lead times for niche components, sourcing this imported MOSFET can present challenges: potential procurement delays, cost uncertainties, and limited local technical support. This drives the urgent need for a reliable, readily available domestic alternative that ensures design continuity and supply chain security.
Responding to this market demand, VBsemi leverages its expertise in power semiconductor miniaturization to introduce the VBTA3615M, a dual N-channel MOSFET meticulously engineered as a direct and superior replacement for the EM6K31T2R. It offers enhanced electrical parameters, full package compatibility, and the robust backing of a local supplier, providing a seamless and upgraded solution for modern compact electronic designs.
Enhanced Electrical Performance for Greater Design Margin and Efficiency
Tailored as a pin-to-pin upgrade to the EM6K31T2R, the VBTA3615M delivers significant improvements in key specifications, offering designers more headroom and efficiency:
Higher Current Handling: The continuous drain current (Id) is rated at 0.3A, a 20% increase over the EM6K31T2R's 0.25A. This provides a safer margin for applications with current spikes or allows for design towards higher load capacities.
Drastically Lower Conduction Losses: The VBTA3615M features a remarkably low on-state resistance (RDS(on)) of 1200mΩ (@10V Vgs), which is half of the 2400mΩ (@10V Vgs) of the original part. This 50% reduction directly translates to lower voltage drop, reduced power dissipation, and improved overall system efficiency, particularly critical in battery-operated devices.
Optimized for Modern Low-Voltage Systems: With a gate threshold voltage (Vth) of 1.7V, the VBTA3615M is exceptionally well-suited for driving by low-voltage microcontroller GPIOs (3.3V or even lower) commonly found in today's portable and IoT devices, ensuring reliable and robust switching.
Advanced Trench Technology Ensures Reliable High-Speed Operation
The EM6K31T2R is valued for its high-speed switching performance. The VBTA3615M is built using VBsemi's advanced Trench technology, which is inherently designed for fast switching and low gate charge. This ensures the VBTA3615M not only matches but can potentially exceed the switching performance of the original part, making it ideal for applications requiring fast signal control or power path switching. The device's robust design supports a gate-source voltage (Vgs) of ±20V, offering strong protection against gate voltage spikes and enhancing overall circuit reliability in noisy environments.
Seamless SC75-6 Package Compatibility for Zero-Risk Replacement
A primary concern in component substitution is the redesign effort required. The VBTA3615M eliminates this hurdle entirely. It is offered in the industry-standard SC75-6 package, which is physically and pin-to-pin identical to the EMT6 package of the EM6K31T2R. Engineers can directly drop the VBTA3615M into existing PCB footprints without any modification to the layout, solder paste stencil, or assembly process. This "plug-and-play" compatibility drastically reduces qualification time, eliminates re-tooling costs, and accelerates the time-to-market for end products.
Local Supply Chain Resilience and Responsive Technical Support
Unlike imported components subject to international logistics and allocation uncertainties, the VBTA3615M benefits from VBsemi's domestic manufacturing and streamlined logistics. This guarantees stable, predictable supply with significantly shorter lead times, shielding your production from external disruptions. Furthermore, VBsemi provides immediate, local technical support. Our engineering team can offer swift assistance with substitution验证, application troubleshooting, and optimization, ensuring a smooth and supported transition away from the imported component.
From portable consumer electronics and IoT modules to handheld medical devices and battery management systems, the VBTA3615M stands as the optimal domestic alternative to the ROHM EM6K31T2R. Its combination of superior electrical performance (higher current, lower RDS(on)), perfect package compatibility, and guaranteed local supply makes it not just a substitute, but a strategic upgrade. Choosing VBTA3615M empowers designers to enhance product performance while fortifying their supply chain—all with zero redesign risk.
