In low-voltage signal switching, load management, and low-power circuit applications such as battery-powered devices, portable electronics, communication modules, and IoT sensor interfaces, MCC's BSS138-TP, with its compact design, low on-resistance, and surface-mount packaging, has been a widely adopted choice for engineers globally. However, in the current landscape marked by supply chain uncertainties and rising procurement complexities, this imported component presents challenges such as extended lead times, cost volatility, and limited technical support. This situation drives the urgent need for a reliable, high-performance domestic alternative that ensures supply chain security and cost optimization without compromising design integrity.
VBsemi, leveraging its expertise in semiconductor design, introduces the VB162K N-channel MOSFET. This product is meticulously engineered as a direct, pin-to-pin replacement for the BSS138-TP, offering superior electrical parameters, full package compatibility, and the reliability of local manufacturing. It provides a seamless upgrade path for designs requiring enhanced performance and stability.
Enhanced Electrical Parameters for Greater Design Headroom and Efficiency.
Tailored to outperform the BSS138-TP, the VB162K delivers significant improvements across key specifications, ensuring robust operation and greater design flexibility:
Higher Voltage Rating: The drain-source voltage (VDS) is increased to 60V, offering a 20% improvement over the original 50V. This provides a wider safety margin against voltage spikes and transients, enhancing system reliability in sensitive electronic applications.
Increased Current Capability: The continuous drain current (ID) is rated at 0.3A (300mA), a substantial 36% increase over the BSS138-TP's 220mA. This allows the VB162K to handle higher load currents comfortably, supporting more demanding circuit requirements.
Lower On-State Resistance: With a typical RDS(ON) of 2800mΩ (2.8Ω) at VGS=10V, the VB162K offers lower conduction loss compared to the BSS138-TP's 3.5Ω. This improvement translates directly into higher efficiency, reduced heat generation, and potentially longer battery life in portable applications.
Optimized Gate Characteristics: The device features a standard gate threshold voltage (Vth) of 1.7V and supports a gate-source voltage (VGS) of ±20V, ensuring easy drive compatibility with common logic levels and providing good noise immunity to prevent false triggering.
Advanced Trench Technology for Reliable Performance.
The VB162K utilizes advanced Trench MOSFET technology, which enables its excellent combination of low RDS(ON) and compact size. This technology ensures stable and fast switching performance, making it ideal for high-frequency signal switching applications. The device is designed to meet rigorous quality standards, offering high reliability for long-term operation in various environmental conditions.
Seamless Drop-In Replacement with SOT-23-3 Package.
The VB162K is offered in the industry-standard SOT-23-3 surface-mount package, which is mechanically and footprint compatible with the BSS138-TP. This complete package compatibility enables a true "drop-in" replacement, requiring no modifications to the existing PCB layout, solder paste stencil, or assembly process. Engineers can quickly validate and integrate the VB162K, significantly reducing the time, cost, and risk associated with component substitution.
Local Supply Chain Assurance and Responsive Support.
Choosing the VB162K mitigates the risks associated with international component sourcing. VBsemi's domestic manufacturing ensures stable supply, shorter lead times (typically within weeks), and competitive pricing protected from currency fluctuations. Furthermore, customers benefit from direct access to VBsemi's responsive technical support team, which can provide prompt assistance with design-in, validation, and any application-related queries, ensuring a smooth and successful transition.
From battery management systems and portable device protection circuits to interface drivers and power gating in low-voltage digital systems, the VB162K stands out as the superior domestic alternative to the MCC BSS138-TP. Its combination of enhanced electrical performance, perfect package compatibility, guaranteed supply stability, and local technical expertise makes it the intelligent choice for engineers seeking to future-proof their designs, optimize costs, and strengthen their supply chain resilience without sacrificing quality or performance.
