Infineon BSS214NH6327XTSA1: A Compact Powerhouse for Logic-Level Switching

The Infineon BSS214NH6327XTSA1 represents a highly optimized N-Channel MOSFET engineered for efficient low-voltage control in modern electronic circuits. As an enhancement mode device, it remains off until a sufficient positive voltage is applied to the gate, making it ideal for use as a electronically controlled switch. Its defining characteristic is its logic-level compatibility, meaning it can be fully turned on (or enhanced) with gate-source voltages (V_GS) as low as 2.5 V, making it perfectly suited for direct interfacing with microcontrollers, FPGAs, and other digital logic circuits that typically operate at 3.3 V or 5 V.

Housed in a space-saving SC-74 (SOT-457) package, this MOSFET is designed for high-density PCB designs where board real estate is at a premium. Despite its miniature size, it delivers robust performance with a continuous drain current (I_D) of up to 2 A and features an exceptionally low on-state resistance (R_DS(on)) of just 90 mΩ (max. at V_GS = 4.5 V). This low resistance is critical for minimizing conduction losses, leading to higher efficiency and reduced heat generation in applications such as load switching, power management functions, and DC-DC conversion.

Key performance metrics include a drain-source voltage (V_DS) rating of 60 V, providing ample headroom for a wide range of low-power systems. Its fast switching speeds further enhance its suitability for PWM (Pulse Width Modulation) control, which is fundamental in motor drivers and LED dimmers.

ICGOOODFIND: The Infineon BSS214NH6327XTSA1 is an outstanding choice for designers seeking a reliable, efficient, and compact logic-level MOSFET to drive loads from digital signals, offering an excellent balance of low R_DS(on), high current capability, and a minimal footprint.
