Detailed Specifications

The BSS138W H6327 features a drain-source voltage (V_DS) of 50V and a continuous drain current (I_D) of 220mA. The on-state resistance (R_DS(on)) is typically 3.5Ω at V_GS = 10V and 6Ω at V_GS = 4.5V. The gate-source threshold voltage (V_GS(th)) is between 0.8V and 1.5V, making it compatible with logic-level gate drive signals. The device is packaged in a SOT-323, which is a small surface-mount package. The MOSFET also boasts a fast switching speed. The input capacitance is low, which makes it easy to drive. Its construction incorporates materials and processes designed for robust performance under diverse operating conditions.

The low gate threshold voltage makes it directly compatible with many microcontrollers and other low-voltage control devices. Its small size is ideal for high-density circuit boards. The surface-mount package enables automated assembly, which helps reduce manufacturing costs. The BSS138W H6327 is a general-purpose MOSFET that provides a good balance of performance and cost for a wide range of applications.
