BSS138NH6433-VB Product details
Back to previous pageProduct introduction：
Still struggling with high conduction losses and logic level mismatch in small-signal switching circuits? Let VBsemi BSS138NH6433-VB solve your problems! This SOT23-3 packaged N-MOSFET, despite its small size, can reliably handle 0.3A current, and its 60V voltage rating covers most low-voltage control and interface circuits. Trench technology brings fast switching and low leakage characteristics. The on-resistance is as low as 2800mΩ when driven at 10V. With a wide ±20V gate voltage range, 3.3V/5V logic direct drive is easily achieved, making it the "level-shifting weapon" in an engineer's toolkit.
