Back to previous pageProduct introduction：
1. Product Introduction
KMA4D5P20XA-VB is a single P-channel MOSFET in SOT23-6 package, designed for low-voltage applications, with excellent switching performance and efficient conduction characteristics. Its **VDS is -30V**, which can provide reliable current switching capabilities in relatively low-voltage circuits. The device uses advanced trench technology to further reduce the on-resistance, thereby achieving higher efficiency and lower heat loss. The **VGS rating of the MOSFET is ±20V** and the gate threshold voltage is **-1.7V**, making it suitable for driving at relatively low control voltages. The device has a maximum drain current (ID) of **-4.8A** and has low on-resistance characteristics of **54mΩ@VGS=4.5V** and **49mΩ@VGS=10V**, respectively, which can provide stable performance under various load conditions.
