A19T datasheet transistor


The A19T uses advanced trench technology to provide excellent RDS(ON), low gate charge and operation with gate voltages as low as 2.5V. This device is suitable for use as a
load switch or in PWM applications.


1. VDS = -30V,ID = -4.2A
RDS(ON) < 130mΩ @ VGS=-2.5V
RDS(ON) < 75mΩ @ VGS=-4.5V
RDS(ON) < 55mΩ @ VGS=-10V
2. High power and current handing capability
3. Lead free product is acquired
4. Surface mount package
