This post explains for the MOSFET transistor A19T.
See the preview image and the PDF file for more information.
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
1. PWM applications
2. Load switch
3. Power management
4. P/N suffix V means AEC-Q101 qualified, e.g:RM3401V
