AON7421 Description

Short technical summary and product information.

AON7421 is a P-Channel MOSFET manufactured by AOS. It has a drain-source breakdown voltage of -20V and supports a continuous drain current of -50A at a case temperature of 25°C. The device is supplied in a DFN3.3x3.3-8L surface-mount package.

The MOSFET features a maximum static drain-source on-resistance of 4.6mΩ at VGS=-10V, 5.8mΩ at VGS=-4.5V, and 9mΩ at VGS=-2.5V. Typical gate charge is 44nC at VGS=4.5V and 95nC at VGS=10V. Input, output, and reverse transfer capacitances are 4550pF, 823pF, and 563pF, respectively, at VDS=-10V.

Maximum power dissipation is 83W at TC=25°C, with junction-to-case and junction-to-ambient thermal resistances of 1.1°C/W and 16°C/W. The device operates over a junction temperature range of -55°C to 150°C, making it suitable for power management circuits that require a high-current P-channel switch.
