Onsemi FDD8424H Dual N & P Channel MOSFET, TO-252, 40V, 9A

The Onsemi FDD8424H is a 40V dual N and P channel PowerTrench MOSFET rated at 9A, housed in a compact TO-252 (DPAK) package with 5 pins.

This MOSFET is engineered to minimise on-state resistance and maintain low gate charge for efficient switching performance. It combines a small gate charge (QG), a small reverse recovery charge (Qrr) and a soft reverse recovery body diode, which contributes to fast switching for synchronous rectification in AC/DC power supplies.

Key Features

• Complementary N and P channel configuration
• Drain source voltage (N and P channel): 40V
• Continuous drain current (N and P channel): 9A
• Low on-state resistance (N and P channel): 0.019 ohm
• Shielded-gate structure that provides charge balance
• Small gate charge and soft body diode
• Fast switching for synchronous rectification

Performance Notes

The shielded-gate structure provides charge balance, which supports the device's switching behaviour. The soft body diode performance helps eliminate the need for snubber circuits or higher voltage rating MOSFETs by minimising undesirable voltage spikes in synchronous rectification.

Physical Details

• Package: TO-252 (DPAK) with 5 pins
• Dimensions (W x D x H): 3.3 x 1.5 x 4.3
