APT34M120J Description

Short technical summary and product information.

The APT34M120J is a high-voltage N-Channel MOSFET from Microchip Technology, utilizing Power MOS 8 technology. It features a minimum drain-source breakdown voltage of 1200V and a continuous drain current of 35A at 25°C (22A at 100°C). The maximum drain-source on-resistance is 0.29Ω at Vgs=10V. The device offers low gate charge (560 nC maximum) and ultra-low reverse transfer capacitance (215 pF typical), enabling fast switching with reduced EMI. With a high single pulse avalanche energy rating of 2700 mJ, it is suitable for robust applications. The MOSFET is rated for 960W power dissipation at 25°C case temperature and operates over a junction temperature range of -55°C to 150°C. It comes in a SOT-227-4 (miniBLOC) chassis mount package with 2500V isolation voltage. The device is RoHS compliant.
