The IPD530N15N3GATMA1: Gate charge totals 12 nC at 10 V — low enough that a 3.3 V MCU GPIO driving a level shifter can switch it at moderate frequency without a dedicated gate driver IC. The 887 pF input capacitance at 75 V drain-source confirms the gate drive load is light.
175°C junction — where this part lives
The 68 W power dissipation at case temperature is the thermal budget for a TO-252 soldered to a standard copper pad; a larger pad or a heatsink on the tab pulls the RthJA down and lets the part deliver closer to the full 21 A in a 70°C ambient.
Gate drive and switching profile
The drive voltage window is 8 V to 10 V for minimum on-resistance — the 4 V threshold at 35 µA drain current means the part is fully enhanced at 10 V but will not turn on with a 3.3 V logic signal. The ±20 V maximum gate-source rating gives margin for ringing on a long PCB trace.
Package and board integration
The PG-TO252-3 (DPak) surface-mount package has two leads plus the exposed tab. The 0.50 mm lead pitch is standard for this footprint; the part is available in Tape & Reel for automated pick-and-place.
