Infineon Technologies IPAN80R450P7XKSA1

Overview

IPAN80R450P7XKSA1 from Infineon is an 800V N-channel superjunction MOSFET in PG-TO220 FP package, optimized for hard/soft-switching flyback and PFC stages. It delivers R_DS(on) = 0.45 Ω (max), Q_g = 24 nC (typ), V_GS(th) = 3 V (typ), and integrated Zener ESD protection. Used in LED lighting drivers, low-power adapters, and auxiliary power supplies.

For engineers reviewing the IPAN80R450P7XKSA1 datasheet, IPAN80R450P7XKSA1 pinout, IPAN80R450P7XKSA1 application, or IPAN80R450P7XKSA1 equivalent, key selection criteria include 800V blocking capability, low gate charge for high-frequency switching, tight V_GS(th) tolerance (±0.5 V), and rugged dv/dt performance (100 V/ns).

Technical Context

This CoolMOS™ P7 device employs superjunction architecture with optimized charge balancing to achieve best-in-class R_DS(on) × E_oss figure of merit. Its 3 V gate threshold enables direct drive from 3.3 V/5 V controllers without level-shifting.

The integrated Zener diode provides ±1 µA gate-source leakage protection per JEDEC standards, and its 4.4 °C/W R_thJC supports thermal management in compact, convection-cooled designs up to 29 W at T_C = 25°C.

FAQ

What is the maximum continuous drain current for IPAN80R450P7XKSA1 at 100°C case temperature?

The maximum continuous drain current is 7.1 A at T_C = 100°C, as specified in Table 2 of the datasheet. This rating accounts for thermal derating due to junction-to-case thermal resistance (4.4 °C/W) and maximum junction temperature (150°C). Operation above this current requires active cooling or reduced duty cycle to maintain safe operating area compliance.

Does IPAN80R450P7XKSA1 require external gate protection?

No-this device integrates a Zener diode for gate-source ESD protection (HBM Class 2), eliminating the need for external TVS or resistor-Zener networks. Gate leakage remains ≤1 µA at V_GS = 20 V, confirming robust internal clamping without compromising drive integrity or adding board space.

Can IPAN80R450P7XKSA1 be paralleled with identical units?

Yes-its tight V_GS(th) distribution (±0.5 V) and low gate charge enable stable current sharing. However, Infineon recommends using ferrite beads on individual gate lines or separate totem-pole drivers to suppress oscillation and ensure simultaneous switching, especially in high-di/dt layouts.

Is the drain tab electrically isolated in the PG-TO220 FP package?

No-the tab is internally connected to Pin 2 (Drain) and is not electrically isolated. It must be mounted to a heatsink with appropriate insulating hardware (e.g., mica washer or silicone pad) if the heatsink is at a different potential than the drain node, to prevent short-circuit or safety violation.
