Infineon Technologies IPL65R165CFDAUMA2

Overview

IPL65R165CFDAUMA2 from Infineon Technologies is a 650 V, 21.3 A (T_C = 25 °C) N-channel superjunction MOSFET in ThinPAK 8x8 package, featuring R_DS(on) = 0.165 Ω (max), Q_g = 86 nC (typ), and ultra-fast body diode with dI_F/dt = 900 A/µs - engineered for high-efficiency resonant LLC and PFC stages in server power supplies and telecom rectifiers.

For engineers reviewing the IPL65R165CFDAUMA2 datasheet, IPL65R165CFDAUMA2 pinout, IPL65R165CFDAUMA2 application, or IPL65R165CFDAUMA2 equivalent, key selection criteria include commutation ruggedness (dI_F/dt = 900 A/µs), low E_oss (6.8 µJ @ 400 V), fast trr (140 ns), and industrial-grade JEDEC qualification - all critical for zero-voltage switching reliability and thermal stability in high-density SMPS designs.

Technical Context

This CoolMOS™ CFD2 device implements a charge-compensated superjunction structure enabling simultaneous reduction of conduction (R_DS(on) × Q_g FOM = 14.2 Ω·nC) and switching losses (E_oss = 6.8 µJ @ 400 V). Its optimized gate charge profile (Q_gd/Q_g = 55%) supports clean hard-switching transitions with minimal voltage overshoot.

The integrated ultra-fast body diode delivers 140 ns reverse recovery time and 8.8 A peak recovery current under 400 V/14 A conditions, eliminating need for external SiC Schottky catch diodes in half-bridge resonant topologies. Drain-source avalanche rating (E_AS = 614 mJ) ensures single-pulse robustness in overvoltage events.

Key Specifications

Pinout & Package

ThinPAK 8x8 (PG-VSON-4) is a leadless surface-mount package with 1 mm profile and 64 mm² footprint - 57% smaller area and 77% lower height than D²PAK. Drain is exposed on bottom side; terminals are arranged for minimal loop inductance in high-frequency layouts.

FAQ

What is the maximum continuous drain current for IPL65R165CFDAUMA2 at 100 °C case temperature?

The maximum continuous drain current is 13.5 A at T_C = 100 °C, as specified in Table 2 of the Rev. 2.1 datasheet. This value accounts for thermal derating due to junction-to-case thermal resistance (0.64 °C/W) and maximum junction temperature limit of 150 °C. Operation above this current requires active cooling or reduced ambient temperature.

Does IPL65R165CFDAUMA2 require a negative gate turn-off voltage?

No - the device operates with 0 V to +10 V or +13 V gate drive; negative turn-off voltage is not required or recommended. The gate threshold voltage is 3.5–4.5 V, and the maximum allowable gate-source voltage is ±30 V. Standard CMOS or dedicated gate drivers (e.g., 1EDN7512B) provide sufficient control without negative bias.

Can IPL65R165CFDAUMA2 replace older CoolMOS™ CFD parts in existing designs?

Yes - IPL65R165CFDAUMA2 is a direct replacement for IPL65R165CFD (same marking "65F6165", identical ThinPAK 8x8 package, and compatible pinout). Electrical specs are unchanged; the "AUMA2" suffix denotes tape-and-reel packaging per AEC-Q200-compliant logistics - no circuit or layout modifications needed.

What is the safe operating area (SOA) limitation at 80 °C case temperature?

At T_C = 80 °C, the SOA is defined by thermal limits rather than avalanche or secondary breakdown. For DC operation, maximum V_DS is ~320 V at 10 A (per Diagram 3); pulse operation up to 10 ms supports 400 V at 5 A. Derating follows the P_tot curve: 195 W at 25 °C linearly decreases to ~125 W at 80 °C case temperature.
