Infineon Technologies IPL65R340CFDAUMA1

Overview

IPL65R340CFDAUMA1 from Infineon Technologies is a 650 V, 0.34 Ω R_DS(on) CoolMOS™ CFD2 superjunction power MOSFET in ThinPAK 8x8 package, featuring 41 nC total gate charge, 95 ns reverse recovery time, and ultra-fast body diode (900 A/µs di_F/dt). It serves as a high-efficiency primary-side switch in resonant LLC converters for server PSUs and telecom rectifiers.

For engineers reviewing the IPL65R340CFDAUMA1 datasheet, IPL65R340CFDAUMA1 pinout, IPL65R340CFDAUMA1 application, or IPL65R340CFDAUMA1 equivalent, key selection criteria include its 700 V V_DS @ T_jmax, 32 A pulsed drain current, 3.5 µJ E_oss @ 400 V, and validated commutation ruggedness for ZVS/ZCS topologies.

Technical Context

This device implements Infineon's second-generation CoolMOS™ CFD superjunction architecture with optimized charge balance and trench-gate design, enabling simultaneous low conduction loss (R_DS(on) × Q_g = 14.0 Ω·nC) and fast, soft body diode recovery. Its 900 A/µs di_F/dt rating supports hard-switched and resonant operation without external snubbers.

The ThinPAK 8x8 leadless SMD package delivers 1.2 °C/W junction-to-case thermal resistance and <1 nH source inductance-critical for minimizing voltage overshoot and oscillation in high-frequency (>100 kHz) switching stages used in compact 1U server power supplies.

FAQ

What is the maximum continuous drain current for IPL65R340CFDAUMA1 at 100°C case temperature?

The maximum continuous drain current is 6.9 A at T_C = 100°C, as specified in Table 2 of the Rev. 2.1 datasheet. This value is thermally limited by the 1.2 °C/W R_thJC and 150°C maximum junction temperature, and assumes proper PCB copper area for heat dissipation.

Does IPL65R340CFDAUMA1 support gate drive with 12 V logic-level controllers?

Yes-the gate threshold voltage is 3.5–4.5 V (V_GS(th)), and the gate plateau occurs at ~6.4 V, making it fully compatible with standard 12 V gate drivers. A 10 V gate drive ensures full enhancement with margin, and the 4.5 Ω internal gate resistance simplifies external gate resistor selection.

How does the ThinPAK 8x8 package affect PCB layout versus D²PAK?

ThinPAK 8x8 reduces footprint from 150 mm² (D²PAK) to 64 mm² and height from 4.4 mm to 1 mm, enabling denser layouts and improved airflow in 1U systems. Its symmetric pinout and exposed drain pad require thermal via placement beneath the pad and strict adherence to IPC-7351B land pattern for solder joint reliability.

Can IPL65R340CFDAUMA1 replace older CoolMOS™ CFD parts in existing designs?

Yes-it is a direct drop-in replacement for IPL65R340CFD (same marking, same package, same pinout) with identical R_DS(on), Q_g, and diode specs. The "AUMA1" suffix denotes tape-and-reel packaging per AEC-Q200-compliant logistics, with no electrical or thermal changes from Rev. 2.1 silicon.
