Product details

Overview

IPG20N04S408ATMA1 from Infineon Technologies is a dual-channel AEC-Q101-qualified N-channel enhancement-mode MOSFET in PG-TDSON-8 package, rated for 40 V V_DS, 7.6 mΩ R_DS(on) at 10 V_GS, and 20 A continuous drain current per channel. It operates up to 175 °C, supports 80 A pulsed drain current, and integrates a robust body diode with 36 ns t_rr and 34 nC Q_rr, targeting automotive DC-DC converters and motor control inverters.

For engineers reviewing the IPG20N04S408ATMA1 datasheet, IPG20N04S408ATMA1 pinout, IPG20N04S408ATMA1 application, or IPG20N04S408ATMA1 equivalent, key selection criteria include its 2.3 K/W R_thJC, 100% avalanche-tested ruggedness (230 mJ E_AS), dual-channel layout for half-bridge integration, and MSL1 reflow compatibility - all critical for high-reliability automotive power stages.

Technical Context

This OptiMOS™-T2 device uses trench-gate superjunction technology optimized for low conduction and switching losses in 12 V/24 V automotive systems. Its dual N-channel configuration enables synchronous rectification and compact half-bridge designs without external level-shifting circuitry.

The MOSFET features gate plateau voltage of 5.2 V, total gate charge of 36 nC max, and input/output capacitances (C_iss = 2940 pF, C_oss = 720 pF) tailored for fast switching at 100–500 kHz frequencies while maintaining EMI control via controlled dV/dt.

Key Specifications

FAQ

Is IPG20N04S408ATMA1 pin-compatible with earlier OptiMOS™-T1 dual-channel MOSFETs?

No. IPG20N04S408ATMA1 uses PG-TDSON-8 with internally paralleled drain/source pins, whereas OptiMOS™-T1 dual variants (e.g., IPG20N04S208A) use PG-TDSON-8 with discrete pin assignments. Layout redesign is required due to different internal connectivity and thermal pad routing.

What is the maximum recommended gate resistor value for 200 kHz switching?

For 200 kHz operation with 1-A peak gate driver, a 10 Ω series gate resistor is recommended. This balances switching speed (t_r/t_f ≈ 5/13 ns) against ringing suppression, given the device's 36 nC Q_g and 17 pF Crss, while keeping EMI within CISPR 25 Class 5 limits.

Does the body diode support continuous reverse conduction in synchronous rectification mode?

Yes. The integrated body diode is rated for 20 A continuous forward current (I_S) and 80 A pulsed (I_S,pulse) at T_C = 100 °C, with V_SD = 0.9–1.3 V at 17 A. Its 34 nC Q_rr and 36 ns t_rr ensure low-loss reverse recovery during hard-commutated synchronous rectification.

Can IPG20N04S408ATMA1 be used in parallel configurations for higher current?

Yes, but only with matched gate drive and symmetrical PCB layout. The device exhibits positive R_DS(on) temperature coefficient above 25 °C (R_DS(on) increases ~0.5%/°C), enabling inherent current sharing. Thermal coupling between channels must be minimized to avoid imbalance beyond ±15% at full load.
