Infineon Technologies IPG20N10S4L22AATMA1

Overview

IPG20N10S4L22AATMA1 from Infineon Technologies is a dual-channel AEC-Q101-qualified N-channel logic-level MOSFET in PG-TDSON-8-10 package, rated for 100 V V_DS, 20 mΩ R_DS(on) at V_GS = 10 V and I_D = 17 A, with 175 °C maximum junction temperature and 100% avalanche tested - deployed in automotive body control modules and 12 V/24 V DC-DC converters.

For engineers reviewing the IPG20N10S4L22AATMA1 datasheet, IPG20N10S4L22AATMA1 pinout, IPG20N10S4L22AATMA1 application, or IPG20N10S4L22AATMA1 equivalent, key selection criteria include logic-level gate drive compatibility (V_GS(th) = 1.1–2.1 V), low R_DS(on) thermal stability up to 175 °C, dual-channel layout for half-bridge or load-switch redundancy, and MSL1 reflow capability for high-reliability automotive PCB assembly.

Technical Context

This dual N-channel MOSFET integrates two identical enhancement-mode silicon die in a single thermally optimized PG-TDSON-8-10 leadless package with exposed drain pad. Each channel supports 20 A continuous drain current at T_C = 25 °C and delivers 22 mΩ max R_DS(on) at V_GS = 4.5 V, enabling direct microcontroller GPIO drive without level-shifting.

The device features 1350–1755 pF input capacitance (C_iss) and 42–84 pF reverse transfer capacitance (C_rss), with 5.6 nC typical Q_gs and 9.6 nC max Q_gd, supporting fast switching (t_r = 3 ns, t_f = 18 ns) under 11 Ω gate resistance - critical for synchronous rectification and PWM motor control.

Key Specifications

Pinout & Package

PG-TDSON-8-10 is a 5 mm × 6 mm leadless surface-mount package with exposed drain pad (pins 1–4 and 5–8 are source terminals; pin 7 is gate of channel 1; pin 8 is gate of channel 2). Thermal performance relies on soldered copper area (≥6 cm²) beneath the drain pad.

FAQ

What is the maximum gate-source voltage rating for IPG20N10S4L22AATMA1?

The absolute maximum gate-source voltage is ±16 V, verified per datasheet Section 2 (Maximum Ratings). Exceeding this value risks permanent oxide damage to the gate dielectric. Recommended operating range is –10 V to +12 V for reliable long-term performance, especially under transient conditions such as ESD or gate driver overshoot.

Does IPG20N10S4L22AATMA1 include an integrated body diode, and what are its key parameters?

Yes, each channel includes a monolithic body diode with 1.0–1.3 V forward voltage at I_F = 17 A and T_j = 25 °C, 55 ns reverse recovery time, and 100 nC reverse recovery charge. These values are measured under standardized conditions (V_R = 50 V, di/dt = 100 A/µs) and enable efficient freewheeling in inductive load circuits without external diodes.

How is thermal performance validated for the PG-TDSON-8-10 package?

Thermal resistance is specified as R_thJC = 2.5 K/W (junction-to-case), measured with the device mounted on a 40 mm × 40 mm × 1.5 mm FR4 PCB with 6 cm² copper area connected to the exposed drain pad. This value is confirmed via transient dual-interface testing (TDIT) per JEDEC JESD51-14 and applies only when the drain pad is fully soldered with minimum 0.15 mm solder thickness.

Can IPG20N10S4L22AATMA1 be used in parallel configurations, and what layout considerations apply?

Yes, the dual-channel architecture supports internal paralleling of both channels for 40 A total current, provided gate traces are symmetrical and source inductance is minimized. External paralleling with other units requires matched R_DS(on) (±5%), individual gate resistors (≤10 Ω), and Kelvin-source routing to ensure current sharing within ±10% across temperature and load ranges.
