Infineon Technologies IPG20N10S4L35ATMA1

Overview

IPG20N10S4L35ATMA1 from Infineon Technologies is a dual-channel AEC-Q101-qualified N-channel logic-level MOSFET in PG-TDSON-8-4 package, rated for 100 V V_DS, 20 A continuous drain current (T_C = 25 °C), and 35 mΩ max R_DS(on) at V_GS = 10 V. It operates up to 175 °C junction temperature and is fully avalanche tested-designed for automotive body control modules and DC-DC converters requiring robust switching under high thermal stress.

For engineers reviewing the IPG20N10S4L35ATMA1 datasheet, IPG20N10S4L35ATMA1 pinout, IPG20N10S4L35ATMA1 application, or IPG20N10S4L35ATMA1 equivalent, key selection criteria include its 4.5 V logic-level gate drive compatibility, 3.5 K/W R_thJC, dual-channel layout for half-bridge or load-switch redundancy, and MSL1 reflow rating for automotive PCB assembly.

Technical Context

This OptiMOS™-T2 power transistor integrates two independent N-channel enhancement-mode MOSFETs in a single thermally optimized surface-mount package. Its gate threshold voltage (1.1–2.1 V) enables direct microcontroller-level drive, while the 35 mΩ R_DS(on) at 10 V and 29 mΩ typ. at 17 A ensures low conduction loss in 12 V/24 V automotive systems.

The device features 850–1105 pF input capacitance, 30–60 pF reverse transfer capacitance, and 13.4–17.4 nC total gate charge-optimized for fast switching with controlled EMI in synchronous rectification and motor gate-drive applications. Its integrated body diode supports bidirectional current flow with 1.0–1.3 V forward voltage at 17 A and 50 ns reverse recovery time.

Key Specifications

Pinout & Package

IPG20N10S4L35ATMA1 uses the PG-TDSON-8-4 package: thermally enhanced 8-pin exposed-drain DSO-style leadframe with 4 mm × 3.3 mm footprint and 0.65 mm pitch. Drain terminals are internally paralleled across pins 1–3 and 5–7 for low-inductance, high-current routing.

FAQ

What is the maximum gate-source voltage rating for IPG20N10S4L35ATMA1?

The absolute maximum gate-source voltage is ±16 V. Exceeding this value risks permanent gate oxide damage. Designers must ensure gate drive circuits limit transient overshoot using clamping diodes or resistor-capacitor snubbers, especially in high-dV/dt environments like motor drives.

Does IPG20N10S4L35ATMA1 support parallel operation of both channels?

No-channels are electrically isolated with separate source terminals (Pin 4 and Pin 8). They cannot be paralleled without external current-sharing components. The dual-channel architecture is intended for independent switching functions such as half-bridge legs or redundant load paths.

Is the body diode in IPG20N10S4L35ATMA1 suitable for continuous conduction mode (CCM) operation?

Yes-the integrated body diode is rated for 20 A continuous forward current and 80 A pulsed current. Its 1.0–1.3 V forward voltage and 50 ns reverse recovery time support CCM in synchronous rectifiers, though external Schottky diodes may be preferred for ultra-low V_F requirements.

How does the 3.5 K/W R_thJC translate to PCB layout requirements?

A 3.5 K/W junction-to-case thermal resistance assumes mounting on a 40 mm × 40 mm FR4 PCB with 6 cm² copper area connected to the exposed drain pad. To achieve this, designers must use ≥70 µm thick copper, multiple thermal vias under the pad, and avoid solder mask coverage on the thermal land.
