Infineon Technologies IPG20N06S3L-23

Overview

IPG20N06S3L-23 from Infineon Technologies is a dual-channel N-channel logic-level enhancement-mode MOSFET in PG-TDSON-8-4 package, rated for 55 V V_DS, 20 A continuous drain current per channel at T_C = 25 °C, and 23 mΩ max R_DS(on) at V_GS = 10 V. It is AEC-Q101 qualified, supports 175 °C operation, and is used in automotive DC-DC converters and motor control half-bridges.

For engineers reviewing the IPG20N06S3L-23 datasheet, IPG20N06S3L-23 pinout, IPG20N06S3L-23 application, or IPG20N06S3L-23 equivalent, key selection criteria include R_DS(on) at 5 V gate drive, avalanche energy (110 mJ), thermal resistance (3.3 K/W j-c), diode forward voltage (1.0–1.3 V), and MSL1 reflow compatibility.

Technical Context

This dual N-channel MOSFET integrates two identical silicon die in a single thermally optimized PG-TDSON-8-4 leadless package with exposed drain pad. Each channel operates independently with fully characterized gate charge (Q_g = 32–42 nC), low Crss (270–410 pF), and fast switching (t_r = 35 ns, t_f = 75 ns) under 10 V gate drive.

Its logic-level gate threshold (V_GS(th) = 1.2–2.2 V) enables direct interfacing with 3.3 V/5 V microcontrollers. The integrated body diode exhibits low V_SD (1.0–1.3 V @ 20 A) and short t_rr (15 ns), supporting synchronous rectification and freewheeling in high-frequency power stages.

Key Specifications

Pinout & Package

PG-TDSON-8-4 is a surface-mount, leadless, thermally enhanced package with an exposed drain pad on the bottom side. Pin numbering follows standard JEDEC outline: pins 1–4 and 5–8 are symmetrical source/gate/drain terminals for each channel, with pins 1/5 = Source1/Source2, pins 2/6 = Gate1/Gate2, pins 3/7 = Drain1/Drain2, and pins 4/8 = Source1/Source2 (dual-source configuration).

FAQ

Is IPG20N06S3L-23 suitable for 48 V mild-hybrid systems?

No. Its 55 V V_DS rating provides only ~10% margin above nominal 48 V bus, insufficient for transients up to 60 V defined in ISO 16750-2. For 48 V systems, Infineon recommends IPG20N08S4L-23 (80 V rating) or similar higher-V_DS variants with adequate transient headroom.

Can both channels be paralleled to achieve 40 A current handling?

Not recommended. While electrically possible, mismatched R_DS(on) and thermal coupling between channels cause unequal current sharing. Derating to ≤25 A total is required if paralleling is attempted, and dedicated single-die alternatives like IPB120N04S4-02 are preferred for higher current.

What is the maximum gate resistor value for reliable 500 kHz switching?

Based on Q_g = 32–42 nC and t_r/t_f targets ≤50 ns, gate resistor must be ≤10 Ω when driven by a 2 A peak gate driver. With typical 1 A drivers, R_G should be 4.7–6.8 Ω to maintain timing integrity and minimize switching losses.

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

Yes. With t_rr = 15 ns and Q_rr = 15 nC, the body diode enables efficient synchronous rectification up to ~300 kHz in CCM. However, for >400 kHz operation, external Schottky diodes are advised to reduce recovery-related losses and EMI.
