Product details
Overview
IPB22N03S4L15ATMA1 from Infineon Technologies is an N-channel enhancement-mode automotive-qualified MOSFET in PG-TO263-3-2 package, rated for 30 V VDS, 22 A continuous drain current at TC = 25 °C, and ultra-low 14.6 mΩ max RDS(on) at VGS = 10 V. It is 100% avalanche tested and qualified to AEC-Q101 for under-hood motor control and DC-DC converter primary-side switching.
For engineers reviewing the IPB22N03S4L15ATMA1 datasheet, IPB22N03S4L15ATMA1 pinout, IPB22N03S4L15ATMA1 application, or IPB22N03S4L15ATMA1 equivalent, key selection criteria include its 4.9 K/W RthJC, 175 °C maximum junction temperature, 20 mJ single-pulse avalanche energy, and SMD-compatible thermal performance on 6 cm² PCB copper area.
Technical Context
This OptiMOS®-T2 power transistor uses trench-gate technology optimized for low conduction loss and fast switching in 12 V automotive systems. Its gate threshold voltage (1.0–2.2 V) enables robust drive with standard logic-level controllers, while its 11–14 nC total gate charge supports efficient PWM operation up to several hundred kHz.
The device integrates a co-packaged body diode with 0.6–1.3 V forward voltage at 22 A and 12 ns reverse recovery time, enabling synchronous rectification and freewheeling in buck converters and H-bridge motor drivers without external diodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - Maximum blocking voltage for 12 V battery rail applications with margin against load dump transients |
| RDS(on) max | 14.6 mΩ @ VGS = 10 V - Enables ≤3.2 W conduction loss at 22 A, reducing heatsink requirements |
| ID cont. | 22 A @ TC = 25 °C - Rated for high-current DC-DC phases and BLDC motor phase legs |
| EAS | 20 mJ - Confirmed single-pulse avalanche capability supports inductive turn-off stress in motor drives |
| RthJC | 4.9 K/W - Enables direct thermal path to heatsink; allows 31 W power dissipation at 25 °C case temperature |
| Qg | 11–14 nC - Low gate drive power requirement compatible with standard gate drivers (e.g., 1EDN7512B) |
| tr/tf | 2 ns / 2 ns - Fast switching minimizes overlap loss in hard-switched topologies |
Pinout & Package

FAQ
What is the maximum allowable gate-source voltage for IPB22N03S4L15ATMA1?
The absolute maximum VGS is ±16 V per datasheet Rev. 2.0. Operation above ±12 V is not recommended for long-term reliability. Gate drive circuits must limit transient overshoot using clamping diodes or RC snubbers, especially in high-dV/dt environments like motor inverters.
Does IPB22N03S4L15ATMA1 require a gate resistor, and what value is recommended?
Yes - a gate resistor is required to control dV/dt and suppress oscillation. For 22 A switching at 500 kHz, a 3.5 Ω resistor is validated in Infineon's ANPS071E. Lower values (≤2.2 Ω) increase EMI risk; higher values (>10 Ω) degrade switching speed and increase losses.
Can IPB22N03S4L15ATMA1 be used in parallel configurations?
Yes - its positive temperature coefficient for RDS(on) (increasing ~0.5%/°C) enables stable current sharing. Layout symmetry, matched gate drive paths, and individual source resistors (10–22 mΩ) are required to balance dynamic current distribution during switching transitions.
Is the drain tab electrically isolated from the package leads?
No - the drain is internally connected to the exposed metal tab. This tab must be soldered to a PCB copper pour serving as both thermal interface and electrical drain node. Electrical isolation requires insulating thermal pads or ceramic substrates if mounting to a common heatsink shared with other devices.
