Product details
Overview
IPB120P04P404ATMA1 from Infineon Technologies is a P-channel enhancement-mode MOSFET rated for -40 V VDS, 120 A continuous drain current at TC = 25 °C, and 2.9–3.8 mΩ RDS(on) at VGS = -10 V. It features AEC qualification, 175 °C maximum junction temperature, and 100% single-pulse avalanche testing-designed for high-current automotive power distribution and battery disconnect circuits.
For engineers reviewing the IPB120P04P404ATMA1 datasheet, IPB120P04P404ATMA1 pinout, IPB120P04P404ATMA1 application, or IPB120P04P404ATMA1 equivalent, key selection criteria include its -40 V breakdown voltage, low RDS(on) in PG-TO263-3-2 package, thermal resistance of 1.1 K/W (junction-to-case), and compliance with automotive reliability standards including MSL1 reflow and 175 °C operation.
Technical Context
This device operates as a normally-off P-channel power switch with gate threshold voltage between -2.0 V and -4.0 V, enabling robust control using standard logic-level drivers in high-side configurations. Its dynamic parameters include 11.4 nC typical Qgs, 45 nC typical Qgd, and 181.5 nC total gate charge, supporting efficient switching in DC-DC converters and motor control H-bridges.
The integrated body diode exhibits 1.0–1.3 V forward voltage at -100 A and 25 °C, with 69 ns reverse recovery time and 95 nC Qrr, making it suitable for synchronous rectification and freewheeling in bidirectional power stages where controlled turn-off and low conduction loss are critical.

FAQ
What is the maximum allowable gate-source voltage for IPB120P04P404ATMA1?
The absolute maximum gate-source voltage is ±20 V. Operation beyond this range risks permanent gate oxide damage. For reliable long-term use, gate drive should be limited to -12 V to -15 V during switching and clamped to 0 V during off-state to prevent unintended turn-on from noise coupling.
Does IPB120P04P404ATMA1 require a gate resistor, and what value is recommended?
Yes-a gate resistor is required to control dV/dt and suppress oscillation. For 100 kHz PWM at 120 A, a 3.5 Ω resistor is validated in Infineon's reference design. Lower values increase switching speed but risk ringing; higher values reduce EMI but raise switching losses proportionally to Qg × fSW.
Can IPB120P04P404ATMA1 be used in parallel configurations?
Yes, but only with matched devices and symmetrical PCB layout. Thermal and gate drive imbalance must be minimized: use Kelvin source connections, individual gate resistors, and ensure <2 °C junction temperature difference between paralleled units to avoid current hogging and thermal runaway.
Is the body diode suitable for continuous freewheeling in an H-bridge?
Yes-the integrated diode is rated for -120 A continuous forward current and has been characterized for 69 ns trr and 95 nC Qrr. However, for high-frequency (>20 kHz) or high-di/dt applications, external Schottky or SiC diodes may be preferred to minimize reverse recovery losses and EMI.
