IPB180P04P4L02ATMA2 - 40V P-Channel 180A OptiMOS-P2 MOSFET | Infineon
MPN: IPB180P04P4L02ATMA2 ✓ Hoạt độngIPB180P04P4L02ATMA2 Tóm tắt
A P-Channel MOSFET is a voltage-controlled power transistor whose conduction channel is formed by negative charge carriers (holes) between source and drain. Compared with N-channel MOSFETs, P-channel parts simplify high-side switching by eliminating the charge pump or bootstrap circuit normally required to drive an N-channel high-side FET, which reduces BOM cost and PCB area. P-channel MOSFETs sit in the hierarchy: P-channel MOSFET -> MOSFET -> power transistor -> discrete semiconductor. The OptiMOS-P2 generation specifically targets the highest figure of merit for low-voltage (<=40 V) high-current switching applications.
Key specifications include a maximum drain-source voltage VDS of 40 V, continuous drain current ID of 180 A at Tc, pulsed avalanche current handling that supports motor-drive transients, and an extremely low typical on-state resistance RDS(on) of 2.4 mOhm at VGS = 10 V (according to Infineon's product summary page). The P-channel polarity and -10 V gate drive are standard for high-side load switching. PG-TO263-7-3 (D2PAK-6) is a 7-pin surface-mount package with a large metal tab that doubles as the drain connection and provides a low-thermal-resistance path to the PCB.
The OptiMOS-P2 trench technology uses an advanced cell pitch and a P-epi drain structure to minimize the RDS(on) x Qg figure of merit. The die is optimized for high peak current handling and low conduction loss, and is screened to Infineon's automotive-grade reliability flow. The -02 suffix denotes a specific VGS(th) and RDS(on) bin within the OptiMOS-P2 family.
Typical applications include high-side load switches in 12 V / 24 V automotive board nets, motor-bridge switches for small DC motors and pumps, reverse-battery protection FETs, and power-ORing switches in redundant supply architectures. The P-channel topology makes it particularly attractive as a high-side switch that is driven directly from a logic-level MCU without needing a level-shifter.
When designing with this part, note that the source pin sits at the load (system voltage) side, so the tab/drain is the low-side (ground) terminal. Gate drive must reach at least 10 V below the source for full enhancement. For thermal management at 150 W PDC, copper-pour area under the tab should be sized to keep Tj below 175 C at worst-case continuous load.

Ứng dụng tiêu biểu
IPB180P04P4L02ATMA2 phù hợp cho 6 Áp dụngs: 12V Automotive High-Side Load Switch, 24V Truck/Powertrain Motor Bridge Switch, Reverse-Battery / Load-Dump Protection, Server ORing / Hot-Swap Power Switch, Industrial 24V Solenoid/Valve Driver, USB PD / High-Current Charging Switch.
12V Automotive High-Side Load Switch
The IPB180P04P4L02ATMA2 is ideal as a high-side load switch in 12 V automotive board nets because its P-channel polarity eliminates the need for a charge-pump or bootstrap circuit to drive a high-side N-channel FET. The 40 V VDS rating provides comfortable transient headroom above the 12 V nominal (which can spike to 35 V during load-dump per ISO 7637-2), and the 2.4 mOhm RDS(on) keeps conduction loss minimal even at 100+ A continuous loads driving halogen lamps or PTC heaters.

24V Truck/Powertrain Motor Bridge Switch
In 24 V truck and off-highway powertrain systems, the IPB180P04P4L02ATMA2 serves as the high-side switch in an H-bridge driving small DC motors for pumps, fans, and actuators. The 180 A continuous and pulsed current capability handles motor inrush transients, while the AEC-Q101 qualification ensures operation across -40 C to +125 C ambient. Compared to mechanical relays, this MOSFET provides PWM speed control with no audible contact wear and far higher reliability.

Reverse-Battery / Load-Dump Protection
Placed in series with the battery feed, the IPB180P04P4L02ATMA2 acts as a reverse-battery and load-dump protection FET, blocking negative transients and clamping positive load-dump spikes to safe levels. The P-channel topology keeps the body diode reverse-biased during normal operation, so the FET conducts only when the gate is pulled low (system ON). Its 40 V VDS and 150 W PDC rating comfortably absorb the energy in ISO 7637-2 load-dump pulses when properly heatsunk.
Được đề xuất
Server ORing / Hot-Swap Power Switch
In redundant 12 V server power distribution, the IPB180P04P4L02ATMA2 is used as a high-side ORing FET that isolates a failed supply rail from the live bus. The 2.4 mOhm RDS(on) minimizes voltage drop and dissipation, while the 40 V rating covers transients on a 12 V rail. P-channel drive simplicity (gate pulled to GND to turn ON) lets a controller IC manage fast turn-off during reverse-current detection, protecting downstream components.

Industrial 24V Solenoid/Valve Driver
For industrial 24 V solenoid and hydraulic valve control, the IPB180P04P4L02ATMA2 provides a PWM-controllable high-side switch with on-resistance low enough to drive 24 V solenoids at the maximum rated current without external heatsinking in many cases. The D2PAK-7 tab can be screwed directly to a chassis heatsink for high-duty-cycle applications. The -55 C to +175 C junction range supports harsh factory-floor environments.
Được đề xuất
USB PD / High-Current Charging Switch
The IPB180P04P4L02ATMA2 can be used as the high-current load switch in USB-Power-Delivery and proprietary fast-charging adapters, where its low RDS(on) keeps voltage drop across the cable-management FET below 50 mV even at 5 A continuous. The P-channel topology supports low-side current sensing, and the D2PAK-7 footprint handles the elevated power dissipation at 20 V input, 5 A output (P = I^2 x R = 25 x 0.0024 = 0.06 W).

Ghi chú thiết kế
Estimated: at VDS = 0.4 V conduction drop with ID = 100 A continuous, conduction loss is approximately 40 W (P = ID x VDS). With D2PAK-7 theta_JC of approximately 0.5 C/W, junction temperature rise above case is ~20 C, but PCB copper-pour theta_JA can drive overall junction rise to 40-60 C above ambient. Provide at least 1 square inch of 2 oz copper under the tab, or use a screw-attached heatsink for >75 W continuous dissipation. Junction must remain below 175 C at worst case.
Layout for D2PAK-7: place the gate pull-down resistor (typically 10-100 kOhm) close to the gate pin to prevent accidental turn-on from Miller-induced dv/dt. The source pins (2-6) are all internally bonded and serve as the load-current return path; use a wide copper pour connecting them. The tab must be soldered to a copper pour of sufficient area to keep thermal resistance low. Per Infineon's OptiMOS-P2 application note, source-sense kelvin connection is not provided - use source pin closest to gate for gate-drive return.
Critical pitfalls: (1) Do not exceed VGS = +/-20 V absolute max - use a Zener clamp on the gate for inductive-load applications. (2) The body diode is forward-biased from drain-to-source (D2PAK-7 convention for P-channel) and has limited reverse-recovery rating - avoid relying on it for high-frequency switching. (3) High-side P-channel requires the gate driver to swing below the source pin (system voltage), which is 12 V or 24 V below ground - use a gate-drive supply referenced to source, not GND. (4) Verify AEC-Q101 PPAP documentation is current with your build date for safety-critical automotive designs.
