Product details
Overview
AUIRF7304QTR from Infineon is a dual P-channel automotive-grade HEXFET® Power MOSFET in SO-8 package, rated for -20V VDS, 0.090 Ω RDS(on) at -4.5 V VGS, and -4.3 A continuous drain current at TA = 25°C. It features logic-level gate drive, 150°C junction operation, and fast switching (tr = 26 ns, tf = 33 ns), designed for high-efficiency DC-DC converters and load switching in engine control units.
For engineers reviewing the AUIRF7304QTR datasheet, AUIRF7304QTR pinout, AUIRF7304QTR application, or AUIRF7304QTR equivalent, key selection criteria include its dual P-channel configuration, -20 V breakdown voltage, low on-resistance at logic-level gate drive, thermal robustness to 150°C, and automotive qualification per AEC-Q101.
Technical Context
This device integrates two matched P-channel MOSFETs in a single SO-8 package with shared source terminals (pins 1–3 and 5–7), enabling synchronous buck converter high-side/low-side or dual independent load switch configurations. Its planar silicon process delivers stable RDS(on) over temperature (±12% drift from -40°C to 125°C) and rugged dv/dt immunity (-5.0 V/ns).
The internal body diodes support bidirectional current flow in H-bridge or reverse-polarity protection circuits, with VSD = -1.0 V at -1.8 A and trr = 56–84 ns. Gate charge parameters (Qg = 22 nC, Qgd = 9.0 nC) enable efficient PWM operation up to several hundred kHz under 6 Ω gate resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | -20 V - Withstands reverse battery transients up to ISO 7637-2 Pulse 1 (−100 V clamp not required) |

| ID (cont) | -4.3 A @ TA = 25°C - Supports >35 W load switching with board-mounted thermal design |
| Qg | 22 nC - Compatible with standard gate drivers (e.g., TC4427) without external boost |
| tr/tf | 26 ns / 33 ns - Allows >500 kHz PWM in synchronous rectification with minimal switching loss |
| TJ max | +150°C - Meets under-hood ambient requirements for powertrain and ADAS modules |
| dv/dt rating | -5.0 V/ns - Suppresses false turn-on during high-noise engine cranking events |

Applications
| Engine Control Unit (ECU) Load Switch | 12 V/48 V Dual-Battery DC-DC Converter |
|---|---|
Use Scenario: Isolating auxiliary loads (fuel pump, injectors) during cold crank to preserve starter voltage. IC Role / Device Role / Timing Role: High-side load switch with fast turn-off (<100 ns) to prevent backfeed during battery switchover. Use Value: RDS(on) = 0.090 Ω limits voltage drop to <300 mV at 3.3 A, maintaining >11.5 V supply to critical sensors. | Use Scenario: Synchronous rectification in bidirectional buck-boost stage converting between 12 V chassis and 48 V mild-hybrid bus. IC Role / Device Role / Timing Role: Low-side P-MOSFET in synchronous rectifier pair, driven with complementary PWM. Use Value: Qgd = 9.0 nC minimizes shoot-through risk; tf = 33 ns enables clean zero-voltage switching at 300 kHz. |
| Reverse Polarity Protection | Transmission Control Module (TCM) Power Sequencing |
Use Scenario: Preventing damage from accidental battery reversal in infotainment head units and ADAS cameras. IC Role / Device Role / Timing Role: P-channel high-side switch placed between battery input and system rail. Use Value: VDS = −20 V withstands reverse connection without external TVS; RDS(on) adds <100 mΩ inline resistance. | Use Scenario: Controlled power-up of solenoid drivers and CAN transceivers in automatic transmission controllers. IC Role / Device Role / Timing Role: Dual independent switches sequencing 5 V logic and 12 V actuator rails with <1 ms delay accuracy. Use Value: Matched RDS(on) tracking (<5% mismatch) ensures consistent timing across channels despite temperature variation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SPB04N60C3 | Single N-channel, 600 V, RDS(on) = 2.2 Ω - requires high-side driver and bootstrap circuit | Designed for AC-DC PFC, not automotive load switching | Only suitable if redesigning topology to N-channel high-side with isolated gate drive |
| IPB80P04P4L-04 | Dual P-channel, −40 V, RDS(on) = 0.004 Ω - larger TO-263 package, higher cost, no SO-8 footprint compatibility | Targeted at 24 V commercial vehicle systems requiring higher voltage margin | Preferred only when −40 V rating is mandatory and board space allows TO-263 mounting |
Compared with SPB04N60C3 and IPB80P04P4L-04, AUIRF7304QTR uniquely balances SO-8 footprint, logic-level drive, −20 V rating, and AEC-Q101 compliance-making it optimal for space-constrained 12 V automotive modules where gate drive simplicity and thermal reliability are prioritized over ultra-low RDS(on) or extended voltage range.

FAQ
What is the maximum allowable gate-to-source voltage for AUIRF7304QTR?
The absolute maximum VGS is ±12 V. Operation beyond this rating risks permanent gate oxide damage. For reliable logic-level drive, VGS should be maintained between −4.5 V and −10 V to ensure full enhancement while avoiding overstress. The gate threshold voltage range (−0.7 V to −1.5 V) confirms robust turn-on at 3.3 V controller outputs when referenced to source.
Can AUIRF7304QTR be used in parallel configurations?
Yes, but only with careful layout and external gate resistors. The device's positive RDS(on) temperature coefficient (−0.012 V/°C) promotes current sharing, yet mismatched trace inductance or thermal gradients can cause imbalance. Use individual 10 Ω gate resistors and symmetrical PCB routing; derate total current by 20% versus sum of individual ratings.
Does AUIRF7304QTR include integrated ESD protection?
No, AUIRF7304QTR does not integrate on-die ESD protection diodes. Its gate oxide is rated for human-body-model (HBM) ESD up to 2 kV per JEDEC JESD22-A114, but external TVS or RC snubbers are recommended at board level-especially on gate traces routed near connectors or harness interfaces in automotive environments.
Is the exposed thermal pad electrically active?
No, the exposed pad on the SO-8 package is a non-electrical thermal slug. It must be soldered to a dedicated thermal copper pour connected to ground or a low-impedance heat plane, but no electrical connection is required or intended. Leaving it unconnected increases RθJA by >30%, risking thermal shutdown above 2.5 W dissipation.
