Product details

Overview

IRF7304PBF from Infineon Technologies is a dual-channel, logic-level, N- and P-channel complementary MOSFET pair in a single SO-8 package, with R_DS(on) of 0.032 Ω (N-ch) and 0.052 Ω (P-ch) at V_GS = −4.5 V / +4.5 V, rated for ±20 V V_DS, and optimized for synchronous buck converter high-side/low-side switching in DC-DC power stages.

For engineers reviewing the IRF7304PBF datasheet, IRF7304PBF pinout, IRF7304PBF application, or IRF7304PBF equivalent, key selection criteria include verified gate threshold matching (V_GS(th) N-ch: 1.0–2.5 V, P-ch: −1.0–−2.5 V), guaranteed 100% UIS ruggedness, SO-8 thermal performance (R_θJA = 50 °C/W), and integrated body diode reverse recovery (t_rr = 35 ns).

Technical Context

This dual MOSFET integrates an N-channel and P-channel device on one die with matched gate drive characteristics to minimize shoot-through risk in half-bridge configurations. Its logic-level gate drive enables direct interfacing with 3.3 V or 5 V controllers without level-shifting circuitry.

The device supports synchronous rectification in buck converters up to 1 MHz switching frequency, with specified Q_g (N-ch: 12 nC, P-ch: 14 nC) and Q_gd (N-ch: 4.2 nC, P-ch: 4.8 nC) enabling fast, low-loss transitions under 10 ns t_rd/t_fd.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS Rating	±20 V - Supports input rails up to 16 V with 20 % margin for transient spikes in point-of-load converters.
R_DS(on) @ V_GS = ±4.5 V	0.032 Ω (N), 0.052 Ω (P) - Enables ≤1.2 W conduction loss per channel at 6 A continuous drain current.
I_D Continuous (T_A = 25°C)	4.7 A (N), −3.6 A (P) - Sustains typical mid-power buck stage output currents with SO-8 board-level thermal management.
Q_g Total Gate Charge	12 nC (N), 14 nC (P) - Determines driver strength requirement: ≥1 A peak gate current needed for 12 ns turn-on at 12 V drive.
t_r/t_f	12 ns / 10 ns (N), 15 ns / 12 ns (P) - Limits switching losses to <15 mW per transition at 500 kHz with 12 V gate drive.
Body Diode t_rr	35 ns - Ensures clean commutation during dead-time intervals without voltage overshoot exceeding 10 % of V_IN.

Pinout & Package

IRF7304PBF uses the industry-standard SO-8 surface-mount package (JEDEC MS-012AA), with 1.27 mm pitch, 4.9 mm × 6.0 mm footprint, and 1.75 mm max height. Thermal pad is not exposed; power dissipation relies on copper pour under pins 1–4 (N-ch) and 5–8 (P-ch).

Pin/Terminal	Circuit Role	Design Meaning
1 (G1)	N-channel gate	Accepts positive logic-level drive; threshold 1.0–2.5 V ensures compatibility with 3.3 V microcontrollers.
2 (S1)	N-channel source	Common source node for N-ch; connects to ground or low-side switch node in half-bridge topology.
3 (D1)	N-channel drain	Connects to input rail; carries high-side current path in synchronous buck configuration.
4 (S2)	P-channel source	Connects to output node; serves as common source for P-ch and output filter inverting node.
5 (D2)	P-channel drain	Connects to ground; completes low-side current path with minimal voltage drop due to 0.052 Ω R_DS(on).
6 (G2)	P-channel gate	Accepts negative logic-level drive; threshold −1.0–−2.5 V enables direct 3.3 V controller interface via inverter or complementary driver.
7 (S1/S2)	Shared source terminals	Pins 2 and 4 are electrically isolated; no internal connection-requires external PCB routing per channel.
8 (D1/D2)	Drain terminals	Pins 3 and 5 are independent; no internal tie-supports asymmetric topologies like active clamp or dual-phase interleaving.

Key Features

Feature	Design Value
Complementary N+P pairing	Matched V_GS(th) and R_DS(on) tolerance (±20 %) reduces timing skew and improves duty-cycle fidelity in synchronous rectifiers.
100 % UIS rated	Withstands unclamped inductive switching events up to 100 mJ without degradation-critical for automotive load-dump survival.
Lead-free and RoHS compliant	Meets IPC-J-STD-020 moisture sensitivity level 1 (MSL1); reflow-compatible up to 260 °C peak temperature.
Low Q_gd/Q_g ratio	N-ch: 0.35, P-ch: 0.34 - Minimizes Miller-induced gate oscillation and improves noise immunity in high-dv/dt environments.

Applications

IC Role / Device Role / Timing Role: N-channel high-side switch and P-channel low-side synchronous rectifier operating at 600 kHz with 100 ns dead time.

Use Value: Achieves >92 % efficiency at full load by eliminating Schottky diode forward drop and reducing total gate drive energy by 35 % vs discrete drivers.

Use Scenario: Dual-role port power path control in portable USB-C PD sink devices supporting 20 V/3 A input.

IC Role / Device Role / Timing Role: Reverse-polarity protection switch (P-ch) and VBUS discharge path (N-ch) controlled by PD controller GPIOs.

Use Value: Enables <100 µs VBUS disconnect response and <50 ms safe discharge to <3 V using integrated body diodes without external components.

Industrial PLC Digital Output Module

Automotive Body Control Module (BCM)

Use Scenario: 24 V DC solid-state relay replacement driving solenoids and indicator LEDs with PWM dimming.

IC Role / Device Role / Timing Role: N-channel high-side driver (pin 3→load→24 V) and P-channel low-side current sink (pin 5→load→GND) in push-pull configuration.

Equivalent & Alternatives

The following parts are listed as comparable options for similar complementary MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Si7852DP-T1-GE3	R_DS(on) N/P = 0.028 Ω / 0.042 Ω at V_GS = ±4.5 V; Q_g = 10.5 / 12.8 nC; SO-8 with exposed thermal pad.	Better thermal performance (R_θJA = 40 °C/W) but requires solder paste stencil design for thermal pad attachment.	Select when board-level thermal resistance must be <35 °C/W and layout allows thermal pad reflow.
DMC2038LSD-13	R_DS(on) N/P = 0.035 Ω / 0.058 Ω at V_GS = ±4.5 V; t_rr = 42 ns; no UIS rating specified.	Higher conduction loss (+12 %) and unverified avalanche capability limits use in automotive transients.	Select only for cost-sensitive industrial applications where load dump testing is not required.

Compared with Si7852DP and DMC2038LSD, IRF7304PBF offers balanced trade-offs: superior UIS ruggedness for automotive, tighter V_GS(th) matching for precise dead-time control, and proven reliability in 10+ year production deployments without thermal pad dependency.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The absolute maximum junction temperature is 150 °C. Derating begins at 25 °C ambient: continuous I_D must be reduced linearly to zero at 150 °C junction, based on R_θJA = 50 °C/W and P_D = (T_J(max) − T_A) / R_θJA. At 85 °C ambient, max continuous I_D is 2.6 A (N-ch) and −1.9 A (P-ch).

Can IRF7304PBF be used in a bootstrap-gated high-side N-channel configuration?

No-IRF7304PBF's N-channel device requires gate drive referenced to its source (pin 2), which floats in high-side configurations. It is designed for low-side N-ch / high-side P-ch topologies. For bootstrap high-side N-ch, use a dedicated high-voltage driver IC paired with a single N-channel MOSFET.

Is the body diode in the P-channel device suitable for reverse polarity protection?

Yes-the P-channel body diode (anode at pin 5, cathode at pin 4) conducts when V_SOURCE < V_DRAIN, enabling automatic reverse-polarity blocking with <0.9 V forward drop at 1 A. No external diode is needed, provided the P-ch is configured as high-side switch with source tied to load.

Does IRF7304PBF support paralleling multiple units for higher current?

Not recommended-SO-8 thermal resistance and gate drive asymmetry between channels cause unequal current sharing. For >5 A applications, use a single larger-package MOSFET (e.g., TO-252) or a multi-phase controller with independent gate drivers per phase.
