Product details
Overview
IRF7322D1TRPBF from Infineon Technologies (formerly International Rectifier) is a co-packaged P-channel HEXFET® Power MOSFET and low-VF Schottky diode in a single SO-8 package, designed for synchronous buck regulator high-side switching. It delivers RDS(on) = 49 mΩ @ VGS = −4.5 V, Schottky VF = 0.39 V @ IF = 1.0 A, TJ = 125°C, and supports −5.3 A continuous drain current at 25°C. Used in portable DC-DC converters where board space and efficiency are critical.
For engineers reviewing the IRF7322D1TRPBF datasheet, IRF7322D1TRPBF pinout, IRF7322D1TRPBF application, or IRF7322D1TRPBF equivalent, key selection criteria include verified co-packaged MOSFET/diode integration, SO-8 thermal performance (RθJA = 62.5°C/W), gate threshold voltage (−0.70 V), body diode recovery time (47–71 ns), and Generation 5 HEXFET low on-resistance architecture.
Technical Context
This FETKY device integrates a logic-level P-channel MOSFET and a Schottky rectifier sharing common source and drain terminals - enabling synchronous rectification without external diode placement. The MOSFET features enhanced channel geometry for low RDS(on) per die area, while the Schottky diode provides fast recovery (trr ≤ 71 ns) and low forward drop (VF ≤ 0.57 V @ 2.0 A, 125°C).
Thermal design leverages a modified SO-8 leadframe with improved heat spreading; junction-to-ambient resistance is 62.5°C/W on FR-4. The device operates across −55°C to +150°C, supports ±12 V gate drive, and exhibits controlled dv/dt (−5.0 V/ns) during diode recovery to minimize EMI in high-frequency switching.

Equivalent & Alternatives
The following parts are listed as comparable options for similar co-packaged MOSFET/Schottky applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si7842DP-T1-GE3 | RDS(on) = 52 mΩ @ −4.5 V; Schottky VF = 0.45 V @ 1 A; SO-8 footprint identical | Higher conduction loss in high-duty-cycle apps; slightly slower trr (85 ns) | Prefer when sourcing from Vishay's long-term supply program over Infineon's discontinuation risk |
| DMN3025LSD-13 | P-channel only; no integrated Schottky; requires external diode; RDS(on) = 25 mΩ @ −4.5 V | Lower RDS(on) but increases component count and layout complexity | Select when peak efficiency > board-area savings, and thermal margin allows discrete diode placement |
Compared with Si7842DP-T1-GE3 and DMN3025LSD-13, IRF7322D1TRPBF uniquely balances integrated functionality, thermal robustness, and logic-level drive - making it optimal for space-constrained, medium-power synchronous buck stages where reliability and layout simplicity are prioritized over marginal RDS(on) gains.

FAQ
What is the maximum safe operating frequency for IRF7322D1TRPBF in a synchronous buck converter?
IRF7322D1TRPBF supports switching frequencies up to 2 MHz in well-designed layouts. Its 19 nC total gate charge and 71 ns reverse recovery time allow stable operation at 1–2 MHz with appropriate gate drive strength (≥1 A peak) and minimized parasitic inductance. Efficiency peaks near 1 MHz for typical 5–12 V input applications.
Can IRF7322D1TRPBF be used in linear regulator configurations?
No - IRF7322D1TRPBF is not rated for linear-mode operation. Its Safe Operating Area (SOA) curve shows operation is limited to pulse widths ≤10 ms at full current, and continuous linear use would exceed its 2.0 W power dissipation limit at 25°C ambient. It is intended exclusively for switching applications.
How does the integrated Schottky diode affect PCB layout versus using a discrete diode?
The integrated Schottky eliminates two solder joints, reduces loop inductance by ~30%, and removes the need for separate thermal pad routing. Layout simplifies to a single SO-8 footprint with shared source/drain copper pours - cutting layout time by ~40% and improving EMI performance due to minimized high-di/dt paths.
Is IRF7322D1TRPBF compliant with RoHS and REACH regulations?
Yes - IRF7322D1TRPBF is lead-free (PbF) and fully compliant with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The "PbF" suffix in the part number explicitly denotes lead-free construction, and the device carries the required compliance markings per JEDEC standards.
