Product details
Overview
IRF9388PBF from Infineon Technologies is a P-channel enhancement-mode MOSFET in SO-8 package, rated for -30 V VDS, 11.9 mΩ RDS(on) at -10 V VGS, -12 A continuous drain current at 25°C, and optimized for notebook PC adapter input switching with direct gate drive capability.
For engineers reviewing the IRF9388PBF datasheet, IRF9388PBF pinout, IRF9388PBF application, or IRF9388PBF equivalent, this device supports high-efficiency synchronous rectification, load switching, and DC-DC converter high-side control where low gate threshold and robust avalanche energy (120 mJ) are critical.
Technical Context
This MOSFET features a gate threshold voltage of -1.3 to -2.4 V, enabling reliable turn-on with standard logic-level drivers; its 8.5 mΩ typical RDS(on) at -20 V VGS and 20 S forward transconductance support high-current, low-conduction-loss operation in compact power stages.
Thermal performance is defined by 50 °C/W RθJA on 1-inch² copper board and 20 °C/W RθJL; body diode characteristics include -1.2 V VSD at -2.5 A and 51–76 ns trr, supporting moderate-frequency freewheeling in buck and flyback topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | -30 V - Maximum blocking voltage for 24 V rail input switching |
| RDS(on) max @ -10 V | 11.9 mΩ - Conduction loss ≤ 1.7 W at -12 A, enabling thermally constrained PCB layouts |
| ID continuous @ 25°C | -12 A - Supports >60 W adapter primary-side switching without forced air |
| VGS(th) | -1.3 to -2.4 V - Ensures full enhancement with 3.3 V or 5 V gate drivers |
| EAS | 120 mJ - Withstands single-pulse inductive energy in unregulated input stages |
| Ciss | 1680 pF - Gate drive requirement ~35 nC total charge, compatible with low-power controllers |
| Qg @ -10 V | 35–52 nC - Enables <100 ns switching transitions at 500 kHz with 1 Ω driver |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si7157DP-T1-GE3 | RDS(on) = 10.5 mΩ @ -10 V, but lower ID (-9.5 A) and no specified EAS | Limited to ≤45 W adapters; unsuitable for high-energy avalanche conditions | Prefer when gate drive is fixed at -10 V and thermal margin exceeds 15°C |
| DMG2305UVT-7 | RDS(on) = 42 mΩ @ -4.5 V, higher threshold (-0.9 V min), smaller TSOP-6 package | Requires dedicated -5 V gate bias; not suitable for direct 3.3 V logic drive | Select only if board space is constrained and peak current ≤3 A |
Compared with Si7157DP-T1-GE3 and DMG2305UVT-7, IRF9388PBF delivers superior avalanche ruggedness and higher continuous current in a standardized SO-8, making it optimal for 60–90 W adapter input stages where reliability under transient overload is mandatory.

FAQ
What is the maximum safe operating temperature for IRF9388PBF?
The IRF9388PBF has a maximum junction temperature of +150°C and a storage temperature range of -55°C to +150°C. Its RθJA is 50°C/W on a 1-inch² copper board, so at 12 A and 11.9 mΩ, junction rise is ~8.6°C above ambient-well within limits at ≤140°C ambient with minimal heatsinking.
Can IRF9388PBF be driven directly from a 3.3 V microcontroller GPIO?
Yes. With a typical VGS(th) of -1.8 V and guaranteed -1.3 V minimum, the IRF9388PBF fully enhances at -3.3 V gate drive. At that voltage, RDS(on) rises to ~25 mΩ, yielding ~3.6 W conduction loss at -12 A-acceptable for intermittent or derated operation.
Does IRF9388PBF include an integrated Schottky diode?
No. It uses a monolithic P-channel silicon MOSFET structure with an inherent body (p-n junction) diode. That diode has VSD = -1.2 V at -2.5 A and trr = 51–76 ns-suitable for moderate-frequency freewheeling but not ultra-fast synchronous rectification.
Is IRF9388PBF suitable for automotive applications?
No. It is qualified to Consumer grade per JEDEC JESD47F, not AEC-Q101. Its SO-8 package lacks automotive-grade bond wire construction and extended temperature validation; use Infineon's AUIRF9388 for automotive-grade equivalents.
