Product details
Overview
AUIRFR2905ZTR from International Rectifier is an Automotive P-channel HEXFET MOSFET supplied in the TO-252-3, DPAK (2 Leads + Tab), SC-63 package. The device is used as a p-channel. switching element where drain-source voltage rating, conduction loss, gate charge, avalanche behavior, and package thermal resistance must be matched to the circuit.
For engineers reviewing the AUIRFR2905ZTR datasheet, AUIRFR2905ZTR pinout, AUIRFR2905ZTR application, or AUIRFR2905ZTR equivalent, this device is commonly used in power load switching, dc-dc converter stages, motor and inductive load control, and repair and bom continuity designs. For engineers comparing AUIRFR2905ZTR against other MOSFETs, the useful checks are voltage rating: −55 V class. The bulk supply entry and package style should be confirmed before using it as a direct BOM replacement.
Technical Context
In a switching circuit, AUIRFR2905ZTR may serve as a low-side switch, high-side device, synchronous rectifier, motor-control transistor, battery-path switch, or converter power device depending on polarity and topology. The package tab or exposed pad normally carries the drain connection and dominates the thermal path.
DPAK / TO-252 surface-mount package for medium-current switching with PCB copper thermal spreading. Gate-drive selection should account for total gate charge, Miller plateau behavior, switching frequency, and allowable VGS range; using only RDS(on) to compare MOSFETs can lead to excessive switching loss or poor transient behavior.
Thermal validation is required at the final load current because rated current values assume defined case or board conditions. For inductive loads, the avalanche rating, body-diode recovery, clamp network, and safe operating area should be checked with the actual load profile.

Equivalent & Alternatives
When evaluating AUIRFR2905ZTR equivalent devices, engineers should compare only specific orderable alternatives and should verify package footprint, pinout, electrical ratings, thermal data, qualification status, and suffix or packing requirements before substitution.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AUIRFR2905Z | Same base family or close suffix variant; electrical function may be similar, while package, reel orientation, lead finish, or orderable code can differ. | Used when the existing design needs the same functional device with a different supply or assembly code. | Compare AUIRFR2905Z against AUIRFR2905ZTR for package drawing, suffix meaning, tape orientation, and documentation revision. |
| AUIRF9952QTR | Related International Rectifier / Infineon orderable device; electrical ratings, package, and protection behavior may differ. | Used as a possible functional alternative in redesigned or revalidated circuits. | Use only after comparing AUIRF9952QTR and AUIRFR2905ZTR electrical ratings, package, pinout, and thermal behavior; do not assume drop-in compatibility. |
| IRF6802SDTRPBF | Related International Rectifier / Infineon orderable device; electrical ratings, package, and protection behavior may differ. | Used as a possible functional alternative in redesigned or revalidated circuits. | Use only after comparing IRF6802SDTRPBF and AUIRFR2905ZTR electrical ratings, package, pinout, and thermal behavior; do not assume drop-in compatibility. |
