Product details
Overview
IRFR5505TRR from Infineon Technologies (formerly International Rectifier) is a P-channel enhancement-mode HEXFET® Power MOSFET in TO-252AA (D-Pak) surface-mount package, rated for -55 V VDS, 0.11 Ω RDS(on) at VGS = -10 V, and -18 A continuous drain current at TC = 25°C. It features fully avalanche-rated ruggedness, fast switching (tr = 28 ns), and low gate charge (Qg = 32 nC), enabling efficient high-side load switching in DC-DC converters and motor control circuits.
For engineers reviewing the IRFR5505TRR datasheet, IRFR5505TRR pinout, IRFR5505TRR application, or IRFR5505TRR equivalent, key selection criteria include verified P-channel logic-level compatibility, junction-to-case thermal resistance of 2.2°C/W, body diode reverse recovery time (trr = 51–77 ns), and SOA-limited operation under unclamped inductive switching conditions.
Technical Context
This MOSFET employs fifth-generation HEXFET process technology to achieve ultra-low on-resistance per die area while maintaining robust avalanche energy rating (EAS = 150 mJ). Its P-channel topology enables high-side switching without level-shifting circuitry in 12 V and 24 V industrial power rails.
The device integrates a co-packaged body diode with VSD = -1.6 V at IS = -9.6 A and exhibits controlled dv/dt capability (-5.0 V/ns peak diode recovery), supporting reliable commutation in synchronous rectification and H-bridge configurations where shoot-through prevention is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | -55 V - Maximum blocking voltage for high-side switch in 48 V nominal systems with 20% margin |
| RDS(on) | 0.11 Ω @ VGS = -10 V - Enables ≤1.0 W conduction loss at -9.6 A, suitable for thermally constrained PCB layouts |
| ID (continuous) | -18 A @ TC = 25°C - Supports high-current loads such as solenoid drivers and BLDC phase switches |
| Qg | 32 nC - Low gate drive power requirement; compatible with standard 5 V microcontroller GPIOs via buffer |
| tr/tf | 28 ns / 16 ns - Fast edge rates reduce switching losses in PWM frequencies up to 500 kHz |
| EAS | 150 mJ - Withstands single-pulse inductive energy without failure, eliminating need for external snubbers |
| RθJC | 2.2 °C/W - Enables direct heatsinking to copper pour or external metal slug for >40 W dissipation |
Pinout & Package
IRFR5505TRR uses the TO-252AA (D-Pak) surface-mount package with exposed drain pad for thermal and electrical performance. The package supports vapor-phase, infrared, and wave soldering per AN-994 guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Gate) | Control terminal | Receives negative VGS to turn on; requires ≥-10 V for full RDS(on) specification |
| 2 (Drain) | High-side power output | Internally connected to exposed metal tab; must be routed to high-voltage rail and heatsink |
| 3 (Source) | Reference node | Connects to system ground or load return; defines VGS reference for gate drive |
| 4 (Drain) | Redundant drain connection | Parallel path to Pin 2; improves current sharing and thermal spreading across PCB copper |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(on) | 0.11 Ω reduces I²R losses by >35% vs. legacy P-channel MOSFETs at same current density |
| Fully avalanche rated | 150 mJ single-pulse EAS allows safe operation in unclamped inductive switching without derating |
| Fast body diode | trr = 51–77 ns and Qrr = 110–160 nC minimize cross-conduction losses in synchronous rectifiers |
| Surface-mount D-Pak | TO-252AA footprint enables automated assembly and 57 W power dissipation with proper PCB copper area |
| Logic-compatible gate | VGS(th) = -2.0 to -4.0 V ensures turn-on with standard -5 V or -12 V control signals |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRF9540NPBF | Higher RDS(on) (0.2 Ω), TO-220 package, slower switching (tr = 60 ns) | Requires heatsink; unsuitable for high-frequency SMPS or space-constrained PCBs | Preferred for cost-sensitive through-hole designs with ample thermal margin |
| DMG2305UVT-7 | Lower voltage rating (-20 V), smaller SOT-23 package, lower Qg (11 nC) | Limited to 5–12 V logic-level systems; not rated for unclamped inductive switching | Optimal for portable electronics with tight gate drive power budgets and low-voltage rails |
Compared with IRF9540NPBF and DMG2305UVT-7, IRFR5505TRR uniquely balances -55 V rating, 0.11 Ω on-resistance, surface-mount D-Pak thermal performance, and full avalanche ruggedness-making it the only option qualified for 24–48 V industrial motor drives requiring both efficiency and fault tolerance.

FAQ
What is the maximum safe operating temperature for IRFR5505TRR?
The IRFR5505TRR has a specified junction temperature range of -55°C to +150°C. Its maximum continuous case temperature is 150°C, validated by SOA curves in the datasheet. Derating begins above 25°C at 0.45 W/°C, and thermal design must maintain TJ ≤ 150°C under worst-case ambient and power dissipation conditions.
Can IRFR5505TRR be driven directly from a 3.3 V microcontroller GPIO?
No-IRFR5505TRR requires VGS ≤ -10 V for guaranteed RDS(on) = 0.11 Ω. At VGS = -3.3 V, RDS(on) exceeds 0.5 Ω, causing excessive conduction loss. A dedicated gate driver (e.g., TC4427) or level-shifting circuit is required for logic-level control.
Does IRFR5505TRR include an integrated ESD protection diode?
No-IRFR5505TRR does not integrate ESD protection. Its gate oxide is rated for ±20 V absolute maximum VGS, but real-world handling requires external TVS clamping or series resistance to prevent electrostatic damage during PCB assembly or field operation.
Is the body diode in IRFR5505TRR suitable for reverse polarity protection?
Yes-the intrinsic body diode conducts from source to drain (S→D) when VSD > 0, making it usable for reverse polarity protection in low-voltage DC inputs. However, its VSD = -1.6 V at -9.6 A introduces ~1.5 W forward loss, so it is best applied in low-current (<2 A) or intermittent-fault scenarios.
