Product details
Overview
IRFR2905ZTRR from Infineon Technologies (formerly International Rectifier) is an N-channel enhancement-mode automotive-grade HEXFET® Power MOSFET in D-Pak (TO-252) package, rated for 55 V VDSS, 14.5 mΩ RDS(on) at VGS = 10 V, and 42 A continuous drain current at TC = 25°C. It features 175°C maximum junction temperature, fast switching (tr = 66 ns, tf = 35 ns), and rated repetitive avalanche capability - deployed in engine control modules, DC-DC converters, and motor drive stages.
For engineers reviewing the IRFR2905ZTRR datasheet, IRFR2905ZTRR pinout, IRFR2905ZTRR application, or IRFR2905ZTRR equivalent, key selection criteria include its low RDS(on) at 10 V gate drive, robust 175°C thermal rating, body diode recovery performance (trr = 23–35 ns), and automotive qualification per AEC-Q101.
Technical Context
This MOSFET uses advanced planar silicon processing to achieve ultra-low on-resistance per die area while maintaining high avalanche ruggedness. Its gate threshold voltage (2.0–4.0 V) supports standard 5 V and 10 V logic-level drive, and its 1.38 °C/W junction-to-case thermal resistance enables high-power operation with minimal heatsinking.
The device integrates a fast, low-VSD (≤1.3 V) body diode with Qrr = 16–24 nC and trr = 23–35 ns under specified conditions (IF = 36 A, dI/dt = 100 A/µs). Its safe operating area (SOA) is defined up to 100 µs single-pulse, limited by RDS(on) at high VDS.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 55 V - Maximum drain-source blocking voltage before avalanche onset; suitable for 48 V automotive systems and 24 V industrial rails. |
| RDS(on) @ VGS = 10 V | 14.5 mΩ max - Enables ≤0.6 W conduction loss at 42 A, reducing thermal load in high-current switching nodes. |
| ID @ TC = 25°C | 42 A - Continuous drain current rating with PCB-mount heatsinking; derates linearly above 25°C case temperature. |
| tr/tf | 66 ns / 35 ns - Fast edge rates support >100 kHz PWM operation with minimized switching losses in buck and half-bridge topologies. |
| TJ max | 175°C - Extended junction temperature rating allows operation in under-hood environments without forced cooling. |
| EAS | 59 mJ - Single-pulse avalanche energy rating confirms ruggedness against inductive turn-off transients in motor and solenoid drives. |
| Qg | 44 nC max - Gate charge determines driver strength requirement; compatible with standard gate drivers (e.g., IR2104, UCC27531). |
Pinout & Package
IRFR2905ZTRR is housed in a surface-mount D-Pak (TO-252) package with exposed drain pad for thermal and electrical connection. The package has three terminals: Drain (D), Source (S), and Gate (G), with Drain electrically connected to the tab.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main power output terminal | Electrically tied to copper tab; must be soldered to large PCB copper pour for thermal dissipation and low-inductance return path. |
| Source | Reference node for gate drive and current sensing | Serves as common return for load current and gate driver ground; low-inductance layout critical for stable switching. |
| Gate | Control input for channel conduction | High-impedance MOS gate requiring controlled slew rate; susceptible to ringing if not properly terminated with series resistor (typically 5–22 Ω). |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q101 qualified - Validated for temperature cycling, humidity, and mechanical stress in automotive under-hood applications. |
| Repetitive avalanche rating | Rated for repeated unclamped inductive switching events up to TJmax - Eliminates need for external snubbers in relay/motor drive circuits. |
| Ultra-low RDS(on) | 11.1 mΩ typical at VGS = 10 V - Reduces I²R losses by >30% vs. legacy 55 V MOSFETs, improving efficiency in 12–48 V DC-DC stages. |
| Fast body diode | trr = 23–35 ns, Qrr = 16–24 nC - Minimizes reverse recovery loss and EMI in synchronous rectification and freewheeling paths. |
| Thermal robustness | RθJC = 1.38 °C/W - Enables >40 W power dissipation with modest heatsinking, supporting compact high-current designs. |
Applications
| Engine Control Unit (ECU) Fuel Injector Driver | 48 V Automotive DC-DC Converter Primary Switch |
|---|---|
Use Scenario: High-speed, high-current switching of fuel injectors in gasoline direct injection systems with peak currents up to 36 A. IC Role / Device Role / Timing Role: Low-side power switch controlling injector coil energization/de-energization; operates at 10–20 Hz with precise pulse-width control. Use Value: 14.5 mΩ RDS(on) minimizes coil heating during dwell time; 175°C rating ensures reliability in hot ECU enclosures near the engine block. |
Use Scenario: Primary-side synchronous rectifier in isolated 48 V-to-12 V bidirectional DC-DC converter for mild hybrid vehicles. IC Role / Device Role / Timing Role: High-frequency (100–300 kHz) hard-switched N-channel switch in phase-shifted full-bridge topology. Use Value: Fast tr/tf and low Qg reduce switching loss; body diode trr < 35 ns prevents shoot-through during dead-time transitions. |
| Electric Power Steering (EPS) Motor Phase Leg | Industrial 24 V BLDC Motor Inverter Stage |
Use Scenario: Half-bridge leg in 3-phase inverter driving brushless motor in EPS system, handling 30–40 A RMS phase current. IC Role / Device Role / Timing Role: High-side and low-side switching element in H-bridge configuration; requires robust avalanche capability during regenerative braking. Use Value: Rated repetitive avalanche energy (EAR) supports safe energy absorption during motor back-EMF spikes without external clamping. |
Use Scenario: Output stage in compact 24 V BLDC motor controller for automated guided vehicles (AGVs) and factory robotics. IC Role / Device Role / Timing Role: Low-side switch in 3-phase inverter; driven by isolated gate driver with 10 V gate voltage. Use Value: 42 A continuous current rating at TC = 25°C enables 100% duty-cycle operation with minimal heatsink; D-Pak footprint simplifies automated assembly. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL100N5LF6AG | 60 V VDSS, 9.5 mΩ RDS(on), 100 A ID, PowerFLAT 5x6 package, no AEC-Q101 certification | Higher current capacity but lacks automotive qualification; requires larger PCB area and different thermal interface | Preferred for non-automotive 48 V systems where higher current headroom and lower RDS(on) outweigh qualification needs. |
| ON Semiconductor NTMFS5C673NL | 60 V VDSS, 10.5 mΩ RDS(on), 52 A ID, SO-8FL package, AEC-Q101 qualified | Smaller footprint and lower gate charge (34 nC), but lower avalanche rating (EAS = 32 mJ) and 150°C TJmax | Best for space-constrained automotive modules needing faster switching and smaller layout, where avalanche stress is mitigated by circuit design. |
Compared with STL100N5LF6AG and NTMFS5C673NL, IRFR2905ZTRR offers the highest junction temperature rating (175°C) and verified repetitive avalanche capability - making it uniquely suited for thermally aggressive, inductive-load automotive applications where transient robustness is non-negotiable.

FAQ
Is IRFR2905ZTRR pin-compatible with IRFR2905PBF?
Yes - both share identical D-Pak (TO-252) package outline, pin assignment (Drain-Tab, Source, Gate), and mechanical footprint. IRFR2905ZTRR is the tape-and-reel version of IRFR2905PBF; electrical specifications and thermal characteristics are identical per datasheet Rev. D.
What is the maximum recommended gate drive voltage?
The absolute maximum gate-to-source voltage is ±20 V, but the device is characterized and optimized for 10 V drive. Operating at 12–15 V provides margin for RDS(on) reduction without significant increase in Qg or risk of gate oxide stress under transient conditions.
Does IRFR2905ZTRR require a gate resistor for stability?
Yes - a series gate resistor (5–22 Ω) is required to dampen parasitic oscillation caused by gate-drain capacitance (Crss = 120 pF) and PCB trace inductance. Without it, ringing can exceed VGS limits and cause erratic switching or device failure.
Can IRFR2905ZTRR replace IRFZ44N in automotive designs?
No - IRFZ44N is not AEC-Q101 qualified, has higher RDS(on) (17.5 mΩ), lower TJmax (175°C vs. 175°C same, but IRFZ44N lacks automotive test validation), and inferior avalanche rating. IRFR2905ZTRR meets automotive reliability requirements that IRFZ44N does not satisfy.
