Product details

Overview

IRFR1010ZTRPBF from Infineon Technologies is a 55V, 42A N-channel DPAK-packaged Power MOSFET with 7.5mΩ R_DS(on) at V_GS = 10V, 175°C maximum junction temperature, and rated for repetitive avalanche operation. It serves as a high-efficiency main or synchronous rectifier switch in DC-DC converters, motor drives, and power supplies.

For engineers reviewing the IRFR1010ZTRPBF datasheet, IRFR1010ZTRPBF pinout, IRFR1010ZTRPBF application, or IRFR1010ZTRPBF equivalent, key selection criteria include its low conduction loss (5.8–7.5mΩ), fast switching (t_d(on) = 17ns, t_f = 48ns), body diode recovery (t_rr = 24–36ns), and thermal robustness (R_θJC = 1.11°C/W).

Technical Context

This MOSFET employs advanced HEXFET® silicon processing to minimize on-resistance per die area while maintaining ruggedness. Its gate charge profile (Q_g = 63–95nC, Q_gd = 23nC) supports efficient hard-switching in buck and half-bridge topologies up to several hundred kHz.

The integrated body diode exhibits low forward voltage (V_SD ≤ 1.3V at 42A) and controlled reverse recovery (Q_rr = 20–30nC), enabling reliable operation in synchronous rectification and freewheeling roles without external Schottky supplementation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	55V - Maximum blocking voltage before avalanche; defines safe operating range in 48V bus systems.
R_DS(on)	5.8–7.5mΩ @ V_GS = 10V - Directly determines I²R conduction loss; enables <1.3W loss at 42A continuous.
I_D	42A @ T_C = 25°C - Continuous current rating under ideal heatsinking; derates to ~25A at T_C = 100°C.
E_AS	91mJ (tested) - Single-pulse avalanche energy capability; allows unclamped inductive turn-off without failure.
t_r/t_f	76ns/48ns - Rise/fall times at V_DD = 28V, I_D = 42A, R_G = 7.6Ω; sets minimum practical switching period.
R_θJC	1.11°C/W - Junction-to-case thermal resistance; enables direct mounting to heatsink with predictable ΔT_J.
Q_g	63–95nC - Total gate charge; determines driver current requirement (e.g., 1A peak for 100ns turn-on).

Pinout & Package

IRFR1010ZTRPBF is housed in a surface-mount DPAK (TO-252AA) package with three terminals: Drain (tab), Source (pin 2), and Gate (pin 1). The exposed drain pad provides low-inductance, high-current path and primary thermal conduction path to PCB copper.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main current sink / high-side switch node	Electrically and thermally connected to PCB copper pour; requires solder mask opening and thermal vias.
Source (Pin 2)	Reference node for gate drive and current sensing	Low-inductance return path; critical for stable gate control and accurate R_DS(on)-based current monitoring.
Gate (Pin 1)	Control input for channel modulation	High-impedance input requiring <100nC charge to fully enhance; sensitive to ringing due to L_S = 7.5nH.

Key Features

Feature	Design Value
Ultra-low R_DS(on)	5.8mΩ typical enables >96% efficiency in 12V→5V 20A buck converters at full load.
175°C rated junction	Allows sustained operation in sealed enclosures or high-ambient industrial environments without derating.
Repetitive avalanche rated	Validated for repeated unclamped inductive switching (e.g., relay coil snubbing, solenoid drivers).
Fast body diode recovery	t_rr = 24ns ensures minimal shoot-through risk in synchronous rectifiers operating above 200kHz.
Lead-free and RoHS compliant	Meets IPC-J-STD-020D reflow profile; compatible with standard Pb-free assembly processes.

IC Role / Device Role: Main switch in LLC resonant half-bridge secondary synchronous rectification stage.

Use Value: Low Q_gd/Q_g ratio (23/63nC) minimizes Miller-induced false turn-on during high dv/dt transitions.

Use Scenario: Dimmable constant-current LED driver for architectural lighting (10–50V, 3–7A strings).

IC Role / Device Role: PWM-controlled current shunt switch regulating average LED current.

Use Value: Fast t_f (48ns) and low C_oss (470pF) enable clean 1–10kHz dimming waveforms with <1% current ripple.

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	R_DS(on) = 4.5mΩ @ 10V, but only rated to 150°C junction; higher Q_g (110nC).	Better conduction loss at low T_J, but less suitable for sustained high-temp operation.	Prefer when ambient <85°C and peak efficiency >97% is required; avoid in sealed enclosures.
ON Semiconductor NTMFS5C673NL	R_DS(on) = 6.7mΩ @ 10V, 175°C rated, but DFN5x6 package limits thermal mass and heatsinking flexibility.	Higher power density but lower transient thermal capacity than DPAK.	Choose for space-constrained designs where PCB area is premium and airflow is guaranteed.

Compared with STL100N5LF6AG and NTMFS5C673NL, IRFR1010ZTRPBF offers the best balance of ruggedness (175°C + repetitive avalanche), thermal interface simplicity (DPAK tab), and gate drive compatibility (moderate Q_g), making it optimal for industrial-grade power stages where reliability trumps marginal efficiency gains.

FAQ

What is the maximum continuous drain current at 100°C case temperature?

The IRFR1010ZTRPBF supports 25A continuous drain current at T_C = 100°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the DPAK package and must be verified against actual board layout and heatsinking in the target application.

Does this MOSFET require a gate resistor for stability?

Yes - a series gate resistor (typically 5–15Ω) is recommended to dampen parasitic oscillation caused by gate-source inductance (L_S = 7.5nH) and Miller capacitance (C_rss = 250pF), especially when driven by high-speed controllers or in high-dv/dt environments.

Can IRFR1010ZTRPBF replace IRFR1010PBF in existing designs?

Yes - IRFR1010ZTRPBF is the lead-free, RoHS-compliant successor to IRFR1010PBF, sharing identical electrical specifications, pinout, and package. No layout or firmware changes are needed, though reflow profile must comply with J-STD-020D for Pb-free soldering.

Is the body diode suitable for reverse recovery in synchronous rectification?

Yes - the integral body diode has t_rr = 24–36ns and Q_rr = 20–30nC, enabling reliable synchronous rectification up to 300kHz in buck converters. However, zero-voltage switching (ZVS) or adaptive dead-time control is advised to minimize commutation loss.
