Product details

Overview

IRFR3707ZTRRPBF from Infineon Technologies (formerly International Rectifier) is an N-channel enhancement-mode power MOSFET in D-Pak (TO-252) package, rated for 60 V V_DS, 48 A I_D (T_C = 100°C), and 11.5 mΩ R_DS(on) @ V_GS = 10 V. It serves as a main switch in DC-DC converters, motor drive half-bridges, and load switching circuits.

For engineers reviewing the IRFR3707ZTRRPBF datasheet, IRFR3707ZTRRPBF pinout, IRFR3707ZTRRPBF application, or IRFR3707ZTRRPBF equivalent, key selection criteria include its low R_DS(on) at 10 V gate drive, fast turn-on/turn-off times (t_on = 22 ns, t_off = 32 ns), thermal resistance (R_θJC = 1.4°C/W), and D-Pak surface-mount compatibility for high-current PCB layouts.

Technical Context

This Generation 3 HEXFET device uses planar stripe cell structure with optimized gate oxide thickness and source/drain doping profiles to achieve low conduction loss while maintaining rugged avalanche capability (E_AS = 190 mJ). Its threshold voltage (V_GS(th)) ranges from 2.0 V to 4.0 V, enabling reliable turn-on with standard 5 V logic-level gate drivers.

The MOSFET features integrated body diode with soft recovery characteristics (Q_rr = 55 nC, t_rr = 55 ns), reducing switching losses in synchronous rectification and freewheeling applications. Its SOA is defined up to 100°C case temperature with pulse width-limited safe operating area curves.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - Maximum drain-to-source blocking voltage for 24 V and 48 V bus systems
R_DS(on) @ V_GS = 10 V	11.5 mΩ - Enables ≤0.5 W conduction loss at 6.6 A RMS in continuous conduction mode
I_D (T_C = 100°C)	48 A - Sustains high pulsed current in motor phase legs without derating below 100°C case temp
Q_g	35 nC - Gate charge supports <100 kHz PWM switching with <1 W gate driver dissipation
E_AS	190 mJ - Withstands single-pulse inductive energy without failure in unclamped inductive switching
R_θJC	1.4°C/W - Allows direct heatsinking to PCB copper pour or external heatsink for thermal management

Pinout & Package

Package: D-Pak (TO-252), surface-mount, single-ended leadframe with exposed drain pad for thermal and electrical connection.

Pin 3 (Drain)	Power output	High-current path to load/bus; electrically and thermally tied to exposed metal pad

Key Features

Feature	Design Value
Ultra-low R_DS(on) at 10 V	11.5 mΩ enables high-efficiency operation in 48 V telecom and industrial SMPS

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel 60 V power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP60NF06L	R_DS(on) = 14 mΩ @ 10 V; higher gate charge (Q_g = 45 nC); TO-220 package	Requires through-hole mounting and larger heatsink footprint; slower switching	Preferred only where through-hole assembly or legacy footprint compatibility is mandatory
IXTP48N06T	R_DS(on) = 12.5 mΩ @ 10 V; lower Q_g (28 nC); TO-220AB package	Lacks D-Pak thermal pad; R_θJC = 2.5°C/W limits power density in compact SMT designs	Acceptable for lower-power (<30 A) or less thermally constrained layouts

Compared with STP60NF06L and IXTP48N06T, IRFR3707ZTRRPBF delivers superior power density via D-Pak thermal pad and lowest R_DS(on), making it optimal for space-constrained, high-current SMT applications requiring <1.5°C/W thermal resistance.

FAQ

Is IRFR3707ZTRRPBF logic-level compatible?

Yes - its V_GS(th) range (2.0–4.0 V) and guaranteed R_DS(on) at V_GS = 4.5 V (22 mΩ max) confirm reliable enhancement with 5 V microcontroller outputs. However, full 11.5 mΩ performance requires 10 V gate drive.

What is the maximum continuous drain current at T_C = 25°C?

At T_C = 25°C, the absolute maximum continuous drain current is 79 A per the datasheet's DC rating. This assumes ideal heatsinking and is limited by package bondwire capacity, not silicon thermal limits.

Does IRFR3707ZTRRPBF have avalanche capability?

Yes - it is 100% tested for unclamped inductive switching (UIS) with E_AS = 190 mJ at T_J = 25°C. This rating applies to single-pulse conditions and supports robustness in relay replacement and inductive load switching.

Can IRFR3707ZTRRPBF be used in parallel configurations?

Yes - its positive temperature coefficient for R_DS(on) ensures inherent current sharing. For stable parallel operation, match gate resistors, minimize layout asymmetry, and ensure uniform PCB copper pour under each device's exposed drain pad.
