Product details

Overview

IRF3710ZLPBF from Infineon Technologies (formerly International Rectifier) is a 100V, 59A N-channel enhancement-mode Power MOSFET in TO-262 (I²PAK) package, featuring 14–18 mΩ R_DS(on) at V_GS = 10 V, 175°C maximum junction temperature, and rated for repetitive avalanche operation. It serves as a high-current, low-loss switching element in DC-DC converters, motor drives, and uninterruptible power supplies.

For engineers reviewing the IRF3710ZLPBF datasheet, IRF3710ZLPBF pinout, IRF3710ZLPBF application, or IRF3710ZLPBF equivalent, key selection criteria include its 100V V_DS, 59A continuous drain rating at T_C = 25°C, 82–120 nC total gate charge, fast 77 ns rise time, and robust 170 mJ single-pulse avalanche energy - all critical for hard-switched industrial power stages.

Technical Context

This MOSFET employs advanced planar HEXFET® process technology to minimize conduction losses while maintaining ruggedness under transient overloads. Its design supports unclamped inductive switching with validated repetitive avalanche capability up to I_AS = 35 A and E_AR = 200 mJ at T_J = 25°C.

The device integrates an intrinsic body diode with 1.3 V forward voltage (V_SD) at 35 A and 50–75 ns reverse recovery time (t_rr), enabling synchronous rectification and freewheeling in buck and half-bridge topologies without external diodes.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - Withstands up to 100 V drain-source blocking voltage, suitable for 48 V bus and 100 V industrial input systems.
R_DS(on)	14–18 mΩ @ V_GS = 10 V - Enables <1.1 W conduction loss at 35 A, reducing heatsink requirements in high-current switch nodes.
I_D (continuous)	59 A @ T_C = 25°C - Delivers high output current in TO-262 package with 0.92 °C/W junction-to-case thermal resistance.
Q_g	82–120 nC - Determines gate drive power and switching speed; compatible with standard 1–2 A peak gate drivers.
E_AS	170 mJ - Specifies single-pulse avalanche energy limit; allows safe operation during inductive turn-off transients without snubbers.
t_r/t_f	77 ns / 56 ns - Fast edge rates support >100 kHz switching in SMPS designs while limiting switching loss.
T_J(max)	175°C - Supports operation in high-ambient environments such as enclosed motor controllers or sealed UPS enclosures.

Pinout & Package

IRF3710ZLPBF is housed in a TO-262 (I²PAK) surface-mount-compatible package with isolated tab (drain-connected), optimized for PCB thermal management using a large copper pour and thermal vias.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main current path from source to load	Electrically connected to metal tab; requires insulated mounting or isolation pad when mounted to heatsink.
Source	Reference node for gate control and current return	Low-inductance connection point for gate driver return and sense resistor placement; internal source inductance = 7.5 nH.
Gate	Control terminal for channel modulation	High-impedance input requiring <120 nC charge; sensitive to ringing - layout must minimize loop area with gate resistor close to package.

Key Features

Feature	Design Value
Ultra-low R_DS(on)	14–18 mΩ enables <1.1 W conduction loss at 35 A, reducing thermal stress in high-current power stages.
Repetitive avalanche rated	Validated for repeated unclamped inductive switching up to I_AS = 35 A and E_AR = 200 mJ, eliminating need for external clamping in many motor drive applications.
175°C operating junction temperature	Allows full-rated performance in ambient temperatures up to 100°C with proper PCB thermal design, extending reliability in sealed enclosures.
Fast switching with low Q_gd/Q_gs	27–40 nC Miller charge and 19–28 nC gate-to-source charge reduce susceptibility to dv/dt-induced turn-on and improve hard-switching efficiency.

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
STP110N10F7	100 V, 110 A, 7.5 mΩ R_DS(on), TO-220FP package, lower R_DS(on) but higher Q_g (130 nC)	Higher current rating suits larger inverters; less suitable for space-constrained TO-262 layouts	Select when board space permits TO-220FP and lower conduction loss outweighs gate drive complexity.
IXTH50N10L2	100 V, 50 A, 12 mΩ R_DS(on), TO-247 package, 150°C T_J(max), no repetitive avalanche rating	Limited avalanche capability requires external protection in inductive loads; better thermal performance in forced-air cooling	Prefer for high-reliability linear-regulated supplies where avalanche stress is absent and heatsinking is optimized.

Compared with STP110N10F7 and IXTH50N10L2, IRF3710ZLPBF offers balanced trade-offs: TO-262 footprint compatibility, verified repetitive avalanche behavior, and mid-range R_DS(on)/Q_g ideal for cost-sensitive industrial motor drives and UPS systems requiring field-proven ruggedness.

FAQ

Is IRF3710ZLPBF RoHS-compliant and lead-free?

Yes. IRF3710ZLPBF carries the "PbF" suffix per Infineon's marking convention, confirming full compliance with RoHS Directive 2011/65/EU and exemption 7a. The device uses lead-free terminations and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) for unlimited floor life at ≤30°C/85% RH.

What is the recommended gate resistor value for IRF3710ZLPBF in a 100 kHz buck converter?

A 10 Ω non-inductive gate resistor is recommended for 100 kHz operation, balancing switching speed (t_r/t_f ≈ 77/56 ns) against gate driver stress and EMI. Layout must keep gate loop inductance <5 nH; values below 5 Ω increase risk of oscillation due to 7.5 nH internal source inductance.

Does IRF3710ZLPBF require a heatsink in TO-262 mounting?

Yes. At 59 A continuous current, junction-to-ambient thermal resistance is 40 °C/W (PCB mount). With 1.1 W conduction loss and 0.5 W switching loss, ΔT_J-A exceeds 60°C - necessitating a minimum 25 cm² copper pour with 6+ thermal vias, or an external heatsink for ambient >50°C.

Can IRF3710ZLPBF replace IRF3710PBF in existing designs?

Yes, with mechanical verification. Both share identical electrical specs and TO-262 package outline, but IRF3710ZLPBF uses enhanced leadframe plating for improved solderability and wirebond reliability. No circuit requalification is needed unless the original design operated near thermal limits - then verify junction temperature with the updated R_θJC = 0.92 °C/W.
