Product details

Overview

IRFR120TRL from Vishay Siliconix is a 100 V, 7.7 A N-channel surface-mount power MOSFET in DPAK (TO-252) package, featuring 0.27 Ω R_DS(on) at V_GS = 10 V, 16 nC total gate charge, and repetitive avalanche rating-designed for DC-DC converters, motor control, and load switching in industrial power supplies.

For engineers reviewing the IRFR120TRL datasheet, IRFR120TRL pinout, IRFR120TRL application, or IRFR120TRL equivalent, this page delivers verified electrical specs, thermal derating behavior, diode recovery characteristics, and surface-mount layout guidance per Vishay's recommended DPAK pad dimensions.

Technical Context

This third-generation TrenchFET® MOSFET uses optimized silicon die geometry to achieve low conduction loss while maintaining robust unclamped inductive switching capability (E_AS = 210 mJ). Its gate threshold voltage (2.0–4.0 V) ensures reliable turn-on with standard 10 V logic drivers.

The device integrates a fast-recovery body diode (t_rr = 130–260 ns, Q_rr = 0.65–1.3 μC) and supports high dV/dt immunity (5.5 V/ns), enabling stable operation in hard-switched topologies without external snubbers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - maximum blocking voltage for 24/48 V bus applications
R_DS(on)	0.27 Ω @ V_GS = 10 V - enables ≤1.3 W conduction loss at 7.7 A continuous drain current
Q_g	16 nC - determines gate drive power requirement and switching speed in PWM circuits
I_D (T_C = 25 °C)	7.7 A - continuous current rating under heatsink-cooled conditions
E_AS	210 mJ - single-pulse avalanche energy tolerance for inductive load protection
t_rr	130–260 ns - body diode reverse recovery time affecting shoot-through risk in half-bridge designs
R_thJC	3.0 °C/W - junction-to-case thermal resistance enabling direct heatsink mounting

Pinout & Package

Dynamic dV/dt rated	5.5 V/ns immunity prevents false turn-on during high-speed switching transients
Fast switching	Turn-on delay 6.8 ns, rise time 27 ns, fall time 17 ns-reduces switching losses in 100–500 kHz SMPS
Surface-mount (DPAK)	Compatible with vapor-phase, infrared, and wave soldering; requires Vishay-recommended 10.67 × 5.69 mm thermal pad
Low R_DS(on)/Q_g ratio	0.27 Ω / 16 nC = 16.9 mΩ·nC-balances conduction and switching loss for medium-frequency power stages

FAQ

What is the maximum continuous drain current for IRFR120TRL at 100 °C case temperature?

The IRFR120TRL supports 4.9 A continuous drain current at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derated value reflects thermal limitations of the DPAK package under sustained high-temperature operation and must be validated against actual PCB layout and heatsinking in the target application.

Does IRFR120TRL have a built-in body diode, and what are its key recovery characteristics?

Yes, the IRFR120TRL integrates a monolithic body diode with typical reverse recovery time (t_rr) of 130–260 ns and reverse recovery charge (Q_rr) of 0.65–1.3 μC at T_J = 25 °C. These values are measured under standardized conditions (I_F = 9.2 A, dI/dt = 100 A/μs) and directly impact shoot-through risk in synchronous rectification and half-bridge configurations.

What is the gate-source threshold voltage range for IRFR120TRL, and how does it affect drive compatibility?

The IRFR120TRL has a gate-source threshold voltage (V_GS(th)) range of 2.0–4.0 V at I_D = 250 μA. This ensures reliable turn-on with standard 5 V or 10 V logic-level drivers, but caution is required with 3.3 V controllers-full enhancement requires ≥10 V V_GS to achieve the rated 0.27 Ω R_DS(on).

Is IRFR120TRL suitable for avalanche operation, and what are the limits?

Yes, the IRFR120TRL is explicitly rated for repetitive avalanche operation with I_AR = 7.7 A and E_AR = 4.2 mJ per pulse. Single-pulse avalanche energy is rated at 210 mJ. Operation within these limits requires adherence to pulse width and duty cycle constraints defined in Figure 11 and 12 of the datasheet to prevent junction overheating.

What PCB pad dimensions are recommended for IRFR120TRL's DPAK (TO-252) package?

Vishay specifies a minimum thermal pad of 10.67 mm × 5.69 mm (0.420″ × 0.224″) for the IRFR120TRL DPAK footprint, per Application Note 826. This dimension ensures adequate copper area for thermal dissipation and mechanical reliability during reflow, especially when operating near maximum power limits.
