Product details

Overview

IRFR120ZTRL from Infineon Technologies (formerly International Rectifier) is an N-channel enhancement-mode HEXFET® Power MOSFET in D-Pak (TO-252) package, rated for 100V V_DSS, 8.7A continuous drain current at T_C = 25°C, and 190 mΩ R_DS(on) at V_GS = 10V. It features 175°C maximum junction temperature, fast switching (t_d(on) = 8.3 ns, t_f = 23 ns), and rated repetitive avalanche capability-designed for high-efficiency DC-DC converters, motor drive half-bridges, and industrial power supplies.

For engineers reviewing the IRFR120ZTRL datasheet, IRFR120ZTRL pinout, IRFR120ZTRL application, or IRFR120ZTRL equivalent, key selection criteria include verified R_DS(on) at 10V gate drive, thermal resistance R_θJC = 4.28°C/W, body diode reverse recovery charge Q_rr = 23–35 nC, and avalanche energy rating E_AS = 18 mJ (tested).

Technical Context

This MOSFET employs advanced silicon processing to minimize on-resistance per die area while maintaining robust safe operating area (SOA) up to 100V and 8.7A. Its gate threshold voltage (V_GS(th)) ranges 2.0–4.0V, enabling reliable turn-on with standard 3.3V/5V logic-level drivers when combined with sufficient gate charge (Q_g = 6.9–10 nC).

The integrated body diode exhibits V_SD = 1.3V max at I_S = 5.2A and t_rr = 24–36 ns, supporting synchronous rectification and unclamped inductive switching. Thermal design is enabled by low R_θJC (4.28°C/W) and validated transient impedance curves up to 1 ms pulse width.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	100 V - Withstands up to 100V drain-source blocking voltage before avalanche onset.
R_DS(on)	190 mΩ max @ V_GS = 10V, T_J = 25°C - Determines conduction loss in high-current paths (e.g., 0.85W loss at 8.7A).
I_D (cont)	8.7 A @ T_C = 25°C - Continuous current capability under heatsink-cooled conditions.
Q_g	10 nC max - Total gate charge defining driver strength requirement for 10–100 ns switching transitions.
E_AS	18 mJ (tested) - Single-pulse avalanche energy handling without failure, critical for inductive load snubbing.
T_J max	175°C - Enables operation in high-ambient environments (e.g., enclosed industrial enclosures).
R_θJC	4.28°C/W - Junction-to-case thermal resistance; defines minimum heatsink interface performance needed for thermal management.

Pinout & Package

IRFR120ZTRL uses the D-Pak (TO-252) surface-mount package with exposed drain pad for thermal and electrical connection. The three terminals are arranged in a single-row configuration with Gull-wing leads.

Pin/Terminal	Circuit Role	Design Meaning
Drain (D)	Main current-carrying terminal (connected to internal die substrate)	Electrically and thermally tied to exposed copper pad; must be soldered to large PCB copper pour for heat dissipation.
Source (S)	Reference node for gate drive and current return path	Low-inductance source connection essential for minimizing switching oscillation; LS = 7.5 nH typical.
Gate (G)	Control electrode for channel formation	High-impedance input requiring <200 nA leakage; sensitive to ESD; requires gate resistor (RG ≈ 53 Ω typical) for controlled dV/dt.

Key Features

Feature	Design Value
Ultra-low R_DS(on)	190 mΩ max at 10V drive enables >95% efficiency in 12–48V buck converters at 5–8A load.
175°C junction rating	Supports operation in sealed enclosures or high-ambient environments without derating below 100°C ambient.
Fast switching speed	t_f = 23 ns and t_d(off) = 27 ns reduce switching losses in 100–500 kHz SMPS designs.
Repetitive avalanche rated	Validated for repeated unclamped inductive switching up to T_Jmax, eliminating need for external clamping in relay/motor drive snubbers.
Lead-free construction	RoHS-compliant D-Pak package with matte tin lead finish, compatible with standard reflow profiles.

Applications

DC-DC Buck Converter

Brushed DC Motor Driver

Use Scenario: High-efficiency 24V-to-5V/3.3V point-of-load converter in industrial PLC modules.

IC Role / Device Role / Timing Role: Synchronous high-side switch operating at 300 kHz with gate-driven body diode commutation.

Use Value: Low R_DS(on) reduces conduction loss; fast t_f minimizes dead-time losses; 175°C rating ensures reliability under full-load thermal stress.

Use Scenario: H-bridge driver for 24V brushed motors in automated gate actuators.

IC Role / Device Role / Timing Role: Low-side switch controlling motor direction and PWM speed via microcontroller GPIO.

Use Value: Rated repetitive avalanche handles back-EMF spikes during PWM turn-off; Q_rr = 23–35 nC limits diode recovery loss during polarity reversal.

AC-DC Auxiliary Supply

LED Constant-Current Driver

Use Scenario: 12V auxiliary rail generation in offline flyback converters for smart meter power supplies.

IC Role / Device Role / Timing Role: Primary-side active clamp switch managing transformer reset energy.

Use Value: 100V V_DSS accommodates reflected flyback voltage plus margin; E_AS = 18 mJ absorbs clamp energy without external Zener.

Use Scenario: Buck-based constant-current driver for high-brightness LED strings in street lighting fixtures.

IC Role / Device Role / Timing Role: High-side current-regulating switch modulated at 1–20 kHz for dimming control.

Use Value: Low R_DS(on) maintains <1W dissipation at 8.7A LED current; thermal R_θJC = 4.28°C/W allows direct mounting to aluminum heatsink.

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
STP12NK100Z	100V V_DSS, 12A I_D, 180 mΩ R_DS(on), TO-220 package	Higher current rating but through-hole only; lacks D-Pak thermal interface and surface-mount compatibility	Select for prototyping or low-volume through-hole boards where heatsink mounting flexibility outweighs PCB space constraints.
IXTP10N100D2	100V V_DSS, 10A I_D, 220 mΩ R_DS(on), TO-220FP package	Higher R_DS(on) and lower I_D; optimized for linear-mode operation with enhanced SOA	Prefer for analog pass-element or hot-swap applications where ruggedness under linear bias matters more than switching efficiency.

Compared with STP12NK100Z and IXTP10N100D2, IRFR120ZTRL offers superior surface-mount thermal performance (R_θJC = 4.28°C/W vs. >1.5°C/W for TO-220 variants) and tighter gate threshold distribution (2.0–4.0V), making it optimal for high-density, high-reliability automated assembly in industrial power stages.

FAQ

Is IRFR120ZTRL suitable for logic-level gate drive?

No-IRFR120ZTRL has a gate threshold voltage range of 2.0–4.0V and is specified for R_DS(on) at V_GS = 10V. While it may weakly turn on with 3.3V or 5V, full enhancement requires ≥10V gate drive to achieve 190 mΩ R_DS(on). For true logic-level operation, consider IRFR024N or similar 2.5V-threshold parts.

What is the maximum recommended PCB copper area for the drain pad?

Per Infineon's layout guidelines, the exposed drain pad should connect to ≥250 mm² of 2-oz copper (minimum 1.5 mm² per amp), with ≥4 thermal vias (0.3 mm diameter, filled or plated) to inner ground/power planes. This achieves near-datasheet R_θJC = 4.28°C/W and prevents localized overheating at 8.7A.

Does IRFR120ZTRL include integrated gate protection?

No-it lacks built-in gate Zener clamping or series resistance. External gate protection is required: a 12–15V Zener diode between gate and source (cathode to gate), plus a 10–100Ω series resistor, is mandatory to prevent V_GS overstress from ringing or ESD, especially in high-dV/dt switching environments.

Can IRFR120ZTRL replace IRFR120 in existing designs?

Yes-with caveats. IRFR120ZTRL replaces IRFR120 (obsolete) with identical pinout, package, and electrical specs, but adds lead-free finish and improved repetitive avalanche rating. Verify board reflow profile compatibility with matte tin finish and confirm no legacy design relies on non-RoHS solder paste compatibility.
