Product details
Overview
IRFRC20TRL from Vishay Siliconix is a 600 V, 2.0 A N-channel surface-mount power MOSFET in DPAK (TO-252) package, featuring 4.4 Ω RDS(on) at VGS = 10 V, 18 nC total gate charge, and repetitive avalanche rating up to 2.0 A - designed for high-voltage DC-DC converters and offline switch-mode power supplies.
For engineers reviewing the IRFRC20TRL datasheet, IRFRC20TRL pinout, IRFRC20TRL application, or IRFRC20TRL equivalent, this page delivers verified electrical parameters, thermal derating behavior, body diode recovery characteristics, and surface-mount layout guidance specific to the IRFRC20TRL variant with Pb-free/roHS-compliant BE3 manufacturing marking.
Technical Context
This third-generation high-voltage MOSFET employs planar stripe cell structure optimized for ruggedness and fast switching, with dynamic dV/dt rating of 3.0 V/ns and unclamped inductive switching capability validated to 74 mJ single-pulse and 4.2 mJ repetitive avalanche energy. Its gate threshold voltage (2.0–4.0 V) ensures reliable turn-on with standard 10 V gate drivers.
The device integrates a low-Qrr (0.67–1.3 μC) body diode with 290–580 ns reverse recovery time, enabling efficient hard-switched flyback and forward topologies. Thermal resistance from junction-to-case is 3.0 °C/W, supporting 42 W continuous dissipation at TC = 25 °C when mounted on heatsink-equipped PCBs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SiHFRC20TRL-GE3 | Same die, identical RDS(on), Qg, and avalanche specs; differs only in halogen-free plating and GE3 facility code | No functional difference; qualified for same automotive and industrial temperature ranges (−55 to +150 °C) | Select SiHFRC20TRL-GE3 if halogen-free compliance per IEC 61249-2-21 is required. |
| IRFUC20PbF | Same silicon but IPAK (TO-251) through-hole package; higher RthJA (110 °C/W vs. 50 °C/W PCB mount), no exposed drain pad | Requires wave soldering; unsuitable for high-density SMT layouts; lower thermal performance in compact enclosures | Choose IRFUC20PbF only when through-hole assembly or legacy board compatibility is mandatory. |

FAQ
What is the maximum continuous drain current for IRFRC20TRL at 100 °C case temperature?
The IRFRC20TRL supports 1.3 A continuous drain current at TC = 100 °C, as specified in the Absolute Maximum Ratings table. This derated value accounts for thermal limitations in surface-mount configurations without active cooling. Designers must verify PCB copper area and ambient airflow to sustain this current reliably in end equipment. The IRFRC20TRL's 3.0 °C/W junction-to-case thermal resistance enables this performance when the drain pad is fully soldered to a thermal plane.
Does IRFRC20TRL have a built-in body diode, and what are its key recovery parameters?
Yes, the IRFRC20TRL integrates a monolithic body diode with typical reverse recovery time (trr) of 290 ns and maximum of 580 ns at TJ = 25 °C, IF = 2.0 A, and dI/dt = 100 A/μs. Its reverse recovery charge (Qrr) ranges from 0.67 to 1.3 μC. These values directly impact switching loss and EMI in hard-commutated topologies. The IRFRC20TRL's low Qrr supports efficient operation in discontinuous conduction mode flyback converters without requiring external Schottky catch diodes.
Is IRFRC20TRL pin-compatible with other devices in the IRFRC20/SiHFRC20 family?
Yes, the IRFRC20TRL shares identical DPAK (TO-252) pinout and footprint with all IRFRC20 and SiHFRC20 variants, including SiHFRC20TRL-GE3 and IRFRC20TRLPbF-BE3. All use G-D-S terminal arrangement with drain connected to the exposed thermal pad. No PCB layout changes are needed when substituting within this family, provided solder mask and thermal pad design follow Vishay's recommended minimum pads for DPAK outlined in Application Note 826.
What is the gate threshold voltage range for IRFRC20TRL, and how does it affect drive requirements?
The IRFRC20TRL has a gate-source threshold voltage (VGS(th)) range of 2.0 V to 4.0 V at ID = 250 μA. This ensures reliable turn-on with standard 5 V or 10 V logic-level gate drivers, while maintaining noise immunity against spurious gate excitation. For full enhancement, VGS ≥ 10 V is required to achieve the specified 4.4 Ω RDS(on). The IRFRC20TRL's threshold stability across temperature supports consistent switching behavior in industrial environments up to +150 °C junction temperature.
How is the avalanche capability of IRFRC20TRL characterized, and what design margin does it provide?
The IRFRC20TRL is rated for repetitive avalanche energy (EAR) of 4.2 mJ and single-pulse avalanche energy (EAS) of 74 mJ under defined test conditions (L = 37 mH, IAS = 2.0 A). This ruggedness allows safe operation during transient overloads, such as transformer saturation or short-circuit events in SMPS, without requiring external protection circuits. The IRFRC20TRL's avalanche rating is validated per JEDEC standards and provides a design margin that simplifies reliability validation for industrial-grade power supplies.
