Product details

Overview

IRFRC20TR from Vishay Siliconix is a 600 V, 2.0 A N-channel power MOSFET in DPAK (TO-252) package, featuring 4.4 Ω R_DS(on) at V_GS = 10 V, 18 nC total gate charge, and repetitive avalanche rating up to 2.0 A - designed for high-voltage DC-DC converters, offline SMPS auxiliary supplies, and industrial motor control snubbers.

For engineers reviewing the IRFRC20TR datasheet, IRFRC20TR pinout, IRFRC20TR application, or IRFRC20TR equivalent, this page delivers verified electrical parameters, thermal derating behavior, body diode recovery characteristics (t_rr = 290–580 ns), and surface-mount packaging details essential for reliable high-voltage switching design.

Technical Context

This device belongs to Vishay's third-generation high-voltage power MOSFET family optimized for fast switching and ruggedness. Its dynamic dV/dt rating of 3.0 V/ns and unclamped inductive switching capability (E_AS = 74 mJ) support robust operation in hard-switched topologies with inductive loads.

The IRFRC20TR integrates a low-Q_gd/Q_g ratio (8.9/18 nC) and low output capacitance (C_oss = 48 pF), enabling efficient zero-voltage transition (ZVT) soft-switching in resonant converters while maintaining stable gate drive under high dv/dt conditions.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP6NK60ZFP	600 V, 5.5 Ω R_DS(on), 16 nC Q_g, TO-220FP package	Higher R_DS(on) but lower Q_g; through-hole mounting only	Select when board space allows through-hole and lower gate drive power is prioritized over conduction loss
IXTP2N60P	600 V, 5.2 Ω R_DS(on), 14 nC Q_g, TO-220 package	Higher on-resistance, no avalanche rating, larger thermal resistance (R_thJC = 3.5 °C/W)	Choose for cost-sensitive non-avalanche applications where DPAK footprint is not required

Compared with STP6NK60ZFP and IXTP2N60P, the IRFRC20TR offers superior avalanche ruggedness, lower R_DS(on), and surface-mount compatibility - making it preferred for compact, high-reliability industrial power supplies where transient stress and automated assembly are critical.

FAQ

What is the maximum continuous drain current for IRFRC20TR at 100 °C case temperature?

The IRFRC20TR supports 1.3 A continuous drain current at T_C = 100 °C, per its absolute maximum ratings table. This derating reflects thermal limitations of the DPAK package under sustained power dissipation; designers must verify junction temperature using R_thJC = 3.0 °C/W and actual power loss to ensure T_J ≤ 150 °C. The IRFRC20TR's linear derating factor is 0.33 W/°C above 25 °C case temperature.

Does IRFRC20TR have a specified avalanche energy rating?

Yes, the IRFRC20TR is repetitively avalanche rated with E_AR = 4.2 mJ and I_AR = 2.0 A, and single-pulse avalanche energy E_AS = 74 mJ. These values are measured under defined test conditions (V_DD = 50 V, L = 37 mH, R_g = 25 Ω, T_J initial = 25 °C). The IRFRC20TR's avalanche capability is validated per JEDEC standards and enables reliable operation in inductive switching without external snubbers.

What is the gate threshold voltage range for IRFRC20TR?

The IRFRC20TR has a gate-source threshold voltage V_GS(th) ranging from 2.0 V to 4.0 V at V_DS = V_GS and I_D = 250 μA. This range indicates the minimum gate voltage required to begin channel conduction; full enhancement occurs at V_GS = 10 V, where R_DS(on) is guaranteed at 4.4 Ω. The IRFRC20TR is not a logic-level MOSFET and requires dedicated 10 V gate drive for optimal performance.

Can IRFRC20TR be used in parallel with identical devices?

Yes, the IRFRC20TR is designed for ease of paralleling due to its positive temperature coefficient of R_DS(on), which promotes current sharing across multiple devices. Layout symmetry, matched gate drive impedance, and thermal coupling are critical; the IRFRC20TR's low Q_gd/Q_g ratio further enhances stability during simultaneous switching. Parallel operation is validated in Vishay's application notes for high-current SMPS designs.

What is the body diode reverse recovery time (t_rr) specification for IRFRC20TR?

The IRFRC20TR specifies body diode reverse recovery time t_rr = 290–580 ns at T_J = 25 °C, I_F = 2.0 A, and dI/dt = 100 A/μs. This parameter directly affects switching loss and EMI in synchronous rectification or half-bridge freewheeling applications. The IRFRC20TR's t_rr is characterized with its integral source-drain diode and must be considered when selecting gate drive timing to avoid cross-conduction.
