Product details

Overview

IRFRC20TRPBF-BE3 from Vishay Siliconix is a 600 V, 2.0 A N-channel surface-mount power MOSFET in DPAK (TO-252) package with 4.4 Ω R_DS(on) at V_GS = 10 V, 18 nC total gate charge, and repetitive avalanche rating-designed for high-voltage DC-DC converters, offline SMPS primary switches, and industrial motor control.

For engineers reviewing the IRFRC20TRPBF-BE3 datasheet, IRFRC20TRPBF-BE3 pinout, IRFRC20TRPBF-BE3 application, or IRFRC20TRPBF-BE3 equivalent, this page delivers verified electrical specs, thermal derating data, body diode recovery characteristics, and direct-mount PCB layout guidance per Vishay's recommended DPAK pad dimensions.

Technical Context

This third-generation power MOSFET employs planar V-groove technology optimized for rugged unclamped inductive switching, with 74 mJ single-pulse avalanche energy and 4.2 mJ repetitive avalanche capability. Its dynamic dV/dt rating of 3.0 V/ns supports reliable operation in fast-switching topologies without spurious turn-on.

The device features low gate charge (Q_g = 18 nC, Q_gd = 8.9 nC) and fast switching times (t_d(on) = 10 ns, t_f = 25 ns), enabling high-frequency operation up to 250 kHz in hard-switched converters while maintaining low conduction and switching losses.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	600 V - Supports 400 V AC input rectified systems with 50% safety margin
R_DS(on)	4.4 Ω @ V_GS = 10 V - Enables ≤2.0 A continuous drain current at T_C = 25 °C with <10 W conduction loss
Q_g	18 nC - Reduces gate drive power requirement and enables use with low-current drivers (e.g., 100 mA peak)
E_AS	74 mJ - Withstands unclamped inductive energy in flyback or forward converter snubberless designs
R_thJC	3.0 °C/W - Allows direct heatsink mounting for thermal management in high-power density layouts
V_SD	1.6 V @ I_S = 2.0 A - Defines forward voltage drop of integrated body diode during synchronous rectification or freewheeling
t_rr	290–580 ns - Critical for minimizing reverse recovery loss in quasi-resonant and LLC topologies

Pinout & Package

DPAK (TO-252) package with exposed drain tab for thermal conduction and mechanical anchoring; compatible with vapor-phase, infrared, and wave soldering per JEDEC standards.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (G)	Gate	Control terminal requiring ≤±20 V drive; low input capacitance (C_iss = 350 pF) minimizes Miller effect
Pin 2 (D)	Drain	Main high-side switching node; electrically connected to exposed metal tab for heatsinking
Pin 3 (S)	Source	Power return path and gate reference; internal source inductance (L_S = 7.5 nH) affects switching ringing

Key Features

Feature	Design Value
Repetitive avalanche rated	Supports 2.0 A repetitive avalanche current and 4.2 mJ energy-enables robust operation in overvoltage fault conditions without external clamping
Dynamic dV/dt rating	3.0 V/ns immunity prevents false turn-on during high dv/dt transients in bridge-leg configurations
Fast switching	10 ns turn-on delay + 25 ns fall time enables >200 kHz operation with minimal overlap loss
Surface-mount (DPAK)	Optimized for automated assembly and thermal performance on FR-4 PCBs with 1"² copper area (R_thJA = 50 °C/W)
Low Q_gd/Q_g ratio	8.9/18 = 0.49 - Improves hard-switching efficiency by reducing Miller plateau duration

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel high-voltage power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP6NK60ZFP	600 V, 5.5 Ω R_DS(on), 22 nC Q_g, TO-220FP package	Through-hole mounting only; higher R_DS(on) increases conduction loss at 2 A	Prefer when board space permits through-hole and higher thermal mass is needed
IXTP1R6N60P	600 V, 1.6 Ω R_DS(on), 24 nC Q_g, TO-220 package	Lower on-resistance but larger footprint and no surface-mount option	Choose when lower conduction loss outweighs PCB area and assembly constraints

Compared with STP6NK60ZFP and IXTP1R6N60P, IRFRC20TRPBF-BE3 offers the only DPAK-compatible 600 V solution with sub-5 Ω R_DS(on) and verified avalanche capability-making it optimal for compact, automated, high-reliability industrial power stages where thermal interface and layout density are critical.

FAQ

What is the maximum continuous drain current rating for IRFRC20TRPBF-BE3 at 100 °C case temperature?

The IRFRC20TRPBF-BE3 has a continuous drain current rating of 1.3 A at T_C = 100 °C, derived from its 2.0 A rating at 25 °C and linear derating factor of 0.33 W/°C. This value assumes proper PCB copper area (1"² FR-4) and thermal interface to heatsink. Exceeding this current without additional cooling risks junction temperature exceeding 150 °C.

Does IRFRC20TRPBF-BE3 support gate drive voltages below 10 V?

Yes, IRFRC20TRPBF-BE3 has a gate threshold voltage (V_GS(th)) range of 2.0–4.0 V, allowing partial enhancement at 5 V. However, full enhancement and specified R_DS(on) = 4.4 Ω require V_GS ≥ 10 V. Driving below 8 V increases on-resistance significantly and degrades switching speed and avalanche robustness.

What is the thermal resistance from junction to ambient for IRFRC20TRPBF-BE3 in standard PCB mount?

When mounted on a 1" square FR-4 PCB, the IRFRC20TRPBF-BE3 exhibits a maximum junction-to-ambient thermal resistance (R_thJA) of 50 °C/W. This value assumes no external heatsink and is critical for calculating worst-case junction temperature under steady-state power dissipation.

Can IRFRC20TRPBF-BE3 be used in avalanche mode repeatedly?

Yes, IRFRC20TRPBF-BE3 is explicitly rated for repetitive avalanche operation with I_AR = 2.0 A and E_AR = 4.2 mJ per pulse. This capability is validated per test condition: V_DD = 50 V, starting T_J = 25 °C, L = 37 mH, R_g = 25 Ω. Pulse width must remain within limits defined by maximum junction temperature (see Figure 11).

What are the recommended PCB pad dimensions for IRFRC20TRPBF-BE3 DPAK package?

Vishay recommends minimum PCB pads per Application Note 826: 0.224" × 0.180" (5.69 mm × 4.57 mm) for source, 0.243" × 0.087" (6.18 mm × 2.20 mm) for gate, and 0.420" × 0.055" (10.67 mm × 1.40 mm) for drain tab. A 1"² copper pour under the drain tab reduces R_thJA to 50 °C/W and improves power handling.
