Product details

Overview

IRFRC20TRLPBF-BE3 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 flyback and offline SMPS primary-side switching.

For engineers reviewing the IRFRC20TRLPBF-BE3 datasheet, IRFRC20TRLPBF-BE3 pinout, IRFRC20TRLPBF-BE3 application, or IRFRC20TRLPBF-BE3 equivalent, this part supports stable high-voltage DC-DC conversion, unclamped inductive switching, and thermally constrained PCB-mount designs requiring ≤2.5 W dissipation on FR-4.

Technical Context

This third-generation silicon power MOSFET uses planar stripe cell structure optimized for ruggedness and fast switching, with dynamic dV/dt rating of 3.0 V/ns and body diode reverse recovery time of 290–580 ns under specified conditions. Its gate threshold voltage (2.0–4.0 V) and low Q_gd/Q_g ratio (8.9/18 nC) support reliable hard-switching operation in discontinuous conduction mode (DCM) topologies.

The device is rated for repetitive avalanche energy (4.2 mJ) and single-pulse avalanche energy (74 mJ), enabling robust operation in snubberless flyback converters. Thermal resistance R_thJC = 3.0 °C/W and R_thJA = 50 °C/W (PCB mount) confirm suitability for surface-mount thermal management without heatsinks in low-power adapters.

R_DS(on)	4.4 Ω @ V_GS = 10 V - determines conduction loss in primary switch; enables <2.0 W P_cond at 1.2 A RMS
Q_g	18 nC - defines gate drive power requirement; compatible with standard 10–15 V PWM controllers
I_D (T_C = 25 °C)	2.0 A - maximum continuous drain current under ideal heatsink conditions

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
STP6NK60ZFP	600 V, 6 A, R_DS(on) = 1.2 Ω, TO-220FP package, Zener-protected gate	Higher current rating but larger footprint and higher gate charge (32 nC); requires heatsink for >1.5 A	Choose when higher continuous current or integrated gate protection is required; not drop-in due to package and pinout mismatch
IXTP2N60P	600 V, 2.0 A, R_DS(on) = 4.5 Ω, TO-220 package, no avalanche rating	Lacks repetitive avalanche capability; higher R_thJA (62 °C/W) limits PCB-mount power handling	Acceptable only in snubber-protected circuits with strict thermal layout control; not suitable for snubberless flyback

Compared with STP6NK60ZFP and IXTP2N60P, the IRFRC20TRLPBF-BE3 offers superior avalanche ruggedness and surface-mount compatibility for space-constrained 5–15 W designs, while maintaining competitive R_DS(on) and lower gate drive demand than the STMicro part.

FAQ

What is the maximum continuous drain current for IRFRC20TRLPBF-BE3 at 100 °C case temperature?

The IRFRC20TRLPBF-BE3 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 mounted on standard FR-4 PCB; actual usable current depends on layout, copper area, and ambient conditions. The IRFRC20TRLPBF-BE3 must be operated within this limit to avoid exceeding 150 °C junction temperature.

Does IRFRC20TRLPBF-BE3 have a specified avalanche energy rating?

Yes, the IRFRC20TRLPBF-BE3 is rated for 74 mJ single-pulse avalanche energy (E_AS) and 4.2 mJ repetitive avalanche energy (E_AR). These values are measured under defined test conditions (V_DD = 50 V, L = 37 mH, I_AS = 2.0 A) and enable snubberless operation in flyback converters. The IRFRC20TRLPBF-BE3 data sheet confirms repetitive rating with pulse width limited by junction temperature.

What is the gate-source threshold voltage range for IRFRC20TRLPBF-BE3?

The gate-source threshold voltage (V_GS(th)) for IRFRC20TRLPBF-BE3 is specified from 2.0 V to 4.0 V at T_J = 25 °C and I_D = 250 μA. This range indicates the minimum gate voltage needed to initiate conduction; full enhancement requires ≥10 V drive. The IRFRC20TRLPBF-BE3 is not a logic-level device and requires dedicated gate driver circuitry for reliable switching.

Can IRFRC20TRLPBF-BE3 be used in through-hole designs?

No - the IRFRC20TRLPBF-BE3 is exclusively offered in DPAK (TO-252) surface-mount package, as confirmed by ordering information and package drawings. Through-hole variants (e.g., IRFUC20 series) exist but are distinct part numbers with different lead forms and thermal characteristics. Substituting IRFRC20TRLPBF-BE3 into through-hole layouts is not mechanically or thermally viable.

What is the typical body diode reverse recovery time for IRFRC20TRLPBF-BE3?

The body diode reverse recovery time (t_rr) for IRFRC20TRLPBF-BE3 is 290–580 ns, measured at T_J = 25 °C, I_F = 2.0 A, and dI/dt = 100 A/μs. This parameter directly affects switching losses and EMI in flyback and resonant converters. The IRFRC20TRLPBF-BE3 datasheet specifies t_rr across this range to account for process variation and test condition tolerances.
