Product details

Overview

IRFRC20TRR 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 LED driver high-side switches.

For engineers reviewing the IRFRC20TRR datasheet, IRFRC20TRR pinout, IRFRC20TRR application, or IRFRC20TRR equivalent, key selection criteria include its 600 V blocking capability, surface-mount DPAK thermal performance (R_thJC = 3.0 °C/W), fast switching (t_r = 23 ns), body diode recovery time (t_rr = 290–580 ns), and Pb-free/halogen-free compliance per JEDEC TO-252AA.

Technical Context

This third-generation power MOSFET employs planar V-groove technology optimized for ruggedness and dynamic dV/dt immunity (3.0 V/ns). Its gate threshold voltage (2.0–4.0 V) ensures reliable turn-on with standard 10 V gate drivers while maintaining low leakage (I_DSS ≤ 100 μA at 600 V).

The device integrates a co-packaged body diode rated for 2.0 A continuous source-drain current and 8.0 A pulsed operation, with reverse recovery charge Q_rr of 0.67–1.3 μC - enabling use in freewheeling and snubberless flyback topologies without external diode substitution.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	600 V - supports primary-side switching in 400 V AC-input offline power supplies
R_DS(on)	4.4 Ω @ V_GS = 10 V - enables <1 W conduction loss at 2.0 A DC, suitable for low-power auxiliary rails
Q_g	18 nC - determines gate drive power requirement; compatible with low-current 10 V drivers (e.g., UC384x family)
E_AS	74 mJ - allows unclamped inductive switching without external snubbers in low-energy flyback circuits
t_rr	290–580 ns - limits diode reverse recovery losses in discontinuous conduction mode (DCM) operation
R_thJC	3.0 °C/W - enables 42 W power dissipation with minimal heatsinking when mounted on copper-clad PCB
I_D (T_C = 100 °C)	1.3 A - defines maximum continuous current under elevated ambient conditions in enclosed enclosures

Pinout & Package

DPAK (TO-252AA) surface-mount package with exposed drain pad for thermal conduction; standardized 3-pin layout compliant with JEDEC MS-012AC.

Pin/Terminal	Circuit Role	Design Meaning
G (Gate)	Control electrode	Receives 10 V logic-level signal; input capacitance C_iss = 350 pF affects drive timing and EMI filtering requirements
D (Drain)	High-voltage output terminal	Connected to 600 V rail; thermally bonded to exposed copper pad for junction-to-board heat transfer
S (Source)	Reference node / return path	Serves as common reference for gate drive and current sensing; internal source inductance L_S = 7.5 nH impacts switching waveform ringing

Key Features

Feature	Design Value
Dynamic dV/dt rating	3.0 V/ns - prevents false turn-on during high dv/dt transients in high-frequency SMPS
Repetitive avalanche rated	2.0 A I_AR, 4.2 mJ E_AR - sustains repeated inductive energy spikes without degradation in flyback snubberless designs
Surface-mount (DPAK)	Compatible with vapor-phase and IR reflow; requires ≥10.67 mm × 5.69 mm thermal pad per Application Note 826
Fast switching	t_d(on) = 10 ns, t_r = 23 ns - reduces switching losses in 100–500 kHz DC-DC converters
Low gate charge	Q_gs = 3.0 nC, Q_gd = 8.9 nC - minimizes Miller effect and improves controllability during hard switching

Equivalent & Alternatives

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

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) increases conduction loss; through-hole mounting requires different PCB layout	Prefer when higher current handling (6 A) and heatsink attachment are needed over surface-mount constraints
FQP6N60	600 V, 5.0 Ω R_DS(on), 22 nC Q_g, TO-220 package	Slower switching (t_r = 35 ns) and no avalanche rating limit use in unclamped inductive loads	Select only for cost-sensitive, low-frequency (<60 kHz), non-avalanche-critical applications with adequate snubbing

Compared with STP6NK60ZFP and FQP6N60, the IRFRC20TRR offers lower R_DS(on) and verified repetitive avalanche capability in a space-saving DPAK - making it preferable for compact, high-reliability auxiliary supplies where board area and transient robustness are critical.

FAQ

What is the maximum continuous drain current for IRFRC20TRR at 100 °C case temperature?

The IRFRC20TRR supports 1.3 A continuous drain current at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the DPAK package under sustained high-temperature operation and must be validated against actual PCB layout and airflow conditions. The IRFRC20TRR's R_thJC = 3.0 °C/W enables this current level when properly heatsunk to a 1" square FR-4 PCB.

Does IRFRC20TRR have avalanche capability, and is it rated for repetitive operation?

Yes, the IRFRC20TRR is explicitly rated for repetitive avalanche operation: I_AR = 2.0 A and E_AR = 4.2 mJ, with pulse width limited by maximum junction temperature. This capability is confirmed in the Absolute Maximum Ratings section and validated per Figure 12c in the datasheet. The IRFRC20TRR's avalanche rating allows safe operation in unclamped inductive switching circuits without external protection components.

What is the gate-source threshold voltage range for IRFRC20TRR, and how does it affect drive requirements?

The IRFRC20TRR has a gate-source threshold voltage V_GS(th) of 2.0–4.0 V at I_D = 250 μA, ensuring reliable turn-on with standard 10 V gate drivers while avoiding unintended conduction from noise. This range means the IRFRC20TRR is not a logic-level MOSFET and requires ≥8 V drive for full enhancement. The IRFRC20TRR's typical g_fs = 1.4 S provides predictable transconductance for analog control applications.

Can IRFRC20TRR be used in place of IRFUC20, and what is the key mechanical difference?

No - IRFRC20TRR uses the DPAK (TO-252) surface-mount package, while IRFUC20 uses the IPAK (TO-251) straight-lead through-hole package. Though electrically identical in ratings, the IRFRC20TRR cannot replace IRFUC20 without PCB redesign due to incompatible footprints and soldering methods. The IRFRC20TRR's DPAK variant is optimized for automated SMT assembly and improved thermal coupling to PCB copper planes.

What is the body diode reverse recovery time (t_rr) of IRFRC20TRR, and why does it matter in flyback designs?

The IRFRC20TRR body diode exhibits t_rr = 290–580 ns at T_J = 25 °C, I_F = 2.0 A, and dI/dt = 100 A/μs. In flyback converters, this parameter directly impacts switching losses during the diode's turn-off phase and influences EMI generation. Shorter t_rr reduces voltage overshoot and ringing, allowing the IRFRC20TRR to operate efficiently in DCM without external snubbers - a key advantage over slower-recovery alternatives.
