Product details

Overview

IRFBC40APBF-BE3 from Vishay Siliconix is a 600 V, 6.2 A N-channel power MOSFET in TO-220AB package, featuring 1.2 Ω R_DS(on) at V_GS = 10 V, 42 nC total gate charge, and 570 mJ single-pulse avalanche energy - designed for high-voltage SMPS primary-side switching.

For engineers reviewing the IRFBC40APBF-BE3 datasheet, IRFBC40APBF-BE3 pinout, IRFBC40APBF-BE3 application, or IRFBC40APBF-BE3 equivalent, key selection criteria include avalanche ruggedness, dV/dt immunity (6.0 V/ns), body diode recovery (431–647 ns), and thermal resistance (R_thJC = 1.0 °C/W) in high-reliability offline power stages.

Technical Context

This device employs a planar vertical DMOS structure optimized for high-voltage unclamped inductive switching. Its fully characterized C_oss (136 pF typ.) and C_{oss eff.} (48 pF) support predictable snubber design in flyback and forward converters.

Gate drive is simplified by low Q_g (42 nC) and moderate Q_gd/Q_gs ratio (2.0), enabling robust operation with standard 10 V gate drivers. The integral body diode exhibits 1.5 V forward drop at 6.2 A and controlled reverse recovery (Q_rr = 1.8–2.8 μC).

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	600 V - supports 400 V AC mains input with 20 % margin in offline SMPS
R_DS(on)	1.2 Ω @ V_GS = 10 V - enables <6.2 A continuous conduction at T_C = 100 °C with ≤7.5 W conduction loss
Q_g	42 nC - allows fast turn-on/turn-off with ≤9.1 Ω gate resistor while limiting driver power dissipation
E_AS	570 mJ - withstands unclamped inductive energy in single-pulse fault conditions without failure
dV/dt rating	6.0 V/ns - ensures noise-immune operation during high-slew-rate switching in high-density layouts
R_thJC	1.0 °C/W - enables 125 W power dissipation with ≤125 °C junction rise above heatsink at T_C = 25 °C
Body diode t_rr	431–647 ns - defines minimum dead-time requirements in synchronous rectification or half-bridge topologies

Pinout & Package

TO-220AB package with isolated tab (drain-connected), standard 3-lead through-hole mounting, 1.0 mm lead pitch, and 1.1 N·m maximum mounting torque.

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, 5.5 A, R_DS(on) = 1.2 Ω, Q_g = 32 nC, TO-220FP package (full-pack)	Lower peak current rating; shorter avalanche time constant due to lower E_AS (320 mJ)	Preferred where space-constrained PCB layout favors insulated package; requires verification of thermal interface with heatsink
FQP6N60C	600 V, 6.0 A, R_DS(on) = 1.3 Ω, Q_g = 34 nC, TO-220 package with non-isolated tab	Non-isolated drain tab necessitates insulating washer; slightly higher conduction loss at full load	Cost-optimized alternative when heatsink isolation is already implemented via mechanical means

Compared with STP6NK60ZFP and FQP6N60C, the IRFBC40APBF-BE3 delivers superior single-pulse avalanche robustness (570 mJ vs. ≤320 mJ) and higher continuous current capability (6.2 A vs. ≤6.0 A), making it preferred for mission-critical offline power stages requiring field reliability under transient overload.

FAQ

What is the maximum continuous drain current for IRFBC40APBF-BE3 at 100 °C case temperature?

The IRFBC40APBF-BE3 supports 3.9 A continuous drain current at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits of the TO-220AB package and ensures junction temperature remains within the -55 °C to +150 °C operating range under sustained load conditions. The IRFBC40APBF-BE3 maintains R_DS(on) stability up to 150 °C junction temperature.

Does IRFBC40APBF-BE3 have an isolated drain tab?

Yes, the IRFBC40APBF-BE3 uses a TO-220AB package with an electrically isolated metal tab internally connected to the drain. This allows direct mounting to a grounded heatsink without additional insulation, provided the mounting hardware does not short the tab to other potentials. The IRFBC40APBF-BE3 datasheet specifies R_thCS = 0.50 °C/W for flat, greased surface contact.

What is the typical body diode reverse recovery charge (Q_rr) of IRFBC40APBF-BE3?

The IRFBC40APBF-BE3 has a typical body diode reverse recovery charge of 1.8 μC, with a maximum of 2.8 μC at T_J = 25 °C, I_F = 6.2 A, and dI/dt = 100 A/μs. This parameter directly impacts switching losses and EMI in hard-switched topologies. The IRFBC40APBF-BE3's Q_rr is fully characterized and validated per JEDEC standards.

Is IRFBC40APBF-BE3 suitable for use in zero-voltage switching (ZVS) circuits?

The IRFBC40APBF-BE3 is compatible with ZVS operation due to its well-defined C_oss (136 pF typ.) and C_{oss eff.} (48 pF), which enable predictable resonant timing. However, its 600 V rating and 1.2 Ω R_DS(on) make it most effective in 300–400 V bus ZVS designs rather than ultra-high-frequency LLC resonant converters. The IRFBC40APBF-BE3's dV/dt rating supports clean ZVS transitions without spurious turn-on.

What is the gate-source leakage current specification for IRFBC40APBF-BE3?

The IRFBC40APBF-BE3 specifies gate-source leakage current (I_GSS) as ±100 nA maximum at V_GS = ±30 V and T_J = 25 °C. This low leakage ensures stable gate bias in high-impedance drive circuits and contributes to low standby power consumption in always-on SMPS controllers. The IRFBC40APBF-BE3 maintains this performance across its full operating temperature range.
