Product details

Overview

IRFBC40PBF-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, 60 nC total gate charge, and repetitive avalanche rating. It serves as a high-voltage switching element in offline SMPS, AC-DC adapters, and industrial motor controls.

For engineers reviewing the IRFBC40PBF-BE3 datasheet, IRFBC40PBF-BE3 pinout, IRFBC40PBF-BE3 application, or IRFBC40PBF-BE3 equivalent, key selection criteria include its 600 V blocking capability, 1.2 Ω on-resistance at 10 V drive, 6.2 A continuous drain current at 25 °C, avalanche energy rating (570 mJ single-pulse), and TO-220AB thermal performance (R_thJC = 1.0 °C/W).

Technical Context

This third-generation power MOSFET uses planar V-groove technology to achieve ruggedized avalanche performance and stable dynamic dV/dt immunity up to 3.0 V/ns. Its gate threshold voltage (2.0–4.0 V) and low input capacitance (1300 pF) support simple drive with standard logic-level gate drivers.

The device integrates a fast-recovery body diode (t_rr = 450–940 ns, Q_rr = 3.8–7.9 μC) and exhibits linear SOA behavior up to 100 μs pulse width. Thermal design leverages the TO-220AB package's low junction-to-case resistance (1.0 °C/W) and flat greased mounting interface (R_thCS = 0.50 °C/W).

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	600 V - supports primary-side switching in universal-input 85–265 VAC offline converters
R_DS(on)	1.2 Ω @ V_GS = 10 V - enables <1.5 W conduction loss at 3.7 A DC current
Q_g	60 nC - determines gate driver power requirement and switching speed trade-off
I_D (continuous)	6.2 A @ T_C = 25 °C - defines maximum steady-state load current with heatsink
E_AS	570 mJ - allows safe unclamped inductive switching in flyback or forward topologies
t_rr	450–940 ns - limits diode reverse recovery losses and EMI in hard-switched applications
R_thJC	1.0 °C/W - enables direct thermal path to heatsink for 125 W dissipation at ΔT = 125 °C

Pinout & Package

TO-220AB package with isolated tab (drain-connected), vertical mounting orientation, and 6.35 mm lead pitch. Standard through-hole footprint compatible with IPC-7351B TO-220AB land pattern.

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 = 34 nC, TO-220FP package (full-pack)	Lower gate charge reduces driver loss but lower I_D rating limits peak power handling	Preferred where compact layout and lower drive power are critical; verify thermal margin at 6.2 A
FQP6N60C	600 V, 6.0 A, R_DS(on) = 1.3 Ω, Q_g = 52 nC, TO-220 package with non-isolated tab	Non-isolated drain tab requires insulating washer; slightly higher R_DS(on) increases conduction loss by ~8%	Cost-optimized alternative when heatsink isolation is already implemented externally

Compared with STP6NK60ZFP and FQP6N60C, the IRFBC40PBF-BE3 offers superior avalanche ruggedness (570 mJ vs. 320 mJ and 420 mJ), isolated TO-220AB tab for simplified heatsinking, and higher continuous current rating - making it preferred for industrial-grade reliability-critical designs.

FAQ

What is the maximum continuous drain current for IRFBC40PBF-BE3 at 100 °C case temperature?

The IRFBC40PBF-BE3 supports 3.9 A continuous drain current at T_C = 100 °C, per its absolute maximum ratings table. This derating reflects thermal limitations of the TO-220AB package and must be applied in thermally constrained layouts. Designers should verify junction temperature using R_thJC = 1.0 °C/W and actual power dissipation to ensure T_J ≤ 150 °C. The IRFBC40PBF-BE3 maintains safe operation within this limit when heatsinked appropriately.

Is IRFBC40PBF-BE3 suitable for use in circuits requiring RoHS and halogen-free compliance?

Yes, the IRFBC40PBF-BE3 is explicitly designated as lead (Pb)-free and halogen-free per Vishay's ordering nomenclature and complies with RoHS Directive 2011/65/EU. Its material categorization is confirmed in the official datasheet (S21-0868-Rev. C), and it meets JEDEC JS709C standards. The IRFBC40PBF-BE3 is appropriate for green manufacturing and export to EU, China, and other regulated markets requiring full substance compliance.

Does IRFBC40PBF-BE3 have an integrated body diode, and what are its key recovery parameters?

Yes, the IRFBC40PBF-BE3 includes an integral reverse p-n junction body diode. Its key recovery parameters are reverse recovery time t_rr = 450–940 ns and reverse recovery charge Q_rr = 3.8–7.9 μC, measured at T_J = 25 °C, I_F = 6.2 A, and dI/dt = 100 A/μs. These values directly impact switching loss and EMI in hard-switched topologies. The IRFBC40PBF-BE3's body diode performance is optimized for flyback and forward converter freewheeling paths.

What is the gate threshold voltage range for IRFBC40PBF-BE3, and how does it affect drive circuit design?

The gate threshold voltage V_GS(th) for IRFBC40PBF-BE3 is specified from 2.0 V to 4.0 V at I_D = 250 μA. This range confirms compatibility with standard 10 V gate drivers but indicates marginal turn-on with 5 V logic. To ensure full enhancement and low R_DS(on), a minimum 10 V drive is required. The IRFBC40PBF-BE3's threshold spread necessitates sufficient gate overdrive in noise-prone environments to avoid partial conduction and thermal runaway.

Can IRFBC40PBF-BE3 replace IRFBC40PBF in existing designs without layout changes?

Yes, the IRFBC40PBF-BE3 is a direct drop-in replacement for IRFBC40PBF, sharing identical TO-220AB package dimensions, pinout, and electrical specifications. The "-BE3" suffix denotes enhanced environmental compliance (halogen-free), with no functional or mechanical differences. Layout, thermal interface, and drive circuitry require no modification. The IRFBC40PBF-BE3 maintains full form-fit-function equivalence while meeting stricter material regulations.
