Product details
Overview
IRFBC40ASTRRPBF from Vishay Siliconix is a 600 V, 6.2 A N-channel power MOSFET in D2PAK (TO-263) package, featuring 1.2 Ω RDS(on) at VGS = 10 V, 42 nC total gate charge, and 570 mJ single-pulse avalanche energy-designed for high-voltage switching in offline SMPS and UPS systems.
For engineers reviewing the IRFBC40ASTRRPBF datasheet, IRFBC40ASTRRPBF pinout, IRFBC40ASTRRPBF application, or IRFBC40ASTRRPBF equivalent, key selection criteria include its 600 V blocking capability, rugged unclamped inductive switching performance, low Qgd/Qg ratio for hard-switching stability, and D2PAK thermal resistance of 1.0 °C/W junction-to-case.
Technical Context
This device employs planar vertical DMOS technology optimized for high-voltage, medium-current applications. Its gate structure delivers low Qg (42 nC) and balanced Qgs/Qgd (10 nC / 20 nC), supporting efficient drive with standard gate drivers while maintaining dV/dt immunity up to 6.0 V/ns.
The integrated body diode exhibits 431–647 ns reverse recovery time and 1.8–2.8 μC Qrr, enabling operation in topologies requiring freewheeling conduction-such as single-transistor forward converters-without external diode supplementation under defined dI/dt and temperature conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 600 V - supports 400 V AC mains-derived DC bus with ≥50 % safety margin |
| RDS(on) | 1.2 Ω @ VGS = 10 V - enables ≤45 W conduction loss at 6.2 A continuous drain current |
| Qg | 42 nC - compatible with low-power gate drivers (e.g., UCC27531) without external buffering |
| EAS | 570 mJ - withstands unclamped inductive energy in flyback or forward converter turn-off events |
| RthJC | 1.0 °C/W - allows 125 W power dissipation with ≤125 °C junction rise above 25 °C case temperature |
| dV/dt rating | 6.0 V/ns - ensures reliable operation in high-dV/dt environments without spurious turn-on |
| ID (TC = 100 °C) | 3.9 A - defines maximum continuous current under industrial ambient thermal constraints |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP6NK60ZFP | 600 V, 5.5 A, RDS(on) = 1.25 Ω, Qg = 32 nC, TO-220FP package | Lower thermal mass and higher RthJA (62 °C/W); unsuitable for >25 W continuous dissipation without forced air | Select when board space permits TO-220FP and lower gate charge is prioritized over avalanche robustness |
| IXTH6N60P | 600 V, 6.0 A, RDS(on) = 1.4 Ω, Qg = 48 nC, TO-247 package | Higher RDS(on) increases conduction loss by ~17 %; larger TO-247 footprint requires PCB rework | Select when higher peak current (IDM = 24 A) and superior heatsinking via TO-247 are required |
Compared with STP6NK60ZFP and IXTH6N60P, IRFBC40ASTRRPBF offers optimal balance of avalanche energy (570 mJ), D2PAK thermal performance (RthJC = 1.0 °C/W), and gate drive simplicity (Qg = 42 nC), making it preferred for compact, high-reliability offline SMPS where layout area and fault tolerance are critical.

FAQ
What is the maximum continuous drain current for IRFBC40ASTRRPBF at 100 °C case temperature?
The IRFBC40ASTRRPBF supports 3.9 A continuous drain current at TC = 100 °C, as specified in the Absolute Maximum Ratings table. This value reflects thermal derating from the 6.2 A rating at 25 °C case temperature, based on a linear derating factor of 1.0 W/°C and RthJC = 1.0 °C/W. Designers must ensure heatsink interface resistance and ambient conditions maintain case temperature ≤100 °C for sustained operation.
Does IRFBC40ASTRRPBF have a fully characterized body diode for synchronous rectification use?
The IRFBC40ASTRRPBF includes full characterization of its intrinsic body diode, including VSD = 1.5 V at IS = 6.2 A, trr = 431–647 ns, and Qrr = 1.8–2.8 μC at TJ = 25 °C. However, it is not optimized for synchronous rectification due to relatively high Qrr and lack of tailored soft-recovery design; external Schottky diodes or dedicated SR controllers are recommended for high-efficiency synchronous topologies.
What is the gate-source voltage rating for IRFBC40ASTRRPBF, and can it be driven directly from a 5 V microcontroller?
The IRFBC40ASTRRPBF has a ±30 V gate-source voltage rating but requires VGS ≥ 10 V for full enhancement (RDS(on) = 1.2 Ω). Driving it directly from a 5 V microcontroller will result in incomplete turn-on and excessive conduction loss, as VGS(th) ranges from 2.0 V to 4.0 V only-insufficient for low-resistance operation. A level-shifted gate driver or dedicated MOSFET driver IC is required for reliable switching.
How does the effective output capacitance (Coss eff.) of IRFBC40ASTRRPBF impact snubber design in a 480 V application?
The IRFBC40ASTRRPBF specifies Coss eff. = 48 pF across VDS = 0–480 V, representing the fixed capacitance yielding equivalent charging time as actual nonlinear Coss. This value enables accurate calculation of turn-off losses and snubber capacitor sizing-e.g., a 1 nF RC snubber with 100 Ω resistor limits peak VDS overshoot to <10 % during 6.2 A turn-off in a 480 V bus application.
Is IRFBC40ASTRRPBF suitable for use in automotive under-hood applications?
The IRFBC40ASTRRPBF operates across -55 °C to +150 °C junction temperature and meets RoHS/halogen-free requirements, but it is not AEC-Q101 qualified. While its electrical and thermal specs meet many under-hood stress conditions, Vishay does not certify IRFBC40ASTRRPBF for automotive safety-critical systems. For such applications, designers must perform full qualification per AEC-Q101 and consult Vishay's automotive-grade alternatives like SQM60N06-10L.
