Product details
Overview
IRFBC40STRLPBF from Vishay Siliconix is a 600 V, 6.2 A N-channel surface-mount power MOSFET in D2PAK (TO-263) package, featuring 1.2 Ω RDS(on) at VGS = 10 V, 60 nC total gate charge, and full avalanche rating-designed for high-voltage flyback and offline SMPS primary-side switching.
For engineers reviewing the IRFBC40STRLPBF datasheet, IRFBC40STRLPBF pinout, IRFBC40STRLPBF application, or IRFBC40STRLPBF equivalent, key selection criteria include its 150 °C junction rating, dynamic dV/dt capability of 3.0 V/ns, rugged unclamped inductive switching performance (EAS = 570 mJ), and compatibility with standard D2PAK PCB footprints and thermal pads.
Technical Context
This third-generation planar vertical MOSFET uses a robust silicon process optimized for high-voltage hard-switching. Its gate threshold voltage (2.0–4.0 V) ensures reliable turn-on with standard 10 V gate drivers, while low Crss (30 pF) and controlled Qgd/Qg ratio support stable high-speed operation under high dV/dt stress.
The device integrates a fast-recovery body diode (trr = 450–940 ns, Qrr = 3.8–7.9 μC) and exhibits linear SOA behavior up to 100 °C case temperature-enabling use in continuous conduction mode (CCM) PFC and resonant LLC half-bridge topologies without external snubbers.

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, 6 A, RDS(on) = 1.2 Ω, but uses SuperMESH™ process with higher Ciss (1500 pF) | Higher gate charge (75 nC) increases driver loss; less suitable for >100 kHz operation | Prefer IRFBC40STRLPBF where switching speed and dV/dt immunity are critical |
| FQP6N60C | 600 V, 6.2 A, RDS(on) = 1.3 Ω, but lacks specified EAS rating and dV/dt test data | No documented avalanche ruggedness-requires external clamping in inductive loads | Choose IRFBC40STRLPBF when unclamped inductive switching reliability is mandatory |
Compared with STP6NK60ZFP and FQP6N60C, IRFBC40STRLPBF delivers superior dynamic dV/dt immunity (3.0 V/ns), guaranteed single-pulse avalanche energy (570 mJ), and lower Qgd for reduced Miller-induced switching delay-making it preferred for high-reliability offline SMPS where layout parasitics cannot be fully controlled.

FAQ
What is the maximum continuous drain current for IRFBC40STRLPBF at 100 °C case temperature?
The IRFBC40STRLPBF 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 and is validated under standard PCB mounting conditions (1"² FR-4). Designers must verify actual case temperature using thermal simulation or measurement to ensure safe operation within this limit. The IRFBC40STRLPBF's 1.0 °C/W RthJC enables predictable junction-to-case heat transfer.
Does IRFBC40STRLPBF have a fully rated avalanche capability, and what does that mean for circuit design?
Yes, IRFBC40STRLPBF is fully avalanche rated with a single-pulse EAS of 570 mJ and repetitive IAR of 6.2 A. This means the device can safely absorb inductive energy during switching events-such as transformer leakage spikes in flyback converters-without requiring external snubbers or clamps. For reliable operation, designers must ensure pulse width and duty cycle stay within limits defined by maximum junction temperature (see Figure 11). The IRFBC40STRLPBF's ruggedness simplifies protection circuitry in cost-sensitive power supplies.
What is the gate threshold voltage range for IRFBC40STRLPBF, and how does it affect drive requirements?
The IRFBC40STRLPBF has a gate-source threshold voltage (VGS(th)) range of 2.0 V to 4.0 V at TJ = 25 °C. This ensures reliable turn-on with standard 10 V gate drivers while preventing accidental activation from noise below 2 V. Because the device is not a logic-level MOSFET, it requires ≥8 V to achieve near-minimum RDS(on); operation at 5 V yields significantly higher on-resistance. The IRFBC40STRLPBF's 8.3 nC Qgs supports fast turn-on with moderate gate resistance, minimizing switching losses in high-frequency designs.
Can IRFBC40STRLPBF be used in place of IRFBC40L, and what are the mechanical differences?
No, IRFBC40STRLPBF and IRFBC40L are not interchangeable due to fundamental package differences: IRFBC40STRLPBF uses the surface-mount D2PAK (TO-263) package, while IRFBC40L uses the through-hole I2PAK (TO-262). The D2PAK has a smaller footprint and relies on PCB copper for thermal dissipation, whereas the I2PAK offers higher mechanical stability and different lead geometry. Substituting one for the other requires PCB redesign. The IRFBC40STRLPBF is supplied in tape-and-reel format (TRLPBF suffix), confirming its SMT orientation.
What is the peak diode recovery dV/dt rating for IRFBC40STRLPBF, and why is it important?
The IRFBC40STRLPBF has a peak diode recovery dV/dt rating of 3.0 V/ns, measured under specified test conditions (VGS = 10 V, ISD ≤ 6.2 A, dI/dt ≤ 80 A/μs). This parameter quantifies the device's immunity to false turn-on during rapid voltage transients across the drain-source terminals-critical in hard-switched topologies where body diode commutation occurs. Exceeding this rating risks shoot-through or oscillation. The IRFBC40STRLPBF's 3.0 V/ns value exceeds typical industry benchmarks, enabling robust operation in compact, high-density power converters without added gate resistors or RC networks.
