Product details
Overview
IRFP460NPBF from Vishay Siliconix is a 500 V, 20 A N-channel power MOSFET in TO-247 package, featuring RDS(on) = 0.24 Ω at VGS = 10 V, Qg = 124 nC, and 340 mJ single-pulse avalanche energy - designed for high-voltage switching in full-bridge SMPS and PFC boost stages.
For engineers reviewing the IRFP460NPBF datasheet, IRFP460NPBF pinout, IRFP460NPBF application, or IRFP460NPBF equivalent, key selection criteria include its 500 V VDS, 0.24 Ω on-resistance, 124 nC gate charge, 280 W power dissipation at TC = 25 °C, and robust 5.0 V/ns diode recovery dV/dt rating.
Technical Context
This discrete N-channel MOSFET operates as a unidirectional high-side or low-side switch in hard-switched topologies. Its design emphasizes ruggedness under repetitive avalanche stress (IAR = 20 A, EAR = 28 mJ) and fast, controlled switching via low Crss (30 pF) and well-characterized Coss eff. (200 pF).
The device integrates a body diode with trr = 550–825 ns and Qrr = 7.2–10.8 µC at IF = 20 A, enabling reliable operation in freewheeling and synchronous rectification roles where reverse recovery behavior directly impacts efficiency and EMI.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 500 V - supports DC bus voltages up to 400 V in PFC and offline SMPS without derating |
| RDS(on) | 0.24 Ω @ VGS = 10 V - enables ≤4.8 W conduction loss at 20 A continuous drain current |
| Qg | 124 nC - determines gate drive power requirement and switching speed in 100–500 kHz designs |
| EAS | 340 mJ - allows safe unclamped inductive switching at IAS = 20 A without external snubbers |
| trr | 550–825 ns - defines minimum dead-time setting to avoid shoot-through in bridge configurations |
| RthJC | 0.45 °C/W - sets thermal interface requirement for heatsink design when dissipating >100 W |
| ID (TC = 100 °C) | 13 A - defines usable current limit in enclosed industrial enclosures with limited airflow |
Pinout & Package
IRFP460NPBF uses the industry-standard TO-247 package with isolated tab (drain-connected), offering high thermal conductivity and mechanical stability for high-power mounting. Pin assignment is fixed: Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Gate (Pin 1) | Control input | Receives 10 V logic-level drive; threshold VGS(th) = 3.0–5.0 V ensures reliable turn-on with standard PWM controllers |
| Drain (Pin 2 / Tab) | High-voltage power terminal | Electrically connected to metal tab; requires insulated mounting hardware when referenced to non-ground potentials |
| Source (Pin 3) | Power return and reference node | Serves as local ground reference for gate drive; carries full load current and body diode reverse recovery charge |
Key Features
| Feature | Design Value |
|---|---|
| Low Qg/Qgd ratio | Qgd/Qg = 46 % - improves Miller immunity and reduces risk of false turn-on during high dV/dt transitions |
| Specified Coss eff. | 200 pF - enables accurate calculation of turn-off energy loss (Eoff ≈ ½ × Coss eff. × VDS²) |
| Characterized avalanche capability | 340 mJ single-pulse EAS - eliminates need for external clamping in inductive load switching |
| Enhanced dV/dt ruggedness | 5.0 V/ns peak diode recovery dV/dt - sustains operation in noisy high-di/dt environments without spurious turn-on |
| RoHS-compliant lead-free finish | SnAgCu termination - meets IPC-J-STD-020 reflow profiles up to 260 °C peak for automated assembly |
Applications
| Full-Bridge SMPS | PFC Boost Converter |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP20NM50FP | 500 V, 20 A, RDS(on) = 0.25 Ω, Qg = 95 nC, TO-220FP package | Lower thermal mass and 2.5 W lower PD; unsuitable for >100 W continuous conduction without forced air | Prefer for cost-sensitive, space-constrained 50–100 W SMPS where TO-247 mounting is impractical |
| IXFH40N50P | 500 V, 40 A, RDS(on) = 0.12 Ω, Qg = 170 nC, TO-247 package | Higher current rating but 37 % higher gate charge; requires stronger gate driver and larger heatsink | Choose when system demands >25 A peak current or lower conduction loss dominates over switching loss |
Compared with STP20NM50FP and IXFH40N50P, the IRFP460NPBF delivers optimal balance of gate drive simplicity (124 nC), thermal capability (280 W), and avalanche ruggedness (340 mJ) for 150–300 W industrial SMPS where reliability under transient stress is critical.

FAQ
What is the maximum continuous drain current for IRFP460NPBF at 100 °C case temperature?
The IRFP460NPBF supports 13 A continuous drain current at TC = 100 °C, as specified in the Absolute Maximum Ratings table. This value reflects thermal derating due to reduced heat transfer efficiency at elevated temperatures and must be validated against actual heatsink performance and ambient conditions in the final layout.
Does IRFP460NPBF have a fully characterized body diode?
Yes, the IRFP460NPBF includes full characterization of its intrinsic body diode: VSD = 1.8 V at IS = 20 A and TJ = 25 °C, trr = 550–825 ns, and Qrr = 7.2–10.8 µC. These parameters are measured under standardized conditions and enable accurate dead-time and EMI modeling in bridge topologies.
Is IRFP460NPBF RoHS-compliant and lead-free?
Yes, IRFP460NPBF is RoHS-compliant and features a lead-free (Pb-free) termination with SnAgCu plating. It meets JEDEC J-STD-020 moisture sensitivity level 1 and supports peak reflow temperatures up to 260 °C, making it compatible with standard lead-free PCB assembly processes.
What is the gate threshold voltage range for IRFP460NPBF?
The gate-source threshold voltage (VGS(th)) for IRFP460NPBF is specified as 3.0 V minimum to 5.0 V maximum at ID = 250 µA and TJ = 25 °C. This range ensures compatibility with standard 10 V gate drivers while providing margin against spurious turn-on from noise or leakage.
Can IRFP460NPBF replace IRFP460 in existing designs?
Yes, IRFP460NPBF is the lead-free, RoHS-compliant version of IRFP460 and shares identical electrical specifications, pinout, and package dimensions. The "PbF" suffix denotes Pb-free termination only; no circuit or layout changes are required when upgrading from IRFP460 to IRFP460NPBF.
