Product details

Overview

IRFP460LC from Vishay Siliconix is a 500 V, 20 A N-channel enhancement-mode Power MOSFET in TO-247AC package, featuring 0.27 Ω R_DS(on) at V_GS = 10 V, 120 nC total gate charge, and repetitive avalanche rating up to 20 A - designed for high-efficiency hard-switched SMPS, motor drives, and UPS inverters.

For engineers reviewing the IRFP460LC datasheet, IRFP460LC pinout, IRFP460LC application, or IRFP460LC equivalent, this device delivers verified dV/dt immunity (3.5 V/ns), low C_iss/C_oss/C_rss, enhanced ±30 V gate rating, and isolated mounting hole for thermal management in industrial power conversion designs.

Technical Context

The IRFP460LC employs planar stripe silicon technology optimized for reduced gate charge and dynamic capacitance, enabling faster switching with lower drive loss. Its rugged unclamped inductive switching capability supports 960 mJ single-pulse avalanche energy and 28 mJ repetitive avalanche energy under defined conditions.

Thermal design is supported by a maximum junction-to-case thermal resistance of 0.45 °C/W and a flat, greased case-to-sink resistance of 0.24 °C/W. The body diode exhibits 570–860 ns reverse recovery time and 6.6–9.9 μC Q_rr at 25 °C, making it suitable for freewheeling in non-synchronous topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	500 V - supports DC bus voltages up to 400 V RMS in offline SMPS and motor drive applications
R_DS(on) @ V_GS = 10 V	0.27 Ω - enables <2.7 W conduction loss at 10 A continuous drain current
Q_g	120 nC - reduces gate driver power demand and allows use of lower-cost drivers in 50–100 kHz converters
I_D @ T_C = 25 °C	20 A - rated for sustained operation with heatsink; derates linearly to 12 A at 100 °C case temperature
E_AS	960 mJ - provides robustness against inductive turn-off transients without external snubbers
dV/dt Rating	3.5 V/ns - ensures reliable operation in high-dV/dt environments such as bridge-leg commutation
T_J Range	−55 to +150 °C - qualified for industrial and extended-temperature embedded power systems

Pinout & Package

IRFP460LC uses the TO-247AC package (JEDEC-compliant, high-voltage variant) with isolated central mounting hole, flat metal tab for heatsinking, and three leads: Gate (lead 1), Drain (leads 2 and 4), Source (lead 3). Thermal pad contour is optional per version.

Pin/Terminal	Circuit Role	Design Meaning
1 (Gate)	Control electrode	Accepts 10 V logic-level gate drive; ±30 V max rating prevents gate oxide damage during transient coupling
2 & 4 (Drain)	Main high-side current path	Electrically tied internally; dual-drain configuration improves current sharing and reduces lead inductance (L_D = 5.0 nH)
3 (Source)	Reference node / return path	Serves as local ground reference for gate drive; internal source inductance L_S = 13 nH affects diode recovery behavior

Key Features

Feature	Design Value
Ultra-low gate charge	Q_g = 120 nC enables <1.2 W gate drive loss at 100 kHz with 12 V drive - critical for high-frequency SMPS efficiency
Enhanced V_GS rating	±30 V absolute maximum gate-source voltage improves noise immunity and eliminates need for gate clamping in noisy industrial environments
Repetitive avalanche rated	Rated for I_AR = 20 A and E_AR = 28 mJ - supports reliable operation in unclamped inductive loads without derating
Reduced dynamic capacitances	C_iss = 3600 pF, C_oss = 440 pF, C_rss = 39 pF - lowers switching losses and improves ZVS/ZCS feasibility in resonant topologies
Isolated mounting hole	Central screw-mount hole electrically isolated from drain - allows direct heatsink attachment without insulating hardware or thermal pads

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel high-voltage power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP16NF50	R_DS(on) = 0.32 Ω, Q_g = 100 nC, V_DS = 500 V, TO-220 package	Lacks isolated mounting hole and avalanche rating; lower thermal capability (R_thJC = 1.0 °C/W)	Acceptable for lower-power (<500 W), non-avalanche-critical designs where TO-220 footprint suffices
IXFH30N50P	R_DS(on) = 0.18 Ω, Q_g = 135 nC, V_DS = 500 V, TO-247 package	Higher gate charge increases driver loss; no specified dV/dt rating or body diode Q_rr data	Better conduction efficiency but requires stronger gate driver; less validated for high-dV/dt bridge operation

Compared with STP16NF50 and IXFH30N50P, the IRFP460LC offers balanced trade-offs: superior thermal interface (isolated TO-247), verified dV/dt immunity, and documented avalanche performance - making it preferred for industrial-grade 1–3 kW power stages where reliability under transient stress is mandatory.

FAQ

What is the maximum continuous drain current rating for IRFP460LC at 100 °C case temperature?

The IRFP460LC is rated for 12 A continuous drain current at T_C = 100 °C, with linear derating from 20 A at 25 °C using a factor of 2.2 W/°C. This reflects its thermal limit under real heatsink conditions and must be validated with actual board layout and airflow.

Does IRFP460LC have a specified body diode reverse recovery charge (Q_rr)?

Yes, the IRFP460LC specifies Q_rr = 6.6–9.9 μC at T_J = 25 °C, I_F = 20 A, and dI/dt = 100 A/μs. This value is critical for estimating freewheeling losses and EMI in non-synchronous rectification circuits.

Is IRFP460LC pin-compatible with standard TO-247 MOSFETs like IRFP460?

Yes, IRFP460LC shares identical TO-247AC mechanical dimensions and pinout (Gate–Drain–Source–Drain) with IRFP460, but features improved gate charge, dV/dt rating, and avalanche capability - making it a direct upgrade path without PCB changes.

What is the gate-source threshold voltage range for IRFP460LC?

The IRFP460LC has a V_GS(th) range of 2.0 V to 4.0 V at V_DS = V_GS and I_D = 250 μA. This ensures reliable turn-on with standard 10 V gate drivers while maintaining noise margin against false triggering.

Can IRFP460LC be used in avalanche mode for energy absorption?

Yes, IRFP460LC is explicitly repetitive avalanche rated: I_AR = 20 A and E_AR = 28 mJ under defined pulse conditions. Its single-pulse avalanche energy is 960 mJ - enabling safe operation in inductive switching without external protection.
