Product details

Overview

IRFP460 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, 210 nC total gate charge, and repetitive avalanche rating-designed for high-voltage switch-mode power supplies, motor drives, and DC-DC converters.

For engineers reviewing the IRFP460 datasheet, IRFP460 pinout, IRFP460 application, or IRFP460 equivalent, key selection criteria include its 500 V V_DS, 280 W P_D at T_C = 25 °C, 3.5 V/ns peak diode recovery dV/dt, and isolated mounting hole enabling safe high-power thermal management.

Technical Context

The IRFP460 employs a third-generation planar vertical DMOS structure optimized for ruggedness and fast switching in hard-switched topologies. Its dynamic dV/dt rating and 960 mJ single-pulse avalanche energy support reliable operation under inductive load transients without external snubbers.

Gate drive is simplified by low threshold voltage (2.0–4.0 V) and moderate input capacitance (4200 pF), while internal source/drain inductances (L_S = 13 nH, L_D = 5 nH) are characterized to aid layout-aware switching loss estimation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	500 V - supports primary-side switching in offline SMPS up to 400 V DC bus with margin
R_DS(on)	0.27 Ω @ V_GS = 10 V - enables <2.7 W conduction loss at 10 A continuous drain current
Q_g	210 nC - determines gate driver current requirement (~21 mA avg. for 1 MHz f_sw)
I_D (continuous)	20 A @ T_C = 25 °C - defines heatsink sizing baseline for forced-air-cooled designs
E_AS	960 mJ - allows unclamped inductive switching without failure at I_AS = 20 A
R_thJC	0.45 °C/W - sets minimum thermal interface resistance needed to maintain T_J < 150 °C
dV/dt (diode)	3.5 V/ns - constrains PCB layout parasitics to avoid false turn-on during body diode commutation

Pinout & Package

IRFP460 uses the TO-247AC package with isolated central mounting hole, 3.6 mm diameter screw hole (ØP), and 15.7 mm nominal width (E). Thermal pad contour is optional per version; lead finish is uncontrolled in L1.

Pin/Terminal	Circuit Role	Design Meaning
1 (Gate)	Control electrode	Accepts 10 V logic-level drive; 29 nC Q_gs ensures predictable Miller plateau timing
2 (Drain)	High-side power terminal	Connected to heat sink via case; electrically tied to drain metallization and thermal pad
3 (Source)	Power return reference	Low-inductance path required; 13 nH internal L_S impacts gate drive loop stability
4 (Drain)	Secondary drain connection	Parallel drain path for reduced current density; improves thermal distribution across die

Key Features

Feature	Design Value
Repetitive avalanche rated	20 A I_AR, 28 mJ E_AR - enables robust operation in flyback/LLC resonant circuits with leakage inductance spikes
Isolated central mounting hole	3.6 mm ØP, 1.5° max draft - permits direct heatsink attachment without electrical shorting to drain
Fast switching	t_d(on) = 18 ns, t_f = 58 ns - reduces transition losses in 100–500 kHz SMPS designs
Dynamic dV/dt rating	3.5 V/ns - validated under worst-case diode recovery conditions to prevent spurious turn-on
Ease of paralleling	Positive R_DS(on) tempco + matched threshold - enables current sharing without external ballast resistors

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP16NF50	500 V, 16 A, R_DS(on) = 0.32 Ω, Q_g = 45 nC - lower gate charge but higher on-resistance and lower current rating	Preferred in space-constrained 15 A designs where gate drive power is critical; not suitable for 20 A continuous loads	Select when prioritizing fast switching over conduction loss, and thermal margin permits higher R_DS(on)
IXFH30N50P	500 V, 30 A, R_DS(on) = 0.15 Ω, Q_g = 160 nC - higher current, lower R_DS(on), but larger die and higher cost	Used in 25–30 A industrial UPS inverters requiring extended thermal headroom and lower conduction loss	Choose when system requires >20 A continuous current or <0.2 Ω R_DS(on) at same V_GS

Compared with STP16NF50 and IXFH30N50P, the IRFP460 delivers optimal balance of 20 A current capability, 0.27 Ω conduction resistance, and proven avalanche ruggedness for cost-sensitive 300–500 W power stages-making it a preferred choice where thermal design targets align with its 0.45 °C/W R_thJC.

FAQ

What is the maximum continuous drain current rating for IRFP460 at 100 °C case temperature?

The IRFP460 has a continuous drain current rating of 13 A at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the TO-247 package and must be used with R_thJC = 0.45 °C/W to calculate junction temperature rise. The IRFP460 maintains safe operation only if T_J remains ≤150 °C under actual operating conditions.

Does IRFP460 support avalanche operation, and what are its rated energy limits?

Yes, the IRFP460 is repetitively avalanche rated with I_AR = 20 A and E_AR = 28 mJ, and single-pulse avalanche energy E_AS = 960 mJ under defined test conditions (V_DD = 50 V, L = 4.3 mH, I_AS = 20 A). These values are measured per JEDEC standards and apply directly to the IRFP460 without derating. The IRFP460's avalanche capability is integral to its design and validated in production testing.

What is the gate-source threshold voltage range for IRFP460, and how does it affect drive requirements?

The IRFP460 has a gate-source threshold voltage V_GS(th) ranging from 2.0 V to 4.0 V at T_J = 25 °C, ensuring reliable turn-on with standard 10 V gate drivers. This range guarantees full enhancement well below typical logic-level thresholds, eliminating need for specialized gate biasing. The IRFP460 achieves specified R_DS(on) only when driven to ≥10 V, as confirmed in the Static Characteristics section of its datasheet.

How does the TO-247AC package of IRFP460 differ from TO-220 in high-power applications?

The TO-247AC package of the IRFP460 provides greater creepage distances, an isolated central mounting hole, and lower R_thJC (0.45 °C/W vs. ~1.0 °C/W for TO-220), enabling higher power dissipation (280 W vs. ~75 W) and compliance with stringent safety standards. Unlike TO-220, the IRFP460's TO-247AC allows direct heatsink attachment without electrical isolation hardware. These features make the IRFP460 suitable for commercial-industrial applications exceeding 200 W.

What is the body diode reverse recovery time (t_rr) of IRFP460, and why does it matter in bridge configurations?

The IRFP460 body diode has a reverse recovery time t_rr of 570–860 ns at T_J = 25 °C, I_F = 20 A, and dI/dt = 100 A/μs. In half-bridge or full-bridge topologies, this parameter directly impacts switching losses and EMI during dead-time commutation. A shorter t_rr reduces voltage overshoot and shoot-through risk; the IRFP460's value is optimized for hard-switched 50–200 kHz inverters where body diode conduction occurs regularly.
