Product details

Overview

IRFB17N50LPBF from Vishay Siliconix is a 500 V, 16 A N-channel power MOSFET in TO-220AB package, featuring R_DS(on) = 0.28 Ω at V_GS = 10 V, Q_g = 130 nC, and low trr (170–250 ns) for high-frequency switching in SMPS and ZVS circuits.

For engineers reviewing the IRFB17N50LPBF datasheet, IRFB17N50LPBF pinout, IRFB17N50LPBF application, or IRFB17N50LPBF equivalent, this device is selected for robust avalanche energy handling (E_AS = 390 mJ), fast soft-recovery body diode, and stable R_DS(on) over temperature in industrial power converters.

Technical Context

This MOSFET employs planar silicon technology with fully characterized avalanche capability and dynamic dV/dt ruggedness up to 13 V/ns. Its gate charge profile (Q_gs = 33 nC, Q_gd = 59 nC) supports predictable turn-on/turn-off timing in hard-switched topologies.

The device integrates a low-loss body diode with reverse recovery charge Q_rr = 470–710 nC (T_J = 25 °C) and exhibits linear SOA behavior up to 10 μs pulses, enabling reliable operation in unclamped inductive switching and PWM inverters.

Key Specifications

V_DS	500 V - Withstands DC bus voltages up to 400 V in 400 V-class SMPS designs with margin.
R_DS(on)	0.28 Ω max at V_GS = 10 V - Enables <1.8 W conduction loss at 16 A continuous drain current.
Q_g	130 nC - Requires moderate gate drive strength; compatible with standard 1–2 A peak gate drivers.
E_AS	390 mJ single-pulse - Supports unclamped inductive switching without external snubbers in UPS and motor drives.
t_rr	170–250 ns - Soft recovery reduces voltage overshoot and EMI in high-dI/dt (>347 A/μs) applications.
R_thJC	0.56 °C/W - Allows 220 W power dissipation at T_C = 25 °C with minimal heatsink requirement.

Pinout & Package

TO-220AB package with isolated tab (drain-connected), through-hole mounting, and 3-pin vertical configuration. Standard lead spacing (2.54 mm) and screw-mount compatibility (6-32/M3).

Pin/Terminal	Circuit Role	Design Meaning

Key Features

Feature	Design Value
Low Q_g/Q_gd ratio	Q_gd/Q_g ≈ 45 % - Improves Miller immunity and enables stable operation at high dV/dt rates.
Fully characterized C_iss/C_oss/C_rss	C_iss = 2760 pF, C_rss = 37 pF - Enables accurate snubber design and predictive switching loss modeling.
Soft-recovery body diode	trr = 170–250 ns, Q_rr = 470–710 nC - Reduces switching stress and eliminates need for external anti-parallel diodes in bridge legs.
Avalanche-rated	E_AS = 390 mJ, I_AR = 16 A - Permits operation in non-zero-current-switching (NZCS) and fault-tolerant topologies without derating.

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	R_DS(on) = 0.30 Ω, Q_g = 110 nC, E_AS = 290 mJ, TO-220FP package (shorter leads)	Lower gate charge but reduced avalanche energy; less suitable for unclamped inductive loads.	Preferable where gate drive current is limited and avalanche stress is minimal.
IXTH16N50L	R_DS(on) = 0.27 Ω, Q_g = 145 nC, E_AS = 420 mJ, TO-247AC package (higher thermal performance)	Higher thermal resistance to ambient but superior R_thJC (0.45 °C/W); larger footprint.	Preferred for >250 W continuous conduction mode designs requiring extended thermal margin.

Compared with STP16NF50 and IXTH16N50L, the IRFB17N50LPBF offers balanced trade-offs: higher avalanche robustness than STP16NF50 and lower gate drive demand than IXTH16N50L, while maintaining TO-220AB compatibility for legacy board layouts.

FAQ

What is the maximum continuous drain current rating for IRFB17N50LPBF at 100 °C case temperature?

The IRFB17N50LPBF has a continuous drain current rating of 11 A at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the TO-220AB package and ensures junction temperature remains within the -55 °C to +150 °C operating range under sustained load conditions. The IRFB17N50LPBF maintains stable R_DS(on) performance across this temperature span.

Does IRFB17N50LPBF have a fully rated avalanche capability, and what is its single-pulse energy limit?

Yes, the IRFB17N50LPBF is fully characterized for repetitive and single-pulse avalanche operation. Its single-pulse avalanche energy (E_AS) is rated at 390 mJ under test conditions of L = 3.0 mH, R_g = 25 Ω, and I_AS = 16 A. This specification is validated per Figure 12 in the official Vishay datasheet S21-0340-Rev. C, confirming robustness in unclamped inductive switching events. The IRFB17N50LPBF supports such operation without degradation when applied within datasheet limits.

What is the typical reverse recovery time (trr) of the body diode in IRFB17N50LPBF, and how does it vary with temperature?

The IRFB17N50LPBF body diode exhibits a typical reverse recovery time (t_rr) of 170–250 ns at T_J = 25 °C and 220–330 ns at T_J = 125 °C, measured at I_F = 16 A and dI/dt = 100 A/μs. This soft recovery behavior minimizes voltage spikes and EMI generation during commutation. The IRFB17N50LPBF's t_rr increase with junction temperature is consistent with silicon physics and is fully characterized in the datasheet's "Drain-Source Body Diode Characteristics" section.

Is IRFB17N50LPBF RoHS-compliant, and what does the 'PbF' suffix indicate?

Yes, IRFB17N50LPBF is RoHS-compliant. The 'PbF' suffix denotes lead (Pb)-free terminations, confirming compliance with EU RoHS Directive 2011/65/EU and related regional regulations. Vishay explicitly states this in the Ordering Information section of datasheet S21-0340-Rev. C, and the device carries no exemptions for lead content. The IRFB17N50LPBF meets material categorization requirements defined in Vishay document 99912.

What is the gate-source threshold voltage (V_GS(th)) range for IRFB17N50LPBF, and how does it affect drive circuit design?

The IRFB17N50LPBF has a gate-source threshold voltage (V_GS(th)) range of 3.0 V to 5.0 V at I_D = 250 μA, per the datasheet's Static Specifications table. This confirms standard-level (not logic-level) gate drive compatibility, requiring ≥10 V for full enhancement. Drive circuits must ensure stable V_GS ≥ 12 V to maintain low R_DS(on) and avoid linear-mode operation. The IRFB17N50LPBF's V_GS(th) stability over temperature supports predictable turn-on behavior in wide-temperature-range applications.
