Product details
Overview
SIHK185N60EF-T1GE3 from Vishay Siliconix is a 600 V, 16 A N-channel Power MOSFET in PowerPAK® 10 x 12 package with RDS(on) = 0.168 Ω (typ, VGS = 10 V), Qg = 21 nC (typ), and fast body diode (trr = 111 ns). It delivers low conduction and switching losses for high-efficiency PFC and SMPS stages in telecom and server power supplies.
For engineers reviewing the SIHK185N60EF-T1GE3 datasheet, SIHK185N60EF-T1GE3 pinout, SIHK185N60EF-T1GE3 application, or SIHK185N60EF-T1GE3 equivalent, key selection criteria include its 600 V VDS, 1.1 °C/W RthJC, avalanche-rated EAS = 24 mJ, Co(er) = 40 pF, and fast-recovery body diode optimized for hard-switched and resonant topologies.
Technical Context
This MOSFET employs Vishay's 4th-generation EF-series silicon technology, featuring reduced effective output capacitance (Co(er) = 40 pF) and low gate charge (Qg = 21 nC typ) to minimize switching loss in continuous conduction mode (CCM) PFC and LLC resonant converters. Its 1.1 °C/W junction-to-case thermal resistance enables high-power density designs without forced airflow.
The integrated fast body diode supports ZVS/ZCS transitions with trr = 111 ns (typ) and Qrr = 0.6 μC (typ) at 25 °C, while maintaining robust UIS capability (EAS = 24 mJ) and dv/dt immunity up to 100 V/ns (TJ = 125 °C).

Equivalent & Alternatives

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STW62N60M2 | 600 V, 62 A, RDS(on) = 0.065 Ω, TO-247 package, Qg = 65 nC | Higher current rating but larger footprint and higher gate drive requirement | Preferred for higher-current, lower-frequency (<50 kHz) industrial inverters where layout space permits TO-247 |
| IXFH32N60P | 600 V, 32 A, RDS(on) = 0.15 Ω, TO-247 package, Qg = 62 nC, no specified trr | Larger package, higher Qg, and unspecified body diode performance limits use in ZVS topologies | Suitable for non-resonant SMPS where fast diode recovery is not required and thermal mass is available |
Compared with STW62N60M2 and IXFH32N60P, SIHK185N60EF-T1GE3 offers superior power density (PowerPAK 10×12 vs. TO-247), lower Qg, and characterized fast body diode behavior-making it optimal for space-constrained, high-frequency PFC and resonant converter designs.

FAQ
What is the maximum continuous drain current rating for SIHK185N60EF-T1GE3 at 100 °C case temperature?
The SIHK185N60EF-T1GE3 has a continuous drain current rating of 10 A at TC = 100 °C, as specified in the Absolute Maximum Ratings table. This reflects thermal derating from its 16 A rating at 25 °C, based on a linear derating factor of 0.9 W/°C and RthJC = 1.1 °C/W. Designers must ensure heatsinking maintains TC ≤ 100 °C for sustained 10 A operation.
Does SIHK185N60EF-T1GE3 have a specified reverse recovery time (trr) for its body diode?
Yes, SIHK185N60EF-T1GE3 specifies trr = 111 ns (typical) and 222 ns (maximum) at TJ = 25 °C, IF = 9.5 A, di/dt = 100 A/μs, and VR = 400 V. This value is measured per JEDEC standard and confirms its suitability for hard-switched topologies where body diode commutation occurs, such as in totem-pole PFC and half-bridge LLC converters.
What is the gate threshold voltage range for SIHK185N60EF-T1GE3?
The gate threshold voltage VGS(th) for SIHK185N60EF-T1GE3 is specified as 3.0 V minimum to 5.0 V maximum at VDS = VGS and ID = 250 μA. This range ensures reliable turn-on with standard 10 V gate drivers while providing noise margin against spurious conduction in high-dv/dt environments typical of power converter applications.
Is SIHK185N60EF-T1GE3 suitable for avalanche operation, and what is its rated single-pulse energy?
Yes, SIHK185N60EF-T1GE3 is avalanche energy rated with EAS = 24 mJ (single pulse, test condition: VDD = 120 V, L = 28.2 mH, Rg = 25 Ω, IAS = 1.3 A). This rating validates its robustness in unclamped inductive switching events common in motor drives, welding equipment, and PFC circuits during transient overloads.
What is the thermal resistance from junction to case (RthJC) for SIHK185N60EF-T1GE3, and how does it impact heatsink design?
The SIHK185N60EF-T1GE3 has a maximum junction-to-case thermal resistance RthJC of 1.1 °C/W. This low value-enabled by its exposed-drain PowerPAK® 10 × 12 package-means that for a 100 W power dissipation scenario, the junction-to-case temperature rise is only 110 °C. Combined with its 150 °C max TJ, this allows compact heatsink solutions even in convection-cooled telecom and server applications.
