Product details
Overview
2SK2934-92-E from Renesas is a silicon N-channel power MOSFET designed for high-speed switching in DC-DC converters and motor drive circuits, featuring RDS(on) = 0.026 Ω (typ.) at VGS = 10 V, VDSS = 60 V, ID = 25 A, and gate threshold voltage VGS(off) = 1.5–2.5 V.
For engineers reviewing the 2SK2934-92-E datasheet, 2SK2934-92-E pinout, 2SK2934-92-E application, or 2SK2934-92-E equivalent, key selection criteria include low on-resistance at 4 V gate drive, fast switching times (td(on) = 10 ns, tf = 150 ns), and TO-220CFM package thermal performance for industrial power stages.
Technical Context
This MOSFET employs a planar vertical DMOS structure optimized for low conduction loss and controlled switching transients. Its 4 V gate drive compatibility enables direct interfacing with 5 V logic controllers without level-shifting, while the integrated body diode supports synchronous rectification and freewheeling in buck and half-bridge topologies.
The device operates within a channel temperature range of –55°C to +150°C and delivers 34 mJ avalanche energy (Tch = 25°C, Rg ≥ 50 Ω), supporting robust operation under inductive load switching and transient overvoltage conditions.
Key Specifications

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 |
|---|---|---|---|
| STP60NF06 | RDS(on) = 0.018 Ω @ 10 V but VDSS = 60 V same; Ciss = 1400 pF (vs. 740 pF); TO-220FP package (non-insulated tab) | Higher gate charge increases drive loss at >200 kHz; non-insulated tab requires isolation washer in grounded-source layouts | Select when lower conduction loss dominates over switching loss and thermal interface permits non-insulated mounting |
| IRFZ44NPBF | RDS(on) = 0.028 Ω @ 10 V; VDSS = 55 V (lower margin); tf = 60 ns (faster) but EAR not specified | Limited to ≤40 V bus systems; lacks documented avalanche capability for unclamped inductive switching | Select for cost-sensitive 24 V motor drives where avalanche stress is absent and faster fall time improves light-load efficiency |
Compared with STP60NF06 and IRFZ44NPBF, the 2SK2934-92-E provides balanced trade-offs: lower Ciss than STP60NF06 for reduced drive loss, higher VDSS margin than IRFZ44NPBF, and guaranteed avalanche ruggedness essential for industrial motor control and UPS applications.

FAQ
What is the maximum continuous drain current rating for the 2SK2934-92-E?
The 2SK2934-92-E has a continuous drain current rating of 25 A at case temperature Tc = 25°C. Derating applies above this temperature per the published thermal curve-e.g., ~12.5 A at Tc = 100°C. This rating assumes proper heatsinking and is validated under pulse test conditions with no secondary breakdown limitations reported in the datasheet for the 2SK2934-92-E.
Does the 2SK2934-92-E support 4 V gate drive in practical applications?
Yes, the 2SK2934-92-E is explicitly characterized for 4 V gate drive: RDS(on) = 0.045 Ω (typ.) at ID = 15 A and VGS = 4 V. Its VGS(off) range of 1.5–2.5 V ensures full enhancement with margin, making it compatible with standard 5 V logic outputs without external level shifters-confirmed in the official 2SK2934-92-E datasheet Rev. 4.00.
What is the avalanche energy rating of the 2SK2934-92-E and under what conditions is it specified?
The 2SK2934-92-E is rated for 34 mJ single-pulse avalanche energy (EAR) at channel temperature Tch = 25°C with gate resistance Rg ≥ 50 Ω. This value is measured using the standardized avalanche test circuit defined in the datasheet and reflects ruggedness under unclamped inductive switching-critical for motor drive and relay-driving applications where the 2SK2934-92-E may encounter stored inductive energy.
Is the 2SK2934-92-E pin-compatible with other TO-220CFM MOSFETs?
The 2SK2934-92-E uses the TO-220CFM package (RENESAS code PRSS0003AE-A) with standard 3-pin layout (G-D-S, left-to-right when tab facing outward). While mechanical footprint matches generic TO-220CFM devices, electrical characteristics-including RDS(on), Qg, and avalanche rating-are unique to the 2SK2934-92-E. No pin-compatible replacements are documented; substitution requires full electrical validation per application requirements.
What is the typical body diode forward voltage of the 2SK2934-92-E and how is it used in circuit design?
The 2SK2934-92-E body diode exhibits VDF = 0.95 V (typ.) at IF = 25 A and VGS = 0. This parameter directly impacts conduction loss during freewheeling phases in buck, flyback, and H-bridge topologies. Designers use this value to calculate diode conduction loss and assess thermal impact-especially critical in high-duty-cycle or high-current applications where the 2SK2934-92-E body diode operates without external parallel diodes.
