Product details

Overview

2SK1094-93 from Renesas Electronics (formerly Hitachi) is a silicon N-channel power MOSFET designed for high-speed switching in DC-DC converters and motor drive circuits. It features 60 V V_DSS, 15 A continuous drain current, and low R_DS(on) of 0.055 Ω at V_GS = 10 V, enabling efficient power control in compact industrial power stages.

For engineers reviewing the 2SK1094-93 datasheet, 2SK1094-93 pinout, 2SK1094-93 application, or 2SK1094-93 equivalent, key selection criteria include gate threshold voltage (1.0–2.0 V), 4 V logic-level drivability, body diode recovery time (135 ns), and TO-220FM package thermal performance for sustained 25 W channel dissipation.

Technical Context

This MOSFET employs a planar vertical DMOS structure optimized for fast switching with minimal gate charge. Its 0.075 Ω R_DS(on) at 4 V gate drive enables direct interface with 5 V microcontrollers without level-shifting circuitry.

Dynamic parameters-including 10 ns turn-on delay, 70 ns rise time, 180 ns turn-off delay, and 120 ns fall time-support operation up to several hundred kHz in hard-switched topologies. The integrated body diode exhibits 1.3 V forward voltage and 135 ns reverse recovery time under rated conditions.

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
IRFZ44NPBF	R_DS(on) = 0.028 Ω @ 10 V; V_GS(th) = 2–4 V; TO-220AB package (non-insulated tab)	Higher drive voltage requirement limits direct 5 V MCU interface without gate boosting	Preferred where lower conduction loss justifies added gate drive complexity and isolation hardware
STP16NF06L	R_DS(on) = 0.055 Ω @ 5 V; V_GS(th) = 1–2.5 V; TO-220FP package (full-pack, insulated)	Lower gate charge and faster switching (t_r/t_f ≈ 40/30 ns) but reduced P_ch rating (20 W)	Better suited for higher-frequency (>500 kHz) applications where thermal margin permits lower power dissipation

Compared with IRFZ44NPBF and STP16NF06L, the 2SK1094-93 offers balanced trade-offs: guaranteed 4 V drive capability, TO-220FM insulation, and 25 W channel dissipation-making it optimal for cost-sensitive, medium-frequency industrial power switches where gate simplicity and thermal reliability are prioritized over ultra-low R_DS(on) or sub-100 ns transitions.

FAQ

What is the gate threshold voltage range for the 2SK1094-93?

The 2SK1094-93 has a specified gate-to-source cutoff voltage (V_GS(off)) of 1.0–2.0 V at I_D = 1 mA and V_DS = 10 V. This low threshold enables full enhancement with 4 V gate drive, making the 2SK1094-93 compatible with standard 5 V logic outputs without external level shifting. The narrow range ensures consistent turn-on behavior across temperature and unit variation.

Can the 2SK1094-93 be used with a 3.3 V microcontroller output?

The 2SK1094-93 is not guaranteed to operate reliably with 3.3 V gate drive. Its R_DS(on) is characterized at V_GS = 4 V and 10 V, and the maximum V_GS(off) is 2.0 V. At 3.3 V, the device may remain partially enhanced, increasing conduction loss and thermal stress. For 3.3 V systems, a gate driver or logic-level MOSFET with lower V_GS(th) is recommended instead of the 2SK1094-93.

What is the maximum continuous power dissipation for the 2SK1094-93?

The 2SK1094-93 has a channel dissipation (P_ch) rating of 25 W at case temperature T_C = 25°C. This value decreases linearly with rising case temperature, reaching zero at T_C = 150°C. The thermal resistance θ_ch–c is 5.0°C/W, meaning a 25 W load generates a 125°C temperature rise above ambient-so effective heatsinking is essential to maintain safe channel temperature below 150°C for long-term reliability of the 2SK1094-93.

Does the 2SK1094-93 have an integrated body diode, and what are its characteristics?

Yes, the 2SK1094-93 includes an integral body diode rated for 15 A reverse drain current (I_DR). Its forward voltage (V_DF) is 1.3 V at I_F = 15 A and V_GS = 0, and its reverse recovery time (t_rr) is 135 ns under specified test conditions (I_F = 15 A, di_F/dt = 50 A/µs). These parameters make the 2SK1094-93 suitable for freewheeling and inductive load commutation without external diodes in many applications.

What is the package type and insulation status of the 2SK1094-93?

The 2SK1094-93 uses the TO-220FM package, which features a fully insulated metal tab. Unlike standard TO-220AB variants, the TO-220FM eliminates the need for insulating washers or thermal pads when mounted directly to a heatsink-reducing thermal resistance and assembly complexity. This construction is confirmed in the device outline diagram and mechanical drawings referenced in the original Hitachi datasheet for the 2SK1094-93.
