Product details
Overview
2SK1094-E 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 VDSS, 15 A continuous drain current, 0.055 Ω RDS(on) at VGS = 10 V, 4 V gate threshold compatibility with 5 V logic, and TO-220FM package with isolated tab.
For engineers reviewing the 2SK1094-E datasheet, 2SK1094-E pinout, 2SK1094-E application, or 2SK1094-E equivalent, key selection criteria include its low on-resistance at 4 V gate drive, fast switching times (td(on) = 10 ns, tf = 120 ns), body diode recovery (trr = 135 ns), and thermal resistance (θch–c = 5.0 °C/W).
Technical Context
The 2SK1094-E employs a planar vertical DMOS structure optimized for low conduction loss and fast turn-on/turn-off. Its gate threshold voltage range (1.0–2.0 V) enables reliable enhancement-mode operation with TTL/CMOS-compatible 5 V drive, while the integrated body diode supports freewheeling in inductive loads without external components.
Thermal design is constrained by channel temperature limits (Tch = 150 °C) and transient thermal impedance γS(t), where 1 ms pulses allow up to 25 W dissipation at TC = 25 °C but derate linearly above 25 °C case temperature per the published Pch vs. TC curve.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 60 V - Maximum blocking voltage before avalanche; suitable for 48 V bus systems with margin |
| ID (continuous) | 15 A - Continuous drain current at TC = 25 °C; limited by package thermal resistance |
| RDS(on) | 0.055 Ω (typ) at VGS = 10 V - Conduction loss of 6.6 W at 15 A; enables high-efficiency power stages |
| VGS(th) | 1.0–2.0 V - Ensures full enhancement with 4–5 V gate drive; avoids partial turn-on in logic-level systems |
| trr | 135 ns - Body diode reverse recovery time; critical for synchronous rectification and snubberless flyback designs |
| θch–c | 5.0 °C/W - Channel-to-case thermal resistance; defines heatsink requirement for steady-state operation |
| Ciss | 860 pF - Input capacitance at VDS = 10 V; determines gate drive strength needed for 10 ns turn-on |
Pinout & Package
Package: TO-220FM - Full-molded variant with electrically isolated metal tab (drain-connected), enabling direct mounting to heatsink without insulator.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Gate) | Control terminal | Receives voltage-controlled signal; requires ≤10 µA leakage (IGSS ≤ ±10 µA) to sustain bias |
| 2 (Drain) | High-side power output | Connected to heatsink tab; carries full load current and withstands 60 V transients |
| 3 (Source) | Power return reference | Common node for gate drive return and current sensing; referenced to system ground in low-side switch config |
Key Features
| Feature | Design Value |
|---|---|
| 4 V gate drive compatibility | Operates fully enhanced with standard 5 V logic; eliminates need for level-shifting or gate boosters |
| Low RDS(on) at low VGS | 0.075 Ω (max) at VGS = 4 V - reduces conduction loss in 3.3 V/5 V microcontroller-driven systems |
| Fast switching speed | 10 ns turn-on delay + 70 ns rise time - minimizes transition losses in >100 kHz SMPS topologies |
| Integrated body diode | 15 A rated IDR with 1.3 V forward drop - supports unidirectional inductive energy recirculation without external diode |
| TO-220FM isolation | Electrically isolated metal tab - allows direct heatsink mounting with no insulating washer or thermal pad required |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP16NF06 | 60 V VDSS, 16 A ID, 0.055 Ω RDS(on) at VGS = 10 V; TO-220 package (non-isolated tab) | Requires insulated mounting hardware; lacks 4 V gate drive optimization | Preferred when higher peak current margin is needed and heatsink isolation is managed externally |
| IRFZ44NPBF | 55 V VDSS, 49 A ID, 0.028 Ω RDS(on); TO-220AB package, non-isolated tab | Lower voltage rating limits use to ≤36 V systems; higher current rating increases gate charge | Selected for cost-sensitive 24 V motor drives where 55 V margin suffices and gate driver can supply 71 nC Qg |
Compared with STP16NF06 and IRFZ44NPBF, the 2SK1094-E uniquely combines 4 V gate drive capability, TO-220FM isolated tab, and 135 ns body diode recovery-making it optimal for space-constrained, logic-level-driven 48 V power stages requiring minimal external components.

FAQ
What is the maximum gate-to-source voltage rating for the 2SK1094-E?
The 2SK1094-E has a maximum gate-to-source voltage rating (VGSS) of ±20 V. This specification defines the absolute limit for gate bias integrity: exceeding ±20 V risks permanent gate oxide breakdown. The device operates reliably within –16 V to +16 V under normal conditions, with IGSS ≤ ±10 µA at those extremes. Always observe this rating during ESD handling, gate driver design, and transient suppression.
Can the 2SK1094-E be used as a direct replacement for the 2SK971 in existing designs?
No, the 2SK1094-E is not a direct replacement for the 2SK971. Although both are Hitachi N-channel MOSFETs in TO-220FM packages, the 2SK971 has VDSS = 50 V and RDS(on) = 0.075 Ω (at VGS = 10 V), while the 2SK1094-E offers higher 60 V rating and lower 0.055 Ω RDS(on). Layout changes may be needed due to differing safe operating area curves and thermal impedance profiles cited in the 2SK1094-E datasheet.
Does the 2SK1094-E have an integrated body diode, and what are its key parameters?
Yes, the 2SK1094-E includes an integrated body diode rated for 15 A reverse drain current (IDR). Its forward voltage is 1.3 V at IF = 15 A and VGS = 0, and its reverse recovery time (trr) is 135 ns under specified test conditions (diF/dt = 50 A/µs). These values enable efficient freewheeling in inductive switching applications without adding external diodes.
What is the thermal resistance from channel to case (θch–c) for the 2SK1094-E?
The 2SK1094-E has a channel-to-case thermal resistance (θch–c) of 5.0 °C/W, measured at TC = 25 °C. This value applies to steady-state conduction and is used to calculate junction temperature rise: Tj = TC + (Pch × 5.0). Transient thermal impedance varies with pulse width, as shown in the normalized γS(t) curve on page 4 of the original datasheet.
Is the TO-220FM package of the 2SK1094-E electrically isolated?
Yes, the TO-220FM package used by the 2SK1094-E features an electrically isolated metal tab. Pin 2 (Drain) connects internally to the tab, but the molding compound provides dielectric isolation between the tab and the leads. This allows direct mechanical mounting to a grounded heatsink without requiring insulating hardware-reducing thermal interface resistance and assembly complexity.
