Product details
Overview
2SK1636STR-E from Renesas Electronics is a silicon N-channel MOSFET designed for high-speed power switching in DC-DC converters and switching regulators. It delivers 15 A continuous drain current, 250 V drain-to-source breakdown voltage, and a typical RDS(on) of 0.22 Ω at VGS = 10 V, enabling efficient low-loss operation in compact power stages.
For engineers reviewing the 2SK1636STR-E datasheet, 2SK1636STR-E pinout, 2SK1636STR-E application, or 2SK1636STR-E equivalent, key selection criteria include its LDPAK(S)-(1) package thermal performance, 110 ns turn-off delay time, body diode reverse recovery time of 400 ns, and suitability for high-frequency synchronous rectification and industrial SMPS designs.
Technical Context
This MOSFET employs a planar vertical DMOS structure with no secondary breakdown limitation, supporting robust pulsed operation up to 60 A (10 µs, 1% duty). Its gate threshold voltage range of 2.0–3.0 V ensures reliable TTL/CMOS-level drive compatibility while maintaining noise immunity.
The integrated body diode exhibits 1.0 V forward voltage at 15 A and 400 ns reverse recovery time under di/dt = 100 A/µs, making it suitable for freewheeling paths where controlled reverse recovery is critical to minimize switching loss and EMI.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 250 V - Supports input rails up to 200 V DC with safety margin in offline or industrial DC-DC applications. |
| ID (continuous) | 15 A at TC = 25°C - Enables use in medium-power switch-mode supplies without forced air cooling. |
| RDS(on) | 0.22 Ω typ. @ VGS = 10 V - Delivers ≤ 49 W conduction loss at 15 A, reducing heatsink requirements. |
| td(off) | 110 ns - Allows stable operation at switching frequencies up to ~500 kHz in hard-switched topologies. |
| Ciss | 1250 pF - Determines gate drive energy requirement (~6.25 µC at 10 V), influencing driver IC selection. |
| trr | 400 ns - Limits usable frequency in asynchronous flyback or buck converters due to diode tail current. |
| Pch | 75 W @ TC = 25°C - Defines maximum steady-state power dissipation before thermal derating applies. |
Pinout & Package
2SK1636STR-E uses the LDPAK(S)-(1) surface-mount package (Renesas code PRSS0004AE-B), featuring enhanced thermal resistance (θch–c = 1.67°C/W) and optimized leadframe layout for high-current PCB routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Control terminal requiring ≤ ±10 µA leakage; driven by 10 V logic for full enhancement. |
| 2 (D) | Drain | Main high-side power node; electrically connected to exposed drain pad for thermal and current path integrity. |
| 3 (S) | Source | Reference node for gate drive; tied to power ground in low-side configurations. |
| 4 (D) | Drain (redundant) | Second drain connection for parallel current handling and improved thermal spreading across PCB copper. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXTP15N25P | Higher RDS(on) (0.32 Ω), TO-220 package, 250 V rating | Larger footprint, higher thermal resistance (θJA = 62°C/W vs. LDPAK's 40°C/W) | Preferred where through-hole assembly or legacy board compatibility is required. |
| IRF640NPBF | Lower VDSS (200 V), similar RDS(on) (0.18 Ω), TO-220FP package | Not rated for 200 V DC bus applications; unsuitable for industrial offline inputs | Select only for sub-160 V DC systems where cost sensitivity outweighs voltage margin needs. |
Compared with IXTP15N25P and IRF640NPBF, the 2SK1636STR-E provides superior thermal performance in surface-mount layouts, tighter VGS(off) control for predictable turn-on, and guaranteed 250 V blocking-critical for reliability in unregulated industrial power rails.

FAQ
What is the maximum continuous drain current rating for the 2SK1636STR-E?
The 2SK1636STR-E is rated for 15 A continuous drain current at case temperature TC = 25°C. This rating decreases with rising case temperature per the derating curve in the datasheet, reaching approximately 7.5 A at TC = 100°C. The 2SK1636STR-E must be mounted on a PCB with adequate copper area to maintain thermal performance within specification.
Does the 2SK1636STR-E have a built-in body diode, and what are its key parameters?
Yes, the 2SK1636STR-E integrates a body diode rated for 15 A reverse current with a forward voltage of 1.0 V at IF = 15 A and reverse recovery time of 400 ns under di/dt = 100 A/µs. This diode is intrinsic to the MOSFET structure and enables freewheeling operation in buck or flyback topologies without an external diode. The 2SK1636STR-E body diode characteristics are fully specified in the Electrical Characteristics table.
What package type does the 2SK1636STR-E use, and how does it differ from the 2SK1636L-E variant?
The 2SK1636STR-E uses the LDPAK(S)-(1) surface-mount package (Renesas code PRSS0004AE-B), while the 2SK1636L-E uses LDPAK(L) (PRSS0004AE-A). Both share identical electrical specs, but the LDPAK(S)-(1) has a smaller outline and lower mass (1.30 g vs. 1.40 g), optimized for automated pick-and-place and higher-density layouts. The 2SK1636STR-E designation confirms tape-and-reel packaging for SMT production.
Is the 2SK1636STR-E suitable for automotive applications?
No-the 2SK1636STR-E is classified as a Standard-grade Renesas product intended for industrial, office, and communications equipment per Quality Grade documentation. It is not qualified to AEC-Q101 or rated for automotive temperature ranges (–40°C to +150°C junction). For automotive use, Renesas offers separate AEC-Q101-qualified MOSFETs; the 2SK1636STR-E should not be deployed in safety-critical or vehicle-mounted systems.
What is the gate threshold voltage range for the 2SK1636STR-E, and how does it affect drive circuit design?
The 2SK1636STR-E has a gate-to-source cutoff voltage VGS(off) range of 2.0–3.0 V, measured at ID = 1 mA. This ensures full enhancement at VGS ≥ 10 V while allowing reliable turn-off with logic-level gate drive. Designers must ensure gate drive voltage exceeds 3.0 V to avoid linear-mode operation and thermal runaway; the 2SK1636STR-E performs optimally with 10–15 V gate drive in switching applications.
