Product details
Overview
2SK1152-90L from Renesas is a silicon N-channel power MOSFET designed for high-speed switching in DC-DC converters and switching regulators. It features 500 V VDSS, 1.5 A continuous drain current, 4.0 Ω typical RDS(on) at VGS = 10 V, 10 ns rise time, and DPAK(L)-(1) surface-mount package with dual-drain configuration.
For engineers reviewing the 2SK1152-90L datasheet, 2SK1152-90L pinout, 2SK1152-90L application, or 2SK1152-90L equivalent, this device is selected for high-voltage, medium-current switching where low gate drive current, fast turn-on/turn-off, and absence of secondary breakdown are critical design requirements.
Technical Context
This MOSFET operates as a unidirectional high-side or low-side switch in hard-switched topologies. Its 500 V blocking rating supports 380 V DC bus applications, while its 20 W channel dissipation at TC = 25°C enables thermally constrained PCB layouts. The device uses planar V-groove process technology to achieve stable RDS(on) over temperature and eliminate secondary breakdown.
It integrates an intrinsic body diode with 1.0 V forward voltage at 1.5 A and 220 ns reverse recovery time-enabling synchronous rectification support in quasi-resonant or freewheeling paths. Gate charge is optimized at 20 nC (typ.) for efficient 100–500 kHz operation without excessive driver loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 500 V - Supports 380 V DC input systems with 30% safety margin |
| RDS(on) (typ.) | 4.0 Ω at ID = 1 A, VGS = 10 V - Enables <1.5 W conduction loss at rated current |
| tr / tf | 10 ns / 10 ns - Allows clean 500 kHz switching with minimal overlap loss |
| Qg (typ.) | 20 nC - Compatible with standard gate drivers (e.g., TC4427, UCC27531) without boost stages |
| VGS(off) | 2.0–3.0 V - Ensures reliable enhancement-mode turn-off with TTL/CMOS logic-level drive |
| Ciss / Coss | 160 pF / 45 pF - Low input/output capacitance reduces Miller effect and EMI generation |
| ID(pulse) | 6 A (10 µs, 1% duty) - Supports short-term overload handling in peak-current-mode controllers |
Pinout & Package
2SK1152-90L is housed in the Renesas PRSS0004ZD-A package, branded DPAK(L)-(1), a surface-mount variant of the standard DPAK with extended drain tab area for improved thermal performance (θch–c = 6.25°C/W). The package includes four terminals: two electrically connected drain leads (pins 2 and 4), one gate (pin 1), and one source (pin 3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Gate | Control terminal requiring ≤10 µA leakage; driven by 10 V logic for full enhancement |
| 2 & 4 | Drain (common) | High-voltage output node; both pins bonded internally to maximize current sharing and thermal path |
| 3 | Source | Reference node for gate drive; connects to power ground or floating return in high-side configurations |
Key Features
| Feature | Design Value |
|---|---|
| No secondary breakdown | Enables safe linear-mode operation and robustness against SOA violations in transient overload |
| Low drive current requirement | Gate threshold (VGS(off)) centered at 2.5 V allows direct microcontroller GPIO drive without level-shifting |
| Fast switching with low Qg | 20 nC total gate charge minimizes driver power loss and simplifies gate resistor selection |
| Integrated body diode | 1.0 V VDF at 1.5 A supports freewheeling in buck/boost topologies without external diode |
| Dual-drain thermal design | Pins 2 and 4 share heat load and reduce thermal resistance by ~15% vs. single-drain DPAK(S) |
Applications
| DC-DC Buck Converter | Switching Regulator Power Stage |
|---|---|
|
Use Scenario: Step-down conversion from 400 V DC bus to 12 V/2 A output in industrial power supplies. IC Role / Device Role / Timing Role: High-side main switch operating at 250 kHz with synchronous rectification. Use Value: 4.0 Ω RDS(on) limits conduction loss to 6 W max at full load; 10 ns rise time ensures <2% dead-time loss. |

IC Role / Device Role / Timing Role: Self-oscillating or PWM-controlled power switch with integrated snubberless operation. Use Value: 500 V VDSS accommodates reflected flyback voltage spikes up to 420 V without clamping. |
| Motor Drive Half-Bridge | LED Driver Switching Stage |
|

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 |
|---|---|---|---|
| STP5NK50ZFP | 500 V, 4.5 Ω RDS(on), 25 nC Qg, TO-220FP package | Through-hole mounting; higher thermal resistance (θJA = 62°C/W vs. 40°C/W for DPAK-L) | Prefer when board space permits through-hole assembly and higher peak pulse current (9 A) is required. |
| IXTP1R5N50D | 500 V, 5.0 Ω RDS(on), 16 nC Qg, TO-220 package | Higher RDS(on) but lower gate charge; no dual-drain thermal enhancement | Choose when gate drive efficiency is prioritized over conduction loss in low-duty-cycle burst-mode operation. |
Compared with STP5NK50ZFP and IXTP1R5N50D, the 2SK1152-90L delivers superior thermal performance per unit area due to its dual-drain DPAK(L)-(1) package and lower RDS(on), making it optimal for compact, surface-mounted DC-DC modules where layout density and thermal management are constrained.

FAQ
What is the maximum continuous drain current rating for the 2SK1152-90L?
The 2SK1152-90L has a continuous drain current (ID) rating of 1.5 A at TC = 25°C. This value derates linearly above 25°C case temperature, reaching zero at 150°C channel temperature. For sustained operation, thermal design must ensure case temperature remains within the safe operating area defined in the datasheet's derating curve.
Does the 2SK1152-90L have a built-in body diode, and what are its key parameters?
Yes, the 2SK1152-90L integrates a body diode with a forward voltage (VDF) of 1.0 V at IF = 1.5 A and reverse recovery time (trr) of 220 ns under specified test conditions (diF/dt = 100 A/µs, VGS = 0). This diode supports freewheeling and synchronous rectification functions without requiring external components.
Can the 2SK1152-90L be driven directly by a 3.3 V microcontroller GPIO?
No-the 2SK1152-90L requires ≥10 V gate-to-source voltage for guaranteed low RDS(on) operation. At 3.3 V, the device remains in weak inversion with high on-resistance (>100 Ω), causing excessive heating. A dedicated gate driver (e.g., TC4427) or level-shifter is required to deliver 10–15 V to the gate of the 2SK1152-90L.
What is the meaning of "-90L" in the part number 2SK1152-90L?
The "-90L" suffix identifies the specific variant within the 2SK1152 family: "90" denotes the RDS(on) grade (4.0 Ω typ.), and "L" specifies the DPAK(L)-(1) package (PRSS0004ZD-A), distinguishing it from the S-version (DPAK(S), PRSS0004ZD-C) used in 2SK1152STL-E. This suffix ensures mechanical and thermal compatibility in automated assembly.
Is the 2SK1152-90L suitable for use in automotive applications?
The 2SK1152-90L is not qualified to AEC-Q101 or automotive-grade reliability standards. Renesas explicitly states in the datasheet that its semiconductors are not designed for transportation, vehicular, or life-critical systems. For automotive use, consult Renesas' official automotive product line or qualified alternatives such as the RV1S92xx series.
