Renesas 2SK1317-E

Overview

2SK1317-E from Renesas Electronics is a silicon N-channel power MOSFET designed for high-speed power switching applications. The device features a 1500V drain-to-source voltage rating, 2.5A continuous drain current capability, low drive current requirement, and a TO-3P power package suitable for high-voltage switching systems.

As part of the Renesas high-voltage MOSFET portfolio, 2SK1317-E combines high breakdown voltage, fast switching performance, and no secondary breakdown behavior for industrial power conversion designs. For engineers reviewing the 2SK1317-E datasheet, 2SK1317-E pinout, 2SK1317-E application, or 2SK1317-E equivalent, this device is widely used in switching regulators, DC-DC converters, motor drivers, industrial power supplies, and high-voltage power-control equipment.

Technical Context

In high-voltage power systems, 2SK1317-E operates as the main N-channel switching device controlling current flow through the power stage. Its 1500V drain-source voltage rating makes it suitable for circuits requiring large voltage margin, including offline switching regulators and industrial high-voltage converter topologies.

The device is designed for high-speed switching while requiring relatively low gate-drive current compared with bipolar power devices. This helps simplify gate-drive circuitry and reduce drive-stage losses in switching regulator, converter, and motor-driver applications.

2SK1317-E is commonly used in high-voltage DC-DC converters, switching power supplies, industrial motor-control equipment, power-distribution circuits, and converter platforms where voltage withstand capability and thermal design margin are critical.

Key Specifications

Pinout & Package

The 2SK1317-E pinout uses a TO-3P package structure with Gate, Drain, and Source terminals. The drain is also connected to the flange, so PCB layout and heatsink mounting must consider both electrical isolation and thermal transfer requirements.

For PCB implementation, high-voltage creepage spacing, controlled gate-drive routing, low-inductance source return, adequate heatsinking, and insulation management are important for safe and reliable operation in 1500V-class power systems.

Applications

Equivalent & Alternatives

When evaluating 2SK1317-E equivalent devices, engineers should compare breakdown voltage, continuous current rating, RDS(on), gate-drive requirements, switching speed, package style, and thermal performance.

Compared with STP3NK150Z, 2SK1317-E is optimized for established Renesas high-voltage switching designs using a TO-3P package and 1500V voltage margin. 2SK1317-E vs IXTP3N150 selection depends on package compatibility, RDS(on), switching frequency, thermal design, and sourcing continuity requirements.

Quality

2SK1317-E should be sourced as original Renesas components through traceable and controlled supply channels. Quality verification procedures may include package inspection, marking validation, solderability testing, drain-source breakdown verification, gate leakage testing, RDS(on) characterization, and incoming inspection according to industrial power-system production requirements.

Because the device operates in high-voltage switching environments, PCB creepage distance, insulation design, heatsink isolation, controlled gate-drive implementation, snubber design, and thermal management help maintain safe and reliable long-term operation. Traceable sourcing supports industrial manufacturing quality and reduces counterfeit supply-chain risk.
