EKI10300

Overview

The EKI10300 is a single N-channel Trench Power MOSFET manufactured by Sanken Electric Co., Ltd. It features a 100 V drain-to-source breakdown voltage and a continuous drain current of 34 A at 25 °C case temperature. The device achieves a maximum static drain-to-source on-resistance of 28.8 mΩ at VGS = 10 V and ID = 17.1 A, with a typical value of 20.2 mΩ. Total gate charge is specified as 36.5 nC at VGS = 10 V and 16.9 nC at VGS = 4.5 V. The component utilizes a TO-220-3L package and supports a maximum operating junction temperature of 150 °C.

Feature Summary

• Capable of operation with a 4.5 V gate drive voltage for low-side switching applications
• Features low total gate charge to enable high-speed switching performance
• Includes an integrated body diode with defined reverse recovery characteristics

Applications

• DC-DC converters
• Synchronous rectification circuits
• General power supplies

Procurement Notes

Verify the specific revision number (e.g., Rev.1.4) against the manufacturer's official documentation before procurement. Confirm that the TO-220-3L physical dimensions match the target PCB footprint. Ensure the design accounts for the derating curves provided in the datasheet to maintain safe operating area limits under actual thermal conditions.

Selection Notes

Select this component when a 100 V rating and 34 A continuous current capability are required. Evaluate the thermal resistance parameters to ensure adequate heat sinking for the intended power dissipation levels. Consider the 4.5 V gate drive compatibility if interfacing with standard logic-level drivers without additional level shifting circuitry.
