2SK3199

Overview

The Sanken Electric USA Inc. 2SK3199 is a single-element N-channel silicon MOSFET designed for power switching applications. It features a drain-source breakdown voltage of 500 V and a continuous drain current rating of ±5 A at a case temperature of 25°C. The device supports a pulsed drain current of ±20 A and dissipates up to 30 W with an infinite heatsink. Key electrical characteristics include a maximum gate-source voltage of ±30 V, a typical on-resistance (RDS(on)) of 1.2 Ω at VGS = 10V and ID = 2.5A, and a threshold voltage ranging from 2.0 V to 4.0 V. The component is housed in the FM20 (TO-220F) or FM100 (TO-3PF) package.

Feature Summary

• High-voltage capability with a 500 V drain-source breakdown voltage suitable for demanding power conversion circuits.
• Robust avalanche energy handling rated at 35 mJ under specified unclamped inductive load conditions.
• Low thermal resistance design enabling efficient heat dissipation for continuous operation up to 30 W.

Applications

• Power supply circuits requiring high-voltage isolation and switching
• Motor driver interfaces for controlling inductive loads
• General-purpose power switching modules

Procurement Notes

Verify the specific package variant required for your design, as the datasheet lists both FM20 (TO-220F) and FM100 (TO-3PF) external dimensions. Confirm that the ordering suffix matches the desired mounting style and lead configuration. Ensure the supplier provides documentation confirming the UL approval status if safety certification is mandatory for your application. Cross-reference the lot number markings against the manufacturer's latest revision history to guarantee component authenticity and traceability.

Selection Notes

Select this component when designing circuits that require a 500 V blocking voltage combined with moderate current handling capabilities around 5 A. The relatively high RDS(on) of 1.2 Ω suggests it is best suited for lower-current applications or where conduction losses are secondary to switching speed and voltage tolerance. Consider the thermal management requirements carefully, as the 30 W power dissipation rating depends heavily on the heatsinking method and ambient temperature conditions during operation.
