The HGT1S20N60A4S9A is a MOS-gated high voltage N-channel IGBT designed for switch mode power supplies. It combines the high input impedance of a MOSFET with the low on-state conduction loss of a bipolar transistor. The device features a collector-emitter breakdown voltage (BVCES) of 600 V and supports continuous collector currents up to 70 A at 25°C case temperature. It operates within a junction temperature range of -55°C to 150°C, with a total power dissipation of 290 W at 25°C. The component utilizes a TO-263AB package.
Verify the complete part number including the S9A suffix during ordering. Confirm that the component is sourced from Fairchild Semiconductor or authorized distributors, as indicated by the datasheet copyright. Ensure handling precautions are followed due to electrostatic discharge susceptibility.
Select this component when designing circuits requiring 600V blocking capability and high current handling up to 70A. Consider the thermal resistance of 0.43°C/W and the need for adequate heat sinking to maintain junction temperatures below 150°C under load conditions.
This device belongs to the SMPS Series N-Channel IGBTs line. It was formerly identified as Developmental Type TA49339. The product is covered by multiple United States patents held by Fairchild Semiconductor Corporation.
