## **TO-220AC** 

## RoHS Compliant 

- Low QRR, low IRRM, low tRR 

- High dIF/dt capable (1000 A / µ s) 

- Soft recovery 

## **Benefits** 

- Increases efficiency 

- Eliminates need for snubber circuits 

- Reduces EMI filter component size & count 

- Enables extremely fast switching 

Package uses Lead-free plating and Green mold compound. 

Halogen free per IEC 61249-2-21. 

## **Absolute Maximum Ratings** 

Absolute maximum ratings are the values beyond which the device may be damaged or have its useful life impaired. Functional operation under these conditions is not implied.
