PRODUCT INFORMATION
NOTES: 3. These parameters must be measured using pulse techniques, tp = 300 µs, duty cycle ≤ 2%.
4. These parameters must be measured using voltage-sensing contacts, separate from the current carrying contacts.
† Voltage and current values shown are nominal; exact values vary slightly with transistor parameters.

PRODUCT INFORMATION
TO-220
3-pin plastic flange-mount package
This single-in-line package consists of a circuit mounted on a lead frame and encapsulated within a plastic
compound. The compound will withstand soldering temperature with no deformation, and circuit performance
characteristics will remain stable when operated in high humidity conditions. Leads require no additional
cleaning or processing when used in soldered assembly.
