Absolute Maximum Ratings
(Ta=25
°
C, unless otherwise specified)
Note:
1. Repetitive rating: Pulse width is limited by maximum junction temperature
2. L = 24mH, starting Tj = 25

Thermal Impedance
(Ta=25
°
C, unless otherwise specified)
Note:
1. Free standing with no heatsink; Without copper clad.
/ Measurement Condition : Just before junction temperature T
J
enters into OTP.
2. Measured on the DRAIN pin close to plastic interface.
- all items are tested with the standards JESD 51-2 and 51-10 (DIP).
