Repetitive rating; pulse width limited by

max. junction temperature.

Starting TJ = 25°C, L = 20mH, RG = 25Ω,

IAS = 12A.

Pulse width ≤ 400µs; duty cycle ≤ 2%.

Notes:

Calculated continuous current based on maximum allowable

junction temperature. Package limitation current is 30A.

When mounted on 1" square PCB (FR-4 or G-10 Material).

For recommended footprint and soldering techniques refer to

application note #AN-994.
