Notes:
Repetitive rating; pulse width limited by
max. junction temperature.
Starting TJ = 25°C, L = 0.85mH
RG = 25Ω, IAS = 30A.
Pulse width ≤ 400µs; duty cycle ≤ 2%.
This is only applied to TO-220AB package
This is applied to D2Pak, when mounted on 1" square PCB ( FR-4 or G-10 Material ).
For recommended footprint and soldering techniques refer to application note #AN-994.
Calculated continuous current based on maximum allowable
junction temperature. Package limitation current is 75A.
Data and specifications subject to change without notice.
This product has been designed and qualified for the industrial market.
Qualification Standards can be found on IR’s Web site.
