Notes:
Repetitive rating; pulse width limited by max. junction temperature.
Starting TJ = 25°C, L = 0.43mH, RG = 25Ω, IAS = 20A.
Pulse width ≤ 400µs; duty cycle ≤ 2%.
Calculated continuous current based on maximum allowable junction temperature.
Package limitation current is 50A.
When mounted on 1" square PCB (FR-4 or G-10 Material). For recommended footprint and soldering techniques
refer to application note #AN-994.
Rθ is measured at TJ approximately 90°C.
Data and specifications subject to change without notice.
