Thermal Data
N-Channel Electrical Characteristics (TJ=25 ℃, unless otherwise noted)
Guaranteed Avalanche Characteristics
Note :
1. The data tested by surface mounted on a 1 inch2 FR-4 board with 2OZ copper.
2. The data tested by pulsed , pulse width ≦ 300us , duty cycle ≦ 2%
3. The power dissipation is limited by 150℃ junction temperature
4. The data is theoretically the same as ID and IDM , in real applications , should be limited by total power dissipation.
