Continuous Drain Current @TC=25°C, VGS=10V
Continuous Drain Current @TC=100°C, VGS=10V
Continuous Drain Current @TA=25°C, VGS=10V
Continuous Drain Current @TA=70°C, VGS=10V
Pulsed Drain Current @ VGS=10V
Single Pulse Avalanche Energy @ L=10mH, ID=5A, VDD=50V
Operating Junction and Storage Temperature
Thermal Resistance, Junction-to-case, max
Thermal Resistance, Junction-to-ambient, max (Note 2)
Note : 1.The power dissipation PD is based on TJ(MAX)=150°C, using junction-to-case thermal resistance, and is more useful
in setting the upper dissipation limit for cases where additional heatsinking is used.
2.The value of RθJA is measured with the device mounted on 1 in²FR-4 board with 2 oz. copper, in a still air
environment with TA=25°C. The power dissipation PDSM is based on RθJA and the maximum allowed junction
temperature of 150°C.
3. Pulse width limited by junction temperature TJ(MAX)=150°C. Ratings are based on low frequency and low duty cycles
to keep initial TJ=25°C.
4. 100% tested by conditions of L=100μH, IAS=5A, VGS=10V, VDD=50V
