SWITCHING PARAMETERS

A: The value of RθJA is measured with the device mounted on 1in

2 FR-4 board with 2oz. Copper, in a still air environment with T

A =25°C. The

Power dissipation PDSM is based on R θJA and the maximum allowed junction temperature of 150°C. The value in any given application depends

on the user's specific board design, and the maximum temperature of 175°C may be used if the PCB allow s it.

B. The power dissipation PD is based on TJ(MAX)=175°C, using junction-to-case thermal resistance, and is more useful in setting the upper

dissipation limit for cases where additional heatsinking is used.

C: Repetitive rating, pulse width limited by junction temperature TJ(MAX)=175°C. Ratings are based on low frequency and duty cycles to keep

initial TJ =25°C.

D. The RθJA is the sum of the thermal impedence from junction to case RθJC and case to ambient.

E. The static characteristics in Figures 1 to 6 are obtained using <300

µs pulses, duty cycle 0.5% max.

F. These curves are based on the junction-to-case thermal impedence which is measured with the device mounted to a large heatsink, assuming

a maximum junction temperature of TJ(MAX)=175°C. The SOA curve provides a single pulse ratin g.

G. The maximum current rating is limited by bond-wires.

H. These tests are performed with the device mounted on 1 in

2 FR-4 board with 2oz. Copper, in a still air environment with T

A=25°C.
