‡ Maximum power dissipation is calculated assuming that the device is mounted on FR4
substrate measuring 40x40x0.6mm and using comparable measurement methods adopted by
other suppliers.
**Measured under pulsed conditions. Pulse width=300µs. Duty cycle ≤ 2%
Spice parameter data is available upon request for these devices
