The SA03 is constructed from MOSFET transistors. ESD handling procedures must be observed.

The internal substrate contains beryllia (BeO). Do not break the seal. If accidentally broken, do not crush,

machine, or subject to temperatures in excess of 850°C to avoid generating toxic fumes.

CAUTION

NOTES: 1.

Each of the two active output transistors can dissipate 150W.

2.

Unless otherwise noted: T

3.

Long term operation at the maximum junction temperature will result in reduced product life. Derate internal power

dissipation to achieve high MTTF. For guidance, refer to the heatsink data sheet.

4.

Guaranteed but not tested.

5.

If 100% duty cycle is not required V
