integral transient suppression diodes. Use of a predriver stage reduces input
current while still allowing the device to switch 1.5 Amps.
contact tabs (Pins 4, 5, 12 and 13). A copper alloy lead frame allows maximum
power dissipation using standard cooling techniques. The use of the contact
tab lead frame facilitates attachment of a DIP heat sink while permitting the
use of standard layout and mounting practices.
