Motorola Power Products Division Device Data
. . . designed for applications requiring a diode with reverse avalanche characteris-
tics for use as reverse power transient suppressor.
Developed to suppress transients in the automotive system, this device operates
in reverse mode as power zener diode and will protect expensive modules such as
ignition, injection and autoblocking systems from overvoltage conditions.
