| MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MR2835S/D Designer'sTM Data Sheet Overvoltage Transient Suppressor . . . designed for applications requiring a diode with reverse avalanche characteristics 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.
