What this Zener does on your board
It is designed for general-purpose transient suppression — think industrial control panels, telecom line cards, or power supply rails that see repetitive surge events. The 75V reverse standoff means it sits across a 48V or 60V bus and stays out of the way until a spike pushes past 86.5V breakdown.
Temperature range and field reliability
Rated for -55°C to 175°C junction temperature, this part handles the thermal swing of outdoor cabinets, engine bays, or avionics bays without derating drama. The DO-13 through-hole package is a metal can with a glass seal — it survives vibration and humidity better than a plastic SMD part, and you can swap it on site with a soldering iron and a pair of pliers. No hot-air station needed.

Package and mounting fit
DO-13 (also known as TO-5 with a stud) is a through-hole package with two axial leads. The 0.200-inch lead spacing fits standard 0.100-inch grid prototyping boards. The metal case is the cathode — orientation matters, but the band on the body and the datasheet marking make it unambiguous. No special footprint beyond the two holes and a bit of copper for thermal relief.
