The 1N6288A is an onsemi Mosorb™ Zener transient voltage suppressor (TVS) diode in a DO-201AD axial leaded package, rated for 1500W peak pulse power at 10/1000 µs waveform. It is designed for general-purpose circuit protection where a single unidirectional channel must clamp transients above 43.6V reverse standoff. The device has a minimum breakdown voltage of 48.5V and a maximum clamping voltage of 70.1V at its rated peak pulse current. This means the protected rail sees no more than 70.1V during a surge event, which is the key number for design margin. It operates over a junction temperature range of -65°C to 175°C, making it suitable for harsh environments such as industrial power supplies, telecom line cards, and military-grade equipment where wide thermal tolerance is required.
For existing BOM lines, procurement must source from independent distributors or the open market. The part is available in an axial package, which is through-hole and bulk-packaged. The base product number is 1N6288.
