Zd10-100 Datasheet -

Internal sensor trips at ~85°C case temperature. The power supply shuts down and automatically restarts when cooled to 65°C.

The ZD10-100 is a with a nominal Zener voltage of 10V . It belongs to a family of small-signal Zener diodes designed for voltage regulation, clipping, and reference applications in low-power circuits. zd10-100 datasheet

Used in conjunction with an SCR to protect low-voltage logic. If the input supply exceeds 10.6V, the Zener conducts, triggering the SCR and shorting the supply. Internal sensor trips at ~85°C case temperature
