A transient suppressor for an electronic circuit includes a hermetically sealed housing for a Zener diode having a thin thermally conductive cover in thermal engagement with the Zener diode near the junction thereof and a heat dissipating member extending from the diode through the bottom of the package. A thermal circuit breaker seated in the depressed portion of the dish-shaped cover has a temperature responsive element normally in intimate engagement with the cover to sense the diode junction temperature. A base member supporting the diode housing and the circuit breaker carries a leaf spring for biasing the circuit breaker against the diode housing. The spring is removable to allow easy replacement of the diode or the circuit breaker when defective. External circuit connections which may include a fuse, places the circuit breaker in series with the Zener diode to prevent current flow through the diode when the junction temperature reaches a critical point.
