Operation of a Trisil crowbar type protection diode

Introduction
In the field of parallel protection, the devices used have two main functions in transient
operation.
■ Limit the voltage.
■ Divert the surge current.
If the first function is carried out perfectly by an avalanche junction, confirmed by the
success of the Transil series, the second is limited by voltage permanently present across
the diode terminals.
Use of increasingly sophisticated but fragile el
