Application note
Transil™
clamping protection mode
Introduction
The Transil^(a) is an avalanche diode specially designed to clamp over voltages and dissipate
high transient power. A Transil has to be selected in two steps:
• Check that the circuit operating conditions do not exceed the specified limit of the
component.
– For non-repetitive surge operation,
– For repetitive surge operation,
– For normal operation.
• Check that the maximum value of the clamped voltage under the worst conditions
corresponds to the specification of the circuit.
