SEMITEC Voltage Regulating Diode (VRD)
is a transient voltage suppressor device
that is designed to absorb voltage
surges and spikes that occur during
power initiation. Our VRD features
uniform avalanche breakdown across the
junction, enabling very fast response to
surge voltage.
Furthermore its control voltage is
almost independent from the current
which makes it a highly reliable, high
performance device.
Applications
- Protection of telecommunications line and
equipment from lightning-induced surges
- ESD protection
- EMP protection
- Relays, solenoids, etc., switching surge
protection
- Surge protection of fire alarms, smoke
detectors, etc.
- Protection of electric circuits from
abnormal voltage conditions
