Custom High Voltage Suppressors

What are Hazardous Transient Threats?

A Hazardous Transient Threat is any unexpected or unanticipated change in voltage caused by an unpredictable and sometimes unprecedented occurrence. Very often it is a random electrical phenomenon, such as a high voltage or current pulse for a brief duration of time.

Electrostatic threats are categorized into four basic groups:

1. NUCLEAR ELECTROMAGNETIC PULSE(NEMP)Transient
2. LIGHTNING STRIKE
3. INDUCTIVE SWITCHING (EMI)
4. ELECTROSTATIC DISCHARGE (ESD)

High Voltage Suppressors are designed to protect sensitive Electronic equipment during hazardous transient conditions. They are employed to absorb a potentially destructive overshoot voltage. Under normal voltage conditions, the suppressor circuit exhibits high off-state impedance and appear transparent to the circuits they protect. If a voltage exceeding the switching voltage is applied to the circuit, the suppressor circuit switches to very low impedance effectively shorting out the high voltage. The suppressor circuit will remain in the low impedance state until the current flowing through the suppressor is either interrupted or drops to a safe level. Once this occurs, the suppressor resets and returns to a high off-state impedance.
