Technical Parameters Of Surge Protector Suppression Diode Components
(1) Breakdown voltage: This refers to the breakdown voltage of the surge protective device at a specified reverse breakdown current (usually LMA). The rated breakdown voltage of a Zener diode is generally in the range of 2.9V to 4.7V, while the rated breakdown voltage of an avalanche diode is usually in the range of 5.6V to 200V.
(2) Maximum clamping voltage: This refers to the maximum voltage that appears at both ends of the tube when a large current with a specified waveform passes through it.
(3) Pulse power: This refers to the product of the maximum clamping voltage at both ends of the tube and the current in the tube under a specified current waveform (such as 10/1000μs).
(4) Reverse displacement voltage: This refers to the maximum voltage that can be applied to both ends of the tube in the reverse leakage region, at which the tube should not break down. This reverse displacement voltage should be significantly higher than the peak value of the highest operating voltage of the protected electronic system, that is, it cannot be in a weak conduction state during normal operation of the system.
(5) Maximum leakage current: This refers to the maximum reverse current flowing through the surge protector tube under the action of the reverse displacement voltage.
(6) Response time of surge protection device suppression diode element: 10-11s
