What is a transient suppression diode?
Transient Voltage Suppressor (Transient Voltage Suppressor) is abbreviated as TVS, which is a high-efficiency protection device in the form of a diode. When the two poles of the TVS diode are impacted by the reverse transient high energy, it can change the high impedance between the two poles to low impedance at a speed of 10 to the negative 12th power, and absorb up to several kilowatts of surge power , The voltage clamp between the two poles is located at a predetermined value, which effectively protects the precision components in the electronic circuit from the damage of various surge pulses.

Because it has the advantages of fast response time, large transient power, low leakage current, breakdown voltage deviation, easy control of clamping voltage, no damage limit, and small size.

Widely used in computer systems, communication equipment, AC/DC power supplies, automobiles, electronic ballasts, household appliances, instruments and meters

(Watt-hour meter), RS232/422/423/485, I/O, LAN, ISDN, ADSL, USB, MP3, PDAS, GPS, CDMA, GSM, digital camera protection, common mode/differential mode protection, RF coupling /IC driver receiving protection, motor electromagnetic interference suppression, audio/video input, sensor/transmission, industrial control circuit, relay, contactor noise suppression and other fields.

model

The main models of transient suppression diodes are: XESD12VT23-3, an independent brand of IC network supermarkets. Very cost-effective.
XESD12VT23-3 is a two-way array of transient voltage suppression, designed to protect components, connected to data and transmission lines, against electrostatic discharge (abbreviated as ESD), electrical fast transient (EFT), and lightning. All pins are divided into a method that can withstand 20kv and use IEC 61000-4-2 anti-static pulse contact discharge method.
