The SD12T1G with TVS Diodes - Transient Voltage Suppressors (ZENER TVS) from ON Semiconductor is an integrated circuit designed specifically for use as an alternate stress protection device from surges and spikes in electrical power.It operates using a pair of low-capacitance diodes, an integrated Zener diode, and a MOV (Metal Oxide Varistor). This combination provides protection from overcurrents, overvoltages, and ESD (electrostatic discharges). The MOV component is used to limit any high-energy, short-duration transients, while the Zener diode protects against more sustained high overvoltage events. Additionally, the low-capacitance diodes prevent the device from damage due to ESD. The SD12T1G with TVS is stable and robust, and is ideal for both automotive as well as industrial applications. It is able to “clamp” power and voltage surges, thus preserving the integrity of its device.
