TVS (Transient Voltage Suppressor) diodes, also known as transorbs, are a specialized type of semiconductor diode designed to protect sensitive electronics and integrated circuits from transient voltage overshoots or surges. The SAC12-TP is an ultra-fast, high-energy transient voltage suppressor (TVS) diode designed to protect telephone equipment from transient overvoltages resulting from electrostatic discharge (ESD) attacks. In this article, we will discuss the application field and working principle of the SAC12-TP.

Application Field

The SAC12-TP is designed for telephone equipment needing protection against ESD. The diode can withstand ESD pulses up to 15KV HBM on the machine model (contact). The SAC12-TP can handle up to 5KV HBM on the human body model (air).

It is well known that telephone equipment is exposed to a wide range of transient overvoltage, from lightning strikes to ESD. The SAC12-TP is designed to protect these sensitive pieces of equipment from voltage overshoots. Additionally, the SAC12-TP has a low static operating voltage of 5.5V, and can protect up to 1.5A at a temperature range of -55C to +125C. This makes the SAC12-TP ideal for applications that demand reliable protection and performance.

Working Principle

The operation of the SAC12-TP is based on a negative-temperature-coefficient principle (NTC). When the diode is subjected to a surge, it acts like a short circuit, providing a low resistance shunt path, and clamping the transient voltage to a level below the device\'s breakdown voltage. This is done by dissipating the energy of the surge current through the heatsink mounted on the diode.

The main advantge of the SAC12-TP is its ultra-fast response time. When subjected to a fast rising transient overvoltage, the device responds in less than 90 nanoseconds, minimizing the risk of equipment damage. Additionally, its low dynamic impedance minimizes ringing, making it an ideal choice in high-frequency applications.

Conclusion

The SAC12-TP is an ultra-fast high-energy transient voltage suppressor (TVS) diode designed to protect telephone equipment from transient overvoltages resulting from electrostatic discharge (ESD) attacks. It offers an excellent protection against a wide range of transient voltages, and its fast response time and low impedance ensure reliable signal integrity. Additionally, the SAC12-TP can withstand ESD pulses up to 15KV HBM on the machine model (contact) and up to 5KV HBM on the human body model (air). For these reasons, the SAC12-TP is an ideal choice for protecting sensitive electronics and integrated circuits from transient voltage overshoots and surges.
