A1225UC4LTP

TVS (Transient Voltage Suppressor) thyristors are semiconductors that are used to protect electronic equipment from damage caused by voltage spikes or transients. The A1225UC4LTP series thyristor is specifically designed for Transient Voltage Suppression (TVS) applications and provides superior protection against voltage spikes. This device offers a combination of low power consumption, fast response time, and high current handling capability.

A1225UC4LTP application field includes:

• Automotive electronics
• Industrial and medical equipment
• Telecommunication systems
• Computer and data processing systems
• Consumer electronics

The A1225UC4LTP is a fully integrated, PNPN, surface mount TVS. It has an operating voltage range of 4.5V to 70V and a peak pulse current rating of 11.7A. It is designed to protect against transient voltages up to 600V. The device has a low capacitance of 0.18pF, which makes it suitable for low-power applications. The device also has a low power consumption of 4μA and a fast response time of 0.25µs.

The A1225UC4LTP thyristor works by clamping the transient voltage to the clamping voltage, which is dependent on the device’s reverse breakdown voltage (BV). When the transient voltage exceeds the clamping voltage, the device conducts the transient current, dissipating the excess energy and reducing the voltage to a safe level. The device automatically turns off once the transient voltage falls below the clamping voltage.

The A1225UC4LTP is used in applications where power and performance are of paramount importance. It offers superior protection against voltage spikes and transients, fast response time, and very low power consumption. The device is also able to dissipate large amount of transient energy, thereby providing a reliable protection for the protected circuit.
