Transient Voltage Suppressor (TVS) diodes have been around for some time and are used to protect electronic devices from overvoltage surge protection. TLPA17A is a silicon transient voltage suppressor (TVS) diode designed to protect against high-energy surges caused by direct or indirect electrostatic discharges or surges encountered in automotive, industrial and consumer applications.

TLPA17A provides excellent transient overvoltages protection and is specifically developed for applications that require high reliability and long life reliability. It is specified for high-energy pulse events up to 30kV (2/10µs), and can trigger on any type of transient surge.

TLPA17A features Breakdown Voltage options from 11.5V - 15V, ESD Clamping Voltage (min) 8V, and Clamping Voltage (max) 30V. It is mounted in a SOD-323FL package and it is a low forward voltage drop diode, featuring low thermal resistance as well as low reverse leakage. The device is UL 94V-0 compliant and fabricated using polysilicon gate technology.

TLPA17A can withstand voltages that exceed the breakdown voltage and can be used in both reverse and forward biased applications. The device is designed to be highly reliable and has an extremely fast response time. This makes it suitable for high-energy pulse applications where overvoltage protection is required.

The working principle of TLPA17A is that when a transient voltage is applied to the device, it inhibits the flow of electrical current until the applied voltage passes through the breakdown voltage. Then the device acts as a low-impedance conducting path, providing the protection of the valuable electrical components connected to it.

TLPA17A can be used in a variety of automotive, industrial and consumer applications requiring high energy pulse protection. Such applications include automotive charger ports, entertainment systems and portable electronic equipment, including mobile phones, laptops and tablet PCs. The device can also be used in various industrial environments where sensitive electronic components are subjected to transient overvoltages.

The device provides reliable overvoltage protection and is designed to operate in both forward and reverse biased applications, and has proven to be a reliable solution for automotive, industrial and consumer applications. Its low forward voltage drop enables energy efficient operation of the device, and its low thermal resistance ensures improved design flexibility.
