The industry's first surface-mounted 240 V/1 kA bidirectional power TVS diode

     Bourns, the world's leading manufacturer of electronic components for power, protection and sensing solutions, has again demonstrated its leadership in innovation and technology with the introduction of the industry's first 240 V/1 kA bidirectional power TVS (PTVS) diode, which offers the highest power density in a surface-mount package. The Bourns PTVS1-240C-M PTVS diode uses advanced silicon process technology, has extremely high voltage handling capacity, and the diode's surface mount package makes this transient voltage protector stand out.

     The Bourns PTVS1-240C-M offers 1 kA of surge handling at 8/20 µs, making it ideal for a wide range of systems with a high voltage DC bus architecture. These systems typically experience high-current switching transients and dynamic load behavior, requiring the use of absorbing circuits or protection of bus-powered subsystems. The introduction of Bourns® PTVS diodes provides a reliable solution for high-voltage applications that require robust protection.

     The Bourns PTVS1-240C-M PTVS diode is a low leakage current device that consumes only 10 µA of current in standby mode and has a maximum breakdown voltage of 295 V, a repeated reverse operating voltage of 240 V and a precise clamp voltage of 340 V. Even at 10/350 µs, the device has A rated peak current of 200 A, and its voltage breakdown sensitivity to temperature is extremely linear, only 0.1% /°C. The diode's surface-mount package significantly reduces the PCB's board area and has the advantage of a lower inductance design compared to conventional through-hole mounted power TVS diodes.

     The Bourns PTVS1-240C-M features and functions for a wide range of applications, including industrial power systems, motor controllers and inverters, solar inverters, battery energy storage systems, and factory automation. These applications take advantage of the device's high performance and reliability to provide superior overvoltage protection for the system.
