TVS (Transient Voltage Suppressor) diodes, also known as Transient Voltage Suppressors, are a type of semiconductor device that is used to protect electrical circuits from brief reactive power surges. The 1.5KE150A R0G is one such device. This article discusses it application field and working principle.

Application Field

The 1.5KE150A R0G is an unipolar, low-voltage transient voltage suppressor diode. It is most commonly used for overvoltage suppression in consumer electrical devices such as TVs, computers, mobile phone chargers, professional video camera systems, and any other type of device that may be exposed to unpredictable power surges. It is also used in industrial power supplies, DC-DC converters, and automotive systems.

The 1.5KE150A R0G is a low capacity diode and is typically used in applications that require low-clamping capability and fast response time. It can clamp and dissipate up to 150 watts at 135V AC, 200 volts at 50 nanoseconds, and 1.0 amps steady-state. The device is also RoHS compliant and has high-temperature plastic SMD packages.

Working Principle

The 1.5KE150A R0G is a unipolar device, meaning that it has only one junction or PN junction. It works by absorbing any transient voltage or excess electric energy present in a circuit, preventing it from reaching other components in that circuit. When a voltage surge occurs, the device acts as a clamp to absorb any excess energy, dissipating it as heat instead of allowing it to cause damage to the other components in the circuit.

The 1.5KE150A R0G is optimized for low-clamping capability and fast response times. It is constructed from a diffusion-doped silicon chip and is designed to suppress voltage surges from both common-mode and differential-mode sources. Its low capacitance value helps to reduce both switching losses and ringing interference.

The 1.5KE150A R0G is a unipolar, low-voltage transient voltage suppressor diode with a wide range of applications. It works by clamping and absorbing transient voltage or excess electric energy in a circuit, protecting other components from the damaging effects of surges in power. It is optimized for both low-clamping capability and fast response time, making it an ideal choice for overvoltage suppression in consumer electronics and other situations where brief reactive power surges may occur.
