1.5KE130ATR

The 1.5KE130ATR is a power Transient Voltage Suppressor (TVS) diode. TVS diodes are designed to protect sensitive electro-mechanical components from transients generated by lightning, static discharge and power cross. 1.5KE130ATR is an active component designed to be placed in series with the protection device, also known as a shunting element. This component protects sensitive electro-mechanical components from both high- and low-voltage transients.

Application Fields and Working Principle

The 1.5KE130ATR TVS diode is specifically designed for use in the automotive industry. It is used to protect sensitive components within a vehicle\'s fuel, oil, and electronics system from transients generated by lightning, static discharge, and power cross. The 1.5KE130ATR is a unidirectional device, meaning it only protects the circuit from high-voltage transients, and not from low-voltage transients. It has excellent clamping capability, so it can handle a wide range of voltages and currents without damage.

The 1.5KE130ATR TVS diode works by shunting the transient voltage away from the protected circuit. When the voltage exceeds the device\'s breakdown voltage, it quickly responds and starts the transition from an off-state to on-state. As the voltage starts to exceed its breakdown voltage, a large current begins to flow through the diode. This causes a voltage drop across the diode, which reduces the voltage across the protected circuit and prevents any permanent or catastrophic damage. After the transient is gone, the diode returns to its off-state.

The 1.5KE130ATR is designed to be used in automotive and industrial applications. It has a very fast response time, which makes it ideal for protecting sensitive circuits from transients. Its low profile and small footprint makes it easy to install in tight spaces. Furthermore, it is hermetically sealed and has an operational temperature range of -55°C to +125°C, making it suitable for harsh environments.
