TVS (Transient Voltage Suppressor) diodes are widely used in electronics applications in order to protect them from overvoltage transients. A popular choice for protection is the SMCJ1.5KE400A-TP TVS Diode. This device is typically used to protect against overvoltage transients such as those generated due to load dump, induction, and lightning. The SMCJ1.5KE400A-TP is a unidirectional-bidirectional diode with an operating voltage of 400V, reverse breakdown of 5V and a clamping voltage of 15V.

The SMCJ1.5KE400A-TP is applicable in the automotive and industrial applications. Its typical applications include surge protection in engine control systems, relay coils, input/output control systems, actuators/valves, automotive ECUs, and hybrids. The device is also suitable for DC/DC converters, voltage regulators, shut down and power supply circuits, cell phone circuits, opto-electronic components, non-linear circuits, and PLCs.

The SMCJ1.5KE400A-TP is a low capacitance device, which helps to reduce the effect of input surge on the output signal by discharging high frequency pulses. This protects the line from DC level injection and reduces signal loss in data lines. The device features fast response time with excellent clamping capability and is designed to meet the IEC61000-4-2 (ESD) and IEC61000-4-5 (surge) standards.

The working principle of the device is fairly simple. When a transient voltage exceeds the breakdown voltage level of the device, electrons flow from the cathode to the anode. This process helps to limit the voltage on the device to the breakdown level. The reverse breakdown voltage of the device is very low and it helps to protect the device from high voltage pulses.

The SMCJ1.5KE400A-TP offers excellent performance in transient overvoltage pulse handling and it is well suited for protecting sensitive electronics from transients. The high clamping voltage of the device makes it an ideal choice for surge protection in industrial, automotive, and other applications. Due to its fast response time, the device can protect against voltage transients with high speed.
