Transient Voltage Suppression (TVS) diodes provide a simple solution for protecting circuits from over-voltage transients. The SMAJ13CHE3/5A is a TVS diode designed to protect circuits against electrostatic discharge (ESD) and voltage transients. This diode has a low capacitance and good high-speed response time.

Application Field:

The SMAJ13CHE3/5A TVS diode is suitable for many applications including automotive ESD protection, industrial ESD protection, power supply protection, data line protection, and consumer electronics protection. This diode is often used in devices such as automotive computers, communication modules, LCD displays, LCD monitors, and cellular phones.

Working Principle:

The SMAJ13CHE3/5A TVS diode is composed of a pair of PN diode structures. When the diode is forward-biased, electrons from the PN junction flow to the N-type side, creating a voltage drop and allowing current to flow freely. When a transient voltage is applied to either the anode or the cathode of the diode, the voltage across the PN junction increases and enters a state of avalanche breakdown, allowing the current to be diverted away from the forward biased direction and toward the source of the transient voltage. This process provides protection against over-voltage transients.

The SMAJ13CHE3/5A is designed to be fast enough to handle the high-speed signals commonly used in digital applications. It also has low capacitance, allowing it to work with higher frequencies without becoming over-stressed.

Conclusion:

The SMAJ13CHE3/5A is a TVS diode designed for ESD and voltage transient protection. Its low capacitance and fast response time make it suitable for a wide range of applications including automotive, industrial, and consumer electronics. Its PN junction structure also allows for fast response to transient over-voltages, providing superior protection against ESD and other transients.
