SMCJ15E3/TR13

Transient Voltage Suppressor (TVS) Diodes are widely used to provide protection against transients and other electrical disturbances in electronic circuits. The SMCJ15E3/TR13 is a Uni-Directional Transient Voltage Suppressor Diode which is designed specifically to protect sensitive electronic components from over-voltage transients. It suppresses transients of both polarities, providing protection up to 15 volts and 1500 Watts.

Application

The SMCJ15E3/TR13 Transient Voltage Suppressor Diode is rated for power handling up to 1500 Watts, with an operating voltage range of 15 to 20 Volts. It is commonly used in a variety of applications, from industrial electronics to automotive components.

In automotive applications, the SMCJ15E3/TR13 finds use in automotive body controls, vehicle security systems, and power train electronics. It is also widely used in industrial control systems and power supplies, as it provides efficient protection against over-voltage transients, while having low clamping voltage and current ratings. It is also an ideal choice for consumer electronics where circuit board protection is essential.

Working Principle

The SMCJ15E3/TR13 Transient Voltage Suppressor Diode works by clamping the voltage across the diode to a predetermined value. It does this by limiting the amount of current that can flow through the diode when the voltage is exceeding the diode\'s breakdown voltage. The voltage at which the diode starts to conduct current is known as the breakdown voltage or clamp voltage.

When the transient voltage exceeds the breakdown voltage, the diode begins to conduct current, which causes a slight voltage drop across the diode. This voltage drop limits the amount of voltage that can be applied to the load, thereby limiting the possible damage caused by an over-voltage transient. The diode is designed to be able to withstand very high current levels, allowing it to protect sensitive electronics in the face of high-amplitude voltage spikes.

In applications where the frequency of the transient voltage is high, the diode will be forced to turn off more quickly and enter a region where it is unable to effectively suppress transient voltages. In these cases, multiple diode stages may be used to provide more effective protection.

Conclusion

The SMCJ15E3/TR13 is a Uni-Directional Transient Voltage Suppressor Diode which is designed to provide an efficient and reliable means of protecting sensitive electronics against over-voltage transients. It provides a voltage clamping level of 15 Volts and an operational power rating of 1500 Watts. The diode works by limiting the amount of current that can flow through the diode when the voltage is exceeding the diode\'s breakdown voltage. The diode is widely used in a variety of automotive and industrial applications, providing reliable protection against transient voltage spikes.
