TVS - Diodes

Transient Voltage Suppression (TVS) diodes are specialized semiconductor devices that protect sensitive electronics from damaging voltage transients caused by electrical fields. The SM16LC05C/TR13 from Taiwan Semiconductor is a popular choice for many applications as it features a low stand-off voltage, fast return times, low capacitance and low leakage current, combined with a small footprint. In this article, we’ll take a look at the application fields and working principle of this component.

Application Fields

Due to its strong transient protection capabilities, the SM16LC05C/TR13 can be used in many applications in areas such as automotive, industrial, medical and military. Its low breakdown voltage of 9.3 V and small footprint of 1.6mm × 1.6mm makes it a great choice for applications in compact devices.

It is especially popular in automotive applications due to its fast response time of 10 nanoseconds. This includes applications such as ESD protection, smart key remote entry systems, TPMS, DCDC converters, audio systems and power windows.

In industrial applications, the SM16LC05C/TR13 can be used in devices such as Programmable Logic Controllers (PLCs), industrial PCs, automation and process control. In medical applications, it is used in blood pressure monitors, patient monitors and other medical equipment.

Working Principle

The SM16LC05C/TR13 is a bidirectional TVS diode, meaning that it can protect against both positive and negative voltage transients. It is constructed from a diode and resistor connected in parallel. When a voltage transient occurs, the diode is suddenly switched on, decreasing the voltage across the resistor. This decreases the current flow and dissipates any excess energy that would otherwise damage the circuit.

The diode is designed to operate from a +4.5V to +32V and has a maximum clamping voltage of 13.5V. It can handle peak surge up to 400W and is rated at 1A. It also has a fast response time of 10 nanoseconds, making it suitable for use in high-speed applications such as automotive electronics.

Conclusion

The SM16LC05C/TR13 from Taiwan Semiconductor is an excellent choice for protecting sensitive electronics from transient voltage events. It is suitable for use in a variety of applications ranging from automotive and industrial to medical and military. With its low stand-off voltage, fast response time, low capacitance and low leakage current, this TVS diode is a great choice for many applications.
