TVS – Diodes are widely used in a variety of applications. In this article, we will discuss the application field and working principle of a 1.5CE120A TR, a low-profile, bi-directional, ultra-fast Transient Voltage Suppressor (TVS) – Diode. The device is specifically designed to protect sensitive electrical and electronic equipment from damage caused by voltage transients.

1.5CE120A TR is a high-performance TVS – Diode capable of protecting sensitive components from spikes and short-term overvoltage transients. It offers a robust surge-current rating of up to 40A, a very fast response time of less than 1 nanosecond, and a reverse leakage current of only 0.01 μA as well as a low capacitance of only 30pF. The device is suitable for use in a wide range of applications including automotive, consumer, industrial, and medical applications. All of these performance characteristics make the device ideal for use in applications where high-speed transients and snaps are encountered.

The most common application for 1.5CE120A TR is in the protection of sensitive electronic components from overvoltage transients caused by lightning, switching transients, and voltage spikes. For example, it can be used in automotive applications to protect sensitive electronics from voltage transients related to the vehicle starting and stopping or power cycling. Additionally, the device can be used to protect communication equipment, such as telecommunication systems, from voltage transients related to heavy line current induced by lightning. The device is also suitable for protecting sensitive computer components from induced transients and other asymmetrical voltage transients.

The 1.5CE120A TR is also capable of providing some degree of ESD (Electrostatic Discharge) protection. It offers an ESD performance of ± 15 kV, making it suitable for use in most applications requiring ESD protection. Additionally, the device provides excellent ESD temperature stability over a range of temperature changes, making it ideal for use in applications requiring temperature range variations.

The working principle of 1.5CE120A TR is very simple. When a surge or transient voltage appears on any of its two input terminals, it conducts the excess current resulting in a rapid reduction of the voltage across the protection element. The device then absorbs the current, allowing the voltage on the protected side to return to its normal specification. The device also provides some level of protection against a reverse voltage polarity, by quickly conducting the reverse current, thereby removing the excess voltage.

In conclusion, 1.5CE120A TR is a high-performance TVS – Diode that is ideal for use in applications requiring fast response times, low leakage currents, robust surge-current ratings, and excellent temperature stability. The device is capable of providing superior protection for sensitive electronic components against voltage transients due to lightning, switching transients, and voltage spikes, as well as providing ESD protection. The device’s simple working principle allows for fast transient protection, thereby ensuring that electronic components remain safe and reliably operational.
