1.5KE7.5CA

Transient Voltage Suppression (TVS) diodes are a type of semiconductor device used to protect electronic circuits from voltage surges induced by electrostatic discharge (ESD), lightning, environmental stress, and other transient conditions. They can also be used in high-frequency data and signal lines, motor drives, and radio and telecom applications. The 1.5KE7.5CA (or “1.5KE” TVS diode) is an unidirectional voltage suppressor with a stand-off voltage of 7.5 Volts, meaning it can protect circuits from transients up to 7.5V without clamping.

Application Field

The 1.5KE device is used in a variety of applications, including ESD protection, line termination, circuit isolation, and electrical noise suppression. It is particularly suited for situations where low leakage is required, and it can be used to protect both low-voltage, direct current (DC) and high-speed, alternating current (AC) transfer lines. It can also be used in high-frequency communications and data lines, such as Ethernet, USB, and T1. The 1.5KE is also used in automotive, industrial, and commercial applications, including motor drives, power supplies, and data converters.

Working Principle

The 1.5KE devices work using a Bidirectional Transient Voltage Suppressor (BTVS) technology which is based on the principle of charge balance. This technology uses two components, a bipolar NPN transistor and a Zener diode, which are connected in series to each other and to the power supply. When an overvoltage is applied to the transistor, the device is able to quickly draw the additional current away, thereby absorbing the transient. The 1.5KE device features a fast clamping response time (typically less than 4 nanoseconds) and a low capacitance rating.

Conclusion

The 1.5KE7.5CA TVS Diodes are a type of semiconductor device used to protect electronic circuits from a variety of transients. They are widely used in automotive, industrial, and commercial applications, and provide an effective solution for ESD protection, line termination, circuit isolation, and electrical noise suppression. The 1.5KE7.5CA devices feature a fast clamping response time and a low capacitance rating, making them an ideal choice for high-speed, alternating current transfer lines and high-frequency communications and data lines.
