JANTXV1N973CUR-1

Introduction

JANTXV1N973CUR-1 belongs to a category of diodes called Zener diodes, which are specialized because of their voltage regulating characteristics. This is a single Zener diode, which means – unlike a dual Zener diode – that it has only one junction. This particular diode supports up to 5W of power and has far less voltage regulating capabilities than dual Zener diodes, with a range of 3.3 to 52V. It is designed for the consumer electronics and telecom markets, and it often comes with a maximum recovery time of 6ns.

Application Field

JANTXV1N973CUR-1 is typically used in consumer electronics, telecom, and computers. Its key characteristic, its outstanding voltage- and current- regulating capabilities, makes it an ideal choice for applications that need to protect delicate circuits from high and low power supplies, voltage drops, and sudden power shut off. It is most frequently used in the TV and PC monitor industries, as well as in portable devices, satellite equipment, and telecom products.

Working Principle

JANTXV1N973CUR-1 operates by virtue of the Zener effect. Normally when a low-voltage electric current passes through a reverse biased diode, no current flows. But when the voltage is higher than the Zener voltage, a current begins to pass through the semiconductor junction. This allows the diode to regulate the current and provide protection against over-voltage, under-voltage, and sudden power shut off.

The JANTXV1N973CUR-1 also features a surge limitation, to provide extra protection against voltage and current fluctuations. This is due to its high-power, lightning-fast recovery time. Under normal operating conditions, this diode can handle up to 5W of power and has a maximum recovery time of 6ns.

Conclusion

JANTXV1N973CUR-1 is a single Zener diode with capabilities far below those of its dual Zener counterpart. As such, its optimal application fields are consumer electronics, telecom, and computers. Its outstanding voltage- and current- regulating capabilities, combined with its lightning-fast recovery time, make it ideal for protecting delicate circuits from voltage drops, power surges, and power shutoffs.
