1N5916BUR-1

Diodes - Zener - Single

The 1N5916BUR-1 is one of the latest additions to the popular 1N59xxB series of Zener diodes. As a member of the Zener diode family, this particular device is invaluable to countless design engineers, given its wide range of applications. Let’s take a look at the 1N5916BUR-1’s application fields and its inner workings.

Application Fields

The 1N5916BUR-1 is primarily used as a voltage clamping device to protect expensive and sensitive components, such as integrated circuits and transistors, from voltage spikes. It can also be used to regulate the output of a power supply to ensure consistent current levels for the full range of supply voltages. This makes the 1N5916BUR-1 a great choice for applications in automotive and industrial electronics.

Working Principle

The 1N5916BUR-1 is based on the principle of the reverse breakdown of a junction diode. The diode is designed to operate in the reverse-biased condition, where the voltage across it exceeds a certain threshold known as the Zener breakdown voltage. In this state, the diode enters a region of reverse saturation, and a breakdown current starts running through it. This current is known as the Zener current, and it determines the voltage at which the diode will operate.

The junction temperature of the 1N59xxB series is maintained at 25°C, and their maximum working power is not exceed 350mW. The Zener voltage is also tightly regulated and typically ranges from 3V to 23V, with tolerances ranging from +/-2% to +/-5%. The 1N5916BUR-1 is rated at 600W, with a peak reverse voltage of 16V, making it ideal for applications that require tight voltage tolerance or over-voltage protection.
