1N5382CE3/TR8 Diodes - Zener - Single Application Field and Working Principle

The 1N5382CE3/TR8 is a Zener diode, specifically a single, glass-encapsulated device that performs a voltage-regulating function when connected in the reverse direction. It is typically used in circuits requiring over-voltage protection and voltage regulation, as well as other areas where a voltage reference and protection is necessary.

Structurally, the 1N5382CE3/TR8 is composed of a P-N junction, which acts as an electronic switch and is designed to be optimally placed in the forward direction when forward biasing is required. When the voltage exceeds the Zener voltage, the back-biasing causes the voltage at the anode to drop, creating a stable operating point, which limits any current increase in the circuit.

The primary application of the 1N5382CE3/TR8 is in the production of negative voltage regulators. In this application, the diode acts as a low-voltage, low-power supply for small circuits and is often used for powering application-specific integrated circuits (ASICs), transient voltage suppressors (TVS), and other circuits that require stable, low-voltage sources.

The 1N5382CE3/TR8 can also be used in reverse voltage clamping circuits, which can protect a sensitive component from an excessive and potentially damaging voltage. The device is typically used as a part of a voltage-protection circuit to deflect any voltage that is higher than the Zener breakdown voltage of the diode.

Aside from its electrical function, the 1N5382CE3/TR8 also offers some features that enhance its practical use and longevity. It features a power rating of 250mW and a thermal conductivity rating of 1.5. It has a reverse recovery time of less than 10nS and an operating temperature range of -65° C to +150° C. Additionally, its maximum reverse leakage current is 1µA and it has a Zener voltage range from 7.8V to 10V.

In general, the 1N5382CE3/TR8 is a cost-effective, reliable and efficient voltage-regulating diode. It can be used in any circuit requiring over-voltage protection and voltage regulation, as well as in reverse voltage clamping circuits. It is a simple, but effective component that offers a number of features which enhance its practical use and longevity.
