The ultrafast recovery diode, also known as the Zener diode, is a special type of semiconductor diode,

It can maintain a stable voltage when the current or temperature changes. Below is a detailed introduction to the Zener diode:

1N5913B Zener Diode

Product Model: 1N5913B

Product Packaging: DO-41

Rated power: 1.5W

Stabilized Voltage: 3.3V ±5% Accuracy

Packaging method: Tape & Reel (TR), i.e., reel packaging, suitable for automated production lines

Main parameters:

Stable voltage: refers to the stabilized voltage generated across the terminals of a voltage regulator diode when it passes the rated current.
This value may vary slightly depending on the operating current and temperature.

Rated operating current: The operating current value corresponding to the stable and optimal voltage regulation performance of the Zener diode under prolonged operation.

Maximum dissipation power (Pz): refers to the maximum allowable power consumption of the Zener diode itself, and this limit must not be exceeded.

Dynamic resistance: The dynamic resistance of a voltage regulator diode equals the ratio of voltage change to current change.
The smaller the dynamic resistance, the better the voltage stabilization effect.
