Applications

1:Voltage Clamping andamp; Over-Voltage Protection: Used to protect sensitive input pins of integrated circuits (ICs) or MOSFETs from damage caused

by electrostatic discharge (ESD), voltage spikes, or accidental over-voltage.

2andldquo;Voltage Reference: Provides a simple, stable reference voltage for circuits like ADCs (Analog-to-Digital Converters), DACs (Digital-to-Analog

Converters), or voltage comparators.

3:Waveform Clipping: Converting sine waves or other waveforms into approximate square waves.

4:Power Supply Regulation: Acts as a simple voltage regulator in low-current, non-precision power supply circuits.

Description

1:Zener Voltage:

Nominal Value: 15V

This is a key parameter indicating its stable reference voltage. In practical application, it has a tolerance range.

For the BZX84C15LT3G, the Zener voltage tolerance is andplusmn;5%. This means under specific test conditions, its actual regulating voltage typically falls

between 14.25V and 15.75V.

2:Power Dissipation:

Maximum Continuous Power Dissipation: 350 mW

This is an important limit determining the maximum power the diode can safely handle (Power = Zener Voltage andtimes; Zener Current). Circuit design

must ensure the operating current does not cause the power dissipation to exceed this value, otherwise the diode may overheat and be damaged.

3:Package:

SOT-23

This is a very common 3-pin small surface mount package suitable for high-density PCB design.

4:Technology:

Single Chip: Unlike some dual-diode packages, the SOT-23 package of the BZX84C15LT3G contains only a single Zener diode.

5:Performance Characteristics:

Very Sharp Breakdown Characteristic: Indicates good voltage regulation performance.

Low Leakage Current: The reverse leakage current is very small when the voltage is below the Zener voltage.

Low Impedance: Features good dynamic response characteristics.
