Zener Diodes
As a China diode manufacturer, we supply a full range of Zener diodes for voltage regulation and circuit protection in electronic systems. Our product range covers multiple voltage levels, power ratings, and package types to support both standard applications and volume production requirements.
Zener diodes are widely used to stabilize voltage, protect sensitive components, and provide reference voltage in circuits. For customers sourcing from a reliable Zener diode manufacturer, we support consistent product performance and stable supply for long-term cooperation.
For buyers looking for wholesale Zener diode in stock, standard voltage ranges and common packages are available to support fast sourcing and ongoing production needs.
Zener Diode Product Range
Low-Power SMD and Small-Signal Zener Diodes
These compact Zener diodes are suitable for voltage reference, signal clamping and low-power regulation on space-constrained PCBs.
Available series include:
MSZ52XXS Series SOD-323 Zener Diodes
LL55C and MCL52C Series SOD-80 Zener Diodes
BZX84C Series SOT-23 and SOT-323 Zener Diodes
MMSZ52 Series SOD-123 Zener Diodes
BZT52 Series SOD-323 Zener Diodes
Common applications include portable electronics, sensor circuits, control boards, communication modules, power-management circuits and compact consumer devices.
0.5W to 1W General-Purpose Zener Diodes
General-purpose Zener diodes are widely used in power supplies, appliances, industrial controls and electronic equipment requiring voltage stabilization or a fixed reference voltage.
Available series include:
BZX55C Series 0.5W Zener Diodes
1N52 Series DO-35 Zener Diodes
DL47 and ZM47 Series 1W Zener Diodes
1N4728A to 1N4761A Series 1W Zener Diodes
DL4728A to DL4761A Series SMD Zener Diodes
Through-hole and surface-mount alternatives can be evaluated according to PCB layout, assembly method, heat dissipation and replacement requirements.
2W to 3W Zener Diodes
Higher-power Zener diodes are intended for circuits with greater continuous power dissipation or stronger voltage-clamping requirements.
Available series include:
ZY Series 2W Zener Diodes
BZX2C Series 2W Zener Diodes
2EZ Series 2W Zener Diodes
3EZ Series 3W Zener Diodes
These devices are commonly considered for industrial power circuits, control equipment, power modules and applications where lower-power devices do not provide sufficient thermal margin.
5W High-Power Zener Diodes
The 1N5333B to 1N5388B Series provides higher power capability for voltage regulation and controlled clamping applications.
A higher wattage rating does not automatically make a Zener diode suitable for every high-energy event. Continuous dissipation, pulse duration, board temperature, mounting conditions and derating must still be evaluated.
