A Zener diode is a type of diode that permits current not only in the forward direction like a normal diode, but also in the reverse direction if the voltage is larger than the breakdown voltage known as "Zener knee voltage" or "Zener voltage".
Topdiode supplies zener diodes for voltage regulation circuits as bellow:
| Power dissipation | P/N | Voltage Range | |
|---|---|---|---|
| 500mW,1/2W | BZX55C2V7~47V DO-35 | 2.7V~47V | |
| 500mW,1/2W | BZV55C2V4~47V LL-34 | 2.4V~47V | |
| 1000mW, 1W | 1N4729A~1N4756A DO-41 | 3.3V~100V | |
| 1W | ZM4728~ZM4761 LL-41 | 3.3V~100V | |
| 0.35W | BZX84C3V0-47V | 3V0~47V |
