  • BZT52C Zener Diode, are a special kind of semiconductor diode which permits current to flow in the forward direction. What makes them different from other diodes is that Zener diodes will also permits current to flow in the reverse direction when its "Zener voltage" is reached.

  • ZMM Zener Diode utilize the reverse characteristics of a pn junction. ... Since this breakdown voltage is also called Zener voltage, voltage regulator diodes are also called Zener diodes. This voltage may be used as a constant voltage power supply or a reference voltage for electronic circuits.

  • BZV55B Voltage regulator diode utilize the reverse characteristics of a pn junction. ... Since this breakdown voltage is also called Zener voltage, voltage regulator diodes are also called zener diodes. This voltage may be used as a constant voltage power supply or a reference voltage for electronic circuits.

  • BZV55C Voltage regulator diode is a low-power voltage regulator diodes in small hermetically sealed glass SOD80C(MINI MELF) Surface-Mounted Device (SMD) packages.

  • BZX55B Small Signal Zener Diode is a special type of diode designed to reliably allow current to flow "backwards" when a certain set reverse voltage, known as the Zener voltage, is reached.

  • BZX55C Small Signal Zener Diod is a special type of diode designed to reliably allow current to flow "backwards" when a certain set reverse voltage, known as the zener voltage, is reached. Welcome to buy BZX55C Small Signal Zener Diode from us.
