Zener Diode – 5.1V 1W


Availability: In Stock


SKU: ELC-002 Manufacturer: Fairchild Semiconductor Mfg Part Number: 1N4733ATR Category: Tags: ,


A Zener diode works like a conventional diode up until the point you hit the breakdown voltage (the point at which the diode can no longer “hold back” the current trying to flow backwards in your circuit). A “normal” diode will allow current flow to reverse direction when the breakdown voltage is exceeded while a Zener diode allows everything over the breakdown voltage to trickle through while holding back the rated voltage. Zener diodes make great low current voltage stabilizers and reference voltages for this reason.

These specific diodes are rated at 1W and 5.1V.
