Product Code : SCL-EAE-14625
Indian Lab Suppliers supplies the PN Junction Diode Unit (Product ID: 14625) as part of its electrical and electronics range. It is a silicon PN junction diode mounted on a board with marked anode and cathode terminals for circuit practicals.
Quick Answer
A standard silicon diode (1N4007, 1N4148 or equivalent) is fixed to an acrylic or wooden insulated board with brass binding posts labelled anode (+) and cathode (–). In forward bias it conducts once the barrier potential of about 0.6–0.7 V is overcome; in reverse bias only a tiny leakage current flows at low laboratory voltages. One unit makes a half-wave rectifier, and two or four units are needed for full-wave or bridge rectification.

Frequently Asked Questions
Which diode is fitted?
A silicon diode such as 1N4007 or 1N4148, or equivalent.
What is the knee voltage?
About 0.6–0.7 V for silicon.
Can it do full-wave rectification alone?
No; one unit gives half-wave, full-wave needs two or four.
