Frequently Asked Questions:

Q: What is the polarity of the 1N4746 Zener diode?
A: The 1N4746 Zener diode has a cathode band indicating the negative terminal. Current flows from cathode to anode when reverse biased at the Zener voltage.

Q: Can this 18V Zener diode replace a 15V Zener diode?
A: Replacing an 18V Zener diode with a 15V Zener diode will alter the regulated voltage level in the circuit. Ensure the replacement matches the required Zener voltage for proper circuit function.

Q: What is the typical lead pitch for a DO-41 package?
A: The DO-41 package is an axial lead component. The lead pitch is determined by the specific PCB layout and mounting requirements, not a fixed package dimension.
