Frequently Asked Questions:

Q: What is the typical forward voltage drop for the 1N5248 Zener diode?
A: The typical forward voltage drop for the 1N5248 Zener diode is approximately 1.0V at a forward current of 200mA.

Q: How should the 1N5248 Zener diode be oriented for proper voltage regulation?
A: The 1N5248 Zener diode must be reverse-biased for voltage regulation. The cathode (banded end) connects to the more positive potential, and the anode connects to the more negative potential.

Q: What are the physical dimensions or lead pitch of the DO-35 package for the 1N5248?
A: The DO-35 package is a small glass axial-leaded component. Typical dimensions include a body length of approximately 3.5mm and a diameter of 1.7mm, with axial leads for through-hole mounting.

Q: Can this 1N5248 18V 500mW Zener diode replace a 1N4746A?
A: The 1N4746A is an 18V 1W Zener diode in a DO-41 package. While both offer 18V, the 1N5248 has a lower power dissipation (500mW) and a smaller DO-35 package. It may not be a direct replacement depending on power requirements and physical fit.
