Single Zener Diodes Procurement Notes

Verify the specific manufacturer designation when sourcing, as Central Semiconductor also produces a part designated 1N4618 BK TIN/LEAD with identical electrical parameters but different branding. Confirm that the required component is sourced from Microchip Technology rather than other manufacturers offering equivalent specifications under the same standard number.

Single Zener Diodes Selection Notes

Select this component for low-voltage regulation tasks requiring high thermal stability. The 250 mW power rating suits low-current applications. Ensure the circuit design accommodates the 1.5 kΩ Zener impedance and 1 µA leakage current limits to maintain accuracy. The wide temperature range supports demanding environmental conditions.

Single Zener Diodes Part Context

This component belongs to the standard Zener diode family used for precise voltage control. It serves as a fundamental passive element in analog and digital circuits where a fixed potential is required. The DO-35-2 form factor allows for easy integration into through-hole PCB layouts.
