1N4703RL

Single Zener Diodes Overview

The Motorola 1N4703RL is a unidirectional voltage regulator diode constructed from silicon. It operates within the DO-204AH package, also identified as DO-35, featuring a hermetically sealed glass body and two pins. The device has a maximum power dissipation of 0.5 W and a nominal reference voltage of 16 V with a tolerance of 5%. It supports an operating temperature range from -65 °C to 200 °C.

Single Zener Diodes Procurement Notes

Verify the specific manufacturer origin, as the 1N4703RL designation may be produced by multiple vendors including Motorola/NXP or others like SynSemi. Confirm that the component matches the DO-35/DO-204AH package dimensions and hermetic sealing requirements specified in the technical data before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 16 V zener voltage with 0.5 W power handling is required in a through-hole glass package. Ensure the application environment accommodates the high maximum operating temperature of 200 °C. Verify polarity markings, as the cathode is typically indicated by a color band on the glass surface.

Single Zener Diodes Part Context

This part belongs to the standard 1N47xx series of silicon zener diodes manufactured by Motorola (now NXP). These devices are widely used in general-purpose electronics for stable voltage reference and protection. The RL suffix typically denotes a reel packaging format for automated assembly processes.

Single Zener Diodes FAQ

How is the polarity of the 1N4703RL indicated?

The cathode is indicated by a color band on the external glass surface. When operated in zener mode, the cathode will be positive with respect to the anode.

What is the maximum lead temperature for soldering?

The maximum lead temperature for soldering purposes is 230 °C, applied for 10 seconds at a distance of 1/16 inch from the case.
