1N6003B

Single Zener Diodes Overview

The Microchip Technology 1N6003B is a 500 mW Zener diode housed in an axial-lead glass DO-35 package. It provides a nominal Zener voltage of 13 V with a ±5% tolerance at a test current of 5 mA. The device exhibits a maximum dynamic impedance of 9.9 Ohms and a typical temperature coefficient of +0.075 %/°C. Maximum reverse leakage current is specified at 0.1 µA, while the maximum DC Zener current reaches 600 mA.

Single Zener Diodes Feature Summary

• Hermetically sealed glass construction for high reliability
• Internal metallurgical bonds for structural integrity
• Non-sensitive to electrostatic discharge events
• Inherently radiation hard design

Single Zener Diodes Applications

• Voltage regulation over broad operating ranges
• Reference voltage generation in precision circuits
• Overvoltage protection for sensitive components

Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as historical production involves multiple entities including Microsemi and Microchip Technology. Confirm RoHS compliance status, as commercial versions may differ from screened equivalents. Ensure the ordering suffix matches the required tolerance and screening level specifications before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a stable 13 V reference is required within a 500 mW power dissipation limit. The positive temperature coefficient makes it suitable for applications where voltage increases slightly with heat. Verify that the forward voltage drop meets circuit requirements during non-regulating states.

Single Zener Diodes Part Context

This part belongs to the JEDEC registered 1N5985 through 1N6031 series of axial-leaded Zener diodes. The series covers a wide voltage range from 2.4 to 200 volts with various tolerance options. The B suffix specifically denotes a 5% voltage tolerance standard for this family.

Single Zener Diodes Replacement Considerations

Equivalent parts include 1N6003B-1 and 1N6003BUR-1. Verify pinout compatibility and thermal resistance characteristics when substituting.
