1N3511A-1

Single Zener Diodes Overview

The Microchip Technology 1N3511A-1 is a hermetically sealed glass Zener voltage regulator diode housed in the DO-35 axial leaded package. It provides a nominal Zener voltage of 5.1 V with a tolerance of ±5%, measured at a test current (Izt) of 20 mA. The device features a maximum Zener impedance of 14 Ohms and supports a DC power dissipation of 400 mW. It operates within a junction temperature range of -65°C to +175°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass construction for environmental stability
• Axial leaded DO-35 package configuration
• Defined polarity indicated by cathode band

Single Zener Diodes Applications

• Voltage regulation circuits
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify the specific suffix '-1' against the manufacturer's official documentation, as standard datasheets may list only the base part number. Confirm that the ordering suffix does not alter electrical characteristics or packaging type. Ensure the component meets required military or industrial specifications if applicable to the design.

Single Zener Diodes Selection Notes

Select this component when a stable 5.1 V reference is required in an axial package. Consider the 14 Ohm impedance and 20 mA test current for biasing calculations. Verify thermal management requirements given the 400 mW power rating and high operating temperature limit.

Single Zener Diodes Part Context

This device belongs to the 1N3506A through 1N3534A series of 400 mW Zener diodes manufactured by Microchip Technology (formerly Microsemi). The series covers a wide voltage range from 3.3 V to 47 V, all utilizing the same DO-35 hermetic glass case and tin/lead lead finish.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' DO-35 Zener diodes with 5.1 V nominal voltage, ±5% tolerance, and equivalent power ratings. Verify pinout compatibility and thermal performance before substitution.
