1N5246A(DO-35)

Single Zener Diodes Overview

The Microchip Technology 1N5246A(DO-35) is a 0.5 W glass axial-lead Zener diode with a nominal voltage of 16 V and a ±10% tolerance. It operates within a temperature range of -65°C to +175°C, featuring a maximum reverse current of 10 μA at 12.5 V and a zener impedance of 11.4 Ω at 0.25 mA. The device exhibits a positive temperature coefficient of +0.083 %/°C and maintains minimal capacitance for stable regulation.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation across a broad operating current and temperature range
• Features hermetically sealed DO-35 glass package with flexible axial leads
• Inherently radiation hard per MicroNote 050
• Minimal capacitance ensures stable performance in sensitive circuits

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels

Single Zener Diodes Procurement Notes

Verify the specific suffix 'A' confirms the required 10% voltage tolerance. Confirm the package style matches the DO-35 axial lead requirement. Ensure the manufacturer source aligns with project specifications, as this component originates from the Microsemi Scottsdale Division lineage now under Microchip Technology.

Single Zener Diodes Selection Notes

Select this component when a 16 V regulated reference is needed with moderate precision. The DO-35 package suits through-hole designs requiring robust mechanical mounting. Consider the positive temperature coefficient for thermal stability requirements in the target application environment.

Single Zener Diodes Part Context
