JAN1N3042C-1/TR

Single Zener Diodes Overview

The JAN1N3042C-1/TR is a hermetically sealed Zener diode with an 82 V nominal voltage and ±2% tolerance. It operates in the DO-41 glass axial package, rated for 1 W DC power dissipation at temperatures below +65 °C. The device supports a junction temperature range of -55 °C to +175 °C and features low reverse leakage current. Qualified per MIL-PRF-19500/115, it provides high-reliability voltage regulation suitable for demanding environments.

Single Zener Diodes Feature Summary

• High-reliability military and aerospace electronic circuits
• Radiation-hardened system protection

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required qualification level and packaging format. Confirm RoHS compliance status if applicable, as this attribute varies by commercial grade availability. Ensure the supplier documentation explicitly references the MIL-PRF-19500/115 standard for JAN-level devices before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a precise 82 V reference with tight tolerance is required in a through-hole configuration. The DO-41 package offers robust mechanical stability for axial mounting. Consider the thermal derating curve for applications where ambient temperatures exceed +65 °C to maintain safe power dissipation limits within the specified junction temperature range.

Single Zener Diodes Part Context

This part belongs to the established 1N3016B-1 through 1N3045B-1 series of 1 Watt glass case Zener diodes. The series covers a wide voltage spectrum from 6.8 V to 110 V. The JAN1N3042C-1 variant specifically targets the 82 V segment with enhanced manufacturing controls defined by the JANTX reliability classification.

Single Zener Diodes Replacement Considerations

Cross-reference other manufacturers' 1N3042 equivalents. Verify that substitute parts meet the same MIL-PRF-19500/115 qualification requirements and possess identical DO-41 package dimensions for direct mechanical interchangeability.
