JAN1N3044B-1/TR

Single Zener Diodes Overview

The JAN1N3044B-1/TR is a 1-watt glass case Zener diode qualified per MIL-PRF-19500/115. It features a hermetically sealed DO-41 package with metallurgically bonded construction and double plug design. The nominal Zener voltage is 100 volts at a test current of 2.5 mA, with a maximum dynamic impedance of 350 ohms. Maximum reverse leakage current is 10 µA at 76.0 volts. Operating junction temperature ranges from -55°C to +175°C.

Single Zener Diodes Feature Summary

• Metallurgically bonded construction with double plug design
• Inherently radiation hard
• Low reverse leakage currents

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature range
• High-reliability military and aerospace circuits
• Radiation-hardened electronic systems

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's nomenclature guide to confirm tape and reel packaging availability. Ensure the required reliability level (JAN) matches the procurement specification. Confirm RoHS compliance status if applicable, as it may vary by grade. Validate that the DO-41 axial lead form factor aligns with the target PCB layout requirements.

Single Zener Diodes Selection Notes

Select this component when a 100V breakdown voltage is required in a ruggedized axial package. Consider the 350-ohm dynamic impedance for circuit stability. Evaluate thermal derating curves for power dissipation limits above ambient temperatures. Verify that the 10µA leakage current meets system noise or standby power constraints.

Single Zener Diodes Part Context

This device belongs to the 1N3016B-1 through 1N3045B-1 series of 1-watt Zener diodes. The series covers a voltage range from 6.8V to 110V in the same DO-41 glass package. It is available in JAN, JANTX, and JANTXV qualification levels. Commercial versions are also offered in surface mount packages.

Single Zener Diodes Replacement Considerations

Equivalent parts include JAN1N3044B-1 without the trailing slash TR if bulk packaging is acceptable. Other manufacturers producing MIL-PRF-19500/115 compliant 1N3044 devices may serve as substitutes if mechanical dimensions and electrical tolerances match.
