1N3032B-1/TR

Overview

The Microchip Technology 1N3032B-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 tungsten slugs and metallurgically bonded construction. The nominal Zener voltage is 33 V at a test current of 7.5 mA, with a maximum dynamic impedance of 45 Ohms. Voltage tolerance is 5%, and the maximum reverse leakage current is 10 µA. Operating temperature ranges from -55°C to +175°C.

Feature Summary

• Hermetically sealed glass DO-41 package with tungsten heat slug for thermal stability
• Metallurgically bonded double plug construction
• Qualified per MIL-PRF-19500/115 military standards
• Inherently radiation hard

Applications

• Voltage regulation over broad operating current and temperature ranges
• High-reliability electronic applications
• Radiation-hardened circuit designs

Procurement Notes

Verify that the specific ordering suffix matches the required qualification level (JAN, JANTX, or JANTXV) and RoHS compliance status. Confirm the tape and reel packaging configuration aligns with manufacturing requirements. Ensure the component meets the intended environmental specifications for the target application.

Selection Notes

Select this component for applications requiring high reliability and radiation hardness. The 5% voltage tolerance suits general regulation needs. Consider the 1-watt power dissipation limit and thermal derating curves for proper heat management in the final assembly design.

Part Context

This part belongs to the 1N3016B-1 through 1N3045B-1 series of 1-watt Zener diodes. The series offers a wide selection of voltages from 6.8 to 110 volts in the same DO-41 package format. It provides a well-established solution for robust voltage reference and regulation tasks.

Replacement Considerations

Check equivalent parts within the 1N30xxB-1 series for different voltage ratings. Verify compatibility with MIL-PRF-19500/115 qualifications if military-grade performance is required.
