Overview
The Microchip Technology 1N3031B-1/TR is a 1-watt glass case Zener diode with a nominal voltage of 30 V and a ±5% tolerance. It operates within a temperature range of -55°C to +175°C and features a hermetically sealed DO-41 axial package. The device exhibits a maximum dynamic impedance of 40 Ohms at the test current, low reverse leakage current of 10 µA at 22.8 V, and a forward voltage of 1.2 V at 200 mA.
Feature Summary
- Hermetically sealed glass DO-41 package for high-reliability applications
- Metallurgically bonded construction with double plug design
- Qualified per MIL-PRF-19500/115 standards
Applications
- Voltage regulation over broad operating current and temperature ranges
- High-reliability military and aerospace circuits
- Radiation-hardened electronic systems
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 automated assembly requirements. Ensure the component meets the exact JEDEC registration number specifications for your design.
Selection Notes
Select this component when a 30 V reference with tight 5% tolerance is required in a through-hole glass package. Consider the metallurgical bonding and radiation hardness for demanding environments. Evaluate thermal derating curves if operating near the maximum power dissipation limits at elevated temperatures.
Part Context
This part belongs to the established 1N3016B-1 through 1N3045B-1 series of 1-watt Zener diodes. The series provides a wide selection of voltages from 6.8 V to 110 V in the same DO-41 package format. It serves as a standard solution for robust voltage regulation in industrial and defense electronics.
Replacement Considerations
Direct replacements include other 1N3031 variants with matching voltage and tolerance. Verify package compatibility and qualification levels when substituting commercial grade parts for military qualified versions.
FAQ
