Overview
The Microchip Technology 1N3017B-1/TR is a 1-watt Zener diode with a nominal voltage of 7.5 V and a ±5% tolerance. It operates within a temperature range of -55°C to +175°C and features a hermetically sealed DO-41 glass package. The device exhibits a maximum dynamic impedance of 4.0 Ohms at the test current of 34 mA, with a reverse leakage current of 100 µA at 5.7 V. It is qualified per MIL-PRF-19500/115 for JAN, JANTX, and JANTXV levels.
Feature Summary
- Hermetically sealed glass DO-41 package with metallurgical bonding
- Qualified per MIL-PRF-19500/115 for high-reliability applications
- Inherently radiation hard design
- Low reverse leakage currents
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 tape and reel packaging specifications against EIA-296 standards if applicable. Ensure the component meets the exact JEDEC registration requirements for the intended application environment.
Selection Notes
Select this component for designs requiring a stable 7.5 V reference in harsh environments. Consider the wide operating temperature range and radiation hardness for space or defense projects. Verify thermal derating curves for power dissipation limits above 95°C lead temperature.
Part Context
This part belongs to the 1N3016B-1 through 1N3045B-1 series of 1-watt glass case Zener diodes. The series covers a voltage range from 6.8 to 110 volts and is registered with JEDEC. It provides a robust solution for voltage regulation where reliability and environmental resistance are critical.
Replacement Considerations
Direct substitutes include other parts in the 1N3016B-1 through 1N3045B-1 series with matching voltage and tolerance. Cross-reference MIL-PRF-19500/115 qualified equivalents from other manufacturers for JAN, JANTX, or JANTXV levels.
