1N4617UR

Single Zener Diodes Overview

The Microchip Technology 1N4617UR is a 0.5 W Zener voltage regulator diode designed for surface-mount applications. It features a nominal Zener voltage of 2.4 V with a standard tolerance of ±5%. The device utilizes a metallurgically bonded glass construction within the DO-213AA (MELF) package, ensuring robust performance in harsh environments. Qualified under MIL-PRF-19500/435, it supports a wide operating temperature range from -65°C to +175°C and includes an internal metallurgical bond option identified by the '-1' suffix.

Single Zener Diodes Feature Summary

• Metallurgically bonded glass surface mount construction for enhanced reliability
• Qualified per MIL-PRF-19500/435 for high-reliability military applications
• Wide operating temperature range suitable for extreme environmental conditions

Single Zener Diodes Applications

• Military avionics systems requiring high-reliability voltage regulation
• Spacecraft electronic subsystems demanding radiation hardness and stability
• Harsh environment industrial control circuits

Single Zener Diodes Procurement Notes

Verify the specific qualification level (JAN, JANTX, JANTXV, or JANS) required for your application, as availability varies by grade. Confirm the presence of the internal metallurgical bond via the '-1' suffix in the part number. Ensure compliance with MIL-PRF-19500/435 standards if mission-critical reliability is mandated. Check for RoHS status, as military grades may differ from commercial equivalents.

Single Zener Diodes Selection Notes

Select this component when a 2.4 V reference is needed in a compact surface-mount form factor. The DO-213AA package offers thermal and mechanical advantages over axial leads. Consider the -1 suffix for internal bonding requirements. Evaluate the ±5% tolerance against circuit sensitivity needs. Compare against other voltages in the 1N4614-1 through 1N4627-1 series if alternative regulation levels are viable.

Single Zener Diodes Part Context

This device belongs to the 1N4614-1 through 1N4627-1 series of 0.5 W Zener diodes. These components share common characteristics including the DO-213AA MELF package and metallurgical bonding technology. They are engineered to provide stable voltage regulation across a broad spectrum of military and aerospace applications where traditional packages are unsuitable due to size or ruggedness constraints.

Single Zener Diodes Replacement Considerations

Substitutes must match the 2.4 V Zener voltage, 0.5 W power rating, and DO-213AA package. Verify that any replacement also meets MIL-PRF-19500/435 qualifications if the original was specified for military use. Ensure the replacement maintains the internal metallurgical bond feature if present in the original design.
