JAN1N6316CUS

Single Zener Diodes Overview

The JAN1N6316CUS is a military-qualified Zener voltage regulator diode from the 1N6309US through 1N6355US series, manufactured by Microchip Technology. It features a surface-mount B-SQ MELF package with a nominal Zener voltage of 4.7 V and a tight tolerance of ±2%. The device operates within a junction temperature range of -65°C to +175°C and dissipates up to 0.5 W at an end cap temperature of 150°C. Key electrical characteristics include a maximum reverse leakage current of 5 µA at 25°C, a dynamic impedance of 17 ohms at the test current of 20 mA, and a forward voltage of 1.4 V at 1.0 A.

Single Zener Diodes Feature Summary

• Hermetically sealed voidless hard glass construction with tungsten slugs for high reliability
• Internal metallurgical bonds ensuring robust performance in critical applications
• Surface mount equivalent to JEDEC registered axial leaded packages
• Inherently radiation hard and non-sensitive to electrostatic discharge

Single Zener Diodes Applications

• High-reliability aerospace systems where failure cannot be tolerated
• Military electronic circuits requiring strict voltage regulation
• Radiation-hardened environments utilizing inherent hardness properties
• Compact surface mount designs replacing traditional axial components

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required reliability level and RoHS compliance status. Confirm the package type corresponds to the B-SQ MELF format rather than the axial DO-35 variant. Ensure procurement channels are authorized for military-grade components subject to MIL-PRF-19500/533 standards. Check for any specific lot traceability requirements mandated by the application environment.

Single Zener Diodes Selection Notes

Select this component when a surface-mount form factor is required without compromising the hermetic sealing and reliability of traditional axial Zener diodes. The ±2% tolerance makes it suitable for precision voltage reference applications. Consider the thermal resistance values when designing heat dissipation strategies for dense PCB layouts. Verify that the operating voltage range aligns with the 4.7 V nominal specification and associated knee characteristics.

Single Zener Diodes Part Context

This part belongs to the industry-recognized 1N6309 through 1N6355 series of 0.5-watt Zener voltage regulators. The series offers extensive selections ranging from 2.4 to 200 volts with various tolerance options. It serves as the surface-mount counterpart to the widely used axial-leaded versions, maintaining identical electrical performance and qualification levels while adapting to modern assembly techniques.

Single Zener Diodes Replacement Considerations

Direct replacements include other JANTXV or JANS qualified parts within the same 1N63xx series family if voltage and tolerance match. Surface-mount equivalents must maintain the B-SQ MELF package dimensions. Axial DO-35 versions like JAN1N6316C offer identical electrical specs but require different board layout considerations.
