1N4099D-1

Single Zener Diodes Overview

The Microchip Technology 1N4099D-1 is a 6.8 V Zener voltage regulator with a ±1% tolerance, housed in an axial-lead glass DO-35 (DO-204AH) package. It features a rated average power dissipation of 0.5 W and operates within a junction temperature range of -65°C to +175°C. The device exhibits a maximum Zener impedance of 200 Ohms at a test current of 250 µA, with a reverse leakage current of 1 µA at 5.2 V. Its noise density is specified at 40 µV/√Hz, and it possesses a positive temperature coefficient of +0.060 %/°C.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix 'D' confirms the 1% voltage tolerance requirement. Confirm that the RoHS compliance status aligns with project specifications, as this level may differ from commercial grades. Ensure the procurement channel supports the required military qualification levels and lead times associated with this component series.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is critical due to its tight 1% tolerance. The internal metallurgical bond and radiation hardness make it suitable for harsh environments. Consider the thermal resistance and derating curves for power dissipation management in enclosed spaces or high ambient temperatures.

Single Zener Diodes Part Context
