1N825A BK

Single Zener Diodes Overview

The Central Semiconductor Corp 1N825A BK is a temperature compensated Zener diode housed in the JEDEC DO-35 axial leaded package. It provides a nominal Zener voltage of 6.20 V at a test current of 7.5 mA, with a maximum dynamic impedance of 10 Ω and a tolerance of ±5%. The device dissipates up to 500 mW and operates within a junction temperature range of -65°C to +175°C. It exhibits a typical temperature coefficient of 0.002 %/°C and a maximum voltage stability of 19 mV over the -55°C to +100°C range.

Single Zener Diodes Feature Summary

Single Zener Diodes Procurement Notes

Verify the specific suffix 'BK' against official datasheets to confirm plating or packaging variations. Confirm RoHS compliance status as it may vary by production batch. Ensure the DO-35 package dimensions match your PCB footprint requirements before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a stable 6.2 V reference is required across wide temperature extremes. The low temperature coefficient makes it suitable for precision analog circuits where standard Zener diodes would introduce unacceptable drift. Verify that the 500 mW power dissipation rating meets your circuit's thermal constraints.
