1N5268B BK

Single Zener Diodes Overview

The Central Semiconductor Corp 1N5268B BK is a silicon planar Zener diode in the DO-35 axial through-hole package. It provides a nominal Zener voltage of 82 V with a ±5% tolerance, operating within a range of 77.90 V to 86.10 V at a test current of 1.5 mA. The device dissipates up to 500 mW and maintains a maximum reverse leakage current of 0.1 µA at 62 V. Electrical characteristics include a maximum Zener impedance of 330 Ω at the test current and 2000 Ω at 0.25 mA. It operates across a junction temperature range of -65°C to +200°C.

Single Zener Diodes Procurement Notes

Verify component authenticity by checking manufacturer markings against datasheet codes. Confirm ordering suffixes match required plating specifications, as these define material composition rather than electrical function. Request official documentation to validate compliance with RoHS or REACH standards before integration into production workflows.

Single Zener Diodes Selection Notes

Select this component when an 82 V Zener reference is required in a compact axial package. Ensure circuit design accommodates the specific 330 Ω dynamic impedance at nominal current. Verify that the 500 mW power dissipation rating aligns with expected thermal loads and ambient operating temperatures to maintain long-term reliability.
