1N87A BK

Overview

The 1N87A BK is a standard germanium diode manufactured by Central Semiconductor Corp. It features a maximum DC reverse voltage of 23 V and an average rectified current of 50 mA. The device exhibits a maximum forward voltage of 250 mV at a forward current of 100 μA. It is housed in the DO-7 through-hole package and is currently classified as obsolete.

Feature Summary

Utilizes germanium semiconductor technology for standard rectification applications.

Applications

General purpose rectification circuits

Procurement Notes

Verify component authenticity due to obsolete status. Confirm datasheet alignment with original specifications. Check for RoHS compliance variations. Validate packaging type against legacy requirements. Ensure substitute availability if production continuity is required.

Selection Notes

Select based on 23 V reverse voltage and 50 mA current ratings. Consider germanium material properties for low forward voltage drop. Evaluate DO-7 package compatibility with existing PCB layouts. Assess thermal performance within specified operating temperature ranges.
