Overview
The 1N87A TR is a standard silicon rectifier diode manufactured by Central Semiconductor Corp. It features a maximum average forward rectified current of 50mA and a repetitive peak reverse voltage of 23V. The device is housed in the DO-7 axial leaded package, suitable for through-hole mounting. It operates within a junction temperature range of -65°C to +175°C. The component is supplied in tape and reel packaging to facilitate automated assembly processes.
Feature Summary
- Standard rectification capability with defined voltage and current ratings
- Axial leaded construction for reliable through-hole integration
- Wide thermal operating range for diverse environmental conditions
Applications
- General purpose rectification in low-current circuits
- Protection against reverse polarity in sensitive electronics
- Clamping applications in signal processing paths
Procurement Notes
Verify the specific suffix 'TR' confirms tape and reel packaging requirements for your manufacturing line. Ensure the DO-7 package dimensions match your PCB footprint constraints. Confirm RoHS compliance status if required by your project specifications. Cross-reference the datasheet for exact thermal derating curves before finalizing design parameters.
Selection Notes
Select this component when a small-signal rectifier with axial leads is required. The 23V rating suits low-voltage DC applications. Consider the 50mA current limit for load requirements. The DO-7 package offers robust mechanical stability for manual or semi-automated insertion. Evaluate thermal management needs based on the specified junction temperature limits.
Part Context
This part belongs to Central Semiconductor's discrete diode portfolio, focusing on standard rectification solutions. The company specializes in providing both surface mount and through-hole options for industrial and commercial sectors. The 1N87A series represents legacy standard designs maintained for compatibility in existing equipment and replacement markets.
Replacement Considerations
Check for direct equivalents such as 1N4001 variants if higher current ratings are acceptable. Verify pinout compatibility for DO-7 packages. Ensure voltage and current margins meet or exceed original design specifications. Consult manufacturer substitution guides for verified cross-references.
