Overview
The Central Semiconductor Corp 1N485B TR is a low leakage silicon rectifier diode housed in the DO-35 axial leaded case. This component has been officially classified as End of Life (EOL) by the manufacturer, indicating that production has ceased and no further units are being manufactured. The 'TR' suffix denotes that the device was supplied in tape and reel packaging for automated surface mount or through-hole assembly processes.
Feature Summary
- Constructed from silicon material to ensure stable electrical performance
- Designed specifically for applications requiring low reverse leakage current characteristics
- Utilizes the standard DO-35 glass axial package configuration
Applications
- General purpose rectification circuits
- Low leakage signal processing applications
- Electronic assemblies utilizing legacy component designs
Procurement Notes
This specific part number is discontinued and unavailable for new procurement. The manufacturer has transitioned the item to End of Life status with no designated replacement part numbers provided. Buyers must verify current availability through authorized distributors, though supply is limited to existing stock only. Engineering support may assist in locating alternate sources if necessary.
Selection Notes
Designers should avoid selecting this component for new hardware developments due to its discontinued status. The lack of an official replacement part number necessitates a complete redesign or the selection of a modern equivalent with verified long-term availability. Existing inventory should be managed carefully to prevent future supply chain disruptions.
Part Context
Central Semiconductor Corp specializes in discrete semiconductor products, including diodes and transistors. The company maintains a portfolio of standard and legacy devices, often continuing production of obsolete parts upon request. However, the 1N485B series represents a specific instance where demand levels fell below sustainability thresholds, leading to formal discontinuation.
Replacement Considerations
No direct replacement part numbers are listed in the official documentation. Customers are advised to contact [email protected] for assistance in identifying suitable alternative components from other manufacturers.
