The Central Semiconductor Corp 1N4002SP TR TIN/LEAD is a discontinued silicon rectifier diode belonging to the 1N4001 series. It features a single standard recovery configuration housed in a DO-41 through-hole package with axial leads. The device supports a maximum average forward current of 1 A and a peak repetitive reverse voltage of 100 V. It is designed for general-purpose rectification applications requiring high reliability.
This component has been officially classified as End of Life (EOL) by Central Semiconductor Corp effective June 14, 2016. No new production or procurement is possible. Verification of availability should focus on existing surplus stock from authorized distributors rather than manufacturer direct orders.
Due to the EOL status, this part number cannot be selected for new designs. Engineers must transition to alternative components that meet the required electrical specifications. Selection criteria should prioritize equivalent voltage ratings, current handling capabilities, and package compatibility to ensure circuit continuity.
The 1N4002SP variant is part of the broader 1N4001 series of 1 amp silicon rectifiers manufactured by Central Semiconductor. This series was widely utilized for its robust performance in low-frequency power conversion tasks. The specific suffixes indicate special processing or packaging configurations within the product line.
Central Semiconductor specifies 1N4007 TR as the designated replacement for the 1N4002SP TR variant.
