Single Diodes datasheet and documents for CN4157 TR

CN4157 TR

Single Diodes Overview

The CN4157 TR is a silicon forward reference diode manufactured by Central Semiconductor Corp. It is housed in a DO-35 axial leaded package and designed for applications requiring controlled forward voltage characteristics, such as voltage regulation, sensing, and comparing. The device operates within a junction temperature range of -65°C to +150°C with a maximum power dissipation of 400 mW. Electrical specifications at 25°C include a reverse current of 10 μA maximum at 20V reverse bias. Forward voltage ranges from 1.85V to 2.05V at 1.0mA, 2.12V to 2.32V at 10mA, and 2.36V to 2.66V at 100mA.

Single Diodes Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm packaging configuration and compliance status. Ensure that the requested component matches the exact electrical tolerances and mechanical outline defined in the datasheet. Cross-reference ordering codes with authorized distributors to avoid discrepancies in marking or revision levels.

Single Diodes Selection Notes

Select this component when a stable forward voltage drop is required across varying current levels. Compare the specified forward voltage ranges at 1mA, 10mA, and 100mA against circuit requirements. Evaluate the 400mW power dissipation limit relative to thermal management constraints in the target assembly environment.

Single Diodes Part Context

This component belongs to the family of silicon forward reference diodes produced by Central Semiconductor Corp. It shares design similarities with the C1N4156 and CN5179 variants, which offer different forward voltage profiles while maintaining the same DO-35 mechanical footprint and general operational characteristics for reference applications.

Single Diodes Replacement Considerations

Direct substitutes include the C1N4156 and CN5179 from the same manufacturer series. Verify that alternative parts meet the specific forward voltage requirements of the application, as these variants exhibit distinct voltage ranges under identical test conditions.
