1N1355

Overview

The 1N1355 is a single Zener diode manufactured by Microchip Technology, housed in the DO-203AA (DO-15) axial leaded package. It features a nominal Zener voltage of 15 V with a tolerance of ±10%. The device is rated for a maximum power dissipation of 10 W and has a maximum Zener impedance of 2 Ohms. This component is designed for robust voltage regulation applications requiring high power handling capabilities.

Feature Summary

• Provides stable voltage regulation at a fixed 15 V reference point
• Capable of dissipating up to 10 W of power for high-current applications
• Constructed in a durable DO-203AA axial leaded package for through-hole mounting

Applications

• Voltage regulation circuits
• Overvoltage protection systems
• Reference voltage sources in industrial equipment

Procurement Notes

Verify the manufacturer designation as Microchip Technology or its predecessor entities when sourcing. Confirm the package type is DO-203AA and the electrical specifications match the 15 V / 10 W rating. Ensure the part status is active if new production is required. Cross-reference datasheets from authorized distributors to confirm impedance and tolerance values.

Selection Notes

Select this component when a high-power 15 V Zener reference is needed in an axial package. Consider the 10 W power rating and thermal management requirements for the specific application environment. Verify that the ±10% voltage tolerance meets the circuit precision requirements. Compare against lower power alternatives if space or heat dissipation is constrained.

Part Context

The 1N1355 belongs to the family of standard Zener diodes used for voltage clamping and regulation. It is often associated with legacy part numbers from manufacturers like New Jersey Semiconductor Products Inc. before acquisition by Microchip Technology. The DO-203AA package provides mechanical stability for industrial environments.

Replacement Considerations

Check for equivalents such as the 1N5928B or other 15V 10W Zener diodes in the DO-203AA package. Ensure substitute parts meet the same 10 W power dissipation and 2 Ohm impedance specifications. Verify pinout compatibility and thermal characteristics before substitution.
