Single Zener Diodes Procurement Notes

Verify the specific suffix '-TR' indicates tape and reel packaging if bulk handling is required. Confirm the manufacturer is Vishay General Semiconductor - Diodes Division, formerly known as Vishay Siliconix, to ensure correct sourcing from authorized channels. Check for RoHS compliance markings on the datasheet or ordering information.

Single Zener Diodes Selection Notes

Select this component when a 15 V reference with 1.3 W power capability is needed. Ensure the circuit design accounts for the 4 Ohm dynamic impedance for precise regulation. Verify that the DO-41 package fits the PCB layout constraints and that the thermal management supports the 1.3 W dissipation at the expected ambient temperature.

Single Zener Diodes Part Context

This part belongs to the ZPY series of silicon planar power Zener diodes. These components are engineered for high reliability in industrial and consumer electronics. The DO-41 package provides a standard form factor for through-hole assembly, widely used in legacy and new designs requiring discrete voltage regulation.

Single Zener Diodes Replacement Considerations

Consult official substitution guides for equivalent parts with matching 15 V Zener voltage, 1.3 W power rating, and DO-41 package. Verify pinout compatibility and electrical characteristics such as dynamic impedance and leakage current before replacing.
