ZPY56-TR

Single Zener Diodes Overview

The ZPY56-TR is a general-purpose Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 56 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 1.3 W and operates within a junction temperature range of -55°C to +175°C. Packaged in the DO-41 axial leaded format, it utilizes through-hole mounting technology. Key electrical characteristics include a test current of 10 mA and a maximum reverse leakage current of 500 nA at the specified voltage.

Single Zener Diodes Procurement Notes

Verify the specific manufacturer part number against official Vishay documentation to ensure compatibility with design requirements. Confirm that the DO-41 package dimensions align with the intended PCB layout. Check for any specific ordering suffixes that may indicate variations in packaging or testing criteria before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 56 V regulated voltage point is required in a through-hole assembly. Ensure the circuit can accommodate the 1.3 W power rating under worst-case thermal conditions. Verify that the ±5% voltage tolerance meets the precision needs of the application, as tighter tolerances require different series variants.

Single Zener Diodes Part Context

This component belongs to the ZPY series of Zener diodes from Vishay. The series is characterized by its ability to handle significant power levels compared to smaller signal diodes. The TR suffix typically indicates reel packaging, suitable for automated insertion processes in manufacturing environments requiring consistent supply formats.

Single Zener Diodes Replacement Considerations

Consult official Vishay cross-reference guides for verified substitutes. Ensure any replacement maintains the 56 V nominal voltage, 1.3 W power rating, and DO-41 package footprint to guarantee mechanical and electrical compatibility without redesigning the host circuit.
