1N5345BRL

Single Zener Diodes Overview

The onsemi 1N5345BRLG is a 5 Watt Zener diode from the 1N53 Series, housed in an axial lead Surmetic 40 (CASE 017AA) plastic package. It features silicon-oxide passivated junctions and provides a nominal reverse Zener voltage of 8.7 V with a ±5% tolerance range spanning 8.27 V to 9.14 V at a test current of 150 mA. The device exhibits a maximum Zener impedance of 2 ohms at IZT and maintains a maximum reverse leakage current of 10 µA at 9.5 V. It supports a maximum DC regulator current of 545 mA and withstands up to 180 W surge power for 8.3 ms pulses. Operating temperatures extend from -65°C to +150°C under DC conditions.

Single Zener Diodes Feature Summary

• Voltage reference applications
• Over-voltage protection systems

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required packaging configuration. The 'RL' designation indicates tape and reel supply, whereas 'G' denotes Pb-Free status. Confirm the specific part number against the manufacturer's official documentation to ensure correct component selection and compliance with RoHS directives before procurement.

Single Zener Diodes Selection Notes

Select this component when a 5 Watt axial Zener diode with an 8.7 V nominal breakdown is required. Ensure the application accounts for the thermal resistance characteristics and derating requirements above 25°C. Verify that the circuit design accommodates the specified maximum surge current and operates within the defined temperature range for reliable performance.

Single Zener Diodes Part Context

This device belongs to the 1N53xxB series of 5 Watt Zener Voltage Regulators manufactured by onsemi. The series covers a broad voltage spectrum from 3.3 V to 200 V, all sharing the same mechanical Surmetic 40 axial lead package. These components are designed for robust operation in common environmental conditions while maintaining precise voltage regulation capabilities.

Single Zener Diodes Replacement Considerations

Consult the manufacturer's datasheet for direct cross-reference options within the 1N53 series or equivalent JEDEC registered devices. Ensure any substitute maintains the 5 Watt power dissipation rating, axial lead form factor, and compatible voltage tolerance specifications.
