1N5345BRLG

Single Zener Diodes Overview

The onsemi 1N5345BRLG is a single Zener voltage regulator diode from the 1N53 Series, housed in an axial lead DO-15 (CASE 017AA) package. It features a nominal Zener voltage of 8.7 V with a ±5% tolerance and a maximum steady-state power dissipation of 5 W at 25°C. The device operates within a junction temperature range of -65°C to +200°C and includes silicon-oxide passivated junctions for environmental protection.

Single Zener Diodes Feature Summary

• Utilizes silicon-oxide passivated junctions for enhanced stability and superior operating characteristics.
• Features void-free, transfer-molded thermosetting plastic packaging that provides corrosion resistance and solderability.
• Offers high surge current capability rated up to 180 W for an 8.3 ms pulse width.

Single Zener Diodes Applications

• Voltage regulation in electronic circuits
• Protection against transient overvoltage events
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix 'R' indicates tape and reel packaging containing 4000 units per reel. Confirm RoHS compliance status by checking the 'G' suffix designation or official material declarations. Ensure the component meets REACH SVHC requirements prior to integration into final assemblies.

Single Zener Diodes Selection Notes

Select this component when a stable 8.7 V reference is required with a 5 W power handling capacity. Consider the axial lead configuration for through-hole mounting applications. Evaluate thermal derating requirements if operating above 25°C ambient temperature to maintain reliability within specified limits.

Single Zener Diodes Part Context

This part belongs to the 1N53 Series of 5 Watt Surmetic 40 Zener Voltage Regulators. The series covers a wide Zener voltage range from 3.3 V to 200 V. All devices in this family share similar mechanical construction and electrical testing standards defined in the common datasheet.

Single Zener Diodes Replacement Considerations

Direct replacement options include other manufacturers offering equivalent 5 W axial Zener diodes with an 8.7 V nominal voltage and ±5% tolerance. Verify pinout polarity and physical dimensions match the existing design constraints before substitution.
