1N5231BTR

Single Zener Diodes Overview

The onsemi 1N5231BTR is a single-channel general-purpose Zener diode with a nominal voltage of 5.1 V and a maximum power dissipation of 500 mW. It features a 5% tolerance, operates within a temperature range of -65°C to +200°C, and utilizes an axial lead SOD-27 package for through-hole mounting.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at a nominal 5.1 V level
• Operates reliably across a wide thermal range from -65°C to +200°C
• Utilizes a hermetically sealed glass axial lead package

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• General purpose voltage regulation

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm shipping format. The 'TR' designation indicates tape and reel packaging, which differs from bulk bag configurations found in standard variants. Ensure compatibility with automated assembly processes requiring this specific reel format.

Single Zener Diodes Selection Notes

Select this component when a precise 5.1 V reference is required alongside high thermal stability. The 500 mW rating supports moderate current applications, while the wide operating temperature range suits demanding environments. Verify that the axial lead form factor aligns with the target printed circuit board layout constraints.

Single Zener Diodes Part Context

This device belongs to the 1N5221B through 1N5252B series of Zener diodes manufactured by onsemi. The series offers a broad selection of voltages ranging from 2.4 V to 24.0 V, all housed in the same DO-35 (SOD-27) glass axial lead package. This specific part represents the 5.1 V variant within that standardized lineup.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering the 1N5231B specification. Verify that substitute components match the 5.1 V nominal voltage, 500 mW power rating, and 5% tolerance to ensure functional equivalence in existing designs.
