1N5224B_T50R

Single Zener Diodes Overview

The onsemi 1N5224B_T50R is a single-channel general-purpose Zener diode with a nominal voltage of 2.8 V and a maximum power dissipation of 500 mW. It utilizes the SOD-27 through-hole package, featuring two pins for installation. The device maintains a tight voltage tolerance of ±5% and operates within a temperature range of -65°C to +200°C. Key electrical characteristics include a test current of 20 mA, a maximum Zener impedance of 30 Ω, and a maximum reverse leakage current of 100 μA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at a nominal 2.8 V reference level
• Supports high-temperature operation up to 200°C junction temperature
• Utilizes axial leaded SOD-27 package for reliable through-hole mounting

Single Zener Diodes Applications

• Voltage reference circuits requiring low-voltage stability
• Overvoltage protection in sensitive electronic systems
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify the specific suffix _T50R against official datasheets to confirm reel packaging specifications. Ensure compatibility with standard through-hole assembly processes given the SOD-27 form factor. Cross-reference manufacturer part numbers to avoid confusion with bulk-packaged equivalents or variants from other manufacturers sharing the base 1N5224B designation.

Single Zener Diodes Selection Notes

Select this component when a precise 2.8 V regulation point is required with moderate power handling capabilities. The wide operating temperature range makes it suitable for demanding environments. Consider the 30 Ω impedance for dynamic load variations and ensure the 500 mW dissipation rating aligns with thermal management constraints in the target design.

Single Zener Diodes Part Context

This component belongs to the 1N52 series of Zener diodes, a widely recognized family for voltage regulation tasks. The 1N5224B variant specifically targets low-voltage applications near the knee region of the breakdown curve. The T50R suffix typically indicates tape-and-reel packaging for automated assembly, distinguishing it from bulk or cut-tape versions.

Single Zener Diodes Replacement Considerations

Direct substitutes include 1N5224B from other manufacturers such as Microchip Technology or Fairchild Semiconductor, provided they meet the same 2.8 V, 500 mW, and DO-35/SOD-27 specifications. Verify pinout and physical dimensions before substitution.
