1N5223B_T50R

Single Zener Diodes Overview

The onsemi 1N5223B_T50R is a single-channel silicon planar Zener diode designed for voltage regulation and reference applications. It features a nominal Zener voltage of 2.7 V with a tight tolerance of ±5%. The device is rated for a maximum power dissipation of 500 mW at 25°C ambient temperature. It utilizes the DO-35 axial through-hole package, measuring approximately 4.56 mm in length and 1.91 mm in diameter. Key electrical characteristics include a maximum reverse leakage current of 100 µA at 1 V and a maximum Zener impedance of 30 Ω at the test current of 20 mA. The component supports an operating junction temperature range from -65°C to +200°C.

Single Zener Diodes Feature Summary

Single Zener Diodes Procurement Notes

Verify the specific suffix _T50R against official datasheets to confirm reel packaging specifications and tape dimensions. Ensure compatibility with automated assembly equipment by checking feed orientation and leader/trailer requirements. Confirm RoHS compliance status and material declarations prior to integration into environmentally regulated products.

Single Zener Diodes Selection Notes

Select this component when a low nominal voltage of 2.7 V is required with high precision. The ±5% tolerance makes it suitable for applications demanding tighter voltage control than standard ±10% variants. Consider the DO-35 package constraints regarding board space and thermal dissipation capabilities relative to the 500 mW rating.

Single Zener Diodes Part Context

This part belongs to the 1N52 series of general-purpose Zener diodes manufactured by onsemi. The series offers a wide range of voltage values from 2.4 V to 200 V. The 'B' suffix indicates a ±5% voltage tolerance, distinguishing it from standard tolerance versions. The device represents a legacy but widely used discrete semiconductor solution for fundamental circuit protection tasks.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N5223B parts with identical DO-35 packaging and 2.7 V / 500 mW ratings. Verify that alternative sources maintain the same ±5% tolerance and electrical parameters such as Zener impedance and leakage current to ensure circuit performance consistency.
