1N5225B_T50A

Single Zener Diodes Overview

The onsemi 1N5225B_T50A is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 3 V with a tolerance of 5%. The device has a maximum power dissipation of 500 mW and operates within a temperature range from -65 °C to +200 °C. It utilizes the DO-35 through-hole package, measuring 4.56 mm in length and 1.91 mm in width. Key electrical parameters include a maximum reverse leakage current of 50 µA and a Zener impedance of 29 Ohms at a test current of 20 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation with a nominal 3 V output.
• Capable of handling up to 500 mW of power dissipation.
• Constructed with hermetically sealed glass compression bond technology.
• Supports high-temperature operation up to 200 °C.

Single Zener Diodes Applications

• General-purpose voltage regulation circuits
• Reference voltage sources
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify the specific suffix _T50A against official manufacturer documentation to confirm tape-and-reel packaging details. Ensure compliance requirements such as RoHS and REACH are validated for the intended region. Confirm that the DO-35 through-hole package matches the target PCB footprint and assembly process specifications.

Single Zener Diodes Selection Notes

Select this component when a precise 3 V reference is required in a standard axial leaded package. Consider the 5% voltage tolerance and 29 Ohm impedance for circuit stability. Evaluate the 500 mW power rating against thermal constraints. Verify compatibility with operating temperatures up to 200 °C if used in high-heat environments.

Single Zener Diodes Part Context

This part belongs to the 1N52xx series of general-purpose Zener diodes manufactured by onsemi. These devices are widely used in electronic circuits requiring reliable voltage clamping or regulation. The series offers various voltage options within a consistent DO-35 package form factor, facilitating design standardization across different product lines.

Single Zener Diodes Replacement Considerations

Compatible substitutes include the 1N5225B from other manufacturers such as Micro Commercial Components (MCC) or Tak Cheong (TC1N5225A), provided they meet the same 3 V, 500 mW, and DO-35 package specifications.
