1N5230B_T50A

Single Zener Diodes Overview

The onsemi 1N5230B_T50A is a single silicon Zener diode designed for voltage regulation applications. It features an 85 V nominal Zener voltage with a 5% tolerance, tested at 1.5 mA. The device operates in a DO-35-2 through-hole package and dissipates up to 500 mW of power. Key electrical characteristics include a maximum reverse leakage current of 100 nA and a Zener impedance of 330 Ohms. It supports a wide operating temperature range from -65 °C to +200 °C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass construction for environmental protection
• High thermal stability with extended junction temperature capability
• Low noise operation suitable for sensitive circuits

Single Zener Diodes Applications

• Voltage reference standards
• Overvoltage protection circuits
• Clamping applications in signal processing

Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as this part number appears associated with onsemi/Fairchild branding but may be sourced from licensed manufacturers like Tak Cheong. Confirm the exact suffix '_T50A' matches your required packaging format, typically Ammo Pack. Ensure compliance with RoHS directives if required by your assembly process, noting that some variants may differ in lead content.

Single Zener Diodes Selection Notes

Select this component when a precise 85 V regulation point is required in a standard axial leaded package. The high maximum operating temperature of 200 °C distinguishes it from standard commercial grade parts. Consider the 330 Ohm impedance for dynamic load requirements. Verify availability status, as supply chain data indicates potential discontinuation or limited stock for this specific marking code.

Single Zener Diodes Part Context

This device belongs to the 1N5268B series within the broader 1N52xx family of 500 mW Zener diodes. It utilizes planar die construction within a JEDEC registered DO-35 (DO-204AH) glass envelope. The 'B' suffix denotes the 5% voltage tolerance class, while the '_T50A' suffix specifies the tape and reel or ammo pack packaging configuration for automated assembly.

Single Zener Diodes Replacement Considerations

Direct substitutes include other 85 V, 500 mW, DO-35 Zener diodes such as the 1N5268B from various manufacturers. Ensure replacement parts match the 330 Ohm impedance and 100 nA leakage specifications. Verify hermetic sealing requirements are met if replacing with non-hermetic equivalents.
