1N5237B_T26A

Single Zener Diodes Overview

The onsemi 1N5237B_T26A is a single silicon Zener diode designed for voltage regulation applications. It features an 8.2 V nominal Zener voltage with a 5% tolerance, tested at a current of 20 mA. The device dissipates up to 500 mW of power and exhibits a maximum dynamic impedance of 8 Ohms. It operates within a temperature range of -65°C to +200°C and utilizes the DO-35-2 through-hole package.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation via a unidirectional Zener junction
• Supports high-temperature operation up to 200°C
• Utilizes a glass-sealed DO-35 axial leaded package

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection stages
• Clipping and clamping networks

Single Zener Diodes Procurement Notes

Verify the specific T26A suffix against official documentation to confirm tape-and-reel packaging details. Confirm RoHS compliance status and REACH SVHC declarations directly with onsemi or authorized distributors before procurement.

Single Zener Diodes Selection Notes

Select this component when a precise 8.2 V regulation point is required in through-hole designs. Ensure the circuit current does not exceed limits that would cause power dissipation beyond 500 mW. Verify thermal derating requirements if ambient temperatures approach the upper operational limit.

Single Zener Diodes Part Context

This part belongs to the standard 1N52xx series of low-power Zener diodes manufactured by onsemi. These components are widely used in general-purpose electronics for basic voltage stabilization tasks where moderate precision and reliability are sufficient.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5237B parts (e.g., Microchip, MCC) ensuring identical 8.2 V, 500 mW, and DO-35 specifications. Verify pinout compatibility and thermal characteristics match the original design requirements.
