1N5260B-T50A

Single Zener Diodes Overview

The onsemi 1N5260B-T50A is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 43 V with a tolerance of ±5%. The device operates in a through-hole DO-35 axial leaded package, supporting a maximum power dissipation of 500 mW at ambient temperatures up to 75°C. Key electrical characteristics include a maximum reverse leakage current of 100 nA and a Zener impedance of 93 Ohms. It is tested at a current of 3 mA and functions within an operating temperature range from -65°C to +200°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a single unidirectional silicon junction.
• Utilizes a hermetically sealed glass axial-lead package for environmental protection.
• Maintains low reverse leakage current for efficient standby operation.

Single Zener Diodes Applications

• General-purpose voltage reference circuits
• Overvoltage protection stages
• Biasing networks in analog signal processing

Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as the 1N5260B series is produced by multiple vendors including Diodes Incorporated and Microchip Technology. Confirm that the T50A suffix corresponds to the intended Ammo Pack packaging configuration. Ensure compliance with RoHS3 standards if required for the target assembly process. Check for obsolescence status or lifecycle announcements before finalizing component selection.

Single Zener Diodes Selection Notes

Select this component when a precise 43 V reference is needed in a standard DO-35 form factor. Consider the 93 Ohm dynamic impedance for noise sensitivity requirements. Verify thermal derating calculations for environments exceeding 75°C. Compare against alternative manufacturers' equivalents if supply chain diversification is necessary.

Single Zener Diodes Part Context

This part belongs to the widely recognized 1N52xxB series of 500 mW Zener diodes. These components are standardized across the industry for general voltage regulation tasks. The 'B' suffix typically denotes a 5% voltage tolerance, distinguishing it from looser tolerance variants. The DO-35 package remains a common choice for through-hole PCB designs requiring robust axial leads.
