1N965B

Single Zener Diodes Overview

The onsemi 1N965B is a single silicon Zener diode housed in a DO-35 glass axial leaded package. It provides a nominal Zener voltage of 15V with a tolerance of ±5%. The device dissipates up to 500 mW at a lead temperature of 75°C, derating by 4.0 mW/°C above this threshold. Electrical characteristics include a maximum dynamic impedance (ZZ) of 8.5 Ω and a knee impedance (ZZK) of 700 Ω. Maximum reverse leakage current is specified at 5 μA. The component operates within a junction and storage temperature range of -65°C to +200°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation through controlled Zener breakdown characteristics
• Features low dynamic impedance for effective noise suppression in power lines
• Constructed with a glass encapsulated DO-35 case for thermal stability
• Capable of operation across an extended industrial temperature range

Single Zener Diodes Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in electronic assemblies
• Clamping applications for transient signal suppression

Single Zener Diodes Procurement Notes

Verify the manufacturer origin, as Fairchild Semiconductor was acquired by onsemi. Confirm that the specific lot matches the requested revision level. Ensure compliance with RoHS directives if required by the end application. Check for any specific marking codes corresponding to the production date code.

Single Zener Diodes Selection Notes

Select this component when a 15V regulation point is required with tight tolerance limits. The DO-35 package suits through-hole mounting constraints. Evaluate the 500 mW power dissipation against expected circuit loads. Consider the operating temperature range for environmental suitability.

Single Zener Diodes Part Context

This device belongs to the 1N957B through 1N979B series of Zener diodes manufactured by Fairchild Semiconductor, now part of onsemi. The series covers a wide voltage spectrum from approximately 6.4V to 53.2V. These components are standardized discrete semiconductors designed for general-purpose voltage regulation tasks.

Single Zener Diodes Replacement Considerations

Substitutes must match the 15V nominal voltage, 5% tolerance, and DO-35 package. Verify equivalent power dissipation ratings and impedance specifications. Cross-reference with other manufacturers offering standard 1N965B equivalents.
