1N5259C-TAP

Single Zener Diodes Overview

The Vishay General Semiconductor - Diodes Division 1N5259C-TAP is a silicon planar power Zener diode in the DO-35 (DO-204AH) axial leaded package. It provides a nominal Zener voltage of 39 V with a tight ±2 % tolerance, indicated by the 'C' suffix. The device operates at a test current of 3.2 mA and dissipates up to 500 mW. Key electrical characteristics include a maximum reverse leakage current of 0.1 µA at 25 V, a typical dynamic resistance of 80 Ω at the test current, and a temperature coefficient of +0.094 %/K.

Single Zener Diodes Feature Summary

• Tight Zener voltage tolerance of ±2% for high precision applications
• Silicon planar construction for enhanced reliability
• Low reverse leakage current for efficient operation

Single Zener Diodes Applications

• Voltage stabilization
• Reference voltage generation
• Overvoltage protection circuits

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the 'C' suffix to confirm the ±2% tolerance specification. Ensure the '-TAP' suffix matches the required taped packaging format. Cross-reference the document number 85588 for the latest technical specifications and compliance definitions before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a precise 39 V reference is required with strict tolerance limits. The DO-35 package suits through-hole designs requiring robust mechanical mounting. Evaluate the thermal resistance and ambient temperature conditions to ensure the 500 mW power dissipation limit is not exceeded during continuous operation.

Single Zener Diodes Part Context

This part belongs to the 1N5221 to 1N5267 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide range of nominal voltages from 2.4 V to 75 V. The 'C' variant specifically denotes tighter manufacturing tolerances compared to the standard 'B' version, catering to applications demanding higher accuracy.

Single Zener Diodes Replacement Considerations

Compatible substitutes within the same Vishay family include other 1N52xx series variants with matching voltage ratings. Verify that alternative components maintain the same DO-35 package dimensions and thermal characteristics to ensure physical compatibility without circuit redesign.

Single Zener Diodes FAQ
