1N5255C-TAP

Single Zener Diodes Overview

The 1N5255C-TAP is a silicon planar power Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It provides a nominal Zener voltage of 28 V with a tight tolerance of ±2%, indicated by the 'C' suffix. The device operates in a DO-35 (DO-204AH) axial leaded package and dissipates up to 500 mW at thermal equilibrium. Electrical characteristics include a maximum dynamic impedance of 44 Ω, a reverse leakage current of 0.1 µA at 21 V, and a forward voltage of 1.1 V at 200 mA.

Single Zener Diodes Feature Summary

• High precision voltage regulation with ±2% tolerance for stable reference applications
• Robust thermal performance supporting 500 mW power dissipation at ambient temperatures up to 25 °C
• Low leakage current ensures minimal power loss during reverse bias operation

Single Zener Diodes Applications

• Voltage stabilization circuits
• Precision voltage references
• Overvoltage protection networks

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the TAP suffix to confirm the specific ammopack packaging format. Ensure the component matches the C-suffix designation for the required ±2% voltage tolerance. Cross-reference the document number 85588 to access the latest electrical specifications and mechanical dimensions before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when strict voltage accuracy is critical, as the C-suffix guarantees tighter tolerances than standard B-suffix variants. The DO-35 package is suitable for through-hole mounting where space constraints are not severe. Evaluate the 44 Ω dynamic impedance against circuit requirements to ensure adequate regulation under varying load currents.

Single Zener Diodes Part Context

This part belongs to the 1N5221 to 1N5267 series of small signal Zener diodes from Vishay Semiconductors. The series covers a wide range of nominal voltages from 2.4 V to 75 V. The 1N5255 variant specifically targets the 28 V segment, offering a balance between low leakage and manageable dynamic impedance for general-purpose regulation tasks.

Single Zener Diodes Replacement Considerations

Compatible substitutes within the same Vishay series include other 1N52xx devices with matching voltage ratings. Verify that replacement parts maintain the C-suffix for equivalent ±2% tolerance if precision is required. Alternative manufacturers may offer similar DO-35 packaged Zener diodes, but electrical parameters must be validated against the original datasheet.
