1N5256C-TAP

Single Zener Diodes Overview

The Vishay 1N5256C-TAP is a silicon planar power Zener diode in the DO-35 (DO-204AH) axial leaded package. It provides a nominal Zener voltage of 30 V with a tight tolerance of ±2%, as indicated by the 'C' suffix. The device operates at a test current of 4.2 mA and features a maximum dynamic resistance of 49 Ω. It dissipates up to 500 mW, supports junction temperatures up to 175 °C, and exhibits a reverse leakage current of 0.1 µA at 23 V.

Single Zener Diodes Feature Summary

• High precision voltage regulation achieved through a ±2% Zener voltage tolerance
• Robust thermal stability supporting operation up to 175 °C junction temperature
• Low forward voltage drop for efficient circuit integration

Single Zener Diodes Applications

• Voltage stabilization
• Reference voltage generation
• Overvoltage protection circuits

Single Zener Diodes Procurement Notes

Verify that the specific ordering code includes the '-TAP' suffix to ensure procurement of the ammo-pack variant rather than standard reel packaging. Confirm the 'C' designation is present to guarantee the required ±2% tolerance level. Cross-reference the document revision date against your project specifications to ensure compliance with the latest manufacturing standards.

Single Zener Diodes Selection Notes

Select this component when precise voltage clamping is critical due to its narrow ±2% tolerance band. The DO-35 package is suitable for through-hole mounting where space permits. Ensure the operating current remains near the specified 4.2 mA test point to maintain optimal accuracy and minimize self-heating effects within the 500 mW dissipation limit.

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 voltages from 2.4 V to 75 V. The 1N5256 specifically targets the 30 V segment, offering a balance between low leakage and stable regulation characteristics typical of the mid-range voltage devices in this lineup.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N5256 variants or Vishay's MMSZ5256C-E3-08 in SOD-123 surface mount packages. Verify that replacement parts match the 30 V nominal voltage, ±2% tolerance, and 500 mW power rating requirements.
