1N5256C-TR

Single Zener Diodes Overview

The Vishay 1N5256C-TR is a silicon planar power Zener diode with a nominal voltage of 30 V and ±2 % tolerance. It operates in the DO-35 (DO-204AH) axial package, supporting a maximum power dissipation of 500 mW at thermal equilibrium. The device features a test current of 4.2 mA, a maximum dynamic resistance of 49 Ω, and a reverse leakage current of 0.1 µA at 23 V. Its junction temperature range spans from -65 °C to +175 °C, with a typical voltage temperature coefficient of 0.091 %/K.

Single Zener Diodes Feature Summary

• High-precision voltage regulation capability with ±2 % tolerance for stable reference applications
• Robust thermal performance allowing operation up to a 175 °C junction temperature
• Low reverse leakage current ensuring minimal power loss during non-conducting states

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify that the ordering code explicitly includes the 'C' suffix to confirm the required ±2 % tolerance specification. Ensure the procurement documentation matches the 1N5256C-TR designation to avoid receiving standard ±5 % tolerance variants. Confirm compliance with material categorization standards as defined by the manufacturer's documentation.

Single Zener Diodes Selection Notes

Select this component when circuit designs demand tight voltage accuracy within the 30 V range. The DO-35 through-hole package facilitates manual assembly or standard automated insertion processes. Evaluate the 49 Ω dynamic resistance against load regulation requirements to ensure adequate performance under varying current conditions.

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 nominal voltage spectrum from 2.4 V to 75 V. The 'C' suffix specifically denotes the tighter manufacturing tolerance compared to the standard 'B' variant.

Single Zener Diodes Replacement Considerations

Substitute only with other 1N5256C-TR units from authorized distributors. Cross-referencing with generic equivalents requires independent validation of the ±2 % tolerance and 500 mW power rating.
