1N5257C-TAP

Single Zener Diodes Overview

The Vishay 1N5257C-TAP is a silicon planar power Zener diode in the DO-35 (DO-204AH) glass axial package. It provides a nominal Zener voltage of 33 V with a tight ±2% tolerance, indicated by the 'C' suffix. The device operates at a test current of 3.8 mA and dissipates up to 500 mW. Key electrical characteristics include a maximum reverse leakage current of 0.1 µA at 25 V and a typical dynamic resistance of 58 Ω at the test current.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for robust voltage regulation
• Offers high precision with a ±2% Zener voltage tolerance
• Constructed in a hermetically sealed glass DO-35 axial leaded package

Single Zener Diodes Applications

• Voltage stabilization circuits
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the -TAP suffix to confirm the specific ammopack tape configuration. Ensure the required tolerance matches the 'C' designation for ±2% accuracy rather than the standard 'B' variant. Confirm compliance requirements against the material categorization definitions provided in the official documentation.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is required within a ±2% margin. The DO-35 package is suitable for through-hole mounting applications requiring reliable thermal dissipation up to 500 mW. Consider the 33 V breakdown voltage and low leakage current specifications for sensitive reference circuit designs.

Single Zener Diodes Part Context

Single Zener Diodes FAQ

What does the 'C' suffix indicate in the 1N5257C model?

The 'C' suffix specifies a Zener voltage tolerance of ±2%, which is tighter than the standard ±5% tolerance found in the 'B' suffix variants.

What is the maximum power dissipation rating?

The maximum power dissipation is 500 mW at an ambient temperature of 25 °C.
