1N5248C-TAP

Single Zener Diodes Overview

The Vishay 1N5248C-TAP is a silicon planar power Zener diode in the DO-35 (DO-204AH) axial package. It provides an 18 V nominal Zener voltage with a tight ±2 % tolerance, as indicated by the 'C' suffix. The device dissipates up to 500 mW at thermal equilibrium and operates within a junction temperature range of -65 °C to +175 °C. Electrical characteristics include a maximum reverse leakage current of 0.1 µA at 14 V, a typical dynamic resistance of 21 Ω at 7 mA, and a forward voltage of 1.1 V at 200 mA.

Single Zener Diodes Feature Summary

• High precision voltage regulation achieved through a ±2 % Zener voltage tolerance standard for the C-series designation.
• Robust thermal management capabilities allowing operation up to a 175 °C junction temperature limit.
• Low leakage current performance ensuring minimal power loss during reverse bias conditions.

Single Zener Diodes Applications

• Voltage stabilization circuits
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify that the specific ordering code matches the required tolerance level, as the 'C' suffix denotes ±2 % accuracy compared to the standard ±5 % 'B' series. Confirm the TAP packaging format aligns with automated assembly requirements. Ensure compliance with RoHS directives and material categorization standards before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is critical, necessitating the tighter ±2 % tolerance offered by the C-series variant. Evaluate the 500 mW power dissipation capability against the expected operating load to ensure adequate thermal headroom. Consider the DO-35 axial package dimensions for compatibility with existing printed circuit board layouts and mounting constraints.

Single Zener Diodes Part Context

This part belongs to the 1N5221 to 1N5267 family of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide Zener voltage range from 2.4 V to 75 V, providing standardized options for various electronic design applications. The 1N5248 specifically targets the 18 V segment of this extensive portfolio.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering equivalent 18 V, 500 mW Zener diodes in the DO-35 package. Verify that alternative parts meet the same ±2 % tolerance requirement and thermal characteristics to ensure functional equivalence without redesigning the host circuit.
