1N5249C-TAP

Single Zener Diodes Overview

The Vishay General Semiconductor - Diodes Division 1N5249C-TAP is a silicon planar power Zener diode housed in the DO-35 (DO-204AH) axial leaded package. It provides a nominal Zener voltage of 19 V with a tight tolerance of ±2%, indicated by the 'C' suffix. The device operates at a test current of 6.6 mA and features a maximum reverse leakage current of 0.1 µA at 14 V. It supports a total power dissipation of 500 mW, a junction temperature range up to 175 °C, and a storage temperature range from -65 °C to +175 °C.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for robust voltage regulation
• Offers high precision with a ±2% Zener voltage tolerance
• Designed for low leakage current operation
• Capable of handling a 500 mW power dissipation rating

Single Zener Diodes Applications

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the TAP suffix to confirm the specific ammopack tape configuration. Ensure the C suffix is present to guarantee the required ±2% tolerance level. Cross-reference the document number 85588 for the most recent electrical specifications and thermal characteristics before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a precise 19 V reference is required in an axial leaded form factor. The ±2% tolerance makes it suitable for applications demanding tighter voltage accuracy than standard ±5% variants. Consider the 500 mW power rating and thermal resistance limits during circuit design to ensure safe operating conditions under continuous load.

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 Zener voltage range from 2.4 V to 75 V. The 1N5249 variant specifically targets the 19 V segment within this extensive lineup of standard planar power diodes.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 19 V Zener diodes in the DO-35 package with ±2% tolerance. Verify compatibility regarding dynamic impedance and thermal resistance when substituting.
