1N5247C-TAP

Single Zener Diodes Overview

The 1N5247C-TAP is a silicon planar power Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It operates within the 1N5221 to 1N5267 series and features a nominal Zener voltage of 17 V with a ±2% tolerance, indicated by the 'C' suffix. The device is housed in a DO-35 (DO-204AH) axial through-hole package and supports a maximum power dissipation of 500 mW at 25 °C ambient temperature. Electrical characteristics include a test current of 7.4 mA, a reverse leakage current of 0.1 µA at 13 V, and a dynamic resistance of 19 Ω at the test current.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for robust voltage regulation
• Provides tight ±2% Zener voltage tolerance for precision applications
• Designed for high thermal stability with a junction temperature rating up to 175 °C

Single Zener Diodes Applications

• Voltage stabilization circuits
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify that the ordering code explicitly includes the 'C' suffix to ensure the component meets the required ±2% Zener voltage tolerance specification. Confirm the package type matches the DO-35 (DO-204AH) form factor and validate compliance with RoHS3 standards as defined in the manufacturer's material categorization documentation before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a precise 17 V reference is required with tighter tolerances than standard ±5% variants. Ensure the circuit design accommodates the specific test current of 7.4 mA to maintain accurate voltage regulation. Consider the 500 mW power dissipation limit and the thermal resistance characteristics when designing the heat management strategy for the application environment.

Single Zener Diodes Part Context

This part belongs to the Vishay 1N5221 to 1N5267 series of small signal Zener diodes. The series offers a wide range of nominal voltages from 2.4 V to 75 V. The 'TAP' suffix indicates the component is supplied in an ammopack format, while the 'C' designation specifically denotes the tighter manufacturing tolerance compared to the standard 'B' suffix version.
