1N5247B-TAP

Single Zener Diodes Overview

The 1N5247B-TAP is a silicon planar power Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It provides a nominal Zener voltage of 17 V with a standard tolerance of ±5%. The device operates in the DO-35 (DO-204AH) axial through-hole package and supports a maximum power dissipation of 500 mW at thermal equilibrium. Key electrical parameters include a test current of 7.4 mA, a maximum reverse leakage current of 0.1 µA at 13 V, and a typical dynamic resistance of 19 Ω at the test current.

Single Zener Diodes Feature Summary

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the TAP suffix to confirm the specific ammopack packaging format. Ensure the component meets RoHS3 compliance requirements for your manufacturing process. Cross-reference the exact part number against the manufacturer's latest datasheet revision to confirm availability and any potential design changes before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 17 V reference point is required within a low-power application. The ±5% tolerance suits general-purpose regulation tasks where tight precision is not critical. Consider the DO-35 package dimensions for PCB layout constraints and verify that the 500 mW power rating accommodates the expected operating conditions without exceeding thermal limits.

Single Zener Diodes Part Context

This component belongs to the 1N5221 to 1N5267 series of small signal Zener diodes produced by Vishay Semiconductors. The series covers a wide range of Zener voltages from 2.4 V to 75 V. The 1N5247B variant specifically targets the 17 V segment of this lineup, offering standardized performance characteristics consistent with the broader family specifications.
