1N5248B-TAP

Single Zener Diodes Overview

The Vishay General Semiconductor - Diodes Division 1N5248B-TAP is a silicon planar power Zener diode with a nominal voltage of 18 V and ±5% tolerance. It operates in the DO-204AH (DO-35) axial through-hole package, dissipating up to 500 mW at thermal equilibrium. The device features a maximum dynamic impedance of 21 Ohms at a test current of 7 mA, with a reverse leakage current of 100 nA at 14 V. It supports junction temperatures up to 175 °C and withstands peak soldering temperatures of 260 °C.

Single Zener Diodes Feature Summary

Single Zener Diodes Procurement Notes

Verify the specific ordering code suffix against official documentation to confirm packaging format and tolerance class. Ensure the procurement specification matches the required electrical parameters, particularly the Zener voltage range and dynamic impedance limits defined in the datasheet. Confirm compliance with material categorization standards prior to finalizing orders.

Single Zener Diodes Selection Notes

Select this component when a stable 18 V reference is required in through-hole designs. The DO-35 package accommodates standard PCB mounting techniques. Evaluate the thermal resistance characteristics if operating near the maximum power dissipation limit. Consider the temperature coefficient for applications requiring high precision across varying ambient conditions.

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 'B' suffix indicates the standard ±5% tolerance variant, while other suffixes denote tighter tolerances or different packaging configurations within the same product family.
