1N5245B-TAP

Single Zener Diodes Overview

The 1N5245B-TAP is a silicon planar power Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It provides a nominal Zener voltage of 15 V with a standard tolerance of ±5%. The device operates in the DO-35 (DO-204AH) axial leaded package and supports a maximum power dissipation of 500 mW at thermal equilibrium. Electrical characteristics include a test current of 8.5 mA, a maximum reverse leakage current of 0.1 µA, and a typical dynamic resistance of 16 Ω. The component functions as a single circuit configuration with a junction temperature rating up to 175 °C.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for robust voltage regulation

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the TAP suffix to confirm the specific ammo pack packaging format. Ensure the required Zener voltage tolerance aligns with the standard ±5% specification associated with the B suffix. Confirm that the DO-35 package dimensions match the target PCB layout constraints before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 15 V reference point is required within a 500 mW power budget. The DO-35 package is suitable for through-hole mounting applications where axial leads are preferred. Consider the 16 Ω dynamic resistance value for applications requiring moderate impedance stability under varying load currents.

Single Zener Diodes Part Context

This part belongs to the 1N5221 to 1N5267 series of small signal Zener diodes from Vishay Semiconductors. The series covers a wide range of nominal voltages from 2.4 V to 75 V. The 1N5245B variant specifically targets the mid-range voltage segment, offering a balance between low leakage and manageable dynamic resistance for general-purpose regulation tasks.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5245 equivalents. Verify that substitute parts maintain the same DO-35 footprint and 500 mW power rating. Ensure the replacement's Zener voltage tolerance meets the ±5% requirement if strict voltage accuracy is necessary.
