1N5261B-TAP

Single Zener Diodes Overview

The Vishay 1N5261B-TAP is a silicon planar power Zener diode with a nominal voltage of 47 V and a ±5% tolerance. It operates in the DO-35 (DO-204AH) axial through-hole package, dissipating up to 500 mW at thermal equilibrium. The device features a maximum reverse leakage current of 100 nA at 36 V and a dynamic impedance of 105 Ω at a test current of 2.7 mA. It supports junction temperatures up to 175 °C and storage ranges from -65 °C to +175 °C.

Single Zener Diodes Feature Summary

• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the TAP suffix to confirm the specific ammopack packaging format. Ensure the required Zener voltage matches the 47 V specification and that the circuit design accommodates the 500 mW power dissipation limit within the DO-35 package constraints.

Single Zener Diodes Selection Notes

Select this component when a 47 V reference is required in an axial leaded package. The ±5% tolerance suits general-purpose applications where tighter precision is unnecessary. Confirm that the operating environment remains within the specified thermal limits to maintain performance reliability.

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 range of voltages from 2.4 V to 75 V, providing standardized options for various electronic designs requiring reliable voltage clamping or regulation.

Single Zener Diodes Replacement Considerations

Cross-reference other manufacturers' 1N5261B equivalents to ensure pinout compatibility and electrical parameter alignment. Verify that any substitute maintains the same DO-35 package dimensions and thermal characteristics.
