1N5240B-T

Single Zener Diodes Overview

The 1N5240B-T is a silicon planar power Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It provides a nominal Zener voltage of 10 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. Key electrical characteristics include a test current of 20 mA, a reverse leakage current of 3 µA maximum at 9 V, and a dynamic resistance of 17 Ω typical at the test current.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for robust voltage regulation

• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify that the ordering code suffix matches the required packaging format, as the datasheet specifies TAP and TR variants. Confirm compliance with RoHS3 standards and ensure the component meets the specific thermal and electrical requirements of the target application before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 10 V reference with ±5% tolerance is required in an axial through-hole package. Ensure the circuit design accommodates the 500 mW power dissipation limit and verify that the operating temperature range aligns with the specified junction temperature limits.

Single Zener Diodes Part Context

This part belongs to the 1N5221 to 1N5267 series of small signal Zener diodes. The series offers a wide selection of voltages from 2.4 V to 75 V in the same DO-35 package family, allowing designers to maintain consistent mechanical footprints across different voltage regulation designs within a single product line.

Single Zener Diodes Replacement Considerations

Direct replacements within the same Vishay series include 1N5240B-TR and 1N5240B-TAP. Cross-manufacturer equivalents such as 1N759A may be considered if pinout and electrical specifications are verified against the original datasheet.
