1N5240

Single Zener Diodes Overview

The 1N5240 is a single silicon planar power Zener diode manufactured by SMC Diode Solutions. It provides a nominal Zener voltage of 10 V with a standard tolerance of ±20%. The device is rated for a maximum power dissipation of 500 mW at ambient temperature. It utilizes the DO-35 axial through-hole package, which measures approximately 3.6 mm in length and 1.7 mm in diameter. The component supports a junction temperature range from -65°C to +200°C and operates within a storage temperature range of -65°C to +200°C.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for robust performance
• Provides stable voltage regulation at 10 V nominal level
• Designed for high thermal stability with extended junction temperature limits

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in low-power electronics
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as SMC Diode Solutions acquired assets from General Semiconductor and Sensitron. Confirm that the datasheet corresponds to the exact part number 1N5240 without suffix variations like 'B' which alter tolerance. Ensure the package matches the DO-35 specification and check for RoHS compliance status if required by your manufacturing standards.

Single Zener Diodes Selection Notes

Select this component when a 10 V Zener voltage is required in an axial through-hole configuration. The 500 mW power rating suits low-current regulation tasks. Consider the ±20% tolerance if precise voltage accuracy is not critical. For tighter tolerances, verify if a 'B' suffix variant is available and appropriate for the design requirements.

Single Zener Diodes Part Context

The 1N5240 belongs to the standard Zener diode family used for basic voltage regulation. It is commonly found in legacy and industrial designs where axial mounting is preferred. The component represents a fundamental discrete semiconductor solution for maintaining constant voltage levels across varying load conditions in simple electronic circuits.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N4740A (10V, 1W, DO-41) for higher power handling or the MMSZ5240B (10V, 500mW, SOD-123) for surface mount applications. Verify pin compatibility and thermal derating curves when substituting.
