1N3515A

Single Zener Diodes Overview

The 1N3515A is a Zener diode manufactured by Microchip Technology, designed for voltage regulation and protection applications. It features a nominal Zener voltage of 7.5 V with a tolerance of ±5%. The device has a maximum power dissipation of 500 mW and operates within a temperature range of -65°C to 175°C. It utilizes a DO-204AH (DO-35) axial through-hole package. Key electrical characteristics include a maximum dynamic impedance of 4 Ohms and a maximum forward voltage of 1.1 V at 200 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at 7.5 V with high precision tolerance
• Capable of handling up to 500 mW power dissipation in a compact axial package
• Operates reliably across an extended industrial temperature range

Single Zener Diodes Applications

• Voltage regulation circuits
• Overvoltage protection systems
• Reference voltage sources

Single Zener Diodes Procurement Notes

Verify the manufacturer origin, as historical production may involve Microsemi or related entities under the Microchip portfolio. Confirm RoHS compliance status and lead-free availability, as legacy variants may contain lead. Ensure the package matches the required DO-35 form factor for your PCB layout. Cross-reference datasheets from authorized distributors to confirm current manufacturing status and specific lot markings.

Single Zener Diodes Selection Notes

Select this component when a precise 7.5 V reference is required with moderate power handling capabilities. The DO-35 package suits through-hole designs where space allows. Consider the ±5% tolerance if tighter regulation is not critical. Evaluate the thermal environment to ensure operation remains within the specified -65°C to 175°C range without exceeding the 500 mW power limit.

Single Zener Diodes Part Context

This part belongs to the standard Zener diode family used for basic voltage clamping and regulation. It is a legacy component often found in established electronic designs requiring reliable, low-cost voltage references. The DO-35 package is a common axial leaded format suitable for general-purpose electronics.

Single Zener Diodes Replacement Considerations

Check for direct equivalents such as other 7.5V 500mW Zener diodes in DO-35 packages from different manufacturers. Verify pinout compatibility and electrical parameter overlaps before substitution.
