1N3506A

Single Zener Diodes Overview

The Microchip Technology 1N3506A is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 5.1 V with a maximum power dissipation of 500 mW at 25°C ambient temperature. The device utilizes a DO-35 axial-leaded glass package, suitable for through-hole mounting. Key electrical characteristics include a maximum Zener impedance (Zzt) of 7 Ohms and a forward voltage drop of 1.1 V at 200 mA. The component operates within a junction and storage temperature range of -65°C to +175°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a 5.1 V Zener reference in a compact glass axial package.
• Supports high-temperature operation up to 175°C junction temperature for demanding environments.
• Offers low dynamic impedance for effective noise filtering and signal conditioning.

Single Zener Diodes Applications

• Voltage reference circuits requiring precise DC levels
• Overvoltage protection stages in electronic systems
• Clamping applications for transient suppression

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements against the official datasheet before ordering, as tolerance variations may exist. Confirm RoHS compliance status, as standard versions may not meet current environmental directives. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability of the semiconductor components.

Single Zener Diodes Selection Notes

Select this component when a 5.1 V regulation point is required with moderate power handling capabilities. The DO-35 package is appropriate for general-purpose PCB layouts where space is limited but through-hole reliability is preferred. Consider the thermal derating curves if operating above 25°C ambient conditions to ensure the 500 mW limit is not exceeded.

Single Zener Diodes Part Context

The 1N3506A belongs to the 1N3506A through 1N3534A series of 400mW Zener Voltage Regulator Diodes manufactured by Microchip Technology. This series provides a wide selection of voltage values in the standard DO-35 axial-leaded glass package. These devices are commonly used in industrial and commercial electronics where reliable voltage referencing is critical.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N3506A equivalents or parts from the same series with identical voltage ratings. Verify pinout compatibility and package dimensions (DO-35) to ensure mechanical fit. Electrical parameters such as Zener impedance and leakage current should be compared against the original specification sheet.
