1N4693E3

Overview

The 1N4693E3 is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation and reference applications. It features a nominal Zener voltage of 7.5 V with a tolerance of ±5%. The device operates in a DO-35-2 axial leaded package, suitable for through-hole mounting. Key electrical specifications include a maximum power dissipation of 500 mW, a maximum reverse leakage current of 10 µA, and a test current of 50 µA. The component supports an operating temperature range from -65 °C to +175 °C.

Feature Summary

• Provides stable voltage regulation at a nominal 7.5 V reference level
• Capable of handling up to 500 mW of power dissipation
• Engineered for high-temperature operation extending to +175 °C
• Utilizes a standard DO-35-2 axial through-hole package

Applications

• Voltage regulation circuits
• Voltage reference sources
• Overvoltage protection stages

Procurement Notes

Verify the specific suffix configuration when ordering, as the TR suffix indicates tape and reel packaging per EIA-296 standards. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to procurement. Ensure that the required quantity aligns with the available packaging format to avoid partial reel issues. Cross-reference the exact part number against official Microchip documentation to confirm current production status and availability constraints.

Selection Notes

Select this component when a precise 7.5 V Zener reference is required within a through-hole design. The 500 mW power rating allows for moderate current handling in regulation tasks. Consider the wide operating temperature range if the application involves harsh thermal environments. Verify that the DO-35-2 package dimensions fit the target PCB layout and that the ±5% voltage tolerance meets the circuit's precision requirements.

Part Context

This device belongs to the 1N4689 series of Zener diodes produced by Microchip Technology. The series offers various voltage options within the same physical footprint, allowing for design flexibility. The 1N4693E3 specifically targets the 7.5 V segment of this lineup. These components are widely used in discrete semiconductor applications requiring reliable voltage clamping or referencing in industrial and commercial electronics.

Replacement Considerations

Direct substitutes may include other 1N4693 variants from different manufacturers, provided they match the 7.5 V Zener voltage, 500 mW power rating, and DO-35 package style. Verify pinout compatibility and thermal characteristics before substitution. Ensure that any alternative component meets the same ±5% tolerance and temperature range specifications.
