1N6675

Overview

The Microchip Technology 1N6675 is a Schottky barrier rectifier rated for a peak reverse voltage of 20 volts. It features a maximum forward voltage of 0.37 volts at 20 mA and 0.50 volts at 200 mA. The device has a maximum reverse leakage current of 5.0 µA at +25°C, increasing to 0.6 mA at +100°C. Junction capacitance is limited to 50 pF at 1.0 MHz. It operates within an ambient temperature range of -65°C to +125°C and utilizes a hermetically sealed DO-35 axial-leaded package.

Feature Summary

• Hermetically sealed construction with metallurgically bonded double plug design
• Low forward voltage drop characteristic typical of Schottky barrier technology
• Axial-leaded hard glass DO-35 package suitable for any mounting position

Applications

• High-frequency signal detection circuits
• Power supply rectification in aerospace systems
• Clamping and protection diodes in sensitive electronic interfaces

Procurement Notes

Verify the specific revision level and qualification grade required for your application before ordering. Confirm that the DO-35 package dimensions match your PCB footprint constraints. Ensure thermal management strategies account for the specified derating curves above +100°C. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component when a low forward voltage drop and fast switching speed are critical for circuit efficiency. The 20-volt rating suits low-voltage DC power paths. Consider the hermetic seal requirement for harsh environments where moisture ingress must be prevented. Evaluate the thermal resistance specifications against your expected junction temperatures during continuous operation.

Part Context

This part belongs to the 1N6675 through 1N6677 series of Schottky barrier rectifiers manufactured by Microchip Technology. These devices are designed for applications requiring reliable performance in demanding conditions. The series includes variants with different reverse voltage ratings while maintaining similar electrical characteristics and physical packaging standards.

Replacement Considerations

Direct substitutes include the DSB0.2A20 commercial variant which shares identical electrical parameters and package type. Verify pinout compatibility and thermal characteristics when considering alternative manufacturers' equivalents.
