1N6820R

Overview

The Microchip Technology 1N6820R is a Schottky rectifier diode designed for high-efficiency power conversion. It features a maximum DC reverse voltage (Vr) of 100 V and an average rectified current (Io) of 75 A. The device utilizes Silicon technology and is housed in the ThinKey4 package, which offers very low thermal resistance and low package inductance. This component is available as a reverse polarity, strap-to-cathode configuration, making it suitable for applications requiring robust performance and minimal forward voltage drop.

Feature Summary

• Schottky barrier technology for low forward voltage drop
• ThinKey4 package with very low thermal resistance
• Low package inductance design
• Reverse polarity strap-to-cathode configuration

Applications

• High-current DC-DC converters
• Power supply freewheeling applications
• Solar panel bypass diodes
• Industrial power management systems

Procurement Notes

Verify the specific suffix 'R' indicates the reverse polarity strap-to-cathode variant when sourcing. Confirm the manufacturer is Microchip Technology or its predecessor entities like Microsemi to ensure authenticity. Check RoHS compliance status if required by your assembly specifications. Ensure the packaging type matches your automated handling needs, as bulk packaging is common for this series.

Selection Notes

Select the 1N6820R when a 100 V reverse voltage rating and 75 A continuous current capacity are required. The ThinKey4 package is ideal for designs needing efficient heat dissipation and low parasitic inductance. Consider the reverse polarity configuration if the circuit layout benefits from a strap-to-cathode connection. Compare against standard axial packages if space constraints allow for alternative form factors.

Part Context

This component belongs to the Microchip Technology discrete semiconductor product line, specifically within the Schottky Diodes & Rectifiers category. It is part of a broader family of low-loss rectifiers designed for modern power electronics. The 1N6820R variant specifically addresses the need for high-current handling in compact footprints, leveraging advanced packaging technologies to minimize losses and thermal stress in demanding environments.

Replacement Considerations

Direct substitutes may include other 1N68xx series Schottky diodes from Microchip/Microsemi with matching 100 V and 75 A ratings. Verify pinout compatibility, especially regarding the reverse polarity strap configuration. Alternative manufacturers offering similar ThinKey4 packages should be evaluated for thermal and electrical equivalence before substitution.
