Product details

What this SiC Schottky brings to the power stage

Its zero reverse recovery time — no stored charge, no recovery tail — eliminates the switching loss term that dominates in hard-switched PFC, boost, and DC-DC converters. The 175 °C maximum junction temperature gives headroom for under-hood and high-ambient automotive environments where a silicon ultrafast would need aggressive derating or active cooling.

The 0 ns reverse recovery time eliminates the stored-charge recovery spike that a silicon ultrafast diode would produce in a continuous-conduction-mode PFC stage.

Package and mounting — D²Pak (TO-263) on an automotive-grade footprint

The PG-TO263-2 package (D²Pak, 2 leads plus tab) is a standard surface-mount power package. The large tab is the cathode and carries the main thermal path.

Infineon lists it as current-production in the CoolSiC™ Automotive portfolio.

Frequently asked questions

What does 'No Recovery Time > 500mA (Io)' mean in the spec?

It means the diode's reverse recovery time is zero — no stored charge, no recovery tail — at forward currents above 500 mA. This is inherent to the SiC Schottky structure; the diode turns off the instant the voltage reverses, eliminating the switching loss that a silicon ultrafast diode would incur.

What compliance documentation does Infineon provide for this part?

The part is RoHS3 compliant (lead-free, no restricted substances above threshold). Infineon typically provides a RoHS certificate, REACH declaration, and material declaration on request. AEC-Q101 qualification documents are available through the Infineon automotive portal.

What is the closest pin-compatible alternative in the same family?

Within the CoolSiC™ Automotive 650 V family, the higher-current siblings (e.g., 10 A, 12 A) share the same PG-TO263-2 footprint and pinout. For a direct drop-in with the same 8 A rating, Infineon's own portfolio does not list a second-source cross — no pin-compatible alternate from another manufacturer is formally documented. The part is single-sourced to Infineon.
