Procurement Notes

Verify component authenticity by checking the marking code against official Toshiba Semiconductor documentation. Ensure compliance with environmental directives such as RoHS before integration. Review the Toshiba Semiconductor Reliability Handbook for derating guidelines and thermal management requirements to maintain operational safety under varying load conditions.

Selection Notes

Select this component when designing circuits requiring fast recovery characteristics and low conduction losses. Evaluate thermal performance carefully due to the inherent reverse leakage properties of Schottky barriers. Confirm that the operating voltage and current limits remain within the specified absolute maximum ratings to prevent reliability degradation.

Part Context

This device belongs to the Toshiba Schottky Barrier Diode family, utilizing silicon epitaxial technology. It is engineered to provide efficient rectification in compact form factors. The CST2C package allows for dense board assembly while maintaining electrical isolation between the cathode and anode terminals.

Replacement Considerations

Consult official Toshiba documentation for verified substitute part numbers. Do not assume functional equivalence with generic Schottky diodes without verifying pinout compatibility and electrical parameter alignment.
