The RB205T-40NZC9 is a silicon Schottky barrier diode designed for automotive applications, complying with the AEC-Q101 standard. It features a common cathode configuration housed in a TO-220FN (3-pin) leaded package. The device supports a maximum repetitive reverse voltage of 40V and an average rectified forward current of 15A. Key electrical characteristics include a maximum forward voltage of 0.55V at 7.5A and a maximum reverse current of 0.3mA at 40V. It operates within a junction temperature range up to 150°C and is RoHS compliant.
This component is designated as 'Not Recommended for New Designs' by the manufacturer. Production is limited to supporting existing customers only. Verify current availability status directly with authorized distributors or the manufacturer before initiating any procurement process, as new design integration is explicitly discouraged.
Engineers should prioritize newer alternative components from the manufacturer's portfolio for any fresh design projects due to the discontinued status for new designs. If this specific part is required for maintenance or legacy system repair, ensure strict adherence to the AEC-Q101 qualification requirements and verify that the TO-220FN package dimensions match the existing board layout constraints.
The RB205T series represents ROHM Semiconductor's line of automotive-grade Schottky barrier diodes. These devices are engineered to meet the rigorous quality and reliability standards required for automotive electronics. The specific model utilizes silicon technology to provide fast switching speeds and low forward voltage drops, making it suitable for efficient power management in vehicle systems.
Public documentation confirms the RB205T-40HZC9 as a verified substitute within the same product family. Both parts share identical electrical specifications and packaging. Users should confirm that the substitution does not impact existing mechanical clearances or thermal management designs.
