Overview
The RB228T-40NZC9 is a Schottky barrier diode manufactured by Rohm Semiconductor, designed for high-reliability applications. It features a cathode common dual configuration housed in a TO-220FN (3PIN) leaded package. The device supports an average rectified forward current of 30A and withstands a reverse voltage of 40V with a maximum repetitive peak reverse voltage of 45V. Key electrical characteristics include a maximum forward voltage of 0.77V at 15A and a maximum reverse current of 0.01mA at 40V. It operates within a junction temperature range up to 150°C and is RoHS compliant.
Feature Summary
- Cathode common dual type configuration
- Super low reverse leakage current (IR)
- High reliability construction
Applications
- General purpose rectification in power supplies
- Freewheeling diodes in DC-DC converters
- Protection circuits in industrial equipment
Procurement Notes
Verify the specific suffix C9 corresponds to the tube packaging format containing 1000 units per tube as documented. Confirm that this component is designated as 'Not Recommended for New Designs' for any new development projects, indicating it is maintained primarily for supporting existing legacy systems rather than being promoted for future adoption.
Selection Notes
Select this component when a through-hole TO-220FN package is required for high-current applications needing 30A continuous rating. Ensure the circuit design accommodates the 40V reverse voltage limit and utilizes the dual cathode common topology for efficient space-constrained layouts. Verify thermal management capabilities are sufficient to maintain junction temperatures below the 150°C maximum limit under expected load conditions.
Part Context
This part belongs to the RB228T series of Schottky barrier diodes from Rohm Semiconductor. The series is characterized by low reverse leakage current and high reliability, making it suitable for various electronic devices. The RB228T-40NZC9 specifically denotes the 40V variant in the leaded TO-220FN package format.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. As this component is marked 'Not Recommended for New Designs,' alternative selection should involve consulting official Rohm databases for current recommended equivalents that meet similar electrical and mechanical specifications.
