Overview
The SB02W03C-TB-E is a Schottky barrier diode array manufactured by onsemi. It features a dual common cathode configuration housed in an SOT-23 package. The device is rated for a maximum repetitive peak reverse voltage of 30V and provides an average forward rectified current of 200mA. This component is designed for low leakage current applications requiring efficient rectification in compact surface-mount designs.
Feature Summary
- Dual common cathode configuration for space-efficient circuit design
- Schottky barrier technology enabling fast switching performance
- Low reverse leakage current characteristics for improved efficiency
Applications
- DC-DC converter output rectification
- Power supply freewheeling diodes
- Protection circuits against reverse polarity
Procurement Notes
Verify the manufacturer life cycle status, as some sources indicate this part may be obsolete. Confirm package type and pinout compatibility with existing PCB footprints. Ensure the 30V rating meets system voltage requirements. Check for available replacement components if production continuity is required.
Selection Notes
Select this component when a small footprint is critical due to the SOT-23 packaging. Choose based on the 30V reverse voltage limit and 200mA current capacity. Consider the low leakage特性 for sensitive analog or power management sections where minimal standby current is necessary.
Part Context
This diode array belongs to onsemi's rectifier and diode product line, specifically within the Schottky barrier category. It serves as a passive semiconductor component used primarily for converting AC to DC or protecting circuits from reverse voltage. The dual common cathode structure allows for simplified bridge rectifier implementations in low-power applications.
Replacement Considerations
Rochester Electronics lists this part as obsolete. Verify availability through authorized distributors or consider alternative dual Schottky diodes in SOT-23 packages with matching 30V and 200mA ratings. Cross-reference electrical parameters to ensure functional equivalence.
