CDBA3100-G

Overview

The CDBA3100-G is a surface-mount Schottky barrier rectifier from Comchip Technology, housed in a JEDEC DO-214AC (SMA) molded plastic package. It features a maximum repetitive peak reverse voltage of 100 V and a maximum DC blocking voltage of 100 V. The device supports a maximum average forward current of 3.0 A and can withstand a peak surge forward current of 80 A for an 8.3 ms single half-sine wave. Key electrical characteristics include a maximum instantaneous forward voltage of 0.85 V at 3.0 A and a maximum DC reverse current of 10 mA at rated DC blocking voltage and 25°C ambient temperature.

Procurement Notes

Verify the specific part number CDBA3100-G against official Comchip Technology datasheets to confirm the 100V reverse voltage rating and 3.0A current capacity. Ensure compatibility with DO-214AC (SMA) footprint requirements on the target PCB layout. Confirm RoHS and Halogen-Free compliance status if required by your manufacturing standards. Cross-reference marking codes '3100' and 'C' for accurate identification upon receipt.

Selection Notes

Select this component when a 100V reverse voltage rating and 3.0A continuous forward current are required in a compact SMA package. Consider its low forward voltage characteristic for efficiency-sensitive designs. Verify that the thermal resistance parameters align with the expected junction temperature limits under the specific operating conditions of the application circuit.

Part Context

This device belongs to the CDBA series of SMD Schottky Barrier Rectifiers manufactured by Comchip Technology CO., LTD. The series covers reverse voltages from 20V to 100V within the same DO-214AC package form factor. The CDBA3100-G represents the highest voltage variant in this specific lineup, sharing mechanical and thermal characteristics with lower voltage counterparts like the CDBA320-G through CDBA380-G.

Replacement Considerations

Direct substitutes must match the DO-214AC (SMA) package, 100V reverse voltage, and 3.0A forward current ratings. Verify pinout polarity and forward voltage specifications to ensure circuit compatibility. Check manufacturer datasheets for equivalent Schottky rectifiers offering similar thermal and electrical performance metrics.
