Overview
The CDBA240L-G is a surface mount Schottky barrier rectifier manufactured by Comchip Technology. It features a DO-214AC (SMA) molded plastic package with solderable terminals and built-in strain relief. The device supports a maximum repetitive peak reverse voltage of 40 V and a maximum DC blocking voltage of 40 V. It handles a maximum average forward current of 2.0 A and a peak surge forward current of 50 A. Key electrical characteristics include a maximum instantaneous forward voltage of 0.40 V at 2.0 A and a maximum DC reverse current of 2 mA at rated voltage. Thermal resistance is 75 °C/W, with an operating junction temperature range up to 125 °C.
Feature Summary
- Super low forward voltage drop for improved efficiency
- Plastic package with Underwriters Lab flammability classification 94V-0
- Built-in strain relief for mechanical stability
- Easy pick and place suitability for surface mount applications
Applications
- Surface mount power supply circuits
- DC-DC converter input/output stages
- Free-wheeling diode applications in inductive loads
Procurement Notes
Verify the specific part number against the official Comchip Technology datasheet to confirm the 40V reverse voltage rating and 2.0A forward current specifications. Ensure the DO-214AC package dimensions match the target PCB footprint. Confirm RoHS compliance status as indicated in the product documentation before finalizing procurement orders.
Selection Notes
Select this component for designs requiring low forward voltage drop in surface mount configurations. The 40V reverse voltage rating suits low-voltage DC systems. Verify thermal management requirements, as the 75 °C/W thermal resistance necessitates adequate copper pad areas for heat dissipation during high-current operation.
Part Context
This component belongs to the CDBA220L-G through CDBA240LL-G series of Low VF SMD Schottky Barrier Rectifiers from Comchip Technology. The series shares identical physical packaging and general electrical characteristics, differing primarily in their maximum repetitive peak reverse voltage ratings ranging from 20V to 40V.
Replacement Considerations
Compatible substitutes within the same series include CDBA220L-G and CDBA240LL-G, provided the reverse voltage requirements align with the circuit design. Cross-manufacturer replacements must match the DO-214AC package, 2.0A current rating, and 0.40V forward voltage specifications.
