CEFA102-G

Single Diodes Overview

The Comchip Technology CEFA102-G is a surface mount efficient fast recovery rectifier designed for high-efficiency applications. 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 RMS voltage of 70 V and handles a peak surge forward current of 30 A. It provides a maximum average forward current of 1.0 A with an instantaneous forward voltage of 0.92 V at rated current. The reverse recovery time is 25 ns, and the maximum DC reverse current is 5.0 μA at 25°C. Thermal resistance from junction to lead is 200°C/W.

Single Diodes Feature Summary

• Designed specifically for surface mount applications to facilitate automated pick-and-place assembly processes.
• Constructed with a plastic package classified as UL flammability rating 94V-0 for safety compliance.
• Incorporates built-in strain relief within the molded JEDEC DO-214AC case structure.

Single Diodes Applications

• High frequency switching power supplies
• DC-DC converter circuits
• Free-wheeling diode implementations

Single Diodes Procurement Notes

Verify component authenticity by cross-referencing the manufacturer marking code against official datasheet specifications. Confirm the package type matches the required JEDEC DO-214AC footprint dimensions. Ensure the ordering suffix corresponds to the specific voltage rating variant required for the circuit design. Check for RoHS compliance documentation if environmental regulations apply to the final assembly.

Single Diodes Selection Notes

Select this component when a surface mount fast recovery rectifier is required for compact designs. The 1.0 A current rating suits low-power conversion stages. The 25 ns recovery time makes it suitable for higher frequency operations compared to standard rectifiers. Verify that the thermal management strategy accounts for the specified junction-to-lead thermal resistance during continuous operation.

Single Diodes Part Context

This part belongs to the CEFA series of SMD efficient fast recovery rectifiers manufactured by Comchip Technology. The series covers reverse voltage ratings from 50 V to 600 V in the DO-214AC package. These devices are positioned as alternatives to through-hole rectifiers where space constraints and automated manufacturing efficiency are primary design drivers.

Single Diodes Replacement Considerations

Direct substitutes include other manufacturers' SMA packaged fast recovery diodes with matching 100 V reverse voltage and 1.0 A forward current ratings. Ensure replacement parts maintain equivalent reverse recovery time and forward voltage characteristics to preserve circuit performance.
