Engineering Selection Recommendations

ES3DC (MDD): This part is a parametric equivalent to the ES3DC-HF. Both parts share identical electrical specifications including reverse voltage, average rectified current, forward voltage, reverse recovery time, and reverse leakage current. Both are ROHS3 compliant and Active status. The ES3DC is suitable for direct substitution in applications where the Comchip ES3DC-HF is specified.

UF3D_R1_00001 (Panjit International Inc.): This part meets the core electrical requirements of 200 V reverse voltage and 3 A average rectified current with identical forward voltage and operating temperature range. The reverse recovery time is 50 ns (compared to 35 ns for the main part) and reverse leakage current is 1 µA (lower than the 5 µA specification). Both are ROHS3 compliant and Active status. The UF3D_R1_00001 is functionally compatible for general-purpose rectification applications within the specified electrical parameters.

All substitute parts are surface mount devices in DO-214AB (SMC) package format and support the same mounting and assembly processes as the ES3DC-HF.

Frequently Asked Questions (FAQ)

Q: Can ES3DC (MDD) be used as a direct replacement for ES3DC-HF (Comchip)?

A: Yes. The ES3DC shares identical electrical specifications including 200 V reverse voltage, 3 A average rectified current, 1 V forward voltage at 3 A, 35 ns reverse recovery time, and 5 µA reverse leakage current. Both parts are ROHS3 compliant, Active status, and packaged in DO-214AB (SMC) surface mount format.

Q: What are the differences between UF3D_R1_00001 and ES3DC-HF?

A: The UF3D_R1_00001 has a reverse recovery time of 50 ns compared to 35 ns for the ES3DC-HF, and a reverse leakage current of 1 µA compared to 5 µA. Both parts meet the 200 V / 3 A electrical requirements and operate across the same temperature range (-55°C to 150°C). The UF3D_R1_00001 exhibits lower leakage current, which may be beneficial in low-power applications.

Q: Are all substitute parts in the same package?

A: Yes. All listed parts use the DO-214AB (SMC) surface mount package. They are mechanically and electrically compatible for PCB assembly without modification to footprints or mounting procedures.

Q: What compliance certifications apply to these parts?

A: All parts listed are ROHS3 compliant. The ES3DC-HF and UF3D_R1_00001 carry Moisture Sensitivity Level (MSL) 1 (Unlimited). All parts are classified as Active product status.

Q: Can these parts be used interchangeably in high-frequency switching applications?

A: All parts are classified as Fast Recovery diodes with recovery times within acceptable ranges for general-purpose rectification. The ES3DC-HF and ES3DC both specify 35 ns reverse recovery time. The UF3D_R1_00001 specifies 50 ns. Application suitability depends on specific circuit switching frequency requirements.

Q: What inventory levels are available for each part?

A: ES3DC-HF (Comchip): 655 Pcs. ES3DC (MDD): 52,041 Pcs. UF3D_R1_00001 (Panjit): 2,238 Pcs.
