Electrical Parameters:

Voltage - DC Reverse (Vr) (Max): 200 V
Current - Average Rectified (Io): 3 A
Reverse Recovery Time (trr): 30 ns (fast recovery classification)
Operating Temperature - Junction: -55°C to 150°C

Mechanical Parameters:

Package / Case: DO-214AB (SMC)
Mounting Type: Surface Mount

Compliance & Certification:

RoHS Status: ROHS3 Compliant

Substitute parts are grouped into two categories:

Direct Manufacturer Equivalents (Vishay ES3D Series): Parts with identical electrical specifications and automotive-grade AEC-Q101 qualification, differing only in packaging format (Tape & Reel vs. Cut Tape & Digi-Reel).

Parametric Equivalents (Vishay ES3D Variants): Parts meeting all critical electrical and mechanical parameters with active product status, available in multiple packaging configurations.

Cross-Manufacturer Equivalent (Comchip CSFC303-G): A non-Vishay alternative meeting the same voltage, current, and package specifications with minor variations in forward voltage and reverse recovery time within acceptable engineering tolerances.

Engineering Selection Recommendations

For Automotive Applications with AEC-Q101 Requirement:

Select from the following active Vishay parts that maintain automotive-grade qualification and AEC-Q101 certification:

ES3DHE3_A/I (Direct equivalent, Tape & Reel packaging, 55,100 pcs inventory)
ES3DHE3_A/H (Tape & Reel packaging, 1,665 pcs inventory)
ES3DHE3J_A/I (Tape & Reel packaging, 1,014 pcs inventory)
ES3DHM3_A/H (Tape & Reel packaging, 913 pcs inventory)
ES3DHM3_A/I (Tape & Reel packaging, 827 pcs inventory)

For General-Purpose Applications without Automotive Certification Requirement:

The following active Vishay parts provide parametric equivalence with identical electrical specifications:

ES3D-E3/57T (Cut Tape & Digi-Reel packaging, 79,415 pcs inventory)
ES3D-E3/9AT (Cut Tape & Digi-Reel packaging, 110,400 pcs inventory)
ES3D-M3/57T (Tape & Reel packaging, 2,000 pcs inventory)

For Cross-Manufacturer Substitution:

The Comchip CSFC303-G provides parametric equivalence with 200 V reverse voltage and 3 A current rating in DO-214AB package. Forward voltage is specified at 950 mV (50 mV higher than ES3DHE3/9AT) and reverse recovery time is 35 ns (5 ns longer). These differences remain within acceptable engineering tolerances for general rectification applications. This option is available with 729 pcs inventory.

Packaging Considerations:

Tape & Reel (TR) packaging is suitable for high-volume automated assembly
Cut Tape & Digi-Reel packaging provides flexibility for lower-volume or mixed-component orders

Frequently Asked Questions (FAQ)

Q: Can ES3DHE3_A/I directly replace ES3DHE3/9AT in automotive applications?

A: Yes. ES3DHE3_A/I is a direct manufacturer equivalent with identical electrical specifications (200 V, 3 A, 30 ns recovery time), automotive-grade qualification, and AEC-Q101 certification. The only difference is packaging format (Tape & Reel vs. the original format). It is suitable for direct substitution in automotive designs.

Q: What is the difference between ES3D-E3/9AT and ES3DHE3_A/I?

A: Both parts have identical electrical specifications and DO-214AB packaging. ES3DHE3_A/I carries automotive-grade qualification and AEC-Q101 certification, while ES3D-E3/9AT does not specify these certifications. For automotive applications, ES3DHE3_A/I is the appropriate choice. For non-automotive applications, ES3D-E3/9AT is functionally equivalent.

Q: Is CSFC303-G a suitable substitute for ES3DHE3/9AT?

A: CSFC303-G meets the core electrical requirements (200 V, 3 A, DO-214AB package) and is RoHS3 compliant. However, it differs in forward voltage (950 mV vs. 900 mV) and reverse recovery time (35 ns vs. 30 ns). For applications where these parameters are critical, Vishay equivalents are preferred. For general rectification applications with less stringent specifications, CSFC303-G is acceptable.

Q: Why are there multiple Vishay part numbers with the same electrical specifications?

A: The variations in part numbers (ES3DHE3, ES3D-E3, ES3D-M3, ES3DHM3) reflect different manufacturing processes, internal design revisions, or qualification levels. All listed active parts meet the 200 V, 3 A, 30 ns specifications. Selection should be based on automotive certification requirements and packaging format availability.

Q: What does the suffix in part numbers like _A/I and _A/H indicate?

A: The suffix designates the packaging format and tape configuration. _A/I and _A/H both indicate Tape & Reel packaging but may represent different tape specifications or manufacturing batches. Both are functionally equivalent for component selection purposes.

Q: Can I use ES3D-E3/57T instead of ES3D-E3/9AT?

A: Yes. Both parts have identical electrical specifications and DO-214AB packaging. The difference is in the tape format (57T vs. 9AT). Selection depends on your assembly equipment compatibility and tape reel specifications. ES3D-E3/57T has higher inventory availability (79,415 pcs vs. 110,400 pcs for ES3D-E3/9AT).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts, including the Comchip CSFC303-G, are RoHS3 compliant and have MSL 1 (Unlimited) moisture sensitivity classification, matching the original ES3DHE3/9AT specifications.

Q: Which substitute part has the best inventory availability?

A: ES3D-E3/9AT has the highest inventory with 110,400 pcs in stock. ES3D-E3/57T follows with 79,415 pcs. Both are active products with Cut Tape & Digi-Reel packaging and identical electrical specifications to the obsolete ES3DHE3/9AT.
