Substitute Part Grouping Explanation

Substitute parts for the ES3DB-HF are grouped based on strict parametric equivalence within the following criteria:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 200 V
Current - Average Rectified (Io): 3 A
Voltage - Forward (Vf) (Max) @ If: 1 V @ 3 A
Package / Case: DO-214AA, SMB
Mounting Type: Surface Mount
Operating Temperature - Junction: -55°C to 150°C
RoHS Status: ROHS3 Compliant

Secondary Variation Parameters (Allowed Deviations):

Reverse Recovery Time (trr): 35 ns to 50 ns
Current - Reverse Leakage @ Vr: 5 µA to 100 µA @ 200 V
Capacitance @ Vr, F: 45 pF to 80 pF @ 4V, 1MHz

Engineering Selection Recommendations

ES3DB (MDD): This part is a direct parametric equivalent to ES3DB-HF with identical electrical specifications and Active product status. It is suitable for direct substitution in applications requiring Tape & Reel packaging format.

ES3DB R5G (Taiwan Semiconductor Corporation): This part meets all primary electrical criteria with reverse leakage current of 10 µA at 200 V, within acceptable tolerance. Product status is Discontinued at DiGi Electronics; availability through alternative distribution channels should be confirmed. Packaging format is Cut Tape (CT).

ES3DBHR5G (Taiwan Semiconductor Corporation): This part meets all primary electrical criteria with reverse leakage current of 100 µA at 200 V, within acceptable tolerance. Product status is Active. Packaging format is Cut Tape (CT). This variant exhibits higher reverse leakage than the main part but remains within functional parameters for standard rectification applications.

HS3DB (Taiwan Semiconductor Corporation): This part meets all primary electrical criteria with reverse recovery time of 50 ns (compared to 35 ns for ES3DB-HF) and reverse leakage current of 10 µA at 200 V. Product status is Active. Packaging format is Tape & Reel (TR). The extended reverse recovery time represents a secondary parameter variation within acceptable limits.

HS3DB R5G (Taiwan Semiconductor Corporation): This part meets all primary electrical criteria with reverse recovery time of 50 ns and reverse leakage current of 10 µA at 200 V. Product status is Discontinued at DiGi Electronics. Packaging format is Cut Tape (CT). Availability confirmation is required.

All substitute parts are ROHS3 compliant and operate across the -55°C to 150°C junction temperature range.

Frequently Asked Questions (FAQ)

Q: Can ES3DB-HF be directly replaced with ES3DB?

A: Yes. ES3DB manufactured by MDD is a direct parametric equivalent with identical voltage, current, forward voltage, and reverse recovery time specifications. Both are Active products in Tape & Reel packaging.

Q: What is the difference between ES3DB-HF and HS3DB?

A: The primary difference is reverse recovery time: ES3DB-HF specifies 35 ns while HS3DB specifies 50 ns. Both maintain 200 V reverse voltage and 3 A current ratings. HS3DB exhibits higher junction capacitance (80 pF versus 45 pF at 4V, 1MHz). Both are Active products suitable for general purpose rectification.

Q: Are Cut Tape (CT) and Tape & Reel (TR) packaging interchangeable?

A: Cut Tape and Tape & Reel are different packaging formats for the same DO-214AA/SMB component. Electrical specifications remain identical. Packaging selection depends on assembly equipment and production volume requirements. Both formats are compatible with surface mount assembly processes.

Q: Why do some substitute parts show higher reverse leakage current?

A: Reverse leakage current variations (5 µA to 100 µA at 200 V) reflect manufacturing tolerance ranges within the fast recovery rectifier diode category. All values remain within acceptable limits for standard rectification applications and do not affect functional performance in typical circuit designs.

Q: Can I use ES3DBHR5G as a substitute if ES3DB-HF is unavailable?

A: Yes. ES3DBHR5G meets all primary electrical specifications with 200 V reverse voltage, 3 A current rating, and 1 V forward voltage at 3 A. The reverse leakage current of 100 µA at 200 V is within acceptable tolerance. Product status is Active.

Q: What does "Discontinued at DiGi Electronics" mean for ES3DB R5G and HS3DB R5G?

A: This designation indicates the part is no longer actively stocked or distributed through DiGi Electronics. Availability through alternative distribution channels or direct manufacturer sources should be verified before design selection.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant certification, matching the compliance status of ES3DB-HF.

Q: Which substitute part has the lowest reverse leakage current?

A: ES3DB and ES3DB-HF both specify 5 µA reverse leakage current at 200 V, representing the lowest value in the substitute group.
