ES3DB Equivalent & Substitute Parts

Part Overview

The ES3DB is a general-purpose fast recovery rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 200 V DC reverse voltage and 3 A average rectified current in a surface mount DO-214AA (SMB) package. The device is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity level. Alternative equivalent and substitute parts are necessary to address packaging format preferences, inventory availability, manufacturer sourcing requirements, and application-specific performance variations while maintaining electrical compatibility within the 200 V / 3 A operating envelope.

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents maintain identical or functionally equivalent electrical specifications across all critical parameters: 200 V reverse voltage, 3 A average rectified current, 1 V forward voltage drop at 3 A, fast recovery characteristics (≤500 ns), and DO-214AA SMB package form factor. These parts differ only in packaging format (Tape & Reel versus Cut Tape) or minor variations in reverse leakage current and capacitance that remain within acceptable operating margins.

Similar Parts share the same 200 V reverse voltage rating and DO-214AA SMB package but operate at reduced current ratings (1 A or 2 A) or are manufactured by alternative suppliers. These parts are suitable for applications where the full 3 A current capacity is not required, or where alternative manufacturer sourcing is acceptable.

The following key parameters determine substitution eligibility:

Voltage - DC Reverse (Vr) (Max): Must equal 200 V
Package / Case: Must be DO-214AA, SMB
Mounting Type: Must be Surface Mount
Technology: Must be Standard fast recovery rectifier

Engineering Selection Recommendations

Parametric Equivalent Selection (Preferred for Direct Substitution)

ES3DB R5G and ES3DBHR5G are parametric equivalents of ES3DB manufactured by Taiwan Semiconductor Corporation. Both maintain 200 V reverse voltage, 3 A current rating, and DO-214AA SMB package compatibility. ES3DB R5G is electrically identical to the main part but supplied in Cut Tape format; however, this part is discontinued at DiGi Electronics and should not be selected for new designs. ES3DBHR5G is Active status and available in Cut Tape format with identical electrical performance except for elevated reverse leakage current (100 µA versus 10 µA at 200 V), which remains within acceptable operating margins for general-purpose rectification applications.

HS3DB and HS3DB R5G are parametric equivalents from Taiwan Semiconductor Corporation with identical voltage and current ratings in DO-214AA SMB package. These parts exhibit longer reverse recovery time (50 ns versus 35 ns) and higher capacitance (80 pF versus 46 pF at 4 V, 1 MHz). HS3DB is Active status in Tape & Reel format. HS3DB R5G is discontinued at DiGi Electronics and should not be selected for new designs.

Alternative Manufacturer Selection (3 A Rating)

ER3DB-TP manufactured by Micro Commercial Co is a 200 V / 3 A fast recovery rectifier in DO-214AA SMB package with Active product status. This part exhibits lower forward voltage drop (950 mV versus 1 V at 3 A) and lower reverse leakage current (5 µA versus 10 µA at 200 V), making it suitable for applications requiring reduced power dissipation. Reverse recovery time matches the main part at 35 ns.

Reduced Current Rating Selection (2 A)

ER2D-LTP (Micro Commercial Co), ES2D-13-F (Diodes Incorporated), and ES2DHE3_A/H (Vishay) are 200 V / 2 A fast recovery rectifiers in DO-214AA SMB package. These parts are suitable for applications where 3 A capacity is not required. ES2DHE3_A/H includes AEC-Q101 automotive qualification. All three maintain Active product status and ROHS3 compliance.

Reduced Current Rating Selection (1 A)

ER1D-LTP manufactured by Micro Commercial Co is a 200 V / 1 A fast recovery rectifier in DO-214AA SMB package with Active product status. This part is suitable for low-current applications and exhibits lower reverse leakage current (5 µA at 200 V).

Package Format Consideration

ES2DA-13-F (Diodes Incorporated) is a 200 V / 2 A fast recovery rectifier supplied in DO-214AC SMA package rather than SMB. This part is not suitable for direct substitution if SMB package footprint is required.

Frequently Asked Questions (FAQ)

Q: Can ES3DB R5G be used as a direct replacement for ES3DB?

A: ES3DB R5G is electrically identical to ES3DB with matching 200 V reverse voltage, 3 A current rating, 1 V forward voltage drop, and 35 ns reverse recovery time. However, ES3DB R5G is discontinued at DiGi Electronics and should not be selected for new designs. For new applications, use ES3DBHR5G or HS3DB, both of which are Active status.

Q: What is the difference between ES3DBHR5G and HS3DB?

A: Both parts are 200 V / 3 A fast recovery rectifiers in DO-214AA SMB package manufactured by Taiwan Semiconductor Corporation with Active product status. ES3DBHR5G is supplied in Cut Tape format with 35 ns reverse recovery time and 100 µA reverse leakage current at 200 V. HS3DB is supplied in Tape & Reel format with 50 ns reverse recovery time and 10 µA reverse leakage current at 200 V. Selection depends on packaging format preference and acceptable reverse recovery time variation.

Q: Can ER3DB-TP replace ES3DB in all applications?

A: ER3DB-TP is a parametric equivalent with identical 200 V reverse voltage and 3 A current rating in DO-214AA SMB package. ER3DB-TP exhibits lower forward voltage drop (950 mV versus 1 V at 3 A) and lower reverse leakage current (5 µA versus 10 µA at 200 V), making it suitable for direct substitution. Both parts maintain 35 ns reverse recovery time and are ROHS3 compliant.

Q: When should I use 2 A or 1 A rated parts instead of 3 A?

A: Use reduced current rating parts (ER2D-LTP, ES2D-13-F, ES2DHE3_A/H for 2 A; ER1D-LTP for 1 A) only when circuit design confirms that maximum current demand does not exceed the part's rating. These parts maintain 200 V reverse voltage rating and DO-214AA SMB package compatibility. Reduced current parts may offer lower forward voltage drop and reverse leakage current, benefiting power efficiency in low-current applications.

Q: Is ES2DA-13-F compatible with ES3DB?

A: ES2DA-13-F is not suitable for direct substitution. While it maintains 200 V reverse voltage and 2 A current rating, it is supplied in DO-214AC SMA package rather than DO-214AA SMB package. SMA and SMB packages have different physical dimensions and PCB footprints and are not interchangeable.

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

A: Parts marked as "Discontinued at DiGi Electronics" are no longer actively stocked or supported through this distribution channel. For new designs, select parts with Active product status: ES3DBHR5G, HS3DB, ER3DB-TP, or other Active alternatives listed in this reference.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed in this reference maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), meeting environmental and regulatory requirements for commercial and industrial applications.

Q: What is the significance of reverse recovery time (trr) differences?

A: Reverse recovery time affects switching speed and electromagnetic interference characteristics. ES3DB and ER3DB-TP specify 35 ns trr, while HS3DB and HS3DB R5G specify 50 ns trr. Lower trr values (25 ns for ES2D-13-F and ES2DHE3_A/H) indicate faster switching performance. Selection depends on circuit switching frequency and EMI requirements.
