Substitute Part Grouping Explanation

Substitution of the ESH3C M6G is determined by the following critical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 150 V minimum
Current - Average Rectified (Io): 3 A minimum
Mounting Type: Surface Mount
Package / Case: DO-214AB (SMC) or compatible surface mount package
Technology: Standard rectifier diode
Operating Temperature - Junction: -55°C to 175°C minimum range

Secondary Compatibility Factors:

Voltage - Forward (Vf) (Max) @ If: 900 mV @ 3 A or lower
Reverse Recovery Time (trr): 20 ns to 40 ns acceptable range
Current - Reverse Leakage @ Vr: 5 µA to 10 µA @ 150 V acceptable range
RoHS3 Compliance and REACH Unaffected status required

Substitute parts are grouped into two categories:

Category 1: Parametric Equivalents (Full 3A Rating) Parts maintaining the full 3 A average rectified current specification with identical or superior electrical characteristics. These parts are direct functional replacements.

Category 2: Functional Substitutes (Reduced Current Rating) Parts rated for 2 A average rectified current with identical voltage and package specifications. These parts are suitable for applications where the full 3 A capability is not required.

Category 3: Package Variants Parts with identical electrical ratings but different surface mount packages (SMB vs. SMC). These require PCB layout modification.

Engineering Selection Recommendations

Primary Recommendation: Vishay ESH3C Series (Parametric Equivalents)

The Vishay ESH3C-E3/57T, ESH3C-E3/9AT, ESH3C-M3/57T, and ESH3C-M3/9AT parts are parametric equivalents to the ESH3C M6G. These parts maintain the full 3 A average rectified current rating, 150 V reverse voltage specification, and identical DO-214AB (SMC) package. All parts operate across the -55°C to 175°C junction temperature range and comply with RoHS3 and REACH requirements. The primary difference is reverse recovery time (40 ns versus 20 ns), which remains within acceptable fast recovery specifications. ESH3C-E3/57T offers the highest inventory availability (30,400 units) among active equivalents.

Automotive-Grade Alternative: Vishay ESH3CHE3_A Series

The ESH3CHE3_A/H and ESH3CHE3_A/I parts provide identical electrical specifications to the ESH3C-E3 series with automotive-grade qualification (AEC-Q101). These parts are suitable for applications requiring automotive component certification while maintaining full 3 A current capability and DO-214AB (SMC) package compatibility.

Secondary Recommendation: Diodes Incorporated ES3C-13-F

The ES3C-13-F is an active substitute maintaining 150 V reverse voltage and 3 A average rectified current in DO-214AB (SMC) package. This part operates across -55°C to 150°C (5°C lower maximum than the original specification) and exhibits 25 ns reverse recovery time. Reverse leakage current is 10 µA at 150 V, compared to 5 µA for the original part. High inventory availability (10,300 units) supports procurement requirements.

Package Variant: Diodes Incorporated ES3CB-13-F

The ES3CB-13-F provides identical electrical specifications to ES3C-13-F but in DO-214AA (SMB) surface mount package. This part requires PCB layout modification and is suitable only when SMB package footprint is available or preferred.

Reduced Current Alternative: Vishay U3C Series

The U3C-E3/57T and U3C-E3/9AT parts are functional substitutes rated for 2 A average rectified current (versus 3 A). These parts maintain 150 V reverse voltage, DO-214AB (SMC) package, and 20 ns reverse recovery time. Selection of these parts is appropriate only for applications where the full 3 A capability is not required.

Frequently Asked Questions (FAQ)

Q: Can the ESH3C-E3/57T directly replace the ESH3C M6G without circuit modification?

A: Yes. The ESH3C-E3/57T maintains identical voltage rating (150 V), current rating (3 A), forward voltage drop (900 mV @ 3 A), and package (DO-214AB SMC). The reverse recovery time increases from 20 ns to 40 ns, which remains within fast recovery specifications. No circuit modification is required.

Q: What is the difference between ESH3C-E3/57T and ESH3C-M3/57T?

A: Both parts share identical electrical specifications: 150 V reverse voltage, 3 A average rectified current, 900 mV forward voltage drop, and DO-214AB (SMC) package. The primary difference is capacitance specification: ESH3C-E3/57T does not specify capacitance, while ESH3C-M3/57T specifies 70 pF @ 4V, 1MHz. Selection depends on circuit requirements for junction capacitance.

Q: Why does the ES3C-13-F have a lower maximum operating temperature (-55°C to 150°C) compared to the original ESH3C M6G (-55°C to 175°C)?

A: The ES3C-13-F is manufactured by Diodes Incorporated with different thermal design specifications. For applications requiring operation above 150°C, the Vishay ESH3C series (rated to 175°C) is required.

Q: Can the U3C-E3/57T be used in place of the ESH3C M6G?

A: The U3C-E3/57T is a functional substitute only for applications where the average rectified current requirement does not exceed 2 A. The part maintains 150 V reverse voltage and DO-214AB (SMC) package compatibility. For circuits requiring the full 3 A capability, this part is not suitable.

Q: What is the significance of the AEC-Q101 qualification on the ESH3CHE3_A series?

A: AEC-Q101 is an automotive electronics qualification standard. The ESH3CHE3_A/H and ESH3CHE3_A/I parts meet automotive-grade reliability and testing requirements. These parts are suitable for automotive applications where component qualification certification is mandatory.

Q: Is the ES3CB-13-F (SMB package) compatible with the original ESH3C M6G (SMC package) design?

A: The ES3CB-13-F is not a direct replacement without PCB modification. The SMB package (DO-214AA) has different physical dimensions and footprint compared to the SMC package (DO-214AB). PCB layout redesign is required for this substitution.

Q: What is the difference between tape and reel (TR) packaging and bulk packaging?

A: Tape and reel (TR) packaging is the standard format for automated assembly processes, with components wound on continuous tape for pick-and-place equipment. The ESH3C M6G original specification does not indicate packaging format, while all active substitutes are available in tape and reel format, which is standard for surface mount components.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (Vishay ESH3C series, Diodes Incorporated ES3C series, and Vishay U3C series) are RoHS3 compliant and REACH unaffected, matching the compliance status of the original ESH3C M6G.

Q: Which substitute part has the highest inventory availability?

A: The Vishay ESH3C-E3/57T has the highest inventory availability at 30,400 units in stock, followed by Diodes Incorporated ES3CB-13-F at 10,400 units and ES3C-13-F at 10,300 units.
