Substitution of the ES3CHM6G is determined by matching the following critical electrical and mechanical parameters:

Electrical Parameters:

Voltage - DC Reverse (Vr) (Max): 150 V
Current - Average Rectified (Io): 3 A
Reverse Recovery Time (trr): ≤ 500 ns (Fast Recovery classification)
Operating Temperature - Junction: -55°C to 150°C

Mechanical Parameters:

Mounting Type: Surface Mount
Package / Case: DO-214AB (SMC) or compatible SMC/SMB variants

Compliance Parameters:

Substitute parts are classified into two categories:

Parametric Equivalents: Parts that match all critical electrical specifications and package requirements, enabling direct replacement without circuit redesign.

Similar Parts: Components that meet the core voltage and current ratings but may differ in secondary parameters (forward voltage, reverse recovery time, reverse leakage current) or package form factor (SMB vs. SMC), requiring engineering evaluation for specific application contexts.

Engineering Selection Recommendations

Parametric Equivalents for Direct Replacement:

ES3C (Taiwan Semiconductor Corporation): This part is a parametric equivalent offering identical electrical specifications to the ES3CHM6G across all critical parameters. The ES3C is currently active in production with significantly higher inventory availability (10,200 pcs). This part is suitable for direct substitution in applications where the automotive grade and AEC-Q101 qualification of the original part are not mandatory requirements.

ES3CH (Taiwan Semiconductor Corporation): This part maintains full parametric equivalence with the ES3CHM6G and includes automotive-grade classification and AEC-Q101 qualification, matching the original part's compliance profile. The ES3CH is active in production and represents the optimal substitute for automotive and safety-critical applications requiring maintained qualification status.

ER3C_R1_00001 (Panjit International Inc.): This parametric equivalent matches all electrical specifications of the ES3CHM6G with the exception of reverse leakage current (1 µA versus 10 µA at 150 V), which represents an improvement in leakage performance. The part is available in SMC (DO-214AB) package and is currently active in production with 1,139 pcs in stock.

Similar Parts for Application-Specific Evaluation:

ES3C-13-F (Diodes Incorporated): This part meets the core voltage and current ratings but differs in forward voltage (900 mV versus 950 mV at 3 A) and reverse recovery time (25 ns versus 35 ns). These improvements in switching performance may benefit high-frequency applications. The package is DO-214AB (SMC) with Tape & Reel packaging. Automotive qualification is not specified.

ES3CB-13-F (Diodes Incorporated): This part provides equivalent electrical performance to ES3C-13-F but in a DO-214AA (SMB) package form factor. Selection of this variant requires PCB layout compatibility with the SMB package footprint. Automotive qualification is not specified.

Frequently Asked Questions (FAQ)

Q: Can ES3C be used as a direct replacement for ES3CHM6G in automotive applications?

A: ES3C matches all electrical parameters but lacks automotive-grade designation and AEC-Q101 qualification. For automotive applications requiring these certifications, ES3CH is the appropriate substitute. For non-automotive applications, ES3C is suitable for direct replacement.

Q: What is the difference between ES3C-13-F and ES3CHM6G?

A: ES3C-13-F (Diodes Incorporated) differs from ES3CHM6G in three parameters: forward voltage is 900 mV versus 950 mV at 3 A, reverse recovery time is 25 ns versus 35 ns, and the manufacturer is different. These represent improvements in switching characteristics. The part is not specified as automotive-grade. Compatibility depends on circuit requirements for forward voltage drop and switching speed.

Q: Why does ER3C_R1_00001 show lower reverse leakage current than the main part?

A: ER3C_R1_00001 specifies 1 µA reverse leakage at 150 V compared to 10 µA for ES3CHM6G. This represents superior leakage performance from Panjit International Inc. and may provide benefits in low-power or high-impedance circuit applications.

Q: What is the difference between SMC and SMB package options?

A: SMC (DO-214AB) and SMB (DO-214AA) are distinct surface mount package form factors with different physical dimensions and PCB footprints. ES3CHM6G, ES3C, ES3CH, ER3C_R1_00001, and ES3C-13-F use SMC packaging. ES3CB-13-F uses SMB packaging. Package selection is determined by PCB layout and assembly equipment compatibility.

Q: Is ES3CH the recommended substitute for ES3CHM6G?

A: ES3CH is the recommended substitute for applications requiring maintained automotive-grade classification and AEC-Q101 qualification. ES3CH provides parametric equivalence with identical electrical specifications and compliance certifications. For non-automotive applications, ES3C offers equivalent performance with higher inventory availability.

Q: Can ES3CB-13-F (SMB package) be used if the PCB is designed for SMC?

A: No. SMB (DO-214AA) and SMC (DO-214AB) packages have different physical dimensions and footprints. PCB layout and assembly equipment must be compatible with the selected package form factor. Substitution between package types requires PCB redesign.

Q: What inventory considerations apply to substitute selection?

A: ES3C offers the highest inventory availability at 10,200 pcs. ES3CH provides 832 pcs with automotive qualification. ER3C_R1_00001 provides 1,139 pcs. ES3C-13-F and ES3CB-13-F each provide over 10,300 pcs. Inventory levels should be evaluated against production volume and supply chain requirements.
