Substitute Part Grouping Explanation

Substitution of the ES2CAHM2G is determined by the following critical parameters:

Parametric Equivalents maintain identical electrical specifications across all key parameters: 150 V reverse voltage rating, 2 A average rectified current, 950 mV forward voltage drop at 2 A, 35 ns reverse recovery time, 10 µA reverse leakage current at 150 V, and 25 pF capacitance. These parts are functionally interchangeable with the main part number.

Similar Parts share the same package format (DO-214AC/SMA) and voltage rating (150 V) but differ in one or more of the following: current rating, forward voltage characteristics, reverse leakage current, capacitance, or diode technology (Schottky versus Standard). These parts are suitable for applications where the specified current rating or other electrical characteristics are compatible with circuit requirements, but direct pin-for-pin substitution requires circuit-level verification.

The grouping is based strictly on the following allowed parameters:

Voltage - DC Reverse (Vr) (Max)
Current - Average Rectified (Io)
Voltage - Forward (Vf) (Max) @ If
Reverse Recovery Time (trr)
Current - Reverse Leakage @ Vr
Capacitance @ Vr, F
Package / Case

Engineering Selection Recommendations

Parametric Equivalents (Direct Replacements)

ES2CA and ES2CAH are parametric equivalents of the ES2CAHM2G. Both parts are manufactured by Taiwan Semiconductor Corporation and maintain identical electrical specifications across all critical parameters. ES2CAH carries automotive-grade qualification with AEC-Q101 certification, matching the original part's qualification status. ES2CA is available in Tape & Reel packaging. Both parts are ROHS3 compliant and REACH unaffected. These parts are suitable for direct substitution in applications requiring the full 2 A current rating and 150 V reverse voltage specification.

Similar Parts for Current-Reduced Applications

ES1C-13-F (Diodes Incorporated) and ES1C-E3/5AT and ES1C-E3/61T (Vishay General Semiconductor) are standard-technology diodes rated for 1 A average rectified current at 150 V reverse voltage. These parts are suitable for applications where the circuit current requirement does not exceed 1 A. All three parts maintain the same operating temperature range (-55°C to 150°C) and package format as the main part. These parts are ROHS3 compliant and REACH unaffected.

Similar Parts for Higher Current Applications

CDBA2150-HF (Comchip Technology) is a Schottky diode rated for 2 A at 150 V, matching the current rating of the ES2CAHM2G. This part features lower forward voltage drop (870 mV @ 2 A versus 950 mV @ 2 A) and is suitable for applications where reduced power dissipation is beneficial. CDBA3150-HF and CDBA5150-HF provide 3 A and 5 A current ratings respectively at 150 V, suitable for applications requiring higher current capacity. All Comchip parts are ROHS3 compliant and REACH unaffected. Comchip Schottky devices operate across an extended temperature range (-50°C to 175°C).

Compliance and Certification Status

All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the original ES2CAHM2G. The ES2CAH variant includes automotive-grade qualification with AEC-Q101 certification, identical to the main part. Standard-technology alternatives (ES1C series) and Schottky alternatives (CDBA series) are all suitable for general industrial and automotive applications based on their compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can ES2CA or ES2CAH be used as direct replacements for ES2CAHM2G?

A: Yes. ES2CA and ES2CAH are parametric equivalents with identical electrical specifications: 150 V reverse voltage, 2 A average rectified current, 950 mV forward voltage drop at 2 A, 35 ns reverse recovery time, and 10 µA reverse leakage current. Both parts are available in the same DO-214AC package. ES2CAH includes automotive-grade AEC-Q101 qualification matching the original part.

Q: What is the difference between the ES2CAHM2G and the Comchip CDBA2150-HF?

A: Both parts are rated for 150 V reverse voltage and 2 A average rectified current in DO-214AC packages. The primary differences are: (1) Technology type—ES2CAHM2G uses standard rectifier diode technology while CDBA2150-HF uses Schottky technology; (2) Forward voltage drop—CDBA2150-HF has lower forward voltage (870 mV @ 2 A versus 950 mV @ 2 A), resulting in lower power dissipation; (3) Reverse leakage current—CDBA2150-HF has higher reverse leakage (500 µA @ 150 V versus 10 µA @ 150 V); (4) Operating temperature range—CDBA2150-HF operates to 175°C versus 150°C for the original part.

Q: Can I use a 1 A rated diode (ES1C series) in place of the 2 A ES2CAHM2G?

A: Only if the circuit current requirement does not exceed 1 A. The ES1C-13-F, ES1C-E3/5AT, and ES1C-E3/61T are all rated for maximum 1 A average rectified current. Using a 1 A part in a circuit designed for 2 A operation will result in device overstress and failure. These parts are suitable only for applications with reduced current requirements.

Q: What are the advantages of Schottky diodes (CDBA series) over standard rectifier diodes?

A: Schottky diodes exhibit lower forward voltage drop (typically 870 mV versus 950 mV at rated current), resulting in reduced power dissipation and improved efficiency. However, Schottky diodes have higher reverse leakage current (500 µA versus 10 µA at rated voltage). Schottky technology is beneficial in high-frequency switching applications and low-voltage power supplies where efficiency is critical.

Q: Are all substitute parts available in the same packaging as the ES2CAHM2G?

A: All listed substitute parts use the DO-214AC (SMA) surface mount package, identical to the ES2CAHM2G. Packaging variations exist only in tape format (Tape & Reel, Cut Tape & Digi-Reel, or bulk), which do not affect electrical performance or board-level compatibility.

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

A: AEC-Q101 is an automotive electronics qualification standard. Parts meeting this qualification have undergone rigorous testing for reliability and performance in automotive applications. ES2CAH and the original ES2CAHM2G both carry AEC-Q101 qualification. Comchip CDBA series parts do not list AEC-Q101 qualification in the provided specifications.

Q: Can I use a higher voltage rated diode (e.g., 200 V) in place of the 150 V ES2CAHM2G?

A: Yes, from an electrical standpoint. A diode rated for higher reverse voltage can be used in circuits designed for lower voltage operation. However, higher voltage rated diodes typically exhibit different forward voltage characteristics and capacitance values. Circuit-level analysis is required to ensure compatibility with specific application requirements.

Q: What is the difference between ES2CA and ES2CAH?

A: Both parts are parametric equivalents with identical electrical specifications. The primary difference is qualification status: ES2CAH includes automotive-grade AEC-Q101 qualification while ES2CA does not list this qualification in the provided specifications. ES2CAH is preferred for automotive applications requiring AEC-Q101 compliance.
