Key Parameters

Substitute Part Grouping Explanation

Substitution of the ES3HBH is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 500 V
• Current - Average Rectified (Io): 3 A
• Voltage - Forward (Vf) (Max) @ If: 1.45 V @ 3 A
• Reverse Recovery Time (trr): 35 ns
• Current - Reverse Leakage @ Vr: 10 µA @ 500 V
• Capacitance @ Vr, F: 34 pF @ 4V, 1MHz

Mechanical Parameters (Must Match):

• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C

Compliance Parameters (Must Match):

• Technology: Standard
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

The ES3HB R5G meets all specified electrical, mechanical, and compliance requirements for direct substitution with the ES3HBH.

Engineering Selection Recommendations

ES3HBH (Primary Part): The ES3HBH is the recommended primary selection. This part maintains Active product status with established supply availability (930 pieces in stock). It carries automotive-grade qualification (AEC-Q101) and full ROHS3 compliance, meeting stringent regulatory and reliability requirements for automotive and industrial applications.

ES3HB R5G (Substitute Part): The ES3HB R5G is a parametric equivalent suitable for direct substitution. This part is listed as Discontinued at DiGi Electronics but maintains identical electrical specifications, mechanical compatibility, and compliance certifications. The ES3HB R5G is supplied in Cut Tape (CT) packaging with higher inventory availability (5735 pieces in stock). Selection of this substitute is appropriate when the primary part is unavailable or when Cut Tape packaging format is preferred for manufacturing processes.

Both parts are manufactured by Taiwan Semiconductor Corporation and share the same base product designation (ES3H series), ensuring design consistency and interchangeability within the specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can the ES3HB R5G replace the ES3HBH in existing designs?

A: Yes. The ES3HB R5G is a parametric equivalent with identical electrical ratings (500 V, 3 A, 35 ns reverse recovery time), forward voltage characteristics, and leakage specifications. Both parts use the DO-214AA (SMB) surface mount package and operate across the same temperature range (-55°C to 150°C). No circuit redesign is required.

Q: What is the difference between the ES3HBH and ES3HB R5G?

A: The primary differences are product status and packaging format. The ES3HBH is Active with standard packaging, while the ES3HB R5G is Discontinued at DiGi Electronics and supplied in Cut Tape (CT) format. All electrical and mechanical parameters are identical.

Q: Are both parts automotive-qualified?

A: The ES3HBH carries explicit automotive-grade qualification (AEC-Q101). The ES3HB R5G specifications do not list a separate grade designation in the provided data, though both parts share identical electrical characteristics and ROHS3 compliance. Verification of automotive qualification status for the ES3HB R5G should be confirmed with the manufacturer for applications requiring AEC-Q101 certification.

Q: What does the DO-214AA (SMB) package designation mean?

A: DO-214AA is the industry-standard surface mount package designation for this diode category, commonly referred to as SMB (Surface Mount Body). Both the ES3HBH and ES3HB R5G use this identical package, ensuring mechanical and thermal compatibility on printed circuit boards without modification to footprints or assembly processes.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. No compliance or regulatory differences exist between the ES3HBH and ES3HB R5G.

Q: What is the reverse recovery time specification, and why is it important?

A: Both parts specify a reverse recovery time (trr) of 35 nanoseconds, classifying them as fast recovery diodes. This parameter defines the time required for the diode to transition from forward conduction to reverse blocking state. The identical 35 ns specification ensures equivalent switching performance in rectification and power conversion circuits.
