ES1HL Equivalent & Substitute Parts

Part Overview

The ES1HL is a 500V, 1A super fast recovery diode manufactured by Taiwan Semiconductor Corporation, packaged in SOD-123 surface mount configuration. This component is classified as not for new designs, indicating it has been superseded in the manufacturer's product line. The ES1HL remains in inventory and available for legacy system support, repair, and maintenance applications where existing designs require this specific part number or equivalent functionality.

Identifying suitable substitute parts is necessary for applications where the ES1HL reaches end-of-life status, inventory depletion, or when design flexibility permits component optimization while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ES1HL is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Reverse voltage rating must equal or exceed 500V
• Average rectified current must equal or exceed 1A
• Forward voltage drop must not exceed 1.7V at 1A
• Reverse recovery time must not exceed 35ns (fast recovery classification)
• Reverse leakage current must not exceed 5µA at rated reverse voltage

Mechanical Compatibility Criteria:

• Surface mount package type (SOD-123 or compatible variants)
• Operating temperature range must encompass -55°C to 150°C minimum
• RoHS3 compliance required
• MSL rating of 1 (Unlimited) required

The ES1JLW qualifies as a direct substitute because it meets or exceeds all electrical parameters while maintaining surface mount compatibility and regulatory compliance. The ES1JLW provides enhanced reverse voltage capability (600V versus 500V) and extended junction temperature range (-55°C to 175°C versus -55°C to 150°C), making it suitable for applications requiring the ES1HL's electrical characteristics.

Engineering Selection Recommendations

ES1HL Selection: The ES1HL is suitable for legacy system maintenance and repair where existing designs are locked to this specific part number. This component remains in stock with 10,400 pieces available. The ES1HL carries ROHS3 compliance and unlimited moisture sensitivity rating, meeting current regulatory requirements for existing applications.

ES1JLW Selection: The ES1JLW is the manufacturer-recommended substitute and is classified as an active product. With 62,371 pieces in inventory, this part provides superior availability for ongoing production and new applications. The ES1JLW maintains identical electrical performance at the ES1HL's rated specifications while offering enhanced reverse voltage capability (600V) and extended operating temperature range (-55°C to 175°C). The ES1JLW carries ROHS3 compliance and unlimited moisture sensitivity rating.

The ES1JLW is appropriate for applications where component obsolescence risk must be minimized or where the enhanced voltage and temperature ratings provide design margin benefits. Both parts are manufactured by Taiwan Semiconductor Corporation and share identical forward voltage characteristics and reverse recovery time specifications.

Frequently Asked Questions (FAQ)

Q: Can the ES1JLW directly replace the ES1HL in existing designs?

A: Yes. The ES1JLW meets or exceeds all electrical parameters of the ES1HL. Both parts share identical forward voltage (1.7V @ 1A) and reverse recovery time (35ns) specifications. The ES1JLW provides higher reverse voltage rating (600V versus 500V) and extended junction temperature range (-55°C to 175°C versus -55°C to 150°C). Surface mount mounting type is identical for both parts.

Q: What is the difference between SOD-123 and SOD-123W packages?

A: Both are surface mount packages for diode applications. The SOD-123W is a variant of the SOD-123 package. Physical compatibility depends on PCB layout and footprint design. Verify that the target PCB footprint accommodates the SOD-123W package dimensions if substituting the ES1HL (SOD-123) with the ES1JLW (SOD-123W).

Q: Are both parts RoHS compliant?

A: Yes. Both the ES1HL and ES1JLW are ROHS3 compliant and carry unlimited moisture sensitivity level (MSL 1) ratings, meeting current regulatory requirements for electronic component manufacturing and assembly.

Q: Why is the ES1HL marked as "Not For New Designs"?

A: The ES1HL has been superseded by the ES1JLW in the manufacturer's product line. The "Not For New Designs" designation indicates that Taiwan Semiconductor Corporation recommends using the ES1JLW for new applications. The ES1HL remains available for legacy system support and maintenance.

Q: What are the key electrical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by reverse voltage rating (must equal or exceed 500V), average rectified current (must equal or exceed 1A), forward voltage drop (must not exceed 1.7V @ 1A), reverse recovery time (must not exceed 35ns), and reverse leakage current (must not exceed 5µA at rated reverse voltage). The ES1JLW satisfies all these criteria.

Q: Is the ES1JLW the only available substitute for the ES1HL?

A: Based on the provided data, the ES1JLW is the manufacturer-recommended substitute listed for the ES1HL. This part meets all electrical and mechanical compatibility requirements for direct substitution.
