ES1AL MTG Equivalent & Substitute Parts

Part Overview

The ES1AL MTG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 50 V DC reverse voltage and 1 A average rectified current in a Sub SMA surface mount package. This component is classified as a fast recovery diode with a reverse recovery time of 35 nanoseconds, suitable for applications requiring rapid switching characteristics. The part maintains Active product status and carries full RoHS3 compliance with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across critical parameters including voltage rating, current capacity, package type, and thermal operating range. Identification of alternatives ensures design flexibility and supply chain continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the ES1AL MTG is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 50 V
• Current - Average Rectified (Io): 1 A
• Package / Case: DO-219AB (Sub SMA)
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant

Performance Parameters:

• Voltage - Forward (Vf) (Max) @ If: 950 mV @ 1 A
• Current - Reverse Leakage @ Vr: 5 µA @ 50 V
• Technology: Standard

The HS1AL RVG meets all mandatory equivalence criteria and maintains identical electrical performance specifications for voltage, current, and thermal operating range. Both components are manufactured by Taiwan Semiconductor Corporation and share the same DO-219AB package designation with Sub SMA supplier device package classification.

Parameter Comparison

Engineering Selection Recommendations

Both ES1AL MTG and HS1AL RVG are Active products manufactured by Taiwan Semiconductor Corporation with full ROHS3 compliance and REACH Unaffected status. Selection between these components is based on application-specific requirements and supply availability.

ES1AL MTG is specified when faster reverse recovery time (35 ns) is required for high-frequency switching applications or when lower junction capacitance (10 pF @ 1 V) is critical to circuit performance.

HS1AL RVG is specified when standard packaging formats (Cut Tape) align with procurement workflows or when the slightly higher reverse recovery time (50 ns) and capacitance (20 pF @ 4 V) are acceptable within application tolerances. This part maintains identical voltage, current, and thermal ratings.

Both components are suitable for direct substitution in applications where the specified electrical parameters are the primary selection criteria. Compliance certifications and product status are equivalent across both options.

Frequently Asked Questions (FAQ)

Q: Can HS1AL RVG replace ES1AL MTG in existing designs?

A: Yes. Both components share identical voltage ratings (50 V), current capacity (1 A), forward voltage drop (950 mV @ 1 A), reverse leakage current (5 µA @ 50 V), package type (DO-219AB Sub SMA), and operating temperature range (-55°C to 150°C). Substitution is electrically and mechanically compatible.

Q: What is the difference in reverse recovery time between these parts?

A: ES1AL MTG has a reverse recovery time of 35 nanoseconds, while HS1AL RVG has 50 nanoseconds. This 15 nanosecond difference may be significant in high-frequency switching applications but is negligible in standard rectification circuits.

Q: Are there packaging differences between ES1AL MTG and HS1AL RVG?

A: Both components use the DO-219AB package with Sub SMA supplier designation for surface mount applications. The primary packaging difference is that HS1AL RVG is supplied in Cut Tape (CT) format, while ES1AL MTG packaging format is not specified in available data. This affects handling and assembly processes but not electrical or mechanical compatibility.

Q: Do both parts meet current compliance requirements?

A: Yes. Both ES1AL MTG and HS1AL RVG are ROHS3 compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. Both maintain Active product status with equivalent regulatory standing.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For applications requiring faster switching response, ES1AL MTG is specified. For applications where standard recovery time is acceptable and Cut Tape packaging is preferred, HS1AL RVG is specified. Both are equally valid for general-purpose rectification at 50 V and 1 A ratings.

Q: Is there a capacitance difference that affects circuit design?

A: Yes. ES1AL MTG has 10 pF capacitance at 1 V, while HS1AL RVG has 20 pF at 4 V. In high-frequency or precision timing circuits, this difference may require circuit verification, though both values are typical for this diode category.
