ES1AL RTG Equivalent & Substitute Parts

Part Overview

The ES1AL RTG 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 ns, suitable for standard switching and rectification applications. The part maintains Active product status and is RoHS3 compliant 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. Alternative sources ensure design continuity and supply chain flexibility for applications requiring this diode specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ES1AL RTG 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
• Voltage - Forward (Vf) (Max) @ If: 950 mV @ 1 A

Allowable Parameter Variation: Reverse recovery time (trr) and junction capacitance may vary within the fast recovery classification (≤500 ns for currents >200 mA) without affecting functional substitution. Reverse leakage current and capacitance specifications remain within acceptable tolerance bands for general-purpose rectification applications.

The HS1AL RVG meets all mandatory equivalence criteria and is classified as a parametric equivalent substitute for the ES1AL RTG.

Engineering Selection Recommendations

ES1AL RTG (Primary Part): The ES1AL RTG is the original specification component with Active product status. This part exhibits a reverse recovery time of 35 ns, representing faster switching performance within the fast recovery classification. Selection of the ES1AL RTG is appropriate when the design baseline specifies this exact part number and supply availability permits.

HS1AL RVG (Substitute Part): The HS1AL RVG is a parametric equivalent substitute manufactured by the same supplier (Taiwan Semiconductor Corporation) with identical electrical ratings and package specifications. The reverse recovery time of 50 ns remains within the fast recovery specification (≤500 ns) and maintains functional equivalence for general-purpose rectification circuits. Both parts carry ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment. The HS1AL RVG is suitable for direct substitution in applications where the ES1AL RTG is specified, provided circuit design does not impose stricter reverse recovery time constraints below 50 ns.

Compliance and Certification: Both parts satisfy RoHS3 requirements and carry REACH Unaffected designation. Moisture sensitivity rating (MSL 1) indicates unlimited shelf life under standard storage conditions. ECCN classification (EAR99) and HTSUS code (8541.10.0080) are identical for both parts.

Frequently Asked Questions (FAQ)

Q: Can the HS1AL RVG replace the ES1AL RTG in all applications?

A: The HS1AL RVG is a parametric equivalent substitute with identical voltage, current, and package specifications. Substitution is valid for applications where the reverse recovery time specification does not require performance faster than 50 ns. If the circuit design mandates reverse recovery time ≤35 ns, the ES1AL RTG must be used.

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

A: The ES1AL RTG has a reverse recovery time of 35 ns, while the HS1AL RVG has 50 ns. Both values fall within the fast recovery classification (≤500 ns for currents >200 mA). The 15 ns difference is negligible for most general-purpose rectification applications but may be significant in high-frequency switching circuits.

Q: Are the packages identical?

A: Both parts use the DO-219AB package (Sub SMA) for surface mount applications. Mechanical footprint, lead spacing, and PCB land pattern are identical, enabling direct board-level substitution without layout modifications.

Q: What is the difference in packaging format?

A: The ES1AL RTG is supplied in standard packaging format, while the HS1AL RVG is supplied in Cut Tape (CT) format. Both formats contain the same component; the difference is in the delivery and handling method. Cut Tape format is suitable for automated pick-and-place assembly processes.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the ES1AL RTG and HS1AL RVG are ROHS3 compliant, REACH Unaffected, and carry identical ECCN (EAR99) and HTSUS classifications. Regulatory compliance is equivalent for both parts.

Q: What is the junction capacitance difference?

A: The ES1AL RTG has 10 pF capacitance at 1 V, 1 MHz, while the HS1AL RVG has 20 pF capacitance at 4 V, 1 MHz. These measurements are taken at different bias voltages and represent minor variations within acceptable tolerance for general-purpose rectifier applications. Capacitance differences do not affect substitution eligibility for standard rectification circuits.

Q: Can I use these parts interchangeably in my design?

A: Direct interchangeability is confirmed for applications where reverse recovery time ≤50 ns is acceptable. Verify that your circuit design does not impose stricter reverse recovery time requirements. If your application requires the faster 35 ns recovery time of the ES1AL RTG, substitution with the HS1AL RVG is not appropriate.
