RS1DL RUG Equivalent & Substitute Parts

Part Overview

The RS1DL RUG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 200 V DC reverse voltage and 800 mA 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 150 ns, suitable for standard switching applications requiring efficient rectification at moderate current levels. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to address inventory availability, extended temperature range requirements, higher current capacity needs, or automotive-grade qualification requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RS1DL RUG is determined by the following critical parameters: DC reverse voltage rating (200 V minimum), package type (DO-219AB or Sub SMA equivalent), surface mount configuration, and fast recovery speed classification. The average rectified current rating establishes the primary substitution hierarchy: parts with equal or greater current capacity (800 mA or higher) are direct parametric equivalents, while parts with lower current ratings (500 mA) are classified as similar alternatives suitable only for reduced-load applications. All substitute parts maintain the 200 V reverse voltage specification and fast recovery characteristic. Operating temperature range, reverse recovery time, forward voltage characteristics, and reverse leakage current are secondary differentiators that determine suitability for specific application environments. RoHS3 compliance and MSL rating are maintained across all listed substitutes.

Parameter Comparison

Engineering Selection Recommendations

RS1DL (Parametric Equivalent): This part is a direct parametric equivalent to the RS1DL RUG, sharing identical electrical specifications, package configuration, and compliance certifications. Selection of RS1DL is appropriate when inventory of the RUG variant is unavailable. Both parts are manufactured by Taiwan Semiconductor Corporation and maintain ROHS3 compliance with unlimited moisture sensitivity rating.

RS07D-GS08 (Similar - Reduced Current Application): This Vishay part maintains the 200 V reverse voltage rating and fast recovery speed classification but is rated for 500 mA average rectified current. The RS07D-GS08 is suitable only for applications where the circuit load does not exceed 500 mA. This part carries automotive-grade qualification (AEC-Q101) and is appropriate for automotive applications requiring lower current capacity. Forward voltage is lower (1.15 V @ 700 mA) compared to the main part, resulting in reduced power dissipation in current-limited circuits.

VS-1EFH02-M3/I (Similar - Higher Current, Extended Temperature): This Vishay FRED Pt® series diode is rated for 1 A average rectified current, providing 25% higher current capacity than the RS1DL RUG. The operating temperature range extends to -65°C to 175°C, offering 25°C additional high-temperature capability. Reverse recovery time is significantly reduced to 16 ns, and reverse leakage current is lower at 2 µA. Selection is appropriate for applications requiring higher current handling or extended temperature operation without automotive qualification requirements.

VS-2EFH02HM3/I (Similar - Highest Current, Automotive Grade, Extended Temperature): This Vishay FRED Pt® series diode provides the highest current rating at 2 A, double the RS1DL RUG specification. The part includes automotive-grade qualification (AEC-Q101) and extended operating temperature range (-65°C to 175°C). Reverse recovery time is 25 ns, and reverse leakage current is 2 µA. Selection is appropriate for automotive applications requiring maximum current capacity and extended temperature performance.

Frequently Asked Questions (FAQ)

Q: Can RS1DL RUG be directly replaced with RS1DL?

A: Yes. RS1DL is a parametric equivalent with identical voltage rating (200 V), current rating (800 mA), forward voltage (1.3 V @ 800 mA), reverse recovery time (150 ns), and package configuration (DO-219AB). Both parts are ROHS3 compliant with unlimited moisture sensitivity rating. Substitution is direct without circuit modification.

Q: What is the difference between RS07D-GS08 and RS1DL RUG?

A: RS07D-GS08 is rated for 500 mA average rectified current compared to 800 mA for RS1DL RUG. Both maintain 200 V reverse voltage and fast recovery speed. RS07D-GS08 includes automotive-grade qualification (AEC-Q101) and exhibits lower forward voltage (1.15 V @ 700 mA). Substitution is appropriate only for applications with maximum current requirements not exceeding 500 mA.

Q: Can VS-1EFH02-M3/I or VS-2EFH02HM3/I be used in place of RS1DL RUG?

A: Yes, both Vishay parts are suitable substitutes. VS-1EFH02-M3/I provides 1 A current capacity with 16 ns reverse recovery time and extended temperature range (-65°C to 175°C). VS-2EFH02HM3/I provides 2 A current capacity with automotive qualification (AEC-Q101), 25 ns reverse recovery time, and extended temperature range. Both parts maintain the 200 V reverse voltage specification and DO-219AB package. Selection depends on current requirements and temperature operating range of the application.

Q: Are all substitute parts available in the same package?

A: Yes. All listed substitute parts use the DO-219AB package with surface mount configuration. RS1DL RUG uses Sub SMA designation, which is equivalent to DO-219AB. Package compatibility is confirmed across all substitutes.

Q: What is the significance of reverse recovery time differences?

A: Reverse recovery time (trr) affects switching speed and efficiency. RS1DL RUG and RS07D-GS08 have 150 ns trr, suitable for standard switching applications. VS-1EFH02-M3/I (16 ns) and VS-2EFH02HM3/I (25 ns) have significantly lower trr, resulting in faster switching transitions and reduced switching losses. Lower trr is beneficial in high-frequency switching circuits but is not required for standard rectification applications.

Q: Which substitute part is recommended for automotive applications?

A: RS07D-GS08 and VS-2EFH02HM3/I both carry automotive-grade qualification (AEC-Q101). RS07D-GS08 is suitable for automotive applications with maximum current requirements of 500 mA. VS-2EFH02HM3/I is suitable for automotive applications requiring up to 2 A current capacity and extended temperature operation (-65°C to 175°C).

Q: What is the impact of forward voltage differences on circuit performance?

A: Forward voltage affects power dissipation and voltage drop across the diode. RS1DL RUG has 1.3 V @ 800 mA. RS07D-GS08 has 1.15 V @ 700 mA (lower drop). VS-1EFH02-M3/I has 930 mV @ 1 A (significantly lower). VS-2EFH02HM3/I has 950 mV @ 2 A (significantly lower). Lower forward voltage reduces power dissipation and heat generation, beneficial in high-current or thermally constrained applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts, including RS1DL, RS07D-GS08, VS-1EFH02-M3/I, and VS-2EFH02HM3/I, are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).
