S1MLSHRVG Equivalent & Substitute Parts

Part Overview

The S1MLSHRVG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 1000 V DC reverse voltage and 1.2 A average rectified current in a surface mount SOD-123HE package. This component is classified as Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit selection from qualified alternative manufacturers. The S1MLSHRVG maintains parametric equivalence with specific substitute diodes that share identical electrical ratings and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the S1MLSHRVG is permitted with the RS1MFP manufactured by onsemi based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 1000 V
• Current - Average Rectified (Io): 1.2 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1.2 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 5 µA @ 1000 V
• Package / Case: SOD-123H
• Supplier Device Package: SOD-123HE
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

These parameters define the functional and physical compatibility envelope for direct substitution in applications requiring a 1 kV, 1.2 A general-purpose rectifier diode in SOD-123HE surface mount packaging.

Engineering Selection Recommendations

S1MLSHRVG (Primary Selection)

The S1MLSHRVG maintains Active product status, indicating ongoing manufacturer support and availability. This part is the preferred selection for new designs and applications requiring long-term supply assurance. The component is RoHS3 compliant and carries unlimited moisture sensitivity level, suitable for standard manufacturing and storage conditions.

RS1MFP (Substitute Selection)

The RS1MFP is electrically and mechanically equivalent to the S1MLSHRVG across all critical parameters. However, this part carries a "Not For New Designs" product status designation. The RS1MFP is qualified to AEC-Q101 automotive standards and carries an Automotive grade classification, providing additional qualification documentation for applications requiring automotive-level reliability.

Selection of RS1MFP is appropriate for:

• Replacement and repair applications where the original part is unavailable
• Existing designs already qualified with this substitute
• Applications benefiting from automotive-grade qualification and AEC-Q101 compliance

The RS1MFP should not be selected for new design implementations due to its Not For New Designs status, unless specific automotive qualification requirements mandate its use.

Frequently Asked Questions (FAQ)

Q: Can the RS1MFP directly replace the S1MLSHRVG in existing designs?

A: Yes. The RS1MFP is parametrically equivalent across all critical electrical and mechanical specifications: 1000 V reverse voltage, 1.2 A average rectified current, 1.3 V forward voltage drop, fast recovery speed classification, and SOD-123HE surface mount packaging. Direct substitution is supported without circuit modification.

Q: What is the significance of the "Not For New Designs" status on the RS1MFP?

A: This designation indicates that onsemi does not recommend the RS1MFP for new product development. The part remains available for replacement and repair applications. New designs should prioritize the S1MLSHRVG, which carries Active product status and ensures long-term manufacturer support.

Q: Are there package compatibility considerations between these parts?

A: Both parts use identical packaging: SOD-123H case with SOD-123HE supplier device package designation. Surface mount footprints, lead spacing, and solder pad dimensions are identical. No PCB layout modifications are required for substitution.

Q: Does the RS1MFP's automotive qualification affect its use in non-automotive applications?

A: No. Automotive qualification (AEC-Q101) and Automotive grade classification represent additional qualification layers. These certifications do not restrict use in non-automotive applications. The RS1MFP remains suitable for general-purpose rectification across all application categories.

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

A: The RS1MFP specifies a reverse recovery time (trr) of 300 ns. The S1MLSHRVG does not provide a specific trr value but is classified as Fast Recovery with a maximum of 500 ns for currents exceeding 200 mA. Both parts meet the fast recovery speed classification requirement.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the S1MLSHRVG and RS1MFP are RoHS3 compliant with unlimited moisture sensitivity level (MSL 1). Both parts are suitable for lead-free soldering processes and standard manufacturing environments without special handling requirements.

Q: What is the operating temperature range for these diodes?

A: Both parts operate across a junction temperature range of -55°C to 150°C. This range supports applications in industrial, commercial, and automotive temperature environments.
