S1JLS RVG Equivalent & Substitute Parts

Part Overview

The S1JLS RVG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 600 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 number experiences supply constraints, inventory limitations, or when design requirements permit selection from qualified alternatives that meet identical electrical and mechanical specifications. The parts listed below satisfy the core electrical parameters and package requirements of the S1JLS RVG.

Substitute Part Grouping Explanation

Substitution of rectifier diodes is determined by equivalence across the following critical parameters:

Reverse Voltage Rating (Vr): 600 V maximum
Average Rectified Current (Io): 1.2 A
Forward Voltage Drop (Vf): 1.3 V maximum at 1.2 A
Speed Classification: Fast Recovery ≤ 500ns for currents > 200mA
Reverse Leakage Current: 5 µA at 600 V
Package Type: SOD-123H with SOD-123HE supplier designation
Mounting Configuration: Surface Mount
Temperature Range: -55°C to 150°C junction operating range
Compliance: RoHS3 and REACH requirements

All substitute parts listed below meet these electrical and mechanical specifications and are therefore functionally interchangeable with the S1JLS RVG in applications where these parameters define the design requirement.

Engineering Selection Recommendations

S1JLSH (Taiwan Semiconductor Corporation)

The S1JLSH is a parametric equivalent to the S1JLS RVG manufactured by Taiwan Semiconductor Corporation. Both parts share identical electrical specifications, package designation, and compliance certifications. The S1JLSH maintains Active product status, indicating ongoing manufacturer support and availability. This substitute is suitable for direct replacement in all applications where the S1JLS RVG is specified.

RS1JFP (onsemi)

The RS1JFP is a parametric equivalent manufactured by onsemi that meets all core electrical and mechanical requirements of the S1JLS RVG. The RS1JFP carries Automotive grade qualification and AEC-Q101 certification, indicating suitability for automotive applications. However, the RS1JFP is designated as Not For New Designs, indicating that onsemi does not recommend this part for new product development. The RS1JFP is suitable for replacement in existing designs or legacy applications where the part is already in production, but should not be selected for new designs where alternatives are available.

Frequently Asked Questions (FAQ)

Q: Can the S1JLSH be used as a direct replacement for the S1JLS RVG?

A: Yes. The S1JLSH is a parametric equivalent with identical voltage rating (600 V), current rating (1.2 A), forward voltage drop (1.3 V @ 1.2 A), speed classification (Fast Recovery ≤ 500ns), reverse leakage current (5 µA @ 600 V), package type (SOD-123H), and operating temperature range (-55°C to 150°C). Both parts are manufactured by Taiwan Semiconductor Corporation and maintain Active product status with RoHS3 compliance.

Q: What is the difference between the S1JLS RVG and RS1JFP?

A: The S1JLS RVG and RS1JFP are electrically equivalent across all specified parameters. The primary differences are manufacturer (Taiwan Semiconductor Corporation versus onsemi) and product status (Active versus Not For New Designs). The RS1JFP includes automotive-grade qualification (AEC-Q101) and provides specified reverse recovery time (300 ns) and capacitance (18 pF @ 0V, 1MHz), whereas these parameters are not specified for the S1JLS RVG.

Q: Is the RS1JFP suitable for new product designs?

A: The RS1JFP carries a Not For New Designs designation from onsemi. This classification indicates that the manufacturer does not recommend this part for new product development. The RS1JFP is suitable for replacement in existing production designs or legacy applications, but alternative parts with Active status should be selected for new designs.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the SOD-123H package with SOD-123HE supplier designation and Surface Mount mounting type. PCB footprints designed for the S1JLS RVG are compatible with both the S1JLSH and RS1JFP without modification.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. The S1JLS RVG, S1JLSH, and RS1JFP are all RoHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for electronic components.

Q: What is the moisture sensitivity level for these diodes?

A: All three parts carry Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life and no special moisture control requirements during storage or handling.
