S1J-F Equivalent & Substitute Parts

Part Overview

The S1J-F is a general-purpose rectifier diode rated for 600 V DC reverse voltage and 1 A average rectified current in a surface mount SMA (DO-214AC) package. Manufactured by SMC Diode Solutions, this component is classified as obsolete. Due to its obsolete status and limited ongoing availability from the original manufacturer, identifying equivalent and substitute parts is necessary to maintain design continuity and ensure supply chain reliability for applications requiring this diode specification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the S1J-F are identified based on matching the following critical electrical and mechanical parameters:

• Voltage Rating: 600 V DC reverse voltage (Vr)
• Current Rating: 1 A average rectified current (Io)
• Forward Voltage: 1.1 V maximum at 1 A forward current
• Package Type: DO-214AC / SMA surface mount package
• Mounting Configuration: Surface mount technology

The substitute parts listed below meet these core electrical specifications and package requirements, enabling direct functional replacement in circuit designs. Variations in secondary parameters such as reverse recovery time, reverse leakage current, and operating temperature range are noted but do not preclude substitution when the primary ratings align.

Parameter Comparison

Engineering Selection Recommendations

GS1J (SURGE) is an active product with ROHS3 compliance and improved electrical characteristics compared to the S1J-F. The GS1J exhibits lower reverse recovery time (1 µs versus 2.5 µs) and reduced reverse leakage current (1 µA versus 5 µA), resulting in superior switching performance and lower standby current. The operating temperature range is narrower (-55°C to 150°C versus -65°C to 175°C), which may require verification for applications requiring extended low-temperature operation below -55°C or high-temperature operation above 150°C.

S1J (YAGEO) is an active product with ROHS3 compliance and parametric equivalence to the S1J-F. Complete electrical specifications are not provided for this part; however, the matching part number and active status indicate functional compatibility. This option is suitable for applications where detailed secondary parameter specifications are not critical to circuit performance.

Both substitute parts are actively manufactured and available in inventory, providing reliable alternatives to the obsolete S1J-F. Selection between GS1J and S1J should be based on application-specific requirements regarding operating temperature range and the availability of complete electrical specifications for design validation.

Frequently Asked Questions (FAQ)

Q: Can the GS1J directly replace the S1J-F in existing designs?

A: Yes. The GS1J meets the core electrical specifications of the S1J-F: 600 V reverse voltage rating, 1 A average rectified current, and 1.1 V forward voltage at 1 A. Both components use the DO-214AC (SMA) surface mount package with identical pinout and footprint. The GS1J is pin-compatible and functionally equivalent for circuit replacement.

Q: What are the differences between the GS1J and S1J-F?

A: The primary differences are product status and secondary electrical characteristics. The S1J-F is obsolete; the GS1J is active. The GS1J has faster reverse recovery time (1 µs versus 2.5 µs), lower reverse leakage current (1 µA versus 5 µA), and a narrower operating temperature range (-55°C to 150°C versus -65°C to 175°C). These differences result in improved switching performance and lower standby current consumption in the GS1J.

Q: Is the S1J (YAGEO) equivalent to the S1J-F?

A: Yes. The S1J shares the same base part number designation and is rated for 600 V reverse voltage, 1 A average rectified current, and 1.1 V forward voltage. It is packaged in DO-214AC format and is actively manufactured. Complete electrical specifications for secondary parameters are not provided; however, the matching core ratings and active status confirm functional equivalence.

Q: Are there temperature range limitations when substituting the GS1J for the S1J-F?

A: The GS1J operating temperature range is -55°C to 150°C, compared to the S1J-F range of -65°C to 175°C. Applications requiring junction temperatures below -55°C or above 150°C must verify that the GS1J meets the specific thermal requirements. For applications operating within the GS1J temperature range, no thermal limitations apply.

Q: Do the substitute parts have the same package footprint as the S1J-F?

A: Yes. Both the GS1J and S1J are specified in the DO-214AC (SMA) surface mount package, which is identical to the S1J-F package. PCB footprints, solder pad dimensions, and component placement are compatible without modification.

Q: Are the substitute parts RoHS compliant?

A: The GS1J and S1J are both ROHS3 compliant. The S1J-F RoHS status is not specified in the provided data. If RoHS compliance is required for your application, the GS1J and S1J are suitable alternatives.

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

A: All three parts—S1J-F, GS1J, and S1J—have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special moisture control requirements.
