RSB12JS2T2R Equivalent & Substitute Parts

Part Overview

The RSB12JS2T2R is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by Rohm Semiconductor, designed for general-purpose overvoltage protection applications. This surface-mount component operates with a 9V reverse standoff voltage and is housed in an EMD6 package (SOT-563/SOT-666 footprint). The part maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified based on matching electrical characteristics, package compatibility, and functional equivalence for transient voltage suppression in circuit protection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RSB12JS2T2R are identified based on the following critical parameters that determine functional equivalence:

Electrical Compatibility Criteria:

• Bidirectional channel configuration (2 channels required)
• Voltage - Reverse Standoff rating within acceptable tolerance of 9V
• Voltage - Breakdown minimum rating at or above 9.6V
• Zener diode type classification
• General-purpose transient voltage suppression application suitability

Mechanical & Package Compatibility:

• Surface-mount mounting type
• SOT-563 or SOT-666 package footprint compatibility
• Tape & Reel (TR) packaging format

Compliance & Regulatory Alignment:

• Active product status
• RoHS3 compliance
• REACH unaffected status
• MSL 1 rating

The SP3006-02XTG from Littelfuse Inc. qualifies as a substitute based on matching bidirectional channel count, compatible package footprint (SOT-563), surface-mount configuration, and equivalent regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the RSB12JS2T2R and SP3006-02XTG maintain Active product status, ensuring continued availability and manufacturer support. Both components are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement. Both carry MSL 1 ratings, indicating unlimited shelf life under standard storage conditions.

The SP3006-02XTG is available in higher inventory quantity (12,900 pcs) compared to the RSB12JS2T2R (45,727 pcs), which may influence supply chain decisions. Both parts are packaged in Tape & Reel format suitable for automated assembly processes and share compatible SOT-563/SOT-666 footprints for direct PCB layout compatibility.

Selection between these parts should be based on application-specific voltage and current requirements, as the SP3006-02XTG provides specified clamping voltage (15V Typ) and peak pulse current (2A at 8/20µs) parameters, whereas the RSB12JS2T2R does not specify these values in the provided data.

Frequently Asked Questions (FAQ)

Q: Can the SP3006-02XTG directly replace the RSB12JS2T2R on existing PCBs?

A: Yes, direct PCB replacement is possible. Both components use compatible SOT-563/SOT-666 package footprints and share identical bidirectional channel configuration (2 channels). Surface-mount placement and solder reflow processes are identical.

Q: What are the key electrical differences between these parts?

A: The RSB12JS2T2R specifies a 9V reverse standoff voltage with 9.6V minimum breakdown. The SP3006-02XTG specifies a 6V maximum reverse standoff voltage with 9V minimum breakdown. The SP3006-02XTG provides additional specification data including 15V typical clamping voltage and 2A peak pulse current at 8/20µs pulse width.

Q: Are both parts suitable for the same applications?

A: Both parts are classified for general-purpose transient voltage suppression. Application suitability depends on specific circuit voltage levels, transient pulse characteristics, and current handling requirements. The SP3006-02XTG's specified current rating (2A at 8/20µs) provides explicit guidance for pulse-based protection scenarios.

Q: Do packaging and compliance certifications differ between these parts?

A: No. Both parts are supplied in Tape & Reel (TR) packaging, maintain RoHS3 compliance, carry REACH unaffected status, and hold MSL 1 ratings. Moisture sensitivity and regulatory compliance are equivalent.

Q: Which part should be selected for new designs?

A: Selection should be based on application voltage and current requirements. The SP3006-02XTG's fully specified electrical parameters (clamping voltage and peak pulse current) make it suitable for applications where these characteristics are critical design inputs. Both parts maintain Active status and equivalent regulatory compliance.
