TVB360RSC-L Equivalent & Substitute Parts

Part Overview

The TVB360RSC-L is a 360V off-state, 400A peak pulse (8/20µs) transient voltage suppressor thyristor manufactured by Littelfuse in the DO-214AA (SMB) package. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement.

The TVB360RSC-L operates within the SiBar series and is designed for surface mount applications requiring high-current transient suppression. Due to its obsolete status, equivalent parts from active product lines must be evaluated based on electrical performance parameters and package compatibility.

Substitute Part Grouping Explanation

Substitution of the TVB360RSC-L is determined by the following electrical and mechanical criteria:

Primary Substitution Criteria:

• Voltage - Off State: Must match or be lower than 360V to maintain protection threshold
• Voltage - Breakover: Must be compatible with circuit protection requirements
• Current - Peak Pulse (8/20µs): Must equal or exceed 400A to handle transient events
• Package / Case: Must be DO-214AA (SMB) or compatible surface mount package
• Mounting Type: Surface mount configuration required
• Number of Elements: Single element configuration

Substitute Parts Identified:

P3500SCLRP (Littelfuse SIDACtor®): Meets primary substitution criteria with 320V off-state voltage, 400A peak pulse current (8/20µs), and DO-214AA package. Active product status with higher inventory availability.

TISP4080L3AJR-S and TISP4080M3AJR-S (Bourns): These parts operate at significantly lower voltage ratings (65V off-state) and are packaged in DO-214AC (SMA), representing a different application class. These are not direct electrical equivalents for the TVB360RSC-L.

Parameter Comparison

Engineering Selection Recommendations

P3500SCLRP is the primary equivalent for TVB360RSC-L replacement. This part maintains electrical compatibility with 400A peak pulse current (8/20µs) and operates at a lower off-state voltage (320V vs. 360V), providing equivalent or enhanced protection margins. Both parts share the DO-214AA (SMB) package, eliminating PCB layout modifications. P3500SCLRP carries active product status with ROHS3 compliance and REACH unaffected classification, matching the regulatory profile of the obsolete TVB360RSC-L.

TISP4080L3AJR-S and TISP4080M3AJR-S are not suitable direct replacements. These Bourns components operate at 65V off-state voltage, representing a different application class for lower-voltage transient suppression. The DO-214AC (SMA) package differs from the TVB360RSC-L's DO-214AA (SMB) footprint, requiring PCB redesign. These parts are appropriate only for circuits designed for 65V protection levels.

Frequently Asked Questions (FAQ)

Q: Can P3500SCLRP directly replace TVB360RSC-L without PCB modifications?

A: Yes. Both parts use the DO-214AA (SMB) package with identical pinout and footprint. No PCB layout changes are required. The lower off-state voltage (320V vs. 360V) provides equivalent protection for circuits designed for the TVB360RSC-L.

Q: Why are TISP4080L3AJR-S and TISP4080M3AJR-S listed as substitutes if they operate at 65V?

A: These parts are listed based on the provided substitute data but are not electrical equivalents for high-voltage applications. They are suitable only for circuits requiring 65V transient suppression and would require complete circuit redesign if substituted for the TVB360RSC-L.

Q: What is the impact of the 40V difference in off-state voltage between TVB360RSC-L (360V) and P3500SCLRP (320V)?

A: The lower off-state voltage of P3500SCLRP (320V) triggers protection at a lower threshold, providing faster response to transient events. This is acceptable for applications where the original 360V threshold was not a critical design constraint.

Q: Are there compliance differences between TVB360RSC-L and P3500SCLRP?

A: Both parts are ROHS3 compliant and REACH unaffected. Regulatory compliance is equivalent. P3500SCLRP's active product status ensures ongoing availability and support compared to the obsolete TVB360RSC-L.

Q: What package considerations apply when selecting a substitute?

A: The DO-214AA (SMB) package used by TVB360RSC-L and P3500SCLRP is physically and electrically identical. The DO-214AC (SMA) package used by the Bourns parts is smaller and has different pinout, requiring PCB redesign and is not recommended for direct substitution.
