P0080SC Equivalent & Substitute Parts

Part Overview

The P0080SC is a 6V off-state TVS thyristor manufactured by Littelfuse Inc. in the DO-214AA (SMB) package, designed for transient voltage suppression applications. This part is classified as obsolete, making identification of suitable alternatives necessary for ongoing design support and procurement. The P0080SC operates with a 25V breakover voltage and handles peak pulse currents of 400A (8/20µs), making it suitable for high-speed transient protection in compact surface-mount applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P0080SC are identified based on electrical and mechanical compatibility within the TVS thyristor category. The primary substitution criteria are:

Electrical Parameters: Off-state voltage, breakover voltage, peak pulse current rating (8/20µs), on-state voltage, and hold current must remain within acceptable operating ranges for the target application.

Mechanical Parameters: Package type (DO-214AA, SMB) and mounting configuration (surface mount) must match to ensure PCB compatibility without redesign.

Compliance Status: Active product status and current RoHS certification are preferred for long-term availability and regulatory compliance.

Two substitute parts meet these criteria with varying degrees of parameter alignment to the original P0080SC specification.

Engineering Selection Recommendations

P0080SCLRP (Direct Substitute): This part is the primary equivalent for the P0080SC. It maintains identical electrical specifications (6V off-state, 25V breakover, 400A peak pulse current, 260pF capacitance) and mechanical compatibility (DO-214AA, SMB package). The P0080SCLRP is active in production status with ROHS3 compliance, providing superior long-term availability and regulatory alignment compared to the obsolete P0080SC. This part is suitable for direct replacement without circuit modification.

SMP100LC-8 (Manufacturer Recommended Alternative): This STMicroelectronics part offers the same peak pulse current rating (400A) and package form factor (DO-214AA, SMB) but operates at 8V off-state and 15V breakover voltage. The SMP100LC-8 exhibits lower capacitance (75pF versus 260pF), which may affect circuit behavior in applications sensitive to parasitic capacitance. Selection of this part requires circuit-level evaluation to confirm voltage threshold compatibility with the target application. The SMP100LC-8 is active in production with ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can P0080SCLRP be used as a direct replacement for P0080SC? A: Yes. The P0080SCLRP maintains identical electrical parameters (6V off-state voltage, 25V breakover voltage, 400A peak pulse current) and mechanical specifications (DO-214AA, SMB package). No circuit modification is required.

Q: What are the key differences between P0080SCLRP and SMP100LC-8? A: Both parts share the same package (DO-214AA, SMB) and peak pulse current rating (400A). The primary differences are off-state voltage (6V versus 8V), breakover voltage (25V versus 15V), and capacitance (260pF versus 75pF). The SMP100LC-8 lower capacitance may impact circuit performance in applications where parasitic capacitance is a design constraint.

Q: Why is the P0080SC obsolete? A: The P0080SC is classified as obsolete by the manufacturer. The P0080SCLRP provides an active, production-supported alternative with identical specifications and improved regulatory compliance (ROHS3).

Q: Are both substitute parts available in the same packaging options? A: P0080SCLRP is available in Cut Tape (CT) and Digi-Reel packaging. SMP100LC-8 is available in Cut Tape (CT) and Digi-Reel packaging. Both support standard surface-mount assembly processes.

Q: Which substitute part should be selected for new designs? A: P0080SCLRP is recommended for new designs requiring exact electrical equivalence to the P0080SC. SMP100LC-8 may be considered if the application voltage thresholds (8V off-state, 15V breakover) and lower capacitance (75pF) are compatible with circuit requirements.
