P0720SCMCLRP Equivalent & Substitute Parts

Part Overview

The P0720SCMCLRP is a 65V off-state, 400A peak pulse TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series. This component is designed for transient voltage suppression applications requiring high current handling capability in a compact DO-214AA surface mount package. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to supply constraints, design flexibility, or procurement optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P0720SCMCLRP is permissible when the following electrical and mechanical parameters are maintained within specification:

• Voltage - Off State: 65V (exact match required)
• Voltage - Breakover: within acceptable design tolerance (85V to 88V range)
• Current - Peak Pulse (8/20µs): 400A (exact match required)
• Current - Peak Pulse (10/1000µs): 100A (exact match required)
• Current - Hold (Ih): 150mA (exact match required)
• Package / Case: DO-214AA, SMB (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Number of Elements: 1 (exact match required)

The SMP100LC-65 from STMicroelectronics meets these substitution criteria with identical electrical performance in the critical parameters and compatible packaging.

Parameter Comparison

Engineering Selection Recommendations

Both the P0720SCMCLRP and SMP100LC-65 are active production components with full RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• Availability and lead time requirements
• Packaging preference (Tape & Reel versus Cut Tape & Digi-Reel®)
• Capacitance tolerance requirements (75pF versus 90pF)
• Supplier qualification and quality agreements

The breakover voltage difference of 3V (88V versus 85V) falls within typical design margins for TVS thyristor applications and does not preclude substitution when circuit design parameters accommodate this variation.

Frequently Asked Questions (FAQ)

Q: Can the SMP100LC-65 be used as a direct replacement for the P0720SCMCLRP?

A: Yes, the SMP100LC-65 meets the critical electrical specifications for substitution, including identical off-state voltage (65V), peak pulse current ratings (400A at 8/20µs and 100A at 10/1000µs), and hold current (150mA). Both components use the DO-214AA, SMB package and are surface mount compatible.

Q: What is the significance of the 3V breakover voltage difference?

A: The P0720SCMCLRP has a breakover voltage of 88V while the SMP100LC-65 is rated at 85V. This 3V difference is within typical design tolerances for TVS thyristor applications. Circuit design must accommodate this variation if precise breakover voltage is critical to system performance.

Q: Does the capacitance difference (75pF versus 90pF) affect substitution?

A: The capacitance difference of 15pF may impact high-frequency circuit behavior. Applications sensitive to parasitic capacitance should evaluate this parameter against specific circuit requirements before substitution.

Q: Are both parts available in the same packaging formats?

A: The P0720SCMCLRP is supplied in Tape & Reel (TR) format, while the SMP100LC-65 is available in Cut Tape (CT) and Digi-Reel® formats. Both use the DO-214AA, SMB package for surface mount assembly.

Q: Do both parts meet the same compliance standards?

A: Yes, both the P0720SCMCLRP and SMP100LC-65 are RoHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings.
