P0720SCRP Equivalent & Substitute Parts

Part Overview

The P0720SCRP is a 65V off-state, 400A peak pulse TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series, housed in a DO-214AA (SMB) surface mount package. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and procurement continuity. The part's primary function is transient voltage suppression in electronic circuits requiring high current pulse handling capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the P0720SCRP is determined by strict equivalence across the following critical parameters: off-state voltage (65V), peak pulse current rating (400A at 8/20µs), on-state voltage (4V), hold current (150mA), package type (DO-214AA, SMB), and surface mount configuration. Parts meeting these specifications are classified as direct substitutes regardless of manufacturer or series designation.

The identified substitutes are:

Direct Manufacturer Substitute (Littelfuse): P0720SCLRP — identical electrical specifications with active product status and improved compliance profile.

Cross-Manufacturer Substitute (STMicroelectronics): SMP100LC-65 — meets all critical electrical parameters with minor variations in breakover voltage (85V vs. 88V) and capacitance (90pF vs. 150pF), which remain within acceptable tolerance for TVS thyristor applications.

Parameter Comparison

Engineering Selection Recommendations

P0720SCLRP (Littelfuse Inc.) is the primary substitute for P0720SCRP. Both parts are manufactured by Littelfuse and share identical electrical specifications. P0720SCLRP maintains active product status and achieves ROHS3 compliance, addressing regulatory requirements that the obsolete P0720SCRP does not meet. This part is available in Tape & Reel packaging with substantial inventory (145,200 pcs).

SMP100LC-65 (STMicroelectronics) is a qualified cross-manufacturer alternative. It meets all critical electrical parameters with breakover voltage of 85V (within 3V of the original 88V) and reduced capacitance of 90pF (versus 150pF). Both parts maintain identical off-state voltage, peak pulse current ratings, and hold current specifications. SMP100LC-65 is ROHS3 compliant and REACH unaffected, with active product status and adequate inventory (55,100 pcs).

Selection between P0720SCLRP and SMP100LC-65 depends on design requirements regarding breakover voltage tolerance and capacitance specifications. For applications requiring exact capacitance matching, P0720SCLRP is preferred. For applications where reduced capacitance is acceptable or beneficial, SMP100LC-65 provides cross-manufacturer sourcing flexibility.

Frequently Asked Questions (FAQ)

Q: Can P0720SCLRP directly replace P0720SCRP in existing designs?

A: Yes. P0720SCLRP is electrically and mechanically identical to P0720SCRP, with the same voltage ratings, current specifications, on-state voltage, hold current, capacitance, and DO-214AA package. The primary difference is product status (active vs. obsolete) and improved RoHS compliance.

Q: What are the key differences between P0720SCLRP and SMP100LC-65?

A: Both parts share identical off-state voltage (65V), peak pulse current (400A at 8/20µs), hold current (150mA), and package type (DO-214AA, SMB). SMP100LC-65 has a breakover voltage of 85V (versus 88V) and capacitance of 90pF (versus 150pF). These differences are within acceptable tolerance for most TVS thyristor applications but should be verified against specific circuit requirements.

Q: Are there packaging differences between these substitutes?

A: P0720SCRP and P0720SCLRP are supplied in different packaging formats (unspecified for P0720SCRP; Tape & Reel for P0720SCLRP). SMP100LC-65 is supplied in Cut Tape and Digi-Reel® packaging. All three parts use the same DO-214AA (SMB) surface mount package for PCB assembly.

Q: Do all substitutes meet current regulatory compliance requirements?

A: P0720SCRP is RoHS non-compliant. Both P0720SCLRP and SMP100LC-65 are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component procurement.

Q: Which substitute should be selected for new designs?

A: For new designs, either P0720SCLRP or SMP100LC-65 is acceptable based on compliance requirements and design specifications. Both parts are active products with established supply chains. P0720SCLRP maintains exact electrical equivalence to the original part. SMP100LC-65 provides cross-manufacturer sourcing with minor parameter variations that are typically acceptable in TVS thyristor applications.
