P1300SCMC Equivalent & Substitute Parts

Part Overview

The P1300SCMC is a 120V off-state, 400A peak pulse TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series, housed in a DO-214AA SMB package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The part delivers transient voltage suppression through a thyristor topology with 160V breakover voltage and 5V on-state voltage characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the P1300SCMC is determined by matching the following critical electrical and mechanical parameters:

• Voltage - Breakover: 160V
• Voltage - Off State: 120V
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Current - Hold (Ih): 150mA

The P1300SCMCLRP is a direct equivalent from Littelfuse Inc., differing only in packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete). The SMTPA120 from STMicroelectronics is a manufacturer-recommended alternative that maintains the same voltage ratings and package but operates at reduced peak pulse current levels (150A versus 400A at 8/20µs).

Parameter Comparison

Engineering Selection Recommendations

The P1300SCMCLRP is the direct functional equivalent and primary substitute for the obsolete P1300SCMC. Both parts maintain identical electrical specifications and package configuration. The P1300SCMCLRP carries Active product status and ROHS3 compliance, making it suitable for new designs and production environments with regulatory requirements.

The SMTPA120 from STMicroelectronics is a manufacturer-recommended alternative that maintains voltage compatibility but operates at reduced peak pulse current ratings. Selection of the SMTPA120 is appropriate only when circuit requirements permit operation at 150A peak pulse current (8/20µs) instead of 400A. This part also carries ROHS3 compliance and Active product status.

Frequently Asked Questions (FAQ)

Q: Can the P1300SCMCLRP directly replace the P1300SCMC?

A: Yes. The P1300SCMCLRP is electrically and mechanically identical to the P1300SCMC. The difference is packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete).

Q: What are the limitations of using SMTPA120 as a substitute?

A: The SMTPA120 operates at reduced peak pulse current levels: 150A at 8/20µs and 50A at 10/1000µs, compared to 400A and 100A respectively for the P1300SCMC. Additionally, capacitance is reduced from 60pF to 30pF. Use SMTPA120 only when circuit design permits these reduced current ratings.

Q: Are all substitute parts RoHS compliant?

A: The P1300SCMC is RoHS non-compliant. Both P1300SCMCLRP and SMTPA120 are ROHS3 compliant, meeting current regulatory requirements for new production.

Q: Do all parts use the same package?

A: Yes. All three parts use the DO-214AA SMB surface mount package, ensuring mechanical and footprint compatibility.

Q: What is the hold current specification across all parts?

A: All three parts maintain an identical hold current (Ih) of 150mA, ensuring consistent triggering behavior in circuit applications.
