P0300SARP Equivalent & Substitute Parts

Part Overview

The P0300SARP is a 25V off-state, 150A peak pulse (8/20µs) TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series, housed in a DO-214AA (SMB) surface mount package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the P0300SARP is determined by the following critical parameters: 25V off-state voltage, DO-214AA (SMB) package, surface mount configuration, and single-element thyristor topology. All substitute parts must maintain these core electrical and mechanical specifications to ensure functional compatibility in the original application circuit.

The P0300SALRP represents a direct equivalent from the same manufacturer with identical electrical ratings and active product status. The SMP100LC-25 and TISP4040H1BJR-S are manufacturer-recommended alternatives that exceed the peak pulse current capability (400A vs. 150A) while maintaining the 25V off-state voltage and DO-214AA package, providing enhanced transient protection margins.

Parameter Comparison

Engineering Selection Recommendations

The P0300SALRP is the primary direct substitute, offering identical electrical specifications with active product status and ROHS3 compliance. This part is recommended for applications requiring exact parameter matching and continued manufacturer support.

The SMP100LC-25 and TISP4040H1BJR-S are suitable alternatives for applications where increased peak pulse current capability (400A) provides design margin. Both parts maintain the 25V off-state voltage and DO-214AA package compatibility. The SMP100LC-25 features lower capacitance (65pF) and higher hold current (150mA), while the TISP4040H1BJR-S maintains the original 50mA hold current specification. Both alternatives carry ROHS3 compliance and active product status.

Frequently Asked Questions (FAQ)

Q: Can the P0300SALRP be used as a direct replacement for the P0300SARP?

A: Yes. The P0300SALRP is a direct equivalent with identical electrical ratings (25V off-state, 150A peak pulse 8/20µs, 50mA hold current) and the same DO-214AA package. The primary difference is active product status and ROHS3 compliance.

Q: What is the difference between the 150A and 400A peak pulse alternatives?

A: The SMP100LC-25 and TISP4040H1BJR-S provide 400A peak pulse capability compared to the original 150A specification. This represents a 2.67x increase in transient current handling. Both maintain the 25V off-state voltage and DO-214AA package, making them suitable for applications requiring enhanced protection margins.

Q: Are all substitute parts in the same package?

A: Yes. All substitute parts use the DO-214AA (SMB) surface mount package, ensuring mechanical and footprint compatibility with the original P0300SARP design.

Q: What compliance certifications apply to the substitute parts?

A: The P0300SALRP, SMP100LC-25, and TISP4040H1BJR-S all carry ROHS3 compliance. The SMP100LC-25 and TISP4040H1BJR-S are REACH Unaffected and REACH Affected respectively. All parts are classified as EAR99 for export control purposes.

Q: Does capacitance variation affect substitution compatibility?

A: Capacitance differences (140pF original vs. 65pF and 61pF for alternatives) may affect circuit performance in applications with specific frequency-dependent requirements. Circuit validation is necessary if capacitance is a critical design parameter.
