P4SMA180CA TR13 Equivalent & Substitute Parts

Part Overview

The P4SMA180CA TR13 is a transient voltage suppressor (TVS) diode manufactured by Central Semiconductor Corp, designed for general-purpose overvoltage protection in surface mount applications. This component features a 180V reverse standoff voltage with 292V maximum clamping voltage and 1.3A peak pulse current capability in an SMA package.

The P4SMA180CA TR13 is classified as obsolete. Identifying suitable substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production requirements for applications requiring equivalent transient voltage suppression performance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P4SMA180CA TR13 are identified based on matching the following critical electrical parameters:

• Voltage - Reverse Standoff (Typ): 180V
• Voltage - Breakdown (Min): 198V
• Voltage - Clamping (Max) @ Ipp: 292V
• Bidirectional Channels: 1
• Type: Zener
• Applications: General Purpose

The SMDJ180CA from Littelfuse qualifies as a direct substitute because it maintains identical voltage specifications (180V standoff, 198V breakdown, 292V clamping) and zener type classification. While the SMDJ180CA offers enhanced current handling (10.3A versus 1.3A) and power dissipation (3kW versus 400W), these represent performance improvements that do not compromise compatibility in applications designed for the original part's specifications.

Parameter Comparison

Engineering Selection Recommendations

The SMDJ180CA is an active, in-production substitute for the obsolete P4SMA180CA TR13. Both components share identical voltage protection specifications and zener diode classification, ensuring functional equivalence in transient suppression applications.

The SMDJ180CA carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The substitute part's extended operating temperature range (-65°C minimum versus -55°C) provides additional thermal margin.

Package differences exist: the P4SMA180CA uses DO-214AC (SMA), while the SMDJ180CA uses DO-214AB (SMC). PCB layout modifications may be required to accommodate the different footprint. The SMDJ180CA's superior current and power ratings (10.3A, 3kW) exceed the original specification and do not introduce compatibility issues in circuits designed for the lower-rated original component.

Frequently Asked Questions (FAQ)

Q: Can the SMDJ180CA directly replace the P4SMA180CA TR13 without circuit modifications?

A: The SMDJ180CA provides electrical equivalence for transient voltage suppression. However, the package change from SMA to SMC requires PCB footprint modification. The substitute's enhanced current and power ratings are compatible with applications designed for the original part.

Q: What is the primary reason for substitution?

A: The P4SMA180CA TR13 is obsolete. The SMDJ180CA is an active product with identical voltage specifications, ensuring continued availability for new production and design continuity.

Q: Are there compliance differences between the two parts?

A: Both parts carry EAR99 ECCN classification and identical HTSUS codes. The SMDJ180CA additionally provides ROHS3 compliance and REACH unaffected status, meeting current regulatory standards.

Q: How do package differences affect selection?

A: The P4SMA180CA uses SMA packaging (DO-214AC), while the SMDJ180CA uses SMC packaging (DO-214AB). These packages have different footprints and land patterns. PCB redesign is necessary if switching between these parts in existing designs.

Q: Does the higher current rating of the SMDJ180CA affect compatibility?

A: No. The SMDJ180CA's 10.3A peak pulse current and 3kW power dissipation exceed the original 1.3A and 400W specifications. These improvements maintain backward compatibility while providing enhanced transient protection capability.
