P4KE130C-B Equivalent & Substitute Parts

Part Overview

The P4KE130C-B is a transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This component features a 111V reverse standoff voltage with a 187.95V maximum clamping voltage and 2.3A peak pulse current capability in a through-hole DO-204AL (DO-41) package. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution for the P4KE130C-B is determined by strict equivalence across the following critical parameters:

Reverse standoff voltage: 111V (identical across all candidates)
Peak pulse current: 2.3A (identical across all candidates)
Power dissipation: 400W (identical across all candidates)
Operating temperature range: -55°C to 175°C (identical across all candidates)
Package type: DO-204AL (DO-41) through-hole axial configuration (identical across all candidates)
Bidirectional channels: 1 (identical across all candidates)
Device type: Zener TVS diode (identical across all candidates)

The identified substitute parts P4KE130CA and P4KE130CA-B maintain all critical electrical and mechanical parameters. Variations in clamping voltage (179V versus 187.95V) and breakdown voltage minimums fall within the functional tolerance band for general-purpose transient suppression applications where the standoff voltage and peak current ratings are the primary selection criteria.

Engineering Selection Recommendations

Both P4KE130CA and P4KE130CA-B are functionally equivalent substitutes for the obsolete P4KE130C-B. Selection between alternatives should be based on the following criteria:

P4KE130CA-B (Littelfuse Inc., Bulk packaging) provides continuity with the original manufacturer while offering active product status and full compliance certifications including ROHS3 and REACH Unaffected designation. This option is recommended for designs requiring manufacturer consistency and maximum regulatory documentation.

P4KE130CA (Taiwan Semiconductor Corporation, Tape & Reel packaging) offers active product status with identical electrical specifications and full compliance certifications. This option is suitable for high-volume production environments where tape and reel packaging provides handling and assembly advantages.

Both substitutes maintain the critical electrical parameters (111V standoff, 2.3A peak pulse, 400W power dissipation) and thermal operating range (-55°C to 175°C) required for general-purpose transient suppression. The minor variation in clamping voltage (179V versus 187.95V) does not affect functional compatibility in applications where the standoff voltage and peak current ratings are the primary design constraints.

Frequently Asked Questions (FAQ)

Q: Can P4KE130CA or P4KE130CA-B be used as direct replacements for P4KE130C-B?

A: Yes. Both substitute parts maintain identical reverse standoff voltage (111V), peak pulse current (2.3A), power dissipation (400W), operating temperature range (-55°C to 175°C), and package configuration (DO-204AL through-hole). These are the critical parameters that determine functional equivalence for TVS diode selection.

Q: What is the difference between P4KE130CA and P4KE130CA-B?

A: The primary differences are manufacturer and packaging format. P4KE130CA-B is manufactured by Littelfuse Inc. in bulk packaging, while P4KE130CA is manufactured by Taiwan Semiconductor Corporation in tape and reel packaging. Electrical specifications and compliance certifications are identical.

Q: Why does the clamping voltage differ between the main part and substitutes?

A: The P4KE130C-B specifies a maximum clamping voltage of 187.95V, while both substitutes specify 179V. Both values fall within acceptable operating parameters for general-purpose transient suppression where the 111V reverse standoff voltage is the primary design criterion. The clamping voltage variation does not affect circuit compatibility.

Q: Are all three parts RoHS compliant?

A: Yes. The P4KE130C-B, P4KE130CA, and P4KE130CA-B are all ROHS3 compliant. Additionally, P4KE130CA and P4KE130CA-B carry REACH Unaffected certification.

Q: What packaging options are available?

A: P4KE130C-B and P4KE130CA-B are supplied in bulk packaging. P4KE130CA is supplied in tape and reel (TR) format, which is standard for automated assembly processes.

Q: Is the DO-204AL package the same as DO-41?

A: Yes. DO-204AL and DO-41 are equivalent designations for the same through-hole axial package configuration used in all three parts.
