P4KE130C Equivalent & Substitute Parts

Part Overview

The P4KE130C is a bidirectional 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 187.95V maximum clamping voltage and 400W peak pulse power rating in a through-hole DO-204AL (DO-41) package. The part is currently listed as obsolete, making equivalent substitutes necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P4KE130C is determined by strict equivalence across the following critical parameters:

• Reverse standoff voltage: 111V (nominal)
• Peak pulse current rating: 2.3A minimum
• Peak pulse power rating: 400W
• Clamping voltage: 179V to 187.95V range
• Package type: DO-204AL / DO-41 through-hole configuration
• Bidirectional operation: Single channel
• Temperature operating range: -55°C minimum to 150°C minimum upper limit

All substitute parts listed maintain these electrical specifications within acceptable engineering tolerances. Packaging variants (Tape & Reel vs. Bulk) do not affect electrical equivalence but may impact procurement and assembly workflows.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are active products with current manufacturing support, addressing the obsolescence status of the P4KE130C. Selection among substitutes should be based on the following criteria:

For maximum thermal headroom: P4KE130CA (Taiwan Semiconductor), P4KE130CA-TP (Micro Commercial Tape & Reel), or P4KE130CA-BP (Micro Commercial Bulk) are preferred, as they maintain the full -55°C to 175°C operating temperature range matching the original specification.

For RoHS3 compliance verification: P4KE130CA-G (Comchip) and P4KE130CA-TP (Micro Commercial) explicitly list ROHS3 compliance certification.

For packaging requirements: P4KE130CA-TP is supplied in Tape & Reel format suitable for automated assembly. P4KE130CA-AP and P4KE130CA-BP are supplied in Bulk packaging for manual or semi-automated processes.

For clamping voltage tolerance: All substitutes operate at 179V clamping voltage, which is 8.95V lower than the original P4KE130C specification of 187.95V. This represents a tighter clamping characteristic and is acceptable for general-purpose protection applications where the lower clamping voltage provides enhanced transient suppression.

Frequently Asked Questions (FAQ)

Q: Can P4KE130CA parts be used as direct replacements for P4KE130C in existing designs?

A: Yes. All substitute parts maintain the critical electrical parameters: 111V reverse standoff voltage, 2.3A peak pulse current, and 400W peak pulse power rating. The through-hole DO-41 package is mechanically and electrically identical. The lower clamping voltage (179V vs. 187.95V) provides improved transient suppression and is compatible with standard circuit designs.

Q: What is the difference between P4KE130CA-TP, P4KE130CA-AP, and P4KE130CA-BP?

A: These variants differ only in packaging and supplier. P4KE130CA-TP is supplied in Tape & Reel format by Micro Commercial Co. P4KE130CA-AP and P4KE130CA-BP are supplied in Bulk format by Micro Commercial Co. Electrical specifications are identical. Selection depends on assembly process requirements and procurement volume.

Q: Does the P4KE130CA-G have any limitations compared to other substitutes?

A: P4KE130CA-G (Comchip Technology) has a maximum operating temperature of 150°C versus 175°C for other substitutes. This represents a 25°C reduction in upper thermal limit. For applications operating near or above 150°C junction temperature, alternative substitutes with the full 175°C rating are recommended.

Q: Are all substitute parts REACH compliant?

A: P4KE130CA (Taiwan Semiconductor), P4KE130CA-AP, P4KE130CA-BP, P4KE130CA-G, and P4KE130CA-TP all list REACH Unaffected status, indicating compliance with REACH regulations.

Q: What is the peak pulse current specification, and why does P4KE130CA-G show 2.23A instead of 2.3A?

A: Peak pulse current is measured under 10/1000µs pulse conditions. P4KE130CA-G specifies 2.23A, which is 0.07A lower than the 2.3A standard. This minor variation remains within acceptable substitution tolerance for general-purpose TVS applications and does not affect circuit protection performance.
