P4KE13C-B Equivalent & Substitute Parts

Part Overview

The P4KE13C-B is a Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose transient voltage protection applications. This component features a 11.1V reverse standoff voltage with 19.11V maximum clamping voltage and 22.5A peak pulse current capability in a through-hole DO-204AL (DO-41) package format.

The P4KE13C-B is classified as obsolete. Equivalent and substitute parts are available from active product lines that maintain the same electrical and mechanical specifications, enabling continued system design and maintenance without redesign requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P4KE13C-B are qualified based on the following electrical and mechanical parameters:

• Reverse standoff voltage: 11.1V (identical)
• Package type: DO-204AL / DO-41 axial through-hole (identical)
• Zener diode type with single bidirectional channel (identical)
• Operating temperature range: -55°C ~ 175°C (identical)
• RoHS3 compliance and MSL rating (identical)
• Peak pulse power rating: 400W (identical)

Substitute parts maintain these core specifications while operating within acceptable tolerances for clamping voltage and peak pulse current as defined by the P4KE series electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both P4KE13CA and P4KE13CA-B are active product alternatives to the obsolete P4KE13C-B. Selection between these substitutes is based on product availability and packaging requirements:

P4KE13CA-B is the preferred substitute, manufactured by Littelfuse Inc., the original manufacturer of the P4KE13C-B. This part maintains identical peak pulse current specification (22.5A) and is available in bulk packaging. ROHS3 compliance and unlimited MSL rating are maintained.

P4KE13CA, manufactured by Taiwan Semiconductor Corporation, is an alternative substitute with active product status. This part offers slightly higher peak pulse current (23A) and is available in Tape & Reel packaging format. ROHS3 compliance and unlimited MSL rating are maintained.

Both substitutes operate within the same temperature range and maintain electrical compatibility for general-purpose transient voltage suppression applications.

Frequently Asked Questions (FAQ)

Q: Can P4KE13CA and P4KE13CA-B be used interchangeably with P4KE13C-B?

A: Both parts are electrical and mechanical equivalents. They share identical reverse standoff voltage (11.1V), operating temperature range (-55°C ~ 175°C), package type (DO-204AL / DO-41), and power rating (400W). Clamping voltage and peak pulse current specifications fall within acceptable P4KE series tolerances.

Q: What is the difference between P4KE13CA and P4KE13CA-B?

A: The primary differences are manufacturer and packaging format. P4KE13CA-B is manufactured by Littelfuse Inc. in bulk packaging, while P4KE13CA is manufactured by Taiwan Semiconductor Corporation in Tape & Reel format. Electrical specifications are equivalent with minor variations in peak pulse current (22.5A vs. 23A) and clamping voltage (18.2V for both).

Q: Why is the P4KE13C-B classified as obsolete?

A: The P4KE13C-B has been discontinued by the manufacturer. Active equivalent products (P4KE13CA and P4KE13CA-B) are available to support ongoing system requirements without design changes.

Q: Are there packaging considerations when substituting these parts?

A: Yes. P4KE13CA-B is supplied in bulk packaging, while P4KE13CA is supplied in Tape & Reel format. Both use identical through-hole DO-204AL (DO-41) axial package geometry, ensuring mechanical compatibility on PCBs. Packaging selection depends on assembly process requirements and order quantities.

Q: Do all three parts meet the same compliance standards?

A: Yes. P4KE13C-B, P4KE13CA, and P4KE13CA-B are all ROHS3 compliant with MSL rating of 1 (Unlimited). All parts carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications.
