P6KE13C-B Equivalent & Substitute Parts

Part Overview

The P6KE13C-B is a transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This component features a 11.1V reverse standoff voltage with a 19.11V maximum clamping voltage and 600W peak pulse power rating in a through-hole DO-204AC (DO-15) axial package.

The P6KE13C-B is classified as obsolete. Substitute parts are necessary to maintain design continuity and ensure ongoing component availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6KE13C-B is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Voltage - Reverse Standoff (Typ): 11.1V (primary protection threshold)
• Voltage - Clamping (Max) @ Ipp: Must not exceed 19.11V to maintain circuit protection integrity
• Power - Peak Pulse: 600W minimum rating
• Type: Zener diode configuration

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole
• Package / Case: DO-204AC (DO-15) Axial configuration
• Bidirectional Channels: 1

Regulatory Compliance:

• RoHS3 Compliance required
• ECCN: EAR99
• HTSUS: 8541.10.0080

The substitute parts P6KE13CA-B and P6KE13CA meet these criteria with equivalent standoff voltage (11.1V), reduced clamping voltage (18.2V), and identical power rating (600W), while maintaining the same package and through-hole mounting configuration.

Parameter Comparison

Engineering Selection Recommendations

P6KE13CA-B (Littelfuse Inc.) is the primary substitute for the obsolete P6KE13C-B. Both components are manufactured by Littelfuse Inc., share identical reverse standoff voltage (11.1V), and maintain ROHS3 compliance. The P6KE13CA-B is currently in active production status with 661 units in stock. The reduced clamping voltage (18.2V vs. 19.11V) provides improved transient suppression performance while remaining within acceptable circuit protection parameters. Operating temperature range matches the original specification (-55°C ~ 175°C).

P6KE13CA (Fairchild Semiconductor) serves as a secondary substitute option. This component maintains electrical equivalence with identical reverse standoff voltage (11.1V) and power rating (600W), with marginally improved peak pulse current capability (34A vs. 34.6A). The operating temperature range is slightly reduced (-50°C ~ 175°C vs. -55°C ~ 175°C). This part is suitable for applications where the lower temperature minimum is acceptable. Availability is higher with 17,207 units in stock.

Both substitute parts are qualified for general-purpose transient voltage suppression applications and maintain mechanical compatibility with existing through-hole PCB designs.

Frequently Asked Questions (FAQ)

Q: Can P6KE13CA-B and P6KE13CA be used interchangeably with P6KE13C-B?

A: Yes, both substitute parts meet the electrical and mechanical requirements for direct replacement. The P6KE13CA-B is the preferred choice due to identical manufacturer and operating temperature range. The P6KE13CA is suitable where the -50°C minimum operating temperature is acceptable.

Q: What is the significance of the reduced clamping voltage in the substitute parts?

A: The substitute parts feature a maximum clamping voltage of 18.2V compared to the original 19.11V. This represents improved transient suppression performance, as the lower clamping voltage provides faster voltage regulation during overvoltage events while maintaining the same 11.1V reverse standoff threshold.

Q: Are the substitute parts available in the same package configuration?

A: Yes, both P6KE13CA-B and P6KE13CA are supplied in the DO-204AC (DO-15) axial through-hole package, identical to the original P6KE13C-B. No PCB layout modifications are required.

Q: What is the difference between P6KE13CA-B and P6KE13CA?

A: The primary differences are manufacturer (Littelfuse vs. Fairchild Semiconductor), packaging designation (Bulk for both), and operating temperature minimum (-55°C vs. -50°C). Electrical performance is equivalent. Peak pulse current is marginally higher in the Fairchild part (34A vs. 34.6A).

Q: Is RoHS3 compliance maintained with the substitute parts?

A: P6KE13CA-B maintains full ROHS3 compliance. RoHS status for P6KE13CA is not specified in available documentation. For applications requiring certified RoHS3 compliance, P6KE13CA-B is the recommended choice.

Q: What inventory levels are available for these substitute parts?

A: P6KE13CA-B has 661 units in stock. P6KE13CA has 17,207 units in stock. Both parts are currently in active production.
