P6KE12CA-E3/54 Equivalent & Substitute Parts

Part Overview

The P6KE12CA-E3/54 is a transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This bidirectional Zener diode is designed for general-purpose transient voltage suppression in through-hole applications using the DO-204AC (DO-15) package. The device is active and in production, with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P6KE12CA-E3/54 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Voltage - Reverse Standoff (Typ): 10.2V
• Voltage - Breakdown (Min): 11.4V
• Voltage - Clamping (Max) @ Ipp: 16.7V
• Current - Peak Pulse (10/1000µs): minimum 25A
• Power - Peak Pulse: minimum 400W
• Mounting Type: Through Hole
• Package / Case: DO-204AC (DO-15) or DO-204AL (DO-41) axial configurations
• Type: Zener, Bidirectional, single channel
• RoHS Status: ROHS3 Compliant

The P4KE12CA represents a lower-current alternative (25A vs. 35.9A peak pulse) with reduced peak pulse power (400W vs. 600W) but maintains identical voltage specifications and operates within the same temperature range. The P6KE12CA variants from Taiwan Semiconductor Corporation and Littelfuse Inc. provide direct electrical equivalence with peak pulse currents of 36A to 36.5A and 600W power ratings, matching or exceeding the original specification.

Parameter Comparison

Engineering Selection Recommendations

P6KE12CA (Taiwan Semiconductor Corporation) and P6KE12CA-B (Littelfuse Inc.) are the primary substitutes for the P6KE12CA-E3/54. Both maintain identical voltage specifications (10.2V standoff, 11.4V breakdown, 16.7V clamping) and equivalent peak pulse current ratings (36A and 36.5A respectively). All three parts are ROHS3 compliant with unlimited moisture sensitivity. The P6KE12CA variants are available in higher inventory quantities (25610 Pcs and 22100 Pcs) and support the same through-hole mounting configuration.

P4KE12CA (Taiwan Semiconductor Corporation) is a secondary substitute suitable only when peak pulse current requirements can be reduced to 25A and peak pulse power to 400W. This part maintains voltage equivalence but operates at reduced power capacity. The P4KE12CA uses the DO-204AL (DO-41) package, which differs from the DO-204AC (DO-15) package of the primary part, requiring PCB layout verification for mechanical compatibility.

All substitute parts carry active product status and ROHS3 compliance, ensuring regulatory alignment with the original specification.

Frequently Asked Questions (FAQ)

Q: Can P4KE12CA replace P6KE12CA-E3/54 in all applications?

A: No. The P4KE12CA has reduced peak pulse current (25A vs. 35.9A) and power rating (400W vs. 600W). It is suitable only for applications where transient energy levels do not exceed 400W. Additionally, the P4KE12CA uses the DO-204AL (DO-41) package, which has different physical dimensions than the DO-204AC (DO-15) package of the original part. PCB layout compatibility must be verified before substitution.

Q: What is the difference between P6KE12CA and P6KE12CA-B?

A: Both parts maintain identical voltage specifications and equivalent peak pulse current ratings (36A vs. 36.5A). The primary differences are manufacturer (Taiwan Semiconductor Corporation vs. Littelfuse Inc.) and packaging format (Cut Tape vs. Bulk). Both use the DO-204AC (DO-15) package and are ROHS3 compliant. Selection between these two is based on inventory availability and procurement preferences.

Q: Are all substitute parts pin-compatible with the original P6KE12CA-E3/54?

A: The P6KE12CA (Taiwan Semi) and P6KE12CA-B (Littelfuse) are pin-compatible, as both use the DO-204AC (DO-15) axial package. The P4KE12CA uses the DO-204AL (DO-41) package, which has the same pin count but different physical dimensions. Mechanical fit on the PCB must be verified for the P4KE12CA before substitution.

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

A: Yes. All substitute parts listed are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), matching the compliance profile of the P6KE12CA-E3/54. All parts carry EAR99 ECCN classification and HTSUS code 8541.10.0080.

Q: What is the operating temperature range for the substitute parts?

A: The P6KE12CA-E3/54 (Vishay), P4KE12CA (Taiwan Semi), and P6KE12CA-B (Littelfuse) all operate across -55°C to 175°C (TJ). The P6KE12CA from Taiwan Semiconductor Corporation does not specify an operating temperature range in the provided data.
