P6KE180A-TP Equivalent & Substitute Parts

Part Overview

The P6KE180A-TP is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose transient voltage protection in through-hole applications. This component features a 154V reverse standoff voltage with 246V maximum clamping voltage and 2.4A peak pulse current capability. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Equivalent and substitute parts are identified based on matching electrical characteristics and mechanical compatibility within the DO-15 package family.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6KE180A-TP are qualified based on the following critical parameters that determine functional equivalence:

• Voltage - Reverse Standoff (Typ): 154V
• Voltage - Clamping (Max) @ Ipp: 246V
• Current - Peak Pulse (10/1000µs): 2.4A minimum
• Power - Peak Pulse: 600W
• Package / Case: DO-15 or DO-204AC (axial through-hole)
• Type: Zener unidirectional TVS diode
• Mounting Type: Through Hole

Substitute parts must maintain identical voltage ratings and support equivalent or higher peak pulse current ratings. Package compatibility is limited to DO-15 and DO-204AC variants. All substitutes must be active production status with appropriate compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts listed maintain active production status with identical voltage and power specifications. The P6KE180A-TP (Micro Commercial Co) and P6KE180A-E3/54 (Vishay) both specify the full operating temperature range of -55°C to 175°C and carry ROHS3 compliance certification. The P6KE180A from Fairchild Semiconductor operates within a narrower temperature range (-50°C to 175°C) and does not specify RoHS compliance status in the provided data.

For applications requiring the full -55°C lower temperature limit and confirmed RoHS3 compliance, the P6KE180A-E3/54 (Vishay TransZorb® series) is the primary substitute. The Fairchild P6KE180A is suitable for applications where the -50°C minimum temperature is acceptable and RoHS compliance is not a requirement. All parts share identical voltage ratings, package compatibility, and through-hole mounting configuration.

Frequently Asked Questions (FAQ)

Q: Can P6KE180A from Fairchild Semiconductor replace P6KE180A-TP in all applications?

A: The Fairchild part is electrically compatible with matching voltage and power ratings. However, it specifies a minimum operating temperature of -50°C versus -55°C for the original part. Substitution is valid only if your application does not require operation below -50°C. RoHS compliance status is not specified for the Fairchild variant.

Q: What is the difference between P6KE180A and P6KE180A-E3/54?

A: Both parts are functionally equivalent with identical voltage ratings (154V standoff, 246V clamping) and power specifications (600W peak pulse). The P6KE180A-E3/54 is the Vishay TransZorb® series variant with confirmed ROHS3 compliance and full -55°C to 175°C operating range. The base P6KE180A designation may refer to multiple manufacturer variants.

Q: Are all substitute parts compatible with DO-15 package footprints?

A: Yes. All listed parts use DO-15 or DO-204AC package designations, which are mechanically and electrically compatible axial through-hole packages. PCB footprints designed for DO-15 will accommodate all listed substitutes without modification.

Q: Which substitute part has the highest peak pulse current rating?

A: The P6KE180A from Fairchild Semiconductor is rated for 2.5A peak pulse current, compared to 2.4A for both the original P6KE180A-TP and the Vishay P6KE180A-E3/54. This provides additional margin in transient protection capability.

Q: What compliance certifications apply to all substitute parts?

A: All parts carry EAR99 export classification and HTSUS code 8541.10.0080. The P6KE180A-TP and P6KE180A-E3/54 are ROHS3 compliant with MSL rating of 1 (Unlimited). RoHS compliance is not specified for the Fairchild P6KE180A variant in the provided data.
