30KP64A-TP Equivalent & Substitute Parts

Part Overview

The 30KP64A-TP is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose transient voltage protection applications. This through-hole component features a 64V reverse standoff voltage with a 104V maximum clamping voltage and 30kW peak pulse power rating. The part is Active in product status and ROHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, manufacturing discontinuation, or design flexibility needs.

Substitute Part Grouping Explanation

Substitute parts for the 30KP64A-TP are grouped based on strict electrical and mechanical compatibility criteria. All substitute candidates maintain the following core parameters: 64V reverse standoff voltage, 71.5V minimum breakdown voltage, 104V maximum clamping voltage range, through-hole axial mounting, and operating temperature range of -55°C to 175°C. Substitution is valid when these parameters align within the specified tolerances. Power rating variations (30kW, 15kW, 5kW) and peak pulse current differences are secondary considerations that determine application suitability but do not disqualify substitution when electrical voltage characteristics match.

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and are suitable for general-purpose transient voltage suppression applications. The 30KPA64A provides direct electrical equivalence with identical 30kW power rating and is ROHS3 compliant. The 15KPA64A and 5KP64A series offer reduced power ratings (15kW and 5kW respectively) and are suitable for applications with lower transient energy requirements while maintaining voltage protection characteristics. The 5KP64A-E3/54 from Vishay provides ROHS3 compliance and is available in Cut Tape packaging. Selection should be based on application power requirements, packaging availability, and thermal design constraints. All candidates support the full -55°C to 175°C operating temperature range except the 5KP64A, which operates from -50°C.

Frequently Asked Questions (FAQ)

Q: Can the 30KPA64A directly replace the 30KP64A-TP? A: Yes. Both parts share identical voltage specifications (64V standoff, 71.5V breakdown, 104V clamping) and 30kW power rating. The primary difference is packaging format (R-6 versus P600 axial case) and supplier. Mechanical fit must be verified for the specific PCB layout.

Q: What is the difference between the 30KP64A-TP and the 5KP64A series? A: The primary difference is power rating. The 30KP64A-TP is rated for 30kW peak pulse power, while the 5KP64A series is rated for 5kW. Voltage protection characteristics (64V standoff, 104V clamping) are equivalent. The 5KP64A series is suitable only for applications with lower transient energy levels.

Q: Are package differences between R-6 and P600 significant for substitution? A: Yes. R-6 and P600 are different axial package geometries with different physical dimensions and lead spacing. PCB layout compatibility must be verified before substitution. Both are through-hole axial formats suitable for manual or automated assembly.

Q: Does the 5KP64A meet RoHS3 compliance? A: The 5KP64A from Diotec Semiconductor has RoHS status listed as "Not applicable." The 5KP64A-E3/54 from Vishay is ROHS3 compliant. Compliance requirements should be verified against project specifications.

Q: Can the 5KP64A-E3/54 be used in place of the 30KP64A-TP? A: Electrically, yes, for voltage protection. However, the 5KP64A-E3/54 is rated for 5kW peak pulse power compared to 30kW for the 30KP64A-TP. This substitution is valid only if the application transient energy does not exceed 5kW. Packaging is also different (P600 versus R-6).

Q: What is the operating temperature difference between parts? A: Most parts operate from -55°C to 175°C. The 5KP64A from Diotec operates from -50°C to 175°C, a 5°C reduction at the lower temperature limit. This may be significant for applications requiring full -55°C operation.

Q: Are all substitute parts available in the same packaging options? A: No. The 30KP64A-TP is supplied in Tape & Reel (TR) format. The 30KPA64A and 15KPA64A are supplied in Bulk. The 5KP64A packaging is not specified. The 5KP64A-E3/54 is supplied in Cut Tape (CT). Packaging availability should be confirmed with suppliers.
