30KP90A-TP Transient Voltage Suppressor Equivalent & Substitute Parts

Part Overview

The 30KP90A-TP is a unidirectional Zener-type transient voltage suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection in through-hole applications. This component features a 90V reverse standoff voltage with a 146.4V maximum clamping voltage and 30kW peak pulse power rating. The part is actively produced, RoHS3 compliant, and available in R-6 axial packaging with unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are identified based on matching electrical parameters within the 90V voltage class and compatible through-hole mounting configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 30KP90A-TP are qualified based on the following electrical and mechanical criteria:

• Voltage - Reverse Standoff: 90V (exact match required)
• Voltage - Breakdown (Min): 100V to 100.5V range
• Voltage - Clamping (Max) @ Ipp: 145.6V to 146.4V range
• Type: Zener, unidirectional configuration
• Mounting Type: Through Hole, axial package
• Operating Temperature: -55°C ~ 175°C (TJ)
• RoHS3 Compliance: Required
• Product Status: Active

Substitutes are grouped by power rating capability. The 30KP90A-TP (30kW) represents the highest power class in this voltage family. Lower-power alternatives (5kW and 15kW) are listed as substitutes where system design permits reduced peak pulse power handling.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and RoHS3 compliance, ensuring regulatory continuity and supply chain viability. Selection among substitutes depends on system peak pulse power requirements:

The 30KP90A-TP is specified for applications requiring the full 30kW peak pulse power rating. The 15KPA90A provides 15kW capability and represents a mid-range alternative. The 5KP90A and 5KP90A-E3/54 are suitable only for applications with peak pulse power requirements not exceeding 5kW.

All parts share identical reverse standoff voltage (90V), breakdown voltage range (100V–100.5V), and clamping voltage range (145.6V–146.4V), ensuring equivalent transient suppression performance within the specified voltage class. Operating temperature ranges are identical across all variants.

Package differences exist: the 30KP90A-TP uses R-6 axial packaging, while substitute parts use P600 axial packaging. Physical dimensions and PCB footprints differ accordingly and must be verified for mechanical compatibility in the target application.

Frequently Asked Questions (FAQ)

Q: Can the 5KP90A or 5KP90A-E3/54 be used as direct replacements for the 30KP90A-TP?

A: Electrical substitution is possible only if the application's peak pulse power requirement does not exceed 5kW. The 5kW-rated parts will not safely handle transient events requiring 30kW dissipation. Additionally, the P600 package differs from the R-6 package, requiring PCB layout verification.

Q: What is the difference between the 5KP90A and 5KP90A-E3/54?

A: Both parts are 5kW-rated TVS diodes with 90V standoff voltage and nearly identical clamping characteristics (146V vs. 146V). The primary difference is manufacturer: 5KP90A is supplied by Littelfuse Inc., while 5KP90A-E3/54 is supplied by Vishay General Semiconductor. Peak pulse current differs slightly (34.9A vs. 34.2A), but both meet the same electrical specifications for the 90V class.

Q: Is the 15KPA90A suitable for applications currently using the 30KP90A-TP?

A: The 15KPA90A is suitable only if the application's peak pulse power requirement is between 5kW and 15kW. If the design requires the full 30kW capability, the 15KPA90A will not provide adequate transient suppression margin. Voltage and temperature specifications are identical.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The 30KP90A-TP, 15KPA90A, 5KP90A, and 5KP90A-E3/54 are all RoHS3 compliant, ensuring regulatory compliance across all substitution options.

Q: Do package differences affect electrical performance?

A: Package differences (R-6 vs. P600) do not affect electrical performance but impact physical dimensions, lead spacing, and PCB footprint. Mechanical compatibility must be verified before substitution. Both are through-hole axial packages suitable for wave soldering and manual assembly.

Q: What is the REACH status of these parts?

A: The 30KP90A-TP, 5KP90A, and 5KP90A-E3/54 are REACH Unaffected. The 15KPA90A has REACH information available upon request from the manufacturer.
