30KP150A-TP Transient Voltage Suppressor Diode - Equivalent & Substitute Parts

Part Overview

The 30KP150A-TP is an active Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection applications. This unidirectional Zener-type device operates through a 150V reverse standoff voltage with a 233.4V maximum clamping voltage and 30kW peak pulse power rating. The component is housed in an R-6 axial through-hole package and is ROHS3 compliant with unlimited moisture sensitivity rating. Substitute parts are necessary when the original part is unavailable, when alternative packaging formats are required, or when different power dissipation characteristics better suit specific circuit requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 30KP150A-TP is determined by the following critical electrical parameters: Voltage - Reverse Standoff (150V), Voltage - Breakdown minimum (167.6V range), and Unidirectional Zener type classification. All substitute parts listed maintain the 150V reverse standoff voltage specification, which is the primary functional requirement for circuit protection at this voltage level. Secondary considerations include clamping voltage performance, peak pulse power rating, and through-hole axial mounting compatibility. Substitute parts are grouped by their ability to meet or exceed the core voltage protection parameters while maintaining general-purpose application suitability and active product status.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, meeting regulatory requirements equivalent to the 30KP150A-TP. The 15KPA150A provides the closest power rating match at 15kW, suitable for applications where the full 30kW capability is not required. The 5KP150A and 5KP150A-E3/54 are appropriate for lower-power transient suppression scenarios, with the latter offering Vishay's TransZorb series designation. The BZW50-150 from STMicroelectronics maintains R-6 package compatibility with the main part but exhibits higher clamping voltage (343V) and should be selected only when higher clamping performance is acceptable for the circuit design. Package format differences (R-6 versus P600) must be verified against PCB layout constraints before final selection.

Frequently Asked Questions (FAQ)

Q: What is the primary substitution criterion for the 30KP150A-TP? A: The 150V reverse standoff voltage is the primary substitution criterion. All substitute parts maintain this specification to ensure equivalent overvoltage protection performance in the same voltage protection class.

Q: Can the 5KP150A replace the 30KP150A-TP in all applications? A: The 5KP150A is electrically compatible for voltage protection but has a reduced peak pulse power rating (5kW versus 30kW). Substitution is valid only when circuit transient energy levels do not exceed 5kW peak pulse power.

Q: What is the difference between R-6 and P600 packages? A: R-6 and P600 are both axial through-hole packages for TVS diodes. The primary difference is physical form factor and lead spacing. PCB layout compatibility must be verified before substitution between these package types.

Q: Is the BZW50-150 a direct substitute? A: The BZW50-150 maintains the 150V reverse standoff voltage and R-6 package compatibility but has a significantly higher clamping voltage (343V versus 233.4V). It is electrically compatible but may not be suitable for circuits designed around the lower clamping voltage of the original part.

Q: Are all substitute parts ROHS3 compliant? A: Yes, all listed substitute parts are ROHS3 compliant and meet the same regulatory requirements as the 30KP150A-TP.

Q: What operating temperature range should I expect from substitute parts? A: The 15KPA150A, 5KP150A, and 5KP150A-E3/54 all operate across -55°C to 175°C (TJ), matching the original part. The BZW50-150 does not specify an operating temperature range in the provided data.
