30KP75CA-TP Equivalent & Substitute Parts

Part Overview

The 30KP75CA-TP is a Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose transient voltage protection applications. This through-hole axial component operates across a temperature range of -55°C to 175°C and is ROHS3 compliant with unlimited moisture sensitivity rating. The part is currently in active production status with 1074 units available in stock.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the critical voltage and power parameters that define TVS diode functionality in circuit protection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 30KP75CA-TP is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 75V
• Voltage - Breakdown (Min): 83.8V minimum
• Voltage - Clamping (Max) @ Ipp: within acceptable range for 30kW class
• Power - Peak Pulse: 30000W (30kW) or lower-rated alternatives for reduced transient energy
• Mounting Type: Through Hole
• Package / Case: Axial configuration
• Operating Temperature: -55°C to 175°C minimum
• Type: Zener diode, bidirectional, single channel

Three substitute parts meet these criteria with variations in power rating and packaging format. The 30KPA75CA maintains identical electrical specifications with alternative packaging. The 15KPA75CA provides reduced power handling (15kW) suitable for lower-energy transient environments. The 5KP75CA offers the lowest power rating (5kW) with compatible voltage parameters.

Parameter Comparison

Engineering Selection Recommendations

All four parts maintain active production status and ROHS3 compliance, ensuring regulatory alignment for new designs and ongoing supply chain availability.

The 30KPA75CA provides direct electrical equivalence to the 30KP75CA-TP with identical voltage and power specifications. This substitute is suitable for applications where the R-6 package footprint can be adapted to the P600 axial configuration.

The 15KPA75CA is applicable in transient protection circuits where peak pulse energy does not exceed 15kW. This part maintains voltage compatibility while reducing power dissipation requirements, making it suitable for lower-energy transient environments.

The 5KP75CA is applicable in circuits with transient energy below 5kW. This part is available from Diotec Semiconductor with equivalent voltage parameters and through-hole axial mounting. The operating temperature range extends to -50°C minimum, which is acceptable for applications not requiring -55°C operation.

All substitute parts are available in active inventory with quantities ranging from 1074 to 4032 units.

Frequently Asked Questions (FAQ)

Q: Can the 30KPA75CA directly replace the 30KP75CA-TP?

A: The 30KPA75CA maintains identical voltage specifications (75V standoff, 83.8V breakdown minimum, 119.4V clamping maximum) and power rating (30kW). The primary difference is the package designation (P600 versus R-6). Both are axial through-hole configurations suitable for PCB mounting. Mechanical compatibility depends on the specific PCB footprint design.

Q: What is the difference between the 30KP75CA-TP and the 15KPA75CA?

A: Both parts share the same 75V reverse standoff voltage and similar clamping voltages (119.4V versus 122V). The primary difference is power handling: the 30KP75CA-TP is rated for 30kW peak pulse power, while the 15KPA75CA is rated for 15kW. The 15KPA75CA is suitable for applications with lower transient energy requirements.

Q: Is the 5KP75CA suitable for all applications using the 30KP75CA-TP?

A: The 5KP75CA maintains the 75V voltage class and compatible clamping voltage (121V). However, its 5kW power rating is significantly lower than the 30kW rating of the main part. The 5KP75CA is suitable only for circuits where peak transient pulse energy does not exceed 5kW. The operating temperature minimum is -50°C rather than -55°C.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The 30KPA75CA, 15KPA75CA, and 5KP75CA are all ROHS3 compliant, matching the regulatory status of the 30KP75CA-TP.

Q: What packaging formats are available among the substitute parts?

A: The 30KP75CA-TP is supplied in Tape & Reel (TR) format. The 30KPA75CA and 15KPA75CA are supplied in Bulk packaging. The 5KP75CA is supplied in Tape & Reel (TR) format. All parts use axial through-hole mounting with P600 or R-6 package designations.
