30KP72A-TP Equivalent & Substitute Parts

Part Overview

The 30KP72A-TP is a unidirectional Zener transient voltage suppressor (TVS) diode designed for general-purpose overvoltage protection applications. Manufactured by Micro Commercial Co, this through-hole component operates across a wide temperature range of -55°C to 175°C and is ROHS3 compliant. The part is currently in active production status with 825 units available in stock. Alternative equivalent parts may be required due to packaging availability, supply chain considerations, or specific application requirements for different package configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 30KP72A-TP is determined by strict equivalence across the following critical electrical parameters:

• Voltage - Reverse Standoff (Typ): 72V
• Voltage - Breakdown (Min): 80.4V
• Voltage - Clamping (Max) @ Ipp: 114V
• Power - Peak Pulse: 30000W (30kW)
• Unidirectional Channels: 1
• Type: Zener
• Operating Temperature Range: -55°C ~ 175°C (TJ)
• Mounting Type: Through Hole

The 30KPA72A qualifies as an equivalent substitute based on matching all critical electrical specifications. Differences exist only in packaging format (P600 axial versus R-6 axial) and supplier device package designation, which do not affect electrical performance or functional compatibility in through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 30KP72A-TP and 30KPA72A are active production components with ROHS3 compliance and equivalent electrical specifications for 72V TVS diode applications. Selection between these parts should be based on:

• Packaging availability and PCB layout requirements (R-6 versus P600 axial packages)
• Supplier inventory and lead time considerations
• Existing design documentation and qualification history

The 30KPA72A offers higher inventory availability (2146 units in stock versus 825 units) and provides specified peak pulse current data (265.8A), which may be beneficial for detailed circuit analysis. Both components maintain identical voltage ratings, power dissipation capability, and operating temperature specifications required for general-purpose transient voltage suppression.

Frequently Asked Questions (FAQ)

Q: Can the 30KPA72A replace the 30KP72A-TP in existing designs?

A: Yes. Both components are unidirectional Zener TVS diodes with identical electrical specifications: 72V reverse standoff voltage, 80.4V minimum breakdown voltage, and 114V maximum clamping voltage at peak pulse current. The primary difference is the axial package designation (P600 versus R-6), which does not affect electrical performance in through-hole applications.

Q: What is the significance of the different package codes (R-6 versus P600)?

A: Both designations refer to axial through-hole packages suitable for PCB mounting. The package code difference reflects different supplier device package standards but does not alter the component's electrical characteristics or pin configuration. Physical dimensions and lead spacing should be verified against the respective datasheets for PCB layout compatibility.

Q: Are there any compliance or certification differences between these parts?

A: Both the 30KP72A-TP and 30KPA72A are ROHS3 compliant and carry EAR99 ECCN classification. The 30KPA72A lists REACH status as "info available upon request," while the 30KP72A-TP indicates REACH Unaffected status. Both components have MSL rating of 1 (Unlimited).

Q: Which part should be selected for new designs?

A: Selection should be based on supply chain availability, packaging preference, and existing supplier relationships. Both parts meet identical electrical requirements for 72V TVS diode applications. The 30KPA72A currently has higher inventory availability, which may reduce lead time for procurement.

Q: Is the peak pulse current specification (265.8A for 30KPA72A) critical for substitution?

A: The peak pulse current is a derived parameter from the power dissipation rating (30kW) and voltage specifications. Both parts are rated for 30kW peak pulse power, ensuring equivalent transient suppression capability. The specified current value for the 30KPA72A provides additional design documentation but does not establish a substitution limitation.
