3KP36A-TP Transient Voltage Suppressor Diode - Equivalent & Substitute Parts

Part Overview

The 3KP36A-TP is an active Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection applications. This unidirectional Zener diode features a 36V reverse standoff voltage with a 58.1V maximum clamping voltage and 3000W peak pulse power rating. The device is packaged in R-6 axial configuration and is ROHS3 compliant with unlimited moisture sensitivity rating. Equivalent and substitute parts are identified based on matching electrical parameters and mechanical compatibility within the TVS diode category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3KP36A-TP are qualified based on the following critical parameters:

• Voltage - Reverse Standoff: 36V (exact match required)
• Voltage - Breakdown (Min): 40V or higher (acceptable range)
• Voltage - Clamping (Max) @ Ipp: 58.1V to 61.8V (acceptable range for overvoltage protection)
• Unidirectional Channels: 1 (single channel requirement)
• Mounting Type: Through Hole (mechanical compatibility)
• Operating Temperature Range: -55°C minimum to 175°C maximum (thermal compatibility)
• Type: Zener (functional equivalence)
• RoHS Status: ROHS3 Compliant (regulatory compliance)

Substitute parts are grouped by power rating capability: 5kW, 15kW, and 30kW variants. All qualified substitutes maintain the 36V standoff voltage specification and are suitable for general-purpose transient voltage suppression applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the original 3KP36A-TP specification. Selection among substitutes depends on application power dissipation requirements:

The 5KP36A and 5KP36A-E3/54 provide equivalent electrical performance with increased power handling (5kW versus 3kW). The 5KP36A-E3/54 maintains the full operating temperature range of the original part (-55°C to 175°C), while the 5KP36A operates from -50°C minimum. Both 5kW variants use P600 axial packaging, which differs mechanically from the original R-6 package.

The 15KPA36A and 30KPA36A offer higher power dissipation capability (15kW and 30kW respectively) for applications requiring enhanced transient suppression. These parts maintain the -55°C to 175°C operating range and P600 axial packaging. Clamping voltages remain within acceptable tolerance (59.8V and 61.8V respectively).

Frequently Asked Questions (FAQ)

Q: Can the 5KP36A directly replace the 3KP36A-TP?

A: Electrical substitution is valid based on matching 36V standoff voltage, 40V breakdown voltage, and 58.1V clamping voltage. Mechanical substitution requires board layout accommodation for P600 axial package versus R-6 package. The 5KP36A operates from -50°C minimum, which may not meet applications requiring -55°C operation.

Q: What is the difference between 5KP36A and 5KP36A-E3/54?

A: Both parts share identical electrical specifications (36V standoff, 58.1V clamping, 5kW power rating, 86A peak current). The 5KP36A-E3/54 maintains the full -55°C to 175°C operating temperature range, while the 5KP36A operates from -50°C. The 5KP36A-E3/54 is packaged in Cut Tape (CT) format versus Tape & Reel (TR) for the 5KP36A.

Q: When should the 15KPA36A or 30KPA36A be selected?

A: These higher-power variants (15kW and 30kW) are selected when application transient energy exceeds the 3kW or 5kW capability of lower-rated devices. All three maintain 36V standoff voltage and general-purpose application suitability. Peak pulse current increases proportionally with power rating.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the regulatory status of the original 3KP36A-TP.

Q: What packaging considerations apply to substitution?

A: The original 3KP36A-TP uses R-6 axial package. All substitute parts use P600 axial package. Both are through-hole mounted, but board layout and component spacing must accommodate the different package dimensions. Verify PCB footprint compatibility before substitution.
