5KP85A-TP Transient Voltage Suppressor Equivalent & Substitute Parts

Part Overview

The 5KP85A-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 operates with an 85V reverse standoff voltage and provides 5000W peak pulse power dissipation in an R-6 axial through-hole package. The part is ROHS3 compliant and carries an unlimited moisture sensitivity level rating, making it suitable for standard industrial and commercial electronic protection circuits.

Equivalent and substitute parts are necessary when the original 5KP85A-TP becomes unavailable, when alternative packaging formats are required, or when higher power dissipation capabilities are needed for enhanced circuit protection margins.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5KP85A-TP is determined by the following critical parameters:

• Voltage - Reverse Standoff: Must be 85V (±tolerance as per manufacturer specifications)
• Voltage - Clamping (Max) @ Ipp: Must be within 137V ±tolerance range
• Type: Must be Zener diode
• Unidirectional Channels: Must be 1 channel
• Mounting Type: Must be Through Hole
• Applications: General Purpose protection

The substitute parts listed below meet these core electrical and mechanical requirements. Variations in peak pulse power rating, peak pulse current, and package case format are permitted when the primary voltage protection parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

All three parts listed maintain active product status and ROHS3 compliance, confirming their suitability for current design implementations.

The 5KP85A from Diotec Semiconductor provides direct electrical equivalence to the 5KP85A-TP with identical power dissipation (5000W) and clamping voltage (137V). This part is recommended when package case format P600 is acceptable as an alternative to R-6.

The 15KPA85A from MDE Semiconductor Inc maintains equivalent voltage protection parameters while offering enhanced power dissipation capability (15000W versus 5kW). This part is suitable for applications requiring higher transient energy absorption margins. The P600 package case applies to this substitute as well.

Package case differences (R-6 versus P600) represent the primary mechanical variation among these parts. Both are axial through-hole formats compatible with standard PCB mounting practices. Verify PCB layout and footprint compatibility before final selection.

Frequently Asked Questions (FAQ)

Q: Can the 15KPA85A be used as a direct replacement for the 5KP85A-TP?

A: Yes. The 15KPA85A meets all core electrical requirements: 85V reverse standoff voltage, 137.6V clamping voltage, and unidirectional Zener diode configuration. The higher power rating (15kW versus 5kW) provides additional protection margin. Package case differs (P600 versus R-6), requiring PCB footprint verification.

Q: What is the difference between the R-6 and P600 package cases?

A: Both are axial through-hole packages for through-hole PCB mounting. R-6 and P600 represent different physical form factors from different manufacturers. Verify your PCB layout accommodates the selected package dimensions before procurement.

Q: Are all three parts ROHS3 compliant?

A: Yes. The 5KP85A-TP, 15KPA85A, and 5KP85A from Diotec all carry ROHS3 compliance certification.

Q: What is the operating temperature range difference between these parts?

A: The 5KP85A-TP and 15KPA85A operate from -55°C to 175°C. The Diotec 5KP85A operates from -50°C to 175°C. For applications requiring -55°C minimum operation, select either the 5KP85A-TP or 15KPA85A.

Q: Can I use the 5KP85A from Diotec as a direct replacement?

A: Yes. The Diotec 5KP85A provides electrical equivalence with identical voltage parameters and power dissipation. The primary difference is package case format (P600 versus R-6). Confirm PCB compatibility before substitution.

Q: Why would I choose the higher power 15KPA85A over the standard 5kW parts?

A: The 15KPA85A accommodates higher transient energy events without exceeding thermal limits. Select this part when circuit analysis indicates peak pulse currents or energy levels approaching the 5kW rating of standard parts.
