15KP30A-TP Transient Voltage Suppressor Diode - Equivalent & Substitute Parts

Part Overview

The 15KP30A-TP is an active-status unidirectional 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. Substitute parts are identified based on matching core electrical parameters: 30V reverse standoff voltage, 33V+ breakdown voltage minimum, 50.7V maximum clamping voltage at peak pulse current, and 15kW peak pulse power rating within the through-hole axial package category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 15KP30A-TP is determined by the following mandatory parameters:

• Voltage - Reverse Standoff (Typ): 30V
• Voltage - Breakdown (Min): 33V or greater
• Voltage - Clamping (Max) @ Ipp: 50.7V or less
• Power - Peak Pulse: 15000W (15kW) or greater
• Unidirectional Channels: 1
• Mounting Type: Through Hole
• Package Category: Axial

Parts meeting these criteria are classified as direct substitutes. Parts exceeding the clamping voltage or power rating remain functionally compatible for general-purpose transient protection but operate with different performance characteristics. All identified substitutes maintain the 30V standoff voltage specification and unidirectional topology required for equivalent circuit protection.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and ROHS3 compliance, meeting regulatory requirements equivalent to the 15KP30A-TP.

The 15KPA30A (Good-Ark Semiconductor) provides direct electrical equivalence with matching 30V standoff, 50.7V clamping voltage, and 15kW power rating. Operating temperature range is limited to -55°C to 150°C compared to the main part's -55°C to 175°C specification.

The 30KPA30A (MDE Semiconductor Inc) maintains 30V standoff voltage and exceeds power handling capability at 30kW with 55.2V clamping voltage. This part operates across the full -55°C to 175°C temperature range. Higher clamping voltage and power rating result in different transient response characteristics.

The 5KP30A (Diotec Semiconductor) and 5KP30A-E3/54 (Vishay General Semiconductor) both provide 30V standoff voltage with reduced power rating of 5kW and lower clamping voltage of 48.4V. These parts are suitable for applications requiring lower transient energy dissipation. The Vishay part includes TransZorb® series designation and operates across -55°C to 175°C.

Frequently Asked Questions (FAQ)

Q: Can the 15KPA30A replace the 15KP30A-TP in all applications?

A: The 15KPA30A matches the electrical specifications (30V standoff, 50.7V clamping, 15kW power) but operates to a maximum temperature of 150°C versus 175°C for the main part. Selection depends on application temperature requirements.

Q: What is the difference between the 5KP30A variants and the 15KP30A-TP?

A: The 5KP30A and 5KP30A-E3/54 are rated for 5kW peak pulse power compared to 15kW for the main part. Both maintain 30V standoff voltage but with lower clamping voltage (48.4V). These parts are suitable for lower-energy transient protection applications.

Q: Why does the 30KPA30A have a higher clamping voltage (55.2V) than the main part (50.7V)?

A: The 30KPA30A is rated for 30kW peak pulse power, double the 15kW rating of the main part. Higher clamping voltage is associated with the increased power dissipation capability. This part is suitable for applications requiring greater transient energy absorption.

Q: Are all substitute parts available in the same package as the 15KP30A-TP?

A: The main part uses R-6 axial package. Substitute parts use P600 axial package. Both are through-hole axial configurations suitable for PCB mounting, though physical dimensions may differ. Verify PCB layout compatibility before substitution.

Q: Do all parts meet the same compliance standards?

A: All identified parts are ROHS3 compliant and active-status products. Moisture sensitivity level is 1 (Unlimited) for the main part and most substitutes, ensuring equivalent handling requirements during assembly and storage.
