30KP75A-TP Equivalent & Substitute Parts

Part Overview

The 30KP75A-TP is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose transient voltage protection applications. This through-hole component features a 75V reverse standoff voltage with a 119.4V maximum clamping voltage and 30kW peak pulse power rating. The part is ROHS3 compliant and currently in active production status with 810 units available in stock.

Substitute parts are identified when equivalent electrical performance can be achieved within the allowed parameter tolerances for this TVS diode category, particularly when the main part becomes unavailable or when alternative packaging or supplier options are required for procurement flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 30KP75A-TP are qualified based on the following critical electrical parameters that must remain within acceptable tolerances:

• Voltage - Reverse Standoff: 75V (exact match required)
• Voltage - Breakdown (Min): 83.3V to 83.8V range
• Voltage - Clamping (Max) @ Ipp: 119.4V to 122V range
• Unidirectional Channels: 1 (single channel configuration)
• Operating Temperature: -55°C ~ 175°C (TJ) minimum requirement
• Mounting Type: Through Hole (axial package orientation)
• Type: Zener diode construction
• Applications: General Purpose

The three identified substitute parts (5KP75A, 5KP75A-E3/54, and 15KPA75A) meet these core electrical specifications. Differences in peak pulse power rating (5kW, 5kW, and 15kW respectively) represent lower power-handling capability compared to the 30KP75A-TP, making these suitable for applications with reduced transient energy requirements. All substitute parts maintain identical voltage characteristics and thermal operating ranges.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active production status and ROHS3 compliance, ensuring regulatory alignment with the 30KP75A-TP. Selection between substitute options depends on application-specific peak pulse power requirements:

For applications requiring 30kW peak pulse power handling, the 30KP75A-TP remains the only qualified option among the listed parts.

For applications tolerating 15kW peak pulse power, the 15KPA75A provides the highest power rating among substitutes while maintaining identical voltage specifications. This part is available in bulk packaging from MDE Semiconductor Inc.

For applications requiring 5kW peak pulse power, both the 5KP75A (Littelfuse Inc., Cut Tape packaging) and 5KP75A-E3/54 (Vishay TransZorb® series, Cut Tape packaging) are functionally equivalent. The Vishay part carries the TransZorb® brand designation and represents an established industrial standard for TVS protection.

Package differences exist between the main part (R-6 case) and all substitutes (P600 case), requiring mechanical verification for board layout compatibility despite identical axial through-hole mounting orientation.

Frequently Asked Questions (FAQ)

Q: Can the 5KP75A or 5KP75A-E3/54 directly replace the 30KP75A-TP?

A: These parts are electrically compatible for voltage protection function but have reduced peak pulse power ratings (5kW versus 30kW). Direct substitution is valid only when the application transient energy does not exceed 5kW. The R-6 and P600 package cases differ mechanically, requiring board layout verification.

Q: What is the difference between the 5KP75A and 5KP75A-E3/54?

A: Both parts share identical electrical specifications (75V standoff, 121V clamping, 5kW power rating) and operating temperature range. The 5KP75A-E3/54 is manufactured by Vishay under the TransZorb® product line, while the 5KP75A is manufactured by Littelfuse Inc. Both are ROHS3 compliant and in active production.

Q: Why is the 15KPA75A listed as a substitute if it has lower power than the 30KP75A-TP?

A: The 15KPA75A qualifies as a substitute based on matching voltage specifications (75V standoff, 122V clamping) and thermal operating range. While its 15kW power rating is lower than the 30kW main part, it provides intermediate power handling for applications exceeding 5kW but not requiring the full 30kW capability.

Q: Are all substitute parts available in the same packaging as the 30KP75A-TP?

A: No. The 30KP75A-TP uses R-6 axial packaging, while all three substitute parts use P600 axial packaging. Both are through-hole axial configurations, but physical dimensions differ. Verify board layout compatibility before substitution.

Q: Do all parts meet the same compliance standards?

A: Yes. The 30KP75A-TP and all three substitute parts are ROHS3 compliant, EAR99 classified, and carry HTSUS code 8541.10.0080. All are rated for -55°C to 175°C operating temperature and feature Moisture Sensitivity Level 1 (unlimited shelf life).
