30KPA78CE3/TR13 Equivalent & Substitute Parts

Part Overview

The 30KPA78CE3/TR13 is a transient voltage suppressor (TVS) diode manufactured by Microchip Technology, classified as a Zener-type bidirectional TVS device in P600 axial through-hole packaging. This component is designed for general-purpose transient voltage suppression applications with a reverse standoff voltage of 78V and peak pulse power rating of 30kW. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified based on matching or compatible electrical and mechanical parameters, including reverse standoff voltage, breakdown voltage, clamping characteristics, peak pulse power rating, package type, and operating temperature range. Substitutes enable component selection flexibility when the primary part is unavailable or when alternative manufacturers' specifications align with application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 30KPA78CE3/TR13 are qualified based on the following critical parameters:

Matching Criteria:

• Reverse standoff voltage: 78V (nominal)
• Breakdown voltage range: 82.13V minimum or higher
• Bidirectional Zener-type TVS diode configuration
• Through-hole mounting with P600 axial package
• Operating temperature range: -55°C to 175°C (TJ)
• ROHS3 compliance and MSL 1 rating
• General-purpose transient voltage suppression applications

Substitution Logic: Substitute parts are grouped by peak pulse power rating, which determines the magnitude of transient energy the device can dissipate. The 30KPA78CE3/TR13 operates at 30kW peak pulse power. Direct substitutes maintain this 30kW rating, while similar substitutes operate at reduced power levels (15kW or 5kW) and are suitable for applications with lower transient energy requirements. All substitutes maintain the 78V reverse standoff voltage and compatible electrical characteristics within the specified breakdown and clamping voltage ranges.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (30KPA78CA): The 30KPA78CA manufactured by MDE Semiconductor Inc is a direct electrical equivalent to the 30KPA78CE3/TR13. Both devices maintain identical reverse standoff voltage (78V), equivalent breakdown voltage specifications, and matching 30kW peak pulse power rating. The 30KPA78CA is ROHS3 compliant with MSL 1 rating and operates across the same temperature range (-55°C to 175°C TJ). This substitute is suitable for applications requiring full power dissipation capacity equivalent to the primary part. The primary difference is packaging format (Bulk versus Tape & Reel) and manufacturer source.

Similar Substitutes (15KPA78CA and 5KP78CA): The 15KPA78CA and 5KP78CA are suitable substitutes for applications where peak pulse power requirements are lower than 30kW. Both maintain the 78V reverse standoff voltage and compatible breakdown voltage characteristics. The 15KPA78CA provides 15kW peak pulse power capacity, while the 5KP78CA provides 5kW capacity. Both are ROHS3 compliant with MSL 1 rating and full operating temperature range compatibility. Selection between these lower-power alternatives depends on the specific transient energy profile of the application circuit.

All substitute parts maintain Active product status and are available in standard inventory quantities.

Frequently Asked Questions (FAQ)

Q: Can the 30KPA78CA be used as a direct replacement for the 30KPA78CE3/TR13?

A: Yes. The 30KPA78CA is a direct electrical equivalent with matching reverse standoff voltage (78V), breakdown voltage, and peak pulse power rating (30kW). Both devices are Zener-type bidirectional TVS diodes in P600 axial through-hole packaging with identical operating temperature ranges and compliance certifications. The primary difference is packaging format and manufacturer.

Q: What is the difference between the 30KPA78CA and the 15KPA78CA?

A: The primary difference is peak pulse power rating. The 30KPA78CA dissipates 30kW peak pulse power, while the 15KPA78CA dissipates 15kW. Both maintain the same 78V reverse standoff voltage and compatible breakdown voltage. The 15KPA78CA is suitable for applications with lower transient energy requirements and lower peak pulse current (119.7A versus 234A).

Q: Can the 5KP78CA be used in place of the 30KPA78CE3/TR13?

A: The 5KP78CA is electrically compatible in terms of voltage characteristics (78V reverse standoff voltage) but is rated for only 5kW peak pulse power compared to the 30kW rating of the primary part. Use the 5KP78CA only in applications where transient energy levels do not exceed 5kW. Exceeding this power rating will result in device failure.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The 30KPA78CA, 15KPA78CA, and 5KP78CA are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the compliance profile of the 30KPA78CE3/TR13.

Q: What is the difference between Tape & Reel and Bulk packaging?

A: Tape & Reel packaging is used for automated assembly processes and provides components wound on continuous tape. Bulk packaging provides loose components. Both formats contain identical electronic components. Selection depends on manufacturing process requirements. The 30KPA78CE3/TR13 and 5KP78CA are supplied in Tape & Reel format, while the 30KPA78CA and 15KPA78CA are supplied in Bulk format.

Q: Do all substitute parts operate across the same temperature range?

A: Yes. All substitute parts (30KPA78CA, 15KPA78CA, and 5KP78CA) operate across the identical temperature range of -55°C to 175°C (TJ), matching the 30KPA78CE3/TR13.

Q: What determines whether a substitute part is suitable for my application?

A: The primary selection criteria are reverse standoff voltage (78V for all listed substitutes), peak pulse power rating (select based on transient energy requirements), and package type (all are P600 axial through-hole). Verify that the substitute's peak pulse power rating meets or exceeds your application's maximum transient energy dissipation requirement.
