30KPA30E3/TR13 Equivalent & Substitute Parts

Part Overview

The 30KPA30E3/TR13 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This component features a 30V reverse standoff voltage rating with 30kW peak pulse power handling capability in a through-hole P600 axial package. The part is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance parameters align with the main device specifications, allowing direct functional replacement in circuit designs while maintaining protection characteristics and thermal operating ranges.

Substitute Part Grouping Explanation

Substitute parts for the 30KPA30E3/TR13 are classified based on alignment with critical electrical parameters: reverse standoff voltage (30V nominal), unidirectional channel configuration (single channel), through-hole mounting, and zener diode type. Parts are grouped into two categories:

Direct Substitutes (Full Parameter Match): Parts maintaining 30V reverse standoff voltage, 30kW peak pulse power rating, P600 axial package, and operating temperature range of -55°C to 175°C.

Functional Alternatives (Reduced Power Rating): Parts with 30V reverse standoff voltage and compatible package geometry but lower peak pulse power ratings (15kW or 5kW), suitable for applications with reduced transient energy requirements.

Voltage Deviation Alternatives (Near-Equivalent): Parts with 28V reverse standoff voltage, maintaining compatible package and mounting type but with reduced power handling and clamping voltage characteristics.

The following parameters determine substitution eligibility:

Reverse standoff voltage: 30V (primary criterion)
Unidirectional configuration: Single channel required
Package type: P600 axial or compatible through-hole geometry
Zener diode type: Required
Operating temperature minimum: -55°C or higher
RoHS3 compliance: Required

Engineering Selection Recommendations

30KPA30A (MDE Semiconductor Inc): Direct equivalent substitute with identical 30V reverse standoff voltage, 30kW peak pulse power rating, and P600 axial package. Maintains full operating temperature range (-55°C to 175°C) and RoHS3 compliance. Higher clamping voltage (55.2V) and peak pulse current (548.9A) provide enhanced transient suppression. Suitable for direct replacement in all applications requiring 30kW power handling.

5KP30A-E3/54 (Vishay General Semiconductor - Diodes Division): Maintains 30V reverse standoff voltage, P600 axial package, and full operating temperature range (-55°C to 175°C). Reduced peak pulse power rating (5kW) limits application to lower-energy transient environments. RoHS3 compliant with REACH unaffected status. Appropriate for applications with transient energy below 5kW threshold.

15KPA30A (Good-Ark Semiconductor): Intermediate power rating (15kW) with 30V reverse standoff voltage and P600 axial package. Operating temperature range limited to -55°C to 150°C (10°C lower maximum than main part). RoHS3 compliant. Suitable for moderate transient protection applications where 30kW rating is not required.

5KP30A (Diotec Semiconductor): Lowest power rating (5kW) among 30V alternatives. Operating temperature minimum of -50°C (5°C higher than main part) may restrict use in extreme cold environments. P600 axial package and RoHS3 compliance maintained. Applicable to low-energy transient suppression circuits.

LCE28A (Littelfuse Inc.): Voltage deviation alternative with 28V reverse standoff (2V lower than main part). Significantly reduced power handling (1.5kW) and peak pulse current (33A). DO-201 package differs from P600 geometry. Full operating temperature range (-55°C to 175°C) and RoHS3 compliance maintained. Limited to minimal transient energy applications with voltage tolerance for 28V operation.

Frequently Asked Questions (FAQ)

Q: Can the 30KPA30A directly replace the 30KPA30E3/TR13 in existing circuit designs?

A: Yes. The 30KPA30A maintains identical reverse standoff voltage (30V), peak pulse power rating (30kW), package geometry (P600 axial), and operating temperature range (-55°C to 175°C). Both components are RoHS3 compliant and zener-type unidirectional TVS diodes. Direct substitution is functionally equivalent.

Q: What is the primary difference between the 30KPA30E3/TR13 and the 5KP30A-E3/54?

A: The primary difference is peak pulse power rating: 30kW versus 5kW. Both maintain 30V reverse standoff voltage and P600 axial package. The 5KP30A-E3/54 is suitable only for applications with transient energy below 5kW. Clamping voltage is lower (48.4V versus unspecified for main part), and peak pulse current is reduced (103A versus unspecified).

Q: Is the LCE28A suitable as a substitute for the 30KPA30E3/TR13?

A: The LCE28A is not a direct substitute. While it maintains through-hole mounting and RoHS3 compliance, it differs in three critical parameters: reverse standoff voltage (28V versus 30V), peak pulse power rating (1.5kW versus 30kW), and package type (DO-201 versus P600). Use only in applications with 28V voltage tolerance and minimal transient energy requirements.

Q: What packaging options are available for 30V TVS diodes equivalent to the 30KPA30E3/TR13?

A: All direct and functional alternatives maintain through-hole axial package configurations. The 30KPA30A, 15KPA30A, 5KP30A, and 5KP30A-E3/54 use P600 axial packages identical to the main part. The LCE28A uses DO-201 axial package, which differs in physical dimensions. Packaging format (Tape & Reel, Bulk, or Cut Tape) affects procurement and assembly handling but does not impact electrical performance.

Q: Does operating temperature range affect substitution eligibility?

A: Operating temperature range is a selection criterion for specific applications. The 15KPA30A has a maximum operating temperature of 150°C (versus 175°C for the main part), which may restrict use in high-temperature environments. The 5KP30A has a minimum operating temperature of -50°C (versus -55°C), which may restrict use in extreme cold environments. Verify application temperature requirements before selection.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (30KPA30A, 15KPA30A, 5KP30A, 5KP30A-E3/54, and LCE28A) are RoHS3 compliant, matching the compliance status of the 30KPA30E3/TR13. REACH status varies by manufacturer but does not affect functional substitution.

Q: What determines whether a lower-power TVS diode can substitute for the 30KPA30E3/TR13?

A: Substitution with lower-power alternatives (15kW or 5kW) is determined by application transient energy requirements. If the circuit experiences transient pulses below the lower-power rating, the substitute is functionally adequate. If transient energy exceeds the substitute's power rating, the device will fail to suppress overvoltage. Verify actual transient energy in the application before selecting a lower-power alternative.
