30KPA33AE3/TR13 Equivalent & Substitute Parts

Part Overview

The 30KPA33AE3/TR13 is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose transient protection applications. This component features a 33V reverse standoff voltage with a 58.5V maximum clamping voltage and peak pulse current capability of 517.9A at 30kW peak pulse power. The device is housed in a P600 axial through-hole package and is supplied in Tape & Reel (TR) packaging format. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified based on matching or closely aligned electrical performance parameters within the TVS diode category, specifically reverse standoff voltage, clamping voltage characteristics, peak pulse current ratings, and through-hole axial package compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 30KPA33AE3/TR13 are classified into two categories based on electrical parameter alignment:

Direct Equivalents (Functionally Interchangeable): Parts matching the primary electrical specifications: 33V reverse standoff voltage, 36.9V minimum breakdown voltage, 58.5V clamping voltage, and 517.9A peak pulse current capability within the 30kW power dissipation class. These parts maintain identical through-hole P600 axial package configuration and operating temperature range (-55°C to 175°C).

Similar Substitutes (Reduced Performance Rating): Parts with matching 33V reverse standoff voltage and compatible through-hole P600 axial packaging but with reduced peak pulse current ratings (94A to 276.1A) and lower peak pulse power dissipation (5kW to 15kW). These parts are suitable for applications with lower transient energy requirements while maintaining voltage protection characteristics.

Key Parameters for Substitution Determination:

• Reverse Standoff Voltage: 33V (required match)
• Breakdown Voltage (Min): 36.6V to 36.9V (acceptable range)
• Clamping Voltage: 53.3V to 76V (application-dependent selection)
• Peak Pulse Current: 94A to 517.9A (application-dependent)
• Peak Pulse Power: 5kW to 30kW (application-dependent)
• Package Type: P600 or R-6 axial through-hole (mechanical compatibility)
• Unidirectional Configuration: Single channel (required match)

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (30kW Peak Pulse Power Requirement): The 30KPA33A from MDE Semiconductor Inc is the primary direct equivalent, offering 517.2A peak pulse current and 30kW peak pulse power dissipation with identical 33V reverse standoff voltage and 58.5V clamping voltage. Both parts maintain ROHS3 compliance and Active product status. The 30KPA33A is available in bulk packaging with 1929 units in stock, compared to 666 units of the original part in Tape & Reel format.

For Reduced Power Applications (15kW Peak Pulse Power): The 15KPA33A from MDE Semiconductor Inc provides 276.1A peak pulse current with 15kW peak pulse power dissipation. This part maintains the 33V reverse standoff voltage and is suitable for applications with lower transient energy requirements. ROHS3 compliance and Active product status are maintained.

For Lower Power Applications (5kW Peak Pulse Power): The 5KP33A-E3/54 and 5KP33AHE3/54 from Vishay General Semiconductor - Diodes Division both deliver 93.8A peak pulse current with 5kW peak pulse power dissipation. The 5KP33AHE3/54 variant includes AEC-Q101 automotive qualification. Both maintain ROHS3 compliance and Active product status. The 5KP33A from Diotec Semiconductor offers equivalent electrical performance but lacks ROHS3 compliance documentation.

For Higher Clamping Voltage Applications: The BZW50-33 and BZW50-33RL from STMicroelectronics feature 76V clamping voltage with 789A peak pulse current (8/20µs pulse definition) and 5kW peak pulse power. These parts use R-6 axial package configuration instead of P600. ROHS3 compliance and Active product status are maintained. Package mechanical differences require verification for board-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 30KPA33A directly replace the 30KPA33AE3/TR13? A: Yes. The 30KPA33A provides equivalent electrical performance with 517.2A peak pulse current, 58.5V clamping voltage, and 30kW peak pulse power. Both parts maintain 33V reverse standoff voltage and through-hole P600 axial package configuration. The primary difference is packaging format: the original part is supplied in Tape & Reel (TR), while the substitute is supplied in bulk.

Q: What is the difference between the 5KP33A-E3/54 and 5KP33AHE3/54? A: Both parts provide identical electrical specifications: 93.8A peak pulse current, 53.3V clamping voltage, and 5kW peak pulse power. The 5KP33AHE3/54 includes AEC-Q101 automotive qualification and is designated for automotive applications. Both maintain ROHS3 compliance and Active product status.

Q: Can I use a 5kW rated part in place of a 30kW rated part? A: No. The 5kW rated parts (5KP33A-E3/54, 5KP33AHE3/54, 5KP33A) are suitable only for applications with lower transient energy requirements. Using a lower power-rated part in a 30kW application will result in component failure. Application transient energy specifications must be verified before substitution.

Q: What is the difference between P600 and R-6 package configurations? A: Both are through-hole axial packages for TVS diodes. The P600 package is used by Microchip Technology, MDE Semiconductor Inc, Diotec Semiconductor, and Vishay. The R-6 package is used by STMicroelectronics for the BZW50 series. Physical dimensions and lead spacing differ between these packages. Board-level mechanical compatibility must be verified before substitution.

Q: Are all substitute parts ROHS3 compliant? A: The 30KPA33A, 15KPA33A, 5KP33A-E3/54, 5KP33AHE3/54, BZW50-33, and BZW50-33RL are ROHS3 compliant. The 5KP33A from Diotec Semiconductor does not have applicable ROHS3 documentation. Compliance requirements for your application must be verified before part selection.

Q: What is the operating temperature range for these parts? A: The 30KPA33AE3/TR13, 30KPA33A, 15KPA33A, 5KP33A-E3/54, and 5KP33AHE3/54 operate from -55°C to 175°C (TJ). The 5KP33A operates from -50°C to 175°C (TJ). The BZW50-33 and BZW50-33RL do not have specified operating temperature ranges in the provided data. Application temperature requirements must be verified for compatibility.

Q: Can I substitute based on clamping voltage alone? A: No. Clamping voltage is one parameter among several that determine substitution suitability. Reverse standoff voltage (33V for all listed parts), peak pulse current capability, peak pulse power rating, and package configuration must all be verified for application compatibility. Transient energy specifications and circuit protection requirements must be evaluated before substitution.
