P0720EC Equivalent & Substitute Parts

Part Overview

The P0720EC is a 65V off-state, 400A peak pulse TVS thyristor manufactured by Littelfuse in the SIDACtor® series. This component is designed for transient voltage suppression applications requiring high current handling capability in a compact TO-226-2 package. The P0720EC is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P0720EC is determined by strict equivalence across all electrical and mechanical parameters. The primary substitution criterion is matching the complete electrical specification set: 88V breakover voltage, 65V off-state voltage, 4V on-state voltage, 400A peak pulse current (8/20µs), 100A peak pulse current (10/1000µs), 150mA hold current, and 150pF capacitance. The package type must remain TO-226-2 or TO-92-2 (TO-226AC) to ensure mechanical and thermal compatibility. The number of elements must be 1. All substitute parts must maintain these parameters without deviation to ensure functional equivalence in transient voltage suppression circuits.

Parameter Comparison

Engineering Selection Recommendations

The P0720ECL is the direct functional equivalent of the P0720EC. Both components share identical electrical specifications and package configurations, ensuring drop-in compatibility in existing circuit designs. The primary distinction is product status and regulatory compliance: the P0720EC is obsolete, while the P0720ECL maintains active production status. Additionally, the P0720ECL achieves ROHS3 compliance, whereas the P0720EC is RoHS non-compliant. For new designs and ongoing system support, the P0720ECL is the appropriate selection due to its active availability and improved regulatory standing.

Frequently Asked Questions (FAQ)

Q: Can the P0720ECL replace the P0720EC in existing applications? A: Yes. The P0720ECL is electrically and mechanically identical to the P0720EC across all specified parameters, including breakover voltage, peak pulse current ratings, on-state voltage, hold current, and package type. Direct substitution is supported.

Q: What is the difference between P0720EC and P0720ECL? A: The components are electrically equivalent. The P0720EC is classified as obsolete with RoHS non-compliant status. The P0720ECL is in active production and meets ROHS3 compliance requirements. Both use the same TO-226-2 package and deliver identical performance in transient voltage suppression circuits.

Q: Are there any package or pinout differences? A: No. Both the P0720EC and P0720ECL use the TO-226-2 and TO-92-2 (TO-226AC) package configurations with identical pinouts and mechanical dimensions. Through-hole mounting compatibility is maintained.

Q: Why is the P0720EC listed as obsolete? A: The P0720EC has reached end-of-life status in Littelfuse's product portfolio. The P0720ECL serves as the active production equivalent, offering the same electrical performance with improved regulatory compliance.

Q: What are the key electrical parameters that define substitution compatibility? A: Substitution is based on exact matching of: 88V breakover voltage, 65V off-state voltage, 4V on-state voltage, 400A peak pulse current (8/20µs), 100A peak pulse current (10/1000µs), 150mA hold current, 150pF capacitance, and single-element configuration. Package type must remain TO-226-2 or TO-92-2 (TO-226AC).
