P0300EC Equivalent & Substitute Parts

Part Overview

The P0300EC is a 25V off-state TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series, designed for transient voltage suppression applications. This component operates with a 40V breakover voltage and handles peak pulse currents of 400A (8/20µs). The P0300EC is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P0300EC is determined by electrical parameter equivalence and package compatibility. The critical parameters for substitution are:

• Voltage - Off State: 25V
• Voltage - Breakover: 40V
• Voltage - On State: 4V
• Current - Peak Pulse (8/20µs): 400A
• Current - Peak Pulse (10/1000µs): 100A
• Current - Hold (Ih): 50mA
• Capacitance: 250pF
• Package / Case: TO-226-2, TO-92-2 (TO-226AC)

The P0300ECL meets all electrical specifications and maintains identical package configuration, establishing it as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The P0300ECL is the direct substitute for the P0300EC. Both components are manufactured by Littelfuse Inc. and share identical electrical specifications and package configuration. The primary distinction is product status: the P0300EC is obsolete while the P0300ECL is active. Additionally, the P0300ECL carries ROHS3 compliance, whereas the P0300EC is non-compliant. For new designs or ongoing procurement, the P0300ECL is the appropriate selection due to its active status and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the P0300ECL directly replace the P0300EC in existing designs?

A: Yes. The P0300ECL provides identical electrical performance and package configuration. No circuit modifications are required.

Q: What is the difference between P0300EC and P0300ECL?

A: The components are electrically equivalent. The P0300ECL is the active production variant with ROHS3 compliance, while the P0300EC is obsolete and RoHS non-compliant.

Q: Are there any package differences between these parts?

A: No. Both parts use the TO-226-2, TO-92-2 (TO-226AC) package with through-hole mounting.

Q: What are the critical electrical parameters for substitution?

A: Off-state voltage (25V), breakover voltage (40V), on-state voltage (4V), peak pulse current (400A at 8/20µs), and capacitance (250pF) must remain constant for functional equivalence.

Q: Is the P0300ECL available in different packaging options?

A: The P0300ECL is supplied in bulk packaging, whereas the P0300EC packaging type was not specified in the original documentation.
