Littelfuse P0080EA TVS Thyristor Equivalent & Substitute Parts

Part Overview

The Littelfuse P0080EA is a 6V off-state transient voltage suppressor thyristor in the SIDACtor® series, rated for 150 A peak pulse current (8/20µs). This component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing design support and procurement. The P0080EA operates in TO-226-2 and TO-92-2 package configurations and is designed for transient voltage suppression applications requiring high peak current handling.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P0080EA is determined by electrical and mechanical parameter equivalence. The primary substitution criteria are:

• Voltage ratings: Breakover voltage (25V), off-state voltage (6V), and on-state voltage (4V) must match exactly
• Current specifications: Peak pulse current (8/20µs) of 150 A and (10/1000µs) of 45 A must be identical
• Hold current (Ih) of 50 mA must be maintained
• Capacitance of 150 pF must be preserved
• Package configuration: TO-226-2 or TO-92-2 (TO-226AC) through-hole mounting
• Series classification: SIDACtor® family

The P0080EAL meets all these criteria and is classified as an active product, making it a direct electrical and mechanical equivalent suitable for replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The P0080EAL is the direct substitute for the obsolete P0080EA. All electrical parameters and mechanical specifications are identical. The P0080EAL carries active product status and ROHS3 compliance, providing advantages for new designs and procurement continuity. The P0080EAL is available in bulk packaging with significantly higher inventory levels (20,200 pcs) compared to the original part, ensuring supply chain reliability.

For applications currently using the P0080EA, direct replacement with P0080EAL requires no circuit modifications or design changes. The identical electrical characteristics and package configuration ensure pin-for-pin compatibility.

Frequently Asked Questions (FAQ)

Q: Can P0080EAL be used as a direct replacement for P0080EA? A: Yes. All electrical parameters, including voltage ratings, current specifications, capacitance, and hold current, are identical. The package configuration and mounting type are also equivalent. No circuit modifications are required.

Q: What is the difference between P0080EA and P0080EAL? A: The primary differences are product status and compliance. P0080EA is obsolete and RoHS non-compliant. P0080EAL is active and ROHS3 compliant. Electrically and mechanically, both parts are identical.

Q: Are there packaging differences between these parts? A: P0080EA is supplied in standard packaging, while P0080EAL is supplied in bulk packaging. Both use the same TO-226-2 and TO-92-2 (TO-226AC) through-hole package configurations with identical pin assignments.

Q: What are the key parameters that determine substitution eligibility? A: Substitution is determined by matching voltage ratings (breakover, off-state, and on-state), peak pulse current specifications (8/20µs and 10/1000µs), hold current, capacitance, package type, and series classification. All these parameters must be identical for direct substitution.

Q: Is P0080EAL suitable for new designs? A: Yes. P0080EAL is an active product with ROHS3 compliance, making it appropriate for new designs and long-term procurement planning.
