Littelfuse P3100EB TVS Thyristor Equivalent & Substitute Parts

Part Overview

The Littelfuse P3100EB is a 275V off-state, 250A peak pulse (8/20µs) transient voltage suppressor thyristor in TO-226-2 package configuration. This component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing design support and procurement continuity. The P3100EB operates as a SIDACtor® device, providing transient voltage suppression through thyristor-based switching at specified breakover voltage thresholds.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P3100EB is determined by electrical and mechanical parameter equivalence within the SIDACtor® product family. The substitute part P3100EBL maintains identical electrical specifications across all critical parameters: breakover voltage (350V), off-state voltage (275V), on-state voltage (4V), peak pulse current ratings (250A at 8/20µs and 80A at 10/1000µs), hold current (150mA), and capacitance (45pF). Both parts share the same package configuration (TO-226-2, TO-92-2) and through-hole mounting type, ensuring mechanical and electrical compatibility in existing circuit designs.

The key substitution criteria are:

• Identical voltage ratings (breakover, off-state, on-state)
• Identical current ratings (peak pulse and hold current)
• Identical capacitance specification
• Identical package and mounting configuration
• Same number of elements (1)

Parameter Comparison

Engineering Selection Recommendations

The P3100EBL is the direct functional equivalent of the P3100EB for transient voltage suppression applications. Selection of P3100EBL is supported by:

• Complete electrical parameter equivalence across all voltage and current ratings
• Identical mechanical package configuration enabling direct board-level substitution
• Active product status ensuring ongoing availability and supply chain continuity
• ROHS3 compliance status, addressing regulatory requirements for new designs and procurement cycles
• Maintained SIDACtor® series classification and performance characteristics

The transition from P3100EB to P3100EBL does not require circuit redesign or performance re-evaluation when electrical and mechanical parameters remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can P3100EBL be used as a direct replacement for P3100EB in existing designs?

A: Yes. The P3100EBL maintains identical electrical specifications (voltage ratings, current ratings, capacitance) and package configuration (TO-226-2, TO-92-2, through-hole mounting). No circuit modifications are required.

Q: What is the primary difference between P3100EB and P3100EBL?

A: The P3100EB is obsolete with non-compliant RoHS status. The P3100EBL is an active product with ROHS3 compliance. All electrical and mechanical parameters are identical.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the same TO-226-2 and TO-92-2 package configurations with identical through-hole mounting specifications.

Q: Why is the P3100EB classified as obsolete?

A: The P3100EB has reached end-of-life status. The P3100EBL serves as the active equivalent within the SIDACtor® product family.

Q: What certifications apply to the P3100EBL?

A: The P3100EBL is ROHS3 compliant and REACH unaffected. The P3100EB is RoHS non-compliant.

Q: Can inventory of P3100EB be used interchangeably with P3100EBL?

A: Yes, from an electrical and mechanical standpoint. However, regulatory compliance requirements may dictate use of the ROHS3-compliant P3100EBL for new production or designs subject to environmental regulations.
