Littelfuse P1100EB TVS Thyristor Equivalent & Substitute Parts

Part Overview

The Littelfuse P1100EB is a 90V off-state, 250A peak pulse TVS thyristor in TO-226-2 packaging, part of the SIDACtor® series. This component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing design requirements and procurement needs. The P1100EB provides transient voltage suppression through a thyristor topology with specified breakover and holding characteristics suitable for overvoltage protection applications.

Substitute Part Grouping Explanation

Substitution of the P1100EB is determined by electrical and mechanical parameter equivalence. The following criteria establish direct substitutability:

• Voltage - Breakover: 130V
• Voltage - Off State: 90V
• Voltage - On State: 4V
• Current - Peak Pulse (8/20µs): 250A
• Current - Peak Pulse (10/1000µs): 80A
• Current - Hold (Ih): 150mA
• Capacitance: 70pF
• Number of Elements: 1
• Package / Case: TO-226-2, TO-92-2 (TO-226AC)
• Mounting Type: Through Hole

The P1100EBL meets all specified electrical and mechanical parameters, providing direct functional equivalence to the obsolete P1100EB.

Parameter Comparison

Engineering Selection Recommendations

The P1100EBL is the direct equivalent for the obsolete P1100EB. Both components share identical electrical specifications and mechanical packaging. The P1100EBL is currently in active production status with improved regulatory compliance: it meets ROHS3 requirements and carries REACH Unaffected status, whereas the P1100EB is RoHS non-compliant. For new designs or component replacement in existing applications, the P1100EBL provides equivalent performance with enhanced compliance posture. Packaging is available in bulk format for the P1100EBL, supporting production-scale procurement.

Frequently Asked Questions (FAQ)

Q: Can the P1100EBL directly replace the P1100EB in existing designs?

A: Yes. The P1100EBL provides identical electrical and mechanical specifications. Both components feature 90V off-state voltage, 250A peak pulse current (8/20µs), 130V breakover voltage, and TO-226-2 packaging. Direct substitution is supported without circuit modification.

Q: What is the primary reason to transition from P1100EB to P1100EBL?

A: The P1100EB is obsolete. The P1100EBL is the active equivalent, ensuring ongoing availability and supply chain continuity. Additionally, the P1100EBL meets ROHS3 compliance requirements, whereas the P1100EB does not.

Q: Are the package dimensions identical between P1100EB and P1100EBL?

A: Yes. Both components use TO-226-2 and TO-92-2 (TO-226AC) packaging with through-hole mounting. PCB layout and mechanical integration remain unchanged.

Q: What compliance certifications differentiate these parts?

A: The P1100EBL is ROHS3 compliant and REACH Unaffected. The P1100EB is RoHS non-compliant. For applications subject to environmental or regulatory requirements, the P1100EBL is the appropriate selection.

Q: Is there a difference in electrical performance between these parts?

A: No. Voltage ratings, current ratings, capacitance, and holding current specifications are identical. Performance in transient voltage suppression applications is equivalent.
