Littelfuse P0080EARP2 TVS Thyristor Equivalent & Substitute Parts

Part Overview

The Littelfuse P0080EARP2 is a 6V off-state transient voltage suppressor (TVS) thyristor in the SIDACtor® series, rated for 150 A peak pulse current (8/20µs). This component is designed for overvoltage protection in electronic circuits requiring fast transient suppression. The P0080EARP2 is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P0080EARP2 is determined by matching the following critical electrical and mechanical parameters:

• Voltage ratings (breakover, off-state, and on-state)
• Peak pulse current ratings (both 8/20µs and 10/1000µs specifications)
• Hold current (Ih)
• Capacitance
• Package type and form factor (TO-226-2, TO-92-2)
• Number of elements (single element configuration)

The P0080EALRP2 meets all these criteria and serves as the direct equivalent. The primary distinction between these parts is product status and packaging format, not electrical performance.

Parameter Comparison

Engineering Selection Recommendations

The P0080EALRP2 is the direct functional equivalent to the P0080EARP2. Selection between these parts should be based on the following factors:

Product Status: The P0080EARP2 is obsolete. For new designs and long-term production continuity, the P0080EALRP2 is the appropriate choice as an active product.

Regulatory Compliance: The P0080EALRP2 is ROHS3 compliant, whereas the P0080EARP2 is non-compliant. Applications subject to RoHS regulations require the P0080EALRP2.

Packaging: The P0080EALRP2 is supplied in Tape & Reel format, suitable for automated assembly. The P0080EARP2 was supplied in bulk packaging. Packaging selection depends on production volume and assembly methodology.

Electrical Performance: Both parts are electrically identical across all specified parameters and are interchangeable at the circuit level.

Frequently Asked Questions (FAQ)

Q: Can the P0080EALRP2 directly replace the P0080EARP2 in existing designs?

A: Yes. The P0080EALRP2 is electrically identical to the P0080EARP2 across all specified parameters, including voltage ratings, peak pulse currents, hold current, and capacitance. Both use the same TO-226-2/TO-92-2 package with through-hole mounting. Direct substitution is possible at the circuit level.

Q: What is the primary reason to transition from P0080EARP2 to P0080EALRP2?

A: The P0080EARP2 is classified as obsolete. The P0080EALRP2 is an active product from the same manufacturer and series, ensuring ongoing availability and supply chain continuity. Additionally, the P0080EALRP2 meets ROHS3 compliance requirements.

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

A: Both parts use the same TO-226-2/TO-92-2 package with formed leads and through-hole mounting. The difference is in packaging format: the P0080EARP2 was supplied in bulk, while the P0080EALRP2 is supplied in Tape & Reel format for automated assembly.

Q: Do these parts have identical electrical specifications?

A: Yes. Both parts share identical specifications for breakover voltage (25V), off-state voltage (6V), on-state voltage (4V), peak pulse currents (150 A at 8/20µs and 45 A at 10/1000µs), hold current (50 mA), and capacitance (150pF).

Q: Is the P0080EALRP2 suitable for applications requiring RoHS compliance?

A: Yes. The P0080EALRP2 is ROHS3 compliant. The P0080EARP2 is non-compliant. Applications subject to RoHS regulations must use the P0080EALRP2.
