P0300EB Equivalent & Substitute Parts

Part Overview

The P0300EB is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc. in the SIDACtor® series. This component is designed for 25V off-state voltage suppression applications with a peak pulse current rating of 250A (8/20µs). The P0300EB is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P0300EB is determined by matching the following critical electrical and mechanical parameters:

• Voltage ratings: Breakover voltage of 40V, off-state voltage of 25V, and on-state voltage of 4V
• Current specifications: Peak pulse current of 250A (8/20µs) and 80A (10/1000µs), with hold current of 50mA
• Package compatibility: TO-226-2 or TO-92-2 (TO-226AC) through-hole mounting
• Capacitance: 140pF

The P0300EBL meets all these electrical and mechanical requirements and is classified as the manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

The P0300EBL is the direct substitute for the obsolete P0300EB. Both components share identical electrical specifications and package configurations, ensuring functional equivalence in circuit applications. The P0300EBL offers the additional advantage of active product status, ensuring long-term availability and supply chain continuity. The P0300EBL also meets ROHS3 compliance requirements, whereas the P0300EB is non-compliant. For new designs or component replenishment, the P0300EBL is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the P0300EBL directly replace the P0300EB in existing designs?

A: Yes. The P0300EBL provides identical electrical performance across all rated parameters, including voltage ratings, peak pulse currents, and hold current specifications. The through-hole package configuration (TO-226-2, TO-92-2) is identical, allowing direct PCB-level substitution without circuit modification.

Q: What is the primary reason for substituting the P0300EB?

A: The P0300EB is classified as obsolete. The P0300EBL is the active equivalent, ensuring component availability and supply chain reliability for ongoing production and field support.

Q: Are there compliance differences between the two parts?

A: Yes. The P0300EB is RoHS non-compliant, while the P0300EBL is ROHS3 compliant. Both components share the same ECCN (EAR99) and HTSUS classifications. If RoHS compliance is required for your application, the P0300EBL is the appropriate choice.

Q: Do the packaging options differ between P0300EB and P0300EBL?

A: No. Both components are available in TO-226-2 and TO-92-2 (TO-226AC) through-hole packages. The P0300EBL is supplied in bulk packaging, whereas the P0300EB packaging type was not specified in the original documentation.

Q: Are the electrical characteristics identical between these parts?

A: Yes. Breakover voltage, off-state voltage, on-state voltage, peak pulse currents, hold current, capacitance, and all other electrical parameters are identical between the P0300EB and P0300EBL.
