Littelfuse P2300SC TVS Thyristor Equivalent & Substitute Parts

Part Overview

The Littelfuse P2300SC is a 190V off-state, 400A peak pulse TVS thyristor in DO-214AA (SMB) surface mount package, part of the SIDACtor® series. This component is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. The P2300SC provides transient voltage suppression with a 260V breakover voltage and 4V on-state voltage, suitable for protecting circuits from overvoltage transients.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the P2300SC is determined by the following critical parameters:

• Voltage - Off State: 190V (primary electrical specification)
• Voltage - Breakover: 260V (transient suppression threshold)
• Current - Peak Pulse (8/20µs): 400A (surge handling capability)
• Package / Case: DO-214AA, SMB (mechanical and thermal compatibility)
• Mounting Type: Surface Mount (PCB assembly compatibility)

The P2300SC has two identified substitutes: the P2300SCLRP (direct equivalent with different packaging) and the SMP100LC-200 (manufacturer-recommended alternative with minor electrical variations).

Parameter Comparison

Engineering Selection Recommendations

P2300SCLRP (Littelfuse Inc.): This is the direct functional equivalent of the P2300SC with identical electrical specifications and package. The primary difference is packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete). P2300SCLRP is ROHS3 compliant, making it suitable for applications requiring regulatory compliance. This substitute is recommended for designs requiring exact electrical parameter matching and continued Littelfuse product support.

SMP100LC-200 (STMicroelectronics): This manufacturer-recommended alternative operates at 200V off-state and 250V breakover voltage, representing a 10V increase in both parameters compared to the P2300SC. Peak pulse current ratings (400A at 8/20µs, 100A at 10/1000µs) and hold current (150mA) remain identical. Capacitance is reduced to 60pF. Both parts share the DO-214AA, SMB package and surface mount configuration. SMP100LC-200 is ROHS3 compliant and REACH unaffected. This substitute is applicable where the higher voltage rating is acceptable within circuit design margins.

Frequently Asked Questions (FAQ)

Q: Can P2300SCLRP be used as a direct replacement for P2300SC?

A: Yes. P2300SCLRP is electrically and mechanically identical to P2300SC. The only differences are packaging format (Tape & Reel) and product status (Active). Both share identical voltage ratings, current ratings, and DO-214AA, SMB package specifications.

Q: What are the electrical differences between P2300SC and SMP100LC-200?

A: SMP100LC-200 has a 10V higher off-state voltage (200V versus 190V) and 10V lower breakover voltage (250V versus 260V). Peak pulse current, hold current, and package remain identical. Capacitance differs (60pF versus 80pF). These differences must be evaluated against circuit protection requirements.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the DO-214AA, SMB package with surface mount configuration, ensuring mechanical and thermal compatibility on the same PCB layout.

Q: What compliance advantages do the substitute parts offer?

A: Both P2300SCLRP and SMP100LC-200 are ROHS3 compliant, whereas the original P2300SC is RoHS non-compliant. This makes the substitutes suitable for applications requiring regulatory compliance with modern environmental standards.

Q: Which substitute should be selected for new designs?

A: P2300SCLRP is recommended for new designs requiring exact electrical parameter matching and continued support from the original manufacturer. SMP100LC-200 is suitable where the higher voltage rating accommodates circuit design margins and cross-manufacturer sourcing is acceptable.
