NP2300SCMCT3G Equivalent & Substitute Parts

Part Overview

The NP2300SCMCT3G is a 190V off-state, 400A peak pulse TVS thyristor manufactured by onsemi in DO-214AA (SMB) surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The part functions as a transient voltage suppressor for circuit protection applications requiring high current pulse handling capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the NP2300SCMCT3G is determined by the following critical parameters:

• Voltage - Off State: Must be 190V (primary protection threshold)
• Package / Case: Must be DO-214AA, SMB (mechanical and thermal compatibility)
• Mounting Type: Must be Surface Mount (PCB assembly compatibility)
• Number of Elements: Must be 1 (functional equivalence)
• Current - Hold (Ih): Must be 150mA (trigger and holding characteristics)

Substitute parts are grouped into two categories:

Direct Equivalents maintain all critical electrical parameters within the same tolerance band, enabling drop-in replacement without circuit redesign.

Similar Substitutes maintain core voltage and package specifications but may vary in peak pulse current ratings or on-state voltage, requiring application-level verification of current handling requirements.

Parameter Comparison

Engineering Selection Recommendations

P2300SCLRP (Littelfuse Inc.) is the primary direct equivalent. This part maintains identical electrical specifications for off-state voltage (190V), breakover voltage (260V), on-state voltage (4V), and peak pulse currents (400A at 8/20µs, 100A at 10/1000µs). The part is active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Higher capacitance (80pF vs. 33pF) may affect high-frequency transient response characteristics and should be evaluated for specific circuit applications.

P2300SCMCLRP (Littelfuse Inc.) provides an alternative direct equivalent with identical current ratings and voltage specifications except for on-state voltage (5V vs. 4V). This 1V difference is within typical application tolerances for TVS thyristor circuits. ROHS3 compliance and active production status support long-term availability. Lower capacitance (50pF) compared to P2300SCLRP may provide improved high-frequency performance.

TB2300M-13-F (Diodes Incorporated) is a similar substitute suitable for applications where peak pulse current requirements do not exceed 250A (8/20µs) or 50A (10/1000µs). Breakover voltage is slightly elevated (265V vs. 260V) and on-state voltage is lower (4.6V). AEC-Q101 automotive qualification and ROHS3 compliance are provided. This part is appropriate for reduced-current transient suppression scenarios.

TISP4C250H3BJR-S (Bourns Inc.) is a similar substitute with 100A peak pulse current at 10/1000µs rating. Breakover voltage is lower (250V vs. 260V) and on-state voltage is lowest among alternatives (3V). REACH affected status requires compliance verification for regulated markets. Limited inventory (738 pcs) may impact procurement for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can P2300SCLRP directly replace NP2300SCMCT3G without circuit modification?

A: Yes. P2300SCLRP maintains identical off-state voltage (190V), breakover voltage (260V), on-state voltage (4V), and peak pulse current ratings (400A at 8/20µs, 100A at 10/1000µs). The DO-214AA SMB package and surface mount configuration are identical. Higher capacitance (80pF vs. 33pF) should be evaluated for circuits sensitive to high-frequency transient response.

Q: What is the difference between P2300SCLRP and P2300SCMCLRP?

A: Both parts are Littelfuse SIDACtor® TVS thyristors with identical current ratings and core voltage specifications. The primary difference is on-state voltage: P2300SCLRP is 4V while P2300SCMCLRP is 5V. Capacitance also differs: P2300SCLRP is 80pF and P2300SCMCLRP is 50pF. Selection depends on circuit requirements for on-state voltage drop and high-frequency performance.

Q: Can TB2300M-13-F be used in applications requiring 400A peak pulse current?

A: No. TB2300M-13-F is rated for 250A peak pulse current at 8/20µs, which is 150A below the NP2300SCMCT3G specification. This part is suitable only for applications with reduced transient current requirements. Exceeding the rated peak pulse current may cause component failure or degraded performance.

Q: Are all substitute parts RoHS compliant?

A: P2300SCLRP, P2300SCMCLRP, and TB2300M-13-F are ROHS3 compliant. TISP4C250H3BJR-S is ROHS3 compliant but has REACH affected status, requiring compliance verification for specific regulatory jurisdictions.

Q: What is the impact of capacitance variation among substitute parts?

A: Capacitance values range from 33pF (original) to 80pF (P2300SCLRP). Higher capacitance may slow transient response in high-frequency circuits but provides improved energy absorption for lower-frequency transients. Circuit simulation or testing is recommended for applications with strict transient response requirements.

Q: Is the NP2300SCMCT3G still available for procurement?

A: NP2300SCMCT3G is classified as obsolete. While 957 pcs are reported in stock, long-term availability is not assured. Active production alternatives (P2300SCLRP, P2300SCMCLRP, TB2300M-13-F, TISP4C250H3BJR-S) are recommended for new designs and ongoing procurement.
