NP2300SAMCT3G Equivalent & Substitute Parts

Part Overview

The NP2300SAMCT3G is a 190V off-state, 150A peak pulse (8/20µs) transient voltage suppressor 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 NP2300SAMCT3G functions as a TVS thyristor for transient voltage suppression applications requiring 190V off-state voltage rating and 150A peak pulse current handling capability. Substitute parts must maintain electrical compatibility across voltage ratings, current specifications, and mechanical packaging.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the NP2300SAMCT3G are classified into two functional groups based on electrical parameter compatibility:

Group 1: Direct Electrical Equivalents (150A Peak Pulse) Parts maintaining 190V off-state voltage and 150A peak pulse (8/20µs) current rating. These parts are functionally interchangeable with the original component.

Qualifying parts: P2300S1ALRP, P2300SALRP, TB2300L-13-F, SMTPA200

Group 2: Higher Current Capability (250A–400A Peak Pulse) Parts with 190V off-state voltage but elevated peak pulse current ratings (250A or 400A at 8/20µs). These parts provide enhanced transient suppression capability and are suitable for applications requiring higher current handling.

Qualifying parts: TB2300M-13-F, P2300SCMCLRP, TB2300H-13-F

All substitute parts maintain DO-214AA (SMB) surface mount packaging, single element configuration, 150mA hold current, and unlimited moisture sensitivity level (MSL 1). Voltage breakover ratings range from 260V to 267V, within acceptable tolerance for TVS thyristor applications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (150A Peak Pulse Applications)

P2300S1ALRP (Littelfuse) and TB2300L-13-F (Diodes Incorporated) are active production parts with electrical parameters matching the NP2300SAMCT3G. Both are RoHS3 compliant and carry unlimited moisture sensitivity level. P2300S1ALRP is available in higher inventory (1050 pcs) and maintains identical breakover voltage (260V). TB2300L-13-F offers slightly lower on-state voltage (4.6V vs 4V) and is available in 4200 pcs inventory.

P2300SALRP (Littelfuse) provides equivalent 150A peak pulse performance with REACH affected status, requiring compliance verification for regulated applications.

SMTPA200 (STMicroelectronics) maintains 150A peak pulse rating with 200V off-state voltage (10V higher than original specification). This part is suitable only for applications where the elevated off-state voltage does not conflict with circuit design parameters.

For Enhanced Current Capability (250A–400A Peak Pulse Applications)

TB2300M-13-F (Diodes Incorporated) provides 250A peak pulse capability with automotive grade qualification (AEC-Q101) and highest available inventory (20400 pcs). This part is suitable for designs requiring intermediate current handling between 150A and 400A specifications.

TB2300H-13-F and P2300SCMCLRP both provide 400A peak pulse capability for applications requiring maximum transient suppression. TB2300H-13-F offers lower on-state voltage (4.6V) and higher capacitance (80pF). P2300SCMCLRP provides 5V on-state voltage with 50pF capacitance.

All recommended active production parts carry RoHS3 compliance and REACH unaffected or affected status as specified. Selection should prioritize inventory availability, compliance requirements, and specific circuit voltage and current parameters.

Frequently Asked Questions (FAQ)

Q: Can P2300S1ALRP directly replace NP2300SAMCT3G in existing designs?

A: Yes. P2300S1ALRP maintains identical voltage ratings (190V off-state, 260V breakover), current specifications (150A peak pulse at 8/20µs, 50A at 10/1000µs), and hold current (150mA). Both use DO-214AA SMB surface mount packaging. Capacitance differs (50pF vs 23pF), which may affect high-frequency circuit behavior; verify circuit performance if capacitive loading is critical.

Q: What is the difference between Group 1 and Group 2 substitute parts?

A: Group 1 parts (P2300S1ALRP, P2300SALRP, TB2300L-13-F, SMTPA200) maintain 150A peak pulse (8/20µs) current rating, matching the original NP2300SAMCT3G specification. Group 2 parts (TB2300M-13-F, P2300SCMCLRP, TB2300H-13-F) provide higher peak pulse current ratings (250A or 400A), suitable for applications requiring enhanced transient suppression capability. Group 2 parts are not direct replacements but are compatible alternatives for designs tolerating higher current handling.

Q: Is SMTPA200 compatible with the original circuit design?

A: SMTPA200 maintains 150A peak pulse current and 150mA hold current specifications. However, off-state voltage is 200V (10V higher than NP2300SAMCT3G at 190V) and breakover voltage is 267V (7V higher than 260V). Verify that the circuit design tolerates these elevated voltage parameters before substitution.

Q: Which substitute part has the best inventory availability?

A: TB2300M-13-F (Diodes Incorporated) has the highest inventory at 20400 pcs. This part provides 250A peak pulse capability with automotive grade qualification (AEC-Q101). For 150A peak pulse applications, P2300SALRP offers 1400 pcs and TB2300L-13-F offers 4200 pcs.

Q: Are all substitute parts RoHS3 compliant?

A: All active production substitute parts listed carry RoHS3 compliance. The original NP2300SAMCT3G (obsolete) does not specify RoHS status. Verify RoHS compliance requirements for your application before final part selection.

Q: Can I use a higher current-rated part (400A) in place of the 150A original?

A: Yes, from an electrical compatibility standpoint. TB2300H-13-F and P2300SCMCLRP both maintain 190V off-state voltage and are packaged in DO-214AA SMB. However, higher current capability may introduce different transient response characteristics. Verify circuit performance and confirm that elevated capacitance (80pF for TB2300H-13-F, 50pF for P2300SCMCLRP) does not negatively affect circuit operation.

Q: What packaging options are available for substitute parts?

A: All substitute parts use DO-214AA (SMB) surface mount packaging, matching the original NP2300SAMCT3G. Tape & Reel (TR) packaging is standard for active production parts. No alternative package options are available among the listed substitutes.
