NP2300SAT3G Equivalent & Substitute Parts

Part Overview

The NP2300SAT3G is a 190V off-state thyristor-based transient voltage suppressor (TVS) in DO-214AA surface mount packaging, manufactured by onsemi. This component is designed for transient overvoltage protection in electronic circuits with a peak pulse current rating of 50A (10/1000µs). The part is currently obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the NP2300SAT3G is determined by the following critical parameters:

• Voltage - Off State: Must be 190V to maintain equivalent circuit protection thresholds
• Voltage - Breakover: Must be 260V to ensure consistent triggering behavior
• Voltage - On State: Must be 4V for equivalent voltage drop characteristics
• Current - Hold (Ih): Must be 150mA for consistent holding current performance
• Package / Case: Must be DO-214AA, SMB for mechanical and thermal compatibility
• Mounting Type: Must be Surface Mount for PCB assembly compatibility
• Number of Elements: Must be 1 for single-channel protection

The substitute parts are grouped into two categories based on their alignment with these critical parameters:

Direct Substitutes (P2300S1ALRP): Meets all critical electrical and mechanical parameters with enhanced current handling capability.

Similar Substitutes (P2300SALRP, SMTPA200): Meet core voltage and package requirements with minor variations in secondary parameters such as capacitance and peak pulse current ratings at different pulse widths.

Parameter Comparison

Engineering Selection Recommendations

P2300S1ALRP (Littelfuse) is the primary direct substitute for NP2300SAT3G. This part maintains identical voltage specifications (190V off-state, 260V breakover) and holding current (150mA), with matching peak pulse current at 10/1000µs pulse width. The part is active in production status and RoHS3 compliant, ensuring long-term availability and regulatory compliance for new designs.

P2300SALRP (Littelfuse) is a secondary substitute with equivalent voltage and holding current specifications. The peak pulse current at 10/1000µs is rated at 45A compared to the original 50A specification. This part is active in production and RoHS3 compliant. REACH status is affected, requiring verification for applications subject to REACH regulations.

SMTPA200 (STMicroelectronics) is a similar substitute with a 200V off-state voltage specification, 10V higher than the original part. The breakover voltage is 267V, 7V higher than the original specification. This part is active in production and RoHS3 compliant. Selection of this part requires confirmation that the higher voltage thresholds are acceptable for the target application circuit.

Frequently Asked Questions (FAQ)

Q: Can P2300S1ALRP directly replace NP2300SAT3G without circuit modifications?

A: Yes. P2300S1ALRP maintains identical voltage specifications (190V off-state, 260V breakover), holding current (150mA), and peak pulse current (50A at 10/1000µs). The DO-214AA package and surface mount configuration are identical. No circuit modifications are required.

Q: What is the difference between P2300S1ALRP and P2300SALRP?

A: Both parts share identical voltage and holding current specifications. The primary difference is peak pulse current at 10/1000µs: P2300S1ALRP is rated at 50A while P2300SALRP is rated at 45A. Capacitance also differs slightly (50pF vs. 35pF). P2300SALRP has affected REACH status, while P2300S1ALRP is REACH unaffected.

Q: Why is SMTPA200 listed as a substitute if it has different voltage specifications?

A: SMTPA200 meets the core substitution criteria of DO-214AA package, surface mount configuration, and 150mA holding current. However, the 200V off-state and 267V breakover voltages differ from the original 190V and 260V specifications. This part is suitable only for applications where these higher voltage thresholds are acceptable.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts are available in DO-214AA, SMB surface mount packaging. P2300S1ALRP and P2300SALRP are supplied in Tape & Reel format. SMTPA200 is also supplied in Tape & Reel format. All parts are compatible with standard surface mount assembly processes.

Q: What is the impact of capacitance differences between substitute parts?

A: Capacitance values range from 25pF (SMTPA200) to 50pF (P2300S1ALRP). Capacitance affects high-frequency response and transient suppression characteristics. For applications sensitive to capacitive loading or high-frequency performance, capacitance differences should be evaluated against circuit requirements.

Q: Is RoHS compliance required for all substitute parts?

A: All three substitute parts are RoHS3 compliant. The original NP2300SAT3G RoHS status is not specified in the provided data. For applications requiring RoHS compliance, all listed substitutes meet this requirement.
