Product details
Overview
NP2300SCT3G from onsemi is a bidirectional thyristor surge protector (TSPD) designed for overvoltage protection in telecom line interfaces. It features 190 V peak off-state voltage (VDRM), 260 V breakover voltage (VBO), 4.0 V on-state voltage (VT), 150 mA holding current (IH), and supports 500 A(pk) 10×1000 µs surge current per GR-1089-CORE. It is used in central office and customer premises equipment to meet IEC 61000-4-5 and ITU-T K.20/21 compliance.
For engineers reviewing the NP2300SCT3G datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, SMB package dimensions, surge rating context, thermal limits, and direct alternatives for telecom-grade transient protection design.
Technical Context
The NP2300SCT3G operates as a voltage-triggered crowbar device: it remains high-impedance below VDRM (190 V), switches to low-impedance conduction at VBO (260 V), and latches until current falls below IH (150 mA). Its bidirectional symmetry enables single-device protection of AC-coupled lines without polarity concerns.
It sustains repetitive surges per TIA-968-A (10×160 µs, 90 A) and GR-1089-CORE (10×1000 µs, 50 A), with dv/dt immunity ≥5 kV/s and di/dt capability up to 500 A/s. Thermal resistance is 90 °C/W (Junction-to-Ambient, FR4 3″×4.5″, 2 oz copper).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM | 190 V - Maximum continuous off-state voltage before conduction in either polarity |
| VBO | 260 V - Voltage threshold at which device triggers into low-impedance state under surge |
| VT | 4.0 V - On-state voltage drop at 1.0 A peak, defining clamping loss during conduction |
| IH | 150 mA - Minimum current required to maintain conduction after triggering |

| CO | 36 pF - Typical capacitance at 1 MHz, 1 Vrms, 2 Vdc bias - critical for signal integrity in high-speed lines |
| TJ | −40 to +150 °C - Operating junction temperature range, supporting industrial telecom environments |
Pinout & Package
NP2300SCT3G is housed in an SMB (DO-214AA, Case 403C) surface-mount package with two terminals: MT1 and MT2. The device is symmetrical and bidirectional; neither terminal is designated anode or cathode. Marking "230C" appears on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MT1 | Main Terminal 1 | One of two identical, interchangeable main current terminals; no polarity assignment |
| MT2 | Main Terminal 2 | Second identical main terminal; device conducts equally in both directions between MT1 and MT2 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar thyristor surge protector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NP2300SAT3G | Same VDRM/VBO/IH, but rated for 75 A(pk) 10×360 µs (vs. 50 A for NP2300SCT3G); higher surge category | Suitable for equipment requiring GR-1089-CORE Level 2 (not Level 3) or TIA-968-A Category B | Select when higher short-duration surge margin is needed without changing layout or thermal design |
| NP2300SBT3G | Identical electrical specs and package; differs only in marking ("230B") and internal lot traceability | No functional or application difference; same qualification, reliability, and compliance data | Use when sourcing from alternate production lots or distributors with B-suffix inventory |
Compared with NP2300SAT3G and NP2300SBT3G, the NP2300SCT3G offers optimized cost and availability for Level 3 GR-1089-CORE deployments where 50 A (10×1000 µs) surge handling is sufficient, with identical mounting and thermal behavior.

FAQ
What is the maximum continuous operating voltage for NP2300SCT3G?
The NP2300SCT3G has a peak off-state voltage (VDRM) of 190 V, meaning it can safely block up to 190 V DC or peak AC voltage in either polarity without triggering. This rating applies at TJ = 25°C and derates slightly at elevated temperatures; full derating curves are provided in the official onsemi NP0640S/D datasheet.
Does NP2300SCT3G require a gate trigger signal?
No, the NP2300SCT3G is a gateless, voltage-triggered thyristor. It switches automatically when voltage across MT1–MT2 exceeds its breakover voltage (VBO = 260 V) - no external control signal, bias, or gate circuitry is needed. Its operation is purely passive and self-protecting.
Can NP2300SCT3G be used in DC power line protection?
Yes, NP2300SCT3G is bidirectional and functions identically on DC lines: it blocks up to 190 V and triggers at 260 V transient peaks. However, because it latches on until current falls below 150 mA, ensure the protected circuit has natural current interruption (e.g., via fuse, PTC, or load disconnection) to enable automatic reset.
What is the thermal resistance of NP2300SCT3G in standard PCB layout?
The NP2300SCT3G has a junction-to-ambient thermal resistance (RθJA) of 90 °C/W when mounted on a FR4 PCB measuring 3″ × 4.5″ with 2 oz copper, using a 3×3 inch fan-out pattern. This value assumes no additional heatsinking; actual thermal performance depends on copper area, layer count, and airflow.
Is NP2300SCT3G compliant with RoHS and REACH?
Yes, NP2300SCT3G is marked with "G" per onsemi's ordering nomenclature, indicating Pb-free (RoHS-compliant) construction. It meets EU RoHS Directive 2011/65/EU and REACH SVHC requirements. Full material declarations and test reports are available through onsemi's product compliance portal.
