Product details
Overview
NP2300SCMCT3G from onsemi is a bidirectional ultra-low-capacitance thyristor surge protection device (TSPD) designed for telecom line protection in high-speed data interfaces. It features ±190 V repetitive peak off-state voltage (VDRM), ±260 V breakover voltage (V(BO)), 23 pF nominal off-state capacitance at 1 MHz, 4 V on-state voltage at 2.2 A peak, and 150 mA holding current - enabling low-distortion transient clamping in xDSL and T1/E1 circuits.
For engineers reviewing the NP2300SCMCT3G datasheet, pinout, applications, or equivalent options, key selection criteria include VDRM margin over system operating voltage, V(BO) alignment with protected circuit failure threshold, low Co for signal integrity, surge current rating compliance with GR-1089-CORE Category B (150 A pk), and SMB package compatibility with telecom PCB layouts.
Technical Context
The NP2300SCMCT3G operates as a crowbar-type protector: it remains high-impedance (open-circuit) during normal operation (IDRM ≤ 5 µA at VDRM), then switches to low-impedance (short-circuit) when transient voltage exceeds V(BO), shunting surge current to ground. Its bidirectional symmetry supports AC-coupled telecom lines without polarity constraints.
Thermal design relies on RθJA = 90°C/W (JEDEC FR4 3"×4.5", 2 oz copper), with junction temperature rated from −40°C to +150°C and storage range −65°C to +150°C. The device sustains non-repetitive peak impulse currents up to 150 A (2×10 µs waveform) per GR-1089-CORE Category A requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM | ±190 V - ensures reliable blocking of telecom line peak voltages including ring signals (≤212 V) and battery feed (≤48 V) without false triggering |
| V(BO) | ±260 V - defines maximum clamping voltage seen by protected circuitry; must be below SLIC or coupling capacitor breakdown thresholds |
| Co | 23 pF at 1 MHz, 2 Vdc - enables minimal signal distortion in broadband DSL/T1 applications up to ~30 MHz |
| VT | 4 V at 2.2 A pk - low on-state voltage allows efficient dissipation of 500 A-level surges within SMB package thermal limits |
| IH | 150 mA - holding current exceeds typical telecom line idle current (<10 mA), ensuring automatic recovery post-surge |
| IDRM | 5 µA at VDRM - ultra-low leakage preserves line impedance matching and reduces power loss in always-on systems |
| IPPS1 | 150 A pk (2×10 µs) - meets GR-1089-CORE Category A surge immunity for central office equipment |
Pinout & Package
NP2300SCMCT3G uses the SMB (DO-214AA, Case 403C) surface-mount package: 4.06–4.57 mm length, 3.30–3.81 mm width, 1.90–2.41 mm height, with gull-wing leads on 2.26 mm centerline spacing. The device is bidirectional and symmetrical; both terminals serve identical roles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (Terminals 1 & 2) | Bidirectional surge conduction path | Identical, interchangeable terminals - no polarity marking required; connects across differential telecom line (Tip/Ring) for common-mode and differential-mode protection |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low off-state capacitance | 23 pF enables <1% signal attenuation at 10 MHz in 100 Ω DSL lines, preserving eye diagram integrity |
| Pb-free, RoHS-compliant SMB package | Compatible with lead-free reflow profiles (J-STD-020) and telecom industry environmental mandates |
| Precise V(BO) tolerance | Guaranteed ±260 V breakover ensures consistent clamping across production lots and temperature (−40°C to +125°C) |
| Low voltage overshoot during turn-on | Clamps transients within 10 ns of exceeding V(BO), limiting peak stress on downstream SLIC or codec ICs |
| High surge current capability | 150 A (2×10 µs) rating supports multiple GR-1089-CORE Category A surges without degradation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional telecom surge protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NP2100SCMCT3G | VDRM = ±180 V, V(BO) = ±240 V - 10 V lower clamping voltage than NP2300SCMCT3G | Better suited for systems with tighter margin between operating voltage and protected IC failure threshold (e.g., low-voltage SLICs) | Select when VDRM ≥ 180 V suffices and lower V(BO) improves safety margin against downstream component breakdown |
| NP2600SCMCT3G | VDRM = ±220 V, V(BO) = ±300 V - 30 V higher clamping voltage, same 23 pF Co | Required where system peak voltage exceeds 190 V (e.g., legacy T1 with high ring voltage or long loop lengths) | Choose when VDRM headroom is needed beyond ±190 V, accepting higher clamping voltage for robustness under overvoltage stress |
Compared with NP2100SCMCT3G and NP2600SCMCT3G, the NP2300SCMCT3G offers optimal balance for modern xDSL infrastructure: sufficient VDRM margin over 48 Vdc + 150 Vrms ring (212 V peak), precise ±260 V clamping aligned with common SLIC ratings, and unchanged 23 pF capacitance for signal fidelity.

FAQ
What is the maximum continuous operating voltage for NP2300SCMCT3G?
The NP2300SCMCT3G has a repetitive peak off-state voltage (VDRM) of ±190 V, meaning it can continuously block up to 190 V peak in either polarity without triggering. This rating ensures safe operation in telecom systems with combined 48 Vdc battery feed and 150 Vrms ring voltage (212 V peak), provided design margin is maintained per onsemi's VDRM selection guidelines.
Does NP2300SCMCT3G require external bias or control circuitry?
No, the NP2300SCMCT3G is a passive, self-triggering thyristor surge protector with no external bias or control pins. It operates solely based on voltage across its terminals: remaining high-impedance below ±260 V (V(BO)) and switching to low-impedance conduction above that threshold. No drive circuitry, timing components, or power supply is needed.
How does NP2300SCMCT3G compare to standard TVS diodes in telecom applications?
Unlike unidirectional TVS diodes, the NP2300SCMCT3G provides symmetrical bidirectional clamping with ultra-low 23 pF capacitance - critical for maintaining signal integrity in AC-coupled DSL/T1 lines. Its thyristor-based crowbar action delivers lower clamping voltage overshoot and higher surge current handling (150 A vs. typical 10–60 A for TVS) without degrading over repeated events.
Is NP2300SCMCT3G compatible with lead-free reflow soldering processes?
Yes, the NP2300SCMCT3G is Pb-free and RoHS-compliant, qualified for standard lead-free reflow profiles per J-STD-020. Its SMB package withstands peak temperatures up to 260°C for 30 seconds, making it suitable for automated SMT assembly in telecom manufacturing environments without reliability risk.
What standards does NP2300SCMCT3G help satisfy for telecom equipment certification?
The NP2300SCMCT3G supports compliance with GR-1089-CORE (Categories A/B/C), ITU-T K.20/K.21/K.45, TIA-968-A, FCC Part 68, EN 60950, UL 1950, and IEC 61000-4-5. Its validated 150 A (2×10 µs) surge rating and precise ±260 V V(BO) enable direct use in certified telecom designs without additional derating or test correlation.
