Product details
Overview
NP2600SBMCT3G from onsemi is a bidirectional ultra-low-capacitance thyristor surge protection device (TSPD) designed for telecom line protection in xDSL and T1/E1 interfaces. It features ±220 V repetitive peak off-state voltage (VDRM), ±300 V breakover voltage (V(BO)), 23 pF nominal off-state capacitance at 1.0 MHz, 4 V on-state voltage at 2.2 A, and 150 mA holding current - enabling transparent operation and fast crowbar clamping in high-speed data lines.
For engineers reviewing the NP2600SBMCT3G datasheet, pinout, applications, or equivalent options, this device is selected for precise overvoltage threshold control, minimal signal distortion in broadband transmission, compliance with GR-1089-CORE and ITU-T K.20/K.21, and robust 150 A non-repetitive surge current handling per 10×160 µs waveform.
Technical Context
The NP2600SBMCT3G operates as a bidirectional crowbar-type protector: it remains high-impedance (open-circuit) under normal operating conditions up to ±220 V, then switches rapidly to low-impedance (short-circuit) when transient voltage exceeds ±300 V, shunting surge energy to ground. Its 23 pF off-state capacitance ensures linearity and minimal insertion loss up to 100 MHz.
It complies with multiple telecom surge standards including GR-1089-CORE (2×10 µs, 10×360 µs), TIA-968-A (10×160 µs), and ITU-T K.20/K.21 (10×700 µs), supporting Class B and C surge ratings up to 150 A (A), 250 A (B), and 500 A (C) depending on waveform. Thermal resistance is 90 °C/W (Junction-to-Ambient).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM | ±220 V - maximum continuous AC/DC voltage before conduction; ensures transparency across 48 V DC + 150 V RMS ring voltage systems |
| V(BO) | ±300 V - guaranteed maximum clamping voltage during surge; protects downstream SLIC and coupling capacitors rated ≤300 V |
| Co | 23 pF @ 1.0 MHz, 1.0 Vrms, 2 Vdc - ultra-low capacitance preserves signal integrity in ADSL/T1/E1 data paths |
| VT | 4 V @ 2.2 A pk, 300 µs pulse - low on-state voltage enables efficient surge dissipation without excessive power loss |
| IH | 150 mA - minimum current to sustain conduction; must exceed system fault-hold current to avoid latch-up |
| IDRM | 5 µA @ VDRM - ultra-low leakage ensures no loading of live telecom lines during standby |
| IPPS (10×160 µs) | 150 A (Class A), 250 A (Class B), 500 A (Class C) - defines surge current capability per industry-standard waveform |
Pinout & Package
NP2600SBMCT3G is housed in an SMB (DO-214AA, Case 403C) surface-mount package with two terminals: Anode and Cathode arranged in a symmetrical bidirectional configuration. The device has no polarity marking; either terminal may serve as input or output in AC line applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Surge current entry point during positive half-cycle | Connects to protected line (e.g., Tip or Ring); forms bidirectional crowbar path with Cathode |
| Cathode (K) | Surge current entry point during negative half-cycle | Connects to protected line opposite Anode; completes symmetrical clamping path to ground reference |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low off-state capacitance | 23 pF - preserves high-frequency signal fidelity in xDSL (>12 MHz) and T1/E1 (1.5–2.048 MHz) links |
| Precise bidirectional breakover voltage | ±300 V - tightly controlled threshold ensures consistent protection margin across both polarities |
| Low leakage current | 5 µA max @ VDRM - eliminates line loading and avoids false triggering in low-power telecom circuits |
| High surge current rating | 500 A (10×700 µs) - meets GR-1089-CORE Category C requirements for central office equipment |
| Pb-free, RoHS-compliant packaging | SMB (DO-214AA) with matte tin lead finish - compatible with standard reflow profiles and IPC-J-STD-020 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional thyristor surge protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NP2600SCMC | Same electrical specs, but in SMC (DO-214AB) package - 5.3 mm × 4.6 mm vs. SMB's 4.6 mm × 3.9 mm | Higher thermal mass and 2× higher IPPS rating (1000 A vs. 500 A for 10×700 µs); suited for central office vs. CPE | Select NP2600SCMC when board space allows and higher surge endurance is required; not drop-in due to footprint change |
| SM15T22CA | TVS diode array (not thyristor); 22 V working voltage, 36.5 V VBR, 1500 W peak power - fundamentally different clamping mechanism | Limited to low-voltage data lines; cannot replace NP2600SBMCT3G in 48 V+ telecom applications due to VDRM mismatch | Only consider SM15T22CA for secondary protection downstream of TSPD; not a functional alternative for primary line protection |
Compared with NP2600SCMC, NP2600SBMCT3G offers identical surge thresholds but reduced footprint and thermal mass - ideal for space-constrained CPE designs. Versus SM15T22CA, it provides true bidirectional crowbar action at telecom-grade voltages, whereas the TVS lacks holding current and fails open under sustained overvoltage.

FAQ
What is the maximum continuous operating voltage for NP2600SBMCT3G?
The NP2600SBMCT3G has a repetitive peak off-state voltage (VDRM) of ±220 V. This means it can safely withstand continuous AC or DC voltages up to ±220 V in the off-state without triggering. It is designed for telecom systems where combined DC battery feed (e.g., 48 V) and AC ring voltage (e.g., 150 V RMS = ~212 V peak) require a minimum VDRM >260 V - so NP2600SBMCT3G is typically used in lower-tier CPE applications or with additional series impedance.
Does NP2600SBMCT3G have polarity-sensitive mounting?
No, NP2600SBMCT3G is a fully bidirectional thyristor device with symmetrical Anode and Cathode terminals. Either terminal may be connected to Tip or Ring in telecom line applications. The SMB package has no polarity marking, and the device functions identically regardless of orientation - a key advantage for protecting AC-coupled differential pairs like T1/E1 or xDSL.
How does NP2600SBMCT3G differ from standard TVS diodes in surge protection?
Unlike unidirectional or bidirectional TVS diodes that clamp with avalanche breakdown, NP2600SBMCT3G uses thyristor-based crowbar action: it latches into a low-voltage on-state (4 V) once triggered and holds until current falls below 150 mA. This provides lower let-through voltage and superior energy handling for long-duration surges (e.g., 10×700 µs), but requires careful IH matching to avoid unintended latch-up - a distinction critical in telecom loop-powered systems.
What is the off-state capacitance of NP2600SBMCT3G and why does it matter?
NP2600SBMCT3G has a nominal off-state capacitance (Co) of 23 pF measured at 1.0 MHz, 1.0 Vrms, and 2 Vdc bias. This ultra-low value minimizes signal attenuation and phase distortion in high-speed data lines - essential for maintaining ADSL2+ upstream bandwidth (>12 MHz) and T1/E1 timing integrity. Capacitance remains stable across voltage (Figure 4), ensuring linear performance up to 50 V bias.
Which regulatory standards does NP2600SBMCT3G help satisfy?
NP2600SBMCT3G supports compliance with GR-1089-CORE (including 2×10 µs, 10×360 µs waveforms), ITU-T K.20/K.21/K.45, TIA-968-A, FCC Part 68, UL 1950, EN 60950, and IEC 61000-4-5. Its specified surge ratings - e.g., 500 A for 10×700 µs - directly map to Category C test levels in GR-1089-CORE, making it suitable for both customer premises and edge network equipment.
