Product details
Overview
NP2600SC1T3G from onsemi is a bidirectional thyristor surge protector (TSPD) designed for overvoltage protection in telecom line interfaces. It features 220 V peak off-state voltage (VDRM), 300 V breakover voltage (VBO), 4.0 V on-state voltage (VT), 150 mA holding current (IH), and 800 A peak pulse surge current capability under 10×1000 µs waveform - deployed in central office, access network, and customer premises equipment.
For engineers reviewing the NP2600SC1T3G datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, SMB package layout, telecom-specific surge compliance (GR-1089-CORE, ITU-T K.20/21), and validated alternative parts for line interface protection design.
Technical Context
The NP2600SC1T3G operates as a crowbar-type bidirectional thyristor, triggering symmetrically in both polarities upon exceeding VBO = 300 V and latching until current falls below IH = 150 mA. Its low 4.0 V on-state voltage ensures minimal clamping loss during surge conduction.
It meets GR-1089-CORE Level C (100 A pk, 10×1000 µs) and ITU-T K.20 (75 A pk, 10×700 µs) requirements, with thermal resistance RθJA = 90 °C/W on FR4 PCB and operating junction temperature range of −40°C to +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM | 220 V - Maximum repetitive off-state voltage before conduction in either polarity; sets working voltage margin for 48 V/56 V telecom lines. |
| VBO | 300 V - Breakover voltage threshold at which device triggers into low-impedance state; defines minimum surge level required to activate crowbar action. |
| VT | 4.0 V - On-state voltage at 1.0 A peak current; determines power dissipation (4 W) and voltage drop across protected circuit during clamping. |
| IH | 150 mA - Minimum current needed to maintain conduction after triggering; ensures reliable latch-on during multi-cycle surges. |
| IPPS7 | 100 A (10×1000 µs) - Non-repetitive peak surge current rating per GR-1089-CORE; validates robustness against lightning-induced transients. |
| CO | 33 pF (1 MHz, 2 Vdc bias) - Junction capacitance; enables low signal distortion in high-speed telecom interfaces (e.g., xDSL, T1/E1). |
| TJ | −40°C to +150°C - Operating junction temperature range; supports deployment in uncontrolled environments like outdoor cabinets or DSLAMs. |
Pinout & Package
NP2600SC1T3G is housed in an SMB (DO-214AA, Case 403C) surface-mount package with two terminals: MT1 and MT2 - symmetrical bidirectional structure requiring no polarity assignment during placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MT1 | Anode/Cathode (bidirectional) | One main terminal; interchangeable with MT2 due to symmetrical thyristor construction; connects to line side of protected interface. |
| MT2 | Anode/Cathode (bidirectional) | Second main terminal; electrically identical to MT1; connects to ground or return path in telecom differential pair protection schemes. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional crowbar operation | Triggers and latches in both polarities without external biasing - eliminates need for dual-device discrete solutions in AC-coupled telecom lines. |
| Low 4.0 V on-state voltage | Minimizes power dissipation (<4 W at 1 A) and avoids overheating during sustained surge events, supporting repeated transient handling. |
| 33 pF typical capacitance | Preserves signal integrity in broadband applications (e.g., VDSL2 up to 30 MHz) without degrading insertion loss or return loss. |
| GR-1089-CORE Level C compliance | Validated for 100 A peak surge (10×1000 µs), meeting stringent central office equipment immunity requirements for lightning and power cross. |
| Pb-free, RoHS-compliant SMB package | Enables lead-free reflow assembly per JEDEC J-STD-020; footprint compatible with automated SMT lines using standard DO-214AA land patterns. |
Applications
| Central Office Line Card Protection | xDSL Interface Surge Suppression |

Equivalent & Alternatives
The following parts are listed as comparable options for similar thyristor surge protector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NP2600SAT3G | Same VDRM, VBO, and package; differs only in marking code (260A vs. 260C) and surge rating tier (Level A: 150 A pk, 2×10 µs). | Targeted at lower-energy surge environments (e.g., indoor CPE), not full GR-1089-CORE Level C. | Select NP2600SAT3G only when system-level testing confirms 150 A pk (2×10 µs) suffices and higher-tier surge immunity is unnecessary. |
| SM2600CT3G | Identical electrical specs and SMB package; manufactured by Littelfuse as second-source part with same VDRM/VBO/IH/CO. | Same telecom and industrial interface applications; qualified to identical GR-1089-CORE and ITU-T standards. | Use SM2600CT3G for supply chain diversification while maintaining full functional and mechanical equivalence to NP2600SC1T3G. |
Compared with NP2600SAT3G, NP2600SC1T3G delivers higher surge robustness (100 A vs. 150 A at different waveforms) for central office use, while SM2600CT3G offers identical performance with alternate sourcing - making NP2600SC1T3G optimal for Level C–compliant infrastructure where consistent qualification and traceability are critical.

FAQ
What is the peak off-state voltage rating of the NP2600SC1T3G?
The NP2600SC1T3G has a peak off-state voltage (VDRM) of 220 V, specified for both polarities. This rating defines the maximum repetitive voltage the device can block before triggering, making it suitable for telecom line interfaces operating up to 56 V nominal with safety margin. The value is measured at 25°C and confirmed per onsemi's NP0640S/D datasheet Rev. 5.
Does the NP2600SC1T3G require external triggering circuitry?
No, the NP2600SC1T3G is a self-triggering bidirectional thyristor surge protector. It activates automatically when voltage across MT1–MT2 exceeds its breakover voltage (VBO = 300 V) in either polarity, then latches until current drops below its holding current (IH = 150 mA). No gate drive or control signals are needed - the NP2600SC1T3G functions as a passive crowbar device.
Is the NP2600SC1T3G compliant with GR-1089-CORE Level C?
Yes, the NP2600SC1T3G is rated for 100 A peak surge current under the 10×1000 µs waveform per GR-1089-CORE Level C. This is documented in the "SURGE RATINGS" table of the official datasheet (NP0640S/D Rev. 5), confirming its suitability for central office equipment where highest immunity levels are mandated.
What is the thermal resistance of the NP2600SC1T3G in standard PCB layout?
The NP2600SC1T3G has a junction-to-ambient thermal resistance (RθJA) of 90 °C/W when mounted on a 3″×4.5″ FR4 PCB with 2 oz copper, per EIA/JESD51-3 test conditions. This value assumes a 3×3 inch fan-out pattern and directly informs thermal design margins for continuous surge duty cycles or ambient temperatures up to +70°C.
Can the NP2600SC1T3G be used in DC-powered interfaces like RS-485?
Yes, the NP2600SC1T3G is suitable for DC-powered interfaces including RS-485. Its 220 V VDRM provides ample margin above typical 5 V, 12 V, or 24 V bus voltages, and its bidirectional symmetry allows placement across differential pairs without polarity concerns. It has been validated in industrial Ethernet port designs meeting IEC 61000-4-5 Level 4.
