Product details
Overview
NP2600SAMCT3G 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 low-signal-distortion transient clamping in high-speed data lines.
For engineers reviewing the NP2600SAMCT3G datasheet, pinout, applications, or equivalent options, this device is selected for precise overvoltage threshold control, fail-safe crowbar action, compliance with GR-1089-CORE and ITU-T K.20/K.21, and minimal capacitive loading in differential telecom pairs.
Technical Context
The NP2600SAMCT3G operates as a bidirectional crowbar-type protector: it remains high-impedance (open-circuit) under normal operation (IDRM ≤ 5 µA at VDRM), then switches to low-impedance conduction when transient voltage exceeds V(BO), shunting surge current to ground. Its ultra-low 23 pF off-state capacitance ensures signal integrity up to multi-MHz frequencies in DSL/T1 lines.
It supports non-repetitive surge currents up to 150 A (2×10 µs waveform), withstands ±500 A/µs di/dt, and maintains thermal stability with RθJA = 90 °C/W. Junction temperature range is −40 °C to +150 °C, and storage extends to −65 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM | ±220 V - maximum continuous line voltage the device blocks without triggering, ensuring transparency during 48 V DC + 150 V RMS ring voltage (212 V peak) operation |
| V(BO) | ±300 V - guaranteed maximum clamping voltage seen by protected circuitry, set below equipment failure thresholds like SLIC or coupling capacitor ratings |
| Co | 23 pF - ultra-low off-state capacitance at 1.0 MHz/2 Vdc bias, minimizing insertion loss and phase distortion in broadband DSL/T1 signals |
| VT | 4 V - low on-state voltage at 2.2 A peak, enabling efficient surge energy dissipation without excessive I²R heating in SMB package |
| IH | 150 mA - minimum current required to sustain conduction; must exceed system fault-hold current to avoid latch-up after surge clearance |
| IDRM | 5 µA at VDRM - negligible leakage ensures no DC loading or bias shift in protected analog/digital line interfaces |
| IPPS1 | 150 A (2×10 µs) - non-repetitive surge current rating defining robustness against lightning-induced transients per GR-1089-CORE Class A |
Pinout & Package
NP2600SAMCT3G uses the SMB (DO-214AA, Case 403C) surface-mount package - a bidirectional two-terminal device with no polarity marking; both terminals are electrically symmetric and interchangeable in circuit layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (Terminals 1 & 2) | Bidirectional surge path | Identical terminals; either may connect to tip or ring in telecom line - enables symmetrical clamping of positive/negative transients without orientation constraints |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low off-state capacitance | 23 pF ensures <0.5% signal attenuation at 2.2 MHz (xDSL upstream band), preserving bit-error-rate performance |
| Pb-free, RoHS-compliant packaging | SMB (DO-214AA) case meets JEDEC standards and supports lead-free reflow profiles up to 260 °C peak |
| Precise bidirectional breakover | ±300 V V(BO) tolerance ≤ ±5% guarantees consistent clamping across production lots and temperature (−40 °C to +125 °C) |
| Low leakage transparency | IDRM ≤ 5 µA at ±220 V prevents DC offset drift or false triggering in high-impedance line monitoring circuits |
| Crowbar fail-safe operation | Self-resetting behavior after surge decay avoids permanent short; worst-case latch-up is safe (no fire hazard) per UL 1950 |
Applications
| ADSL Central Office Line Card | T1/E1 Data Interface Protection |
|---|---|
Use Scenario: Protecting copper pair inputs on DSLAM line cards exposed to induced lightning surges and power-cross events in telco central offices. IC Role / Device Role / Timing Role: Bidirectional crowbar protector placed across tip/ring before line driver/receiver ICs to clamp transients before they reach sensitive analog front-end circuitry. Use Value: 23 pF capacitance prevents degradation of ADSL2+ upstream SNR; ±300 V V(BO) ensures clamping occurs below SLIC IC breakdown (typically ±330 V). | Use Scenario: Safeguarding T1/E1 framer and transformer-coupled interface circuits in enterprise PBX and channel bank equipment. IC Role / Device Role / Timing Role: Primary overvoltage shunt mounted directly at connector entry point, operating in open-circuit state during 1.544/2.048 Mbps NRZ signaling. Use Value: 150 A (2×10 µs) surge rating meets GR-1089-CORE Class A requirements; low VT minimizes voltage overshoot during fast-rising transients. |
| xDSL Customer Premises Equipment | Broadband Access Gateway Protection |
Use Scenario: Integrated into residential DSL modems and gateways to protect internal PHY and splitter circuits from customer-side surges. IC Role / Device Role / Timing Role: Secondary protection stage downstream of gas discharge tube (GDT), providing low-capacitance fine clamping after coarse GDT diversion. Use Value: SMB footprint allows compact placement near RJ-11 jack; ±220 V VDRM accommodates 48 V battery backup + ringing voltage margins. | Use Scenario: Securing multi-service access gateways handling voice, data, and video over shared copper infrastructure. IC Role / Device Role / Timing Role: Dual-device configuration (one per line pair) in differential mode, maintaining impedance balance while suppressing common-mode surges. Use Value: Matched V(BO) symmetry (<±2 V deviation between terminals) preserves differential signal integrity during asymmetric surge events. |
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 |
|---|---|---|---|
| NP2300SAMCT3G | VDRM = ±190 V, V(BO) = ±260 V - lower clamping threshold and reduced voltage margin | Better suited for systems with tighter operating voltage headroom (e.g., 24 V DC + 100 V RMS ring) | Select when VDRM margin above system peak voltage is <30 V; verify V(BO) remains below protected IC's absolute max rating. |
| NP3100SAMCT3G | VDRM = ±275 V, V(BO) = ±350 V - higher blocking and clamping voltages | Required where line voltage includes extended ringing (e.g., 170 V RMS) or legacy PBX compatibility | Choose for new deployments targeting GR-1089-CORE Class B/C surge levels or future-proofing against higher-voltage standards. |
Compared with NP2300SAMCT3G and NP3100SAMCT3G, the NP2600SAMCT3G provides optimal voltage margin for standard 48 V DC + 150 V RMS telecom lines - balancing sufficient VDRM headroom (≥260 V peak) against conservative V(BO) to avoid overstressing downstream components.

FAQ
What is the maximum continuous operating voltage for NP2600SAMCT3G?
The NP2600SAMCT3G has a repetitive peak off-state voltage (VDRM) of ±220 V, meaning it reliably blocks up to ±220 V DC or peak AC voltage during normal operation. This rating ensures transparency in telecom systems with 48 V DC battery backup and 150 V RMS ringing voltage (212 V peak), providing ≥8 V safety margin above worst-case line voltage.
Does NP2600SAMCT3G require external bias or control circuitry?
No, NP2600SAMCT3G is a passive, two-terminal device with no control pins or bias requirements. It operates autonomously: remaining high-impedance until line voltage exceeds ±300 V (V(BO)), then switching to low-impedance conduction to shunt surge current. No drivers, timers, or enable signals are needed - simplifying PCB layout and reducing BOM count.
How does NP2600SAMCT3G compare to TVS diodes for telecom protection?
Unlike unidirectional TVS diodes, NP2600SAMCT3G offers symmetrical bidirectional clamping with identical ±300 V V(BO) and only 23 pF capacitance - critical for balanced DSL/T1 pairs. Its crowbar action delivers lower dynamic impedance during surge than avalanche TVS, resulting in less voltage overshoot. Also, its 150 A (2×10 µs) rating exceeds most telecom-grade TVS devices in the same SMB package.
Is NP2600SAMCT3G compliant with GR-1089-CORE and ITU-T K.20?
Yes, NP2600SAMCT3G is explicitly validated for GR-1089-CORE (Class A: 150 A, 2×10 µs) and ITU-T K.20/K.21/K.45 surge immunity standards. Its electrical parameters - including VDRM, V(BO), IPPS, and Co - were designed and tested to meet these requirements, and it is listed as a recognized component per UL 1950 and EN 60950 safety standards.
What is the thermal resistance and maximum junction temperature of NP2600SAMCT3G?
NP2600SAMCT3G has a junction-to-ambient thermal resistance (RθJA) of 90 °C/W under JEDEC-standard PCB conditions (FR4, 2 oz copper, 3×3 inch pad). Its maximum rated junction temperature is +150 °C, with operational range from −40 °C to +150 °C - supporting deployment in uncontrolled telco cabinets and outdoor DSLAM enclosures.
