Product details
Overview
NP2600SCMCT3G 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 ±220 V repetitive peak off-state voltage (VDRM), ±300 V breakover voltage (V(BO)), 23 pF nominal off-state capacitance at 1 MHz, 4 V on-state voltage at 2.2 A, and 150 mA holding current - enabling low-distortion transient clamping in xDSL and T1/E1 circuits.
For engineers reviewing the NP2600SCMCT3G datasheet, pinout, applications, or equivalent options, key selection criteria include VDRM margin above system operating voltage, V(BO) alignment below protected circuit failure threshold, low Co for signal integrity, compliance with GR-1089-CORE and ITU-T K.20/K.21, and SMB package suitability for telecom PCB layouts.
Technical Context
The NP2600SCMCT3G 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 concerns.
It delivers non-repetitive peak impulse current ratings of 150 A (2×10 µs), 250 A (8×20 µs), and 500 A (10×1000 µs), with thermal resistance RθJA = 90 °C/W and junction temperature range −40 °C to +150 °C - supporting robust surge handling in uncontrolled ambient environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM | ±220 V - ensures transparency under worst-case telecom line peaks (e.g., 48 V DC + 150 V RMS ring voltage ≈ 260 V peak) |
| V(BO) | ±300 V - defines maximum clamped voltage seen by protected circuitry (e.g., SLIC or coupling capacitor) |
| Co | 23 pF @ 1 MHz - preserves signal integrity in >10 Mbps DSL/T1 applications with minimal insertion loss |
| VT | 4 V @ 2.2 A - enables efficient surge conduction with low power dissipation in compact SMB footprint |
| IH | 150 mA - prevents latch-up after surge decay; must exceed system's steady-state current to auto-reset |
| IDRM | 5 µA @ VDRM - guarantees near-zero leakage during normal operation, avoiding false triggering |

FAQ
What is the maximum continuous operating voltage for NP2600SCMCT3G?
The NP2600SCMCT3G has a repetitive peak off-state voltage (VDRM) of ±220 V, meaning it can safely withstand continuous AC or DC voltages up to 220 V peak in either polarity without triggering. This rating ensures reliable transparency during normal operation in telecom circuits with 48 V DC bias plus 150 V RMS ringing voltage (≈260 V peak), provided design margins are applied per onsemi's selection guidelines.
Does NP2600SCMCT3G require external bias or control circuitry?
No, the NP2600SCMCT3G is a passive, self-triggering thyristor surge protection device. It requires no external power, bias voltage, or control signals. The device automatically switches from high-impedance (open-circuit) to low-impedance (crowbar) state when line voltage exceeds its ±300 V breakover voltage (V(BO)), then resets to open-circuit once current falls below its 150 mA holding current (IH).
How does NP2600SCMCT3G compare to standard TVS diodes in telecom applications?
Unlike unidirectional TVS diodes, the NP2600SCMCT3G offers symmetrical bidirectional clamping with ultra-low 23 pF capacitance - critical for AC-coupled DSL/T1 lines where signal integrity above 1 MHz is essential. Its thyristor structure provides lower clamping voltage under high-current surges (4 V vs. >10 V for many TVS) and inherent fail-safe short-circuit behavior compliant with GR-1089-CORE.
What is the thermal performance of NP2600SCMCT3G in sustained surge conditions?
The NP2600SCMCT3G has a junction-to-ambient thermal resistance (RθJA) of 90 °C/W on a standard FR4 PCB (3″×4.5″, 2 oz copper). While rated for non-repetitive surges only, its 4 V on-state voltage limits power dissipation during 500 A events, and its −40 °C to +150 °C operating range ensures functionality in unventilated telecom enclosures. For repetitive surges, derating per onsemi's application notes is required.
Is NP2600SCMCT3G compatible with lead-free reflow soldering processes?
Yes, the NP2600SCMCT3G is Pb-free and RoHS-compliant (indicated by the "G" suffix), qualified for standard lead-free reflow profiles with peak temperatures up to 260 °C. Its SMB (DO-214AA) package is fully compatible with automated SMT assembly lines used in telecom module manufacturing, and onsemi provides detailed soldering recommendations in their Soldering and Mounting Techniques Reference Manual.
