Product details
Overview
SMP100MC-360 from STMicroelectronics is a bidirectional thyristor surge suppressor (TSS) designed for fail-safe overvoltage protection on high-speed data lines. It features a 360 V breakover voltage (VBO), 15 pF typical capacitance at 50 V, 2 μA max leakage current, 150 mA minimum holding current, and 100 A repetitive peak pulse current (10/1000 μs). It is deployed in ADSL2+ line cards and telecom central office interfaces requiring low-distortion transient suppression.
For engineers reviewing the SMP100MC-360 datasheet, SMP100MC-360 pinout, SMP100MC-360 application, or SMP100MC-360 equivalent, this device serves as a micro-capacitance crowbar protector meeting GR-1089 Core, ITU-T K20/K21, IEC 61000-4-5, and UL497B requirements - critical for telecom surge compliance and signal integrity in xDSL systems.
Technical Context
The SMP100MC-360 operates as a bidirectional silicon-controlled rectifier (SCR) that latches into low-impedance conduction upon exceeding its dynamic breakover voltage (VBO = 360 V), clamping transients while maintaining <15 pF capacitance to preserve signal integrity up to 30 MHz. Its fail-safe short-circuit mode ensures equipment protection even after multiple surges.
It sustains 100 A (10/1000 μs) repetitive pulses and meets IEC 61000-4-2 Level 4 ESD immunity (15 kV air/8 kV contact), with thermal resistance Rth(j-a) = 100 °C/W and operating junction temperature range of –40 °C to +150 °C - enabling robust deployment in uncontrolled industrial and telco environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBO (Dynamic) | 360 V - triggers crowbar action at defined overvoltage threshold without delay or degradation |
| C (at 50 V, 1 MHz) | 15 pF - minimizes signal distortion on ADSL2+/VDSL data lines up to 30 MHz |
| IPP (10/1000 μs) | 100 A - handles repeated lightning-induced surges per GR-1089 Core first-level requirements |
| IR (max at VRM) | 2 μA - ensures negligible standby power loss and no false triggering under normal operation |
| IH (min) | 150 mA - guarantees reliable latching and sustained conduction during surge events |

Equivalent & Alternatives
The following parts are listed as comparable options for similar thyristor surge suppressor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMCJ36CA | Unidirectional TVS diode; 36 V standoff, 58.1 V clamping, 1500 W peak power; no latching behavior | Lacks fail-safe short-circuit mode; requires series impedance for current limiting; higher capacitance (~300 pF) | Use only where crowbar action is unnecessary and lower-cost transient clamping suffices |
| TISP4240M3BJR-S | Bidirectional TSS; 240 V VBO, 100 A IPP, 20 pF; smaller SOD-123FL package, lower thermal mass | Lower VBO limits use to sub-240 V AC-coupled lines; not rated for GR-1089 Core Level 1 | Select when space-constrained designs require 240 V protection and GR-1089 second-level compliance is sufficient |
Compared with SMCJ36CA and TISP4240M3BJR-S, the SMP100MC-360 uniquely combines 360 V VBO, 15 pF capacitance, and fail-safe short-circuit behavior - making it the only option qualified for GR-1089 Core Level 1 and ITU-T K20/K21 in high-data-rate telecom line cards.

FAQ
What is the fail-safe behavior of SMP100MC-360 during end-of-life?
Upon reaching end-of-life after repeated surge events, the SMP100MC-360 enters a permanent short-circuit state - maintaining low-impedance conduction and continuing to protect downstream circuitry. This fail-safe mode prevents open-circuit failure, which could leave equipment vulnerable to subsequent surges.
Can SMP100MC-360 be used on Ethernet (10/100BASE-T) lines?
No - SMP100MC-360 is not recommended for Ethernet. Its 360 V VBO exceeds typical Ethernet common-mode surge thresholds (e.g., 1.5 kV per IEC 61000-4-5), and its 150 mA holding current may disrupt PHY auto-negotiation or cause latch-up in magnetics-coupled interfaces. Use dedicated Ethernet ESD arrays instead.
How does SMP100MC-360 differ from standard TVS diodes in surge response?
Unlike TVS diodes that clamp with voltage-dependent leakage and degrade over time, the SMP100MC-360 uses thyristor-based crowbar action: it switches abruptly to low-impedance conduction at VBO, sustains conduction until current falls below IH, and exhibits no wear-out mechanism - delivering consistent performance across thousands of surges.
Is SMB (DO-214AA) footprint compatible with industry-standard reflow profiles?
Yes - the SMB package supports standard lead-free reflow profiles (peak 260 °C for 10 s), with thermal resistance Rth(j-l) = 20 °C/W and Rth(j-a) = 100 °C/W using ST-recommended PCB footprint. Its UL94 V0 epoxy and halogen-free resin comply with IPC-J-STD-020D moisture sensitivity level 1.
