Product details
Overview
SMP100MC-200 from STMicroelectronics is a bidirectional thyristor surge suppressor (TSS) designed for fail-safe overvoltage protection on high-speed data lines. It features a 200 V breakover voltage (VBO), 15–20 pF capacitance at 50 V, ≤2 μA leakage current, 150 mA minimum holding current (IH), and 100 A repetitive peak pulse current (10/1000 μs). It is deployed in ADSL2+ line cards to prevent signal distortion during lightning-induced surges.
For engineers reviewing the SMP100MC-200 datasheet, SMP100MC-200 pinout, SMP100MC-200 application, or SMP100MC-200 equivalent, this device delivers verified crowbar action with micro-capacitance, JEDEC DO-214AA (SMB) packaging, UL497B recognition, and compliance with IEC 61000-4-5, ITU-T K20/K21, and GR-1089 Core standards - critical for telecom front-end surge protection design.
Technical Context
The SMP100MC-200 operates as a voltage-triggered bidirectional crowbar device: it remains high-impedance until reverse or forward voltage exceeds its 200 V static VBO, then latches into low-impedance conduction until current falls below 150 mA IH. Its 20 pF capacitance at 50 V ensures minimal loading on 1–30 MHz DSL signals.
It meets fail-safe short-circuit behavior per IEC 61000-4-5 Level 4 and GR-1089 Core first-level surge requirements (2500 V / 100 A, 10/1000 μs), with thermal resistance Rth(j-a) = 100 °C/W and junction temperature range of –40 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBO (Static) | 200 V - precise trigger threshold for AC line fault and lightning surge clamping |
| C (at 50 V) | 20 pF - preserves signal integrity on ADSL2+/VDSL data lines up to 30 MHz |
| IPP (10/1000 μs) | 100 A - sustains repeated telecom-grade surge events without degradation |
| IR (max) | 2 μA - negligible standby power loss and no false triggering in low-power systems |
| IH (min) | 150 mA - ensures reliable latch-off only after surge energy dissipates fully |
| Package | DO-214AA (SMB) - JEDEC-standard surface-mount footprint with 5.1–5.6 mm body width |
| Standards | UL497B recognized, IEC 61000-4-5, ITU-T K20/K21, GR-1089 Core - certified for telecom infrastructure |

| Low leakage (≤2 μA) | Eliminates DC bias shift in analog front-ends and avoids false triggers in high-impedance receivers |
| JEDEC DO-214AA compatibility | Direct drop-in replacement for industry-standard SMB footprint; supports automated SMT assembly |
Applications
| ADSL2+ Line Card Protection | VDSL2 Central Office Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar thyristor surge suppressor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMCJ200A | Unidirectional TVS diode; 200 V standoff; 100 A (8/20 μs); 150 pF capacitance | Lacks fail-safe short-circuit behavior; higher capacitance degrades >5 MHz signals | Use only where crowbar action is not required and lower-frequency protection suffices |
| P6KE200A | Unidirectional glass-passivated TVS; 200 V VBR; 100 A (8/20 μs); ~200 pF | No latching; no fail-safe mode; unsuitable for telecom line-card reliability requirements | Acceptable for cost-sensitive non-certified consumer electronics, not telecom infrastructure |
Compared with SMCJ200A and P6KE200A, the SMP100MC-200 uniquely combines bidirectional crowbar action, sub-30 pF capacitance, and UL497B-recognized fail-safe operation - making it the only qualified solution for GR-1089-compliant DSL line protection.

FAQ
What is the fail-safe behavior of SMP100MC-200 during a catastrophic surge?
The SMP100MC-200 enters permanent short-circuit (fail-safe) mode when subjected to non-repetitive surge currents exceeding its IFS rating (5 kA, 8/20 μs). This ensures downstream circuitry remains protected even after device degradation, unlike TVS diodes that may fail open-circuit. The short-circuit state is irreversible and requires replacement.
Can SMP100MC-200 be used on Ethernet (100BASE-TX) lines?
No - SMP100MC-200 is not recommended for Ethernet. Its 200 V VBO is too high for 2.5 V or 3.3 V PHY rails, and its 20 pF capacitance exceeds the <5 pF typical limit for 100 MHz differential signaling. It is optimized for 1–30 MHz telecom line pairs, not high-speed digital buses.
How does SMP100MC-200 differ from standard TRIAC-based protectors?
Unlike general-purpose TRIACs, SMP100MC-200 is process-optimized for fast, symmetric breakover (VBO tolerance ±5%), low dynamic impedance (<1 Ω during conduction), and guaranteed IH ≥150 mA across –40 °C to +150 °C. It also undergoes 100% surge screening per GR-1089 test waveforms, which standard TRIACs do not.
Is SMB (DO-214AA) footprint compatible with legacy DO-15 or DO-204AL packages?
No - SMB has a 5.1–5.6 mm body length and 3.3–3.95 mm width, while DO-15 measures 4.0–4.6 mm × 2.5–3.1 mm and DO-204AL (DO-41) is 5.2–5.7 mm × 2.5–2.9 mm. Pad layout, thermal pad area, and solder paste volume differ significantly; mechanical adaptation is required for retrofit.
