Product details
Overview
TB1100M-13 from Diodes Incorporated is a bi-directional surface-mount thyristor surge protective device (TSPD) designed for primary-level overvoltage protection in telecom and data line interfaces. It features 90 V stand-off voltage (VDRM), 130 V breakover voltage (VBO), 50 A peak pulse current (10/1000 µs), 250 A peak impulse current (8/20 µs), and 90 pF off-state capacitance - enabling robust GR-1089-CORE and IEC 61000-4-5 compliance in DSL, T1/E1, and PoE-powered equipment.
For engineers reviewing the TB1100M-13 datasheet, TB1100M-13 pinout, TB1100M-13 application, or TB1100M-13 equivalent, this device serves as a voltage-triggered crowbar protector with precise breakover threshold, low clamping voltage during conduction, and stable thermal performance up to +150°C junction temperature - critical for reliable surge immunity in space-constrained telecom front-ends.
Technical Context
This TSPD operates as a voltage-triggered silicon bilateral switch that latches into low-impedance conduction upon exceeding its 130 V breakover voltage (VBO), sustaining current until load current falls below 150–800 mA holding current (IH). Its oxide-glass passivated junction ensures stable leakage (<5 µA at 90 V) and repeatable triggering across -40°C to +150°C.
The device exhibits a positive temperature coefficient of breakdown voltage (+0.1%/°C), enabling predictable voltage margin shift with junction heating, and maintains <3.5 V on-state voltage (VT) at 1 A - minimizing power dissipation during surge events while supporting fast recovery (<30 ms) to high-impedance state post-surge.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM | 90 V - Maximum continuous reverse/forward blocking voltage before conduction; defines operating voltage window for protected lines. |
| VBO | 130 V - Breakover voltage threshold at which device triggers into low-impedance state; sets precise surge initiation point. |
| Ipp (10/1000 µs) | 50 A - Peak surge current handling per GR-1089-CORE; supports multi-event surge endurance in telecom infrastructure. |
| Ipp (8/20 µs) | 250 A - Higher-energy surge capability per IEC 61000-4-5; enables protection against lightning-induced transients. |
| CO | 90 pF - Off-state capacitance at 1 MHz / 2 V bias; minimizes signal distortion on high-speed data lines (e.g., ADSL2+). |
| IH | 150–800 mA - Holding current range; ensures reliable latch-off after surge when load current drops below threshold. |
| RJL | 20 °C/W - Junction-to-lead thermal resistance; supports direct PCB copper pour heatsinking for sustained surge duty cycles. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bi-directional, polarity-free device with two terminals. Molded plastic case meets UL 94V-0 flammability rating; moisture sensitivity level 1 per J-STD-020A.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (A/K) | Bi-directional main terminals | No polarity distinction; either terminal functions as anode or cathode depending on applied voltage polarity - enables single-device protection of AC or differential lines. |
| Case | Non-electrical mechanical interface | Plastic body provides electrical isolation; no internal connection to package - allows flexible PCB layout without grounding constraints. |
Key Features
| Feature | Design Value |
|---|---|
| Oxide-glass passivated junction | Ensures long-term stability of VBO and IDRM across temperature and humidity stress, critical for field-reliability in outdoor telecom cabinets. |
| Bi-directional surge response | Protects both polarities of AC-coupled or differential signals (e.g., RS-485, xDSL) without external diode bridges or dual-device layouts. |
| Low 90 pF off-state capacitance | Preserves signal integrity on broadband lines up to ~20 MHz; avoids attenuation or reflection in ADSL/VDSL physical layer interfaces. |
| UL Recognized Component (File E156346) | Validates safety compliance for end-equipment certification under UL497B, reducing time-to-market for telecom and industrial network gear. |
Applications
| DSL Line Interface Protection | T1/E1 Primary Protection |
|---|---|
Use Scenario: Protecting ADSL2+/VDSL2 line cards from lightning-induced surges on twisted-pair copper loops. IC Role / Device Role / Timing Role: Voltage-triggered crowbar device placed at line entry point to shunt surge energy before reaching transceiver ICs. Use Value: 90 pF capacitance prevents high-frequency signal loss; 130 V VBO aligns with ITU-T K.21 recommended protection levels for metallic telecommunication lines. | Use Scenario: Primary surge suppression in channelized T1/E1 multiplexers deployed in central office or remote terminal cabinets. IC Role / Device Role / Timing Role: Standby-mode protector that remains non-conductive until surge exceeds 130 V, then clamps line voltage to <3.5 V during conduction. Use Value: 250 A (8/20 µs) rating meets GR-1089-CORE Level 3 requirements; SMB footprint enables dense placement near RJ-48 connectors. |
| PoE Power Sourcing Equipment (PSE) | Industrial Ethernet Port Protection |
Use Scenario: Overvoltage safeguard on 48 V DC power pairs of IEEE 802.3af/at PSE controllers before magnetics and DC-DC conversion. IC Role / Device Role / Timing Role: Bidirectional clamp limiting transient excursions above ±130 V on power delivery lines during hot-plug or fault conditions. Use Value: 90 V VDRM provides 2× margin over 48 V nominal; low VT reduces power dissipation during sustained overcurrent events. | Use Scenario: Front-end protection of 10/100/1000BASE-T ports in programmable logic controllers (PLCs) and HMI panels exposed to factory floor ESD/lightning coupling. IC Role / Device Role / Timing Role: First-stage protector absorbing bulk surge energy before TVS diodes or integrated PHY ESD structures. Use Value: UL recognition simplifies industrial safety certification; SMB package supports automated reflow assembly alongside Ethernet magnetics. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional thyristor surge protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ90CA | Unidirectional TVS diode; 90 V standoff, 135 V clamping (at 100 A), no latching behavior. | Lacks crowbar action; requires series impedance for current limiting; higher clamping voltage degrades protection margin. | Choose only if fast response without hold-on behavior is required and system design includes current-limiting resistors. |
| TPSMF90CA | Bi-directional TVS diode; 90 V standoff, 144 V clamping (at 100 A); no latching, no holding current requirement. | Clamps but does not latch; lower surge current rating (100 A vs. 250 A 8/20 µs); faster reset but less energy absorption. | Select when rapid recovery is prioritized over high-energy surge handling, e.g., in low-power sensor nodes. |
Compared with SMBJ90CA and TPSMF90CA, TB1100M-13 delivers superior energy handling via latched conduction and lower clamping voltage during surge, making it preferred for infrastructure-grade telecom and industrial Ethernet where sustained overvoltage must be actively shorted.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The TB1100M-13 supports continuous operation from -40°C to +150°C junction temperature. Its 20 °C/W junction-to-lead thermal resistance allows effective heat transfer to PCB copper, and derating curves in the datasheet confirm full-rated surge performance up to +125°C ambient with adequate copper area.
Does TB1100M-13 require an external gate trigger circuit?
No. TB1100M-13 is a three-layer, gateless thyristor structure that triggers solely based on applied voltage exceeding its 130 V breakover threshold (VBO). It requires no external control signal, biasing, or gate drive - functioning autonomously as a voltage-activated crowbar.
How does the device recover after a surge event?
After triggering, TB1100M-13 remains latched in low-impedance conduction until load current falls below its 150–800 mA holding current (IH). Recovery time to high-impedance state is ≤30 ms. No external reset is needed - recovery occurs naturally when system current decays post-surge.
Can TB1100M-13 be used in DC power line protection?
Yes - its bi-directional nature and 90 V VDRM make it suitable for protecting ±48 V DC PoE power pairs. However, ensure the steady-state load current remains above the minimum holding current (150 mA) during normal operation to prevent unintended dropout; verify with actual line current profiles.
