Product details
Overview
TB1100L-13 from Diodes Incorporated is a bi-directional surface-mount thyristor surge protective device (TSPD) with 90 V stand-off voltage, 30 A peak pulse current (10/1000 µs), and 150 A peak pulse current (8/20 µs), designed for telecom line protection in DSL, T1/E1, and xDSL interfaces where bidirectional transient suppression is required.
For engineers reviewing the TB1100L-13 datasheet, TB1100L-13 pinout, TB1100L-13 application, or TB1100L-13 equivalent, key selection criteria include off-state capacitance (60 pF), breakover voltage (130 V), holding current range (150–800 mA), thermal resistance (30 °C/W junction-to-lead), and SMB package compatibility with automated SMT assembly.
Technical Context
This TSPD operates as a voltage-triggered crowbar device: it remains high-impedance below 90 V (VDRM), triggers at 130 V (VBO) with ≥50 mA breakover current, and latches low-impedance conduction until current falls below 150–800 mA (IH). Its oxide-glass passivated junction ensures stable triggering over -40 to +150 °C.
It delivers bidirectional clamping without polarity marking, supports 10/1000 µs and 8/20 µs surge waveforms per GR-1089-CORE and IEC 61000-4-5, and exhibits a positive temperature coefficient of breakdown voltage (+0.1 %/°C), enabling predictable derating across operating temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VDRM) | 90 V - Maximum continuous working voltage before conduction begins |
| Breakover Voltage (VBO) | 130 V - Trigger threshold under DC or slow-rising transients |
| Peak Pulse Current (10/1000 µs) | 30 A - Surge handling capability for long-duration telecom surges |
| Peak Pulse Current (8/20 µs) | 150 A - Robustness against fast, high-energy lightning-induced transients |
| Off-State Capacitance | 60 pF - Minimal signal distortion on high-speed data lines (e.g., ADSL2+) |
| Holding Current Range | 150–800 mA - Ensures reliable latch-off after surge when load current drops below threshold |
| Junction-to-Lead Thermal Resistance | 30 °C/W - Enables effective heat dissipation through PCB copper during repetitive surges |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bi-directional, polarity-free case with solderable matte tin-plated terminals per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (A/K) | Bi-directional main terminals | No polarity distinction; either terminal serves as anode or cathode depending on transient polarity |
| Case | Non-electrical mechanical body | Insulated plastic housing (UL 94V-0) with no internal connection or thermal sink requirement |
Key Features
| Feature | Design Value |
|---|---|
| Oxide-glass passivated junction | Ensures stable, repeatable breakover voltage with minimal drift over temperature and lifetime |
| Bi-directional protection in single device | Eliminates need for back-to-back diac or dual-TSPD layout, saving board space and BOM count |
| Low on-state voltage (3.5 V @ 1 A) | Minimizes power dissipation and thermal stress during clamping events |
| High off-state impedance (>100 MΩ typical) | Prevents signal leakage and insertion loss in protected data paths |
| Moisture sensitivity Level 1 | Enables standard SMT reflow without dry-pack or baking requirements |
Applications
| DSL Line Protection | T1/E1 Interface Protection |
|---|---|
Use Scenario: Protecting twisted-pair copper lines in ADSL/VDSL modems and central office line cards from induced lightning surges and AC power cross. IC Role / Device Role / Timing Role: Crowbar-type transient suppressor that latches during overvoltage and resets only when line current falls below holding threshold. Use Value: 60 pF capacitance preserves >26 MHz signal bandwidth; 90 V stand-off avoids false triggering on 75 V ring signals. | Use Scenario: Safeguarding T1/E1 framer ICs and transformer-coupled line drivers in telecom access equipment against longitudinal surges per GR-1089-CORE. IC Role / Device Role / Timing Role: Bidirectional voltage-triggered switch that clamps both polarities of differential surges without polarity biasing. Use Value: 150 A (8/20 µs) rating meets IEC 61000-4-5 Level 4 immunity; SMB footprint aligns with industry-standard telecom layout spacing. |
| xDSL Customer Premises Equipment | Industrial Ethernet Port Protection |
Use Scenario: Integrated surge protection in residential gateways and VoIP adapters connecting to POTS lines carrying broadband data. IC Role / Device Role / Timing Role: Standby-mode protector that remains non-conductive until transient exceeds 130 V, then conducts to shunt energy to ground. Use Value: 30 °C/W RθJL allows direct thermal coupling to PCB copper pour, sustaining repeated 30 A surges without thermal runaway. | Use Scenario: Protecting RS-485/RS-422 PHYs in industrial controllers exposed to EFT and surge in factory environments. IC Role / Device Role / Timing Role: High-impedance standby element that transitions to low-impedance state within nanoseconds upon overvoltage detection. Use Value: 150–800 mA holding current range accommodates variable load currents in powered bus systems while ensuring clean recovery post-surge. |
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 array; 90 V standoff, 100 A (8/20 µs), but no latching behavior | Lacks crowbar action - clamps then recovers instantly; unsuitable for sustained overcurrent scenarios | Select only if transient duration is <1 µs and system lacks current-limiting impedance |
| P6SMB90CA | Same unidirectional TVS topology; higher 100 A (8/20 µs) rating but 10× higher capacitance (600 pF) | Excessive capacitance degrades signal integrity on >1 MHz data lines | Acceptable only for low-speed analog or power-line applications, not DSL/xDSL |
Compared with SMBJ90CA and P6SMB90CA, TB1100L-13 provides true latching crowbar action, lower capacitance (60 pF vs. ≥600 pF), and superior thermal robustness (30 °C/W vs. >50 °C/W), making it uniquely suited for telecom line protection where sustained surge energy and signal fidelity are critical.

FAQ
What is the maximum allowable surge waveform duration for reliable operation?
TB1100L-13 is rated for 30 A peak pulse current at 10/1000 µs and 150 A at 8/20 µs per IEC 61000-4-5. It is not rated for longer durations such as 10/1000 ms. Exceeding specified waveform time constants risks thermal failure due to insufficient energy dissipation time.
Does TB1100L-13 require external gate control or biasing?
No. TB1100L-13 is a passive, voltage-triggered thyristor with no gate terminal. It operates autonomously based on applied voltage across its terminals and requires no external circuitry, bias resistors, or control signals to function.
How does junction temperature affect breakover voltage?
Breakover voltage increases linearly with junction temperature at +0.1 %/°C. At 125 °C, VBO rises to approximately 139 V (130 V × 1.09), ensuring safe margin above 90 V stand-off even under worst-case thermal conditions.
Can TB1100L-13 be used in AC mains protection?
No. TB1100L-13 is rated for telecom line-level voltages only (90 V stand-off). Its 130 V breakover voltage and lack of UL/IEC 61643-31 certification make it unsuitable for 120/230 VAC mains applications, where higher voltage ratings and safety agency approvals are mandatory.
