Product details
Overview
TB1100L-13-F from Diodes Incorporated is a bidirectional surface-mount thyristor surge protective device (TSPD) designed for primary-level transient overvoltage suppression in telecom and data line interfaces. It features a 90 V maximum repetitive off-state voltage (VDRM), 30 A peak pulse current (10/1000 µs), 130 V breakover voltage (VBO), 3.5 V on-state voltage at 1 A, and 60 pF off-state capacitance - enabling robust GR-1089-CORE and IEC 61000-4-5 compliance in DSL, T1/E1, and ISDN line cards.
For engineers reviewing the TB1100L-13-F datasheet, TB1100L-13-F pinout, TB1100L-13-F application, or TB1100L-13-F equivalent, key selection criteria include stand-off voltage margin vs. line operating voltage, peak pulse current rating under 10/1000 µs waveform, off-state capacitance impact on high-frequency signal integrity, and thermal resistance (RθJL = 30 °C/W) for PCB layout derating.
Technical Context
This TSPD operates as a voltage-triggered crowbar device: it remains in high-impedance off-state until applied voltage exceeds its 130 V breakover threshold (VBO), then latches into low-voltage conduction (<3.5 V at 1 A) until current falls below 150–800 mA holding current (IH). Its oxide-glass passivated junction ensures stable triggering across –40 to +150 °C junction temperature.
Designed for bidirectional protection without polarity marking, it delivers symmetrical clamping for AC-coupled lines. The 0.1 %/°C positive temperature coefficient of VBO supports predictable voltage margin shift with thermal drift, while 60 pF off-state capacitance minimizes insertion loss in ≤10 MHz telecom signals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM | 90 V - Maximum continuous AC/DC line voltage the device blocks before triggering; sets minimum isolation margin for 75 V nominal telecom lines. |
| IPP (10/1000 µs) | 30 A - Peak surge current handling per GR-1089-CORE; defines single-event energy absorption capability (≈1.2 J). |
| VBO | 130 V - Voltage at which device switches to low-impedance state; provides defined clamping onset above VDRM. |
| VT @ IT = 1 A | 3.5 V - On-state voltage drop during conduction; determines power dissipation (3.5 W) and thermal stress during surge. |
| CO | 60 pF - Off-state junction capacitance at 2 V DC bias and 1 MHz; limits high-frequency insertion loss in broadband data lines. |
| RθJL | 30 °C/W - Thermal resistance from junction to lead; enables direct PCB copper pour thermal management without heatsink. |
| IH range | 150–800 mA - Minimum current required to maintain conduction; ensures reliable reset after surge decay in series-impedance-limited circuits. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional, non-polarized case with matte tin-plated terminals. UL 94V-0 molded plastic body, 0.093 g weight, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (A/K) | Interchangeable bidirectional terminals | No polarity marking; either terminal serves as anode or cathode depending on instantaneous voltage polarity - enables single-device AC protection. |
| Case | Non-electrical mechanical interface | Insulated plastic housing; no internal connection to leads - allows mounting on grounded or floating PCB planes without shorting. |
Key Features
| Feature | Design Value |
|---|---|
| Oxide-glass passivated junction | Ensures stable VBO and leakage performance over temperature and lifetime, critical for field-reliability in unattended telecom equipment. |
| Bidirectional operation in single package | Eliminates need for back-to-back diac or dual-TSPD layout, reducing BOM count and PCB area by ≥40% in AC line protection. |
| 30 A 10/1000 µs surge rating | Meets GR-1089-CORE Level 3 requirements for central office equipment, supporting multi-year deployment without degradation. |
| 60 pF off-state capacitance | Preserves signal integrity up to 10 MHz in T1/E1 (1.544/2.048 Mbps) and basic ISDN applications without equalization. |
| UL Recognized Component (File E156346) | Validates safety compliance for end-equipment certification, reducing time-to-market for FCC Part 68 and UL 497B listed products. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional thyristor surge protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SM15T10A (STMicroelectronics) | Unidirectional, 10 V VDRM, 15 kW peak power, 100 pF CO | Requires back-to-back configuration for AC lines; higher capacitance limits use to <2 MHz signals. | Select only for DC-biased or low-frequency AC paths where polarity is controlled and bandwidth is not critical. |
| P6SMB110A (ON Semiconductor) | Unidirectional TVS diode, 110 V VBR, 600 W peak power, 150 pF CO, no latching behavior | Lacks hold-on capability; clamps but does not crowbar - may fail under sustained overvoltage. | Prefer for short-duration ESD or fast transients; avoid in GR-1089-CORE Level 3 telecom surge scenarios requiring latch-and-hold. |
Compared with SM15T10A and P6SMB110A, TB1100L-13-F offers true bidirectional latching protection with lower capacitance and higher surge current endurance - making it uniquely suitable for telecom line cards where AC symmetry, long surge duration, and signal fidelity are mandatory.

FAQ
What is the maximum continuous operating voltage for TB1100L-13-F?
The maximum repetitive off-state voltage (VDRM) is 90 V DC or RMS AC. This is the highest steady-state voltage the device reliably blocks without triggering. Operation above this value risks unintended conduction; design margin should maintain at least 20% below VDRM for reliability under temperature and aging effects.
Does TB1100L-13-F require a gate trigger signal?
No. TB1100L-13-F is a three-layer bidirectional thyristor (DIAC-like structure) with no gate terminal. It triggers automatically when voltage across its terminals exceeds the 130 V breakover threshold (VBO) - no external control or biasing is needed.
How does TB1100L-13-F reset after conducting a surge?
It resets automatically when current through the device falls below its holding current range (150–800 mA). In typical telecom line applications with series impedance (e.g., 100 Ω transformer winding), surge current decays within milliseconds, allowing return to high-impedance off-state without external intervention.
Can TB1100L-13-F be used in automotive applications?
No. TB1100L-13-F is not qualified to AEC-Q101 or automotive environmental standards. Its design targets telecom and industrial data line surge protection per GR-1089-CORE and IEC 61000-4-5 - not automotive load-dump or ISO 7637-2 waveforms. Use only in applications aligned with its specified standards and temperature range (–40 to +150 °C junction).
