Product details

Overview

TB1100M-13-F from Diodes Incorporated is a bidirectional surface-mount thyristor surge protection device (TSPD) designed for primary-level transient overvoltage clamping in telecom and data line interfaces. It features a 90 V maximum repetitive off-state voltage (V_DRM), 50 A peak pulse current (10/1000 µs), 130 V breakover voltage (V_BO), 3.5 V on-state voltage at 1 A, and 90 pF off-state capacitance - enabling robust GR-1089-CORE and IEC 61000-4-5 compliance in DSL, T1/E1, and PoE-powered edge equipment.

For engineers reviewing the TB1100M-13-F datasheet, TB1100M-13-F pinout, TB1100M-13-F application, or TB1100M-13-F equivalent, key selection criteria include stand-off voltage margin relative to line operating voltage, hold-current stability across temperature, surge waveform compatibility (8/20 µs vs. 10/1000 µs), and SMB package thermal resistance (R_θJA = 100 °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, then latches into low-voltage conduction mode with <3.5 V drop at 1 A. Its bidirectional symmetry enables protection of AC-coupled lines without polarity concerns.

Thermal design relies on junction-to-lead resistance of 20 °C/W and junction temperature limits from –40 °C to +150 °C; holding current (150–800 mA) ensures reliable reset after surge decay, while 0.1 %/°C positive temperature coefficient of V_BO supports stable triggering across industrial temperature ranges.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DRM	90 V - Maximum continuous AC/DC line voltage the device blocks before triggering
I_PP (10/1000 µs)	50 A - Peak surge current capability matching GR-1089-CORE Level 3 telecom requirements
V_BO	130 V - Voltage threshold at which device switches from blocking to conducting state
V_T @ I_T = 1 A	3.5 V - Low clamping voltage during conduction, minimizing stress on downstream circuitry
C_O	90 pF - Low off-state capacitance preserving signal integrity on high-speed data lines (e.g., xDSL)
I_H	150–800 mA - Holding current range ensuring reliable return to off-state after surge clearance
R_θJA	100 °C/W - Thermal resistance defining maximum power dissipation under still-air conditions

Pinout & Package

Package: SMB (DO-214AA), surface-mount, bidirectional, non-polarized case with matte tin-plated terminals and UL 94V-0 molded plastic body (6.8 mm × 4.3 mm × 2.3 mm).

Pin/Terminal	Circuit Role	Design Meaning
Anode/Cathode (A/K)	Interchangeable main terminals	Bidirectional symmetry means either terminal serves as anode or cathode depending on transient polarity - no marking or orientation requirement
Case	Non-electrical mechanical interface	Plastic body provides insulation and mechanical anchoring; no thermal or electrical connection to die

Key Features

Feature	Design Value
Oxide-glass passivated junction	Enables stable V_BO and low leakage (<5 µA at 90 V) over lifetime and temperature
UL Recognized Component (File E156346)	Validates safety compliance for end-equipment certification without additional system-level testing
Lead-free / RoHS-compliant construction	Meets EU Directive 2002/95/EC with matte tin finish and halogen-free molding compound
High off-state impedance & low on-state voltage	Minimizes standby power loss and clamping overshoot during surge events

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
SM1100A-S	Same V_DRM (90 V) and V_BO (130 V), but lower I_PP = 30 A (10/1000 µs); SMB package, RoHS compliant	Not rated for GR-1089-CORE Level 3; suitable only for lighter-duty industrial data lines	Select when cost sensitivity outweighs telecom-grade surge margin and system-level testing confirms 30 A sufficiency
P6SMB110A	Unidirectional TVS diode (not thyristor); same V_BR ≈ 110 V, but clamps rather than latches; higher C_O = 150 pF	Lacks hold-current behavior - resets immediately post-surge; unsuitable for sustained overvoltage scenarios	Choose only for fast-reset, low-energy transients where crowbar action is unnecessary and capacitance tolerance permits

Compared with SM1100A-S and P6SMB110A, TB1100M-13-F delivers verified 50 A surge handling with latching behavior and lower capacitance - critical for telecom line integrity and compliance with multi-standard surge tests requiring sustained current conduction.

FAQ

What is the minimum breakover current (I_BO) required to trigger TB1100M-13-F?

The datasheet specifies I_BO between 50 mA and 800 mA at 25 °C. Triggering occurs reliably above 50 mA, but actual value depends on junction temperature and rate of voltage rise (dV/dt). For design margin, use 800 mA as worst-case minimum required to ensure consistent turn-on under elevated temperature or slow-rising transients.

Can TB1100M-13-F be used in AC mains input protection?

No - TB1100M-13-F is rated for signal/data line protection only, with V_DRM = 90 V and thermal limits unsuitable for 120/230 VAC RMS applications. Its R_θJA = 100 °C/W and I_TSM = 30 A (8.3 ms) do not support sustained AC fault currents. Use dedicated AC-rated MOVs or GDTs instead.

How does junction temperature affect holding current (I_H)?

Figure 5 shows normalized holding current increases with temperature: at 125 °C, I_H is ~1.5× the 25 °C value. Since I_H ranges from 150–800 mA at 25 °C, it may reach up to ~1.2 A at max operating temperature - requiring careful verification that load current falls below this threshold to guarantee proper reset after surge clearance.

Is TB1100M-13-F compatible with lead-free reflow soldering profiles?

Yes - it is qualified for lead-free reflow per J-STD-020, with Moisture Sensitivity Level 1 (unlimited floor life at ≤30 °C/60% RH) and matte tin-plated terminals rated for peak temperatures up to 260 °C. Standard IPC/JEDEC J-STD-020D profile with 60–90 sec above 217 °C is fully supported.
