Product details

Overview

TB1100H-13 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 90V maximum repetitive off-state voltage (V_DRM), 130V breakover voltage (V_BO), 100A peak pulse current (10/1000μs), 400A peak pulse current (8/20μs), and 120pF 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 TB1100H-13 datasheet, TB1100H-13 pinout, TB1100H-13 application, or TB1100H-13 equivalent, key selection criteria include stand-off voltage margin vs. line operating voltage, clamping response time under fast-rising transients, off-state capacitance impact on high-frequency signal integrity, and thermal derating for sustained surge duty cycles in outdoor telecom cabinets.

Technical Context

This thyristor-based TSPD operates as a voltage-triggered crowbar device: it remains in high-impedance off-state until applied voltage exceeds V_BO (130V typ.), then latches into low-voltage on-state (<3.5V at 1A) with holding current ≥150mA. Its bidirectional symmetry eliminates polarity concerns in AC-coupled telecom lines.

Thermal design relies on R_θJL = 20°C/W (junction-to-lead) and R_θJA = 100°C/W (junction-to-ambient), requiring PCB copper pour for sustained 50A non-repetitive on-state current handling. The oxide-glass passivated junction ensures stable V_BO drift of +0.1%/°C over –40°C to +150°C junction range.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DRM	90V - Maximum continuous AC/DC line voltage the device blocks without triggering; sets minimum isolation margin for 75V nominal DSL lines.
V_BO	130V (typ.) - Voltage threshold at which device switches to low-impedance state; defines clamping onset point for surge events.
I_PP (10/1000μs)	100A - Peak surge current capability per GR-1089-CORE; determines survivability against lightning-induced longitudinal surges.
C_O	120pF - Off-state capacitance at 2V DC bias and 1MHz; directly impacts insertion loss and return loss above 1MHz in broadband data lines.
I_H	150–800mA - Minimum current required to maintain on-state; ensures reliable latch during multi-cycle surges while allowing recovery after transient decay.
R_θJL	20°C/W - Junction-to-lead thermal resistance; enables direct heat transfer to PCB copper via cathode/anode leads, critical for repeated surge dissipation.

Pinout & Package

Package: SMB (DO-214AA), surface-mount, bidirectional, no polarity marking. Molded plastic case rated UL 94V-0; weight ≈0.093g.

Pin/Terminal	Circuit Role	Design Meaning
Anode (A)	Current entry terminal in forward conduction mode	Connected to line side of protected circuit; forms symmetrical pair with Cathode for bidirectional surge shunting.
Cathode (K)	Current exit terminal in forward conduction mode	Connected to ground or reference plane; provides low-inductance path for surge current return during both polarities.

Key Features

Feature	Design Value
Bidirectional protection in single device	Eliminates need for back-to-back diode or dual-TSPD layouts; reduces BOM count and PCB area in differential line protection.
Oxide-glass passivated junction	Ensures long-term stability of V_BO and leakage (<5μA at 90V) across temperature and humidity stress, critical for field-deployed telecom gear.
High off-state impedance / low on-state voltage	Leakage <5μA at rated V_DRM minimizes standby power loss; on-state voltage ≤3.5V at 1A limits power dissipation during clamping.
UL Recognized Component (File E156346)	Validates construction, flammability (94V-0), and surge performance per UL497B - accelerates end-equipment safety certification.

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
Littelfuse SP1003-090	V_DRM = 90V, I_PP = 100A (10/1000μs), but C_O = 250pF - 108% higher than TB1100H-13.	Higher capacitance limits use to sub-1MHz applications; unsuitable for VDSL2 or G.fast line cards.	Select when cost sensitivity outweighs high-frequency signal integrity requirements.
Bourns TBU-CA120-200-WH	Not a thyristor: it's a resettable overcurrent protector (TBU); no V_BO, no clamping action - operates as series current limiter.	Provides overcurrent blocking only; requires downstream TVS for voltage clamping - adds component count and coordination complexity.	Choose only where coordinated overcurrent + overvoltage protection is architecturally separated.

Compared with SP1003-090 and TBU-CA120-200-WH, TB1100H-13 uniquely delivers low-capacitance bidirectional clamping with precise V_BO control - essential for broadband telecom interfaces where signal fidelity and surge response must coexist.

FAQ

What is the maximum continuous operating voltage for TB1100H-13?

The maximum repetitive off-state voltage (V_DRM) is 90V DC or RMS AC. This is the highest steady-state voltage the device reliably blocks without triggering. Operation above this level risks premature conduction or degradation. Derating is recommended for elevated ambient temperatures or high-humidity environments per the datasheet's IDRM vs. TJ curve.

Does TB1100H-13 require a trigger circuit or gate control?

No. TB1100H-13 is a gateless, voltage-triggered thyristor. It switches automatically when the applied voltage across its terminals exceeds the breakover voltage (V_BO ≈130V). No external bias, timing signal, or control logic is needed - making it inherently simple and reliable for passive surge protection.

How does TB1100H-13 behave after conducting a surge?

After triggering, TB1100H-13 latches in the low-voltage on-state until current falls below the holding current (I_H ≥150mA). Recovery to high-impedance off-state occurs within ≤30ms once line current decays - verified per Note 5 in the datasheet. This self-resetting behavior avoids manual reset or replacement after transient events.

Can TB1100H-13 be used in automotive applications?

No. TB1100H-13 is not qualified to AEC-Q101 or automotive temperature/humidity/EMC standards. Its design targets telecom and industrial data-line surge protection per GR-1089-CORE and IEC 61000-4-5. Automotive CAN/LIN bus protection requires components with specified automotive-grade transient immunity, extended temperature range (–40°C to +125°C), and qualification documentation.
