Product details

Overview

TB1800H-13-F from Diodes Incorporated is a bidirectional surface-mount thyristor surge protective device (TSPD) rated for 160V stand-off voltage, 100A peak pulse current (10/1000μs), and 400A peak pulse current (8/20μs), with 120pF off-state capacitance and 3.5V on-state voltage at 1A. It provides robust overvoltage clamping in telecom line interfaces, DSL/Cable modem protection circuits, and industrial Ethernet ports.

For engineers reviewing the TB1800H-13-F datasheet, TB1800H-13-F pinout, TB1800H-13-F application, or TB1800H-13-F equivalent, key selection criteria include stand-off voltage margin relative to operating line voltage, peak pulse current rating for system-level surge immunity (IEC 61000-4-5 Level 4), off-state capacitance impact on high-speed signal integrity, and thermal resistance (20°C/W junction-to-lead) for sustained surge duty cycles.

Technical Context

This TSPD operates as a voltage-triggered crowbar device: it remains in high-impedance off-state until applied voltage exceeds its 220V breakover threshold (V_BO), then latches into low-voltage conduction (<3.5V at 1A) until current falls below 150–800mA holding current (I_H). Its oxide-glass passivated junction ensures stable V_BO drift of only +0.1%/°C over temperature.

The device is inherently bidirectional with no polarity marking, enabling symmetric AC line protection without external diode bridging. Its SMB package supports automated SMT assembly and delivers 100°C/W junction-to-ambient thermal resistance under standard PCB layout conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
Stand-off Voltage (V_DRM)	160V - Maximum continuous AC/DC line voltage the device blocks before triggering
Breakover Voltage (V_BO)	220V - Threshold at which device switches from blocking to conducting state
Peak Pulse Current (10/1000μs)	100A - Surge handling capability per GR-1089-CORE and IEC 61000-4-5 waveform
On-State Voltage (V_T)	3.5V @ 1A - Low clamping voltage during conduction, minimizing power dissipation during surge
Off-State Capacitance (C_O)	120pF @ 2V DC bias, 1MHz - Minimal signal distortion in broadband telecom/data lines
Holding Current (I_H)	150–800mA - Minimum current required to maintain conduction after triggering
Thermal Resistance (R_θJL)	20°C/W - Enables efficient heat transfer to PCB copper pour or heatsink tab

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 SP1003-010	100V V_DRM, 200A I_PP (8/20μs), 150pF C_O, SMB package	Lower stand-off voltage limits use to sub-100V AC lines; higher capacitance affects >10MHz signals	Select when higher surge current rating is prioritized over high-frequency signal fidelity
Vishay V130LA20AP	130V V_DRM, 100A I_PP (10/1000μs), 100pF C_O, DO-15 axial lead	Through-hole mounting only; lower capacitance suits legacy telecom designs but lacks SMT scalability	Select for cost-sensitive, non-high-speed legacy systems where manual assembly is acceptable

Compared with SP1003-010 and V130LA20AP, TB1800H-13-F offers optimal balance of 160V stand-off margin, 120pF capacitance for broadband line interfaces, and SMB SMT compatibility-making it preferred for next-generation DSL, DOCSIS 3.1, and industrial Ethernet designs requiring automated assembly and signal integrity.

FAQ

What is the maximum continuous operating voltage for TB1800H-13-F?

The maximum rated repetitive off-state voltage (V_DRM) is 160V. This is the highest RMS or DC voltage the device can block continuously without triggering. Operation above this level risks unintended conduction and potential failure. Derating by 20% is recommended for long-term reliability in high-temperature environments.

How does TB1800H-13-F differ from unidirectional TVS diodes in surge protection?

TB1800H-13-F is a thyristor-based crowbar device with latching behavior: once triggered, it stays on until current drops below its 150–800mA holding threshold. Unidirectional TVS diodes clamp non-latching and reset immediately after surge decay. This makes TB1800H-13-F superior for high-energy surges where sustained clamping is needed, but requires careful circuit design to ensure current interruption.

Is TB1800H-13-F compatible with lead-free reflow profiles?

Yes. TB1800H-13-F features matte tin-plated terminals and is qualified for lead-free reflow soldering per JEDEC J-STD-020. Its moisture sensitivity level is MSL 1, meaning it can be stored indefinitely at ≤30°C/60% RH without baking prior to assembly. Peak reflow temperature must not exceed 260°C for ≤10 seconds.

Does TB1800H-13-F require external gate control or biasing?

No. TB1800H-13-F is a passive, voltage-triggered device with no gate terminal or control pins. It operates solely based on applied voltage across its terminals exceeding the 220V breakover threshold (V_BO). No external bias, timing circuitry, or driver is required-enabling simple, two-terminal integration into line protection networks.
