Product details
Overview
TB2600H-13 from Diodes Incorporated is a bidirectional surface-mount thyristor surge protective device (TSPD) designed for primary-level AC/DC line protection in telecom and industrial interfaces. It features a 220V stand-off voltage (VDRM), 300V breakover voltage (VBO), 100A peak pulse current (10/1000μs), 400A peak pulse current (8/20μs), and 80pF off-state capacitance - enabling robust transient suppression in DSL, POTS, and PoE-powered equipment.
For engineers reviewing the TB2600H-13 datasheet, TB2600H-13 pinout, TB2600H-13 application, or TB2600H-13 equivalent, key selection criteria include bidirectional clamping behavior, low leakage (<5μA at 220V), fast response to ITU-T K.21-compliant surges, and SMB package compatibility with high-density PCB layouts.
Technical Context
This TSPD operates as a voltage-triggered, self-resetting crowbar device that latches into low-impedance conduction upon exceeding its breakover voltage (300V typical), sustaining conduction until current falls below holding threshold (150–800mA). Its oxide-glass passivated junction ensures stable VBO over temperature (±0.1%/°C drift) and long-term reliability under repetitive surge stress.
Unlike TVS diodes, it delivers higher surge current handling (400A @ 8/20μs) with lower clamping voltage during sustained overcurrent events, making it suitable for applications where GR-1089-CORE and IEC 61000-4-5 Level 4 compliance is required without external current limiting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM | 220V - Maximum continuous AC/DC operating voltage before triggering; defines system working voltage margin. |
| VBO | 300V typical - Breakover voltage threshold at which device switches to low-impedance state; sets surge initiation level. |
| Ipp (10/1000μs) | 100A - Peak surge current capability for long-duration lightning-induced transients per GR-1089-CORE. |
| Ipp (8/20μs) | 400A - Surge rating for fast-rising, high-energy transients per IEC 61000-4-5. |
| CO | 80pF - Off-state capacitance at 2VDC bias and 1MHz; enables minimal signal distortion in broadband telecom lines. |
| IDRM | <5μA at 220V - Low leakage ensures negligible standby power loss and no false triggering in high-impedance circuits. |
| ITSM | 50A - Non-repetitive on-state surge current rating for half-cycle 60Hz faults; supports short-circuit withstand. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional - no polarity marking; terminals are symmetrical anode/cathode configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Current entry terminal in forward conduction mode | Identical to Cathode in bidirectional operation; interchangeable due to symmetric structure. |
| Cathode (K) | Current exit terminal in forward conduction mode | Functionally identical to Anode; device triggers regardless of voltage polarity across terminals. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional surge clamping | Enables single-device protection of AC lines or differential pairs without polarity constraints. |
| Oxide-glass passivated junction | Ensures stable VBO over temperature and humidity; eliminates parameter drift in harsh environments. |
| High off-state impedance & low on-state voltage | Leakage <5μA at rated VDRM and VT = 3.5V @ 1A enable minimal interference in standby and clean clamping during fault. |
| UL Recognized Component (File E156346) | Validates safety compliance for end-equipment certification including UL497B and FCC Part 68. |
Applications
| DSL Line Interface Protection | PoE Power Sourcing Equipment (PSE) |

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 |
|---|---|---|---|
| Littlefuse SXHV220 | Same VDRM (220V), but higher VBO (325V); 120pF capacitance vs. 80pF. | Higher clamping voltage may increase stress on downstream components; less suitable for high-frequency DSL lines. | Prefer when higher VBO margin is needed for aging or temperature derating, not for bandwidth-sensitive interfaces. |
| Littelfuse TISP4240H3BJR-S | Lower VDRM (130V); 500A 8/20μs rating; TO-220 package (not SMB). | Requires board redesign; unsuitable for space-constrained telecom modules. | Select only if higher surge rating outweighs PCB area penalty and system voltage permits 130V standoff. |
Compared with SXHV220 and TISP4240H3BJR-S, TB2600H-13 offers optimal balance of low capacitance, SMB footprint, and precise 220V/300V voltage coordination - critical for compact, high-speed telecom protection where layout area and signal fidelity are constrained.

FAQ
What is the maximum operating temperature for TB2600H-13?
The TB2600H-13 has a specified junction temperature range of –40°C to +150°C and a storage temperature range of –55°C to +150°C. Its thermal resistance from junction to lead is 20°C/W, enabling reliable operation at full-rated surge current in ambient temperatures up to +85°C when mounted on a PCB with adequate copper pour.
Does TB2600H-13 require a gate trigger or external control circuit?
No - TB2600H-13 is a three-layer, gateless thyristor structure that triggers autonomously when voltage across its terminals exceeds the breakover voltage (300V typical). It requires no external bias, timing circuit, or driver; conduction ceases automatically when load current drops below the holding current threshold (150–800mA).
How does TB2600H-13 differ from a standard TVS diode?
TB2600H-13 uses thyristor-based crowbar action rather than avalanche breakdown. It provides higher surge current capacity (400A vs. typical 100A for SMB TVS), lower clamping voltage under high-current surges, and inherent latching behavior - but requires sufficient load current decay to reset, unlike instantaneous recovery in TVS devices.
Is TB2600H-13 compliant with RoHS and halogen-free standards?
Yes - TB2600H-13 features a lead-free matte tin finish and green molding compound containing no halogens or antimony, fully compliant with EU Directive 2002/95/EC (RoHS) and JEDEC JS709A. The "-13" suffix denotes tape-and-reel packaging with RoHS-compliant plating and environmentally optimized materials.
