Product details

Overview

TB2600H-13-F 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 (V_DRM), 300V breakover voltage (V_BO), 100A peak pulse current (10/1000μs), 400A surge rating (8/20μs), and 80pF off-state capacitance - enabling robust GR-1089-CORE and IEC 61000-4-5 compliance in DSL, POTS, and PoE-powered equipment.

For engineers reviewing the TB2600H-13-F datasheet, TB2600H-13-F pinout, TB2600H-13-F application, or TB2600H-13-F equivalent, key selection criteria include bidirectional clamping behavior, low leakage (<5μA at 220V), fast surge response (<100ns turn-on), thermal resistance (R_θJA = 100°C/W), and SMB package compatibility with automated SMT assembly for telecom line card designs.

Technical Context

This TSPD operates as a voltage-triggered, self-resetting crowbar device - latching into low-impedance conduction upon exceeding V_BO (300V typical), sustaining conduction until current falls below holding threshold (I_H = 150–800mA), then recovering to high-impedance state within ≤30ms. Its oxide-glass passivated junction ensures stable breakdown characteristics across -40°C to +150°C.

Unlike TVS diodes, it delivers higher surge current handling (400A @ 8/20μs) with minimal capacitance (80pF), making it suitable for protecting high-bandwidth analog lines where capacitive loading must be constrained - such as xDSL line drivers, ISDN BRI interfaces, and Ethernet PHY front-ends.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DRM	220V - Maximum continuous reverse/forward blocking voltage before triggering; sets operating margin above 170VAC RMS line peaks.
V_BO	300V typical - Breakover voltage threshold; defines precise clamping initiation point for transient overvoltage events.
I_PP (10/1000μs)	100A - Surge current capability per GR-1089-CORE; supports multi-event endurance in central office environments.
C_O	80pF @ 1MHz, 2V bias - Low parasitic capacitance preserves signal integrity on broadband telecom lines up to 30MHz.
I_H	150–800mA - Holding current range; determines minimum load current required to sustain conduction and avoid false re-triggering.
R_θJA	100°C/W - Junction-to-ambient thermal resistance; informs derating requirements in enclosed or high-ambient industrial enclosures.

Pinout & Package

Package: SMB (DO-214AA), surface-mount, bidirectional - no polarity marking; molded plastic case rated UL 94V-0, 0.093g weight, moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning
Anode/Cathode (symmetrical)	Surge current path	Identical terminals; bidirectional conduction enables single-device protection of AC lines without orientation constraints.
Case (exposed pad)	Thermal path / mechanical anchor	Not electrically connected; provides thermal dissipation and board adhesion but requires non-conductive PCB layout clearance.

Key Features

Feature	Design Value
Bidirectional clamping	Enables single-component protection of AC-coupled telecom lines (e.g., POTS, xDSL) without external bridge or dual-device layout.
Oxide-glass passivated junction	Ensures stable V_BO drift <0.1%/°C and long-term reliability under repeated surge stress in humid industrial environments.
UL Recognized (File E156346)	Validates compliance for end-equipment safety certification in North American telecom infrastructure deployments.
Lead-free & halogen-free	Meets RoHS Directive 2002/95/EC and JEDEC J-STD-020 moisture sensitivity Level 1 - supports lead-free reflow and green manufacturing.

Applications

DSL Line Interface Protection

PoE Power Sourcing Equipment (PSE)

Use Scenario: Protecting ADSL/VDSL line drivers from lightning-induced surges on twisted-pair copper loops.

IC Role / Device Role / Timing Role: Primary crowbar-type surge protector placed between line transformer secondary and codec IC input.

Use Value: 80pF capacitance avoids signal degradation at >2MHz frequencies; 300V V_BO allows safe operation above 170VAC line peaks while clamping transients to <40V.

Use Scenario: Safeguarding IEEE 802.3af/at PSE controller ICs and MOSFETs against cable discharge events during hot-plug insertion.

IC Role / Device Role / Timing Role: Bidirectional overvoltage clamp on the 48V DC power pair, upstream of DC-DC converter input.

Use Value: 100A 10/1000μs rating handles worst-case longitudinal surges; SMB footprint fits tight spacing near RJ45 magnetics.

ISDN BRI U-interface

Industrial RS-485 Node Protection

Use Scenario: Securing two-wire U-interface transceivers in European ISDN terminal adapters exposed to outdoor line transients.

IC Role / Device Role / Timing Role: Standoff-mode protector placed directly across tip/ring lines before line transformer primary.

Use Value: 220V V_DRM accommodates 150V RMS nominal line voltage with 50% safety margin; bidirectional symmetry eliminates polarity concerns.

Use Scenario: Hardening RS-485 transceivers in factory automation nodes connected via long unshielded cables in electrically noisy environments.

IC Role / Device Role / Timing Role: Secondary-level surge suppressor on differential bus lines (A/B), downstream of gas discharge tube primary protection.

Use Value: Fast turn-on (<100ns) limits voltage overshoot to <60V; low leakage (<5μA) prevents false triggering during normal 12V common-mode swings.

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 SP1003-020	200V V_DRM, 250V V_BO, 100A I_PP, SMB package, higher C_O (120pF)	Lower stand-off voltage limits use in 230VAC systems; higher capacitance may affect >10MHz signal paths.	Select when lower clamping voltage is prioritized over bandwidth preservation.
Bourns TISP4240H3BJR-S	240V V_DRM, 325V V_BO, 100A I_PP, SOT-23 package, 100pF C_O	SOT-23 footprint reduces board area but increases thermal resistance (R_θJA ≈ 150°C/W); less robust for repeated surges.	Prefer for space-constrained consumer-grade designs where single-event surge immunity suffices.

Compared with SP1003-020 and TISP4240H3BJR-S, TB2600H-13-F offers optimal balance of 220V stand-off margin, 80pF low capacitance, and SMB thermal performance - making it preferred for telecom line cards requiring multi-event endurance and broadband signal fidelity.

FAQ

What is the maximum continuous operating voltage for TB2600H-13-F?

The maximum repetitive off-state voltage (V_DRM) is 220V - meaning it reliably blocks voltages up to this level in both directions under steady-state conditions. This rating applies at T_A = 25°C; derating is required above 75°C ambient per the R_θJA = 100°C/W specification and thermal design margin.

How does TB2600H-13-F differ from a standard TVS diode?

TB2600H-13-F is a thyristor-based surge protector that latches into low-impedance conduction after triggering and remains on until current drops below its holding threshold (150–800mA). In contrast, TVS diodes clamp transiently without latching. This gives the TSPD higher surge current capacity (400A @ 8/20μs) and lower clamping voltage under sustained overcurrent, but requires sufficient load current to reset.

Is TB2600H-13-F compatible with lead-free reflow soldering?

Yes - TB2600H-13-F has a matte tin finish and is rated for lead-free reflow per MIL-STD-202, Method 208. Its moisture sensitivity level is J-STD-020 Level 1, meaning it can be stored indefinitely at ≤30°C/60% RH without baking prior to assembly. The SMB package withstands peak reflow temperatures up to 260°C.

Can TB2600H-13-F be used in AC mains input protection?

No - TB2600H-13-F is not rated for direct connection to AC mains (e.g., 120/230VAC inputs). Its 220V V_DRM provides insufficient margin for 230VAC RMS systems (peak ~325V), and it lacks certifications for mains isolation or fire-safety standards like UL 1449. It is intended for secondary-side telecom/data line protection only.
