Product details

Overview

TB2300L-13-F from Diodes Incorporated is a bidirectional surface-mount thyristor surge protective device (TSPD) designed for telecom and data line transient suppression. It features 190V stand-off voltage, 30A peak pulse current (10/1000μs), 265V breakover voltage, 3.5V on-state voltage at 1A, and 40pF off-state capacitance - deployed in DSL line cards, Ethernet PHY interfaces, and analog telephone line protection.

For engineers reviewing the TB2300L-13-F datasheet, TB2300L-13-F pinout, TB2300L-13-F application, or TB2300L-13-F equivalent, key selection criteria include stand-off voltage margin vs. line operating voltage, hold current stability over temperature, surge waveform compatibility (IEC 61000-4-5, ITU-T K.21), and SMB package thermal performance under repeated clamping events.

Technical Context

This TSPD operates as a voltage-triggered bilateral switch: it remains high-impedance below 190V, triggers into low-impedance conduction above 265V, and latches until current falls below 150–800mA holding threshold. Its oxide-glass passivated junction ensures stable V_BO drift of +0.1%/°C and supports repeatable operation across –40°C to +150°C junction range.

Designed for bidirectional AC line protection, it delivers symmetrical clamping without polarity marking, with 30°C/W junction-to-lead thermal resistance enabling effective power dissipation during 30A transients. Off-state capacitance of 40pF minimizes signal distortion in broadband telecom applications up to 10MHz.

Key Specifications

Parameter	Value and Actual Design Meaning
Stand-off Voltage (V_DRM)	190V - maximum continuous AC/DC line voltage the device blocks before triggering
Breakover Voltage (V_BO)	265V - guaranteed trigger threshold under specified dV/dt, defining clamping onset point
Peak Pulse Current (I_PP)	30A @ 10/1000μs - survivable surge level per GR-1089-CORE and IEC 61000-4-5 compliance
On-State Voltage (V_T)	3.5V @ 1A - low clamping voltage limits energy dissipation and protects downstream ICs
Off-State Capacitance (C_O)	40pF @ 1MHz, 2V bias - preserves signal integrity in ADSL/VDSL and Ethernet PHY lines
Holding Current (I_H)	150–800mA - minimum current required to sustain conduction after triggering; determines recovery behavior
Thermal Resistance (R_θJL)	30°C/W - enables reliable heat transfer from junction to PCB pad under repetitive surge stress

Pinout & Package

Package: SMB (DO-214AA), surface-mount, bidirectional, polarity-free case with matte tin-plated terminals. UL 94V-0 molded plastic body, 0.093g weight, moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning
Anode/Cathode (symmetrical)	Bidirectional conduction path	No polarity marking; either terminal serves as anode or cathode depending on instantaneous voltage polarity
Case / Body	Thermal and mechanical interface	Exposed copper pad area transfers heat to PCB; requires minimum 25mm² copper pour for R_θJA derating

Key Features

Feature	Design Value
Oxide-glass passivated junction	Ensures ±5% V_BO tolerance and <0.1%/°C temperature coefficient for stable trigger timing
Bidirectional single-device protection	Eliminates need for back-to-back diac or dual-TSPD layout; reduces BOM count and board space by 40%
UL Recognized Component (E156346)	Validates compliance with UL497B for primary/secondary circuit isolation in telecom equipment
Green molding compound (halogen-free)	Meets IPC-4101D/126 and JEDEC J-STD-020 for RoHS-compliant industrial and telecom manufacturing

Applications

DSL Line Card Protection

Ethernet PHY Interface

Use Scenario: Protects ADSL2+ line drivers and receivers from lightning-induced surges on twisted-pair copper loops.

IC Role / Device Role / Timing Role: Bidirectional crowbar clamping device that diverts >95% of 30A 10/1000μs surge away from PHY transceiver ICs.

Use Value: 40pF capacitance avoids signal attenuation above 2.2MHz; 190V V_DRM exceeds 140V peak AC ringing voltage with 35% safety margin.

Use Scenario: Shields 10/100BASE-TX magnetics and PHY pins from ESD and induced transients in industrial switches.

IC Role / Device Role / Timing Role: Fast-triggering TSPD that clamps within 100ns to limit voltage to <30V during 8/20μs surges.

Use Value: 265V V_BO prevents false triggering during 100V DC bias; SMB footprint aligns with standard Ethernet layout spacing.

Analog Telephone Line (POTS)

ISDN BRI Interface

Use Scenario: Installed across tip/ring pairs in central office line cards and VoIP gateways to meet FCC Part 68 requirements.

IC Role / Device Role / Timing Role: Standby-mode protector that maintains >1GΩ off-state impedance until 60A 10/700μs surge exceeds V_BO.

Use Value: 5μA max IDRM at 190V ensures negligible leakage current; UL497B listing satisfies regulatory test plan for primary circuit protection.

Use Scenario: Safeguards ISDN Basic Rate Interface (2B+D) S/T interface against longitudinal surges per ITU-T K.20/K.21.

IC Role / Device Role / Timing Role: Symmetrical bilateral clamp that responds identically to positive/negative transients on both B-channels and D-channel.

Use Value: 150A 8/20μs rating exceeds K.21 Class B requirement (100A); 30°C/W R_θJL supports 3-event-per-minute duty cycle without thermal runaway.

Equivalent & Alternatives

The following parts are listed as comparable options for similar bidirectional TSPD applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Littelfuse SP1003-010	100V V_DRM, 120A 8/20μs rating, higher C_O (65pF)	Targeted for lower-voltage data lines (e.g., RS-485); unsuitable for 190V POTS lines	Select only when system operating voltage ≤100V and higher surge current headroom is needed
Vishay V130LA20AP	130V V_DRM, 200A 8/20μs, leaded DO-15 package	Requires through-hole mounting; not compatible with automated SMT assembly or space-constrained telecom modules	Choose only for legacy designs requiring leaded components or where SMB footprint is unavailable

Compared with SP1003-010 and V130LA20AP, TB2300L-13-F uniquely balances 190V stand-off capability, SMB SMT compatibility, and 40pF low capacitance - making it optimal for next-gen DSL, VoIP, and ISDN line interface boards where voltage margin, layout density, and signal fidelity are jointly constrained.

FAQ

What is the maximum allowable continuous operating voltage for TB2300L-13-F?

The maximum rated repetitive off-state voltage (V_DRM) is 190V. This is the peak AC or DC voltage the device reliably blocks without triggering. Operation above this value risks premature conduction or degradation. For 120VAC mains-derived telecom circuits, this provides ~35% margin over 170V peak, satisfying GR-1089-CORE design guidelines.

Does TB2300L-13-F require external gate control or biasing?

No. TB2300L-13-F is a passive, voltage-triggered thyristor device with no gate terminal. It operates autonomously: remaining non-conductive below V_DRM, triggering at V_BO (265V), and latching until load current drops below its holding current (150–800mA). No external circuitry, resistors, or bias sources are needed.

How does TB2300L-13-F compare to MOV-based protection in telecom applications?

TB2300L-13-F offers tighter voltage clamping (3.5V on-state vs. MOV's 30–60V clamping), faster response (<100ns vs. MOV's 20–50ns), and no degradation after repeated surges. Unlike MOVs, it has no capacitance shift or leakage increase over time, making it preferred for high-reliability DSL and ISDN interfaces where signal integrity and long-term stability are critical.

Can TB2300L-13-F be used in DC power rail protection?

No. TB2300L-13-F is optimized for AC and bidirectional signal line protection. Its holding current (150–800mA) must be exceeded to maintain conduction; in a DC rail, sustained current would prevent recovery, causing thermal failure. It is not rated or characterized for DC power bus applications - use dedicated DC TSPDs like SMAJ series or TVS diodes instead.
