Product details

Overview

TB2600L-13-F from Diodes Incorporated is a bidirectional surface-mount thyristor surge protective device (TSPD) designed for telecom and industrial line protection. It features a 220 V maximum repetitive off-state voltage (V_DRM), 30 A peak pulse current (10/1000 µs), 300 V breakover voltage (V_BO), 3.5 V on-state voltage at 1 A, and 40 pF off-state capacitance - enabling robust transient suppression in DSL, POTS, and Ethernet interfaces.

For engineers reviewing the TB2600L-13-F datasheet, TB2600L-13-F pinout, TB2600L-13-F application, or TB2600L-13-F equivalent, key selection criteria include stand-off voltage margin vs. line operating voltage, hold-current stability over temperature, surge waveform compliance (IEC 61000-4-5, ITU-T K.21), SMB package thermal resistance (R_θJL = 30 °C/W), and bidirectional clamping symmetry.

Technical Context

This TSPD operates as a voltage-triggered crowbar device: it remains high-impedance below 220 V, triggers at ~300 V (V_BO), latches into low-impedance conduction upon reaching 50–800 mA breakover current (I_BO), and sustains conduction until current falls below 150–800 mA holding current (I_H). Its oxide-glass passivated junction ensures stable triggering across -40 to +150 °C.

Unlike TVS diodes, it provides bidirectional clamping without polarity marking and exhibits positive temperature coefficient for breakdown voltage (+0.1 %/°C), improving coordination with upstream fuses under sustained overvoltage. Off-state capacitance remains stable at 40 pF up to 2 V reverse bias, minimizing signal distortion in broadband telecom lines.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DRM	220 V - Maximum continuous AC/DC line voltage the device blocks without triggering
I_PP (10/1000 µs)	30 A - Peak surge current capability per GR-1089-CORE; defines minimum line fuse rating
V_BO	300 V - Voltage threshold at which device switches from blocking to conducting state
V_T @ I_T = 1 A	3.5 V - On-state voltage drop during clamping; determines power dissipation (P = V_T × I_PP)
C_O	40 pF - Low junction capacitance minimizes insertion loss in 1–30 MHz DSL/Ethernet signals
R_θJL	30 °C/W - Junction-to-lead thermal resistance enables reliable heat transfer to PCB copper in SMB footprint
I_H range	150–800 mA - Holding current window defines minimum load current required to maintain latch-on state

Pinout & Package

Package: SMB (DO-214AA), surface-mount, bidirectional - no polarity marking; terminals are symmetrical anode/cathode connections.

Pin/Terminal	Circuit Role	Design Meaning
Anode (A)	Current entry terminal during positive half-cycle conduction	Electrically identical to Cathode; interchangeable due to bidirectional symmetry
Cathode (K)	Current entry terminal during negative half-cycle conduction	Same physical terminal as Anode; no functional distinction in layout or routing

Key Features

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	200 V V_DRM, 20 A I_PP (10/1000 µs), 270 V V_BO, SMB package	Lower stand-off voltage limits use to ≤170 V AC lines; reduced surge margin for GR-1089-CORE	Select when lower clamping voltage is prioritized over higher line voltage tolerance
Bourns TISP4240M3JR-S	240 V V_DRM, 30 A I_PP, 320 V V_BO, SOT-23 package (higher R_θJA)	SOT-23 thermal limitation restricts duty cycle in repeated surge environments	Select for space-constrained designs where 240 V margin suffices and PCB area is critical

Compared with SP1003-020 and TISP4240M3JR-S, TB2600L-13-F offers the highest V_DRM/V_BO ratio (220/300 V) among SMB-packaged TSPDs, enabling superior coordination with 230 VAC-powered telecom equipment while maintaining industry-standard thermal performance.

FAQ

What is the minimum load current required to prevent false turn-off after triggering?

The holding current (I_H) ranges from 150 to 800 mA. To ensure reliable latch-on behavior, the protected circuit must sustain ≥800 mA through the device post-triggering - typically ensured by line impedance or external current sources. Below this, the device may prematurely reset, leaving the line unprotected during residual surge tail.

How does temperature affect breakover voltage stability?

Breakover voltage exhibits a +0.1 %/°C positive temperature coefficient. At 125 °C junction temperature, V_BO increases by ~10% versus 25 °C (i.e., ~330 V), improving coordination with upstream fuses but requiring verification against system overvoltage margins at elevated ambient temperatures.

Can TB2600L-13-F be used in DC power line protection?

Yes - its 220 V V_DRM supports DC bus voltages up to 220 V. However, DC applications require careful hold-current design: the load must draw ≥800 mA continuously to sustain conduction after surge initiation, otherwise the device resets and re-exposes the downstream circuit to overvoltage.

Is the SMB package lead-free and RoHS-compliant?

Yes - TB2600L-13-F features matte tin-plated terminals, conforms to EU Directive 2002/95/EC (RoHS), and uses halogen-free, antimony-free green molding compound. Moisture sensitivity level is rated at Level 1 per J-STD-020, allowing unlimited floor life before reflow.
