Diodes Incorporated TB2600M-13-F

Overview

TB2600M-13-F from Diodes Incorporated is a bidirectional surface-mount thyristor surge protection device (TSPD) designed for telecom and data line transient suppression. It features a 220V maximum repetitive off-state voltage (V_DRM), 50A peak pulse current (10/1000μs), 300V breakover voltage (V_BO), 3.5V on-state voltage at 1A, and 60pF off-state capacitance - enabling robust GR-1089-CORE and IEC 61000-4-5 compliance in DSL, T1/E1, and PoE interface protection.

For engineers reviewing the TB2600M-13-F datasheet, TB2600M-13-F pinout, TB2600M-13-F application, or TB2600M-13-F equivalent, key selection criteria include stand-off voltage margin vs. line operating voltage, hold-current stability across temperature, surge waveform derating (e.g., 250A @ 8/20μs), and SMB package thermal resistance (R_θJA = 100°C/W) for PCB layout validation.

Technical Context

This TSPD operates as a voltage-triggered crowbar device: it remains high-impedance below 220V, triggers at ~300V (V_BO), latches into low-voltage conduction (≤3.5V @ 1A), and holds until current falls below 150–800mA (I_H). Its oxide-glass passivated junction ensures stable breakdown over temperature (ΔV_BR/ΔT_j = 0.1%/°C).

Designed for bidirectional AC/DC line protection, it requires no polarity marking and sustains 30A non-repetitive on-state current (I_TSM) for 8.3ms half-cycle surges. Off-state leakage stays ≤5μA at V_DRM, and junction capacitance remains 60pF at 2V bias - critical for maintaining signal integrity in broadband telecom interfaces.

FAQ

What is the recommended PCB layout for TB2600M-13-F to ensure optimal thermal performance?

Use minimum 25 mm² (5mm × 5mm) 2-oz copper pads per terminal, connected via ≥0.5mm wide traces to internal ground/power planes. Avoid thermal reliefs on pads; place device near edge of board with ≥2mm clearance to adjacent components. The SMB package relies on leadframe conduction - insufficient copper area causes junction temperatures to exceed 150°C during 50A surges.

Does TB2600M-13-F require external gate control or biasing?

No. TB2600M-13-F is a passive, voltage-triggered thyristor with no gate terminal. It operates autonomously: blocking below 220V, triggering at ~300V, and latching until load current drops below its holding current (150–800mA). No external circuitry, resistors, or capacitors are needed for basic surge suppression.

How does TB2600M-13-F behave after a surge event - does it self-reset?

Yes, it self-resets once line current falls below its holding current (I_H). Recovery occurs within ≤30ms after current interruption. However, if the protected circuit maintains current >150mA post-surge (e.g., powered line), the device remains latched and must be power-cycled or current-interrupted externally to restore high-impedance state.

Can TB2600M-13-F be used in parallel for higher surge current handling?

No - parallel operation is not recommended. Manufacturing tolerances in V_BO (±5%) cause uneven current sharing; one device triggers first and absorbs most of the surge, risking thermal runaway. For >50A capability, select a higher-rated part (e.g., TB3100M-13-F) or implement staged protection with upstream current limiters.
