Diodes Incorporated TB2300M-13-F

Overview

TB2300M-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 190V maximum repetitive off-state voltage (VDRM), 50A peak pulse current (10/1000μs), 265V breakover voltage (VBO), 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 TB2300M-13-F datasheet, TB2300M-13-F pinout, TB2300M-13-F application, or TB2300M-13-F equivalent, key selection criteria include stand-off voltage margin vs. line operating voltage, bidirectional clamping symmetry, low capacitance for high-speed signal integrity, thermal resistance (RθJL = 20°C/W), and UL 156346 recognition for telecom safety certification.

Technical Context

This TSPD operates as a voltage-triggered, self-resetting crowbar device with oxide-glass passivated junction. Its bidirectional structure eliminates polarity concerns and supports AC-coupled lines without external diode bridging. The 0.1%/°C positive temperature coefficient of VBR ensures stable breakdown across -40°C to +150°C junction range.

Triggering occurs when applied voltage exceeds VBO (265V typ.), transitioning from high-impedance off-state to low-voltage on-state (VT ≤ 3.5V @ 1A). Recovery to off-state requires current decay below IH (150–800mA), with surge recovery time ≤30ms - critical for repeated lightning-induced transients in central office equipment.

FAQ

What is the maximum operating temperature for TB2300M-13-F?

The junction temperature range is -40°C to +150°C, with thermal resistance RθJL = 20°C/W enabling reliable operation at full 50A surge rating when mounted on ≥100mm² 2oz copper. Derating is not required up to 125°C ambient if PCB thermal design meets datasheet layout guidelines.

Does TB2300M-13-F require a series current-limiting resistor?

No - unlike MOVs or TVS diodes, this thyristor operates as a crowbar and relies on system impedance to limit on-state current. External resistors are unnecessary and would degrade clamping speed; proper PCB trace inductance and upstream fusing are the recommended coordination methods.

How does TB2300M-13-F compare to standard TVS diodes for telecom surge protection?

It offers higher surge current (50A vs. typical 30A for SMB TVS), lower clamping voltage under high-current transients (≤3.5V vs. >10V for 50A), and inherent bidirectionality without stacking. However, its ~265V VBO is less precise than TVS breakdown voltage, making it better suited for coarse overvoltage blocking than fine voltage regulation.

Is TB2300M-13-F compatible with lead-free reflow processes?

Yes - it uses matte tin-plated terminals and green halogen-free molding compound, qualified for JEDEC J-STD-020 Level 1 moisture sensitivity and compatible with standard SnAgCu reflow profiles peaking at 260°C, with no popcorn risk or solderability degradation.
