Product details

Overview

TB2300H-13-F from Diodes Incorporated is a bidirectional surface-mount thyristor surge protective device (TSPD) designed for telecom and data line overvoltage clamping. It features 190V stand-off voltage (VDRM), 265V breakover voltage (VBO), 100A peak pulse current (10/1000μs), 400A peak pulse current (8/20μs), and 80pF 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 TB2300H-13-F datasheet, TB2300H-13-F pinout, TB2300H-13-F application, or TB2300H-13-F equivalent, key selection criteria include stand-off voltage tolerance, bidirectional clamping symmetry, low off-state capacitance for high-speed lines, surge current rating under standardized waveforms, and SMB package thermal performance in compact telecom modules.

Technical Context

This TSPD operates as a voltage-triggered crowbar device: it remains in high-impedance off-state until applied voltage exceeds VBO (265V typ.), then latches into low-voltage on-state (VT ≤ 3.5V @ 1A) until current falls below IH (150–800mA). Its oxide-glass passivated junction ensures stable breakdown characteristics across -40°C to +150°C junction temperature.

Unlike TVS diodes, it provides inherent latching behavior with defined holding current (IH) and breakover current (IBO = 50–800mA), enabling self-sustaining clamping during sustained surges while maintaining high off-state impedance (<5μA at 190V) to avoid signal loading on protected lines.

Key Specifications

Parameter	Value and Actual Design Meaning
VDRM	190V - maximum continuous working voltage before conduction; sets operating margin for 176V AC telecom lines.
VBO	265V typ. - precise voltage threshold triggering clamping; ensures reliable response before equipment damage.
I_PP (10/1000μs)	100A - surge handling per GR-1089-CORE; supports multi-event durability in central office environments.
I_PP (8/20μs)	400A - higher-energy transient immunity per IEC 61000-4-5; critical for lightning-induced surges.
C_O	80pF @ 1MHz/2V - minimal signal distortion on broadband lines (e.g., ADSL2+, VDSL2).
IH	150–800mA - minimum current to sustain conduction; enables clean recovery after surge decay.
R_θJA	100°C/W - thermal resistance defining power derating in SMB footprint; limits average dissipation to ~0.5W at 70°C ambient.

Pinout & Package

Package: SMB (DO-214AA), surface-mount, bidirectional - no polarity marking required. Molded plastic case meets UL 94V-0; terminals feature matte tin plating, solderable per MIL-STD-202 Method 208.

Pin/Terminal	Circuit Role	Design Meaning
Anode/Cathode (symmetrical)	Surge current path terminal	Identical bidirectional terminals enable single-device protection of AC-coupled or differential lines without orientation constraints.
Case	Non-electrical mechanical reference	Plastic body provides electrical isolation; no internal connection - mounting pad serves only thermal/mechanical function.

Key Features

Feature	Design Value
Bidirectional clamping	Enables single-device protection of AC or differential signal pairs (e.g., RS-485, xDSL) without polarity concerns.
Oxide-glass passivated junction	Ensures stable VBO and low leakage (<5μA) over temperature and lifetime, critical for field-reliable telecom deployments.
High off-state impedance / low on-state voltage	Maintains signal integrity during normal operation (no loading), yet drops to ≤3.5V during surge to limit downstream stress.
UL Recognized Component (File E156346)	Validates safety compliance for end-equipment certification under UL497B, reducing time-to-market for telecom infrastructure.

Applications

DSL Line Protection

T1/E1 Interface Protection

Use Scenario: Protecting copper pair interfaces in DSLAMs and CPE against induced lightning surges and AC power cross events.

IC Role / Device Role: Bidirectional crowbar clamping device placed between tip/ring and ground, triggered by overvoltage exceeding 265V.

Use Value: 80pF capacitance avoids attenuation of ADSL2+ signals up to 30 MHz; 400A 8/20μs rating handles repeated surges per GR-1089-CORE.

Use Scenario: Safeguarding T1/E1 framer ICs and line drivers in telecom access equipment exposed to secondary lightning currents.

IC Role / Device Role: Primary surge shunt on balanced 100Ω transmission lines, operating symmetrically on both conductors.

Use Value: 190V VDRM aligns with ±130V peak T1 line swing; latching behavior sustains clamping through 10ms surges without follow-on current issues.

PoE Data Line Protection

Industrial Ethernet Port Protection

Use Scenario: Shielding Power over Ethernet (IEEE 802.3af/at) data pairs from surge coupling via shared cabling infrastructure.

IC Role / Device Role: Bidirectional TSPD installed across differential pairs (e.g., MDI-X), clamping mode-switching transients.

Use Value: Low 80pF capacitance preserves 100BASE-TX signal integrity; 100A 10/1000μs rating covers common-mode surges in building wiring.

Use Scenario: Hardening RJ-45 ports in industrial PLCs and HMIs against EFT and lightning surges in factory-floor environments.

IC Role / Device Role: Front-end surge suppressor on Ethernet PHY side, coordinated with downstream TVS for multi-stage protection.

Use Value: UL recognition simplifies IEC 61000-4-5 system-level testing; SMB footprint allows dense layout in space-constrained DIN-rail enclosures.

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
SMCJ220CA	Unidirectional TVS diode; 220V standoff, 400A 8/20μs, but no latching behavior - requires external current limiting.	Suitable for non-latching, fast-response clamping where follow-on current is managed externally.	Select when lower clamping voltage (≈240V) and faster response (<1ns) are prioritized over surge endurance.
TPSMB220A	Unidirectional TVS; 220V standoff, 400A 8/20μs, 150pF capacitance - higher parasitic capacitance than TB2300H-13-F.	Acceptable for DC-biased lines where capacitance impact is less critical (e.g., RS-232).	Choose only if bidirectionality is not required and board layout cannot accommodate symmetrical placement.

Compared with SMCJ220CA and TPSMB220A, TB2300H-13-F delivers true bidirectional latching clamping with lower capacitance (80pF vs. ≥150pF) and intrinsic hold-current control - essential for protecting AC-coupled telecom interfaces without external circuitry.

FAQ

What is the maximum continuous operating voltage for TB2300H-13-F?

The maximum repetitive off-state voltage (VDRM) is 190V. This defines the highest RMS or DC voltage the device can block continuously without triggering. Operation above this level risks unintended conduction; design margin should account for waveform peaks and temperature drift (ΔVBR/ΔTJ = 0.1%/°C).

Does TB2300H-13-F require a gate trigger or external circuit to activate?

No - TB2300H-13-F is a gateless, voltage-triggered thyristor. It conducts automatically when voltage across its terminals exceeds the breakover voltage (VBO = 265V typ.). No external bias, resistor, or control signal is needed, simplifying PCB layout and reducing BOM count.

How does TB2300H-13-F recover after a surge event?

After clamping, the device remains latched in low-impedance state until current falls below the holding current (IH = 150–800mA). In typical telecom line applications with series impedance, current decays naturally within <30ms. No reset circuitry is required - recovery is autonomous and repeatable.

Can TB2300H-13-F be used in DC circuits?

Yes - its bidirectional structure allows use in AC or DC applications, but in pure DC systems, ensure the load or source impedance guarantees current drops below IH after clamping. For DC power rails, verify that post-surge current decay meets the 30ms recovery window to prevent latch-up and thermal runaway.
