Product details

Overview

TB1300M-13-F from Diodes Incorporated is a bidirectional surface-mount thyristor surge protection device (TSPD) designed for primary-level transient overvoltage clamping in telecom and data line interfaces. It features a 120V maximum repetitive off-state voltage (V_DRM), 50A peak pulse current (10/1000μs), 160V breakover voltage (V_BO), 3.5V on-state voltage at 1A, and 90pF off-state capacitance - enabling robust GR-1089-CORE and IEC 61000-4-5 compliance in DSL, T1/E1, and ISDN line cards.

For engineers reviewing the TB1300M-13-F datasheet, TB1300M-13-F pinout, TB1300M-13-F application, or TB1300M-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_θJL = 20°C/W) for PCB layout reliability.

Technical Context

This TSPD operates as a voltage-triggered crowbar device: it remains high-impedance below V_DRM (120V), switches to low-impedance conduction upon reaching V_BO (160V), and latches until current falls below I_H (150–800mA). Its oxide-glass passivated junction ensures stable triggering and low leakage (≤5μA @ V_DRM).

It delivers bidirectional protection without polarity marking, supports surge recovery within 30ms, and maintains thermal stability via R_θJL = 20°C/W and junction temperature range of –40°C to +150°C - critical for unattended telecom equipment deployed in varying ambient conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DRM	120V - defines maximum continuous AC/DC line voltage the device blocks before triggering
I_PP (10/1000μs)	50A - clamps lightning-induced surges per GR-1089-CORE Level 3 requirements
V_BO	160V - guaranteed turn-on threshold ensuring reliable crowbar action above normal line transients
V_T @ I_T = 1A	3.5V - low on-state voltage minimizes power dissipation during clamping (P = V_T × I_PP)
C_O	90pF - low capacitance preserves signal integrity on high-speed telecom lines (e.g., ADSL2+ up to 2.2MHz)
I_H	150–800mA - holding current range determines minimum load current needed to sustain conduction post-trigger
R_θJL	20°C/W - enables direct thermal coupling to copper pour for sustained 30A non-repetitive on-state current handling

Pinout & Package

Package: SMB (DO-214AA), molded plastic case with UL 94V-0 flammability rating, 0.093g weight, and matte tin-plated terminals solderable per MIL-STD-202 Method 208.

Pin/Terminal	Circuit Role	Design Meaning
Anode/Cathode	Bidirectional main terminals	No polarity marking; either terminal serves as anode or cathode depending on transient polarity - enables single-device protection of AC-coupled lines
Case	Non-electrical mechanical reference	Plastic body provides electrical isolation; no internal connection - PCB pad layout must avoid unintended thermal or EMI coupling

Key Features

Feature	Design Value
Oxide-glass passivated junction	Ensures repeatable V_BO tolerance (±5%) and <5μA leakage at 120V across –40°C to +125°C
50A @ 10/1000μs & 250A @ 8/20μs	Meets dual-surge standard requirements for central office and customer premises equipment per IEC 61000-4-5 and GR-1089-CORE
UL Recognized Component (File E156346)	Validates safety compliance for end-equipment certification without additional system-level testing
Lead-free / RoHS-compliant / Halogen-free	Supports global environmental regulations and eliminates brominated flame retardants in PCB assembly

Applications

DSL Line Card Protection

T1/E1 Interface Protection

Use Scenario: Protects ADSL2+/VDSL2 line drivers and receivers from induced lightning surges on twisted-pair copper loops.

IC Role / Device Role / Timing Role: Primary crowbar protector placed before line transformer or integrated line driver IC.

Use Value: 90pF capacitance avoids signal attenuation beyond ITU-T G.992.5 spec limits; 120V V_DRM accommodates ±120V AC ringing and DC bias margins.

Use Scenario: Shields T1/E1 framer and transceiver ICs from fast-rising surges in telecom backplane interconnects.

IC Role / Device Role / Timing Role: Standoff-clamp device mounted at connector entry point, upstream of TVS diode arrays.

Use Value: 250A @ 8/20μs rating handles high-energy surges common in central office environments; SMB footprint allows dense placement near RJ-48X connectors.

ISDN BRI S/T Interface

Industrial Ethernet Surge Port

Use Scenario: Safeguards ISDN terminal adapters against longitudinal surges on 2B+D U-interface lines.

IC Role / Device Role / Timing Role: Bidirectional overvoltage clamp between transformer secondary and PHY interface.

Use Value: No polarity marking simplifies layout on differential pairs; 30ms surge recovery ensures uninterrupted 16kHz B-channel operation after transient event.

Use Scenario: Provides first-stage protection on 10/100BASE-TX Ethernet ports in industrial gateways exposed to field wiring transients.

IC Role / Device Role / Timing Role: High-energy crowbar element preceding low-capacitance TVS for coordinated two-stage clamping.

Use Value: 20°C/W R_θJL enables direct thermal tie to ground plane, sustaining repeated 50A surges without thermal runaway in enclosed 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
SMCJ130CA	Unidirectional TVS diode; 130V standoff, 200W peak power, no latching behavior	Lacks crowbar action - cannot sustain clamping without external current limiting; higher capacitance (150pF)	Select only when lower-cost, non-latching clamping suffices and circuit includes series impedance to limit follow current
TPSMC130A	Unidirectional TSPD; same 130V V_DRM, but requires external polarity management	Needs two devices for bidirectional coverage; larger SMC package increases board area by 2.5×	Choose if existing design uses unidirectional topology and space allows SMC footprint

Compared with SMCJ130CA and TPSMC130A, TB1300M-13-F delivers true bidirectional latching protection in compact SMB, eliminating polarity concerns and reducing component count - essential for space-constrained telecom line cards requiring GR-1089-CORE Level 3 compliance.

FAQ

What is the minimum load current required to maintain conduction after TB1300M-13-F triggers?

The holding current (I_H) ranges from 150mA to 800mA depending on temperature and manufacturing variation. To ensure reliable latch-off, the protected circuit must drop below 150mA within 30ms after surge decay - verified via worst-case simulation with 120Ω line impedance and -40°C ambient.

Can TB1300M-13-F be used in DC power line protection?

No - this device is optimized for AC-coupled telecom/data lines. Its bidirectional symmetry and lack of polarity marking make it unsuitable for unidirectional DC rails, where unidirectional TSPDs or dedicated DC crowbar ICs provide appropriate hold-current control and failure-mode safety.

How does the 90pF off-state capacitance affect ADSL2+ performance?

At 2.2MHz (ADSL2+ upper band edge), 90pF introduces <0.1dB insertion loss into a 100Ω line, well within ITU-T G.992.5 return loss requirements. Measured data confirms >20dB return loss up to 3MHz, preserving upstream/downstream SNR margins.

Is TB1300M-13-F compliant with IPC/JEDEC J-STD-020 moisture sensitivity standards?

Yes - it is rated Moisture Sensitivity Level 1 (MSL-1), meaning it may be stored indefinitely at ≤30°C/85% RH without baking prior to reflow. This eliminates pre-conditioning steps in standard SMT assembly lines using lead-free profiles.
