Product details

Overview

TB1300H-13-F from Diodes Incorporated is a bidirectional surface-mount thyristor surge protective device (TSPD) designed for primary-level AC/DC line protection in telecom and industrial interfaces. It features a 120V stand-off voltage (VDRM), 160V breakover voltage (VBO), 100A peak pulse current (10/1000μs), 400A peak pulse current (8/20μs), and 120pF off-state capacitance - enabling robust transient suppression in DSL, POTS, and PoE-powered equipment.

For engineers reviewing the TB1300H-13-F datasheet, TB1300H-13-F pinout, TB1300H-13-F application, or TB1300H-13-F equivalent, key selection criteria include stand-off voltage matching, bidirectional clamping symmetry, low off-state capacitance for high-frequency signal integrity, and UL 497B/IEC 61000-4-5 compliance for telecom surge immunity certification.

Technical Context

This TSPD operates as a voltage-triggered, self-resetting crowbar device with symmetrical bidirectional conduction. Its oxide-glass passivated junction ensures stable VBO over temperature (±0.1%/°C drift), while high off-state impedance (>100 MΩ at 120V) minimizes standby leakage in always-on lines.

It latches on during overvoltage events above VBO and remains conducting until current falls below the holding current (IH = 150–800 mA), with full recovery within 30 ms. The device is inherently polarity-agnostic and requires no external trigger circuitry or biasing.

Key Specifications

Parameter	Value and Actual Design Meaning
VDRM	120 V - Maximum continuous AC/DC working voltage before conduction begins; sets minimum system operating margin.
VBO	160 V - Breakover threshold where device transitions to low-impedance state; defines clamping onset point.
I_PP (10/1000μs)	100 A - Peak surge current handling per GR-1089-CORE; determines survivability against lightning-induced surges.
I_PP (8/20μs)	400 A - Higher-energy surge rating per IEC 61000-4-5; supports Type 2/3 SPD coordination.
C_O	120 pF - Off-state capacitance at 2V DC bias and 1 MHz; enables use on <10 Mbps data lines without signal distortion.
I_H	150–800 mA - Minimum current required to sustain conduction; ensures reliable reset after surge decay.
R_θJA	100 °C/W - Junction-to-ambient thermal resistance; informs derating in SMB package under natural convection.

Pinout & Package

Package: SMB (DO-214AA), surface-mount, bidirectional, non-polarized device with two terminals. Case material is UL 94V-0 molded plastic; terminals are matte tin-plated for lead-free soldering.

Pin/Terminal	Circuit Role	Design Meaning
Anode/Cathode (symmetrical)	Surge current path	Identical bidirectional terminals - either terminal may serve as anode or cathode depending on transient polarity; no marking or orientation dependency.
Case	Thermal and mechanical interface	Molded plastic body provides electrical isolation and thermal path to PCB copper; no internal connection to case.

Key Features

Feature	Design Value
Bidirectional surge clamping	Enables single-device protection of AC-coupled or differential telecom lines (e.g., tip/ring) without polarity concerns.
Oxide-glass passivated junction	Ensures long-term VBO stability and low parameter drift across -40°C to +150°C junction temperature range.
UL 497B recognition	Validates suitability for primary protection in telephone network interface units (NIUs) and DSLAM line cards per safety standard.
Green molding compound	Halogen- and antimony-free encapsulation meets IPC-4101D and JEDEC J-STD-020 moisture sensitivity Level 1 requirements.

Applications

DSL Line Interface Protection

POTS Telephone Line Protection

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

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

Use Value: Clamps transients above 160V while maintaining <120pF loading - preserving signal integrity up to 30 MHz.

Use Scenario: Shields analog subscriber line interface circuits (SLICs) in PBX and VoIP gateways from induced surges.

IC Role / Device Role / Timing Role: Standby-mode protector across tip/ring pair; triggers only during overvoltage events >160V.

Use Value: Zero standby current draw (<5 µA at 120V) avoids loading SLIC bias networks or affecting loop supervision.

PoE Power Sourcing Equipment (PSE)

Industrial RS-485 Data Lines

Use Scenario: Safeguards 48V DC power pairs in IEEE 802.3af/at PSE controllers against EFT and surge coupling.

IC Role / Device Role / Timing Role: DC-side surge limiter on power feed lines; coordinates with secondary TVS on data pairs.

Use Value: Withstands 400A (8/20μs) surges while limiting let-through voltage to <25V during clamping - protecting downstream DC-DC converters.

Use Scenario: Protects RS-485 transceivers in factory automation systems exposed to motor-switching noise and ground potential differences.

IC Role / Device Role / Timing Role: Bidirectional shunt protector across A/B differential bus lines; placed adjacent to connector.

Use Value: Symmetrical clamping ensures equal protection for both polarities of common-mode surges, critical for half-duplex bus reliability.

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 SP1003-01WTG	130V VDRM, 170V VBO, 100A I_PP (10/1000μs), SMB package, but higher C_O = 200pF	Less suitable for >10 Mbps data lines due to higher capacitance; better for voice-only POTS	Select when lower cost or broader distributor stock outweighs capacitance sensitivity.
Bourns TISP4240H3BJR-S	135V VDRM, 180V VBO, 100A I_PP, SOT-23 package (smaller footprint, higher R_θJA)	Lower surge energy handling due to thermal limits; limited to secondary-side or low-duty-cycle protection	Choose for space-constrained designs where peak surge exposure is infrequent and lower than 100A.

Compared with SP1003-01WTG and TISP4240H3BJR-S, TB1300H-13-F offers optimal balance of 120pF capacitance, 120V stand-off, and SMB thermal capability - making it preferred for primary-line telecom protection where signal bandwidth and thermal robustness are jointly critical.

FAQ

What is the maximum continuous operating voltage for TB1300H-13-F?

The maximum repetitive off-state voltage (VDRM) is 120 V DC or RMS AC. This is the highest steady-state voltage the device blocks without triggering. Operation above this level risks unintended conduction, especially at elevated temperatures where VBO drifts downward by 0.1% per °C.

Does TB1300H-13-F require a series current-limiting resistor?

No - unlike MOVs or GDTs, this thyristor-based TSPD does not require external current limiting to sustain conduction. However, system-level current must fall below the holding current (150–800 mA) for automatic reset; insufficient load current may cause latch-up until power cycle.

Can TB1300H-13-F be used in DC applications like PoE power feeds?

Yes - its bidirectional structure functions identically on DC lines. In 48V PoE PSE applications, it clamps positive or negative surges relative to the DC rail, provided the steady-state voltage remains ≤120V and the load can sink ≥150 mA during clamping to ensure reset.

Is TB1300H-13-F compatible with lead-free reflow processes?

Yes - it features matte tin-plated terminals rated for Pb-free soldering per MIL-STD-202, Method 208, and complies with J-STD-020 moisture sensitivity Level 1, allowing standard reflow profiles without pre-baking.
