Product details

Overview

TB1500H-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 140V maximum repetitive off-state voltage (V_DRM), 100A peak pulse current (10/1000μs), 180V breakover voltage (V_BO), 3.5V on-state voltage at 1A, and 120pF off-state capacitance - enabling robust transient suppression in DSL, POTS, and PoE-powered equipment.

For engineers reviewing the TB1500H-13-F datasheet, TB1500H-13-F pinout, TB1500H-13-F application, or TB1500H-13-F equivalent, key selection criteria include stand-off voltage margin vs. system operating voltage, 100A I_PP capability under GR-1089-CORE waveforms, bidirectional clamping symmetry, thermal resistance (R_θJL = 20°C/W), and UL 156346 recognition for safety-critical telecom deployments.

Technical Context

This TSPD operates as a voltage-triggered, self-resetting crowbar device with positive temperature coefficient for breakdown voltage (ΔV_BR/ΔT_J = 0.1%/°C), ensuring stable triggering across –40°C to +150°C junction temperatures. Its oxide-glass passivated junction enables high off-state impedance (>100MΩ at 140V) and low leakage (<5μA).

Triggering occurs when applied voltage exceeds V_BO (180V typ.), initiating conduction with <3.5V on-state drop at 1A and sustaining conduction until current falls below holding current (I_H = 150–800mA). Recovery time is ≤30ms, supporting repeated surge events per GR-1089-CORE and IEC 61000-4-5 compliance requirements.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DRM	140V - Maximum continuous AC/DC line voltage the device blocks without triggering; sets minimum system operating margin for 120VAC or 48VDC telecom lines.
I_PP (10/1000μs)	100A - Peak surge current handling per GR-1089-CORE; defines clamping energy capacity for lightning-induced transients on subscriber loops.
V_BO	180V (typ.) - Breakover voltage threshold; determines precise clamping onset point above V_DRM, critical for protecting downstream TVS or ICs.
V_T @ I_T = 1A	3.5V - Low on-state voltage minimizes power dissipation during conduction, reducing thermal stress during sustained surges.
C_O	120pF @ 1MHz, 2VDC - Low junction capacitance avoids signal integrity degradation in high-speed data lines (e.g., ADSL2+, VDSL2).
R_θJL	20°C/W - Junction-to-lead thermal resistance enables direct PCB copper pour heatsinking; supports >50A non-repetitive I_TSM (8.3ms).
UL File	156346 - UL Recognized Component status confirms compliance with UL497B for primary protection in telecom interface circuits.

IC Role / Device Role / Timing Role: Primary crowbar protector placed before line transformer and receiver ICs; triggers within nanoseconds upon overvoltage.

Use Value: Clamps 100A surges while maintaining <120pF loading - preserves signal integrity up to 30MHz and prevents damage to sensitive PHY transceivers.

Use Scenario: Safeguarding IEEE 802.3af/at PSE controller inputs and sense resistors against Ethernet cable ESD and surge events.

IC Role / Device Role / Timing Role: Bidirectional shunt protector across DC feed lines; conducts fault current away from current-sense circuitry during miswiring or surge.

Use Value: 140V V_DRM allows operation on 57V max PSE output; 3.5V V_T limits power dissipation during 100A transients, avoiding thermal runaway.

Industrial Analog I/O Protection

Building Automation BMS Controllers

Use Scenario: Securing 4–20mA current loop inputs in PLC analog modules exposed to field wiring transients.

IC Role / Device Role / Timing Role: Standoff-mode protector placed across loop terminals; remains high-impedance until V_BO exceeded, then latches low-impedance state.

Use Value: <5μA leakage at 140V ensures minimal impact on loop accuracy; 30ms recovery guarantees return to normal operation after transient clears.

Use Scenario: Protecting RS-485 transceivers and microcontroller GPIOs in HVAC controllers connected to long building wiring runs.

IC Role / Device Role / Timing Role: Bidirectional line protector on differential bus lines; symmetric clamping prevents common-mode shift during surge events.

Use Value: 180V V_BO provides 40V margin above 120VAC-derived supply rails; SMB footprint enables 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
Littelfuse SP1003-014	V_DRM = 135V; I_PP = 100A (10/1000μs); C_O = 150pF; SMB package	Higher capacitance may degrade >10MHz signal integrity; identical thermal rating (R_θJL = 20°C/W)	Select when legacy Littelfuse design reuse is required; verify C_O impact on high-speed data lines.
Bourns TBU-CA120-200-WH	V_DRM = 120V; I_PP = 200A (8/20μs); active current-limiting architecture; SO-8 package	Lower V_DRM reduces operating margin; higher I_PP suits more severe surge environments; requires control logic	Prefer for systems needing programmable trip delay or coordination with secondary TVS; not drop-in due to different package and drive requirements.

Compared with SP1003-014 and TBU-CA120-200-WH, TB1500H-13-F offers optimal balance of 140V standoff margin, low 120pF capacitance, and proven passive crowbar behavior - making it ideal for cost-sensitive, high-volume telecom and industrial analog protection where simplicity and reliability are prioritized over programmability.

FAQ

What is the maximum continuous operating voltage for TB1500H-13-F?

The maximum repetitive off-state voltage (V_DRM) is 140V. This is the highest RMS or DC voltage the device can block continuously without triggering. Operation above this value risks unintended conduction. For 120VAC systems, this provides ~17% margin above peak line voltage (169.7V), satisfying standard derating guidelines for reliable long-term blocking.

Does TB1500H-13-F require a gate trigger or external circuitry to operate?

No. TB1500H-13-F is a passive, voltage-triggered thyristor device with no gate terminal. It relies solely on intrinsic junction characteristics: conduction initiates automatically when applied voltage exceeds its breakover voltage (V_BO = 180V typ.). No bias, control signal, or external components are needed - simplifying design and improving system-level reliability.

How does TB1500H-13-F compare to standard TVS diodes in surge protection?

TB1500H-13-F offers higher surge current handling (100A vs. typical 40–60A for SMB TVS) and lower clamping voltage variation under repeated surges due to its thyristor latching behavior. Unlike TVS diodes that clamp dynamically, it switches to a low-impedance state and holds until current drops below holding threshold (150–800mA), providing more predictable energy diversion in high-energy transients like lightning.

Is TB1500H-13-F compatible with lead-free reflow soldering processes?

Yes. TB1500H-13-F features matte tin-plated terminals and is qualified for lead-free reflow per JEDEC J-STD-020. Its moisture sensitivity level is Grade 1, meaning it can be stored indefinitely at ≤30°C/60% RH without baking. The SMB package withstands peak reflow temperatures up to 260°C, fully compatible with standard Pb-free SAC305 profiles.
