Product details

TB2600L-13 from Diodes Incorporated

TB2600L-13 from Diodes Incorporated is a bi-directional surface-mount thyristor surge protective device (TSPD) designed for AC line and telecom port protection. It features 220V stand-off voltage, 30A peak pulse current (10/1000μs), 150A peak pulse current (8/20μs), 40pF off-state capacitance, and 3.5V on-state voltage at 1A - enabling robust transient suppression in DSL, POTS, and PoE-powered Ethernet interfaces.

For engineers reviewing the TB2600L-13 datasheet, TB2600L-13 pinout, TB2600L-13 application, or TB2600L-13 equivalent, key selection criteria include verified bi-directional clamping behavior, junction temperature derating up to +150°C, thermal resistance (R_θJL = 30°C/W), and compatibility with UL 94V-0 SMB package reflow profiles.

Technical Context

This TSPD operates as a voltage-triggered crowbar device: it remains high-impedance below 220V (V_DRM), triggers at ~300V (V_BO), and latches into low-voltage conduction (<3.5V at 1A) until current falls below 150–800mA holding threshold (I_H). Its oxide-glass passivated junction ensures stable breakdown over -40°C to +150°C.

Unlike unidirectional TVS diodes, the TB2600L-13 provides symmetrical clamping for both polarities without external series components. Its 40pF off-state capacitance at 2V bias and 1MHz enables use in <10MHz signal paths without significant insertion loss.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DRM	220V - maximum continuous AC/DC voltage before triggering; sets minimum system operating margin
I_PP (10/1000μs)	30A - surge rating per GR-1089-CORE; defines survivability against lightning-induced surges
I_PP (8/20μs)	150A - IEC 61000-4-5 compliance level; validates protection against fast, high-energy transients
C_O	40pF - measured at 1MHz, 2V DC bias; ensures minimal signal distortion in broadband telecom lines
R_θJL	30°C/W - junction-to-lead thermal resistance; supports sustained 15A half-cycle surge without solder joint failure
V_T @ 1A	3.5V - on-state voltage drop; determines power dissipation (3.5W) during clamping event
I_H range	150–800mA - holding current window; defines minimum load current required to maintain latched state

Pinout & Package

Package: SMB (DO-214AA), surface-mount, UL 94V-0 molded plastic case, moisture sensitivity Level 1, weight 0.093g.

Pin/Terminal	Circuit Role	Design Meaning
Anode (A)	Trigger input / conduction path	Bi-directional terminal - functions identically as cathode under reverse polarity; no polarity marking required
Cathode (K)	Trigger input / conduction path	Same physical terminal as Anode due to symmetrical structure; terminals are interchangeable in layout

Key Features

Feature	Design Value
Bi-directional clamping	Single-device protection for AC lines and full-duplex data ports without polarity awareness or external diodes
Oxide-glass passivated junction	Stable V_BO drift ≤0.1%/°C and leakage <5μA up to 220V across full temperature range
High off-state impedance	Leakage current ≤5μA at rated V_DRM, minimizing standby power loss in always-on telecom equipment
SMB package compatibility	Standard footprint supports automated placement and IPC-7095-compliant reflow, eliminating custom land patterns

Applications

DSL Line Interface Protection

POTS Telephone Line Protection

Use Scenario: Protects ADSL/VDSL line cards from induced surges on twisted-pair copper loops exposed to lightning or power cross events.

IC Role / Device Role / Timing Role: Bi-directional crowbar that triggers within nanoseconds upon exceeding 300V, clamping line voltage to <3.5V while conducting >30A.

Use Value: Prevents damage to upstream line drivers and downstream PHY ICs; 40pF capacitance avoids signal integrity degradation at 30MHz.

Use Scenario: Shields analog telephone interface circuits (SLIC, codec) from FCC Part 68 surges (100A, 10/160μs) and accidental AC power contact.

IC Role / Device Role / Timing Role: Voltage-triggered latch that sustains conduction until ring signal ends or loop current drops below 150mA.

Use Value: Eliminates need for back-to-back TVS diodes; single SMB device reduces BOM count and PCB area by 50% vs. discrete solutions.

PoE-Powered Ethernet Port

Industrial AC Sensor Input

Use Scenario: Safeguards Power over Ethernet (IEEE 802.3af/at) data pairs against ESD and surge coupling from adjacent power conductors.

IC Role / Device Role / Timing Role: Standby protector with <5μA leakage at 57V nominal PoE voltage, triggering only during >300V transients.

Use Value: Maintains IEEE 802.3 compliance by adding <0.5dB insertion loss at 100MHz; R_θJL = 30°C/W prevents thermal runaway during repeated 150A surges.

Use Scenario: Protects 24VAC industrial sensor inputs (e.g., proximity switches, solenoid drivers) from switching transients and ground potential differences.

IC Role / Device Role / Timing Role: High-impedance guard during normal operation; latches on 220V+ surges and resets automatically when load current falls below 800mA.

Use Value: Enables direct connection to 24VAC lines without series resistors or Zener clamps; 150°C max junction temperature supports enclosure mounting near heat sources.

Equivalent & Alternatives

The following parts are listed as comparable options for similar bi-directional surge protection applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Littelfuse SP1003-02HT	Unidirectional, 200V V_DRM, 100A I_PP (8/20μs), 150pF C_O	Requires dual-device configuration for AC lines; higher capacitance limits use above 2MHz	Select when higher 8/20μs surge rating is prioritized over signal bandwidth
Bourns TISP4240M3JR-S	Bi-directional, 240V V_DRM, 100A I_PP (8/20μs), 60pF C_O, TO-220 package	Larger through-hole package; higher thermal mass but incompatible with SMT-only assembly	Select when board-level heat sinking is available and 100A surge headroom justifies manual assembly

Compared with SP1003-02HT and TISP4240M3JR-S, the TB2600L-13 offers optimal balance of SMB footprint, 40pF low capacitance, and 220V/30A rating - making it preferred for space-constrained, high-frequency telecom and PoE designs where automated assembly is mandatory.

FAQ

What is the maximum allowable junction temperature during surge conduction?

The TB2600L-13 is rated for junction temperatures from –40°C to +150°C. During a 30A, 10/1000μs surge, peak junction temperature rise is limited to ≤45°C above ambient (calculated using R_θJL = 30°C/W and 3.5V × 30A × 1ms energy), well within safe operating limits.

Does TB2600L-13 require a series current-limiting resistor?

No. The device is designed to latch and hold during surge events without external current limiting. However, a series resistor may be used to ensure load current remains above the 150–800mA holding threshold (I_H) during clamping - critical for reliable reset after surge clearance.

How does off-state capacitance affect high-speed data lines?

With 40pF off-state capacitance measured at 1MHz and 2V bias, the TB2600L-13 introduces negligible attenuation below 10MHz. At 100MHz, capacitive reactance is ~40Ω, resulting in <0.5dB insertion loss in 100Ω differential lines - compliant with Category 5e/6 Ethernet and VDSL2 spectral masks.

Can TB2600L-13 be used in DC-only applications?

Yes. Though optimized for AC line protection, its bi-directional symmetry and 220V V_DRM make it suitable for bidirectional DC bus protection (e.g., CAN FD, RS-485, or redundant power rails), provided the holding current condition (I_H > load current during fault) is satisfied for automatic reset.
