Product details
Overview
TB0640H-13-F from Diodes Incorporated is a bidirectional surface-mount thyristor surge protective device (TSPD) designed for primary-level overvoltage clamping in telecom and data line interfaces. It features a 58 V stand-off voltage, 100 A peak pulse current (10/1000 µs), 77 V breakover voltage, 3.5 V on-state voltage at 1 A, and 200 pF off-state capacitance - enabling robust protection of DSL, T1/E1, and analog telephone line circuits against GR-1089-CORE and IEC 61000-4-5 transients.
For engineers reviewing the TB0640H-13-F datasheet, TB0640H-13-F pinout, TB0640H-13-F application, or TB0640H-13-F equivalent, key selection criteria include stand-off voltage matching, peak pulse current rating, off-state capacitance impact on signal integrity, and SMB package compatibility with high-density PCB layouts in telecom front-end protection stages.
Technical Context
This bidirectional TSPD operates as a voltage-triggered crowbar device: it remains in high-impedance off-state until transient voltage exceeds its 77 V breakover threshold, then latches into low-voltage conduction (≤3.5 V) to shunt surge energy. Its oxide-glass passivated junction ensures stable triggering across temperature (-40°C to +150°C).
With no polarity indicator and symmetric I-V characteristics, it protects AC-coupled lines without orientation constraints. The device sustains 50 A non-repetitive on-state current (8.3 ms half-sine) and recovers to high-impedance state within ≤30 ms after surge clearance, provided holding current criterion (IH > VL/RL) is met.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VDRM) | 58 V - maximum continuous operating voltage before conduction begins; sets protection threshold for normal line operation. |
| Breakover Voltage (VBO) | 77 V - precise voltage at which device triggers into low-impedance state; defines clamping initiation point for surges. |
| Peak Pulse Current (Ipp) | 100 A @ 10/1000 µs - surge-handling capacity for long-duration lightning-induced transients per GR-1089-CORE. |
| On-State Voltage (VT) | 3.5 V @ 1 A - low clamping voltage during conduction; minimizes power dissipation and downstream component stress. |
| Off-State Capacitance (CO) | 200 pF @ 1 MHz, 2 VDC bias - directly impacts high-frequency signal attenuation and bandwidth in DSL/analog voice lines. |
| Holding Current (IH) | 150–800 mA - minimum current required to maintain conduction; critical for ensuring clean recovery post-surge. |
| Thermal Resistance (RθJL) | 20 °C/W - enables efficient heat transfer from junction to lead; supports sustained reliability under repeated surge events. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional, polarity-free case with matte tin-plated terminals. Dimensions: 3.30–3.94 mm (A) × 4.06–4.57 mm (B) × 1.96–2.21 mm (C); weight ≈ 0.093 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Surge conduction path | Identical terminals enable bidirectional clamping; no marking or polarity - simplifies layout and eliminates orientation errors. |
| Case (cathode-side metal tab) | Thermal and electrical reference | Exposed cathode-side metallization serves as thermal sink and low-inductance return path for surge current. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional protection in single device | Eliminates need for back-to-back diode or dual-TSPD arrangements in AC-coupled telecom lines. |
| Oxide-glass passivated junction | Ensures stable VBO tolerance (±5%) and long-term reliability under humidity and thermal cycling. |
| UL Recognized Component (File E156346) | Validates compliance for use in end-equipment requiring UL497B certification for telecom surge protection. |
| Lead-free & halogen-free construction | Meets RoHS Directive 2002/95/EC and JEDEC J-STD-020 moisture sensitivity Level 1 requirements. |
Applications
| DSL Line Protection | T1/E1 Interface Protection |
|---|---|
Use Scenario: Protecting ADSL/VDSL line cards from induced lightning surges and AC power cross-talk on twisted-pair copper loops. IC Role / Device Role / Timing Role: Primary crowbar-type surge protector placed upstream of line transformer and codec IC. Use Value: 58 V VDRM matches typical DSL line DC bias; 200 pF CO avoids degrading uplink/downlink signal integrity above 1 MHz. | Use Scenario: Safeguarding T1/E1 framer and line driver ICs in telecom central office and CPE equipment against longitudinal surges. IC Role / Device Role / Timing Role: First-stage transient suppressor on balanced receive/transmit pairs before isolation transformers. Use Value: 100 A Ipp (10/1000 µs) meets GR-1089-CORE Level 3 requirements; bidirectional symmetry handles differential-mode surges without polarity concerns. |
| Analog Telephone Line (POTS) | ISDN BRI Protection |
Use Scenario: Overvoltage protection for subscriber line interface circuits (SLIC) and ringing generators in analog telephony systems. IC Role / Device Role / Timing Role: Standby-mode protector across tip/ring lines, triggered only during fault conditions. Use Value: Low 5 µA IDRM at 58 V ensures minimal standby leakage; 30 ms recovery time prevents latch-up during repetitive ring signals. | Use Scenario: Surge suppression on ISDN Basic Rate Interface (2B+D) U-interface lines exposed to outdoor cabling. IC Role / Device Role / Timing Role: Bidirectional clamp on both B-channels and D-channel, mounted before line termination resistors. Use Value: 77 V VBO provides margin above 100 V peak ring voltage while clamping fast 8/20 µs surges up to 400 A. |
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 SP1003-058 | Same 58 V VDRM and SMB package; higher 150 A Ipp (10/1000 µs); 180 pF CO. | Better suited for higher-energy lightning zones; lower capacitance improves high-speed data line performance. | Select when system-level testing requires >100 A surge margin or tighter CO spec for >2 Mbps DSL. |
| Bourns TISP4240H3BJR-S | 58 V VDRM, but SOT-23-6 package; 100 A Ipp; 150 pF CO; integrated trigger circuitry. | Requires PCB redesign due to different footprint and pin count; optimized for space-constrained consumer modems. | Choose for compact designs where SMB real estate is unavailable and integrated trigger control is preferred. |
Compared with SP1003-058 and TISP4240H3BJR-S, TB0640H-13-F offers proven field reliability in telecom infrastructure, standardized SMB mounting, and optimal balance of clamping voltage, surge rating, and capacitance for legacy and hybrid voice/data line cards.

FAQ
What is the maximum continuous operating voltage for TB0640H-13-F?
The maximum rated repetitive off-state voltage (VDRM) is 58 V. This is the highest DC or RMS AC voltage the device can block continuously without triggering. Operation above this level risks premature conduction and potential damage, especially under elevated temperature or prolonged stress.
Does TB0640H-13-F require external trigger circuitry?
No. TB0640H-13-F is a self-triggering bidirectional thyristor - it conducts automatically when applied voltage exceeds its 77 V breakover voltage (VBO). No gate drive, biasing, or auxiliary components are needed, simplifying protection circuit design and reducing BOM count.
How does off-state capacitance affect its use in high-speed data lines?
Its 200 pF off-state capacitance introduces insertion loss and group delay above ~1 MHz. In ADSL2+ or VDSL2 systems, this limits usable bandwidth and may require compensation in line driver design. For >10 Mbps applications, alternatives with ≤120 pF (e.g., TB1100H series) are recommended.
Can TB0640H-13-F be used in automotive applications?
No. TB0640H-13-F is not qualified to AEC-Q101 and lacks automotive-grade screening, temperature derating, or failure mode documentation. Its design targets telecom infrastructure - not automotive CAN/LIN bus or infotainment interfaces - and is not rated for 105°C ambient or load-dump transient profiles.
