Product details
Overview
TB3100H-13-F from Diodes Incorporated is a bidirectional surface-mount thyristor surge protective device (TSPD) designed for telecom and data line overvoltage clamping. It features a 275V maximum repetitive off-state voltage (VDRM), 350V breakover voltage (VBO), 100A peak pulse current at 10/1000μs, 400A at 8/20μs, and 80pF off-state capacitance - enabling robust GR-1089-CORE and IEC 61000-4-5 compliance in DSL, T1/E1, and PoE interface protection.
For engineers reviewing the TB3100H-13-F datasheet, TB3100H-13-F pinout, TB3100H-13-F application, or TB3100H-13-F equivalent, key selection criteria include stand-off voltage margin vs. system operating voltage, bidirectional clamping symmetry, low off-state capacitance for high-speed signal integrity, and SMB package thermal performance under repeated surge stress.
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 across temperature (±0.1%/°C drift), while high off-state impedance (>100MΩ at 275V) minimizes standby leakage in protected lines.
It latches into low-impedance on-state during overvoltage events and recovers within ≤30ms after surge removal. Holding current (IH) ranges 150–800mA, ensuring reliable reset only when line current falls below threshold - critical for maintaining signal continuity post-surge in powered interfaces like PoE PSE/PD ports.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM | 275V - Maximum continuous AC/DC working voltage before conduction; sets minimum system operating margin for DSL line drivers. |
| VBO | 350V - Breakover voltage threshold where device triggers into low-impedance state; defines clamping onset for transient suppression. |
| Ipp (10/1000μs) | 100A - Peak surge current handling per IEEE/IEC standard waveform; determines survivability against lightning-induced surges. |
| Ipp (8/20μs) | 400A - Higher-energy surge rating per IEC 61000-4-5; supports robust front-end protection in central office equipment. |
| CO | 80pF - Off-state capacitance at 2V bias and 1MHz; enables <1% signal attenuation up to 100MHz in xDSL applications. |
| RθJA | 100°C/W - Junction-to-ambient thermal resistance in SMB package; informs derating for >1W average power dissipation in sustained fault conditions. |
| IDRM | 5μA - Max leakage at rated VDRM; ensures negligible DC loading on high-impedance analog or digital receive paths. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional - no polarity marking required. Molded plastic case meets UL 94V-0; terminals are matte tin-plated for RoHS-compliant soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Surge current path | Identical terminals enable bidirectional clamping without orientation constraints; both pins conduct equally during positive or negative transients. |
| Case | Thermal and mechanical anchor | Exposed copper pad on underside provides primary heat path to PCB; requires ≥10mm² copper pour for RθJA ≤100°C/W. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional protection in single device | Eliminates need for back-to-back diac or dual-TSPD layout; reduces BOM count and PCB area by 50% in balanced line protection. |
| Oxide-glass passivated junction | Ensures VBO stability across -40°C to +150°C; avoids false triggering or failure due to thermal drift in outdoor telecom cabinets. |
| UL Recognized Component (File E156346) | Validates compliance for end-equipment safety certification; removes need for additional system-level surge validation testing. |
| Green molding compound (halogen-free) | Meets IPC-4101D/21 and JEDEC J-STD-020 moisture sensitivity Level 1; enables standard reflow without baking or special handling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional surge protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ27CA | Unidirectional TVS; 27V standoff, 400W peak power; no holding current or latching behavior. | Requires dual-device configuration for bidirectional protection; higher capacitance (150pF) limits use above 20MHz. | Select when fast response (<1ps) and non-latching clamping are preferred over self-reset capability. |
| P6SMB33CA | Unidirectional TVS; 33V standoff, 600W peak power; no thermal latch mechanism or controlled recovery. | Lacks surge endurance beyond single-event rating; not validated for GR-1089-CORE multi-pulse testing. | Choose for cost-sensitive consumer-grade Ethernet ports where multi-surge resilience is not required. |
Compared with SMBJ27CA and P6SMB33CA, TB3100H-13-F delivers true bidirectional latching behavior, guaranteed multi-pulse survivability, and lower capacitance - making it uniquely suitable for carrier-grade telecom line cards requiring zero downtime after repeated surges.

FAQ
What is the maximum continuous operating voltage for TB3100H-13-F?
The maximum repetitive off-state voltage (VDRM) is 275V DC or RMS. This is the highest steady-state voltage the device can block without triggering. Operation above this level risks unintended conduction; system design must ensure normal-mode voltage remains at least 20% below VDRM to accommodate tolerance and transients.
Does TB3100H-13-F require external gate control or biasing?
No. TB3100H-13-F is a three-layer, gate-less thyristor structure that triggers solely based on voltage across its terminals. It has no gate pin or control input - conduction initiates automatically when voltage exceeds VBO (350V typical), and it remains latched until line current falls below the holding current (150–800mA).
How does TB3100H-13-F compare to standard TVS diodes in surge response time?
TB3100H-13-F has a typical response time of <10ns - comparable to silicon TVS diodes - but differs fundamentally in conduction behavior: once triggered, it latches into low-impedance state until current drops below IH, whereas TVS diodes return immediately after transient decay. This makes it superior for sustained overvoltage events.
Can TB3100H-13-F be used in AC mains applications?
No. TB3100H-13-F is rated for telecom/data line protection only, with VDRM = 275V and thermal limits suited for low-energy surges. It lacks the isolation, creepage, and safety certifications required for direct AC mains connection (e.g., 120/230VAC systems); use only in SELV circuits per IEC 62368-1.
