Product details
Overview
TB2300H-13 from Diodes Incorporated is a bidirectional surface-mount thyristor surge protective device (TSPD) designed for primary-level overvoltage protection in telecom and data line interfaces. It features a 190V stand-off voltage (VDRM), 265V breakover voltage (VBO), 100A peak pulse current (10/1000μs), 400A peak pulse current (8/20μs), and 80pF off-state capacitance - enabling robust transient suppression in DSL, T1/E1, and PoE-powered Ethernet ports.
For engineers reviewing the TB2300H-13 datasheet, TB2300H-13 pinout, TB2300H-13 application, or TB2300H-13 equivalent, key selection criteria include stand-off voltage margin vs. line operating voltage, peak pulse current rating under IEC 61000-4-5, off-state capacitance impact on high-speed signal integrity, and thermal resistance (RθJL = 20°C/W) for sustained surge duty cycles.
Technical Context
This bidirectional TSPD operates as a voltage-triggered crowbar device: it remains in high-impedance off-state until transient voltage exceeds VBO (265V), then latches into low-voltage on-state (VT ≤ 3.5V @ 1A) to shunt surge energy. Its oxide-glass passivated junction ensures stable breakdown characteristics across temperature (ΔVBR/ΔTJ = 0.1%/°C).
Designed for GR-1089-CORE, IEC 61000-4-5, and ITU-T K.20/K.21 compliance, it delivers 400A surge handling at 8/20μs while maintaining <5μA leakage at 190V and holding current (IH) between 150–800mA - ensuring reliable reset after transient clearance without follow-on current issues.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM | 190V - maximum continuous working voltage before triggering; sets minimum system operating margin for protected lines. |
| VBO | 265V - guaranteed breakover threshold; defines clamping onset point for fast transients. |
| Ipp (10/1000μs) | 100A - surge current capability per GR-1089-CORE; determines survivability against lightning-induced surges. |
| Ipp (8/20μs) | 400A - higher-energy surge rating per IEC 61000-4-5; supports industrial-grade immunity testing. |
| CO | 80pF - off-state capacitance at 1MHz/2VDC bias; enables use in ≤100Mbps data lines without excessive signal attenuation. |
| RθJL | 20°C/W - junction-to-lead thermal resistance; allows direct PCB copper pour heat sinking for repeated surge events. |
| IH Range | 150–800mA - holding current window; ensures reliable turn-off after surge when load current drops below lower bound. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional - no polarity marking required. Molded plastic case rated UL 94V-0; weight ≈ 0.093g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (A/K) | Bidirectional main terminals | Interchangeable; symmetric structure enables identical protection for both polarities of AC or differential signals. |
| Case | Non-electrical mechanical interface | No internal connection; serves only as thermal path and mechanical anchor - not a functional pin. |
Key Features
| Feature | Design Value |
|---|---|
| Oxide-glass passivated junction | Ensures stable VBO and low leakage (<5μA) across -40°C to +150°C junction temperature range. |
| Bidirectional single-device protection | Eliminates need for back-to-back diac or dual-TSPD layout; reduces PCB area and BOM count by 50%. |
| High off-state impedance / low on-state voltage | Minimizes standby power loss and signal distortion while delivering <3.5V clamping during conduction. |
| UL Recognized Component (File E156346) | Validates safety compliance for end-equipment certification without additional system-level testing overhead. |

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 SP1003-010 | 100V VDRM, 120A Ipp (10/1000μs), SMB package, 100pF CO | Lower stand-off voltage limits use to sub-70V systems; higher capacitance restricts >50Mbps data rates | Select when protecting lower-voltage analog or legacy telecom lines where 190V margin is excessive. |
| Bourns TBU-CA065-200-WH | 65V VDRM, 200A Ipp (8/20μs), SOT-23 package, 35pF CO | Unidirectional; requires external diode pairing for AC line protection; smaller footprint but lower surge rating | Prefer for space-constrained, low-voltage DC bias applications where bidirectionality is handled externally. |
Compared with SP1003-010 and TBU-CA065-200-WH, TB2300H-13 offers superior voltage margin for modern telecom lines, higher 8/20μs surge capacity, and true single-device bidirectionality - making it optimal for DSL, T1/E1, and PoE port protection where system voltage and surge severity demand robust, symmetric clamping.

FAQ
What is the maximum junction temperature and storage temperature range for TB2300H-13?
TB2300H-13 has a junction temperature range of –40°C to +150°C and a storage temperature range of –55°C to +150°C. These ratings are validated per JEDEC JESD22-A103 and ensure reliable operation in harsh environments such as outdoor telecom cabinets and industrial control panels.
Does TB2300H-13 require a gate trigger or external control circuit?
No - TB2300H-13 is a passive, voltage-triggered thyristor device with no gate terminal. It operates autonomously: conduction initiates when applied voltage exceeds VBO (265V), and it remains latched until load current falls below IH (150–800mA). No external bias or driver circuitry is needed.
How does the 80pF off-state capacitance affect high-speed data line performance?
At 80pF, TB2300H-13 introduces minimal insertion loss below 100MHz, making it suitable for VDSL2 (up to 30MHz), T1 (1.544MHz), and 10/100BASE-TX Ethernet. Measured at 1MHz/2VDC bias, this capacitance remains stable across temperature and does not degrade eye diagrams in compliant line-driver designs.
Is TB2300H-13 compatible with lead-free reflow soldering processes?
Yes - TB2300H-13 features matte tin-plated terminals and is rated for lead-free reflow per JEDEC J-STD-020, with moisture sensitivity level (MSL) 1. It withstands peak temperatures up to 260°C for 30 seconds and is fully RoHS compliant (EU Directive 2002/95/EC) with halogen-free molding compound.
