Product details
Overview
TB2300L-13 from Diodes Incorporated is a bi-directional surface-mount thyristor surge protective device (TSPD) with 190V stand-off voltage, 30A peak pulse current (10/1000μs), and 150A peak pulse current (8/20μs), designed for primary-level overvoltage protection in telecom line interfaces, AC power inputs, and industrial control I/O circuits.
For engineers reviewing the TB2300L-13 datasheet, TB2300L-13 pinout, TB2300L-13 application, or TB2300L-13 equivalent, key selection criteria include off-state capacitance (40 pF), breakover voltage (265 V), holding current range (150–800 mA), thermal resistance (30 °C/W junction-to-lead), and SMB package compatibility with automated SMT assembly.
Technical Context
This TSPD operates as a voltage-triggered crowbar device: it remains high-impedance below 190V (VDRM), transitions to low-impedance conduction at 265V (VBO), and latches on until current falls below 150–800 mA (IH). Its oxide-glass passivated junction ensures stable triggering across -40°C to +150°C junction temperature.
Bi-directional symmetry enables single-device protection of AC lines without polarity concerns; off-state capacitance of 40 pF minimizes signal distortion in high-frequency telecom applications, while 30 °C/W RθJL supports reliable power dissipation during repetitive surges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM | 190 V - Maximum continuous reverse/forward voltage before leakage exceeds 5 µA |
| VBO | 265 V - Breakover voltage threshold initiating conduction under surge conditions |
| IPP (10/1000µs) | 30 A - Peak surge current handling for long-duration lightning-induced transients |
| IPP (8/20µs) | 150 A - Peak surge current handling for fast-rising utility or EFT events |
| CO | 40 pF - Low off-state capacitance preserves signal integrity up to ~100 MHz |
| RθJL | 30 °C/W - Enables efficient heat transfer to PCB copper, critical for repeated surge duty |
| IH | 150–800 mA - Minimum current required to sustain conduction; defines recovery behavior post-surge |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, UL 94V-0 molded plastic case, no polarity indicator due to bi-directional symmetry.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (A/K) | Bi-directional main terminals | Interchangeable; either terminal serves as anode or cathode depending on transient polarity |
| Case | Non-electrical mechanical reference | No internal connection; serves only as thermal path and mechanical anchor |
Key Features
| Feature | Design Value |
|---|---|
| Oxide-glass passivated junction | Ensures stable, repeatable breakover voltage with <0.1 %/°C tempco and minimal parameter drift over life |
| Bi-directional protection in single device | Eliminates need for back-to-back diode or dual-TSPD layout, reducing board area by ≥40% |
| High off-state impedance (>1 GΩ @ 190 V) | Prevents standby power loss and false triggering in always-on systems |
| Low on-state voltage (3.5 V @ 1 A) | Minimizes clamping energy dissipation during surge, reducing thermal stress on PCB traces |
Applications
| DSL Line Interface Protection | AC Power Input Surge Suppression |
|---|---|
Use Scenario: Protecting ADSL/VDSL line cards from induced lightning surges on twisted-pair copper lines. IC Role / Device Role / Timing Role: Primary crowbar protector placed before line transformer and receiver IC. Use Value: 40 pF capacitance avoids signal attenuation above 1 MHz; 265 V VBO coordinates with secondary TVS clamping at 24 V. | Use Scenario: Safeguarding AC-DC adapter inputs against line-switching transients and indirect lightning. IC Role / Device Role / Timing Role: First-stage surge limiter upstream of bridge rectifier and fuse. Use Value: 150 A (8/20 µs) rating handles IEC 61000-4-5 Level 4 surges; SMB footprint allows direct replacement of legacy MOVs. |
| Industrial PLC Digital I/O Protection | Smart Meter Communication Port Protection |
Use Scenario: Shielding 24 V DC digital input channels from inductive kickback and ground potential differences. IC Role / Device Role / Timing Role: Bi-directional clamp between signal line and chassis ground. Use Value: 190 V VDRM tolerates normal 24 V ±20% variation plus ripple; 30 °C/W RθJL sustains repeated 10/1000 µs surges without thermal runaway. | Use Scenario: Securing RS-485 or HPLC communication ports in electricity meters exposed to grid noise. IC Role / Device Role / Timing Role: Standoff protector on differential bus lines, coordinated with common-mode chokes. Use Value: Symmetrical bi-directional response prevents polarity-dependent failure; 150–800 mA IH ensures clean recovery after meter reset cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional thyristor surge protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ190CA | Unidirectional TVS diode; 190 V standoff, but no latching behavior or holding current | Lacks crowbar action; relies on system current limiting to clear surge | Choose when lower clamping voltage (≈215 V) is prioritized over self-sustaining conduction |
| TB2600L-13 | Higher 220 V VDRM and 300 V VBO; otherwise identical SMB package and thermal specs | Better suited for 230 VAC mains interfaces where higher standoff margin is required | Select when protecting circuits operating near 200–220 V nominal with tighter safety margins |
Compared with TB2300L-13, SMBJ190CA offers faster response but no current-holding capability-requiring external current limiting-while TB2600L-13 provides higher voltage margin without changing layout or thermal design.

FAQ
What is the maximum allowable surge repetition rate for TB2300L-13?
TB2300L-13 has no specified maximum repetition rate in its datasheet; however, thermal recovery requires ≥1 second between 30 A (10/1000 µs) surges to prevent junction temperature exceeding +150°C, based on RθJL = 30 °C/W and typical surge energy of 1.2 J. For higher repetition, derating or heatsinking is mandatory.
Does TB2300L-13 require a gate trigger circuit?
No. TB2300L-13 is a three-layer, gateless thyristor that triggers solely via voltage-dependent avalanche breakdown at the junction. It requires no external gate drive, biasing, or control signals-conduction initiates automatically when applied voltage exceeds 265 V (VBO) under specified dV/dt conditions.
How does TB2300L-13 behave after a surge event?
After triggering, TB2300L-13 latches into low-impedance conduction and remains on until load current drops below its holding current (150–800 mA). Recovery to high-impedance state occurs within ≤30 ms once current falls below IH, verified per datasheet Note 1 and Fig. 5's junction temperature dependency.
Can TB2300L-13 be used in DC-only circuits?
Yes. Although bi-directional, TB2300L-13 functions identically in DC circuits: it blocks up to 190 V in either polarity and triggers at 265 V across its terminals. In DC, it acts as a unidirectional crowbar-once triggered, it conducts until current interruption (e.g., by fuse or current-limiting resistor) forces recovery.
