Product details
Overview
TB2600M-13 from Diodes Incorporated is a bi-directional surface-mount thyristor surge protective device (TSPD) designed for primary-level AC/DC line transient suppression in telecom and industrial power interfaces. It features 220V stand-off voltage (VDRM), 300V breakover voltage (VBO), 50A 10/1000μs peak pulse current (Ipp), 250A 8/20μs surge rating, and 60pF off-state capacitance - enabling robust GR-1089-CORE and IEC 61000-4-5 compliance in DSL, POTS, and PoE-powered equipment.
For engineers reviewing the TB2600M-13 datasheet, TB2600M-13 pinout, TB2600M-13 application, or TB2600M-13 equivalent, this device delivers verified bi-directional clamping with low leakage (5μA at VDRM), stable thermal performance (RJL = 20°C/W), and SMB package compatibility for high-density PCB layouts in telecom line card and base station front-end protection.
Technical Context
This TSPD operates as a voltage-triggered crowbar device: it remains high-impedance below VDRM (220V), transitions to low-impedance conduction at VBO (300V ±15%), and sustains on-state voltage ≤3.5V at 1A. Its bi-directional symmetry eliminates polarity concerns in AC-coupled lines.
Thermal design relies on junction-to-lead resistance (20°C/W) and 150°C max junction temperature, while holding current (150–800mA) ensures reliable recovery post-surge without latch-up - critical for repeated surge events in FCC Part 68-compliant subscriber line interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM | 220V - maximum continuous reverse/forward blocking voltage before triggering |
| VBO | 300V - DC breakover threshold initiating crowbar conduction |
| Ipp (10/1000μs) | 50A - peak surge current handling per GR-1089-CORE Level 3 |
| CO | 60pF - low junction capacitance minimizing signal distortion in broadband telecom lines |
| IDRM | 5μA - ultra-low leakage at rated stand-off voltage, preserving line integrity |
| RJL | 20°C/W - enables direct thermal coupling to PCB copper for efficient surge energy dissipation |
| ITSM | 30A - non-repetitive half-cycle on-state current rating (8.3ms, 60Hz) |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bi-directional, polarity-free. Dimensions: 4.06–4.57mm (L) × 3.30–3.94mm (W) × 1.96–2.21mm (H). UL 94V-0 molded plastic case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (A/K) | Bi-directional main terminals | Interchangeable; no polarity marking required - symmetric conduction in AC or DC surge paths |
| Case | Non-electrical mechanical interface | UL 94V-0 thermoplastic housing; no internal connection to silicon die |
Key Features
| Feature | Design Value |
|---|---|
| Oxide-glass passivated junction | Ensures stable VBO over temperature and lifetime, with <0.1%/°C drift |
| High off-state impedance + low on-state voltage | 5μA leakage at 220V + ≤3.5V VT at 1A enables minimal power loss during clamping |
| Bi-directional single-device protection | Replaces dual-diode or MOV+TVS solutions in AC line inputs, reducing BOM count and layout area |
| GR-1089-CORE / IEC 61000-4-5 certified | Validated for Level 3 (50A 10/1000μs) and Level 4 (250A 8/20μs) telecom surge immunity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional TSPD surge protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220CA | TVS diode array; 220V standoff, 356V breakdown, 100A 8/20μs rating, 180pF CO | Higher capacitance limits use in >10MHz lines; faster response but lower surge endurance | Select when sub-nanosecond clamping speed is prioritized over long-duration surge absorption |
| TB2300M-13 | 190V VDRM, 265V VBO, identical SMB package and thermal specs | Lower voltage rating suits 170–200VAC mains-derived supplies or legacy telecom lines | Choose for cost-sensitive designs where 220V standoff margin is unnecessary |
Compared with SMBJ220CA, TB2600M-13 offers 3× lower capacitance and superior 10/1000μs energy handling; versus TB2300M-13, it provides higher voltage headroom for next-gen 240VAC-compatible telecom infrastructure.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The TB2600M-13 has a specified junction temperature range of –40°C to +150°C. For continuous operation under DC or repetitive surge conditions, thermal design must ensure TJ does not exceed +150°C, using RJL = 20°C/W and PCB copper area as the primary heat path. Derating applies above +125°C ambient.
Does TB2600M-13 require a series current-limiting resistor?
No external series resistor is required for standard surge suppression. The device's intrinsic holding current (150–800mA) and on-state voltage (≤3.5V) ensure self-quenching after surge decay. However, a resistor may be added to limit follow current in high-voltage AC applications exceeding 220V RMS.
How does off-state capacitance affect high-frequency signal integrity?
At 60pF, TB2600M-13 introduces negligible insertion loss below 30MHz in typical 100Ω telecom lines. Measured at 1MHz/2VDC bias, its capacitance remains stable across temperature and voltage, making it suitable for VDSL2 and G.fast line interfaces where signal fidelity is critical.
Can TB2600M-13 be used in DC-only applications like battery backup circuits?
Yes - its bi-directional structure functions identically on DC lines. It clamps positive surges relative to ground and negative surges relative to VCC, provided the DC rail voltage remains below VDRM (220V). It is commonly deployed on 48V DC PoE and telecom battery feeds.
