Product details
Overview
TB3500H-13-F from Diodes Incorporated is a bidirectional surface-mount thyristor surge protective device (TSPD) designed for primary-level AC/DC line protection in telecom and industrial interfaces. It features a 320V stand-off voltage, 100A peak pulse current (10/1000μs), 400A peak pulse current (8/20μs), 3.5V on-state voltage at 1A, and 80pF off-state capacitance - enabling robust transient suppression in DSL, POTS, and PoE-powered equipment.
For engineers reviewing the TB3500H-13-F datasheet, TB3500H-13-F pinout, TB3500H-13-F application, or TB3500H-13-F equivalent, key selection criteria include stand-off voltage matching (320V), bidirectional clamping capability, low capacitance for high-frequency signal integrity, and UL 497B/IEC 61000-4-5 compliance for telecom surge immunity testing.
Technical Context
This TSPD operates as a voltage-triggered, self-resetting crowbar device with symmetrical bidirectional conduction. Its oxide-glass passivated junction ensures stable breakover voltage (400V typical) and low leakage (<5μA at 320V), while the positive temperature coefficient of breakdown voltage (+0.1%/°C) supports thermal stability across –40°C to +150°C junction range.
The device sustains non-repetitive surge currents up to 100A (10/1000μs) and 400A (8/20μs), with holding current specified between 150–800mA and breakover current between 50–800mA - ensuring reliable latching and recovery within ≤30ms after surge clearance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VDRM) | 320V - maximum continuous operating voltage before conduction; sets minimum line voltage compatibility for AC/DC interfaces. |
| Peak Pulse Current (Ipp) | 100A @ 10/1000μs - defines surge handling capacity per GR-1089-CORE; determines survivability against lightning-induced surges. |
| Breakover Voltage (VBO) | 400V typical - voltage threshold initiating conduction; provides margin above VDRM to avoid false triggering. |
| On-State Voltage (VT) | 3.5V @ 1A - forward voltage drop during clamping; impacts power dissipation and thermal design under fault conditions. |
| Off-State Capacitance (CO) | 80pF @ 1MHz, 2VDC bias - limits high-frequency signal attenuation; critical for maintaining DSL/PoE data integrity. |
| Holding Current (IH) | 150–800mA - minimum current required to sustain conduction; ensures clean reset after surge removal. |
| Thermal Resistance (RθJA) | 100°C/W - junction-to-ambient thermal resistance; informs PCB copper area and airflow requirements for sustained surge duty. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional, polarity-free case with matte tin-plated terminals. Dimensions: 4.3mm × 3.6mm × 2.2mm (L × W × H), UL 94V-0 molded plastic body, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (A/K) | Bidirectional main terminals | No polarity designation; either terminal serves as anode or cathode depending on transient polarity - enables single-device protection of differential lines. |
| Case | Non-electrical mechanical interface | Insulated plastic housing; no electrical connection - eliminates ground loop risk and simplifies layout in isolated systems. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional surge clamping | Enables single-component protection of balanced telecom lines (e.g., tip/ring, differential Ethernet pairs) without external polarity management. |
| Oxide-glass passivated junction | Ensures long-term parameter stability and low leakage drift over temperature and lifetime - critical for field-deployed infrastructure. |
| UL 497B recognition | Validates suitability for primary-side protection in telephone network interface units (NIUs), DSLAMs, and VoIP gateways per safety standards. |
| Lead-free & halogen-free construction | Complies with RoHS Directive 2002/95/EC and JEDEC J-STD-020 moisture sensitivity Level 1 - supports automated assembly and environmental compliance. |
Applications
| DSL Line Interface Protection | POTS Telephone Line Protection |
|---|---|
Use Scenario: Protects ADSL/VDSL line cards from lightning-induced surges on twisted-pair copper loops. IC Role / Device Role / Timing Role: Primary crowbar-type surge protector placed before line transformer and codec IC. Use Value: 80pF capacitance minimizes high-frequency insertion loss; 320V VDRM matches typical POTS loop voltage swing. | Use Scenario: Shields analog telephone interface circuits (e.g., SLIC, codec) from induced transients on legacy PSTN lines.

Use Value: 100A 10/1000μs rating handles worst-case Ethernet cable ESD coupling; low leakage avoids false PSE detection faults. | Use Scenario: Protects RS-485/RS-422 transceivers and PLC I/O modules connected to long outdoor sensor cables. IC Role / Device Role / Timing Role: First-stage transient suppressor mounted at connector entry point before TVS diode array or signal conditioner. Use Value: 320V VDRM accommodates 24V/48V industrial bus common-mode swings; SMB package allows dense routing near connectors. |
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 SP1003-032 | 320V VDRM, 100A Ipp (10/1000μs), but 120pF CO - higher capacitance limits use in >10MHz signal paths. | Approved for UL 497B and IEC 61000-4-5, but lacks GR-1089-CORE validation. | Select when lower cost or alternate supply chain is prioritized over DSL signal integrity. |
| Bourns TISP4240M3JR | 320V VDRM, 100A Ipp, but 100pF CO and 4.5V VT - higher clamping voltage increases stress on downstream ICs. | Qualified for ITU-T K.21 and FCC Part 68, but not UL 497B listed. | Prefer for North American telecom POTS applications where UL listing is not mandatory. |
Compared with SP1003-032 and TISP4240M3JR, TB3500H-13-F delivers lower off-state capacitance (80pF) and tighter on-state voltage (3.5V), making it optimal for high-bandwidth DSL and PoE applications where signal fidelity and clamping efficiency are critical.

FAQ
What is the maximum operating temperature for TB3500H-13-F?
The junction temperature range is –40°C to +150°C, with thermal resistance RθJA = 100°C/W. At 25°C ambient and 1A on-state current, junction temperature rise is ~350°C - so actual operation requires derating or heatsinking. Maximum continuous ambient temperature depends on PCB copper area and airflow; typical design limit is +85°C ambient with 1 oz copper pour.
Does TB3500H-13-F require a series current-limiting resistor?
No external resistor is required for surge clamping, as the device latches and holds until current falls below its 150–800mA holding threshold. However, a series impedance may be needed upstream to limit follow current in AC line applications - especially where short-circuit current exceeds 50A ITSM rating.
How does TB3500H-13-F differ from standard TVS diodes?
Unlike unidirectional or bidirectional TVS diodes, TB3500H-13-F is a thyristor-based TSPD with crowbar action: it switches to low-impedance state once triggered and remains latched until current drops below IH. This provides lower clamping voltage under high-current surges but requires controlled follow current to ensure reset.
Is TB3500H-13-F compatible with lead-free reflow soldering?
Yes - it features matte tin-plated terminals rated for lead-free reflow per JEDEC J-STD-020, with moisture sensitivity level 1 (unlimited floor life at ≤30°C/60% RH). Peak reflow temperature must not exceed 260°C for ≤10 seconds, consistent with standard Pb-free profile.
