Product details
Overview
TS30042Q-M000QFNR from Semtech is a Transient Diverting Suppressor (TDS) designed for high-energy EOS protection of 22V-rated power or I/O lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), and stable 27.5–28V clamping across temperature and current range. It uses a surge-rated FET with precision trigger circuitry to maintain near-constant clamping voltage - unlike conventional TVS diodes - and is deployed in USB Type-C PD input protection and industrial load switch front-end circuits.
For engineers reviewing the TS30042Q-M000QFNR datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability under 40A transients, DFN-6 thermal and layout performance, 175pF junction capacitance at 22V, and compatibility with 22V bus systems requiring robust ±1kV IEC 61000-4-5 surge immunity.
Technical Context
The TS30042Q-M000QFNR implements a voltage-triggered shunt architecture using a low-RDS(on) surge FET activated by an integrated precision reference and drive circuit. Its clamping voltage remains nearly invariant from −40°C to +125°C and across 1A–40A transient currents due to dynamic reduction of FET on-resistance under surge conditions.
This architecture delivers 20mΩ dynamic resistance (measured 1A–40A, 8/20μs), enabling stable 27.5–28V clamping versus conventional TVS devices whose VC rises linearly with IPP. It supports unsymmetrical line protection per IEC 61000-4-5 with ±1kV (1.2/50μs, RS=42Ω) and meets IEC 61000-4-4 EFT immunity up to ±4kV.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC or RMS operating voltage on protected line without leakage degradation. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo waveform, RS=2Ω) - ensures downstream 24V-rated ICs (e.g., USB PD controllers) remain below damage threshold during surge. |
| Peak Pulse Current | 40A (8/20μs) - supports industrial ±1kV surge compliance (IEC 61000-4-5) with 42Ω source impedance. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds Level 4 requirements for rugged portable and industrial interfaces. |
| Junction Capacitance | 175pF at 22V, 1MHz - suitable for <20V bus protection where signal integrity is secondary to surge robustness (e.g., VBUS, load switch inputs). |
| Dynamic Resistance | 20mΩ - enables flat clamping curve; reduces voltage overshoot during fast-rising transients compared to TVS diodes with fixed RDYN. |
Pinout & Package
TS30042Q-M000QFNR is housed in a Pb-free, RoHS-compliant DFN package measuring 1.6mm × 1.6mm × 0.55mm with 6 leads and UL 94V-0 molding compound. All pins must be soldered for rated surge performance: three GND pins provide low-inductance return path; three IN pins parallel the protected line to minimize trace inductance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground terminals - must be connected to solid ground plane via multiple vias to minimize parasitic inductance during 40A surge discharge. |
| 4, 5, 6 | IN | Parallel-connected input terminals - connect directly to protected bus (e.g., USB PD VBUS); all three required to achieve full 40A rating and thermal derating margin. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V from −40°C to +125°C and 1A–40A - eliminates thermal derating uncertainty in industrial environments. |
| FET-based shunt protection | Surge energy dissipated in low-RDS(on) channel instead of PN junction - avoids thermal runaway and enables higher single-pulse energy handling than TVS diodes. |
| Low dynamic resistance | 20mΩ measured over full 1A–40A range - minimizes I×R voltage rise during fast transients, critical for protecting 24V logic interfaces. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz bursts) - ensures reliability in electrically noisy factory automation and motor control systems. |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Front-End Protection |

Use Scenario: Protecting 20V–22V USB PD VBUS lines against lightning-induced surges, connector hot-plug transients, and ESD events in notebooks, docking stations, and chargers. IC Role / Device Role / Timing Role: Primary shunt protector placed immediately after Type-C receptacle; clamps transients before they reach PD controller and buck-boost ICs. Use Value: Maintains 27.5–28V clamping at 40A and 125°C - prevents overvoltage damage to 24V-rated PD controllers where conventional TVS would exceed 38V at same conditions. |
Use Scenario: Safeguarding enable and input pins of industrial-grade load switches (e.g., HS2950P) in remote meters, robotics, and PLC I/O modules exposed to field wiring surges. IC Role / Device Role / Timing Role: Front-end transient suppressor on VIN rail; limits voltage seen by internal FET gate oxide and overvoltage protection circuitry. Use Value: Clamps to ≤28V during ±1kV IEC 61000-4-5 surges - keeps load switch drain-source voltage within safe SOA, avoiding latch-up or permanent failure. |
| IoT Device Power Bus Protection | Storage Device 22V Rail Protection |
|
Use Scenario: Securing 12–22V auxiliary power rails in battery-powered IoT gateways and edge sensors subjected to ESD during handling and EFT in factory settings. IC Role / Device Role / Timing Role: Single-device solution for combined ESD, EFT, and surge protection on main system rail - replaces multi-component TVS+MLV stacks. Use Value: Delivers ±30kV ESD, ±4kV EFT, and 40A surge in 1.6mm² footprint - reduces BOM count and PCB area vs. discrete TVS + capacitor solutions. |
Use Scenario: Protecting 22V intermediate bus in NVMe SSD enclosures and enterprise storage backplanes from hot-swap transients and board-level ESD. IC Role / Device Role / Timing Role: High-energy clamping device on primary power input - absorbs energy from connector arcing and backplane coupling events. Use Value: 1120W peak pulse power rating (8/20μs) handles repetitive surges without parameter drift - ensures long-term reliability in 24/7 data center operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Identical electrical specs, pinout, and package - direct manufacturer-recommended replacement for TS30042Q-M000QFNR; same Semtech TDS family, identical marking code T22. | Same use cases: USB PD, load switch, industrial 22V bus protection. | Select when sourcing from authorized Semtech channels or requiring full documentation traceability to Rev 2.5 datasheet. |
| uClamp2411ZA | 24V working voltage, lower 24A IPP rating, 0.25pF capacitance - optimized for CC/SBU lines, not power rails; lacks constant-clamp FET architecture. | Designed for low-capacitance data-line protection (CC, SBU), not high-current VBUS or load switch inputs. | Choose only for signal-line protection where <0.3pF is mandatory; not functionally substitutable for TS30042Q-M000QFNR's power-rail role. |
Compared with TDS2211P (identical spec and form) and uClamp2411ZA (lower IPP, signal-optimized), TS30042Q-M000QFNR delivers verified 40A surge handling and thermally stable clamping essential for 22V power rail protection - making it the sole suitable option for high-energy industrial and USB PD front-end applications.

FAQ
What is the maximum continuous operating voltage for TS30042Q-M000QFNR?
The TS30042Q-M000QFNR has a reverse stand-off voltage (VRWM) of 22V, meaning it can continuously withstand up to 22V DC or RMS on its IN pins without significant leakage. This makes TS30042Q-M000QFNR ideal for protecting 20V USB PD VBUS lines and 22V industrial power rails where sustained overvoltage must be avoided.
Does TS30042Q-M000QFNR require external components for basic surge protection?
No, TS30042Q-M000QFNR operates as a fully self-contained transient suppressor - no external capacitors, resistors, or bias networks are needed. Its integrated trigger circuit and shunt FET enable immediate response to EOS events. However, optimal PCB layout (short traces, multiple GND vias, placement near connector) is essential to achieve rated 40A performance.
How does TS30042Q-M000QFNR differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN), TS30042Q-M000QFNR uses a surge-rated FET that lowers RDS(on) under transient stress, resulting in near-constant 27.5–28V clamping from 1A to 40A and −40°C to +125°C - a key advantage for TS30042Q-M000QFNR in thermally variable environments.
Can TS30042Q-M000QFNR be used on high-speed data lines like USB SuperSpeed?
No - TS30042Q-M000QFNR has 175pF junction capacitance at 22V, which would severely degrade signal integrity on USB 3.x or PCIe lanes. It is intended exclusively for power or low-speed control lines (e.g., VBUS, load switch EN, CC lines with external low-C protection). For SuperSpeed lines, Semtech recommends RClamp3371ZC (<0.25pF), not TS30042Q-M000QFNR.
What is the recommended PCB layout for TS30042Q-M000QFNR to achieve full 40A rating?
To achieve the full 40A peak pulse current rating, all three IN pins (4,5,6) must connect via a single low-inductance trace to the protected line, and all three GND pins (1,2,3) must connect to a solid ground plane using ≥4 vias. TS30042Q-M000QFNR must be placed within 5mm of the connector - longer traces add inductance that increases clamping voltage during fast transients.
