Product details
Overview
TS30042-M050QFNR from Semtech is a transient diverting suppressor 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), 27.5–28V clamping voltage at 40A, 20mΩ dynamic resistance, and 175pF junction capacitance. It protects USB PD, USB Type-C VBus, and load switch inputs in industrial and portable electronics.
For engineers reviewing the TS30042-M050QFNR datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature and current, low dynamic resistance for flat VC vs. IPP response, DFN-6 package layout compatibility, and compliance with IEC 61000-4-2/4-4/4-5 surge standards.
Technical Context
The TS30042-M050QFNR uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that turns on the shunt path when transient voltage exceeds breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly constant-27.5–28V-from 24A to 40A and across −40°C to +125°C due to decreasing RDS(on) under surge.
It operates with a 22V reverse stand-off voltage (VRWM) and 25–27.9V breakdown (VBR), delivering 1120W peak pulse power. Its 175pF capacitance at 22V/1MHz and 130–600nA leakage support high-speed bus protection without signal integrity degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC operating voltage on protected line |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures downstream ICs (e.g., USB PD controllers) remain below damage threshold |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds Level 4 for robust system-level ESD robustness |
| Dynamic Resistance | 20mΩ - enables flat clamping response and minimizes voltage rise under increasing surge current |
| Junction Capacitance | 175pF at 22V/1MHz - compatible with USB PD VBus (DC-coupled) without compromising surge margin |
Pinout & Package
TS30042-M050QFNR is housed in a RoHS-compliant DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad not required; all six terminals are surface-mount, lead-free, and UL 94V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected to maximize current handling and minimize inductance |
| 4, 5, 6 | IN | Protected line input (e.g., VBus); parallel connection ensures uniform current sharing and optimal 40A capability |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping voltage | 27.5–28V across full 24–40A range and −40°C to +125°C - eliminates derating for temperature or current |
| FET-based shunt architecture | Replaces pn-junction TVS with low-RDS(on) MOSFET - reduces clamping dependency on dynamic resistance |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz) - protects against repetitive fast transients in noisy industrial environments |
| Low leakage | 130–600nA at 22V - prevents excessive quiescent power loss in always-on battery-powered IoT devices |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting the 20V–22V VBus line in USB Type-C ports supporting Power Delivery up to 100W. IC Role / Device Role / Timing Role: Transient diverting suppressor placed between connector and PD controller or load switch. Use Value: Maintains clamping at ≤28V across temperature and surge current, preventing overvoltage damage to sensitive PD controllers during lightning or ESD events. | Use Scenario: Safeguarding the input of industrial-grade load switches (e.g., HS2950P) in remote meters, robotics, and factory automation systems. IC Role / Device Role / Timing Role: Primary EOS protection device absorbing 40A surges before they reach the load switch's internal FET. Use Value: Keeps clamping voltage below the load switch's absolute maximum rating, extending reliability in ungrounded or long-cable field deployments. |
| IoT Device Power Rail Protection | Notebook/Tablet VBus Line Protection |
Use Scenario: Securing 22V-capable power rails in battery-backed smart sensors and edge gateways exposed to user-handled connectors. IC Role / Device Role / Timing Role: Standalone EOS protector on main DC input rail, co-located near the connector. Use Value: Delivers ±30kV ESD immunity and stable clamping without requiring additional series impedance or filtering components. | Use Scenario: Protecting the VBus line in ultraportable notebooks and tablets where space and thermal constraints limit TVS options. IC Role / Device Role / Timing Role: Compact DFN-6 transient suppressor mounted directly at USB-C receptacle. Use Value: 1.6mm × 1.6mm footprint saves board area versus SOD-323 or SMA packages while maintaining 40A surge rating. |
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, same DFN-6 package, identical marking and reel packaging - direct form-fit-function match | Same use cases: USB PD, load switch, industrial VBus | Select TS30042-M050QFNR when sourcing from Aetrix Electronics' certified channel with traceable lot history |
| uClamp2411ZA | 24V working voltage, lower 24A surge rating, higher 33V clamping, smaller 0.65mm × 0.65mm DFN-2 package | Better suited for CC/SBU lines than VBus; insufficient for 40A industrial surges | Choose only for auxiliary signal-line protection where size trumps surge capacity |
Compared with TDS2211P, TS30042-M050QFNR offers identical performance and drop-in compatibility, while uClamp2411ZA trades surge robustness for ultra-small size-making it unsuitable as a VBus replacement but viable for secondary signal lines.

FAQ
What is the clamping voltage of TS30042-M050QFNR at 40A surge current?
The TS30042-M050QFNR clamps at 27.5–28V under 40A peak pulse current (8/20μs waveform). This value is guaranteed across −40°C to +125°C and reflects its FET-based architecture, which maintains near-constant voltage via decreasing RDS(on), unlike conventional TVS diodes whose clamping rises linearly with current.
Is TS30042-M050QFNR pin-compatible with TDS2211P?
Yes, TS30042-M050QFNR is pin-compatible with TDS2211P: both use identical 6-pin DFN (1.6mm × 1.6mm) packages with pins 1–3 as GND and pins 4–6 as IN. Layout, solder stencil, and PCB footprint are interchangeable, enabling seamless substitution without redesign.
Does TS30042-M050QFNR require a thermal pad on the PCB?
No, TS30042-M050QFNR does not require a thermal pad. Its energy dissipation occurs within the silicon die during transient events, and the datasheet explicitly states no thermal pad is needed. Proper grounding via all three GND pins and short, low-inductance traces to the ground plane suffices for reliable operation.
Can TS30042-M050QFNR protect USB SuperSpeed differential pairs?
No, TS30042-M050QFNR is not intended for USB SuperSpeed (TX/RX) lines. Its 175pF junction capacitance would severely degrade high-speed signal integrity. It is designed exclusively for DC-coupled power lines like VBus. For SuperSpeed protection, Semtech recommends low-capacitance devices such as RClamp3371ZC (<0.25pF).
What is the maximum operating temperature range for TS30042-M050QFNR?
The TS30042-M050QFNR operates from −40°C to +125°C ambient temperature. Its clamping voltage remains stable across this full range, and its junction temperature can reach +150°C, making it suitable for under-hood automotive accessories, industrial controls, and thermally constrained portable electronics.
