Product details
Overview
TS30011-M018QFNR 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 protects USB PD, USB Type-C VBus, and load switch inputs in industrial and portable electronics.
For engineers reviewing the TS30011-M018QFNR datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, DFN-6 package layout guidance, functional role in surge-shunt architecture, and real-world implementation constraints for USB Type-C and industrial bus protection.
Technical Context
The TS30011-M018QFNR implements a precision-triggered shunt FET architecture - not a conventional TVS diode - enabling near-constant clamping voltage (27.5–28V) over 24–40A IPP and −40°C to +125°C. Its dynamic resistance is 20mΩ, achieved via low RDS(on) FET conduction activated only during transients.
It operates with reverse stand-off voltage (VRWM) of 22V, breakdown voltage (VBR) of 25–27.9V, and junction capacitance of 175pF at 22V/1MHz - optimized for DC power rail and high-voltage data line protection where low leakage (<600nA) and thermal stability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC operating voltage on protected line without leakage or conduction. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures downstream ICs (e.g., USB PD controllers) remain below damage threshold during worst-case surges. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements with 2Ω source impedance. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD robustness standards without derating. |
| Junction Capacitance | 175pF at 22V/1MHz - low enough for 22V power rail protection; not suitable for high-speed signal lines (e.g., USB SS). |
| Dynamic Resistance | 20mΩ - enables flat clamping curve by minimizing ΔV = I × RDYN rise across full 1–40A surge range. |
| Operating Temp | −40°C to +125°C - maintains specified clamping and leakage performance across extended industrial temperature range. |
Pinout & Package
TS30011-M018QFNR is housed in a Pb-free, RoHS-compliant DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with UL 94V-0 molding compound. All six terminals must be connected per layout guidelines to achieve rated 40A surge capability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; requires low-inductance connection to PCB ground plane via multiple vias. |
| Pins 4, 5, 6 | IN | Protected input node - connects directly to VBus or power line; all three pins must be shorted externally to maximize current sharing and thermal dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based shunt architecture | Enables constant clamping voltage independent of surge amplitude or ambient temperature - unlike TVS diodes whose VC rises linearly with IPP. |
| 20mΩ dynamic resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ESD), reducing risk of latch-up or gate oxide damage in downstream MOSFETs. |
| 175pF junction capacitance | Preserves power rail integrity without introducing resonant instability or excessive filtering - suitable for 22V DC bus protection only. |
| ±30kV ESD rating | Eliminates need for secondary ESD stages in front-end protection schemes for USB Type-C connectors and industrial I/O ports. |
| −40°C to +125°C operation | Supports deployment in uncontrolled environments such as outdoor IoT gateways, factory automation controllers, and automotive infotainment power supplies. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|

Use Value: Maintains 27.5–28V clamping at 40A and 125°C - 10V lower than typical TVS devices - preventing overvoltage damage to sensitive PD PHY and MCU logic. |
Use Scenario: Safeguarding input terminals of industrial-grade load switches (e.g., HS2950P) exposed to field wiring transients in remote meters and robotics. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage stress on internal FETs and OVP comparators during 1.2/50μs surge events. Use Value: Prevents premature failure of load switch ICs by holding clamping voltage below their absolute maximum VIN rating (typically 28–30V), even under sustained high-temp operation. |
| IoT Gateway DC Power Input Protection | Storage Device 22V Backup Rail Protection |
|
Use Scenario: Securing 22V auxiliary power inputs on cellular/NB-IoT gateways deployed in harsh electromagnetic environments. IC Role / Device Role / Timing Role: Single-component solution for combined IEC 61000-4-2, -4-4, and -4-5 compliance on primary DC input. Use Value: Reduces BOM count vs. multi-stage TVS+MOV designs while delivering superior thermal stability and smaller footprint (1.6×1.6mm). |
Use Scenario: Protecting 22V backup battery rails in enterprise SSDs and NAS enclosures against accidental hot-swap surges and ESD during maintenance. IC Role / Device Role / Timing Role: Low-leakage (≤600nA) protector preserving battery life while providing fail-safe clamping during unexpected voltage spikes. Use Value: Ensures uninterrupted operation during transient events without triggering false undervoltage lockout or draining backup capacitors. |
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; same Semtech TDS family - direct replacement with identical marking code T22XX. | No functional difference; used interchangeably in production for USB PD and industrial power rail protection. | Select when sourcing from alternate distributors or requiring documented legacy part number traceability. |
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.5V VC @ 12.3A; higher clamping, no temperature stability, 500W PPPK (vs. 1120W). | Limited to lower-energy surges; unsuitable for 40A/8/20μs or high-temp industrial use due to rising VC above 85°C. | Consider only for cost-sensitive, non-critical 22V lines where 35.5V clamping is acceptable and surge energy is <10A. |
Compared with TDS2211P and SMAJ22A, TS30011-M018QFNR delivers identical high-fidelity protection performance but with updated packaging and traceability - making it the preferred choice for new designs requiring full IEC 61000-4-5 Level 4 compliance and long-term supply continuity.

FAQ
What is the primary circuit function of TS30011-M018QFNR?
The TS30011-M018QFNR functions as a transient-diverting suppressor - using a precision-triggered shunt FET instead of a PN-junction TVS - to clamp high-energy surges on 22V power or I/O lines. Unlike standard TVS diodes, TS30011-M018QFNR maintains a nearly constant 27.5–28V clamping voltage across its full 40A surge rating and −40°C to +125°C operating range, making it ideal for USB PD and industrial bus protection where voltage margin is critical.
Does TS30011-M018QFNR require external bias or control signals?
No, TS30011-M018QFNR is a fully autonomous, passive protection device with no external control pins, enable inputs, or bias requirements. It operates solely on the voltage transient itself: when input voltage exceeds ~25V (breakdown threshold), its internal trigger circuit activates the shunt FET, diverting surge current to ground. This self-contained operation makes TS30011-M018QFNR simple to integrate into existing layouts without redesigning control logic or adding support components.
Can TS30011-M018QFNR be used on high-speed data lines like USB SuperSpeed?
No, TS30011-M018QFNR is not suitable for high-speed data lines. Its 175pF junction capacitance would severely degrade signal integrity on differential pairs operating above 100MHz (e.g., USB 3.x, PCIe, HDMI). TS30011-M018QFNR is explicitly designed for DC power rails and low-frequency I/O lines - such as USB Type-C VBus, load switch inputs, or 22V backup rails - where bandwidth is not a constraint and low clamping voltage is paramount.
How does TS30011-M018QFNR compare to traditional TVS diodes in thermal performance?
TS30011-M018QFNR exhibits superior thermal stability versus conventional TVS diodes: its clamping voltage remains flat from −40°C to +125°C, whereas TVS devices show significant VC increase with temperature due to rising dynamic resistance. This allows TS30011-M018QFNR to guarantee safe operation in sealed industrial enclosures or automotive under-hood environments where ambient temperatures exceed 85°C - a key reliability advantage confirmed in Semtech's characterization data for TS30011-M018QFNR.
What PCB layout practices are mandatory to achieve the rated 40A surge performance of TS30011-M018QFNR?
To achieve the full 40A (8/20μs) rating, TS30011-M018QFNR requires strict layout adherence: all three IN pins (4,5,6) must be shorted together with a low-inductance trace, and all three GND pins (1,2,3) must connect to a solid ground plane using ≥4 thermal vias. The device must be placed within 5mm of the protected connector, and no thermal pad is needed - energy is dissipated internally via the FET channel, not through package conduction. Deviations reduce effective surge handling below datasheet specifications.
