Product details
Overview
TS30011-M000QFNR from Semtech is a Transient Diverting Suppressor (TDS) designed for high-energy EOS protection of 22V-rated power or I/O lines. It delivers ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), and stable 27.5–28V clamping across its full current and temperature range (−40°C to +125°C), enabling robust USB PD and industrial load switch input protection.
For engineers reviewing the TS30011-M000QFNR datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DFN 1.6×1.6×0.55mm, 6-lead), confirmed clamping stability over temperature, dynamic resistance (20mΩ), junction capacitance (175pF), and validated alternative options for 22V EOS protection circuits.
Technical Context
The TS30011-M000QFNR 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 due to decreasing RDS(on) under surge, not fixed dynamic resistance.
It operates with reverse stand-off voltage (VRWM) of 22V, breakdown voltage (VBR) of 25–27.9V at 1mA, and clamps at 27.5–28V at both 24A and 40A (1.2/50μs + 8/20μs combination waveform, RS = 2Ω). Its low 20mΩ dynamic resistance and 175pF junction capacitance support high-speed, low-distortion protection in USB Type-C and industrial bus interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC operating voltage of protected line without leakage or conduction. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs) - 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 for 22V systems. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD immunity standards without degradation. |
| Dynamic Resistance | 20mΩ - enables flat clamping curve; minimizes voltage rise under increasing surge current, unlike TVS diodes. |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for USB PD VBUS protection without signal integrity impact on DC/low-frequency lines. |
Pinout & Package
TS30011-M000QFNR is housed in a RoHS-compliant DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no internal thermal pad required; energy dissipated in silicon). All six terminals must be connected for rated surge performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; all three pins must be connected to minimize inductance and maximize 40A capability. |
| Pins 4, 5, 6 | IN | Protected line input (e.g., USB PD VBUS, load switch VIN); parallel connection ensures uniform current sharing and optimal clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage stays within 27.5–28V from 24A to 40A and −40°C to +125°C - eliminates derating uncertainty in thermal design. |
| Surge-rated FET protection element | Replaces PN-junction TVS with low-RDS(on) shunt FET - avoids thermal runaway and enables higher IPP without junction-area scaling. |
| Low dynamic resistance | 20mΩ measured between 1A–40A (8/20μs) - reduces voltage overshoot during fast-rising transients compared to TVS diodes. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz) - protects against repetitive burst noise in industrial motor drives and PLCs. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |

Use Value: Delivers 40A surge handling in 1.6mm² footprint - replaces larger SO-8 TVS arrays while maintaining system-level surge compliance. |
Use Scenario: Securing main 22V input rails in ultrabooks and 2-in-1 tablets with USB-C charging and high-power peripherals. IC Role / Device Role / Timing Role: Secondary overvoltage clamp after front-end fuse, ensuring system survival during hot-plug events and cable coupling transients. Use Value: 175pF capacitance avoids interference with power sequencing or PMIC feedback loops - unlike higher-capacitance TVS solutions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Same die, identical electrical specs and package; TS30011-M000QFNR is Semtech's alternate marking for TDS2211P per official ordering documentation. | No functional difference - direct form-fit-function match for all USB PD, industrial, and computing applications. | Select TS30011-M000QFNR when sourcing via Aetrix Electronics' channel; identical qualification and traceability to TDS2211P. |
| uClamp2411ZA | 24V working voltage, lower 24A IPP rating, ±30kV ESD, but uses standard TVS architecture - clamping rises with current/temperature (≈32V at 24A, 125°C). | Suitable only for CC/SBU lines or lower-energy 24V rails; insufficient for 40A surge or stable clamping in high-temp environments. | Choose uClamp2411ZA only for secondary protection or non-critical 24V signals where cost is prioritized over clamping stability. |
Compared with TDS2211P and uClamp2411ZA, TS30011-M000QFNR offers identical performance to TDS2211P - including constant 27.5–28V clamping and 40A surge rating - while uClamp2411ZA requires thermal derating and exhibits higher, variable clamping unsuitable for primary 22V rail protection.

FAQ
What is the exact package type and dimensions of TS30011-M000QFNR?
TS30011-M000QFNR uses a 6-lead DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed pad. Pin 1 is marked by a laser dot; pins 1–3 are GND, pins 4–6 are IN. The land pattern follows Semtech's recommended layout with multiple vias to ground for minimal inductance - critical to achieving full 40A surge rating.
How does TS30011-M000QFNR differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with peak pulse current (VC = VBR + IPP × RDYN), TS30011-M000QFNR maintains 27.5–28V clamping from 24A to 40A and across −40°C to +125°C. This results from its surge-rated FET architecture and precision trigger circuit - eliminating thermal derating concerns present in PN-junction TVS devices.
Is TS30011-M000QFNR suitable for protecting USB PD VBUS lines up to 20V?
Yes - TS30011-M000QFNR is explicitly validated for USB PD VBUS protection in Semtech's application notes. With 22V working voltage, ±30kV ESD rating, and stable 28V clamping, it keeps voltage below the 30–33V damage threshold of common PD controllers (e.g., STUSB4500, CYPD3171) even under worst-case 40A surges at 125°C.
What is the junction capacitance of TS30011-M000QFNR, and why does it matter?
TS30011-M000QFNR has a junction capacitance of 175pF at 22V and 1MHz. This value is low enough to avoid distorting DC or low-frequency power rail monitoring while remaining compatible with USB PD power path designs. It is significantly lower than many 22V TVS arrays (>500pF), preventing false OVP triggering or regulator instability.
Does TS30011-M000QFNR require a thermal pad or heatsink on the PCB?
No - TS30011-M000QFNR dissipates surge energy in the silicon FET, not at a thermal junction. Semtech's datasheet explicitly states "no thermal pad is needed." Board layout focuses instead on low-inductance GND connections (all pins 1–3 tied to solid ground plane via multiple vias) and short, direct traces from connector to pins 4–6.
