Product details
Overview
TS30111-M050QFNR 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), 27.5–28V clamping voltage at 40A, and 20mΩ dynamic resistance. It protects USB PD, USB Type-C VBus, and load switch inputs in industrial and portable electronics.
For engineers reviewing the TS30111-M050QFNR datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, clamping stability across temperature, and real-world use cases in USB Type-C and load switch protection circuits.
Technical Context
The TS30111-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 peak pulse current due to decreasing RDS(on).
It operates over –40°C to +125°C with stable clamping performance, 175pF junction capacitance at 22V/1MHz, and <600nA reverse leakage at VRWM. The device is optimized for unsymmetrical line protection and meets IEC 61000-4-4 (±4kV EFT) and IEC 61000-4-5 (±1kV, RS = 42Ω) standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC bus voltage it can protect without leakage or degradation |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures protected ICs (e.g., USB PD controllers) remain below damage threshold during surge |
| Peak Pulse Current | 40A (8/20μs) - supports industrial surge immunity per IEC 61000-4-5 Level 3/4 |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - eliminates need for secondary ESD stages in front-end interfaces |
| Dynamic Resistance | 20mΩ - enables low-voltage-drop shunting, minimizing energy dissipation in silicon and thermal stress |
| Junction Capacitance | 175pF at 22V/1MHz - compatible with 20V USB PD bus lines without signal integrity impact |

Pinout & Package
TS30111-M050QFNR is housed in a RoHS-compliant, halogen-free DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad not required (energy dissipated in FET channel). All six terminals are electrically functional: three parallel input pins and three parallel ground pins for low-inductance surge conduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected to minimize inductance and maximize 40A capability |
| Pins 4, 5, 6 | IN | Parallel-connected input terminals tied to protected bus (e.g., USB VBus); equal current sharing ensures uniform thermal loading |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage stays within 27.5–28V from 24A to 40A-enables predictable protection margin vs. TVS diodes whose VC rises linearly with IPP |
| Temperature-stable clamping | No increase in VC from –40°C to +125°C-eliminates derating calculations for high-temp industrial deployments |
| Low dynamic resistance | 20mΩ measured between 1A–40A-reduces I²R heating and improves reliability under repeated surges |
| High-energy ESD rating | ±30kV contact/air per IEC 61000-4-2-meets stringent end-equipment ESD compliance without external shielding |
| DFN-6 footprint | 1.6mm × 1.6mm area-saves >50% board space versus SO-8 or SOT-23 TVS alternatives while maintaining 40A rating |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |

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 code T22-confirmed as direct form-fit-function replacement per Semtech documentation | Same USB PD, load switch, and industrial bus use cases; validated in Semtech reference designs (Fig. 4 & 5) | Select TS30111-M050QFNR for Aetrix-sourced traceability and volume pricing; TDS2211P remains valid for legacy procurement |
| SMAJ22A | Standard unidirectional TVS diode; 35.1V clamping at 24A (vs. 27.5V), 1.5Ω RDYN (vs. 20mΩ), 125°C max TJ (vs. 150°C) | Limited to lower-energy applications; clamping rises to >40V at 125°C-unsuitable for USB PD or high-temp industrial use | Only consider SMAJ22A if cost is primary constraint and thermal derating and clamping margin are acceptable trade-offs |
Compared with TDS2211P, TS30111-M050QFNR offers identical protection performance with enhanced supply chain control; versus SMAJ22A, it delivers 12V lower clamping at full surge current and stable performance across temperature-critical for USB PD and industrial reliability.

FAQ
What is the clamping voltage of TS30111-M050QFNR at 40A surge current?
The TS30111-M050QFNR clamps at 27.5–28V under 40A peak pulse current (8/20μs waveform, 2Ω source impedance), as specified in its electrical characteristics table. This value remains stable across –40°C to +125°C, distinguishing it from standard TVS diodes whose clamping voltage increases with both current and temperature. The consistent 27.5–28V clamping ensures protected downstream ICs like USB PD controllers stay well below their absolute maximum ratings.
Does TS30111-M050QFNR require a thermal pad on the PCB?
No, TS30111-M050QFNR does not require a thermal pad. Its DFN-6 package dissipates surge energy through the low RDS(on) FET channel rather than junction heating, and Semtech explicitly states "no thermal pad is needed" in the datasheet. Instead, robust grounding via all three GND pins (1, 2, 3) and short, wide traces to the ground plane are essential to minimize parasitic inductance and ensure full 40A surge capability.
Can TS30111-M050QFNR protect bidirectional data lines like USB DP/DM?
No, TS30111-M050QFNR is designed exclusively for unidirectional 22V power or I/O line protection-not high-speed data lines. Its 175pF junction capacitance would severely degrade signal integrity on SuperSpeed USB lanes. For DP/DM protection, Semtech recommends low-capacitance TVS devices like RClamp3371ZC (<0.25pF); TS30111-M050QFNR is intended only for VBus, CC, or load switch input rails.
What is the maximum operating temperature for TS30111-M050QFNR?
The TS30111-M050QFNR has a specified operating temperature range of –40°C to +125°C, with junction temperature rated up to +150°C. Crucially, its clamping voltage remains stable across this entire range-unlike conventional TVS diodes, which exhibit rising VC with temperature. This makes TS30111-M050QFNR suitable for under-hood automotive modules, industrial motor drives, and sealed tablet enclosures where ambient temperatures exceed 85°C.
How does TS30111-M050QFNR differ from standard TVS diodes in surge response?
TS30111-M050QFNR uses a triggered FET architecture instead of a pn-junction, resulting in near-constant clamping voltage (27.5–28V) from 1A to 40A, whereas TVS diodes follow VC = VBR + IPP × RDYN-causing clamping to rise linearly with current. Its 20mΩ dynamic resistance also yields lower I²R losses and superior thermal behavior. These differences make TS30111-M050QFNR more reliable for high-energy, high-temperature applications like USB PD and industrial power inputs.
