Product details
Overview
TS30111-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 protects USB PD, USB Type-C VBus, and load switch inputs in industrial and portable electronics.
For engineers reviewing the TS30111-M000QFNR datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under 40A surge, DFN-6 thermal and layout performance, dynamic resistance ≤20mΩ, and compatibility with 22V bus protection in USB Type-C and industrial power rail designs.
Technical Context
The TS30111-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-27.5–28V-across 24A to 40A peak pulse current and −40°C to +125°C operating temperature.
Its architecture delivers <20mΩ dynamic resistance and 175pF junction capacitance at 22V reverse bias, enabling low-voltage overshoot suppression without signal distortion. The device operates with 130–600nA leakage at VRWM = 22V and maintains 25–27.9V breakdown voltage at 1mA test current.
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 + 1.2/50μs combo wave) - ensures protected ICs see sub-28V stress during worst-case surges |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment interfaces |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD requirements for connector-facing protection |
| Dynamic Resistance | ≤20mΩ - enables flat clamping curve and minimizes voltage rise under increasing surge current |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for 22V power rail protection without affecting load switch response or PD controller timing |
| Operating Temp | −40°C to +125°C - supports operation in harsh environments including industrial control cabinets and automotive under-hood modules |
Pinout & Package
TS30111-M000QFNR is housed in a RoHS-compliant DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no solder mask defined). All six terminals are surface-mount; pins 1–3 are internally connected GND, pins 4–6 are internally connected IN - requiring direct, low-inductance routing to protected line and ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current; all three must be vias-connected to internal ground plane for full 40A rating |
| 4, 5, 6 | IN | Protected input node - connects directly to 22V bus (e.g., USB PD VBus); all three pins must be shorted externally for rated performance |
Key Features
| Feature | Design Value |
|---|---|
| FET-based shunt architecture | Replaces traditional TVS with active clamping - eliminates linear VC = VBR + IPP×RDYN dependency and enables flat clamping |
| Temperature-stable clamping | 27.5–28V clamping maintained from −40°C to +125°C - avoids derating or overdesign for thermal margin |
| Low dynamic resistance | ≤20mΩ measured between 1A–40A - reduces voltage overshoot during fast-rising transients (e.g., ESD) |
| High-energy surge handling | 1120W peak pulse power (8/20μs) - sustains multiple 40A surges without parametric shift or failure |
| Ultra-low leakage | 130–600nA at 22V - prevents battery drain in always-on IoT and portable applications |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V VBus lines in USB-C receptacles against lightning-induced surges and hot-plug ESD events. IC Role / Device Role / Timing Role: Primary EOS suppressor placed adjacent to Type-C connector, clamping transients before they reach PD controller or buck converter. Use Value: Maintains 27.5–28V clamping at 40A and 125°C - avoids overvoltage damage to 24V-tolerant PD controllers where standard TVS would exceed 35V. |
Use Scenario: Safeguarding input pins of high-side load switches (e.g., HS2950P) in remote meters and robotics against 1kV/42Ω surges per IEC 61000-4-5. IC Role / Device Role / Timing Role: Front-end transient shunt that limits voltage seen by load switch FET gate oxide and internal OVP circuitry. Use Value: Prevents latch-up or gate rupture in load switches by holding clamping below 28V - well under typical 30V absolute max ratings. |
| IoT Edge Node Power Rail Protection | Industrial Equipment DC Bus Protection |
Use Scenario: Securing 22V auxiliary rails in battery-powered gateways and sensor hubs exposed to field ESD and induced surges. IC Role / Device Role / Timing Role: Standalone EOS protector on main power input, co-located with input capacitor and fuse. Use Value: 130–600nA leakage preserves battery life; 1.6×1.6mm footprint saves >60% board area vs. SOT-23 TVS alternatives. |
Use Scenario: Hardening 22V control bus in PLC I/O modules and motor drives against coupling from nearby AC mains or relay switching. IC Role / Device Role / Timing Role: Point-of-entry suppressor on backplane or terminal block feed, upstream of LDOs and microcontrollers. Use Value: Stable 27.5–28V clamping across −40°C to +125°C ensures consistent protection in uncontrolled ambient environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P.C | Identical electrical specs, same DFN-6 package, identical marking code T22; differs only in tape-and-reel packaging (3,000 pcs/reel vs. TS30111-M000QFNR's unspecified quantity). | Same USB PD, load switch, and industrial bus use cases; no functional or layout change required. | Select TDS2211P.C for standard volume procurement with known reel count; TS30111-M000QFNR may reflect custom packaging or distribution channel variant. |
| SMAJ22A | Standard unidirectional TVS diode; 22V standoff, 35.5V min clamping at 14.3A (8/20μs), 1.5Ω dynamic resistance - clamping rises sharply with current and temperature. | Suitable only for lower-energy surges (<15A) or ambient-temperature-limited designs; cannot replace TS30111-M000QFNR in 40A/125°C applications. | Use SMAJ22A only where cost is critical and surge energy is low; avoid where flat clamping or high-temp reliability is required. |
Compared with TDS2211P.C, TS30111-M000QFNR offers identical protection performance but may differ in logistics handling; compared with SMAJ22A, TS30111-M000QFNR delivers 40A capability, 20mΩ dynamic resistance, and temperature-invariant clamping - enabling robust 22V rail protection where legacy TVS falls short.

FAQ
What is the exact clamping voltage specification for TS30111-M000QFNR at 40A surge current?
The TS30111-M000QFNR clamps at 27.6–28V under 40A peak pulse current using the IEC 61000-4-5 combination waveform (1.2/50μs voltage + 8/20μs current, RS = 2Ω). This value is guaranteed across −40°C to +125°C and reflects its FET-based architecture - not a fixed VBR + IPP×RDYN sum like conventional TVS devices. TS30111-M000QFNR maintains this tight window due to ultra-low dynamic resistance.
Is TS30111-M000QFNR pin-compatible with TDS2211P.C?
Yes, TS30111-M000QFNR and TDS2211P.C share identical DFN-6 package dimensions (1.6mm × 1.6mm × 0.55mm), pin configuration (pins 1–3 = GND, pins 4–6 = IN), and electrical specifications. They differ only in packaging logistics - TDS2211P.C is specified for 3,000-unit tape-and-reel delivery, while TS30111-M000QFNR may reflect alternate distribution formatting. No PCB or schematic changes are needed when substituting TS30111-M000QFNR for TDS2211P.C.
Can TS30111-M000QFNR protect USB Type-C CC lines?
No, TS30111-M000QFNR is not suitable for USB Type-C CC (Configuration Channel) line protection. Its 22V working voltage and 6-pin DFN layout are optimized for high-current power rail (VBus) or load switch input protection - not low-capacitance, bidirectional data lines. For CC lines, Semtech recommends uClamp2411ZA (24V, 0.5pF), which provides appropriate voltage rating and sub-0.6pF capacitance to avoid signal integrity issues. TS30111-M000QFNR's 175pF junction capacitance would disrupt CC signaling.
What is the maximum junction temperature rating for TS30111-M000QFNR?
The TS30111-M000QFNR has a maximum junction and storage temperature rating of +150°C, with an operating temperature range of −40°C to +125°C. Its clamping voltage remains stable across this full range - unlike standard TVS diodes whose VC increases with temperature. This makes TS30111-M000QFNR suitable for enclosed industrial enclosures or automotive under-dash locations where ambient temperatures approach 105°C and self-heating must be accounted for.
Does TS30111-M000QFNR require a thermal pad or special PCB copper pour?
No, TS30111-M000QFNR does not require a thermal pad or dedicated copper pour. Its DFN-6 package dissipates surge energy through conduction via pins 1–3 (GND) and pins 4–6 (IN), and the datasheet explicitly states "no thermal pad is needed" under transient conditions. Instead, design focus should be on low-inductance grounding: connect all three GND pins with multiple vias to an internal ground plane, and route the IN net as a short, wide trace directly from connector to device - minimizing parasitic inductance that could elevate clamping voltage during fast ESD events. TS30111-M000QFNR relies on package-level conduction, not board-level thermal mass.
