Product details
Overview
TS30011-M033QFNR 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 uses a surge-rated FET with <20mΩ dynamic resistance to maintain near-constant clamping voltage in USB PD, load switch input, and industrial bus protection.
For engineers reviewing the TS30011-M033QFNR datasheet, pinout, applications, or equivalent options, key selection criteria include its 22V working voltage, DFN 1.6×1.6mm 6-lead package, low 175pF junction capacitance, ±4kV IEC 61000-4-4 EFT rating, and constant-clamp behavior under 40A transients - critical for robust USB Type-C, IoT, and industrial equipment designs.
Technical Context
The TS30011-M033QFNR implements a precision-triggered shunt-FET architecture: a dedicated trigger circuit senses overvoltage events and activates a low-RDS(on) FET to divert surge current to ground. Unlike conventional TVS diodes, its clamping voltage remains nearly flat (27.5–28V) from 24A to 40A and across −40°C to +125°C due to decreasing FET on-resistance under higher current.
This architecture delivers superior thermal stability and energy handling versus standard TVS devices - enabling reliable protection where voltage margin is tight (e.g., USB PD controllers rated ≤28V) and ambient temperatures exceed 85°C. Its 1.6mm × 1.6mm DFN package integrates three parallel input terminals (Pins 4–6) and three ground terminals (Pins 1–3) to minimize parasitic inductance and maximize surge current sharing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD bus and industrial 24V rail systems without derating. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave) - stays below typical 28V damage threshold of USB PD controllers. |
| 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 USB IF and industrial ESD requirements. |
| Junction Capacitance | 175pF @ 22V, 1MHz - low enough for 22V power-line protection without signal integrity impact. |
| Dynamic Resistance | 20mΩ - enables flat clamping by reducing VC = IPP × RDYN contribution. |
| EFT Immunity | ±4kV (5/50ns, 5kHz & 100kHz, IEC 61000-4-4) - protects against burst noise in motor drives and PLCs. |
Pinout & Package
TS30011-M033QFNR is housed in a RoHS-compliant, halogen-free DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no solder mask defined). The 6-lead layout supports high-current surge handling via parallel terminal grouping and requires all pins to be connected for full 40A rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path - all three must be connected to minimize inductance and enable full 40A surge dissipation. |
| Pins 4, 5, 6 | IN | Protected line input - parallel connection ensures uniform current sharing and reduces trace impedance to protected IC. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based clamping | Replaces PN-junction TVS with active shunt switch - eliminates linear VC rise vs. IPP, enabling tighter voltage margins. |
| Constant clamping across temperature | 27.5–28V clamping maintained from −40°C to +125°C - eliminates thermal derating calculations for industrial deployments. |
| Low dynamic resistance | 20mΩ measured between 1A–40A - ensures minimal voltage overshoot during fast-rising surges (e.g., ESD). |
| High-energy surge rating | 1120W peak pulse power (8/20μs) - supports repeated lightning-induced transients in remote meters and outdoor IoT nodes. |
| Ultra-low leakage | ≤600nA @ 22V - prevents measurable power loss in always-on battery-backed industrial sensors. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting VBus lines in USB Type-C ports supporting up to 20V/5A PD negotiation, exposed to ESD and system-level surges. IC Role / Device Role / Timing Role: Primary high-energy shunt protector placed directly at connector, clamping transients before they reach PD controller and power switches. Use Value: Maintains 27.5–28V clamping at 40A and 125°C - avoids overvoltage damage to 28V-rated PD controllers where conventional TVS would exceed 35V. |
Use Scenario: Safeguarding input terminals of industrial-grade load switches (e.g., HS2950P) in remote metering, robotics, and factory automation systems. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage seen by internal FET gate oxide and overvoltage protection circuitry. Use Value: Prevents latch-up or permanent gate oxide breakdown in load switches by holding clamping voltage below 28V even during 40A 8/20μs surges at elevated ambient temperatures. |
| IoT Edge Node Power Bus Protection | Industrial Equipment DC Power Input |
|
Use Scenario: Securing 22V-rated power rails in battery-powered or PoE-powered IoT edge nodes deployed in electrically noisy environments (e.g., smart building gateways). IC Role / Device Role / Timing Role: Single-device solution for combined ESD, EFT, and surge protection on main power input, eliminating multi-stage TVS+MOV designs. Use Value: Delivers ±30kV ESD, ±4kV EFT, and 40A surge capability in 2.56mm² footprint - reduces BOM count and PCB area vs. discrete TVS+capacitor solutions. |
Use Scenario: Protecting 24V DC inputs of programmable logic controllers (PLCs), motor drives, and HMI panels subject to inductive switching transients and lightning-induced surges. IC Role / Device Role / Timing Role: Robust front-end suppressor compliant with IEC 61000-4-5 Level 4 (±1kV, 42Ω source), placed before bulk capacitance and input filters. Use Value: Enables single-component compliance with industrial surge immunity standards while maintaining <28V clamping - simplifies design validation and reduces failure-in-field risk. |
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-M033QFNR is Semtech's alternate marking for TDS2211P per official ordering documentation. | Direct functional and mechanical replacement - validated for same USB PD, load switch, and industrial use cases. | Select TS30011-M033QFNR when sourcing from Aetrix Electronics; identical performance and qualification to TDS2211P. |
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.5V VC @ 22.5A; no constant-clamp behavior; VC rises with temperature and current. | Limited to lower-energy applications; unsuitable where clamping must stay ≤28V at 40A or >85°C ambient. | Use only if cost sensitivity outweighs clamping stability requirements and surge rating is capped at ≤22.5A. |
Compared with TDS2211P (identical part) and SMAJ22A (conventional TVS), TS30011-M033QFNR delivers flat 27.5–28V clamping across full 40A/−40°C–125°C range - enabling robust protection in USB PD and industrial systems where SMAJ22A's rising VC risks controller damage.

FAQ
What is the working voltage rating of TS30011-M033QFNR?
The TS30011-M033QFNR has a reverse stand-off voltage (VRWM) of 22V, meaning it reliably blocks up to 22V DC or continuous operating voltage on protected lines without leakage or conduction. This makes TS30011-M033QFNR ideal for 22V-rated USB PD buses and industrial 24V systems with appropriate margin.
How does TS30011-M033QFNR achieve constant clamping voltage across varying surge currents?
TS30011-M033QFNR uses a precision-triggered surge-rated FET instead of a PN junction. As peak pulse current increases from 24A to 40A, the FET's RDS(on) decreases, counteracting the I×R voltage drop - resulting in stable 27.5–28V clamping. This behavior is confirmed in the datasheet's clamping vs. IPP curves and distinguishes TS30011-M033QFNR from conventional TVS diodes.
Is TS30011-M033QFNR pin-compatible with TDS2211P?
Yes - TS30011-M033QFNR is Semtech's alternate part number for TDS2211P, sharing identical die, electrical specifications, DFN 1.6×1.6mm 6-lead package, pinout (Pins 1–3 = GND, Pins 4–6 = IN), and thermal characteristics. No PCB or schematic changes are required when substituting TS30011-M033QFNR for TDS2211P.
What is the maximum junction temperature and operating ambient range for TS30011-M033QFNR?
TS30011-M033QFNR supports a junction and storage temperature range of −55°C to +150°C, with a specified operating ambient temperature range of −40°C to +125°C. Its clamping voltage remains stable across this full range - a key advantage over TVS diodes whose VC degrades significantly above 85°C.
Can TS30011-M033QFNR be used to protect high-speed data lines like USB SuperSpeed or PCIe?
No - TS30011-M033QFNR is designed for power-line and low-speed I/O protection (e.g., VBus, CC, SBU, load switch inputs), not high-speed signal lines. Its 175pF junction capacitance would severely degrade signal integrity on >100MHz links. For USB SS/DP/DM lines, Semtech recommends low-capacitance TVS devices such as RClamp3371ZC (<0.25pF), not TS30011-M033QFNR.
