Product details
Overview
TS30012-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 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 TS30012-M000QFNR datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability over temperature, low dynamic resistance for minimal voltage overshoot, DFN-6 package footprint compatibility, and compliance with IEC 61000-4-2/4-4/4-5 standards for robust system-level surge immunity.
Technical Context
The TS30012-M000QFNR implements an active shunt architecture: a precision trigger circuit detects overvoltage events and drives a low-RDS(on) FET into conduction, diverting transient current to ground. Unlike passive TVS diodes, its clamping voltage remains nearly constant-27.5–28V at 24A and 40A-due to decreasing FET on-resistance under surge conditions.
This architecture delivers superior thermal stability: clamping voltage varies less than 0.5V from −40°C to +125°C, and peak pulse current capability remains rated up to +125°C. The device operates with 175pF junction capacitance at 22V and exhibits only 130–600nA reverse leakage, enabling use on high-speed or low-leakage 22V bus lines without signal integrity compromise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC or RMS operating voltage on protected line without leakage or degradation |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures downstream 24V-rated ICs (e.g., USB PD controllers, load switches) remain below damage threshold during worst-case surge |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment and USB PD applications |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD requirements, eliminating need for secondary ESD stages |
| Dynamic Resistance | 20mΩ - enables flat clamping response and minimizes voltage overshoot during fast-rising transients |
| Junction Capacitance | 175pF at 22V, 1MHz - compatible with DC power rails and low-speed control lines; not suitable for >100MHz data paths |
| Package | DFN-6 (1.6 × 1.6 × 0.55 mm) - provides 60% board area reduction vs. SO-8 TVS solutions while supporting high-current PCB layout with triple-pin parallel routing |
Pinout & Package
TS30012-M000QFNR is housed in a RoHS-compliant, halogen-free DFN-6 package (1.6 mm × 1.6 mm × 0.55 mm) with exposed thermal pad not required-energy dissipation occurs within the silicon FET structure. All six terminals are surface-mount; no thermal pad or solder paste voiding concerns apply.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Parallel ground return path-must be connected together and to system ground with low-inductance vias to sustain 40A surge current |
| Pins 4, 5, 6 | IN | Parallel input connection to protected line-pins must be shorted externally to maximize current sharing and minimize trace inductance |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage deviates ≤0.5V across −40°C to +125°C and 1–40A surge range-enables reliable protection without derating |
| Surge-rated FET protection element | Replaces traditional pn-junction TVS; eliminates thermal runaway risk and enables higher IPP in same footprint |
| Triple-pin parallel I/O and GND | Reduces effective series inductance by ≥50% vs. single-pin configurations-critical for sub-10ns ESD rise time suppression |
| Low leakage & capacitance | 600nA max IR at 22V and 175pF CJ enable use on always-on 22V rails without standby power penalty or signal loading |
| UL 94V-0 molding compound | Ensures flame-retardant reliability in enclosed industrial and consumer enclosures without additional conformal coating |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |

IC Role / Device Role / Timing Role: Active shunt suppressor that triggers within nanoseconds to clamp surges before USB PD controller ICs experience overvoltage stress. Use Value: Maintains 27.5–28V clamping at full 40A surge and 125°C ambient-prevents false shutdown or latch-up in high-temperature docking stations. |
Use Scenario: Safeguarding input pins of high-side load switches (e.g., HS2950P) in remote meters and robotics against lightning-induced surges on 24V DC distribution lines. IC Role / Device Role / Timing Role: Primary front-end EOS protector that limits voltage seen by the load switch's internal FET gate oxide and drain-source junction. Use Value: Prevents catastrophic failure of the load switch by holding clamping voltage 3–4V below typical 30V FET breakdown, even at elevated temperatures. |
| IoT Edge Node Power Rail Protection | Industrial Equipment 24V Control Bus |
|
Use Scenario: Securing always-on 22V auxiliary rails powering cellular modems, sensors, and MCU peripherals in battery-backed IoT gateways deployed outdoors. IC Role / Device Role / Timing Role: Standalone transient suppressor placed at connector entry point to absorb ESD, EFT, and surge energy before it propagates to sensitive analog and RF sections. Use Value: Delivers ±30kV ESD immunity and ±4kV EFT immunity without degrading signal integrity-no added capacitance on critical sensor bias lines. |
Use Scenario: Hardening PLC I/O module backplane power inputs against induced surges from motor drive switching and relay coil flyback in factory automation systems. IC Role / Device Role / Timing Role: High-energy shunt device mounted directly at DIN-rail power entry to protect upstream DC-DC converters and downstream digital isolators. Use Value: Sustains 40A surge current without parameter shift-eliminates need for redundant TVS strings or oversized heatsinking in space-constrained modules. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A | Passive unidirectional TVS diode; 35.1V clamping at 12.4A (8/20μs); 1000W peak power; 200pF capacitance | Higher clamping voltage and strong temperature dependence-requires derating above 85°C; unsuitable for 24V-system margin-critical designs | Select when cost sensitivity outweighs clamping precision and thermal stability requirements; verify layout can handle higher voltage overshoot. |

FAQ
What is the maximum continuous operating voltage for TS30012-M000QFNR?
The TS30012-M000QFNR has a reverse stand-off voltage (VRWM) of 22V, meaning it supports continuous DC or RMS voltages up to 22V on the protected line without significant leakage or degradation. This rating aligns with USB PD 3.0 VBUS and industrial 24V nominal systems operating at reduced voltage margins.
How does TS30012-M000QFNR achieve stable clamping voltage across temperature?
TS30012-M000QFNR uses an active FET-based shunt architecture instead of a passive pn-junction. Its trigger circuit activates a low-RDS(on) FET whose on-resistance decreases under surge, counteracting thermal drift. As a result, clamping voltage stays within 27.5–28V from −40°C to +125°C-unlike TVS diodes whose VC rises linearly with temperature.
Can TS30012-M000QFNR be used on high-speed data lines like USB SuperSpeed?
No-TS30012-M000QFNR is not suitable for high-speed data lines. With 175pF junction capacitance at 22V, it would severely attenuate signals above ~100MHz. It is intended exclusively for DC power rails, control lines, or low-speed buses. For USB SS, DP/DM, or PCIe lanes, Semtech recommends RClamp3371ZC (<0.25pF).
What is the recommended PCB layout for optimal surge performance with TS30012-M000QFNR?
Place TS30012-M000QFNR as close as possible to the protected connector. Short all three IN pins (4,5,6) together with a wide, low-inductance trace; similarly tie all three GND pins (1,2,3) to a solid ground plane using ≥3 vias. Avoid thermal pads-energy is dissipated internally, and excessive copper under the device adds parasitic inductance.
Is TS30012-M000QFNR compliant with RoHS and halogen-free standards?
Yes-TS30012-M000QFNR is Pb-free, halogen-free, and fully compliant with RoHS and WEEE directives. Its molding compound meets UL 94V-0 flammability rating, and lead finish is lead-free, supporting environmentally regulated industrial and consumer deployments without exemption requests.
