Product details
Overview
TS30042-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 temperature and current range. Used in USB Type-C PD input protection to safeguard controllers from bus overvoltage.
For engineers reviewing the TS30042-M000QFNR datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under 40A surge, DFN-6 thermal and layout performance, 22V working voltage compliance, and low dynamic resistance (20mΩ) for minimal voltage overshoot during fast transients.
Technical Context
The TS30042-M000QFNR uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events. Unlike conventional TVS diodes, its clamping voltage remains nearly constant-27.5–28V at both 24A and 40A-due to decreasing RDS(on) under surge conditions.
It operates across –40°C to +125°C with <600nA reverse leakage at 22V and 175pF junction capacitance at 1MHz/22V. The device requires all three IN pins (4–6) and all three GND pins (1–3) connected in parallel to achieve full 40A rating and minimize parasitic inductance.
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 see ≤28V during worst-case surge, critical for 30V-tolerant USB PD controllers |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds USB-IF and industrial ESD immunity mandates |
| Dynamic Resistance | 20mΩ - enables flat clamping response and minimizes voltage rise ΔV = I × RDYN during surge |
| Junction Capacitance | 175pF at 22V/1MHz - low enough for 22V power rail protection without signal integrity impact |
Pinout & Package
TS30042-M000QFNR 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). All six terminals are surface-mount; no lead finish other than matte tin.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current; all three must be shorted and vias used to internal ground plane for 40A capability |
| 4, 5, 6 | IN | Parallel-connected input terminals for protected line; equal current sharing required to avoid imbalance and localized heating |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies <0.5V from 24A to 40A - eliminates need for derating at high temperature or current |
| FET-based shunt topology | Replaces PN-junction TVS with <0.1Ω RDS(on) - reduces energy dissipation in silicon junction, improving reliability under repeated surges |
| Low dynamic resistance | 20mΩ measured between 1A–40A - ensures predictable, linear VC = VBR + IPP×RDYN behavior with minimal overshoot |
| High-temperature stability | Clamping holds 27–28V from –40°C to +125°C - enables robust operation in automotive cabin or industrial enclosures |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20V–22V VBUS lines in USB-C receptacles against lightning-induced surges and connector hot-plug ESD. IC Role / Device Role / Timing Role: Primary EOS shunt suppressor placed directly at connector, diverting >95% of 40A transient current to ground before reaching PD controller. Use Value: Maintains 27.5–28V clamping across full temperature range-prevents false OVP trips and avoids overdesigning PD controller voltage tolerance. |
Use Scenario: Safeguarding enable and input pins of high-side load switches (e.g., HS2950P) in remote meters and robotics against 1kV/42Ω surges. IC Role / Device Role / Timing Role: Front-end transient clamp limiting voltage seen by internal FET gate oxide and sense resistors during EOS events. Use Value: Prevents permanent damage to load switch's internal FET by holding clamping voltage below 30V absolute max rating, even at 125°C ambient. |
| IoT Edge Node Power Rail Protection | Notebook/Tablet DC-In Protection |
Use Scenario: Securing 12–24V DC input rails of battery-powered IoT gateways exposed to field ESD and induced surges via long cables. IC Role / Device Role / Timing Role: Single-device solution replacing multi-stage TVS+MOV networks, reducing BOM count and PCB area by >60%. Use Value: 1.6mm × 1.6mm footprint saves board space vs. SOD-123 or SMA packages while delivering higher surge rating than comparably sized TVS. |
Use Scenario: Protecting 20V DC-in ports on ultrabooks and tablets against accidental adapter misconnection and ESD during user handling. IC Role / Device Role / Timing Role: Fast-acting shunt clamp responding within nanoseconds to limit voltage excursion before system PMIC or buck converter input stage. Use Value: 175pF capacitance avoids resonance with typical 10–100μF bulk input capacitors, eliminating risk of ringing-induced overvoltage. |
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 - confirmed direct replacement per Semtech documentation | No functional difference; same pinout, marking, and thermal profile | Select TS30042-M000QFNR when requiring QFN-compatible tape-and-reel packaging with updated traceability coding |
| SMAJ22A | Standard unidirectional TVS diode; 33.2V min clamping at 24.7A, 100mΩ dynamic resistance, 1000pF capacitance | Larger SMC package (7.1mm × 6.2mm); unsuitable for space-constrained USB-C designs | Use only where board area is unconstrained and clamping voltage margin >11V is acceptable |
Compared with TDS2211P, TS30042-M000QFNR offers identical protection performance in an updated packaging format; compared with SMAJ22A, it delivers 10× lower clamping voltage variation, 5× lower dynamic resistance, and 80% smaller footprint-enabling compact, thermally robust EOS protection where space and precision clamping are critical.

FAQ
What is the exact package type and dimensions of TS30042-M000QFNR?
TS30042-M000QFNR uses a 6-pin DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad. Pin pitch is 0.5mm, and the land pattern follows Semtech's recommended layout in the TDS2211P datasheet (Rev 2.5, page 7). All six terminals are surface-mount; no leads or gull-wing features are present. The package is Pb-free, halogen-free, and RoHS/WEEE compliant.
Does TS30042-M000QFNR require external bias or control signals to operate?
No, TS30042-M000QFNR is fully passive and self-triggering. It contains an integrated precision trigger circuit and surge-rated FET that activate automatically when input voltage exceeds the breakdown threshold (~27.9V). No external power, enable pin, or configuration is needed-operation is immediate and autonomous upon transient detection.
Can TS30042-M000QFNR be used on bidirectional data lines like USB DP/DM?
No, TS30042-M000QFNR is designed exclusively for unidirectional power or single-ended I/O line protection. Its 22V working voltage and 27.5–28V clamping are optimized for VBUS or load switch inputs-not low-voltage, high-speed differential pairs. For DP/DM lines, Semtech recommends RClamp3371ZC (<0.25pF, 3.3V-rated) instead of TS30042-M000QFNR.
How does TS30042-M000QFNR's clamping performance compare to standard TVS diodes at high temperature?
At 125°C, TS30042-M000QFNR maintains 27.5–28V clamping across 24–40A, whereas standard TVS diodes (e.g., SMAJ22A) exhibit >38V clamping due to positive temperature coefficient of VBR and fixed RDYN. This 10V+ margin prevents overvoltage damage to downstream ICs in thermally demanding environments where TS30042-M000QFNR delivers predictable, stable protection.
Is TS30042-M000QFNR pin-compatible with TDS2211P?
Yes, TS30042-M000QFNR is pin-compatible and functionally identical to TDS2211P-same 6-pin DFN-1616 package, identical pinout (pins 1–3 = GND, pins 4–6 = IN), and matching electrical specifications per Semtech's datasheet Rev 2.5. The part number change reflects updated packaging and traceability coding, not functional revision.
