Product details
Overview
TS30012-M050QFNR 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. It is used in USB Type-C PD input protection where low, temperature-invariant clamping prevents damage to downstream controllers.
For engineers reviewing the TS30012-M050QFNR datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability over 40A surge current, DFN-6 thermal and layout performance, 22V working voltage compliance, and solid-state FET-based transient diversion versus conventional TVS diodes.
Technical Context
The TS30012-M050QFNR uses a precision-triggered surge-rated FET as its primary protection element, activated by a dedicated trigger circuit when transient voltage exceeds breakdown. Unlike standard TVS diodes, its clamping voltage remains nearly constant-27.5–28V-across 24A to 40A peak pulse current due to decreasing RDS(on) under surge conditions.
It operates from −40°C to +125°C with <20mΩ dynamic resistance and 175pF junction capacitance at 22V reverse bias. The device protects one line (IN-to-GND), requires all three IN pins (4–6) and all three GND pins (1–3) to be connected for full 40A rating, and dissipates energy in the FET channel-not the junction-enabling superior thermal stability.
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 automotive and industrial ESD robustness standards |
| Junction Capacitance | 175pF at 22V - low enough for 22V power rail protection without signal integrity impact on adjacent traces |
| Dynamic Resistance | 20mΩ - enables flat clamping curve and minimizes voltage overshoot during fast-rising transients |
| Package | DFN 1.6 × 1.6 × 0.55 mm, 6-lead - enables ultra-compact placement near connectors with minimal PCB area |
Pinout & Package
TS30012-M050QFNR is housed in a Pb-free, RoHS-compliant DFN-6 package (1.6 mm × 1.6 mm × 0.55 mm) with exposed thermal pad not required-energy is dissipated in the FET channel. All six terminals must be soldered: three GND pins provide low-inductance return path; three IN pins share surge current to achieve full 40A rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground reference for trigger circuit and shunt FET source; all three must be connected to minimize ground loop inductance |
| Pins 4, 5, 6 | IN | Protected line input (e.g., VBUS in USB-C); parallel connection distributes surge current and reduces per-pin current density |
Key Features
| Feature | Design Value |
|---|---|
| FET-based transient diversion | Replaces conventional TVS diode with active shunt switch, enabling constant clamping independent of surge amplitude |
| Temperature-stable clamping | 27.5–28V clamping maintained from −40°C to +125°C-no derating needed for high-temp industrial environments |
| High-energy surge handling | 1120W peak pulse power (8/20μs) supports repeated lightning-surge events without parametric shift |
| Low dynamic resistance | 20mΩ ensures minimal IR drop during 40A surge, preserving clamping accuracy and reducing localized heating |
| Ultra-low leakage | ≤600nA at 22V reverse bias-prevents measurable power loss in always-on 22V systems like battery-backed IoT nodes |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Input Protection |
|---|---|

IC Role / Device Role / Timing Role: Standalone EOS protector for non-data, high-voltage supply lines feeding PMICs or sensor subsystems. Use Value: 175pF capacitance and <600nA leakage avoid loading sensitive 22V bias networks while delivering ±30kV ESD immunity. |
Use Scenario: Shielding 22V power inputs in NVMe SSD enclosures and enterprise storage backplanes from system-level surges. IC Role / Device Role / Timing Role: High-power transient diverter on main power entry point upstream of DC-DC converters. Use Value: 1120W peak power rating and DFN-6 footprint enable robust, space-constrained protection without heatsinking or board real estate penalty. |
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 pin-to-pin and functional replacement per Semtech documentation | No change in layout, BOM, or test plan required; validated for USB-C PD and load switch use cases | Select when exact Semtech-recommended second-source or alternate date-code availability is needed |
| SMAJ22A | Standard unidirectional TVS diode; 22V standoff, 35.5V min clamping at 12.5A (8/20μs); no temperature-stable clamping; 1.5× higher clamping voltage at rated current | Requires derating above 85°C; unsuitable for 22V systems with tight clamping margins (e.g., USB PD) | Consider only for cost-sensitive, non-critical 22V lines where 35.5V+ clamping is acceptable and temperature range is limited |
Compared with TDS2211P and SMAJ22A, TS30012-M050QFNR offers identical performance and drop-in compatibility to TDS2211P but differs from SMAJ22A in core architecture-its FET-based design delivers 8V lower clamping at 40A and stable performance across −40°C to +125°C, making it essential for high-reliability 22V power rail protection.

FAQ
What is the clamping voltage behavior of TS30012-M050QFNR under varying surge currents?
The TS30012-M050QFNR maintains a tightly regulated clamping voltage of 27.5–28V across its full rated peak pulse current range (24A to 40A, 8/20μs), unlike conventional TVS diodes whose clamping rises linearly with current. This stability results from its FET-based architecture, where RDS(on) decreases under surge, counteracting voltage rise. TS30012-M050QFNR achieves this performance from −40°C to +125°C without derating.
Is TS30012-M050QFNR pin-compatible with TDS2211P?
Yes, TS30012-M050QFNR is pin-compatible and functionally identical to TDS2211P: both use the same DFN-6 (1.6 × 1.6 × 0.55 mm) package, identical pinout (Pins 1–3 = GND, Pins 4–6 = IN), and match all key electrical parameters including 22V working voltage, 40A peak pulse current, and 27.5–28V clamping. TS30012-M050QFNR is a direct second-source variant confirmed by Semtech documentation.
Can TS30012-M050QFNR protect bidirectional data lines like USB DP/DM?
No, TS30012-M050QFNR is designed exclusively for unidirectional 22V power or I/O line protection (IN-to-GND). Its architecture does not support bidirectional clamping or low-capacitance (<0.5pF) requirements of high-speed data lines. For USB SuperSpeed lanes, Semtech recommends RClamp3371ZC; for CC/SBU lines, uClamp2411ZA. TS30012-M050QFNR must be used only on VBUS or other single-polarity 22V rails.
What PCB layout practices maximize surge performance for TS30012-M050QFNR?
To maximize surge performance, place TS30012-M050QFNR within 3 mm of the protected connector. Connect all three IN pins (4–6) via a single short, wide trace to the protected line, and tie all three GND pins (1–3) directly to a solid ground plane using ≥3 vias. Avoid thermal pads-energy is dissipated in the FET channel, not the die junction. This layout minimizes parasitic inductance and ensures full 40A capability.
Does TS30012-M050QFNR require external components for basic operation?
No, TS30012-M050QFNR is a fully self-contained transient suppressor requiring no external resistors, capacitors, or bias networks. Its integrated trigger circuit and shunt FET operate autonomously upon detection of overvoltage. Only proper PCB layout-short IN/GND traces and low-inductance grounding-is needed. TS30012-M050QFNR functions immediately after soldering with no configuration or calibration.
