Product details
Overview
TS30012-M033QFNR 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 voltage overshoot.
For engineers reviewing the TS30012-M033QFNR datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability over 40A surge current, DFN-6 thermal robustness up to +125°C, low dynamic resistance (20mΩ), and compatibility with industrial load switch input protection layouts.
Technical Context
The TS30012-M033QFNR uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit when transient voltage exceeds breakdown threshold. Unlike conventional TVS diodes, its clamping voltage remains nearly constant due to decreasing RDS(on) under surge, not fixed dynamic resistance.
It operates as a shunt device between protected line (pins 4–6) and ground (pins 1–3), with functional behavior defined by VBR ≈ 27.9V (typ), VRWM = 22V, and guaranteed clamping at 28V under 40A (8/20μs + 1.2/50μs combination waveform, RS = 2Ω).
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 @ 40A - ensures downstream ICs (e.g., USB PD controllers) remain below damage threshold during worst-case surge |
| 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 test levels |
| Dynamic Resistance | 20mΩ - enables low-voltage drop during conduction, minimizing power dissipation and thermal stress |
| Junction Capacitance | 175pF @ 22V, 1MHz - suitable for DC/low-speed power line protection; not for high-speed data lines |
Pinout & Package
TS30012-M033QFNR is housed in a RoHS-compliant DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no internal thermal pad required; energy dissipated in silicon). All six pins must be connected for full 40A rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; multiple vias recommended to minimize inductance |
| Pins 4, 5, 6 | IN | Parallel-connected input terminals for protected line; all three must be routed to same net for rated IPP performance |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping voltage | 27.5–28V across 24–40A and −40°C to +125°C - eliminates derating concerns in thermally demanding environments |
| Low dynamic resistance | 20mΩ - reduces voltage overshoot during fast-rising transients and minimizes self-heating |
| High-energy surge handling | 1120W peak pulse power - supports repeated lightning-induced surges per IEC 61000-4-5 |
| Ultra-low leakage | 600nA max @ 22V - prevents system standby current degradation in battery-powered IoT devices |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting VBus lines in USB-C receptacles supporting up to 20V PD negotiation. IC Role / Device Role / Timing Role: Shunt-based transient suppressor placed immediately at connector entry point to divert EOS before reaching PD controller. Use Value: Maintains 28V clamping at full 40A surge and +125°C ambient-prevents controller latch-up or gate oxide damage where standard TVS would exceed 35V. | Use Scenario: Safeguarding enable and input rails of industrial-grade load switches (e.g., HS2950P) in remote meters and robotics. IC Role / Device Role / Timing Role: Primary front-end EOS clamp on VIN rail, coordinated with internal OVP and UVLO functions of the load switch. Use Value: Keeps clamping voltage below the FET's absolute maximum VDS, avoiding destructive avalanche failure during 1kV/42Ω surges. |
| IoT Device Power Rail Protection | Notebook/Tablet DC Input Protection |
Use Scenario: Securing 22V-rated auxiliary power inputs in battery-backed smart sensors and edge gateways. IC Role / Device Role / Timing Role: Standalone EOS protector on main DC input, operating independently of PMIC sequencing. Use Value: 175pF capacitance avoids signal integrity issues on low-frequency power paths while delivering ±30kV ESD robustness for field-deployed units. | Use Scenario: Reinforcing 20V DC-in protection in ultraportable notebooks and tablets with compact power adapters. IC Role / Device Role / Timing Role: Secondary surge suppression stage after bulk filtering, complementing upstream ceramic varistors. Use Value: DFN-6 footprint (1.6×1.6mm) saves >60% board area versus SO-8 TVS solutions-critical for thin-profile PCB stacking. |
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 and reel packaging | Direct second-source part; fully interchangeable with TS30012-M033QFNR in all designs | Select when dual-sourcing or extended lead time mitigation is required |
| uClamp2411ZA | 24V working voltage, lower 20A IPP rating, higher 33V clamping, SOD-323 package | Targeted at CC/SBU lines-not suitable for 22V VBus protection due to insufficient surge margin | Use only for auxiliary signal-line protection; not a functional replacement for TS30012-M033QFNR |
Compared with TDS2211P, TS30012-M033QFNR offers identical performance and form factor-enabling seamless dual sourcing. Versus uClamp2411ZA, TS30012-M033QFNR provides 2× higher surge current rating and 5V lower clamping, making it the sole qualified choice for 22V power rail EOS protection.

FAQ
What is the maximum continuous operating voltage for TS30012-M033QFNR?
The TS30012-M033QFNR has a reverse stand-off voltage (VRWM) of 22V, meaning it reliably blocks up to 22V DC under normal operation with leakage <600nA. Exceeding this voltage risks premature triggering or accelerated wear. This rating aligns with USB PD 20V nominal + 10% tolerance and industrial 24V rail derating requirements.
Does TS30012-M033QFNR require a thermal pad on the PCB?
No, TS30012-M033QFNR does not require an external thermal pad. Its DFN-6 package dissipates surge energy directly through the silicon die and ground pins (1–3); layout guidelines emphasize low-inductance grounding via multiple vias-not copper pour. The datasheet explicitly states "no thermal pad is needed" under transient conditions.
Can TS30012-M033QFNR be used on high-speed data lines like USB SuperSpeed?
No, TS30012-M033QFNR is not suitable for USB SuperSpeed (SS), DisplayPort, or other high-speed differential pairs. Its 175pF junction capacitance would severely degrade signal integrity. It is intended exclusively for DC or low-frequency power/data lines (e.g., VBus, CC, SBU, load switch inputs). For SS lines, Semtech recommends RClamp3371ZC (<0.25pF).
How does TS30012-M033QFNR differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN), TS30012-M033QFNR uses a triggered FET architecture that maintains ~28V clamping from 24A to 40A and across −40°C to +125°C. This eliminates thermal derating and ensures consistent protection margins in real-world operating conditions.
Is TS30012-M033QFNR compatible with lead-free reflow processes?
Yes, TS30012-M033QFNR is Pb-free, halogen-free, and RoHS/WEEE compliant. Its DFN-6 package supports standard JEDEC J-STD-020D reflow profiles, including peak temperatures up to 260°C. The lead finish is matte tin, and the molding compound meets UL 94V-0 flammability rating.
