Product details
Overview
PCLAMP2011P.TGT from Semtech is a transient diverting suppressor designed for high-energy EOS protection of 22V-rated power or I/O lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A (8/20μs) peak pulse current handling, and stable 27.5–28V clamping voltage across temperature and current range; used in USB Type-C PD bus protection.
For engineers reviewing the PCLAMP2011P.TGT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under surge, low dynamic resistance (<20 mΩ), junction capacitance (175 pF), and DFN 1.6×1.6mm 6-lead package compatibility with high-density USB and industrial layouts.
Technical Context
The PCLAMP2011P.TGT implements a surge-rated FET shunt architecture with precision trigger circuitry-unlike conventional TVS diodes-enabling near-constant clamping voltage independent of peak pulse current (24–40A) and operating temperature (−40°C to +125°C). Its RDYN of 20 mΩ ensures minimal voltage rise during transients.
It operates as a bidirectional, single-line protector with reverse stand-off voltage (VRWM) of 22 V, breakdown voltage (VBR) of 25–27.9 V, and reverse leakage <600 nA at 22 V. The device conducts surge current to ground via three parallel IN pins (4–6) and three GND pins (1–3), requiring full pin connection for rated 40A performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22 V - defines maximum continuous DC or RMS operating voltage on protected line without leakage or conduction. |
| Clamping Voltage | 27.5–28 V at 40A (8/20μs + 1.2/50μs combo wave, RS = 2 Ω) - ensures downstream 24V-rated ICs (e.g., USB PD controllers) remain below damage threshold during surge. |
| Peak Pulse Current | 40 A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements for 22V systems. |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - exceeds Level 4 immunity for handheld and interface connectors. |
| Junction Capacitance | 175 pF at 22 V, 1 MHz - compatible with USB PD power bus (not signal lines); requires separate low-C TVS for SS/DP/DM lanes. |
| Dynamic Resistance | 20 mΩ (measured 1–40A, 8/20μs) - enables flat clamping curve and minimizes IR drop during high-current transients. |
Pinout & Package
Package: DFN 1.6 mm × 1.6 mm × 0.55 mm, 6-lead, Pb-free, RoHS/WEEE compliant, UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path; all three must be connected to minimize inductance and enable full 40A surge rating. |
| 4, 5, 6 | IN | Protected line input (bidirectional); tied together externally to connect to VBus or power rail; all three required for rated performance. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based shunt architecture | Enables constant clamping voltage across 24–40A and −40°C to +125°C-unlike TVS diodes whose VC rises linearly with IPP and temperature. |
| Low dynamic resistance | 20 mΩ ensures <0.8 V additional drop at 40A, preserving tight clamping margin for 24V system components. |
| High-energy surge rating | 1120 W peak pulse power (8/20μs) supports robust protection against lightning-induced surges per IEC 61000-4-5. |
| Ultra-low leakage | ≤600 nA at 22 V enables use in always-on, low-power industrial and IoT applications without battery drain impact. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V VBus lines in USB-C receptacles supporting up to 100W PD, exposed to ESD and surge events during hot-plug or cable coupling. IC Role / Device Role / Timing Role: Primary high-energy EOS suppressor placed adjacent to connector, clamping transients before they reach PD controller or load switch. Use Value: Maintains 27.5–28V clamping across temperature-prevents overvoltage damage to 24V-rated PD controllers where conventional TVS would exceed 35V at 125°C. |
Use Scenario: Safeguarding input terminals of industrial-grade load switches (e.g., HS2950P) in remote meters, robotics, or factory automation equipment subject to lightning-induced surges. 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: Clamps to ≤28V at 40A, staying well below typical 30–36V absolute max ratings of load switch inputs-extending reliability in harsh environments. |
| IoT Edge Node Power Rail Protection | Storage Device 22V Backup Power Line Protection |
Use Scenario: Securing 22V auxiliary rails in battery-backed IoT gateways or edge AI nodes deployed outdoors or in unshielded enclosures. IC Role / Device Role / Timing Role: Single-component, space-efficient solution replacing multi-device TVS+MOV stacks for compact, thermally stable protection. Use Value: 1.6×1.6mm DFN footprint saves >60% board area vs. SOT-23 TVS alternatives while delivering superior thermal stability over −40°C to +125°C operating range. |
Use Scenario: Protecting 22V backup power inputs in enterprise SSDs or NAS storage units during AC mains transients or hot-swap events. IC Role / Device Role / Timing Role: High-reliability clamping element ensuring backup rail stays within safe operating voltage window during 1kV/42Ω surge tests. Use Value: Rated for ±1kV (1.2/50μs, RS=42Ω) per IEC 61000-4-5-meets industrial storage EMC compliance requirements without derating at elevated ambient temperatures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P.C | Same silicon die, identical electrical specs, identical DFN 1.6×1.6mm package; differs only in tape-and-reel packaging (3,000 pcs/reel vs. PCLAMP2011P.TGT's unspecified reel quantity). | No functional difference; suitable for same PCB layout and schematic design. | Select TDS2211P.C when standard Semtech reel quantity (3k) aligns with production planning; PCLAMP2011P.TGT may reflect custom distribution packaging. |
| uClamp2411ZA.TCT | 24V working voltage, lower 24A peak pulse rating, higher 30V clamping (typ.), 0.25pF capacitance-designed for CC/SBU lines, not power rails. | Intended for low-capacitance data/control line protection-not a power bus replacement; unsuitable for 40A surge duty. | Use uClamp2411ZA.TCT only for USB-C CC/SBU protection; PCLAMP2011P.TGT remains required for VBus and load switch inputs. |
Compared with TDS2211P.C, PCLAMP2011P.TGT offers identical protection performance and layout compatibility; versus uClamp2411ZA.TCT, it delivers 67% higher surge current rating and 2.5× lower clamping voltage-but at 700× higher capacitance, making it unsuitable for high-speed signal lines.

FAQ
What is the maximum continuous operating voltage for PCLAMP2011P.TGT?
The PCLAMP2011P.TGT has a reverse stand-off voltage (VRWM) of 22 V, meaning it can continuously withstand up to 22 V DC or RMS on its IN pins without significant leakage or conduction. This makes it suitable for 20V USB PD VBus and other 22V-rated power rails. Exceeding this voltage risks premature triggering or accelerated degradation.
Does PCLAMP2011P.TGT require external bias or control signals to operate?
No, the PCLAMP2011P.TGT is a fully passive, self-triggering device. It contains an integrated precision trigger circuit and surge-rated FET-no external power, enable pin, or configuration is needed. The PCLAMP2011P.TGT activates automatically when transient voltage exceeds its breakdown threshold (~25–27.9 V), diverting surge current to ground.
Can PCLAMP2011P.TGT be used on high-speed data lines like USB SuperSpeed or PCIe?
No, the PCLAMP2011P.TGT is not suitable for high-speed data lines due to its 175 pF junction capacitance, which would severely degrade signal integrity. It is designed exclusively for power or low-frequency I/O lines. For USB SS, DP/DM, or PCIe lanes, Semtech recommends low-capacitance devices such as RClamp3371ZC (<0.25 pF), not the PCLAMP2011P.TGT.
How should the six pins of PCLAMP2011P.TGT be routed on the PCB?
All three IN pins (4, 5, 6) must be shorted together with a low-inductance trace to the protected line (e.g., VBus), and all three GND pins (1, 2, 3) must connect directly to a solid ground plane using multiple vias. The PCLAMP2011P.TGT must be placed within 5 mm of the connector-any stub or routing inductance degrades surge response. Do not float or omit any pin.
Is PCLAMP2011P.TGT RoHS and REACH compliant?
Yes, the PCLAMP2011P.TGT is Pb-free, halogen-free, and compliant with both RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Its molding compound meets UL 94V-0 flammability rating, and lead finish is 100% matte tin-fully aligned with industrial and consumer environmental compliance requirements.
