Product details
Overview
PCLAMP1011P.TGT from Semtech is a transient diverting suppressor designed for high-energy EOS protection of 22V-rated I/O or power lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A (8/20μs) peak pulse current handling, 27.5–28V clamping voltage at 40A, and DFN 1.6×1.6×0.55mm 6-lead package - deployed in USB Type-C PD bus protection and industrial load switch input stages.
For engineers reviewing the PCLAMP1011P.TGT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability across temperature and current, dynamic resistance <20mΩ, junction capacitance ≤175pF at 22V, and compatibility with high-speed interface protection schemes requiring low parasitic impact.
Technical Context
The PCLAMP1011P.TGT implements a surge-rated FET as its primary protection element, activated by a precision trigger circuit that turns on the shunt path when transient voltage exceeds breakdown threshold. Unlike conventional TVS diodes, its clamping voltage remains nearly constant (27.5–28V) from 24A to 40A due to decreasing RDS(on) under surge conditions.
It operates over –40°C to +125°C, maintains <600nA reverse leakage at 22V, and delivers 1120W peak pulse power (8/20μs). Its functional architecture decouples clamping performance from junction heating effects, enabling stable protection in thermally constrained industrial and portable applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC operating voltage on protected line without leakage or conduction. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo waveform) - ensures downstream 24V-rated ICs (e.g., USB PD controllers) remain below damage threshold during surge. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements for 22V systems. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD robustness standards without derating. |
| Dynamic Resistance | 20mΩ - enables low-voltage drop during high-current transients, minimizing energy dissipation in the device itself. |
| Junction Capacitance | 175pF at 22V, 1MHz - compatible with medium-speed data/power lines (e.g., USB PD VBUS, load switch inputs), not superspeed lanes. |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, Pb-free, RoHS/WEEE compliant, UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1, 2, 3 | GND | Common ground connection terminals - all three must be soldered to maximize surge current return path and minimize inductance. |
| Pin 4, 5, 6 | IN | Protected line input terminals - connected in parallel to the 22V bus or power rail; all three required for full 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies <0.5V across 24–40A surge range - eliminates need for overrating IPP to meet voltage margin. |
| Temperature-stable clamping | 27.5–28V clamping maintained from –40°C to +125°C - removes thermal derating calculations for industrial ambient conditions. |
| Low dynamic resistance | 20mΩ measured between 1A–40A - reduces self-heating and improves surge survivability vs. TVS diodes with fixed RDYN. |
| High-energy EOS protection | 1120W peak pulse power (8/20μs) - supports repeated surges per IEC 61000-4-5 without parameter drift or degradation. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V VBUS lines in USB-C PD ports against lightning-induced surges and connector hot-plug ESD. IC Role / Device Role / Timing Role: Transient diverting suppressor placed directly at connector entry point, shunting surge current to ground before reaching PD controller or e-fuse. Use Value: Maintains 27.5–28V clamping across temperature and current - prevents overvoltage damage to 24V-tolerant PD controllers without requiring oversized TVS devices. |
Use Scenario: Safeguarding input pins of industrial-grade load switches (e.g., HS2950P) in remote meters, robotics, and IoT edge nodes. IC Role / Device Role / Timing Role: Primary front-end EOS protector on VIN rail, limiting transient voltage seen by internal FET gate oxide and overvoltage protection circuitry. Use Value: Clamps below 28V at 40A while dissipating minimal energy in silicon - extends load switch lifetime and avoids false OVP shutdown during surge events. |
| Storage Device Power Rail Protection | Notebook/Tablet 22V System Bus Protection |
Use Scenario: Securing 22V auxiliary rails in NVMe SSD enclosures and enterprise storage backplanes exposed to system-level ESD and coupling noise. IC Role / Device Role / Timing Role: Standalone EOS suppressor on 22V power distribution network, coordinated with low-capacitance TVS on high-speed lanes. Use Value: 175pF junction capacitance avoids signal integrity impact on adjacent PCIe or SATA traces - enables co-location without layout compromise. |
Use Scenario: Protecting 22V system rails in ultrabooks and tablets where space-constrained PCBs require minimal-footprint, high-reliability surge suppression. IC Role / Device Role / Timing Role: Compact DFN-based transient suppressor mounted adjacent to power connectors or battery charge circuits. Use Value: 1.6×1.6mm footprint saves >60% board area vs. legacy SO-8 TVS solutions - critical for thin-profile consumer electronics. |
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 manufacturer, identical electrical specs and package - direct replacement with identical marking and reel packaging. | Identical use case coverage: USB-C PD, load switch input, industrial 22V rails. | Select when sourcing from Semtech's standard product line with full traceability and lifecycle support. |
| uClamp2411ZA | 24V working voltage, lower 24A IPP rating, higher 33V clamping at 24A, smaller 0.6×0.6mm 2-pin DFN package. | Targeted at CC/SBU lines in USB-C, not main VBUS - insufficient for 40A surge or 22V bus protection. | Use only for auxiliary signal lines; not a functional substitute for PCLAMP1011P.TGT in power rail roles. |
Compared with TDS2211P and uClamp2411ZA, PCLAMP1011P.TGT offers identical core protection performance to TDS2211P but may differ in tape-and-reel packaging or date-code marking conventions, whereas uClamp2411ZA serves distinct low-capacitance, low-current signal-line roles and cannot replace PCLAMP1011P.TGT in 22V power rail applications.

FAQ
What is the maximum continuous operating voltage for PCLAMP1011P.TGT?
The PCLAMP1011P.TGT has a reverse stand-off voltage (VRWM) of 22V, meaning it can continuously block up to 22V DC without significant leakage or conduction. This makes it suitable for protecting 22V-rated buses such as USB-C Power Delivery VBUS lines and industrial 22V power rails. Exceeding this voltage risks premature conduction and accelerated wear.
Does PCLAMP1011P.TGT require external bias or control signals to operate?
No, PCLAMP1011P.TGT is a fully passive, self-triggering device. It contains an integrated precision trigger circuit and surge-rated FET that activate automatically when transient voltage exceeds the internal breakdown threshold. No external power, enable pins, or configuration are needed - it functions immediately upon installation in-circuit.
How does PCLAMP1011P.TGT differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with peak pulse current (VC = VBR + IPP × RDYN), PCLAMP1011P.TGT maintains a near-constant clamping voltage of 27.5–28V from 24A to 40A due to its FET-based architecture and decreasing RDS(on). This eliminates the need to overspecify IPP to meet voltage margins.
Can PCLAMP1011P.TGT be used on high-speed data lines like USB SuperSpeed or PCIe?
No, PCLAMP1011P.TGT is not suitable for high-speed data lanes. Its 175pF junction capacitance at 22V would severely degrade signal integrity on >5Gbps interfaces. It is intended for power lines and medium-speed control signals (e.g., USB-C CC, SBU, or load switch enable inputs), where low capacitance is not critical.
What is the recommended PCB layout for optimal surge performance of PCLAMP1011P.TGT?
For best results, place PCLAMP1011P.TGT as close as possible to the protected connector. Connect all three IN pins (4, 5, 6) via a single short, wide trace to the protected line, and tie all three GND pins (1, 2, 3) directly to a solid ground plane using multiple vias. Avoid stubs or routing gaps - parasitic inductance degrades clamping response during fast ESD events.
