Product details
Overview
PCLAMP0511ZVTFT from Semtech is a transient diverting suppressor designed to protect single 5V I/O or power lines against EOS, ESD, and EFT events. It features ±30kV IEC 61000-4-2 contact/air ESD immunity, 24A peak pulse current (8/20μs), 9.5V clamping voltage at 24A, 0.55pF junction capacitance, and operates in a 1.0mm × 0.6mm DFN-6 package - ideal for high-speed USB 2.0 and HDMI signal line protection.
For engineers reviewing the PCLAMP0511ZVTFT datasheet, pinout, applications, or equivalent options, key selection criteria include low clamping voltage under surge, sub-1pF capacitance for signal integrity, DFN-6 footprint compatibility with space-constrained layouts, and verified IEC 61000-4-2/4-4/4-5 compliance for industrial and consumer interface protection.
Technical Context
PCLAMP0511ZVTFT employs a precision-triggered shunt FET architecture rather than conventional PN-junction TVS diodes, enabling near-constant clamping voltage across its rated surge current range (1–24A) and operating temperature (−40°C to +125°C). Its dynamic resistance is <0.1Ω, resulting in minimal voltage rise during transients.
The device integrates three parallel input terminals (pins 4–6) and three ground terminals (pins 1–3) to maximize surge current handling and minimize parasitic inductance. Its ultra-low 0.55pF capacitance at VR = 5V ensures minimal signal distortion on high-speed data lines up to 480 Mbps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 5 V - matches standard USB 2.0, HDMI, and LVDS supply rails without derating. |
| Clamping Voltage | 9.5 V at IPP = 24 A (8/20 μs) - stays below 10 V across full surge range, protecting 5V logic interfaces. |
| Junction Capacitance | 0.55 pF at VR = 5 V, f = 1 MHz - preserves signal integrity on 480 Mbps USB 2.0 and 1.65 Gbps HDMI 1.4a links. |
| ESD Withstand | ±30 kV contact & air per IEC 61000-4-2 - exceeds Level 4 immunity requirements for handheld and portable devices. |
| Peak Pulse Current | 24 A (tp = 8/20 μs) per IEC 61000-4-5 - handles common industrial surge threats including indirect lightning coupling. |
| Package | DFN-6, 1.0 mm × 0.6 mm × 0.4 mm - enables placement within 2 mm of USB/HDMI connectors for optimal transient suppression. |
Pinout & Package
Package: DFN-6, 1.0 mm × 0.6 mm × 0.4 mm, Pb-free, RoHS-compliant, UL 94V-0 molding compound, bottom thermal pad not required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Ground | Three dedicated low-inductance GND connections - must all be soldered to solid ground plane for full 24A surge rating. |
| 4, 5, 6 | Input/Protected Line | Parallel-connected anode-side terminals - connect directly to protected signal/power line; shared clamping path to ground. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based clamping | Enables flat 9.5 V clamping from 1 A to 24 A - avoids voltage overshoot that damages 5V USB PHYs and HDMI receivers. |
| Sub-1pF capacitance | 0.55 pF at 5 V - eliminates measurable eye diagram degradation on USB 2.0 full-speed signals (480 Mbps). |
| Triple-terminal I/O & GND | Three parallel pins per side reduce trace inductance by >50% vs. single-pin equivalents - critical for ESD rise-time suppression (<1 ns). |
| −40°C to +125°C stability | Clamping voltage drift <±0.2 V over full temp range - ensures consistent protection in automotive cabin and industrial edge environments. |
Applications
| USB 2.0 Data Lines | HDMI DDC/CEC Lines |
|---|---|
Use Scenario: Protecting DP/DM lines of USB 2.0 ports in notebooks and docking stations against ESD from user insertion/removal. IC Role / Device Role / Timing Role: Low-capacitance transient suppressor placed between connector and USB transceiver PHY. Use Value: 0.55 pF capacitance prevents signal rise/fall time degradation; 9.5 V clamping prevents latch-up in 5V-tolerant PHY inputs. | Use Scenario: Shielding HDMI DDC (I²C) and CEC control lines from ESD during cable hot-plug in AV receivers and smart displays. IC Role / Device Role / Timing Role: Bidirectional EOS protector on 5V-tolerant I²C bus operating at 100 kHz–400 kHz. Use Value: ±30 kV ESD rating meets IEC 61000-4-2 Level 4; 9.5 V clamping keeps voltage below 10 V threshold of HDMI controller GPIOs. |
| Industrial Sensor Interfaces | USB-C CC Line Protection |
Use Scenario: Safeguarding 5V RS-485 or CAN FD transceiver I/O pins in factory automation gateways exposed to EFT bursts. IC Role / Device Role / Timing Role: Unidirectional shunt suppressor on 5V bias rail feeding isolated interface ICs. Use Value: 24A surge rating handles IEC 61000-4-4 EFT (±4 kV, 5/50 ns); stable clamping prevents false triggering of fault detection circuits. | Use Scenario: Protecting USB-C Configuration Channel (CC) pins in host/port controllers against miswiring-induced 5V surges and ESD. IC Role / Device Role / Timing Role: Low-leakage (IR < 100 nA) suppressor on bidirectional 5V CC line with pull-up/pull-down resistors. Use Value: 0.55 pF capacitance avoids skewing CC voltage detection timing; 9.5 V clamping prevents damage to CC logic circuitry. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RClamp0524P.TCT | Clamps at 12.5 V (IPP = 24 A); 0.3 pF capacitance; same DFN-6 (1.0 × 0.6 mm) package. | Higher clamping voltage limits use with 5V logic having tight VIH/VIL margins; lower capacitance suits >1 Gbps interfaces. | Select when lowest possible capacitance is prioritized over strict 10 V clamping ceiling. |
| uClamp0501ZATFT | Clamps at 8.5 V (IPP = 12 A); 0.65 pF capacitance; DFN-6 (1.0 × 0.6 mm) package. | Lower surge rating (12 A vs. 24 A) reduces robustness against IEC 61000-4-5 indirect lightning surges. | Select when system-level surge testing is limited to IEC 61000-4-2/4-4 only and board space allows no trade-off on peak current. |
Compared with RClamp0524P.TCT and uClamp0501ZATFT, PCLAMP0511ZVTFT uniquely balances 9.5 V clamping, 24 A surge capability, and 0.55 pF capacitance in a standardized DFN-6 footprint - making it optimal for USB 2.0, HDMI, and industrial 5V I/O where both signal fidelity and high-energy transient resilience are required.

FAQ
What is the maximum clamping voltage of PCLAMP0511ZVTFT at 24A surge current?
PCLAMP0511ZVTFT clamps at 9.5 V when subjected to a 24A peak pulse current (8/20 μs waveform). This value is guaranteed across −40°C to +125°C and remains stable due to its FET-based architecture - unlike conventional TVS diodes whose clamping rises linearly with current. The 9.5 V ceiling ensures safe operation with 5V logic families.
Does PCLAMP0511ZVTFT require a thermal pad on the PCB?
No, PCLAMP0511ZVTFT does not require a thermal pad. Its energy dissipation occurs primarily through conduction via the six external terminals (three GND and three IN), not through the package bottom. The datasheet explicitly states "no thermal pad is needed," and layout guidelines emphasize low-inductance grounding of all six pins instead.
Can PCLAMP0511ZVTFT be used on bidirectional data lines like USB DP/DM?
Yes, PCLAMP0511ZVTFT is fully bidirectional and rated for use on USB 2.0 DP/DM lines. Its symmetrical structure (identical forward/reverse characteristics) and 0.55 pF capacitance ensure minimal impact on differential signal integrity while providing ±30 kV ESD protection per IEC 61000-4-2 - confirmed in Semtech's application notes for USB interface protection.
What is the leakage current specification for PCLAMP0511ZVTFT at 5V operating voltage?
At VRWM = 5 V and TA = 25°C, PCLAMP0511ZVTFT exhibits a maximum reverse leakage current of 100 nA. This low leakage preserves signal rail stability and avoids unintended current draw in battery-powered USB peripherals or always-on HDMI CEC receivers.
Is PCLAMP0511ZVTFT compatible with lead-free reflow profiles?
Yes, PCLAMP0511ZVTFT is qualified for standard lead-free reflow soldering per JEDEC J-STD-020. Its DFN-6 package uses matte tin (Sn) lead finish and withstands peak temperatures up to 260°C for 30 seconds - fully compliant with IPC-A-610 Class 2 and Class 3 assembly requirements.
