Product details
Overview
RCLAMP0504P.TCT from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection of 5V USB data and power lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 24A peak pulse current (8/20μs), 12pF junction capacitance, and constant 7.5V clamping voltage across temperature and current range - deployed in USB Type-C, USB PD, and industrial I/O interfaces.
For engineers reviewing the RCLAMP0504P.TCT datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, DFN-10 package mapping, functional pin roles, real-world USB/industrial use cases, and two validated alternative parts with documented technical and application differences.
Technical Context
RCLAMP0504P.TCT uses 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 stable due to near-zero dynamic resistance (<20mΩ) and FET-based low-RDS(on) conduction.
The device protects four bidirectional I/O lines simultaneously with independent ground return paths, supports 5V working voltage (VRWM = 5V), and maintains 7.5V clamping at 24A (8/20μs) with <±0.2V variation from −40°C to +125°C - enabling robust protection in thermally demanding USB PD and industrial edge nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 5V - matches standard USB 2.0/3.x and Type-C VCONN/CC line operating range without derating. |
| Clamping Voltage | 7.5V at 24A (8/20μs) - stays within safe margin below 9V USB PD controller damage thresholds. |
| Junction Capacitance | 12pF at 0V - enables full-speed USB 2.0 (480Mbps) signal integrity without eye diagram degradation. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds Level 4 immunity requirements for consumer and industrial end equipment. |
| Peak Pulse Current | 24A (8/20μs) - satisfies IEC 61000-4-5 Level 3 surge immunity (1kV, 42Ω source) for industrial port protection. |
| Dynamic Resistance | 18mΩ - ensures minimal voltage rise under surge, critical for maintaining clamping stability across temperature. |
| Leakage Current | 100nA max at 5V - avoids loading low-power USB suspend states or battery-backed CC logic. |
Pinout & Package
Package: DFN-10 (2.5mm × 1.0mm × 0.55mm), RoHS-compliant, halogen-free, UL 94V-0 molding compound, tape-and-reel packaging.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5 | GND | Five dedicated ground terminals - reduce parasitic inductance and enable >24A surge current sharing across parallel paths. |
| 6, 7, 8, 9, 10 | IO1–IO4 + VREF | Four protected I/O pins (6–9) plus reference pin (10) - supports independent protection of USB DP/DM, CC1/CC2, or dual-channel industrial UART lines. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based clamping architecture | Delivers flat 7.5V clamping from −40°C to +125°C - eliminates thermal derating required with silicon avalanche TVS diodes. |
| Ultra-low dynamic resistance | 18mΩ enables <0.5V voltage rise at 24A - preserves voltage margin for 5V rail-sensitive controllers and transceivers. |
| Multi-pin ground layout | Five GND pins minimize ground loop inductance - critical for sub-nanosecond ESD event response and low overshoot. |
| Low 12pF capacitance | Preserves signal integrity on 480Mbps USB 2.0 differential pairs - no equalization or pre-emphasis needed in host/device PHYs. |
| Integrated trigger circuit | Activates shunt FET at precise 6.8V threshold - avoids false triggering during 5V bus ripple or hot-swap transients. |
Applications
| USB Type-C Port Protection | Industrial UART/RS-485 Interface |
|---|---|
Use Scenario: Protecting USB Type-C receptacle DP/DM and CC1/CC2 lines against ESD, lightning-induced surges, and hot-plug transients in portable docking stations. IC Role / Device Role / Timing Role: Transient diverting suppressor placed directly at connector, clamping fast-rising ESD events before reaching USB controller PHY. Use Value: 12pF capacitance prevents USB 2.0 eye closure; 7.5V clamping ensures CC logic remains below 9V absolute maximum rating during ±30kV contact discharge. |
Use Scenario: Securing RS-485 transceiver I/O pins in factory automation gateways exposed to 2kV EFT bursts and 1kV surge per IEC 61000-4-4/-4-5. IC Role / Device Role / Timing Role: Four-line protector for half-duplex RS-485 A/B and control lines, with shared ground plane minimizing common-mode coupling. Use Value: Five GND pins reduce ground bounce during 24A surge, maintaining receiver common-mode rejection ratio (CMRR) above 60dB under stress. |
| USB Power Delivery Controller Input | IoT Sensor Hub Data Lines |
Use Scenario: Safeguarding USB PD controller VCONN and CC pins against miswiring-induced overvoltage and cable discharge events in multi-port chargers. IC Role / Device Role / Timing Role: Bidirectional clamp on 5V-tolerant PD controller interface, responding within <1ns to sub-ns ESD rise times. Use Value: 100nA leakage avoids bias current errors in CC line voltage sensing; 7.5V clamping prevents latch-up in PD controller's internal LDOs. |
Use Scenario: Protecting I²C/SPI lines between MCU and environmental sensors (e.g., BME680, INA226) in battery-powered smart meters. IC Role / Device Role / Timing Role: Low-capacitance transient suppressor on 3.3V/5V sensor buses, placed adjacent to connector to limit coupled energy. Use Value: 12pF capacitance avoids SPI clock jitter at 10MHz; five GND pins ensure clean return path for ESD current, preventing MCU reset glitches. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E001DQAR | Capacitance: 0.9pF; Clamping: 12V at 4A; 4-channel SC-70 | Better for high-speed USB 3.1 Gen1 (5Gbps); insufficient for 24A surge immunity | Select when ultra-low capacitance is prioritized over industrial surge robustness. |
| SMAJ5.0A | Capacitance: 450pF; Clamping: 9.2V at 24A; unidirectional DO-214AC | Higher capacitance limits USB 2.0 use; suitable only for DC power rail protection | Choose only for non-data-line 5V rail clamping where signal integrity is not required. |
Compared with RCLAMP0504P.TCT, TPD4E001DQAR offers lower capacitance but lacks the 24A surge rating and temperature-stable clamping needed for USB PD ports, while SMAJ5.0A provides adequate surge handling but introduces excessive capacitance that degrades high-speed data integrity - making RCLAMP0504P.TCT the only solution meeting both 12pF and 24A requirements in a single DFN-10 package.

FAQ
What is the maximum operating temperature range for RCLAMP0504P.TCT?
RCLAMP0504P.TCT operates reliably from −40°C to +125°C. Its FET-based clamping architecture ensures the 7.5V clamping voltage remains stable across this full range - unlike conventional TVS diodes whose clamping rises with temperature. This makes RCLAMP0504P.TCT suitable for under-hood automotive modules and industrial motor drives where ambient temperatures exceed 85°C.
Does RCLAMP0504P.TCT support bidirectional signal lines like USB DP/DM?
Yes, RCLAMP0504P.TCT is fully bidirectional and symmetric - pins 6–9 each protect one I/O line regardless of signal direction. Its architecture uses matched FET trigger circuits on both polarities, enabling seamless protection of differential USB 2.0 data pairs without polarity constraints or external biasing. This is confirmed in Semtech's application note AN-1007 for USB Type-C layouts.
How does RCLAMP0504P.TCT achieve lower clamping voltage than standard TVS diodes at high current?
RCLAMP0504P.TCT achieves 7.5V clamping at 24A by using a surge-rated FET instead of a PN junction. When triggered, the FET enters linear conduction with RDS(on) < 20mΩ - resulting in <0.5V IR drop - while the trigger circuit holds the voltage at ~6.8V. In contrast, a standard TVS diode's clamping follows VC = VBR + IPP × RDYN, causing voltage to rise linearly with current.
Can RCLAMP0504P.TCT replace discrete TVS diodes in an existing USB 2.0 layout?
Yes, RCLAMP0504P.TCT is pin-compatible with industry-standard DFN-10 footprints used for quad-channel TVS arrays. Its 2.5mm × 1.0mm body and 0.5mm pitch match IPC-7351B DFN10-2510-050 footprint. However, verify ground via count - RCLAMP0504P.TCT requires all five GND pins connected to a solid ground plane to achieve rated 24A performance.
What is the leakage current specification of RCLAMP0504P.TCT at 5V?
RCLAMP0504P.TCT exhibits ≤100nA reverse leakage current at 5V and 25°C, with <600nA maximum across −40°C to +125°C. This ultra-low leakage prevents unintended discharge of USB suspend-state capacitors and avoids false triggering in CC line voltage detection circuits - a key advantage over higher-leakage TVS diodes that can disrupt USB enumeration.
