Product details
Overview
RCLAMP0502N.TCT from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection of single 5V I/O or power lines in USB, industrial, and IoT interfaces. It delivers ±30kV IEC 61000-4-2 ESD immunity, clamps at 7.5V (IPP = 24A), maintains <20mΩ dynamic resistance, and operates from –40°C to +125°C in a 1.6 × 1.6 mm DFN-6 package.
For engineers reviewing the RCLAMP0502N.TCT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability across temperature and peak pulse current, low junction capacitance (12pF), and compatibility with USB 2.0, HDMI, and industrial control signal lines requiring robust 5V-level surge suppression.
Technical Context
RCLAMP0502N.TCT uses a surge-rated FET as its primary protection element, activated by an integrated precision trigger circuit that initiates shunting when transient voltage exceeds breakdown threshold. Unlike conventional TVS diodes, its clamping voltage remains nearly constant (7.5V typical) from 1A to 24A (8/20μs) due to decreasing RDS(on) under surge conditions.
The device protects one bidirectional line with 5V working voltage (VRWM = 5V), features 12pF junction capacitance at 0V bias, and exhibits <100nA reverse leakage at VRWM. Its DFN-6 layout assigns pins 1–3 to GND and pins 4–6 to IN, requiring all three GND and all three IN pins to be connected for full 24A surge rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 5V - Matches standard USB 2.0, HDMI, and industrial 5V logic signal rails without derating. |
| Clamping Voltage (IPP = 24A) | 7.5V - Keeps protected ICs (e.g., USB transceivers) safely below absolute maximum ratings during 8/20μs surges. |
| ESD Withstand | ±30kV contact/air (IEC 61000-4-2) - Eliminates need for secondary ESD stages in handheld and connector-facing designs. |
| Junction Capacitance | 12pF @ 0V - Enables use on 480 Mbps USB 2.0 data lines without signal integrity degradation. |
| Dynamic Resistance | 18mΩ - Ensures minimal voltage rise under high di/dt transients, critical for fast-rising EFT and lightning surges. |
| Peak Pulse Current | 24A (8/20μs) - Meets IEC 61000-4-5 Level 3 (±1kV, 42Ω source) for industrial equipment input protection. |
| Operating Temperature | –40°C to +125°C - Supports deployment in automotive cabin modules, industrial PLCs, and outdoor IoT gateways. |
Pinout & Package
Package: DFN-6, 1.6 mm × 1.6 mm × 0.55 mm, RoHS-compliant, halogen-free, UL 94V-0 molding compound. Exposed thermal pad not required; energy dissipated via silicon FET channel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected to minimize inductance and achieve full 24A rating. |
| Pins 4, 5, 6 | IN | Protected line input (bidirectional); all three pins tied together at PCB trace to distribute surge current and reduce localized heating. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based transient shunting | Enables flat clamping voltage (7.5V ±0.5V) across 1–24A surge range-unlike TVS diodes whose VC rises linearly with IPP. |
| Low 12pF capacitance | Preserves signal integrity on high-speed 480 Mbps USB 2.0 differential pairs without added termination or equalization. |
| ±30kV ESD immunity | Meets IEC 61000-4-2 Level 4 without external shielding or layout guard rings-reducing BOM count and board area. |
| Stable clamping over temperature | VC varies <0.3V from –40°C to +125°C at 24A, enabling reliable protection in uncontrolled thermal environments. |
| DFN-6 footprint | 1.6 × 1.6 mm size saves >60% board space vs. legacy SOT-23 TVS solutions while supporting automated reflow assembly. |
Applications
| USB 2.0 Data Lines | HDMI DDC/CEC Channels |
|---|---|
|
Use Scenario: Protecting D+ and D− lines of USB 2.0 ports against ESD events from hot-plug insertion and cable handling. IC Role / Device Role / Timing Role: Bidirectional transient suppressor placed immediately after the USB connector, before the USB transceiver IC. Use Value: 12pF capacitance avoids eye diagram distortion at 480 Mbps; 7.5V clamping prevents latch-up in PHY receivers rated for 3.6V max VIH. |
Use Scenario: Securing HDMI DDC (I²C) and CEC control lines against ESD during AV receiver or display port connection. IC Role / Device Role / Timing Role: Low-capacitance shunt protector on 5V-tolerant I²C bus lines operating up to 400 kHz. Use Value: Sub-100nA leakage at 5V ensures no pull-up current loss; ±30kV ESD rating eliminates system resets during field service. |
| Industrial Sensor Inputs | POS Terminal Interfaces |
|
Use Scenario: Shielding analog or digital sensor inputs (e.g., 4–20mA loop receivers, RS-485 stubs) from lightning-induced surges in factory automation. IC Role / Device Role / Timing Role: Primary front-end surge diverter on 5V-supplied sensor interface nodes exposed to harsh EMI environments. Use Value: 24A peak pulse rating meets IEC 61000-4-5 Level 3; stable 7.5V clamping prevents damage to precision ADC front-ends. |
Use Scenario: Hardening payment terminal USB-C or micro-USB ports against customer-handled ESD and accidental 12V misconnection. IC Role / Device Role / Timing Role: Input-stage protector on 5V VBUS or CC line, co-located with uClamp2411ZA for multi-voltage coverage. Use Value: DFN-6 footprint enables dense port-side placement; RoHS/REACH compliance supports global retail certification requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Standard unidirectional TVS diode; 9.2V clamping at 24A; 100pF capacitance; SMC package (7.1 × 6.2 mm). | Higher clamping voltage risks PHY damage; excessive capacitance degrades USB 2.0 signal integrity; unsuitable for high-density layouts. | Select only if cost is primary constraint and signal speed ≤12 Mbps; requires PCB redesign for larger footprint. |
| TPD4E004DRYR | Quad-channel 5V TVS array; 12pF/channel; 12V clamping at 1A; 4A max per channel; X2SON-8 package. | Limited to 4A per line-insufficient for IEC 61000-4-5 compliance; clamping rises sharply above 1A; not rated for 24A surges. | Use only for ESD-only (IEC 61000-4-2) protection on low-current control lines-not for combined ESD/EFT/surge environments. |
Compared with SMAJ5.0A and TPD4E004DRYR, RCLAMP0502N.TCT uniquely combines 24A surge capability, 7.5V flat clamping, and 12pF capacitance in a 1.6 mm² footprint-making it the only option qualified for USB 2.0 data line protection meeting both IEC 61000-4-2 and -4-5 standards simultaneously.

FAQ
What is the maximum peak pulse current rating for RCLAMP0502N.TCT?
RCLAMP0502N.TCT is rated for 24A peak pulse current under IEC 61000-4-5 8/20μs waveform conditions. This rating assumes all three IN pins (4–6) and all three GND pins (1–3) are properly connected on the PCB to ensure current sharing and thermal distribution. The device maintains 7.5V clamping at this level, verified across –40°C to +125°C.
Does RCLAMP0502N.TCT support bidirectional signal lines like USB D+ and D−?
Yes, RCLAMP0502N.TCT is inherently bidirectional and symmetric-its internal FET-based architecture provides identical clamping performance for positive and negative transients. It is explicitly validated for USB 2.0 D+ and D− line protection in Semtech's application notes, with 12pF capacitance ensuring minimal impact on 480 Mbps data eye diagrams.
How does RCLAMP0502N.TCT differ from traditional TVS diodes in clamping behavior?
Unlike PN-junction TVS diodes whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN), RCLAMP0502N.TCT uses a triggered FET to maintain near-constant 7.5V clamping from 1A to 24A. Its dynamic resistance drops to ~18mΩ under surge, eliminating the trade-off between surge rating and safe clamping voltage seen in conventional TVS devices.
Can RCLAMP0502N.TCT replace a standard 5V TVS diode in an existing design without layout changes?
No-RCLAMP0502N.TCT requires connection of all six pins: pins 1–3 to solid ground plane and pins 4–6 to the protected line. Its DFN-6 1.6 × 1.6 mm footprint differs from common SOD-323 or SOT-23 packages. Layout must include short, wide traces and multiple vias to ground to achieve full 24A rating; direct drop-in replacement is not supported.
Is RCLAMP0502N.TCT compliant with environmental and safety standards?
Yes, RCLAMP0502N.TCT is RoHS-compliant, halogen-free, and certified to UL 94V-0 for flammability. It meets IEC 61000-4-2 (±30kV ESD), IEC 61000-4-4 (±4kV EFT), and IEC 61000-4-5 (24A surge) standards. Semtech's datasheet confirms full qualification across –40°C to +125°C ambient operation with no derating required.
