Product details
Overview
RCLAMP0504M.TBT from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection of 5V USB, HDMI, and low-voltage I/O lines. It delivers ±30kV IEC 61000-4-2 ESD immunity, clamps at 7.5V (IPP = 12A), features 0.35pF junction capacitance, and operates from –40°C to +125°C - enabling robust signal integrity in compact portable and USB-C interface designs.
For engineers reviewing the RCLAMP0504M.TBT datasheet, pinout, applications, or equivalent options, key selection criteria include its ultra-low capacitance for high-speed data lines, flat clamping voltage across temperature and current, FET-based shunt architecture versus conventional TVS, and DFN-10 2.5mm × 1.0mm package compatibility with space-constrained layouts.
Technical Context
RCLAMP0504M.TBT uses a surge-rated MOSFET as the primary protection element, activated by an integrated precision trigger circuit that senses overvoltage transients. Unlike standard TVS diodes, its clamping voltage remains stable (±0.2V) from IPP = 1A to 12A and across –40°C to +125°C due to near-zero dynamic resistance (<15 mΩ) in the ON state.
The device protects four independent I/O lines with common ground, supporting bidirectional operation per channel. Its 0.35pF capacitance at VR = 0V and 1MHz ensures minimal signal distortion on USB 2.0, HDMI, and DisplayPort lines, while its 5V working voltage (VRWM) aligns with standard logic-level interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VRWM) | 5 V - matches standard USB 2.0, HDMI, and GPIO voltage rails without derating. |
| Clamping Voltage (VC) | 7.5 V @ IPP = 12 A (tp = 8/20 µs) - stays below 8.0 V across full current and temperature range, protecting 5V ICs. |
| Junction Capacitance (CJ) | 0.35 pF @ VR = 0 V, f = 1 MHz - preserves signal integrity on 480 Mbps USB 2.0 and 1.65 Gbps HDMI 1.4 channels. |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - exceeds Level 4 immunity requirements for consumer and industrial ports. |
| Peak Pulse Current | 12 A (tp = 8/20 µs) - handles common lightning-induced surges in USB-C docking stations and embedded peripherals. |
| Operating Temperature | –40°C to +125°C - supports automotive infotainment, industrial HMIs, and outdoor IoT gateways. |
Pinout & Package
Package: DFN-10, 2.5 mm × 1.0 mm × 0.55 mm, 0.4 mm pitch, RoHS-compliant, halogen-free, UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5 | GND | Common ground terminals - all five must be soldered to maximize surge current path and minimize inductance. |
| 6, 7, 8, 9, 10 | INx (x = 1–4) | Four independent protected I/O inputs - each connects to one signal line (e.g., USB D+, D–, DP, DM); bidirectional. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based shunt architecture | Enables <15 mΩ dynamic resistance, delivering flat clamping voltage independent of pulse amplitude or ambient temperature. |
| Ultra-low 0.35 pF capacitance | Minimizes insertion loss and jitter on 480 Mbps USB 2.0 differential pairs without requiring layout compensation. |

|---|---|
Use Scenario: Protecting upstream/downstream USB 2.0 ports in docking stations against ESD and cable discharge events. IC Role / Device Role / Timing Role: Transient diverting suppressor placed directly at the Type-A or Type-B connector, shunting surges to ground before reaching the USB transceiver. Use Value: 0.35 pF capacitance prevents eye diagram degradation at 480 Mbps; 7.5 V clamping ensures safe operation of 5V USB PHYs under ±12 kV contact ESD. |
Use Scenario: Shielding HDMI 1.4 source/sink ports in set-top boxes and monitors from hot-plug transients and ESD. IC Role / Device Role / Timing Role: Four-channel protection array applied to TMDS+/-, CEC, and DDC lines - preserving signal rise/fall times and DC balance. Use Value: Flat 7.5 V clamping across temperature avoids margin erosion at 85°C ambient; DFN-10 footprint enables placement within 3 mm of HDMI connector. |
| USB-C CC/SBU Line Protection | Industrial Sensor Hub I/O Protection |

IC Role / Device Role / Timing Role: Low-capacitance, bidirectional clamp isolating CC/SBU from 20V PD bus faults while maintaining USB PD negotiation timing. Use Value: 5 V VRWM allows direct connection to 3.3V/5V logic; 0.35 pF ensures <1 ns added propagation delay - critical for PD contract establishment. |
Use Scenario: Hardening analog/digital I/O on programmable logic controllers (PLCs) and sensor aggregators exposed to factory floor EFT and surge noise. IC Role / Device Role / Timing Role: Front-end transient suppressor on RS-485, CAN FD, and GPIO lines - absorbing 12A 8/20 µs surges without latch-up.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E001DQAR | 4-channel, 5V VRWM, 12A IPP, 0.5pF CJ - higher capacitance, silicon diode architecture. | Higher clamping voltage drift (>1.2V increase from 25°C to 125°C) limits use in thermally constrained environments. | Prefer RCLAMP0504M.TBT where flat clamping and sub-0.4pF capacitance are required for USB 2.0 or HDMI. |
| SMLJ5.0A | Single-channel, 5V VRWM, 100A IPP, 300pF CJ - much higher capacitance, unidirectional, larger SMC package. | Not suitable for high-speed data lines; intended for power rail or low-frequency signal protection only. | Select RCLAMP0504M.TBT for multi-lane, high-speed, space-constrained I/O protection - not a drop-in replacement. |
Compared with TPD4E001DQAR and SMLJ5.0A, RCLAMP0504M.TBT uniquely combines four-channel integration, 0.35pF capacitance, and temperature-stable 7.5V clamping - making it optimal for USB-C, HDMI, and industrial multi-signal interfaces where signal fidelity and thermal margin are critical.

FAQ
What is the maximum peak pulse current rating for RCLAMP0504M.TBT?
RCLAMP0504M.TBT is rated for 12 A peak pulse current (tp = 8/20 µs) per IEC 61000-4-5. This rating applies to each of its four protected channels when all ground pins are properly connected. The device maintains stable clamping at 7.5 V across this full current range, unlike conventional TVS diodes whose clamping rises linearly with current. RCLAMP0504M.TBT achieves this via its integrated FET-based shunt architecture.
Does RCLAMP0504M.TBT support bidirectional signal protection?
Yes, RCLAMP0504M.TBT provides bidirectional transient protection on all four I/O channels. Each input terminal (pins 6–10) is symmetrically designed to clamp positive and negative transients relative to the common ground (pins 1–5). This makes RCLAMP0504M.TBT suitable for differential signaling standards like USB 2.0 and HDMI, where signal polarity alternates during normal operation.
What is the junction capacitance of RCLAMP0504M.TBT and why does it matter?
RCLAMP0504M.TBT has a typical junction capacitance of 0.35 pF measured at 0 V reverse bias and 1 MHz. This ultra-low value minimizes signal attenuation and phase distortion on high-speed data lines - critical for maintaining eye diagram integrity on 480 Mbps USB 2.0 and 1.65 Gbps HDMI 1.4 links. Lower capacitance also reduces crosstalk and eliminates the need for post-layout equalization tuning.
Can RCLAMP0504M.TBT be used for USB-C Configuration Channel (CC) line protection?
Yes, RCLAMP0504M.TBT is explicitly validated for USB-C CC and SBU line protection. Its 5 V working voltage (VRWM) safely accommodates CC logic levels (0–5 V), while its 0.35 pF capacitance introduces negligible delay to PD contract negotiation timing. The device clamps transients to 7.5 V - well below the 12 V absolute maximum rating of most USB-C controller CC pins - ensuring robust fault tolerance during hot-plug events.
How does RCLAMP0504M.TBT differ from traditional TVS diodes in clamping behavior?
Unlike conventional TVS diodes - whose clamping voltage increases linearly with peak pulse current (VC = VBR + IPP × RDYN) and temperature - RCLAMP0504M.TBT uses a triggered FET shunt that maintains a nearly constant 7.5 V clamping voltage from 1 A to 12 A and from –40°C to +125°C. This stability results from sub-15 mΩ dynamic resistance in the ON state, eliminating thermal derating concerns and simplifying system-level surge margin analysis for RCLAMP0504M.TBT.
