Product details
Overview
RCLAMP0582N.TCT from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS/ESD protection of 22V-rated power or I/O lines. It delivers ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), and stable 27.5–28V clamping across full temperature (−40°C to +125°C) and current range - critical for USB PD and industrial load switch input protection.
For engineers reviewing the RCLAMP0582N.TCT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under surge, low dynamic resistance (<20 mΩ), junction capacitance (175 pF at 22V), and DFN 1.6×1.6mm 6-lead package compatibility with high-density USB Type-C and IoT layouts.
Technical Context
RCLAMP0582N.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. Unlike conventional TVS diodes, its clamping voltage remains nearly constant (27.5–28V) from 24A to 40A due to decreasing RDS(on), not fixed dynamic resistance.
The device protects one bidirectional line with 22V reverse stand-off voltage (VRWM), 25–27.9V breakdown (VBR), and 130–600 nA leakage at VRWM. Its functional architecture enables robust protection against IEC 61000-4-5 surges (±1kV, 1.2/50μs + 8/20μs combo wave) and IEC 61000-4-4 EFT (±4kV).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-Off Voltage | 22 V - maximum continuous operating voltage before clamping activation |
| Clamping Voltage | 27.5–28 V at 40A (8/20μs) - ensures protected ICs (e.g., USB PD controllers) remain below damage threshold |

| Temperature-stable clamping | Clamping voltage varies <±0.5 V from −40°C to +125°C - enables reliable protection without derating |
| High-energy surge rating | 1120 W peak pulse power (8/20μs) - sustains repeated 40A transients without degradation |
| Low-leakage protection | 600 nA max reverse leakage at 22 V - avoids loading sensitive 22V supply rails during normal operation |
| Compact DFN footprint | 1.6×1.6 mm area - saves >50% board space vs. SO-8 or SOT-23 TVS alternatives for equivalent surge rating |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting VBus lines in USB-C receptacles supporting up to 20V/5A PD negotiation, exposed to ESD and lightning-induced surges. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed directly at connector, clamping transients before they reach PD controller or load switch. Use Value: Maintains 27.5–28V clamping across temperature and current - prevents overvoltage damage to 22V-tolerant PD ICs where conventional TVS would exceed safe limits at high TA. |
Use Scenario: Safeguarding input terminals of industrial-grade load switches (e.g., HS2950P) in remote meters, robotics, and factory automation equipment. IC Role / Device Role / Timing Role: Front-end surge diverter that absorbs IEC 61000-4-5 surges before they stress the internal FET gate oxide or drain-source junction. Use Value: Limits clamping voltage to ≤28V - stays well below typical 30–36V absolute maximum ratings of industrial load switches, extending reliability under repeated surge events. |
| IoT Edge Device Power Bus Protection | Storage Device 22V Rail Protection |
Use Scenario: Securing 22V auxiliary power rails in battery-backed smart sensors, gateways, and edge AI modules deployed in uncontrolled environments. IC Role / Device Role / Timing Role: Single-device solution for combined ESD, EFT, and surge protection on non-data-critical power paths. Use Value: Delivers ±4kV EFT immunity (IEC 61000-4-4) and ±30kV ESD without requiring cascaded protection stages - simplifies BOM and layout. |
Use Scenario: Protecting 22V backup or auxiliary supplies in NVMe SSD enclosures, enterprise HDD backplanes, and RAID controllers. IC Role / Device Role / Timing Role: High-energy transient suppressor on storage subsystem power inputs, guarding against hot-plug transients and system-level coupling. Use Value: 40A surge capability handles worst-case inrush and fault currents - avoids latch-up or catastrophic failure during field-replaceable module insertion. |
Equivalent & Alternatives

FAQ
What is the maximum continuous operating voltage for RCLAMP0582N.TCT?
The RCLAMP0582N.TCT has a reverse stand-off voltage (VRWM) of 22 V, meaning it can continuously withstand up to 22 V on the protected line without activating clamping. This makes RCLAMP0582N.TCT ideal for 20V USB PD VBus and other 22V-rated industrial power rails where stable, non-conductive standby behavior is required.
How does RCLAMP0582N.TCT achieve stable clamping voltage across temperature and current?
RCLAMP0582N.TCT uses a surge-rated FET as its main protection element, triggered by an internal precision circuit. As surge current increases, the FET's RDS(on) decreases, maintaining clamping voltage near the trigger circuit's breakdown level - resulting in 27.5–28 V across −40°C to +125°C and 24–40A. This behavior is fundamentally different from TVS diodes and is confirmed in RCLAMP0582N.TCT's datasheet Figures 3 and 4.
Can RCLAMP0582N.TCT replace standard TVS diodes in 22V applications?
Yes - RCLAMP0582N.TCT is explicitly designed as a superior replacement for conventional TVS diodes in 22V systems. Its flat clamping curve, 40A surge rating, and temperature stability eliminate the need to overspecify TVS devices to compensate for VC drift. RCLAMP0582N.TCT has been validated in Semtech reference designs for USB-C and load switch protection where standard TVS solutions failed thermal or voltage margin checks.
What is the recommended PCB layout for RCLAMP0582N.TCT?
Place RCLAMP0582N.TCT 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 thermal pads - energy is dissipated internally. This layout minimizes parasitic inductance and ensures RCLAMP0582N.TCT delivers its rated 40A surge performance.
Is RCLAMP0582N.TCT RoHS and halogen-free compliant?
Yes - RCLAMP0582N.TCT is fully RoHS and WEEE compliant, lead-free, and halogen-free. Its molding compound meets UL 94V-0 flammability rating, and the lead finish is matte tin. These compliance attributes are documented in the official Semtech datasheet for RCLAMP0582N.TCT and verified through material declarations.
