Product details
Overview
RCLAMP0584J.TCT from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS/ESD protection of 22V-rated power or I/O lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 40A, and ultra-low 20mΩ dynamic resistance - deployed in USB Type-C PD input protection and industrial load switch front-end circuits.
For engineers reviewing the RCLAMP0584J.TCT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature and current, low capacitance (175pF @ 22V), DFN 1.6×1.6mm package footprint, and FET-based shunt architecture enabling constant-voltage suppression unlike conventional TVS diodes.
Technical Context
RCLAMP0584J.TCT uses a surge-rated MOSFET as its primary protection element, activated by a precision trigger circuit that turns on the shunt path when transient voltage exceeds breakdown. Its clamping voltage remains nearly constant (27.5–28V) from 24A to 40A due to decreasing RDS(on), not fixed dynamic resistance.
The device operates over –40°C to +125°C with reverse stand-off voltage of 22V, breakdown voltage of 25–27.9V, and reverse leakage ≤600nA at 22V. It meets IEC 61000-4-2 (±30kV), IEC 61000-4-4 (±4kV EFT), and IEC 61000-4-5 (±1kV unsymmetrical, 42Ω source).
Key Specifications

IC Role / Device Role / Timing Role: High-energy shunt protector that diverts surge energy away from the load switch's internal FET drain-source junction. Use Value: Prevents latch-up or gate oxide rupture in the load switch by limiting transient voltage to ≤28V - critical where switch VDSS margin is tight (e.g., 30V-rated devices). |
| IoT Edge Device Power Bus Protection | Storage Device 22V Rail Protection |
|
Use Scenario: Securing 22V auxiliary power inputs in battery-backed edge nodes subjected to field ESD and induced surges during docking or cable hot-plug. IC Role / Device Role / Timing Role: Standalone EOS suppressor on main power entry point, coordinating with downstream low-capacitance TVS for data lines. Use Value: Delivers 40A surge handling in <2.56 mm² footprint - enables ruggedized, space-constrained designs without sacrificing reliability. |
Use Scenario: Protecting 22V supply rails in NVMe SSD enclosures and enterprise storage backplanes exposed to system-level surges during hot-swap events. IC Role / Device Role / Timing Role: High-power transient clamp on primary power distribution node upstream of PMIC and voltage regulators. Use Value: 1120W peak pulse power rating (8/20μs) sustains multi-millisecond surges without degradation - extends system MTBF in mission-critical storage infrastructure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P.C | Same die, identical electrical specs, same DFN 1.6×1.6mm package; differs only in tape-and-reel packaging (3,000 pcs/reel vs. 10,000 for RCLAMP0584J.TCT). | Identical use cases - USB-C PD, load switch, industrial 22V rail protection - with no layout or performance trade-offs. | Select TDS2211P.C for smaller batch procurement or qualification alignment with Semtech's standard part numbering. |
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.5V VC @ 22.5A; higher clamping (+7.5V), no temperature stability, 1.5× larger SMC package. | Suitable only for lower-energy, non-temperature-critical applications; cannot replace RCLAMP0584J.TCT in USB PD or high-temp industrial use without redesign. | Consider SMAJ22A only if cost is primary constraint and clamping voltage margin >35V is acceptable - requires revalidation of protected IC survival. |
Compared with TDS2211P.C, RCLAMP0584J.TCT offers identical protection performance with optimized logistics packaging; compared with SMAJ22A, RCLAMP0584J.TCT delivers 7.5V lower clamping, stable performance across temperature, and 60% smaller footprint - making it essential for modern 22V high-reliability interfaces.

FAQ
What is the clamping voltage behavior of RCLAMP0584J.TCT under varying surge current?
RCLAMP0584J.TCT maintains a tightly regulated clamping voltage of 27.5–28V across its full rated peak pulse current range (24A to 40A, 8/20μs + 1.2/50μs combo waveform), thanks to its FET-based shunt architecture and sub-20mΩ dynamic resistance. Unlike TVS diodes, this clamping does not increase with current - a key advantage for protecting voltage-sensitive ICs like USB PD controllers where margin is narrow. The RCLAMP0584J.TCT datasheet confirms this flat response in Figure 3 and Table 2.
How does RCLAMP0584J.TCT differ from standard TVS diodes in temperature performance?
RCLAMP0584J.TCT exhibits stable clamping voltage (27.5–28V) from –40°C to +125°C, whereas conventional TVS diodes show significant clamping voltage rise with temperature due to positive temperature coefficient of dynamic resistance. This makes RCLAMP0584J.TCT uniquely suited for automotive-adjacent industrial applications and enclosed IoT devices where ambient temperature can exceed 85°C. The RCLAMP0584J.TCT functional diagram and Figure 4 in its datasheet validate this thermal stability.
Can RCLAMP0584J.TCT be used on USB-C superspeed differential pairs?
No - RCLAMP0584J.TCT is not suitable for USB-C superspeed (TX/RX) or DisplayPort lines due to its 175pF junction capacitance, which would severely degrade signal integrity. It is designed exclusively for 22V single-ended power or control lines (e.g., VBUS, CC, SBU). For superspeed protection, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF). The RCLAMP0584J.TCT application note explicitly restricts its use to power-rail-level protection, not high-speed data lanes.
What is the recommended PCB layout for optimal surge performance of RCLAMP0584J.TCT?
For optimal performance, place RCLAMP0584J.TCT within 2 mm of 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 ≥3 vias. Avoid thermal relief on GND pads. This minimizes parasitic inductance and ensures full 40A surge current sharing. The RCLAMP0584J.TCT datasheet Figure 7 provides the exact land pattern and layout guidance.
Is RCLAMP0584J.TCT compatible with lead-free reflow processes?
Yes - RCLAMP0584J.TCT is fully compatible with standard lead-free reflow profiles (JEDEC J-STD-020), including peak temperatures up to 260°C. Its DFN package uses lead-free terminal finish and UL 94V-0 molding compound, meeting IPC-A-610 Class 2/3 requirements. The RCLAMP0584J.TCT packaging specification confirms Pb-free compliance and outlines moisture sensitivity level (MSL) 1 handling instructions.
