Product details
Overview
RCLAMP0524P.TCT from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection of 22V-rated I/O or power lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 40A, 20mΩ dynamic resistance, and 175pF junction capacitance - deployed in USB Type-C PD input protection and industrial load switch inputs.
For engineers reviewing the RCLAMP0524P.TCT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature and current, low dynamic resistance for flat VC vs. IPP behavior, DFN-6 package layout constraints, and compatibility with 22V bus systems requiring robust surge immunity per IEC 61000-4-5.
Technical Context
RCLAMP0524P.TCT implements a surge-rated FET as its primary protection element, activated by a precision trigger circuit that turns on the shunt FET when transient voltage exceeds breakdown threshold. Unlike conventional TVS diodes, its clamping voltage remains nearly constant over 24–40A (8/20μs) due to decreasing RDS(on) under surge conditions.
The device operates across −40°C to +125°C with stable 27.5–28V clamping at rated current and maintains <600nA reverse leakage at 22V VRWM. Its functional architecture separates trigger sensing (VBR ≈ 27.9V typ.) from low-resistance conduction (RDYN = 20mΩ), enabling superior thermal and electrical performance versus junction-based TVS devices.
Key Specifications

FAQ
What is the maximum continuous operating voltage for RCLAMP0524P.TCT?
RCLAMP0524P.TCT has a reverse stand-off voltage (VRWM) of 22V, meaning it can safely operate continuously at up to 22V DC on the protected line without significant leakage or degradation. This makes RCLAMP0524P.TCT ideal for USB PD 20V systems and other 22V-rated industrial power rails where sustained voltage margin is essential.
How does RCLAMP0524P.TCT achieve stable clamping voltage across temperature and current?
RCLAMP0524P.TCT uses a surge-rated FET activated by a precision trigger circuit instead of a passive PN junction. As surge current increases, the FET's RDS(on) decreases, maintaining clamping near the trigger breakdown voltage (~27.5–28V). This architecture ensures RCLAMP0524P.TCT delivers consistent protection from −40°C to +125°C and across its full 40A rating.
Can RCLAMP0524P.TCT be used on high-speed data lines like USB SuperSpeed or PCIe?
No - RCLAMP0524P.TCT has 175pF junction capacitance at 22V, which is too high for USB 3.x (≤0.3pF typical) or PCIe Gen3+ signaling. It is intended exclusively for DC power lines, low-speed control signals, or bus lines where capacitance is not signal-integrity-critical. For data lines, Semtech recommends RClamp3371ZC (<0.25pF) alongside RCLAMP0524P.TCT in complete USB Type-C solutions.
What is the recommended PCB layout for RCLAMP0524P.TCT to achieve full 40A surge rating?
To achieve RCLAMP0524P.TCT's full 40A rating, 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. Place RCLAMP0524P.TCT within 3mm of the connector entry point to minimize inductive coupling - this layout is validated in Semtech's application notes for RCLAMP0524P.TCT.
Is RCLAMP0524P.TCT compliant with RoHS and halogen-free standards?
Yes - RCLAMP0524P.TCT is Pb-free, halogen-free, and fully compliant with RoHS and WEEE directives. Its molding compound meets UL 94V-0 flammability rating, and the lead finish is lead-free. These compliance attributes are confirmed in Semtech's official datasheet revision 2.5 for RCLAMP0524P.TCT and apply to all units shipped under this part number.
