Product details
Overview
RCLAMP0524PQTCT 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 24–40A, and 175pF junction capacitance - deployed in USB Type-C PD bus protection and industrial load switch input stages.
For engineers reviewing the RCLAMP0524PQTCT datasheet, pinout, applications, or equivalent options, key selection criteria include its constant-clamp behavior across temperature and current, low dynamic resistance (20mΩ), DFN 1.6×1.6mm package footprint, and compatibility with 22V operating voltage rails requiring robust surge resilience without thermal derating penalties.
Technical Context
The RCLAMP0524PQTCT uses a surge-rated FET as the 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) under surge conditions.
It operates over –40°C to +125°C with stable clamping performance, exhibits only 130–600nA reverse leakage at 22V, and delivers 1120W peak pulse power handling. Its functional architecture separates trigger threshold (25–27.9V VBR) from clamping level, enabling predictable protection margins for 22V systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC or RMS operating voltage on protected line without leakage or degradation |
| Clamping Voltage | 27.5–28V at 24–40A (1.2/50μs + 8/20μs combo wave, RS = 2Ω) - ensures downstream ICs see ≤28V during worst-case surges |
| Peak Pulse Current | 40A (8/20μs) - supports IEC 61000-4-5 Level 4 industrial surge immunity testing |

Use Scenario: Protecting 22V backup supply lines in enterprise SSDs and NVMe storage modules against hot-plug transients and board-level ESD. IC Role / Device Role / Timing Role: High-reliability clamping device placed at power entry to prevent data corruption or controller latch-up during power cycling. Use Value: 175pF capacitance poses no signal integrity penalty on DC power paths - unlike low-capacitance TVS solutions optimized for data lines. |
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 and DFN 1.6×1.6mm package - differs only in tape-and-reel packaging (3,000 pcs/reel vs. RCLAMP0524PQTCT's unspecified quantity) | No functional difference; suitable for same PCB layout and system-level protection roles | Select TDS2211P.C when standard Semtech reel packaging is required for SMT line compatibility |
| SP1003-02HTG | Higher working voltage (33V), lower clamping (≈36V @ 30A), larger SOD-323 package - lacks constant-clamp FET architecture | Better suited for 33V systems but exhibits rising clamping with current and temperature - less predictable for 22V precision rails | Choose SP1003-02HTG only if 33V tolerance is needed and flat clamping is not required |
Compared with TDS2211P.C, RCLAMP0524PQTCT shares identical protection performance but may differ in reel configuration or traceability marking; versus SP1003-02HTG, RCLAMP0524PQTCT delivers superior 22V-system predictability via constant-clamp behavior and smaller footprint - critical for space-constrained USB-C and industrial modules.

FAQ
What is the exact working voltage rating of the RCLAMP0524PQTCT?
The RCLAMP0524PQTCT has a reverse stand-off voltage (VRWM) of 22V, meaning it reliably blocks up to 22V DC or RMS continuous voltage without significant leakage. This makes RCLAMP0524PQTCT ideal for protecting 22V power rails such as USB-C PD VBus, industrial 24V nominal supplies, and backup power lines where overvoltage margin must be tightly controlled.
Does the RCLAMP0524PQTCT provide constant clamping voltage across surge current levels?
Yes - the RCLAMP0524PQTCT uses a surge-rated FET architecture that maintains clamping voltage between 27.5V and 28V across its full rated peak pulse current range (24A to 40A, 8/20μs). This constant-clamp behavior is confirmed in the datasheet's typical characteristics curves and differentiates RCLAMP0524PQTCT from conventional TVS diodes whose clamping rises linearly with current.
What is the package type and pin configuration of the RCLAMP0524PQTCT?
The RCLAMP0524PQTCT is housed in a DFN 1.6 mm × 1.6 mm × 0.55 mm, 6-lead package. Pins 1–3 are GND terminals; pins 4–6 are IN terminals. All six pins must be soldered - connecting all GND and all IN pins in parallel is required to achieve the full 40A surge rating and optimal thermal performance of the RCLAMP0524PQTCT.
How does the RCLAMP0524PQTCT compare to standard TVS diodes in temperature stability?
Unlike standard TVS diodes whose clamping voltage increases with temperature, the RCLAMP0524PQTCT maintains ~27.5–28V clamping from –40°C to +125°C. This stability is achieved through its FET-based shunt architecture and eliminates thermal derating calculations - a key advantage for RCLAMP0524PQTCT in automotive under-hood, industrial control, and outdoor IoT applications.
Can the RCLAMP0524PQTCT be used for USB Type-C superspeed data line protection?
No - the RCLAMP0524PQTCT has 175pF junction capacitance, which is too high for USB 3.x/SS TX/RX differential pairs requiring sub-0.3pF loading. It is intended for VBus and power-related lines only. For superspeed data lines, Semtech recommends low-capacitance devices like RClamp3371ZC; RCLAMP0524PQTCT serves exclusively as the high-energy front-end protector for the 22V power rail in the same USB-C system.
