Product details
Overview
RCLAMP7524T.TNT from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS 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, 20mΩ dynamic resistance, and 175pF junction capacitance - deployed in USB PD, USB Type-C, and industrial load-switch input protection.
For engineers reviewing the RCLAMP7524T.TNT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature and current, low dynamic resistance for minimal voltage overshoot, DFN-6 package layout compatibility, and compliance with IEC 61000-4-2/4-4/4-5 surge standards in high-voltage bus protection.
Technical Context
RCLAMP7524T.TNT 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) under surge conditions.
The device operates over −40°C to +125°C, maintains stable clamping across temperature, and achieves 20mΩ dynamic resistance measured between 1A and 40A (8/20μs). Its 175pF capacitance at 22V/1MHz supports high-speed interfaces without signal integrity degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC operating voltage on protected line without leakage or conduction. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo waveform) - ensures downstream ICs (e.g., USB PD controllers) remain below damage threshold during surge events. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements for 22V systems. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD immunity requirements for external connectors. |
| Dynamic Resistance | 20mΩ - enables flat clamping response and minimizes voltage rise under increasing surge current. |
| Junction Capacitance | 175pF at 22V/1MHz - compatible with USB Type-C VBUS and load-switch control lines where sub-200pF is acceptable. |
| Package | DFN 1.6 × 1.6 × 0.55 mm, 6-lead - enables compact placement near connectors with low-inductance ground paths via three dedicated GND pins. |
Pinout & Package
Package: DFN 1.6 mm × 1.6 mm × 0.55 mm, 6-lead, RoHS-compliant, UL 94V-0 molding compound, lead-free finish, tape-and-reel packaging.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground terminals - all three must be connected to minimize parasitic inductance and maximize surge current handling capability. |
| 4, 5, 6 | IN | Protected line input - connects directly to VBUS or power rail; all three pins are internally tied and must be routed together for uniform current sharing. |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping voltage | 27.5–28V across full 24–40A surge range - eliminates need for oversized IPP margining to meet voltage thresholds. |
| Temperature-stable clamping | No increase in VC from −40°C to +125°C - enables reliable protection in uncontrolled thermal environments (e.g., industrial enclosures). |
| Low dynamic resistance | 20mΩ - reduces IR drop during surge, enabling tighter clamping than TVS diodes with fixed RDYN. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz) - protects against repetitive fast transients in motor drives and PLC I/O. |
| Integrated FET-based architecture | Replaces discrete TVS + MOSFET clamp circuits - reduces BOM count and PCB area vs. traditional solutions. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting 20–22V VBUS lines in USB-C ports supporting up to 100W PD negotiation. IC Role / Device Role / Timing Role: Primary EOS suppressor placed between connector and PD controller or load switch input. Use Value: Maintains 27.5–28V clamping at 40A and 125°C - prevents PD controller latch-up or gate oxide damage during lightning-induced surges. |

IC Role / Device Role / Timing Role: Front-end transient shunt protecting internal FET gate oxide and overvoltage protection circuitry. Use Value: Limits clamping voltage below 30V - avoids triggering OVP false trips or damaging sensitive control logic during 1.2/50μs surges. |
| IoT Edge Node Power Bus Protection | Storage Device 22V Rail Protection |
|
Use Scenario: Securing 22V auxiliary power rails in battery-backed IoT gateways exposed to field ESD and induced surges.

Use Value: Delivers ±30kV ESD robustness and 40A surge handling in <2.6 mm² footprint - critical for space-constrained edge hardware. |
Use Scenario: Protecting 22V supply inputs to NVMe SSD power management ICs and PCIe switch regulators. IC Role / Device Role / Timing Role: High-current transient suppressor on primary VDD rail upstream of PMIC input filtering. Use Value: 175pF capacitance avoids resonance with bulk capacitance while enabling fast turn-on (<10ns) to limit voltage overshoot during hot-plug events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Same 22V working voltage, identical 40A/28V clamping, DFN-6 package, but includes integrated trigger circuit with tighter VBR tolerance (25–27.9V vs. RCLAMP7524T.TNT's typical 27V). | Validated in Semtech's USB Type-C reference designs; slightly higher production volume and longer qualification history. | Select TDS2211P when referencing Semtech's application notes or requiring documented performance at extreme temperature corners. |
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.1V VBR, 40.5V clamping at 32.4A - 12.5V higher clamping than RCLAMP7524T.TNT at rated current. | Lacks constant-clamp behavior; clamping rises with temperature and current - unsuitable for tight-margin 22V systems. | Choose SMAJ22A only for cost-sensitive, non-critical 22V lines where >35V clamping is acceptable and thermal derating is managed externally. |
Compared with TDS2211P, RCLAMP7524T.TNT offers identical electrical specs and package but may differ in traceability, date-code marking, or minor process optimizations; versus SMAJ22A, it delivers 12.5V lower clamping and stable performance across temperature - making it essential for 22V USB PD and industrial power rail protection.

FAQ
What is the maximum continuous operating voltage for RCLAMP7524T.TNT?
The RCLAMP7524T.TNT has a reverse stand-off voltage (VRWM) of 22V, meaning it can continuously block up to 22V DC without significant leakage or conduction. This makes RCLAMP7524T.TNT suitable for protecting 22V power rails such as USB PD VBUS, industrial 24V nominal systems, and storage device auxiliary supplies.
How does RCLAMP7524T.TNT achieve constant clamping voltage across surge current?
RCLAMP7524T.TNT uses a surge-rated FET as its core 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 27.5–28V clamping from 24A to 40A. This behavior is confirmed in the RCLAMP7524T.TNT datasheet's clamping vs. IPP curves.
Is RCLAMP7524T.TNT compatible with automated SMT assembly processes?
Yes, RCLAMP7524T.TNT is supplied in a standard DFN 1.6 × 1.6 mm package with lead-free, RoHS-compliant finish and tape-and-reel packaging (3,000 units/reel). Its land pattern matches IPC-7351B guidelines, and the device supports standard reflow profiles - including peak temperatures up to 260°C - as validated in Semtech's assembly recommendations for RCLAMP7524T.TNT.
Can RCLAMP7524T.TNT protect both power and data lines?
RCLAMP7524T.TNT is optimized for power-line and high-voltage I/O protection (e.g., VBUS, load-switch inputs) with 175pF capacitance - too high for high-speed data lanes like USB SS or PCIe. For those, Semtech recommends pairing RCLAMP7524T.TNT with low-capacitance devices like RClamp3371ZC. RCLAMP7524T.TNT itself is not intended for data-line use.
What standards does RCLAMP7524T.TNT meet for surge and ESD immunity?
RCLAMP7524T.TNT meets IEC 61000-4-2 (±30kV contact/air ESD), IEC 61000-4-4 (±4kV EFT), and IEC 61000-4-5 (40A 8/20μs, ±1kV 1.2/50μs combo wave) - all verified per manufacturer test reports. These certifications make RCLAMP7524T.TNT appropriate for industrial, computing, and consumer applications requiring full IEC compliance.
