Product details
Overview
RCLAMP7534P.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 24–40A, 175pF junction capacitance, and DFN 1.6×1.6×0.55mm 6-lead package - deployed in USB Type-C PD input protection.
For engineers reviewing the RCLAMP7534P.TNT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature and surge current, low dynamic resistance (<20mΩ), minimal leakage (<600nA at 22V), and compatibility with industrial-grade load switch and USB PD bus protection layouts.
Technical Context
RCLAMP7534P.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) across 24–40A and −40°C to +125°C due to decreasing RDS(on) under surge conditions.
The device implements a three-terminal symmetric configuration: pins 4/5/6 serve as parallel-connected input terminals tied to the protected line, while pins 1/2/3 are bonded together as a common ground return - enabling low-inductance, high-current surge diversion without thermal pad requirement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC or RMS operating voltage on protected line without leakage degradation. |
| Clamping Voltage | 27.5–28V at 24–40A (1.2/50μs + 8/20μs combo wave, RS=2Ω) - ensures downstream 24V-rated ICs (e.g., USB PD controllers) remain below damage threshold during surge. |
| Peak Pulse Current | 40A (8/20μs) - supports compliance with IEC 61000-4-5 Level 4 (±1kV, RS=42Ω, CS=0.5μF) on 22V buses. |
| ESD Withstand | ±30kV contact & air per IEC 61000-4-2 - exceeds automotive and industrial ESD immunity requirements for external connectors. |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for <22V power rail protection but not suitable for high-speed data lines (e.g., USB SS, PCIe). |
| Dynamic Resistance | 20mΩ (measured 1–40A, 8/20μs) - enables flat clamping response and minimizes VCL rise vs. current, unlike TVS diodes with fixed RDYN. |
| Leakage Current | ≤600nA at 22V - ensures negligible standby power loss in always-on industrial or IoT power rails. |
Pinout & Package
Package: DFN 1.6 mm × 1.6 mm × 0.55 mm, 6-lead, Pb-free, RoHS/WEEE compliant, UL 94V-0 molding compound, marked "T22" + date code.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | Ground (GND) | Common low-inductance ground return path; all three must be connected to maximize surge current handling and minimize ground bounce. |
| Pins 4, 5, 6 | Input (IN) | Parallel-connected protected line interface; all three pins carry equal surge current share - required for full 40A rating and optimal clamping performance. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based transient diversion | Replaces traditional TVS diodes with active shunt switching - delivers stable clamping independent of surge amplitude or ambient temperature. |
| Constant clamping over current range | 27.5–28V across 24–40A (vs. >35V for comparable TVS at 40A) - eliminates need for overrated IPP to meet voltage safety margins. |
| Low dynamic resistance | 20mΩ enables sub-1V delta between clamping levels at 24A vs. 40A - critical for protecting tight-voltage-margin 24V logic and power management ICs. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz bursts) - protects against repetitive fast transients in motor drives and industrial control I/O. |
| Small-footprint DFN package | 1.6×1.6mm area saves >60% board space vs. SO-8 or SOT-23 TVS solutions rated for equivalent surge energy. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting VBus lines in USB-C receptacles supporting up to 20V/5A PD, exposed to ESD from hot-plug events and lightning-induced surges on long cables. IC Role / Device Role / Timing Role: Primary high-energy clamping device placed directly at connector, shunting transients before they reach PD controller, e-fuse, or DC-DC converter. Use Value: Maintains 27.5–28V clamping across −40°C to +125°C - prevents false OVP trips and guarantees controller survival where TVS devices exceed 35V at elevated temperature. |
Use Scenario: Safeguarding enable and input pins of industrial-grade load switches (e.g., HS2950P) in remote meters, robotics, and factory automation equipment subject to 40A surge events. IC Role / Device Role / Timing Role: Front-end EOS suppressor that limits voltage stress on internal MOSFET gate oxide and drain-source junction during surge, extending switch lifetime. Use Value: 20mΩ dynamic resistance ensures <0.8V additional drop at 40A - keeps total clamp voltage well below 30V absolute max ratings of typical 30V load switches. |
| IoT Device Power Rail Protection | Storage Device 22V Backup Supply Protection |
|
Use Scenario: Securing 22V auxiliary power inputs in battery-backed smart sensors and edge gateways deployed in uncontrolled environments with frequent ESD exposure. IC Role / Device Role / Timing Role: Standalone transient suppressor on main DC input rail, operating continuously without derating over full industrial temperature range. Use Value: ≤600nA leakage at 22V minimizes quiescent current draw - critical for multi-year battery operation in low-power IoT nodes. |
Use Scenario: Protecting 22V supercapacitor or LiFePO4 backup supplies in enterprise SSDs and NAS enclosures against surges induced by AC mains coupling or hot-swap events. IC Role / Device Role / Timing Role: High-reliability clamping element placed between backup source and system PMIC, ensuring uninterrupted power delivery during transients. Use Value: 1120W peak pulse power rating (8/20μs) handles repeated 1kV/42Ω surges without parametric shift - validated for >1000 surge events in accelerated life testing. |
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 pcs for .TNT). | No functional difference; both qualified for USB PD and industrial load switch use cases. | Select RCLAMP7534P.TNT for high-volume production with standard 10k/reel logistics; TDS2211P.C suits prototyping or smaller-batch builds. |
| uClamp2411ZA | 24V working voltage, lower 24A IPP rating, higher 30V clamping (at 24A), 120pF capacitance - optimized for CC/SBU lines, not power rails. | Designed for low-voltage, low-capacitance signal-line protection; unsuitable for 22V bus clamping due to higher VCL and lower surge rating. | Use uClamp2411ZA only for USB-C configuration channel or sideband use lines; RCLAMP7534P.TNT remains mandatory for VBus and power input protection. |
Compared with TDS2211P.C, RCLAMP7534P.TNT offers identical protection performance with optimized logistics packaging; versus uClamp2411ZA, it delivers 67% higher surge current capacity and 2.5V lower clamping - making it the sole qualified solution for 22V power rail EOS hardening.

FAQ
What is the maximum continuous operating voltage for RCLAMP7534P.TNT?
RCLAMP7534P.TNT has a reverse stand-off voltage (VRWM) of 22V, meaning it can sustain up to 22V DC or RMS on the protected line indefinitely without significant leakage or degradation. This makes RCLAMP7534P.TNT ideal for 20V USB PD VBus and 22V industrial power rails where overvoltage margin is tightly constrained.
Does RCLAMP7534P.TNT require a thermal pad on the PCB?
No, RCLAMP7534P.TNT does not require a thermal pad. Its FET-based architecture dissipates surge energy primarily through conduction rather than junction heating, and the DFN package relies on direct copper connection of all GND pins (1–3) and IN pins (4–6) to achieve low-inductance current paths. Layout guidelines emphasize multiple vias to ground plane instead of thermal relief.
How does RCLAMP7534P.TNT differ from standard TVS diodes in clamping behavior?
Unlike TVS diodes whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN), RCLAMP7534P.TNT maintains near-constant clamping (27.5–28V) from 24A to 40A due to its active FET shunt with decreasing RDS(on). This eliminates design uncertainty caused by temperature-dependent VC drift - a key advantage confirmed in RCLAMP7534P.TNT's datasheet curves.
Can RCLAMP7534P.TNT be used on high-speed data lines like USB SuperSpeed?
No, RCLAMP7534P.TNT is not suitable for USB SuperSpeed (SS), PCIe, or other high-speed differential data lines. Its 175pF junction capacitance would severely degrade signal integrity. RCLAMP7534P.TNT is specifically intended for 22V power or low-speed control lines; for SS lanes, Semtech recommends RClamp3371ZC (<0.25pF) - a separate device not interchangeable with RCLAMP7534P.TNT.
What is the recommended PCB layout for optimal surge performance of RCLAMP7534P.TNT?
Place RCLAMP7534P.TNT as close as possible to the protected connector. Connect all three IN pins (4/5/6) via a single short, wide trace to the line; tie all three GND pins (1/2/3) directly to a solid ground plane using ≥3 vias. Avoid stubs or splits - this layout minimizes parasitic inductance and ensures full 40A rating and consistent 27.5–28V clamping, as validated in RCLAMP7534P.TNT's application notes.
