Product details
Overview
RCLAMP7522T.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, and ultra-low 20mΩ dynamic resistance. It protects USB PD, USB Type-C VBus, and load switch inputs in industrial and portable electronics.
For engineers reviewing the RCLAMP7522T.TNT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature and current, DFN-6 package layout constraints, 22V working voltage compliance, and FET-based shunt architecture versus conventional TVS diodes.
Technical Context
The RCLAMP7522T.TNT uses a surge-rated MOSFET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events. Unlike standard TVS diodes, its clamping voltage remains nearly constant-27.5–28V-from 24A to 40A peak pulse current due to decreasing RDS(on) under surge conditions.
It operates across –40°C to +125°C with stable junction capacitance (175pF @ 22V, 1MHz) and reverse leakage (<600nA @ 22V), and is rated for 1120W peak pulse power. Its functional architecture isolates protection path (Pins 4–6) from ground return (Pins 1–3), requiring all six pins to be connected for full 40A capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches USB PD VBus nominal and max operating voltage, enabling direct placement on power rails without derating. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave) - stays below typical 30V damage threshold of USB PD controllers and load switches. |
| ESD Rating | ±30kV contact & air (IEC 61000-4-2) - exceeds Level 4 immunity requirements for consumer and industrial interfaces. |
| Peak Pulse Current | 40A (8/20μs) - satisfies IEC 61000-4-5 Level 3 (±1kV, RS = 42Ω) for industrial equipment surge protection. |
| Dynamic Resistance | 20mΩ - enables low-voltage-drop shunting, minimizing energy dissipation in the device and reducing thermal stress during repeated surges. |
| Junction Capacitance | 175pF @ 22V, 1MHz - compatible with DC-coupled 22V power line protection; not intended for high-speed data lines. |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, RoHS-compliant, UL 94V-0 molding compound, lead-free finish. Pin 1 marked with laser dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | Ground (GND) | Low-inductance return path for surge current; all three must be connected to solid ground plane via multiple vias for full 40A rating. |
| Pins 4, 5, 6 | Input (IN) | Protected line connection (e.g., USB PD VBus); all three pins are internally paralleled and must be tied together externally to minimize trace inductance. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based shunt architecture | Enables flat clamping curve (27.5–28V) across 24–40A and –40°C to +125°C - eliminates thermal derating concerns common with TVS diodes. |
| Ultra-low dynamic resistance | 20mΩ ensures minimal IR drop during surge, preserving voltage margin for downstream ICs and reducing localized heating. |
| High-energy surge handling | 1120W peak pulse power (8/20μs) supports robust protection against lightning-induced transients in industrial and metering applications. |
| Compact DFN footprint | 1.6mm × 1.6mm area saves >50% board space vs. SOT-23 or SOIC alternatives while maintaining 6-terminal current sharing. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting the VBus line of a USB Type-C port supporting up to 20V/5A PD negotiation, exposed to ESD and system-level surges. IC Role / Device Role / Timing Role: Transient diverting suppressor placed directly at the connector, clamping overvoltage before it reaches the PD controller or buck converter. Use Value: Maintains 27.5–28V clamping across temperature and current, preventing damage to 30V-rated PD controllers where conventional TVS would exceed safe limits at elevated temperatures. |
Use Scenario: Securing the input of an industrial-grade load switch (e.g., HS2950P) powering remote sensors or actuators in smart meters or robotics. IC Role / Device Role / Timing Role: Primary front-end EOS protector, absorbing 40A surges induced by inductive switching or lightning coupling on long cables. Use Value: Keeps clamping voltage below the internal FET breakdown threshold of the load switch, avoiding catastrophic failure during repeated surge events. |
| IoT Device Power Rail Protection | Notebook/Tablet Main Power Input Protection |
Use Scenario: Safeguarding the 22V input rail of battery-powered IoT gateways with cellular or LoRaWAN connectivity, deployed in electrically noisy environments. IC Role / Device Role / Timing Role: Standalone EOS suppressor on the main DC input, coordinated with upstream fusing and downstream DC-DC regulation. Use Value: Delivers ±30kV ESD immunity and 40A surge capacity in a 1.6mm² footprint, enabling compact, ruggedized designs without sacrificing protection integrity. |
Use Scenario: Protecting the 20V input stage of ultrabooks or 2-in-1 tablets using USB-C charging, where space and thermal management are critical. IC Role / Device Role / Timing Role: High-density transient suppressor mounted adjacent to the USB-C receptacle, minimizing PCB trace length to reduce inductive overshoot. Use Value: Stable 27.5–28V clamping ensures compatibility with 30V-rated PMICs and battery charge controllers, even under sustained 85°C ambient operation. |
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, identical DFN-6 package; differs only in reel packaging (3,000 pcs/reel vs. RCLAMP7522T.TNT's unspecified quantity). | No functional difference; both qualified for USB PD and industrial load switch protection per same datasheet Rev 2.5. | Select TDS2211P.C when standard Semtech reel packaging is required; RCLAMP7522T.TNT may reflect alternate distribution channel marking or tape configuration. |
| SMAJ22A | Standard unidirectional TVS diode; 22V standoff, 35.5V min clamping at 10A (8/20μs); no flat-clamp behavior - clamping rises with current and temperature. | Suitable for lower-energy ESD-only scenarios; cannot meet 40A/27.5V requirement for IEC 61000-4-5 Level 3 surge. | Choose SMAJ22A only for cost-sensitive, non-surge-critical applications where clamping voltage margin >8V is acceptable and thermal derating is managed externally. |
Compared with TDS2211P.C, RCLAMP7522T.TNT offers identical protection performance but may differ in traceability or logistics coding; compared with SMAJ22A, RCLAMP7522T.TNT delivers 12V lower clamping at full surge current and eliminates temperature-dependent voltage drift-critical for protecting modern 30V-tolerant power ICs.

FAQ
What is the maximum clamping voltage of RCLAMP7522T.TNT at 40A surge current?
The RCLAMP7522T.TNT clamps at 27.5–28V under IEC 61000-4-5 combination waveform (1.2/50μs voltage + 8/20μs current, RS = 2Ω) at 40A peak pulse current. This value is guaranteed across –40°C to +125°C and reflects its FET-based architecture, not a fixed VBR + IPP×RDYN relationship.
Is RCLAMP7522T.TNT pin-compatible with TDS2211P.C?
Yes, RCLAMP7522T.TNT and TDS2211P.C share identical DFN-6 pinout (Pins 1–3 = GND, Pins 4–6 = IN), mechanical dimensions (1.6mm × 1.6mm × 0.55mm), and electrical specifications per Semtech Rev 2.5 datasheet. They differ only in part marking and packaging logistics-not in function or layout.
Can RCLAMP7522T.TNT be used on high-speed data lines like USB SuperSpeed differential pairs?
No, RCLAMP7522T.TNT is not suitable for high-speed data lines. Its 175pF junction capacitance is optimized for 22V DC power rail or low-frequency I/O protection. For USB SS, DP/DM, or other <1pF-critical paths, Semtech recommends RClamp3371ZC (0.18pF) instead of RCLAMP7522T.TNT.
What is the recommended PCB layout for RCLAMP7522T.TNT to achieve full 40A surge rating?
To achieve the full 40A rating, connect all three GND pins (1, 2, 3) to a solid ground plane using ≥3 thermal vias per pin, and tie all three IN pins (4, 5, 6) together with a short, wide copper trace directly to the protected line. Place RCLAMP7522T.TNT within 5mm of the connector to minimize parasitic inductance.
Does RCLAMP7522T.TNT require external biasing or control signals to operate?
No, RCLAMP7522T.TNT is fully passive and requires no external power, bias, or control signals. Its internal trigger circuit activates the shunt FET automatically when transient voltage exceeds the breakdown threshold; operation is immediate and autonomous upon overvoltage detection.
