Product details
Overview
RCLAMP0594PWQ.C from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection of 22V-rated power or data 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 front-end circuits.
For engineers reviewing the RCLAMP0594PWQ.C datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, real-world clamping stability across temperature and current, and validated alternatives for 22V bus protection in USB PD, IoT, and industrial equipment designs.
Technical Context
The RCLAMP0594PWQ.C implements a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events and rapidly shunts transient current to ground. Unlike conventional TVS diodes, its clamping voltage remains nearly constant across the full 40A peak pulse range due to the FET's collapsing RDS(on).
It operates with a 22V reverse stand-off voltage (VRWM), 25–27.9V breakdown (VBR), and maintains stable clamping (27.5–28V) from −40°C to +125°C - confirmed by thermal characterization curves showing <±0.5V drift over temperature at 40A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-Off Voltage | 22 V - defines maximum continuous operating voltage before conduction begins; matches USB PD 20V nominal + margin. |
| Clamping Voltage (40A, 8/20μs) | 27.5–28 V - ensures protected ICs (e.g., USB PD controllers) remain below absolute maximum ratings during worst-case surges. |
| Peak Pulse Current | 40 A - supports compliance with IEC 61000-4-5 Level 4 (±1 kV, 42Ω source) on unsymmetrical lines. |
| ESD Withstand | ±30 kV contact & air - exceeds IEC 61000-4-2 Level 4, enabling robust handling in manufacturing and end-user environments. |
| Dynamic Resistance | 20 mΩ - enables low-voltage drop under surge, minimizing energy dissipation in the device and reducing thermal stress. |
| Junction Capacitance | 175 pF @ 22 V, 1 MHz - suitable for DC/low-speed power line protection; not intended for high-speed signal lines (e.g., USB SS). |
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.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current; all three pins must be connected to maximize current sharing and minimize parasitic inductance. |
| 4, 5, 6 | IN | Protected line input (e.g., VBUS in USB Type-C); parallel connection of all three pins ensures uniform current distribution and full 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping voltage vs. current | 27.5–28 V across 24–40 A (8/20μs) - eliminates design margin inflation required with traditional TVS diodes. |
| Temperature-stable clamping | <±0.5 V variation from −40°C to +125°C at 40A - enables reliable protection in uncontrolled thermal environments (e.g., industrial enclosures). |
| Low dynamic resistance | 20 mΩ - reduces I²R heating during surge, extending device lifetime and improving single-pulse survivability. |
| High EFT immunity | ±4 kV per IEC 61000-4-4 (5/50 ns, 100 kHz & 5 kHz) - protects against repetitive fast transients in motor drives and PLC I/O modules. |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Front-End Protection |
|---|---|
|
Use Scenario: Protecting the VBUS line of a USB Type-C receptacle supporting up to 20V/5A PD negotiation against lightning-induced surges and connector ESD. IC Role / Device Role / Timing Role: Transient diverting suppressor placed directly at the connector, clamping overvoltage before it reaches the PD controller and load switch. Use Value: Maintains 27.5–28 V clamping at 40A and 125°C - prevents damage to 30V-rated PD controllers where conventional TVS would exceed 35V at same conditions. |
Use Scenario: Safeguarding the input of an industrial-grade load switch (e.g., HS2950P) exposed to field wiring transients in remote meters or robotics. IC Role / Device Role / Timing Role: Primary EOS shunt device absorbing 8/20μs surges before they stress the load switch's internal FET gate oxide or drain-source junction. Use Value: 20 mΩ dynamic resistance limits voltage overshoot during fast-rising transients, keeping clamp energy within the load switch's safe operating area. |
| IoT Device DC Power Rail Protection | Storage Device 22V Backup Supply Protection |
|
Use Scenario: Securing the 22V auxiliary power rail of a battery-backed smart sensor node subjected to ESD during field servicing or installation. IC Role / Device Role / Timing Role: Standoff protector with 22V VRWM, conducting only during EOS events while presenting <600 nA leakage at rated voltage. Use Value: 175 pF capacitance avoids signal integrity issues on DC rails, and ±30 kV ESD rating eliminates need for secondary ESD staging. |
Use Scenario: Shielding the 22V backup supply input of an NVMe SSD module from power rail surges during hot-swap or power sequencing faults. IC Role / Device Role / Timing Role: High-energy transient diverter placed between connector and DC-DC converter input, rated for repeated 40A pulses. Use Value: Stable 28 V clamping ensures downstream converters remain within overvoltage lockout thresholds even after multiple surge 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.C | Identical datasheet, same package, identical marking code T22 - confirmed direct variant of RCLAMP0594PWQ.C per Semtech ordering documentation. | Same 22V VRWM, 40A rating, DFN-6 footprint - functionally interchangeable with no layout change. | Select when sourcing through Semtech-authorized channels requiring explicit TDS-series part numbering. |
| uClamp2411ZA.TCT | 24V VRWM, ±30kV ESD, 24A IPP, SOD-323 package - lower surge rating and different footprint. | Suitable for CC/SBU lines in USB Type-C, not for 22V VBUS; higher VRWM increases risk of false triggering on 22V rails. | Use only for lower-energy signal-line protection; not a functional replacement for RCLAMP0594PWQ.C in power rail roles. |
Compared with RCLAMP0594PWQ.C, TDS2211P.C offers identical electrical and mechanical performance with equivalent traceability, while uClamp2411ZA.TCT provides higher working voltage but insufficient peak current and incompatible packaging for VBUS-level protection.

FAQ
What is the exact package type and dimensions of RCLAMP0594PWQ.C?
RCLAMP0594PWQ.C uses a DFN package measuring 1.6 mm × 1.6 mm × 0.55 mm with 6 leads. Pin 1–3 are GND terminals; pins 4–6 are IN terminals. The land pattern requires symmetric copper pour and multiple vias to ground for optimal surge current handling - details are specified in Semtech's outline drawing DS-TDS2211P-001.
Does RCLAMP0594PWQ.C meet IEC 61000-4-5 Level 4 surge immunity?
Yes, RCLAMP0594PWQ.C is rated for 40A peak pulse current (8/20μs waveform), which satisfies IEC 61000-4-5 Level 4 (±1 kV with 42Ω source impedance) for unsymmetrical lines. Its 27.5–28V clamping voltage at 40A ensures protected circuitry remains within safe operating limits during such events.
How does RCLAMP0594PWQ.C differ from standard TVS diodes in clamping behavior?
RCLAMP0594PWQ.C uses a surge-rated FET and precision trigger circuit instead of a pn-junction. This yields near-constant clamping voltage (27.5–28V) across 24–40A and −40°C to +125°C - unlike TVS diodes whose clamping rises linearly with current and temperature due to fixed dynamic resistance.
Can RCLAMP0594PWQ.C be used on high-speed USB SuperSpeed lines?
No, RCLAMP0594PWQ.C is not suitable for USB SuperSpeed (TX/RX) lines due to its 175pF junction capacitance, which would degrade signal integrity. For those lines, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF); RCLAMP0594PWQ.C is intended exclusively for DC or low-speed power/data lines such as VBUS, CC, or SBU.
What is the maximum operating temperature range for RCLAMP0594PWQ.C?
RCLAMP0594PWQ.C is specified for continuous operation from −40°C to +125°C ambient temperature. Electrical characteristics including clamping voltage (27.5–28V at 40A) and leakage current (<600nA at 22V) are guaranteed across this full range, as validated in the TDS2211P datasheet's thermal characterization plots.
