Product details
Overview
SC2598SETRC 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, and 20mΩ dynamic resistance. It protects USB PD, USB Type-C VBus, and load switch inputs in industrial and portable electronics.
For engineers reviewing the SC2598SETRC datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, temperature-stable clamping behavior, and direct alternatives for EOS-critical bus protection designs.
Technical Context
The SC2598SETRC 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 across 24–40A and −40°C to +125°C due to decreasing RDS(on) under surge conditions.
It operates with a 22V reverse stand-off voltage (VRWM), 25–27.9V breakdown (VBR), and 175pF junction capacitance at 22V/1MHz - enabling low-distortion protection without signal integrity compromise in high-speed power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD VBus and industrial 24V rail systems without derating. |
| Clamping Voltage | 27.5–28V at 24–40A (1.2/50μs + 8/20μs combo wave) - stays below 30V damage threshold of common load switches and PD controllers. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds Class 4 requirements for handheld and connector-facing applications. |
| Dynamic Resistance | 20mΩ - ensures minimal voltage rise during surge conduction, critical for maintaining downstream device safety margins. |
| Junction Capacitance | 175pF at 22V/1MHz - low enough to avoid power rail instability while supporting fast transient response. |
| Operating Temperature | −40°C to +125°C - supports extended-range operation in automotive-grade and industrial enclosures. |
Pinout & Package
SC2598SETRC is housed in a Pb-free, RoHS-compliant DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad not required - all six terminals are functional and must be connected for full 40A surge rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path - all three pins must be tied to solid ground plane via multiple vias to minimize inductance and maximize surge current handling. |
| 4, 5, 6 | IN | Protected line input - connects directly to VBus or power rail; all three pins conduct surge current in parallel to achieve rated 40A capability. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies <0.5V across 24–40A and −40°C to +125°C - eliminates thermal derating uncertainty in high-temp environments. |
| FET-based shunt topology | Replaces traditional TVS junction with low-RDS(on) MOSFET - dissipates energy in channel rather than PN junction, improving reliability under repeated surges. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 100kHz/5kHz) - protects against burst noise in motor drives and PLC I/O modules. |
| Low leakage | 130–600nA at 22V - minimizes standby power loss in battery-powered IoT and portable devices. |
| Small-footprint packaging | 1.6mm × 1.6mm DFN-6 - saves >60% board area vs. SO-8 TVS solutions while maintaining full surge rating. |
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 from hot-plug events and lightning-induced surges. IC Role / Device Role / Timing Role: Primary EOS suppressor placed between connector and PD controller/load switch, clamping transients before they reach sensitive silicon. Use Value: Maintains 27.5–28V clamping across temperature and current - avoids overvoltage damage to USB PD controllers rated for ≤30V absolute maximum. |
Use Scenario: Safeguarding the input of an industrial-grade load switch (e.g., HS2950P) in remote metering or robotics systems subject to 1kV/42Ω surges per IEC 61000-4-5. IC Role / Device Role / Timing Role: Front-end transient diverter that routes surge current away from the load switch's internal FET drain-source path. Use Value: Limits voltage across load switch terminals to <28V during 40A surges - prevents gate oxide rupture and latch-up in high-side switching ICs. |
| IoT Device Power Rail Protection | Notebook/Tablet Main Power Input Protection |
Use Scenario: Securing the 22V-rated DC input of a cellular-connected smart sensor node deployed in ungrounded outdoor enclosures. IC Role / Device Role / Timing Role: Single-device solution for combined ESD, EFT, and surge protection on the main power entry point. Use Value: Delivers ±30kV ESD, ±4kV EFT, and 40A surge capability in one 1.6mm² footprint - eliminates need for multi-stage protection networks. |
Use Scenario: Hardening the 20V input rail of a thin-and-light notebook or tablet against accidental adapter misconnection and electrostatic discharge during docking. IC Role / Device Role / Timing Role: First-line defense against fast-rising transients entering via barrel jack or USB-C port before reaching PMIC or battery charger. Use Value: 175pF capacitance avoids power rail resonance issues; stable clamping ensures no brownout or reset during 24A 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 electrical specs, same DFN-6 package, identical marking code T22 - confirmed drop-in replacement per Semtech ordering documentation. | No functional difference; used interchangeably in USB PD reference designs. | Select TDS2211P.C when sourcing from authorized Semtech distributors with standard reel packaging. |
| uClamp2411ZA | 24V working voltage, lower 20A IPP rating, higher 33V clamping at 20A, SOD-323 package - not pin-compatible and lacks constant-clamp architecture. | Suitable only for CC/SBU lines in USB-C, not for VBus or power rail protection. | Choose uClamp2411ZA only for low-capacitance (<0.5pF), low-current signal line protection - not a substitute for SC2598SETRC in power rail roles. |
Compared with TDS2211P.C (identical function and form) and uClamp2411ZA (lower surge rating, different topology), SC2598SETRC provides guaranteed 40A/28V clamping in a compact DFN-6 - making it the sole choice for high-reliability 22V power rail EOS protection where thermal stability and surge margin are critical.

FAQ
What is the exact package type and dimensions of SC2598SETRC?
SC2598SETRC uses a DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with three GND pins (1–3) and three IN pins (4–6). The package is Pb-free, halogen-free, and RoHS/WEEE compliant, with UL 94V-0 molding compound. No thermal pad is required - all six terminals are electrically active and must be soldered for full 40A rating.
Does SC2598SETRC provide constant clamping voltage across temperature and current?
Yes. SC2598SETRC maintains a clamping voltage of 27.5–28V across 24–40A (8/20μs) and from −40°C to +125°C. This stability results from its FET-based shunt architecture, where RDS(on) decreases under surge, unlike conventional TVS diodes whose clamping rises linearly with current and temperature.
Can SC2598SETRC replace standard TVS diodes in 22V power rail protection?
Yes - SC2598SETRC is explicitly designed as a superior alternative to 22V TVS diodes. Its 20mΩ dynamic resistance, 27.5–28V clamping, and ±30kV ESD rating outperform typical TVS devices in both surge margin and thermal stability. However, pinout differs (6-pin DFN vs. DO-214/SMC), so PCB layout must be updated.
What is the maximum surge current rating for SC2598SETRC and which standard does it meet?
SC2598SETRC is rated for 40A peak pulse current with 8/20μs waveform, meeting IEC 61000-4-5 Level 4 surge immunity. It also withstands ±1kV (1.2/50μs voltage + 8/20μs current, RS = 42Ω) for unsymmetrical lines - a common requirement in industrial power interface standards.
Is SC2598SETRC suitable for USB Type-C VBus protection in PD applications?
Yes. SC2598SETRC is optimized for USB Type-C VBus protection, supporting up to 22V operating voltage and clamping at ≤28V during 40A surges - well below the 30V damage threshold of most USB PD controllers. Its low 175pF capacitance avoids interference with PD communication signaling.
