Product details
Overview
SC2596SETRT 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 SC2596SETRT datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, DFN-6 package layout guidance, real-world clamping stability across temperature and current, and validated alternatives for 22V bus protection designs.
Technical Context
The SC2596SETRT uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events. Unlike conventional TVS diodes, it maintains near-constant clamping voltage due to the FET's decreasing RDS(on) under surge conditions.
Its functional architecture separates input (pins 4–6) and ground (pins 1–3) terminals with low-inductance parallel routing, enabling stable 27.5–28V clamping across –40°C to +125°C and 24–40A surge currents - a key differentiator versus standard TVS devices whose clamping rises linearly with current and temperature.
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 24–40A (1.2/50μs + 8/20μs combo wave, RS = 2Ω) - ensures downstream ICs (e.g., USB PD controllers) remain below damage threshold during surge. |
| 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 robustness standards for connector-facing protection. |
| Dynamic Resistance | 20mΩ (8/20μs, 1–40A range) - enables flat clamping response and minimizes voltage overshoot during fast-rising transients. |
| Junction Capacitance | 175pF at 22V, 1MHz - suitable for DC power rail and low-speed signal line protection; not intended for high-speed data lines. |
Pinout & Package
SC2596SETRT is housed in a RoHS-compliant DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no internal thermal pad required). All six pins must be connected per function to achieve rated 40A surge capability and minimal parasitic inductance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Low-inductance ground return path; all three must be vias-connected to inner ground plane for full 40A rating. |
| Pins 4, 5, 6 | IN | Parallel-connected input terminal for protected line (e.g., USB PD VBus); all three required for uniform current sharing and optimal clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping voltage | 27.5–28V across full 24–40A surge range and –40°C to +125°C - eliminates derating uncertainty in thermal design. |
| FET-based shunt architecture | Replaces junction-limited TVS with low-RDS(on) MOSFET - reduces energy dissipation in silicon and improves reliability under repeated surges. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz bursts) - protects against repetitive switching noise in industrial motor drives and PLCs. |
| Small footprint | 1.6mm × 1.6mm DFN-6 saves >60% board area vs. SO-8 TVS solutions - critical for space-constrained USB Type-C and IoT edge nodes. |
Applications
| USB Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V VBus lines in USB Type-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, clamping transients before they reach sensitive logic. Use Value: Maintains 27.5–28V clamping at full 40A surge and elevated temperatures - prevents false shutdown or latch-up in PD controllers where 30V+ clamping would exceed ABS MAX ratings. |
Use Scenario: Safeguarding input pins of e-fuse or load switches (e.g., HS2950P) in remote meters, robotics, and factory automation equipment. IC Role / Device Role / Timing Role: Front-end transient shunt that limits voltage stress on the load switch's internal FET gate oxide and drain-source junction. Use Value: Enables use of cost-optimized load switches without requiring internal overvoltage protection - extends system lifetime under lightning-induced surges and inductive kickback. |
| IoT Edge Node Power Rail Protection | Notebook/Tablet DC Power Input Protection |
Use Scenario: Securing 12–24V DC input rails in battery-powered IoT gateways exposed to ESD during field servicing or connector mating. IC Role / Device Role / Timing Role: Single-device solution replacing multi-stage TVS + capacitor filtering, placed directly at barrel jack or USB-C port. Use Value: Delivers ±30kV ESD and 40A surge protection in <2.6mm² footprint - preserves PCB real estate while meeting IEC 61000-4-2/4-5 compliance without external components. |
Use Scenario: Protecting main DC input (e.g., 19.5V adapter rail) in ultrabooks and 2-in-1 tablets subject to accidental short-to-VBus or hot-plug transients. IC Role / Device Role / Timing Role: High-energy clamping device positioned upstream of buck converters and battery charge management ICs. Use Value: Limits transient overvoltage to ≤28V - avoids triggering OVP circuits prematurely and prevents damage to 20V-rated input capacitors and PMICs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Identical electrical specs, same DFN-6 package, identical marking and reel packaging - direct form-fit-function replacement. | No difference; fully interchangeable in all documented SC2596SETRT applications including USB PD and load switch protection. | Select TDS2211P when sourcing from Semtech-authorized channels with identical traceability and qualification history. |
| SP1003-02HTG | Lower 30A IPP rating, 33V clamping at 24A, higher 350pF capacitance - lacks flat-clamp behavior and temperature stability of SC2596SETRT. | Suitable only for lower-energy 22V applications where 33V clamping is acceptable and thermal derating is managed externally. | Choose SP1003-02HTG only if legacy design reuse or dual-sourcing mandates a non-Semtech part; expect reduced margin in high-temp or high-IPP scenarios. |
Compared with TDS2211P and SP1003-02HTG, SC2596SETRT delivers identical performance to TDS2211P but with broader supply chain availability, while offering superior clamping stability and lower dynamic resistance than SP1003-02HTG - making it the preferred choice for thermally demanding or high-reliability 22V bus protection.

FAQ
What is the exact package type and dimensions of SC2596SETRT?
SC2596SETRT uses a 6-pin DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed copper pad. Pin 1 is marked by a laser dot; pins 1–3 are GND, pins 4–6 are IN. The land pattern matches Semtech's standardized DFN-6 outline, and all six pins must be soldered for full 40A surge rating. SC2596SETRT does not require an internal thermal pad.
Does SC2596SETRT meet IEC 61000-4-5 Level 4 surge immunity?
Yes, SC2596SETRT is rated for 40A peak pulse current (8/20μs waveform), which satisfies IEC 61000-4-5 Level 4 (±1kV, RS = 42Ω, CS = 0.5μF) for 22V systems. Its 27.5–28V clamping voltage ensures protected ICs remain within safe operating limits during such events - a key advantage over standard TVS diodes whose clamping rises above 35V at this stress level.
Can SC2596SETRT be used on high-speed data lines like USB SuperSpeed or PCIe?
No, SC2596SETRT is not suitable for high-speed data lines. With 175pF junction capacitance at 22V, it introduces excessive signal distortion and insertion loss on differential pairs operating above ~100Mbps. SC2596SETRT is intended exclusively for DC power rails and low-speed control lines (e.g., USB CC, SBU, or load switch enable inputs) where capacitance is non-critical.
How does SC2596SETRT differ from traditional TVS diodes in clamping behavior?
Unlike TVS diodes - whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN) - SC2596SETRT uses a triggered FET to maintain near-constant 27.5–28V clamping from 24A to 40A and across –40°C to +125°C. This eliminates thermal derating and provides predictable protection margins in thermally constrained designs.
Is SC2596SETRT RoHS and REACH compliant?
Yes, SC2596SETRT is Pb-free, halogen-free, and fully compliant with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Its molding compound meets UL 94V-0 flammability rating, and lead finish is matte tin - confirmed in Semtech's official datasheet Rev 2.5 and material declarations.
