Product details
Overview
SC5010HULTRT from Semtech is a Transient Diverting Suppressor (TDS) designed for high-energy EOS protection of 22V-rated power or I/O lines. It delivers ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.6V clamping at 40A, 20mΩ dynamic resistance, and 175pF junction capacitance - enabling robust USB Type-C PD and industrial load switch input protection.
For engineers reviewing the SC5010HULTRT datasheet, pinout, applications, or equivalent options, this page provides verified package mapping, validated clamping stability across temperature, confirmed DFN-6 pin configuration, and real-world design implications for surge-prone bus interfaces.
Technical Context
The SC5010HULTRT uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit when transient voltage exceeds breakdown threshold. Unlike conventional TVS diodes, its clamping voltage remains nearly constant (27.5–28V) across 24–40A IPP and −40°C to +125°C due to decreasing RDS(on) under surge.
It features a low 20mΩ dynamic resistance and 175pF capacitance at 22V/1MHz, enabling fast response without signal integrity degradation on high-speed buses. Its 6-pin DFN (1.6×1.6×0.55mm) integrates three parallel IN terminals (pins 4–6) and three GND terminals (pins 1–3) to minimize parasitic inductance and maximize surge current handling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD bus and industrial 24V rail systems without derating. |
| Clamping Voltage | 27.6V at 40A (8/20μs) - stays below typical 28–30V damage thresholds of USB PD controllers and load switches. |
| Peak Pulse Current | 40A (8/20μs) - satisfies IEC 61000-4-5 Level 4 surge immunity requirements for industrial equipment. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD test mandates. |
| Junction Capacitance | 175pF at 22V/1MHz - compatible with DC-coupled power rails and low-speed control lines; not intended for >1Gbps data lanes. |
| Dynamic Resistance | 20mΩ - ensures minimal voltage rise under surge, enabling predictable clamping independent of current magnitude. |
| Operating Temperature | −40°C to +125°C - supports extended-range operation in automotive under-hood, industrial PLC, and outdoor IoT deployments. |
Pinout & Package
SC5010HULTRT is housed in a Pb-free, RoHS-compliant DFN package measuring 1.6mm × 1.6mm × 0.55mm with wettable flank terminations. The compact footprint saves >60% board area versus SO-8 TVS solutions while supporting automated optical inspection (AOI).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Three parallel ground terminals - must all be connected to low-inductance ground plane via multiple vias to sustain 40A surge current without voltage overshoot. |
| Pins 4, 5, 6 | IN | Three parallel input terminals - connect directly to protected line (e.g., VBUS in USB-C); all three required for full 40A rating and thermal distribution. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies only ±0.5V across 24–40A and −40°C to +125°C - eliminates thermal derating calculations required for standard TVS diodes. |
| Surge-rated FET protection core | Replaces PN-junction avalanche with low-RDS(on) shunt switching - dissipates energy in channel rather than junction, improving reliability under repeated surges. |
| Low dynamic resistance | 20mΩ measured between 1A–40A (8/20μs) - reduces clamping delta-V to <0.8V across full surge range, critical for tight-voltage-margin ICs. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 100kHz/5kHz) - protects against repetitive fast transients in motor drives and relay-switched industrial controls. |
| DFN-6 thermal & layout optimization | Three-input/three-ground symmetry minimizes loop inductance; no thermal pad needed - simplifies PCB stack-up and reduces BOM count vs. thermally enhanced packages. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V VBUS lines in USB-C ports supporting up to 100W PD negotiation. IC Role / Device Role / Timing Role: Primary high-energy EOS suppressor placed at connector entry point, upstream of PD controller and load switch. Use Value: Maintains 27.6V clamping at 40A and 125°C - prevents overvoltage damage to USB PD controllers (e.g., STUSB4500, TUSB7320) where 28V absolute max is common. |
Use Scenario: Safeguarding input of industrial-grade load switches (e.g., ON Semi NIS5132, TI TPS25940) exposed to lightning-induced surges in remote meters or factory automation. IC Role / Device Role / Timing Role: Front-end transient diverter that clamps before internal FET gate oxide breakdown occurs. Use Value: Limits stress on load switch drain-source during 1kV/42Ω combo-wave events - extends device lifetime and avoids field failures in ungrounded installations. |
| IoT Edge Node Power Rail Protection | Storage Device 24V Backup Supply Protection |
Use Scenario: Securing 22V auxiliary power inputs in battery-backed smart sensors deployed outdoors or near AC mains. IC Role / Device Role / Timing Role: Standalone EOS protector for wide-input DC-DC converters (e.g., LM5164, MAX17504) operating from 9–36V rails. Use Value: 175pF capacitance avoids destabilizing feedback loops in current-mode controllers; ±30kV ESD rating prevents latch-up during field servicing. |
Use Scenario: Shielding 24V backup supplies in NVMe SSD enclosures and RAID controllers from hot-swap transients and ESD during module insertion. IC Role / Device Role / Timing Role: Fast-response shunt device placed immediately after connector, before bulk capacitance and LDO regulators. Use Value: 20mΩ dynamic resistance ensures <1V overshoot during 100A-equivalent surge events - preserves data integrity during unexpected power loss recovery sequences. |
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 (T22), same tape-and-reel packaging (3,000/reel). | No functional difference - direct manufacturer-recommended alternate with identical qualification and traceability. | Select TDS2211P.C when requiring Semtech's standard commercial-grade variant with full production documentation and long-term availability assurance. |
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.5V VC @ 12.3A; higher clamping (+7.9V), fixed RDYN (~1.2Ω), degrades with temperature. | Limited to lower-energy surges; unsuitable for sustained 40A or high-temp industrial use due to thermal runaway risk. | Choose SMAJ22A only for cost-sensitive, non-critical 22V rails where clamping >35V is acceptable and ambient stays <85°C. |
Compared with TDS2211P.C, SC5010HULTRT offers identical performance and form factor but may reflect updated wafer fab or test flow; compared with SMAJ22A, it delivers 8.9V lower clamping at rated current and stable protection across temperature - making it essential for voltage-margin-constrained PD and industrial systems.

FAQ
What is the exact package type and dimensions of SC5010HULTRT?
SC5010HULTRT uses a 6-pin DFN package measuring 1.6mm × 1.6mm × 0.55mm with wettable flank terminations. Pin 1 is marked by a laser dot; pins 1–3 are GND, pins 4–6 are IN. This footprint matches JEDEC MO-229 and supports AOI and reflow compatibility per IPC-7351B.
Does SC5010HULTRT require a thermal pad on the PCB?
No, SC5010HULTRT does not require a thermal pad. Its surge energy is dissipated through the channel of the integrated FET rather than the junction, eliminating the need for thermal vias or copper slugs. Layout guidelines emphasize low-inductance grounding via multiple vias to pins 1–3 instead.
How does SC5010HULTRT's clamping voltage behave across temperature?
SC5010HULTRT maintains clamping voltage within 27.5–28V from −40°C to +125°C at 40A (8/20μs). Unlike TVS diodes whose VC rises with temperature, SC5010HULTRT's FET-based architecture ensures stable clamping - verified in Figure 3 of the official datasheet.
Can SC5010HULTRT protect high-speed data lines like USB SS or PCIe?
No, SC5010HULTRT is not suitable for high-speed data lines. Its 175pF junction capacitance is optimized for power rails and low-speed control signals. For USB SuperSpeed or DP/DM lines, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF), as specified in the TDS2211P application note.
Is SC5010HULTRT pin-compatible with TDS2211P.C?
Yes, SC5010HULTRT is pin-compatible and functionally identical to TDS2211P.C - same DFN-6 footprint, identical pinout (pins 1–3 = GND, pins 4–6 = IN), matching electrical specs, and shared qualification data. Both parts share the same marking code "T22" and 3,000-unit tape-and-reel packaging.
