Product details
Overview
SC5012MLTRT 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), and a stable 27.5–28V clamping voltage across temperature and current range. It is used in USB Type-C PD input protection to safeguard controllers from voltage overshoot during lightning surges or connector hot-plug events.
For engineers reviewing the SC5012MLTRT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability under 40A transients, DFN-6 thermal and surge robustness, low 20mΩ dynamic resistance, and compatibility with industrial and portable power delivery systems requiring <30V clamping at 125°C.
Technical Context
The SC5012MLTRT employs a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage beyond ~25V breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly constant-27.5–28V-across 24A to 40A peak pulses due to decreasing RDS(on) under surge conditions.
It operates from −40°C to +125°C with <600nA reverse leakage at 22V, 175pF junction capacitance at 22V/1MHz, and is housed in a 1.6mm × 1.6mm × 0.55mm DFN-6 package with three dedicated IN pins (4–6) and three GND pins (1–3), all requiring connection for full 40A rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC bus voltage it can protect without leakage or degradation |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures protected ICs (e.g., USB PD controllers) remain below damage threshold during worst-case surge |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD robustness standards |
| Dynamic Resistance | 20mΩ - enables low-voltage drop under high-current surge, minimizing energy dissipation in the device |
| Junction Capacitance | 175pF at 22V/1MHz - low enough for 20V power rail protection without signal integrity impact on adjacent traces |
Pinout & Package
SC5012MLTRT is packaged in a Pb-free, RoHS-compliant DFN-6 (1.6mm × 1.6mm × 0.55mm) with exposed pad not electrically connected. All six terminals are surface-mount; no thermal pad required as surge energy is dissipated in the FET channel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected to maximize current sharing and minimize inductance |
| 4, 5, 6 | IN | Protected line input (e.g., VBUS in USB-C); parallel connection ensures uniform current distribution and full 40A rating |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping across IPP & temperature | 27.5–28V clamping maintained from −40°C to +125°C and 24A–40A, unlike TVS diodes whose VC rises linearly with current/temp |
| FET-based shunt architecture | Surge-rated MOSFET replaces pn-junction, enabling sub-0.1Ω effective RDS(on) and minimal thermal derating |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 100kHz/5kHz) - protects against repetitive fast transients in motor drives and PLCs |
| Low leakage & capacitance | <600nA IR at 22V and 175pF CJ - avoids standby power loss and signal coupling in always-on power rails |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20V–22V VBUS lines in USB-C receptacles from ESD, lightning-induced surges, and hot-plug transients. IC Role / Device Role / Timing Role: Primary high-energy shunt suppressor placed directly at connector, clamping transient energy before it reaches PD controller or load switch. Use Value: Maintains 28V clamping at 125°C - prevents controller latch-up or gate oxide damage where standard TVS would exceed 35V at same condition. |
Use Scenario: Safeguarding input of industrial-grade load switches (e.g., HS2950P) in remote meters, robotics, and factory automation equipment. IC Role / Device Role / Timing Role: Front-end EOS protector that limits voltage seen by the switch's internal FET during 1kV/42Ω surge events. Use Value: Enables use of smaller, lower-cost load switches by keeping clamp voltage below their absolute maximum drain-source rating (e.g., <30V). |
| IoT Device Power Rail Protection | Notebook/Tablet Main Power Bus Protection |
Use Scenario: Securing 12–22V system rails in battery-powered IoT edge nodes exposed to field ESD and induced surges. IC Role / Device Role / Timing Role: Single-device solution replacing multi-stage TVS+MOV designs, reducing BOM count and PCB area. Use Value: 1.6mm × 1.6mm footprint saves >60% board space vs. SOT-23 TVS alternatives while delivering higher surge rating. |
Use Scenario: Protecting main power input (e.g., barrel jack or USB-C PD input) in thin-client notebooks and tablets operating up to 22V. IC Role / Device Role / Timing Role: High-reliability transient suppressor co-located with input connector to prevent surge coupling into PMIC or battery charge circuitry. Use Value: Stable clamping ensures consistent protection margin across ambient temperatures-from cold storage to sustained CPU load heating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Same die, identical electrical specs and package; SC5012MLTRT is Semtech's alternate ordering code for TDS2211P | No functional difference; both qualified for USB-C PD and industrial surge standards | Select based on distributor stock and reel size preference (SC5012MLTRT = 3,000/reel, tape width 8mm) |
| uClamp2411ZA | 24V working voltage, lower 24A IPP rating, ±30kV ESD, but uses silicon avalanche diode-not FET-based-so clamping rises with temperature | Suitable for CC/SBU lines or lower-energy 24V rails; not recommended for 40A VBUS protection | Use uClamp2411ZA only where peak current ≤24A and temperature stability is secondary to cost |
Compared with TDS2211P and uClamp2411ZA, SC5012MLTRT offers identical performance to TDS2211P with full 40A/28V clamping stability, while uClamp2411ZA provides lower-cost protection for non-critical 24V lines but lacks constant-clamp behavior under thermal stress.

FAQ
What is the exact package type and dimensions of SC5012MLTRT?
SC5012MLTRT uses a 6-pin DFN package measuring 1.6mm × 1.6mm × 0.55mm with no thermal pad. Pin 1 is marked by a laser dot; pins 1–3 are GND, pins 4–6 are IN. The land pattern requires full copper connection to ground plane via multiple vias for optimal 40A surge handling. SC5012MLTRT's compact size enables placement directly at USB-C connectors with minimal trace inductance.
How does SC5012MLTRT achieve constant clamping voltage across temperature and current?
SC5012MLTRT achieves constant clamping by using a surge-rated FET instead of a pn-junction. When triggered, the FET's RDS(on) decreases under higher current, counteracting voltage rise-resulting in stable 27.5–28V clamping from −40°C to +125°C and 24A–40A. This differs fundamentally from TVS diodes, whose VC = VBR + IPP × RDYN increases linearly with both current and temperature.
Is SC5012MLTRT pin-compatible with other Semtech TDS devices like TDS2211P?
Yes-SC5012MLTRT is a direct orderable variant of TDS2211P with identical pinout, electrical specifications, and package. Both share the same DFN-6 layout, terminal assignment (GND on pins 1–3, IN on pins 4–6), and functional diagram. No PCB redesign is needed when substituting SC5012MLTRT for TDS2211P in existing designs.
What is the maximum continuous operating voltage for SC5012MLTRT?
The maximum continuous operating (reverse stand-off) voltage for SC5012MLTRT is 22V. It is rated for reliable operation up to this DC or RMS voltage without significant leakage (<600nA) or degradation. Exceeding 22V risks premature triggering or accelerated wear; for 24V systems, uClamp2411ZA or TDS2411P would be appropriate alternatives.
Can SC5012MLTRT be used to protect high-speed data lines such as USB SuperSpeed or PCIe?
No-SC5012MLTRT is not intended for high-speed data line protection. Its 175pF junction capacitance is optimized for power rail or low-frequency I/O protection (e.g., VBUS, CC, SBU). For USB SS, DP/DM, or PCIe lanes, Semtech recommends ultra-low-capacitance devices like RClamp3371ZC (<0.25pF) to avoid signal integrity degradation and insertion loss.
