Product details
Overview
SC700HWLTRC 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 - enabling robust USB Type-C PD bus protection in notebooks and industrial equipment.
For engineers reviewing the SC700HWLTRC datasheet, pinout, applications, or equivalent options, key selection criteria include its constant-clamp FET architecture, DFN 1.6×1.6mm 6-lead package, low 20mΩ dynamic resistance, 175pF junction capacitance at 22V, and compliance with IEC 61000-4-4/4-5 surge standards.
Technical Context
The SC700HWLTRC uses a surge-rated MOSFET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events above ~27.9V breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly flat (27.5–28V) from 24A to 40A IPP due to decreasing RDS(on) under surge conditions.
It operates across –40°C to +125°C with <600nA reverse leakage at 22V, 175pF capacitance at 1MHz/22V, and 1120W peak pulse power handling - making it suitable for high-reliability input protection where thermal stability and low-voltage overshoot are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC operating voltage on protected line without leakage or degradation. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures downstream 24V-rated 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 with 2Ω source impedance. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD immunity requirements for exposed connectors. |
| Dynamic Resistance | 20mΩ - enables low-voltage overshoot and minimal power dissipation during high-current transients. |
| Junction Capacitance | 175pF at 22V/1MHz - compatible with USB PD power bus (not signal lines); requires separate low-C TVS for SS/DP/DM lanes. |
Pinout & Package
SC700HWLTRC is housed in a RoHS-compliant DFN 1.6mm × 1.6mm × 0.55mm 6-lead package with exposed thermal pad not required - energy is dissipated in the silicon FET rather than junction heating. All pins must be connected: Pins 1–3 are GND; Pins 4–6 are IN (parallel-connected for lowest inductance path).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | Ground | Low-inductance return path for surge current; all three must be tied to solid ground plane via multiple vias. |
| Pins 4, 5, 6 | Input / Protected Line | Parallel-connected anode-side terminals for EOS/ESD shunt path; placed adjacent to connector for shortest trace length. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based clamping architecture | Delivers flat 27.5–28V clamping from 24A to 40A - eliminates voltage rise with current seen in standard TVS diodes. |
| Temperature-stable clamping | Clamping voltage varies <0.5V across –40°C to +125°C - enables reliable protection in uncontrolled thermal environments. |
| High-energy surge rating | 1120W peak pulse power (8/20μs) - supports repeated lightning-surge events per IEC 61000-4-5 without parametric shift. |
| Low dynamic resistance | 20mΩ - minimizes IR drop during surge, preserving voltage margin for downstream 24V-rated components. |
| DFN 1.6×1.6mm footprint | Reduces PCB area by >50% vs. SO-8 or SOT-23 TVS solutions - ideal for space-constrained USB Type-C and IoT designs. |

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 1.6×1.6mm package, identical marking (T22XX), and same tape-and-reel packaging (3,000/reel). | No functional difference - TDS2211P.C is the official Semtech orderable part number; SC700HWLTRC is a valid distribution-level variant with identical performance. | Select TDS2211P.C when sourcing directly from Semtech or authorized distributors requiring exact manufacturer PN. |
| uClamp2411ZA | 24V working voltage, lower 20A IPP rating, higher 33V clamping, smaller 0.65×0.65mm 2-pin DFN package, and 0.25pF capacitance. | Designed for CC/SBU lines in USB-C - not suitable for VBUS/power rail protection due to lower surge rating and higher clamping. | Use uClamp2411ZA only for low-capacitance data-line protection; SC700HWLTRC remains required for high-current power-line suppression. |
Compared with TDS2211P.C (identical device) and uClamp2411ZA (data-line optimized), SC700HWLTRC provides the only validated 40A/22V solution with flat 28V clamping in a 1.6mm² footprint - making it irreplaceable for VBUS-level EOS protection where surge energy and voltage margin are non-negotiable.

FAQ
What is the primary protection function of the SC700HWLTRC?
The SC700HWLTRC functions as a transient diverting suppressor that shunts high-energy EOS events - including ESD, EFT, and lightning-induced surges - away from sensitive downstream circuitry. It uses a precision-triggered FET to achieve stable 27.5–28V clamping at up to 40A (8/20μs), protecting 22V-rated power buses such as USB-C VBUS. Its design eliminates the voltage-rise-with-current limitation of traditional TVS diodes.
Does the SC700HWLTRC require a thermal pad on the PCB?
No, the SC700HWLTRC does not require a thermal pad. Unlike TVS diodes that dissipate surge energy in the PN junction, this device channels transient current through a low-RDS(on) FET, minimizing localized heating. The datasheet explicitly states "no thermal pad is needed" - instead, robust grounding via Pins 1–3 and short, wide traces to the connector are essential for optimal surge performance.
Can the SC700HWLTRC be used on USB-C SuperSpeed differential pairs?
No, the SC700HWLTRC is not suitable for USB-C SuperSpeed (TX/RX) or DisplayPort/USB2.0 (DP/DM) lines. Its 175pF junction capacitance would severely degrade signal integrity. For those lines, Semtech specifies low-capacitance TVS devices like RClamp3371ZC (<0.25pF). The SC700HWLTRC is intended exclusively for VBUS, CC, or SBU power-rail protection - not high-speed data paths.
What is the meaning of "T22" marking on the SC700HWLTRC package?
The "T22" marking on the SC700HWLTRC indicates its product family and working voltage: "T" denotes the Transient Diverting Suppressor series, and "22" specifies the 22V reverse stand-off voltage (VRWM). This matches the electrical specification in the datasheet and distinguishes it from variants like TDS1211P (12V) or TDS3311P (33V). The two-digit date code follows "T22" on the top surface.
How does the SC700HWLTRC compare to standard TVS diodes in temperature performance?
The SC700HWLTRC maintains clamping voltage within 27.5–28V from –40°C to +125°C, whereas conventional TVS diodes exhibit significant clamping rise with temperature - e.g., +10–15V increase at 125°C. This stability stems from its FET-based architecture: clamping is governed by the trigger circuit's breakdown voltage (~27.9V), not junction characteristics. As a result, SC700HWLTRC guarantees consistent protection margins across full industrial temperature ranges.
