Product details
Overview
SC32300BULTRC 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 PD and Type-C bus protection.
For engineers reviewing the SC32300BULTRC 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 61000-4-4/5 standards.
Technical Context
The SC32300BULTRC uses a surge-rated MOSFET as its primary protection element, activated by a precision trigger circuit when transient voltage exceeds breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly constant - independent of peak pulse current (24A to 40A) and operating temperature (−40°C to +125°C).
This behavior stems from the FET's decreasing RDS(on) under surge conditions, yielding ultra-low dynamic resistance (20mΩ) and eliminating the linear VC = VBR + IPP × RDYN dependency seen in junction-based TVS devices. The device protects one bidirectional line between pins 4–6 (IN) and pins 1–3 (GND).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC or RMS operating voltage on protected line without leakage or conduction. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo waveform) - 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 for 22V systems. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds Level 4 ESD immunity for external connectors and user-accessible ports. |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for USB PD VBUS line protection without signal integrity impact on DC/low-frequency power rails. |
| Dynamic Resistance | 20mΩ - enables flat clamping response and minimizes voltage overshoot during fast-rising transients. |
Pinout & Package
SC32300BULTRC is housed in a Pb-free, RoHS-compliant DFN package measuring 1.6mm × 1.6mm × 0.55mm with 6 leads and UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected to maximize current-handling capability and minimize parasitic inductance. |
| Pins 4, 5, 6 | IN | Protected line input (bidirectional); connects directly to VBUS or I/O line requiring 22V EOS protection - all three pins conduct surge current in parallel. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp FET architecture | Clamping voltage stays within 27.5–28V from 24A to 40A and −40°C to +125°C - eliminates derating uncertainty in thermal or high-current designs. |
| High-energy surge handling | 1120W peak pulse power (8/20μs) supports industrial-grade lightning and load-dump protection without thermal runaway. |
| Low dynamic resistance | 20mΩ measured between 1A–40A enables minimal IR drop during surge, preserving voltage margin for downstream 24V logic or power switches. |
| Ultra-low leakage | ≤600nA at 22V reverse bias - prevents measurable power loss or voltage droop in always-on 22V power rail applications. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V VBUS lines in USB-C receptacles against ESD, lightning-induced surges, and hot-plug transients. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed adjacent to connector, diverting >40A transients to GND before reaching PD controller or e-fuse. Use Value: Maintains 28V clamping at full 40A and 125°C - avoids overvoltage damage to 24V-rated USB PD controllers where conventional TVS would exceed 38V. |
Use Scenario: Safeguarding input terminals of industrial load switches (e.g., HS2950P) exposed to field wiring transients in remote meters or robotics. IC Role / Device Role / Timing Role: Front-end transient clamp limiting voltage stress on internal switch FET gate oxide and drain-source junction. Use Value: Prevents latch-up or permanent failure of load switches rated ≤30V by holding clamping <28V even during 8/20μs surges up to 40A. |
| IoT Device Power Rail Protection | Storage Device 22V Backup Power Line |
Use Scenario: Securing 22V auxiliary power inputs in battery-backed IoT edge nodes subject to EFT bursts and cable discharge events. IC Role / Device Role / Timing Role: Single-component, low-capacitance suppressor for DC power entry points where PCB space and thermal mass are constrained. Use Value: 175pF capacitance avoids filtering effects on 22V DC supply; ±4kV EFT immunity (IEC 61000-4-4) ensures reliable operation in electrically noisy factory environments. |
Use Scenario: Protecting 22V supercapacitor or LiFePO₄ backup power lines in enterprise SSDs or NAS enclosures against system-level surges. IC Role / Device Role / Timing Role: Bidirectional transient suppressor on non-switched backup rail, absorbing energy from shared ground bounce or board-level coupling. Use Value: Stable clamping across temperature ensures consistent protection during extended operation in heated storage chassis (up to 125°C ambient). |
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 pinout and marking (T22XX), same tape-and-reel packaging (3,000/reel). | No functional difference - TDS2211P.C is the official Semtech orderable part number corresponding to SC32300BULTRC. | Select TDS2211P.C when sourcing directly from Semtech or authorized distributors; SC32300BULTRC is a valid alternate marking used in certain logistics channels. |
| uClamp2411ZA | 24V working voltage, lower 20A IPP rating, higher 33V clamping at 20A, smaller 0.6×0.3mm 2-pin SOD-523 package, 0.25pF capacitance. | Targeted at low-capacitance data-line protection (CC/SBU), not power-line duty; unsuitable for 40A surge or 22V bus clamping. | Use uClamp2411ZA only for auxiliary signal lines; SC32300BULTRC remains required for main 22V power rail protection due to superior energy handling and stable clamping. |
Compared with TDS2211P.C (identical device) and uClamp2411ZA (lower-energy signal-line variant), SC32300BULTRC provides verified 40A/28V clamping performance in a space-efficient DFN package - making it the sole suitable choice for 22V power rail EOS protection where sustained surge energy and thermal stability are critical.

FAQ
What is the exact package type and dimensions of SC32300BULTRC?
SC32300BULTRC uses a DFN (Dual Flat No-lead) package measuring 1.6mm × 1.6mm × 0.55mm with 6 terminals. Pins 1–3 are GND; pins 4–6 are IN. The package is Pb-free, halogen-free, RoHS/WEEE compliant, and carries UL 94V-0 flammability rating. Marking code is "T22" followed by date code.
Does SC32300BULTRC support bidirectional transient protection?
Yes, SC32300BULTRC provides symmetrical bidirectional protection between its IN (pins 4–6) and GND (pins 1–3) terminals. Its design allows clamping of both positive and negative transients up to ±30kV (IEC 61000-4-2) and ±1kV (IEC 61000-4-5), making it suitable for DC power rails like USB PD VBUS.
How does SC32300BULTRC differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN), SC32300BULTRC uses a triggered FET to maintain clamping at 27.5–28V across its full 24–40A range and −40°C to +125°C operating temperature - eliminating thermal and current derating uncertainty.
Can SC32300BULTRC be used to protect USB SuperSpeed data lines?
No - SC32300BULTRC has 175pF junction capacitance, which is too high for USB 3.x/3.2 SuperSpeed differential pairs (TX/RX). For those lines, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF). SC32300BULTRC is intended exclusively for VBUS, CC, SBU, or other low-speed/high-energy lines.
What is the maximum operating temperature range for SC32300BULTRC?
SC32300BULTRC is rated for continuous operation from −40°C to +125°C ambient temperature. Its clamping voltage and leakage current remain fully specified across this range, and its junction temperature can reach +150°C per absolute maximum ratings - supporting use in thermally demanding industrial and automotive-adjacent applications.
