Product details
Overview
SC600BIMSTRT from Semtech is a Transient Diverting Suppressor (TDS) designed for high-energy EOS/ESD 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 protection in USB PD, Type-C, and industrial load-switch inputs.
For engineers reviewing the SC600BIMSTRT datasheet, pinout, applications, or equivalent options, this device offers critical advantages over conventional TVS diodes: near-constant clamping voltage independent of surge current or temperature, ultra-low dynamic resistance (20 mΩ), and DFN 1.6×1.6mm footprint optimized for space-constrained high-voltage interfaces.
Technical Context
The SC600BIMSTRT uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events. Unlike standard 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 <600 nA reverse leakage at 22V, 175 pF junction capacitance at 22V/1MHz, and is rated for 1120W peak pulse power. The device protects one line (IN-to-GND), with all three IN pins (4–6) and all three GND pins (1–3) required for full 40A capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22 V - matches nominal USB PD bus and industrial 24V rail systems without derating. |
| Clamping Voltage | 27.5–28 V at 40A (8/20μs) - stays within safe margin below typical 30V+ IC damage thresholds. |
| Peak Pulse Current | 40 A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity requirements for industrial equipment. |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - exceeds automotive and consumer ESD robustness standards. |
| Dynamic Resistance | 20 mΩ - enables low-voltage overshoot during fast transients, minimizing stress on downstream FETs. |
| Junction Capacitance | 175 pF at 22V/1MHz - suitable for DC power and low-speed signal lines (e.g., CC, SBU, VBus), not high-speed data lanes. |
| Package | DFN 1.6 mm × 1.6 mm × 0.55 mm, 6-lead - saves >50% board area vs. SO-8 or SOT-23 TVS alternatives. |
Pinout & Package
SC600BIMSTRT is housed in a Pb-free, RoHS-compliant DFN 1.6 mm × 1.6 mm × 0.55 mm package with exposed thermal pad (no solder connection required). All six terminals are surface-mount; pin 1 is marked by laser dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path - all three must be connected with low-inductance vias to maximize 40A surge current handling. |
| 4, 5, 6 | IN | Protected line input - tied together to distribute surge current across parallel bond wires and minimize trace inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5 V across 24–40A IPP and –40°C to +125°C - eliminates thermal derating design iterations. |
| FET-based shunt topology | Replaces avalanche diode junction with low-RDS(on) MOSFET - dissipates energy in channel rather than PN junction, improving reliability under repeated surges. |
| High EFT immunity | ±4 kV per IEC 61000-4-4 (5/50 ns, 100 kHz/5 kHz) - protects against burst noise in motor drives and PLC I/O modules. |
| Low-leakage operation | ≤600 nA at 22 V - avoids quiescent current penalties in battery-backed or always-on IoT sensor nodes. |
| UL 94V-0 molding compound | Flame-retardant encapsulation - satisfies safety compliance for industrial and medical end-equipment. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting VBus lines in USB-C ports supporting up to 20V/5A PD negotiation, exposed to ESD from hot-plug and lightning-induced surges. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed between connector and PD controller or load switch - responds within nanoseconds to divert transients before damage occurs. Use Value: Maintains 27.5–28V clamping across temperature, preventing false overvoltage trips and ensuring PD controller survival where conventional TVS would exceed 35V at 125°C. |
Use Scenario: Safeguarding input terminals of industrial-grade load switches (e.g., HS2950P) in remote meters, robotics, and factory automation systems. IC Role / Device Role / Timing Role: Front-end transient suppressor - clamps surges before they reach the internal FET gate oxide or current-sense circuitry of the load switch. Use Value: Enables use of cost-optimized load switches rated only to 30V by holding clamp voltage safely below their absolute maximum ratings, even at full 40A surge. |
| IoT Edge Node Power Bus Protection | Storage Device 22V Rail Protection |
|
Use Scenario: Securing 22V auxiliary rails in battery-powered gateways or edge AI sensors subjected to ESD during field servicing and EFT in noisy factory environments. IC Role / Device Role / Timing Role: Standalone transient diverter on main power input - operates independently of system MCU or PMIC, requiring no enable signals or configuration. Use Value: Delivers 40A surge handling in 1.6×1.6mm footprint - allows compact, sealed enclosures without sacrificing surge immunity or adding heatsinking. |
Use Scenario: Protecting 22V backup or auxiliary supplies in NVMe SSDs, SAS expanders, and enterprise HDD backplanes exposed to hot-swap and system-level surges. IC Role / Device Role / Timing Role: DC rail protector - placed upstream of LDOs or buck converters to prevent transient-induced latch-up or regulator failure. Use Value: Low 175 pF capacitance avoids destabilizing switching regulators; stable clamping ensures downstream power integrity during 1.2/50μs combination-wave tests. |
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; SC600BIMSTRT is a valid branded variant used by select distributors. | Select TDS2211P.C when sourcing directly from Semtech or authorized channels requiring full traceability and standard part numbering. |
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.5V VC @ 12.3A; higher clamping (≥40V at 40A), no constant-clamp behavior, 10× higher dynamic resistance (~200 mΩ). | Limited to lower-energy surges; unsuitable for sustained 40A or high-temperature operation where clamping voltage drift exceeds safe margins. | Choose SMAJ22A only for cost-sensitive, non-critical 22V lines where 40A surge rating and temperature stability are not required. |
Compared with TDS2211P.C (identical function and form) and SMAJ22A (conventional TVS), SC600BIMSTRT provides superior surge resilience through flat clamping and FET-based energy handling - making it essential for USB PD, industrial load switches, and any 22V system where reliability under repeated or high-temperature transients is mandatory.

FAQ
What is the exact package type and dimensions of SC600BIMSTRT?
SC600BIMSTRT uses a DFN (Dual Flat No-lead) package measuring 1.6 mm × 1.6 mm × 0.55 mm with 6 leads. Pin 1 is marked by a laser dot; the package is Pb-free, halogen-free, RoHS/WEEE compliant, and UL 94V-0 rated. Its land pattern requires symmetric copper pour and multiple vias under GND pins (1–3) for optimal surge current handling.
Does SC600BIMSTRT require external biasing or control signals to operate?
No, SC600BIMSTRT is fully passive and autonomous - it requires no enable pin, supply voltage, or configuration. The internal trigger circuit activates the shunt FET automatically when input voltage exceeds ~25V (VBR). This makes SC600BIMSTRT ideal for fail-safe protection in always-on or low-power systems without added complexity.
How does SC600BIMSTRT's clamping voltage compare to standard TVS diodes at elevated temperatures?
Unlike standard TVS diodes whose clamping voltage rises significantly with temperature (e.g., +10–15V increase from –40°C to +125°C), SC600BIMSTRT maintains 27.5–28V clamping across –40°C to +125°C. This stability is confirmed in Figure 4 of the datasheet and eliminates thermal derating calculations during design validation.
Can SC600BIMSTRT protect high-speed data lines like USB SuperSpeed or PCIe?
No - SC600BIMSTRT has 175 pF junction capacitance at 22V, which is too high for USB 3.x (≤0.3 pF required) or PCIe lanes. It is intended exclusively for DC power rails (VBus, 22V aux), CC/SBU, DP/DM, or low-speed control lines. For high-speed data, Semtech recommends RClamp3371ZC (<0.25 pF) alongside SC600BIMSTRT in full USB-C solutions.
Is SC600BIMSTRT pin-compatible with other Semtech TDS devices like TDS3301P or TDS5801P?
No - SC600BIMSTRT (TDS2211P) uses a 6-pin DFN with 3-IN / 3-GND configuration. TDS3301P is a 5-pin DFN (1-IN / 1-GND / 3-NC), and TDS5801P is an 8-pin DFN with different pin mapping and dual-line capability. Each TDS family member has unique pinout, voltage rating, and surge rating - direct substitution is not supported.
