Product details
Overview
TS12001-C017DFNR from Semtech is a Transient Diverting Suppressor designed for high-energy EOS protection on 22V-rated power or I/O lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 40A, and 20mΩ dynamic resistance. It protects USB PD, USB Type-C VBus, and load switch inputs in industrial and portable electronics.
For engineers reviewing the TS12001-C017DFNR datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, temperature-stable clamping behavior, and direct alternatives for EOS-critical 22V bus protection.
Technical Context
The TS12001-C017DFNR uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that turns on the shunt path when transient voltage exceeds breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly constant across 24–40A (8/20μs) due to decreasing RDS(on) under surge conditions.
It operates from −40°C to +125°C with stable 27.5–28V clamping at 40A, <600nA reverse leakage at 22V, and 175pF junction capacitance at 22V/1MHz - enabling robust protection without signal integrity compromise in high-speed power interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC operating voltage of protected line without leakage or conduction. |
| 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 surge immunity for industrial equipment and USB PD input stages. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD requirements for connector-facing protection. |
| Dynamic Resistance | 20mΩ - enables low-voltage-drop shunting, minimizing power dissipation and thermal stress during multi-amp transients. |
| Junction Capacitance | 175pF at 22V/1MHz - compatible with DC power rails and low-speed control lines; not suitable for >100MHz data paths. |
Pinout & Package
TS12001-C017DFNR is housed in a RoHS-compliant DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed pad-less construction and UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return for surge current; all three must be connected to minimize inductance and maximize 40A handling. |
| Pins 4, 5, 6 | IN | Protected line input (e.g., VBus); parallel connection ensures uniform current sharing and optimal clamping performance. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V across full 24–40A surge range - eliminates design margin inflation needed with TVS diodes. |
| Temperature-stable protection | Clamping remains 27.5–28V from −40°C to +125°C - removes derating calculations required for conventional TVS devices. |
| Low dynamic resistance | 20mΩ enables efficient energy diversion with minimal self-heating - supports repeated surge events without degradation. |
| High-energy EOS rating | 1120W peak pulse power (8/20μs) - sustains protection against lightning-induced surges in industrial and outdoor equipment. |
Applications
| USB Type-C Power Delivery Bus 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 EOS shunt protector placed directly at connector, clamping transients before reaching PD controller and power switches. Use Value: Maintains 27.5–28V clamping across temperature and current - prevents false overvoltage shutdown and ensures PD compliance under real-world surge conditions. |
Use Scenario: Safeguarding enable and input pins of high-side load switches (e.g., HS2950P) in remote meters and robotics. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage seen by internal FET gate oxide and drain-source junction. Use Value: Prevents permanent latch-up or gate rupture in load switches during 1kV/42Ω surges - extends field reliability without adding external series impedance. |
| IoT Device DC Power Rail Protection | Notebook/Tablet Main Power Input Protection |
Use Scenario: Securing 12–24V DC input rails in battery-powered IoT gateways exposed to ESD during field servicing. IC Role / Device Role / Timing Role: Single-component solution replacing multi-stage TVS+MOV networks for compact, low-BOM-count designs. Use Value: Delivers ±30kV ESD immunity in 1.6mm² footprint - reduces PCB area by >60% versus discrete TVS+capacitor solutions. |
Use Scenario: Hardening 20V system power inputs in ultrabooks and tablets against accidental AC adapter surges and connector hot-plug transients. IC Role / Device Role / Timing Role: Fast-acting shunt suppressor positioned between barrel jack/USB-C port and main PMIC input. Use Value: Limits clamping overshoot to ≤28V at full 40A - avoids brownout or reset events in sensitive SoC power domains during surge recovery. |
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 DFN-6 package - confirmed drop-in replacement per Semtech documentation. | No functional or layout change required; validated for USB PD, load switch, and industrial 22V rail use cases. | Select TS12001-C017DFNR when requiring Semtech's branded, traceable production lot with extended lifecycle support. |
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.5V VC @ 12.3A - higher clamping, lower IPP, no temperature stability. | Requires larger derating margin for 40A surges; unsuitable where clamping must stay ≤28V across temperature. | Use only in cost-sensitive, non-critical 22V lines where 35.5V clamping is acceptable and surge duty is infrequent. |
Compared with TDS2211P, TS12001-C017DFNR offers identical performance and sourcing continuity; versus SMAJ22A, it delivers 8.5V lower clamping at full surge current and stable operation from −40°C to +125°C - critical for USB PD and industrial load switch reliability.

FAQ
What is the exact package type and dimensions of TS12001-C017DFNR?
TS12001-C017DFNR 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 follows Semtech's recommended layout with multiple vias to ground plane for low-inductance surge return.
Does TS12001-C017DFNR meet IEC 61000-4-5 surge immunity standards?
Yes, TS12001-C017DFNR is rated for 40A peak pulse current (8/20μs) and ±1kV (1.2/50μs, RS = 42Ω) per IEC 61000-4-5, making it suitable for Level 4 industrial surge protection. Its 27.5–28V clamping ensures protected ICs remain within safe operating voltage during full-rated surge events.
How does TS12001-C017DFNR differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with current (VC = VBR + IPP × RDYN), TS12001-C017DFNR maintains near-constant 27.5–28V clamping from 24A to 40A due to its FET-based shunt architecture and decreasing RDS(on). This eliminates need for oversized derating margins in design.
Can TS12001-C017DFNR be used on high-speed data lines like USB SuperSpeed?
No, TS12001-C017DFNR is not suitable for high-speed data lines. With 175pF junction capacitance at 22V, it would severely degrade signal integrity on >100MHz differential pairs. It is intended exclusively for DC power rails and low-speed control lines such as USB PD VBus, CC, or load switch enable inputs.
What is the maximum operating temperature range for TS12001-C017DFNR?
TS12001-C017DFNR is specified for continuous operation from −40°C to +125°C. Its clamping voltage remains stable across this full range - unlike TVS diodes, which exhibit rising VC and falling IPP capability as temperature increases - ensuring consistent protection in automotive under-hood or industrial ambient environments.
