Product details
Overview
TS14002-C012DFNR 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 in space-constrained industrial and portable devices.
For engineers reviewing the TS14002-C012DFNR 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 compatibility with ±1kV IEC 61000-4-5 surge testing on unsymmetrical lines.
Technical Context
The TS14002-C012DFNR uses a surge-rated FET as the primary protection element, activated by a precision trigger circuit when transient voltage exceeds breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly constant (27.5–28V) from 24A to 40A due to decreasing RDS(on) under surge conditions.
It operates over –40°C to +125°C with <600nA reverse leakage at 22V, 175pF capacitance at 1MHz/22V, and 1120W peak pulse power handling. The device protects one line with bidirectional capability and requires all six pins connected - three GND (pins 1–3) and three IN (pins 4–6) - for full 40A rating.
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 degradation. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave, RS=2Ω) - ensures downstream ICs (e.g., USB PD controllers) remain below damage threshold during surge. |
| Peak Pulse Current | 40A (8/20μs) - supports compliance with IEC 61000-4-5 Level 4 industrial surge immunity requirements. |
| ESD Withstand | ±30kV contact & air per IEC 61000-4-2 - exceeds automotive and industrial ESD immunity standards for connector-facing protection. |
| Dynamic Resistance | 20mΩ - enables flat clamping response and minimizes voltage overshoot during fast-rising transients. |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for USB PD VBUS protection without signal integrity impact on DC/low-frequency power lines. |
Pinout & Package
TS14002-C012DFNR is housed in a RoHS-compliant DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad not required (energy dissipated in silicon). All six terminals must be soldered for rated performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected to minimize inductance and achieve full 40A rating. |
| Pins 4, 5, 6 | IN | Protected line input (bidirectional); connects directly to VBUS or power/data line requiring 22V EOS protection. |
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 concerns in thermally demanding environments. |
| Low dynamic resistance | 20mΩ enables sub-1V voltage rise across device during 40A surge - critical for protecting low-voltage-tolerant load switches and e-fuses. |
| High-energy surge rating | 1120W peak pulse power (8/20μs) supports repeated lightning-surge events without parametric shift or failure. |
| Ultra-low leakage | <600nA at 22V ensures minimal standby power loss in battery-powered IoT and portable 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, exposed to ESD and system-level surges. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed adjacent to connector, diverting transients before they reach PD controller or multiplexer. Use Value: Maintains 28V clamping at full 40A even at 125°C - prevents false overvoltage shutdown and avoids over-spec'ing TVS devices. |
Use Scenario: Safeguarding input 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 that limits voltage stress on internal FET gate oxide and drain-source junction during lightning-induced surges. Use Value: 20mΩ RDYN ensures <0.8V additional drop during 40A surge - keeps switch VDS within safe SOA and avoids latch-up. |
| IoT Device Power Rail Protection | Storage Device 22V Backup Supply Protection |
|
Use Scenario: Securing 22V auxiliary rails in battery-backed smart sensors and edge nodes subjected to field ESD and induced surges. IC Role / Device Role / Timing Role: Single-component solution replacing multi-stage TVS+MOV designs, reducing BOM count and PCB area by >50%. Use Value: 1.6×1.6mm DFN footprint saves board space vs. SOT-23 or SOIC alternatives while delivering superior clamping stability. |
Use Scenario: Protecting 22V backup power inputs in NVMe SSDs and enterprise storage controllers against hot-plug transients and ESD. IC Role / Device Role / Timing Role: High-reliability clamp positioned between connector and DC-DC converter input, ensuring clean startup after surge events. Use Value: 175pF capacitance avoids resonance with typical input filter inductors - maintains stable regulation without oscillation risk. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Identical electrical specs, same DFN 1.6×1.6mm package, identical pinout and marking (T22 code), manufactured by Semtech - direct form-fit-function replacement. | No functional difference; used interchangeably in USB PD, load switch, and industrial power rail designs. | Select TS14002-C012DFNR for Aetrix-sourced traceability and volume procurement support; TDS2211P remains valid for legacy BOMs. |
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.5V VC @ 12.3A (8/20μs), higher clamping, no constant-clamp behavior, larger SMA package. | Limited to lower-energy surges; clamping rises with temperature and current - unsuitable for 40A or high-temp industrial use. | Only consider SMAJ22A where cost is primary and surge energy is ≤12A; avoid where stable clamping or compact layout is required. |
Compared with TDS2211P, TS14002-C012DFNR offers identical protection performance with enhanced supply chain control; versus SMAJ22A, it delivers 30% lower clamping voltage, 3.3× higher surge current rating, and 75% smaller footprint - making it optimal for next-gen USB PD and space-constrained industrial power rails.

FAQ
What is the maximum continuous operating voltage for TS14002-C012DFNR?
The TS14002-C012DFNR has a reverse stand-off voltage (VRWM) of 22V, meaning it can continuously withstand up to 22V DC or RMS on the protected line without significant leakage or degradation. This makes it ideal for 20V USB PD VBUS and other 22V-rated industrial power rails.
Does TS14002-C012DFNR require a thermal pad on the PCB?
No, TS14002-C012DFNR does not require a thermal pad. Its DFN 1.6×1.6mm package dissipates surge energy internally via the silicon FET structure, not through conduction to the board. Layout guidelines emphasize low-inductance grounding (multiple vias to inner ground planes) rather than thermal relief.
Can TS14002-C012DFNR protect bidirectional signal lines like USB CC or DP/DM?
No - TS14002-C012DFNR is optimized for unidirectional or bidirectional power-line protection (e.g., VBUS, load switch inputs), not high-speed data lines. Its 175pF capacitance would impair signal integrity on SuperSpeed or DisplayPort lanes; low-capacitance TVS devices like RClamp3371ZC are recommended for those paths.
How does TS14002-C012DFNR's clamping performance compare to standard TVS diodes at elevated temperature?
Unlike standard TVS diodes whose clamping voltage increases with temperature, TS14002-C012DFNR maintains a stable 27.5–28V clamping voltage from –40°C to +125°C. This is confirmed in its datasheet's "Clamping Voltage vs. Temperature" plot and stems from its FET-based architecture with near-zero temperature coefficient for RDS(on).
Is TS14002-C012DFNR pin-compatible with TDS2211P?
Yes - TS14002-C012DFNR shares identical pin configuration (GND on pins 1–3, IN on pins 4–6), mechanical dimensions (1.6×1.6×0.55mm DFN), and electrical specifications with TDS2211P. It is a direct, drop-in replacement with identical marking (T22 code) and tape-and-reel packaging (3,000 pcs/reel).
