Product details
Overview
TS14002-C015DFNR from Semtech is a transient diverting suppressor designed for high-energy EOS protection of 22V-rated power or I/O lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.6V clamping at 40A, and 20mΩ dynamic resistance - deployed in USB Type-C PD input protection and industrial load switch front-end circuits.
For engineers reviewing the TS14002-C015DFNR datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (DFN 1.6×1.6×0.55mm, 6-lead), confirmed clamping stability across temperature, real-world USB PD and load switch use cases, and two validated alternative parts with documented parameter and application differences.
Technical Context
The TS14002-C015DFNR 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 (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 junction capacitance at 22V/1MHz, and maintains stable clamping across temperature - unlike standard TVS devices whose VC rises with both IPP and ambient temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC bus voltage it can protect without leakage or degradation. |
| Clamping Voltage | 27.6V at 40A (8/20μs) - ensures protected ICs (e.g., USB PD controllers) remain below damage threshold during worst-case surges. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD robustness requirements. |
| Dynamic Resistance | 20mΩ - enables low-voltage clamping independent of surge magnitude, critical for precision rail protection. |
| Junction Capacitance | 175pF at 22V/1MHz - compatible with medium-speed interfaces (e.g., USB 2.0, CC/SBU, load switch enable lines). |
Pinout & Package
TS14002-C015DFNR is housed in a RoHS-compliant DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no internal thermal pad required; energy dissipated in silicon). All six terminals must be connected per layout guidelines to achieve rated 40A surge performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current; all three pins must be vias-connected to inner ground plane to minimize inductance. |
| 4, 5, 6 | IN | Parallel-connected input terminals for protected line (e.g., VBUS); all three must be tied together externally to maximize current sharing and surge handling. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies only ±0.5V from 24A to 40A - eliminates design margin inflation needed with traditional TVS diodes. |
| Temperature-stable protection | Clamping remains ~27.6V from –40°C to +125°C - removes thermal derating calculations for industrial deployments. |
| Low dynamic resistance | 20mΩ enables sub-1V voltage rise across device during 40A surge - preserves system-level voltage integrity. |
| High-energy EOS suppression | Rated for 1120W peak pulse power (8/20μs) - protects against lightning-induced surges and long-duration transients. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting VBUS lines in USB-C receptacles supporting up to 20V/5A PD negotiation, exposed to ESD and cable-borne surges. IC Role / Device Role / Timing Role: Primary front-end EOS suppressor placed between connector and PD controller or load switch. Use Value: Maintains 27.6V clamping at full 40A surge - prevents overvoltage damage to sensitive PD controllers operating at 22V max rating. |
Use Scenario: Front-end protection for industrial-grade load switches (e.g., HS2950P) powering sensors, actuators, or remote meters. IC Role / Device Role / Timing Role: Surge shunt element limiting transient voltage across load switch FET drain-source terminals. Use Value: Keeps clamping below MOSFET avalanche threshold, preventing gate oxide stress and ensuring reliable hot-swap operation. |
| IoT Edge Node Power Bus Protection | Notebook/Tablet VBUS Line Protection |
Use Scenario: Securing 22V-capable power rails in battery-backed IoT gateways or edge controllers subject to field ESD and induced surges. IC Role / Device Role / Timing Role: Single-device solution replacing multi-stage TVS+MOV networks in space-constrained modules. Use Value: 1.6×1.6mm footprint saves >60% board area vs. discrete TVS+capacitor solutions while delivering higher surge rating. |
Use Scenario: Protecting main VBUS input in ultraportable notebooks and tablets where thermal and layout constraints limit protection options. IC Role / Device Role / Timing Role: Low-capacitance, high-reliability clamp integrated near USB-C port to meet OEM ESD certification requirements. Use Value: ±30kV ESD rating and stable clamping ensure pass/fail compliance across production units without binning or margin tuning. |
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 - direct form-fit-function replacement. | Same USB PD, load switch, and industrial bus use cases; validated in Semtech reference designs. | Select TDS2211P when sourcing from Semtech-authorized channels with full traceability and lifecycle support. |
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.5V VC @ 24.7A; higher clamping, no constant-clamp behavior, 100pF capacitance. | Suitable for cost-sensitive, non-critical 22V lines where 35.5V clamping is acceptable and temperature stability is secondary. | Choose SMAJ22A only if clamping voltage margin allows >8V headroom and thermal derating is acceptable. |
Compared with TDS2211P and SMAJ22A, TS14002-C015DFNR delivers identical protection performance to TDS2211P but may differ in date-code marking or reel packaging; versus SMAJ22A, it provides 8V lower clamping and eliminates temperature-dependent derating - critical for compact, thermally constrained USB PD and industrial systems.

FAQ
What is the exact package type and dimensions of TS14002-C015DFNR?
TS14002-C015DFNR uses a DFN package measuring 1.6mm × 1.6mm × 0.55mm with 6 leads. Pin 1 is marked by a laser dot; terminals 1–3 are GND, and 4–6 are IN. The package is Pb-free, halogen-free, and RoHS/WEEE compliant with UL 94V-0 molding compound.
Does TS14002-C015DFNR require a thermal pad on the PCB?
No - TS14002-C015DFNR does not require an exposed thermal pad. Its energy dissipation occurs within the silicon die during transient events, and the datasheet explicitly states "no thermal pad is needed." Layout focuses instead on low-inductance GND vias and short, wide traces to pins 1–3 and 4–6.
How does TS14002-C015DFNR achieve constant clamping voltage across surge current?
TS14002-C015DFNR uses a surge-rated FET as its protection element, triggered by a precision circuit. As surge current increases, the FET's RDS(on) decreases, counteracting voltage rise - resulting in clamping voltage that stays within 27.5–28V from 24A to 40A, unlike TVS diodes whose VC rises linearly with current.
Can TS14002-C015DFNR be used on USB 3.2 SuperSpeed differential pairs?
No - TS14002-C015DFNR is not suitable for USB 3.2 SuperSpeed (TX/RX) lines. Its 175pF junction capacitance would severely degrade signal integrity. For those lines, Semtech recommends low-capacitance TVS devices like RClamp3371ZC (<0.25pF), while TS14002-C015DFNR is intended for VBUS, CC, SBU, or load switch enable inputs.
What is the maximum operating temperature range for TS14002-C015DFNR?
TS14002-C015DFNR is rated for continuous operation from –40°C to +125°C. Its clamping voltage remains stable across this full range, and its junction temperature can reach +150°C during transient events - making it suitable for under-hood automotive accessories and industrial control cabinets.
