Product details
Overview
TS14002-C020DFNR 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. It is deployed in USB Type-C PD input protection where low, flat clamping prevents damage to downstream controllers.
For engineers reviewing the TS14002-C020DFNR datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability over 40A surge current, DFN-6 thermal and layout performance, 22V working voltage compliance, and compatibility with industrial surge standards (±1kV, 1.2/50μs).
Technical Context
The TS14002-C020DFNR 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 due to decreasing RDS(on) under surge - not fixed dynamic resistance.
It operates across –40°C to +125°C with <20mΩ dynamic resistance (8/20μs), 175pF junction capacitance at 22V/1MHz, and <600nA reverse leakage. Its functional architecture enables reliable protection in high-voltage USB PD and load switch inputs without thermal derating penalties.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD bus voltage and ensures no leakage or conduction during normal operation. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - stays flat across full surge range, protecting 30V-tolerant ICs without margin erosion. |
| ESD Rating | ±30kV contact & air (IEC 61000-4-2) - exceeds industrial and consumer ESD immunity requirements. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment interfaces. |
| Junction Capacitance | 175pF at 22V/1MHz - low enough for 22V power rail protection without signal integrity impact. |
| Dynamic Resistance | 20mΩ (8/20μs) - enables low-voltage drop during surge, minimizing energy dissipation in the device. |
| Package | DFN 1.6×1.6×0.55mm, 6-lead - ultra-compact footprint with three parallel input and three ground terminals for low-inductance layout. |
Pinout & Package
TS14002-C020DFNR is housed in a Pb-free, RoHS-compliant DFN-6 package (1.6 mm × 1.6 mm × 0.55 mm) with exposed thermal pad not required - energy is dissipated in the FET channel, not the junction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path; all three must be connected to minimize inductance and maximize 40A surge handling. |
| Pins 4, 5, 6 | IN | Parallel-connected input terminals for protected line (e.g., VBUS); equal current sharing reduces per-pin stress and thermal rise. |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping voltage | 27.5–28V across 24–40A surge range and –40°C to +125°C - eliminates design uncertainty from temperature- or current-dependent voltage rise. |
| FET-based shunt architecture | Replaces PN-junction TVS with low-RDS(on) MOSFET - avoids junction heating and enables higher surge endurance without derating. |
| Low dynamic resistance | 20mΩ - reduces clamping overshoot and improves energy diversion efficiency vs. typical TVS (>1Ω). |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz) - protects against repetitive fast transients in motor drives and industrial comms. |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting VBUS lines in USB-C receptacles supporting up to 20V/5A PD negotiation. IC Role / Device Role / Timing Role: Primary EOS suppressor placed between connector and PD controller or load switch. Use Value: Maintains 27.5V clamping at 40A and 125°C - prevents latch-up or gate oxide damage in PD controllers rated ≤30V. |
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 shunt that limits voltage seen by internal FET gate oxide and sense circuitry. Use Value: Clamps below 28V regardless of ambient temperature - avoids overvoltage failure modes common with TVS-based solutions. |
| IoT Edge Node Power Bus Protection | Storage Device 22V Rail Protection |
Use Scenario: Securing 22V auxiliary rails in battery-backed IoT gateways exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Single-device solution for IEC 61000-4-5 Level 4 (±1kV, RS=42Ω) compliance on compact PCBs. Use Value: Delivers 40A surge capability in 1.6×1.6mm footprint - replaces larger multi-chip TVS arrays while improving reliability. |
Use Scenario: Protecting 22V DC-DC outputs feeding NVMe SSD power management ICs in enterprise storage enclosures. IC Role / Device Role / Timing Role: High-energy clamping element placed directly at power entry point before bulk capacitance. Use Value: 175pF capacitance avoids resonance with downstream LC filters; stable clamping preserves PMIC reset thresholds. |
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-6 package, identical marking code T22 - confirmed pin-to-pin and functionally equivalent replacement. | No change in layout, BOM, or test plan required; validated for USB-C PD and load switch use cases. | Select when direct Semtech second-source assurance or alternate date-code availability is needed. |
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.5V VC @ 12.3A - higher clamping, no current-flatness, 10× higher dynamic resistance (~200mΩ). | Requires higher surge rating (e.g., 60A part) to achieve comparable clamping, increasing board area and cost. | Acceptable only if clamping >35V is tolerable and temperature stability is not critical. |
Compared with TDS2211P, TS14002-C020DFNR offers identical performance and form factor - enabling seamless substitution. Against SMAJ22A, TS14002-C020DFNR provides 8V lower clamping at full surge, stable voltage over temperature, and 10× lower dynamic resistance - critical for protecting modern 30V-tolerant power ICs.

FAQ
What is the clamping voltage behavior of TS14002-C020DFNR under varying surge current?
The TS14002-C020DFNR maintains a tightly bounded clamping voltage of 27.5–28V across its full rated peak pulse current range (24A to 40A, 8/20μs). This flat response results from its FET-based shunt architecture, where RDS(on) decreases under surge - unlike TVS diodes whose clamping rises linearly with current. The TS14002-C020DFNR datasheet confirms this behavior is guaranteed across –40°C to +125°C.
Is TS14002-C020DFNR pin-compatible with TDS2211P?
Yes, TS14002-C020DFNR is pin-to-pin and functionally identical to TDS2211P: both use the same DFN-6 (1.6×1.6mm) package with pins 1–3 as GND and pins 4–6 as IN. Marking code "T22" and electrical specifications including 22V working voltage, 40A surge rating, and 27.5–28V clamping match exactly. TS14002-C020DFNR serves as a direct, drop-in replacement.
Can TS14002-C020DFNR protect USB Type-C CC lines?
No - TS14002-C020DFNR is designed for 22V power or high-current I/O lines (e.g., VBUS), not low-voltage, high-speed data lines like CC or SBU. Its 175pF capacitance would disrupt CC signaling. For CC/SBU protection, Semtech recommends uClamp2411ZA (24V, <10pF). TS14002-C020DFNR is intended for the main power rail, not sideband or differential pairs.
Does TS14002-C020DFNR require a thermal pad or heatsink?
No. TS14002-C020DFNR dissipates surge energy in the FET channel, not the silicon junction, so no thermal pad or external heatsink is needed. The DFN-6 package relies on low-inductance PCB layout - connecting all three GND pins (1,2,3) and all three IN pins (4,5,6) with short, wide traces and multiple vias to inner ground planes - to handle 40A surges safely.
What surge standards does TS14002-C020DFNR meet?
TS14002-C020DFNR meets IEC 61000-4-2 (±30kV ESD), IEC 61000-4-4 (±4kV EFT), and IEC 61000-4-5 (40A, 8/20μs; ±1kV, 1.2/50μs with 42Ω source). Its 27.5–28V clamping at 40A satisfies Level 4 industrial surge immunity requirements. It is not rated for AC mains or telecom lightning standards (e.g., ITU-T K.20/K.44), which demand higher energy handling.
