Product details
Overview
SMDA15CN-5.TBT from Semtech is a Transient Diverting Suppressor (TDS) designed for high-energy EOS protection of 22V-rated I/O or power lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 24–40A, and 20mΩ dynamic resistance - deployed in USB Type-C PD input protection and industrial load switch front-end circuits.
For engineers reviewing the SMDA15CN-5.TBT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature and current, low dynamic resistance for minimal voltage overshoot, DFN-6 package layout compatibility, and compliance with IEC 61000-4-2/4-4/4-5 surge standards.
Technical Context
The SMDA15CN-5.TBT 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, maintains stable 175pF junction capacitance at 22V/1MHz, exhibits ≤600nA reverse leakage at VRWM, and delivers 1120W peak pulse power handling - all enabled by solid-state architecture and UL 94V-0 molding compound in a 1.6mm × 1.6mm × 0.55mm DFN package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC bus voltage before activation; matches USB PD 20V nominal + margin. |
| Clamping Voltage | 27.5–28V at 24–40A (1.2/50μs + 8/20μs combo wave, RS = 2Ω) - ensures protected ICs (e.g., USB PD controllers) remain below damage threshold. |
| 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 common system-level ESD test requirements for end-equipment certification. |
| Dynamic Resistance | 20mΩ (measured 1–40A, 8/20μs) - enables flat clamping response and minimizes voltage rise during fast transients. |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for <22V power rail protection without signal integrity impact on adjacent traces. |
| Package | DFN 1.6mm × 1.6mm × 0.55mm, 6-lead - enables compact placement near connectors with minimal PCB area (2.56 mm² footprint). |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, Pb-free, RoHS/WEEE compliant, UL 94V-0 molding compound, tape-and-reel packaging (3,000 pcs/reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground terminals - all three must be connected to low-inductance ground plane via multiple vias for full 40A surge current path. |
| 4, 5, 6 | IN | Protected line input - pins tied together to interface with single 22V bus (e.g., VBUS in USB-C); no internal series impedance. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies <0.5V across 24–40A and −40°C to +125°C - eliminates derating uncertainty vs. traditional TVS diodes. |
| FET-based shunt topology | Surge energy dissipated in low-RDS(on) channel instead of PN junction - enables higher IPP and better thermal stability. |
| Low dynamic resistance | 20mΩ measured over full surge range - reduces overshoot during fast-rising transients (e.g., ESD) and improves system robustness. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 100kHz/5kHz bursts) - protects against repetitive switching noise in industrial motor drives and PLCs. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting VBUS line in USB-C receptacles supporting up to 20V/5A PD profiles against lightning surges and connector hot-plug transients. IC Role / Device Role / Timing Role: Primary front-end EOS suppressor placed between connector and USB PD controller or load switch. Use Value: Maintains 27.5–28V clamping across temperature and current - prevents overvoltage damage to PD controllers rated ≤30V absolute max. |
Use Scenario: Front-end protection for industrial-grade load switches (e.g., HS2950P) exposed to 42Ω-coupled ±1kV surges per IEC 61000-4-5. IC Role / Device Role / Timing Role: Shunt protector limiting voltage stress on internal FET gate oxide and drain-source junction during surge events. Use Value: Clamps below 28V while handling 40A - keeps load switch within safe operating area (SOA) and avoids latch-up or permanent failure. |
| IoT Edge Node Power Bus Protection | Notebook/Tablet Main Power Rail Protection |
Use Scenario: Securing 22V auxiliary rails in battery-powered IoT gateways subjected to ESD during field servicing or cable insertion. IC Role / Device Role / Timing Role: Single-device solution replacing multi-stage TVS+MOV networks for space-constrained edge nodes. Use Value: Delivers ±30kV ESD immunity and 40A surge rating in 2.56 mm² footprint - reduces BOM count and PCB area vs. discrete alternatives. |
Use Scenario: Protecting main system power input (e.g., barrel jack or USB-C port) in thin-client notebooks where thermal headroom is limited. IC Role / Device Role / Timing Role: Low-capacitance (175pF), low-leakage (≤600nA) suppressor minimizing standby power loss and board heating. Use Value: Stable 27.5–28V clamping at 125°C ambient - ensures protection integrity during sustained high-temperature operation without derating. |
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-6 package, identical marking code "T22" - direct Semtech factory variant with same performance and qualification. | No functional difference; used interchangeably in USB-C and industrial designs per Semtech documentation. | Select TDS2211P.C when sourcing directly from Semtech distribution channels with full traceability. |
| SP1003-02HTG | Lower 12V working voltage, 20A IPP, 22V clamping - not suitable for 22V systems; different SOD-323 package limits PCB layout flexibility. | Targeted for 5–12V data lines (e.g., USB 2.0, UART), not 22V power rails; lacks IEC 61000-4-5 surge rating. | Not recommended for SMDA15CN-5.TBT replacement; only consider for lower-voltage signal-line protection. |
Compared with SMDA15CN-5.TBT, TDS2211P.C offers identical protection performance and drop-in compatibility, while SP1003-02HTG serves fundamentally different voltage-class applications and cannot substitute in 22V bus protection without redesign.

FAQ
What is the maximum continuous operating voltage for SMDA15CN-5.TBT?
The SMDA15CN-5.TBT has a reverse stand-off voltage (VRWM) of 22V, meaning it can continuously withstand up to 22V DC on the protected line without triggering. This makes it suitable for USB PD 20V nominal systems with safety margin, and aligns with its specified 25–27.9V breakdown voltage (VBR) at 1mA test current.
Does SMDA15CN-5.TBT meet IEC 61000-4-5 surge immunity standards?
Yes, SMDA15CN-5.TBT is rated for 40A peak pulse current (tp = 8/20μs) and ±1kV (1.2/50μs, RS = 42Ω) per IEC 61000-4-5, satisfying Level 4 industrial surge immunity requirements. Its 27.5–28V clamping voltage ensures downstream components remain within safe operating limits during standardized surge events.
How does SMDA15CN-5.TBT differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN), SMDA15CN-5.TBT uses a triggered FET shunt that maintains ~27.5–28V clamping from 24A to 40A. Its dynamic resistance drops to 20mΩ under surge, delivering flat, temperature-stable clamping - critical for protecting sensitive 22V-rated ICs.
What is the recommended PCB layout for optimal performance of SMDA15CN-5.TBT?
Place SMDA15CN-5.TBT as close as possible to the protected connector. Connect all three GND pins (1, 2, 3) to a solid ground plane using ≥3 vias each, and tie all three IN pins (4, 5, 6) together with a short, wide trace. Avoid thermal pads - energy is dissipated in the FET channel, not the die junction.
Is SMDA15CN-5.TBT compatible with automated SMT assembly processes?
Yes, SMDA15CN-5.TBT is supplied in tape-and-reel format (3,000 pcs/reel) and features a standard DFN-6 footprint compatible with industry-standard reflow profiles. Its Pb-free, RoHS-compliant lead finish and UL 94V-0 molding compound meet IPC-J-STD-020 moisture sensitivity level (MSL) 1 requirements for unlimited floor life.
