Product details
Overview
TS13103-QFNR from Semtech is a Transient Diverting Suppressor (TDS) 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), 27.5–28V 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 TS13103-QFNR datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, real-world clamping stability across temperature and current, and direct alternatives for 22V bus protection design.
Technical Context
The TS13103-QFNR 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 and across –40°C to +125°C due to decreasing RDS(on) under surge.
It operates with reverse stand-off voltage of 22V, breakdown voltage of 25–27.9V, and junction capacitance of 175pF at 22V/1MHz. Its low 20mΩ dynamic resistance enables stable energy diversion without thermal runaway, making it suitable for high-reliability 22V bus protection where conventional TVS devices exhibit rising clamping with current or temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC operating voltage on protected line without leakage or conduction. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures downstream 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 surge immunity for industrial equipment and USB PD input stages. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - provides robust handling of human-body-model ESD events in field-deployed devices. |
| Dynamic Resistance | 20mΩ - enables minimal voltage rise under surge, delivering superior clamping consistency vs. TVS diodes. |
| Junction Capacitance | 175pF at 22V/1MHz - low enough for 22V power rail protection without signal integrity impact on adjacent traces. |
| Operating Temp | –40°C to +125°C - supports operation in automotive cabin, industrial control, and ruggedized IoT environments. |
Pinout & Package
TS13103-QFNR is housed in a RoHS-compliant DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no solder mask defined). All six terminals are surface-mount; pins 1–3 are internally connected GND, pins 4–6 are internally connected IN - requiring parallel routing for optimal surge current sharing and low-inductance grounding.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground connection - all three must be tied to low-impedance ground plane via multiple vias to sustain 40A surge current. |
| 4, 5, 6 | IN | Protected line input - all three pins connect in parallel to the 22V bus (e.g., USB PD VBus) for distributed current handling and reduced trace inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Constant Clamping Voltage | 27.5–28V across full 24–40A surge range and –40°C to +125°C - eliminates derating needed for TVS diodes whose clamping rises with temperature and current. |
| FET-Based Shunt Architecture | Surge-rated MOSFET triggered by precision circuit - achieves <0.1Ω effective RDS(on), enabling low-loss energy diversion without junction heating failure. |
| Low Dynamic Resistance | 20mΩ - minimizes IR drop during surge, ensuring predictable clamping independent of PCB layout parasitics. |
| High-Energy Surge Rating | 1120W peak pulse power (8/20μs) - supports repeated lightning-induced transients per IEC 61000-4-5 without degradation. |
| Ultra-Low Leakage | 130–600nA at 22V - prevents measurable power loss on always-on 22V rails in battery-powered or energy-sensitive systems. |

Use Value: Delivers ±30kV ESD immunity and 40A surge capacity in 1.6×1.6mm footprint-reducing board area by >50% vs. discrete TVS+MOV solutions. |
Use Scenario: Protecting 22V backup power lines in NVMe SSDs or enterprise storage controllers during hot-swap events and system-level EFT exposure. IC Role / Device Role / Timing Role: Low-capacitance (175pF), low-leakage (≤600nA) clamp ensuring no signal coupling or standby current penalty on critical backup rails. Use Value: Stable 27.5–28V clamping preserves data retention circuitry integrity during 1.2/50μs surge tests-meeting IEC 61000-4-5 compliance without additional filtering. |
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 functional specification, same DFN-6 package, identical marking code T22 - confirmed as direct replacement per Semtech documentation. | No change required; validated for USB PD, load switch, and industrial 22V rail use cases. | Select TS13103-QFNR when sourcing from Aetrix Electronics with full traceability and volume procurement support. |
| SMAJ22A | Standard unidirectional TVS diode; 22V standoff, 35.5V min clamping at 12.5A (8/20μs); higher dynamic resistance (~0.5Ω); clamping rises with temperature. | Suitable only for lower-energy transients (<12.5A) and ambient-temperature-limited designs; requires derating above 85°C. | Choose SMAJ22A only if cost sensitivity outweighs clamping stability, temperature range, and surge margin requirements. |
Compared with TDS2211P and SMAJ22A, TS13103-QFNR delivers identical protection performance and form factor as TDS2211P but with Aetrix's supply chain assurance, while SMAJ22A offers lower cost at the expense of 8V higher clamping, 3× lower surge rating, and strong temperature dependence-making it unsuitable for high-reliability 22V bus protection.

FAQ
What is the clamping voltage behavior of TS13103-QFNR across temperature and current?
The TS13103-QFNR maintains a tightly bounded clamping voltage of 27.5–28V across its full rated peak pulse current range (24A to 40A, 8/20μs) and full operating temperature range (–40°C to +125°C). This stability results from its FET-based shunt architecture, where RDS(on) decreases under surge-unlike TVS diodes whose clamping voltage rises linearly with both current and temperature. The TS13103-QFNR datasheet confirms this behavior in Figures 3 and 4.
Is TS13103-QFNR pin-compatible with TDS2211P?
Yes, TS13103-QFNR is functionally and physically identical to TDS2211P: same DFN-6 package (1.6mm × 1.6mm × 0.55mm), identical pin configuration (pins 1–3 = GND, pins 4–6 = IN), matching marking code (T22), and fully aligned electrical specifications-including 22V working voltage, 40A surge rating, and 27.5–28V clamping. TS13103-QFNR is a direct replacement with no PCB or firmware changes required.
What is the maximum continuous operating voltage for TS13103-QFNR?
The TS13103-QFNR has a reverse stand-off voltage (VRWM) of 22V, meaning it can continuously block up to 22V DC without significant leakage or conduction. This makes it suitable for protecting 20V USB PD VBus lines and other 22V-rated power rails. Exceeding 22V risks premature conduction and accelerated degradation-designers must ensure system operating voltage stays within this limit.
How should the ground connections be implemented for optimal surge performance with TS13103-QFNR?
For optimal surge performance, all three GND pins (1, 2, 3) of TS13103-QFNR must be connected in parallel to a low-impedance ground plane using multiple thermal vias (≥4 per pin recommended). This minimizes ground loop inductance and ensures the full 40A surge current is safely diverted. The datasheet emphasizes that omitting any GND pin reduces peak current capability and compromises clamping consistency-especially critical in industrial and USB PD applications.
Does TS13103-QFNR require external components like series resistors or RC filters?
No, TS13103-QFNR is a self-contained transient suppressor requiring no external components for basic operation. Its integrated trigger circuit and surge-rated FET enable immediate activation at breakdown voltage without timing networks or biasing. However, layout best practices-such as placing TS13103-QFNR within 5mm of the protected connector and using short, wide traces to GND-are essential to preserve its 40A surge capability and 27.5–28V clamping performance.
