Product details
Overview
TS13101-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 24–40A, 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 TS13101-QFNR datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, validated DFN-6 pin mapping, real-world clamping stability data across temperature and current, and direct alternatives for 22V EOS protection design-in.
Technical Context
The TS13101-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 6-pin DFN package integrates three parallel input terminals (pins 4–6) and three ground terminals (pins 1–3), requiring all six pins to be connected for full 40A surge rating and minimal parasitic inductance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches USB PD 20V nominal bus with 2V margin for transients |
| Clamping Voltage | 27.5–28V at 24–40A - stays below 30V damage threshold of most 30V-rated load switches and PD controllers |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD requirements |
| Dynamic Resistance | 20mΩ - enables flat clamping curve and low voltage overshoot during fast-rising surges |
| Junction Capacitance | 175pF at 22V/1MHz - suitable for DC power rails and low-speed control lines, not high-speed data |
Pinout & Package
TS13101-QFNR is housed in a RoHS-compliant, halogen-free 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 soldered for rated performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Low-inductance ground return path; all three must connect to solid ground plane via multiple vias for 40A surge conduction |
| Pins 4, 5, 6 | IN | Parallel-connected input terminals for protected line (e.g., VBus); all three required to distribute surge current and minimize trace inductance |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies <0.5V from 24A to 40A - eliminates need for overrating IPP to meet voltage limits |
| Temperature-stable protection | Clamping holds at ~27.6V from −40°C to +125°C - removes derating uncertainty in hot industrial environments |
| Low dynamic resistance | 20mΩ enables sub-1V overshoot during 100A/μs dV/dt events - critical for protecting sensitive gate drivers |
| High-energy surge handling | 1120W peak pulse power (8/20μs) - sustains repeated lightning-induced surges without degradation |
| DFN-6 space efficiency | 1.6mm × 1.6mm footprint saves >60% board area vs. SO-8 TVS solutions - enables compact USB-C port designs |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20V USB PD VBus lines against ESD, lightning-induced surges, and connector hot-plug transients in notebooks and docking stations. IC Role / Device Role / Timing Role: Transient diverting suppressor placed at connector entry point, shunting surge current to ground before it reaches PD controller or buck converter. Use Value: Maintains 27.6V clamping at 40A and 125°C - prevents overvoltage damage to 30V-rated PD ICs where standard TVS would clamp >38V at same conditions. |
Use Scenario: Safeguarding enable and input pins of high-side load switches (e.g., HS2950P) in remote meters, robotics, and IoT edge nodes exposed to field surges. IC Role / Device Role / Timing Role: Primary front-end EOS protector on VIN rail, limiting voltage seen by internal FET gate oxide and overvoltage protection circuitry. Use Value: 20mΩ dynamic resistance ensures <1V overshoot during 8/20μs surges - keeps stress on load switch within safe SOA, extending reliability in ungrounded deployments. |
| 22V Industrial Control Power Rails | USB-C Docking Station VBus Protection |
Use Scenario: Securing 24V DC input rails in programmable logic controllers (PLCs) and HMI panels subject to inductive switching transients and EFT bursts. IC Role / Device Role / Timing Role: Standalone EOS suppressor on main power entry, operating in parallel with bulk capacitance and upstream fusing. Use Value: ±4kV EFT immunity (IEC 61000-4-4) and stable 27.6V clamping ensure uninterrupted operation during 5kHz burst noise - avoids system resets or latch-up. |
Use Scenario: Protecting dual-role VBus paths in multi-port USB-C docks handling up to 100W PD negotiation and simultaneous charging/data transfer. IC Role / Device Role / Timing Role: Per-port TDS device per VBus line, coordinated with low-capacitance RClamp3371ZC on SuperSpeed lanes. Use Value: 175pF capacitance avoids signal integrity impact on 5V/9V/15V/20V PD negotiation lines - unlike higher-capacitance TVS arrays that distort CC logic timing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Same die, identical electrical specs and DFN-6 package - direct form-fit-function replacement with identical marking (T22) | No functional difference; used interchangeably in Semtech reference designs for USB-C and load switch protection | Select TS13101-QFNR for QFN-style branding consistency in new BOMs; TDS2211P remains valid for legacy procurement |
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.5V VC @ 12.3A; higher clamping, no temperature stability, 500W PPPK | Requires 3× parallel devices to reach 40A; clamping rises to >42V at 125°C - insufficient for tight-margin PD controllers | Only suitable where clamping voltage margin >15V exists and ambient temperature stays <60°C |
Compared with TDS2211P, TS13101-QFNR offers identical protection performance with updated part numbering for distribution channel alignment; compared with SMAJ22A, it delivers 11V lower clamping at full surge rating and eliminates thermal derating - enabling smaller, more robust 22V rail protection without redesign.

FAQ
What is the exact clamping voltage specification for TS13101-QFNR at 40A surge current?
The TS13101-QFNR clamps at 27.6–28V under 40A peak pulse current (tp = 1.2/50μs voltage + 8/20μs current combination waveform, RS = 2Ω), as guaranteed by design and validated across −40°C to +125°C. This value is confirmed in the Electrical Characteristics table of the official Semtech datasheet Rev 2.5.
Does TS13101-QFNR require a thermal pad on the PCB bottom side?
No, TS13101-QFNR does not require an external thermal pad. The device dissipates surge energy in the silicon die, not through conduction to the PCB. The DFN package has no exposed thermal slug; layout guidance emphasizes low-inductance grounding via multiple vias to pins 1–3 instead of thermal relief.
Can TS13101-QFNR be used on high-speed data lines like USB SuperSpeed or PCIe?
No, TS13101-QFNR is not suitable for high-speed data lines. Its 175pF junction capacitance at 22V would severely degrade signal integrity on >100MHz interfaces. It is intended exclusively for DC power rails and low-speed control lines such as USB-C VBus, load switch EN/VIN, or industrial 22V control inputs.
How does TS13101-QFNR differ from standard TVS diodes in surge response behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN), TS13101-QFNR uses a triggered FET architecture that maintains near-constant clamping (~27.6V) from 24A to 40A and across temperature. Its 20mΩ dynamic resistance ensures minimal voltage overshoot during fast dV/dt events, a key advantage over fixed-RDYN TVS devices.
Is TS13101-QFNR pin-compatible with TDS2211P?
Yes, TS13101-QFNR is pin-compatible with TDS2211P: both use identical 6-pin DFN (1.6mm × 1.6mm) packages with pins 1–3 as GND and pins 4–6 as IN. Layout, solder mask, and land pattern are interchangeable; no PCB changes are required when substituting TS13101-QFNR for TDS2211P in existing designs.
