Product details
Overview
TS12001-C000DFNR 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 stable 27.5–28V clamping across temperature and current range. It is deployed in USB Type-C PD bus protection to safeguard controllers against voltage overshoot.
For engineers reviewing the TS12001-C000DFNR datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under 40A surge, DFN-6 thermal and layout performance, 175pF junction capacitance at 22V, and compatibility with industrial and portable device surge standards (IEC 61000-4-5 ±1kV).
Technical Context
The TS12001-C000DFNR uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit when transient voltage exceeds breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly constant-27.5–28V-across 24A to 40A peak pulse current due to decreasing RDS(on) under surge conditions.
It operates over −40°C to +125°C, maintains <600nA reverse leakage at 22V, and exhibits only 20mΩ dynamic resistance (8/20μs). Its functional architecture separates input (pins 4–6) and ground (pins 1–3) terminals to minimize parasitic inductance and maximize surge current handling.
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 | 27.5–28V at 40A (8/20μs) - ensures protected ICs (e.g., USB PD controllers) remain below damage threshold during worst-case surge |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for 22V power rail use without signal integrity impact on adjacent traces |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD immunity benchmarks |
| Dynamic Resistance | 20mΩ (8/20μs) - enables flat clamping response and minimizes voltage rise under increasing surge current |
Pinout & Package
TS12001-C000DFNR is housed in a Pb-free, RoHS-compliant DFN package measuring 1.6mm × 1.6mm × 0.55mm with 6 leads and UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected to maximize current sharing and minimize inductance |
| Pins 4, 5, 6 | IN | Protected line input; connects directly to VBus or power/data line requiring 22V EOS protection |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V from 24A to 40A surge - eliminates design margin inflation needed with traditional TVS |
| Temperature-stable clamping | Maintains 27.5–28V clamping from −40°C to +125°C - removes thermal derating calculations for industrial deployments |
| Low dynamic resistance | 20mΩ enables efficient energy shunting with minimal IR drop - critical for protecting low-voltage-tolerance load switches |
| High-energy surge rating | 1120W peak pulse power (8/20μs) - supports repeated surge events without parametric shift or failure |
| Compact DFN footprint | 1.6mm × 1.6mm area saves >60% board space vs. comparable SO-8 or SOT-23 TVS solutions |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
|

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 manufacturer-recommended replacement for TS12001-C000DFNR | Identical use cases: USB-C PD, load switch input, industrial 22V rail protection | Select TDS2211P when sourcing from Semtech's standard distribution channels; identical performance and qualification status |
| uClamp2411ZA | 24V working voltage, lower 20A IPP rating, higher 33V clamping, SOD-323 package | Better suited for CC/SBU lines in USB-C; not rated for 40A surges or 22V bus-level protection | Choose uClamp2411ZA only for low-current signal-line protection - not a functional substitute for TS12001-C000DFNR's power-rail role |
Compared with TS12001-C000DFNR, TDS2211P offers identical protection performance and form factor, while uClamp2411ZA serves a different voltage/current class and cannot replace TS12001-C000DFNR in 22V, 40A surge-critical applications.

FAQ
What is the maximum continuous operating voltage for TS12001-C000DFNR?
The TS12001-C000DFNR has a reverse stand-off voltage (VRWM) of 22V, meaning it is rated for continuous operation up to 22V DC on the protected line. Exceeding this voltage risks increased leakage current and potential degradation. The device begins clamping above 25V (VBR min), making 22V the safe upper limit for steady-state bus voltage in designs using TS12001-C000DFNR.
Does TS12001-C000DFNR require external bias or control signals?
No, TS12001-C000DFNR is a fully passive, self-triggering device. It contains an integrated precision trigger circuit and surge-rated FET - no external voltage, enable pin, or configuration is needed. The TS12001-C000DFNR activates automatically when transient voltage exceeds its breakdown threshold, making it drop-in compatible with existing PCB layouts designed for single-component protection.
How does TS12001-C000DFNR differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with peak pulse current (VC = VBR + IPP × RDYN), TS12001-C000DFNR maintains near-constant clamping (27.5–28V) from 24A to 40A due to its FET-based architecture and decreasing RDS(on). This eliminates the need to overspecify IPP to meet voltage thresholds - a key advantage confirmed in TS12001-C000DFNR's datasheet curves.
Can TS12001-C000DFNR be used on high-speed data lines like USB SS or PCIe?
No, TS12001-C000DFNR is not suitable for high-speed data lines. Its 175pF junction capacitance at 22V is optimized for power rails and low-frequency I/O, not signal integrity-critical paths. For USB SuperSpeed or DP/DM lines, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF); TS12001-C000DFNR should be reserved for VBus, CC, or load-switch input protection only.
What is the recommended PCB layout for optimal surge performance with TS12001-C000DFNR?
For optimal surge performance, place TS12001-C000DFNR as close as possible to the protected connector. Connect all three IN pins (4–6) via a single short, wide trace to the protected line, and tie all three GND pins (1–3) directly to a solid ground plane using multiple vias. Avoid thermal pads or isolated copper - energy is dissipated internally, and minimizing trace inductance is essential for achieving rated 40A performance.
