Product details
Overview
TVS2201DRBR from Texas Instruments is a bidirectional flat-clamp surge protection device designed for industrial signal line protection. It delivers ±22 V standoff voltage, 29.6 V clamping voltage at 30 A (8/20 µs), 62 pF capacitance, and survives 5,000+ repetitive 30-A surges at 125°C - enabling robust protection in PLC I/O, analog inputs, and USB Type-C VBUS lines.
For engineers reviewing the TVS2201DRBR datasheet, TVS2201DRBR pinout, TVS2201DRBR application, or TVS2201DRBR equivalent, key selection criteria include bidirectional ±22 V operation, flat-clamp precision under high-temperature surge stress, low leakage (<2 nA @ 27°C), minimal capacitive loading, and SON-8 package compatibility with space-constrained industrial layouts.
Technical Context
The TVS2201DRBR implements an active feedback-controlled dual-FET clamp architecture-not a passive Zener or avalanche diode-enabling tight voltage regulation during transients. Its dynamic resistance is 40 mΩ, ensuring <1 V voltage rise under 25-A surge current, and it maintains full surge capability up to 125°C with zero derating.
It integrates Level 4 IEC 61000-4-2 ESD (±8 kV contact / ±15 kV air), 80-A IEC 61000-4-4 EFT, and meets IEC 61000-4-5 (30 A, 8/20 µs) and IEC 61643-321 (4 A, 10/1000 µs) standards - all within a single 3.0 mm × 3.0 mm SON-8 package with floating thermal pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage | ±22 V - enables bipolar signal protection and reverse-wiring tolerance without breakdown |
| Clamp Voltage | 29.6 V at 30 A (8/20 µs) - limits downstream IC exposure below absolute maximum ratings of common analog/USB controllers |
| Surge Current Rating | ±30 A (IEC 61000-4-5, 8/20 µs) - satisfies industrial 1-kV/42-Ω open-circuit surge requirement |
| Capacitance | 62 pF - minimizes signal distortion on high-speed analog or USB Type-C VBUS lines |
| Leakage Current | 2 nA typical @ 27°C - reduces power loss and measurement error in precision sensor front-ends |
| Operating Temp | –40°C to +125°C - supports continuous operation in harsh industrial environments without performance shift |
| Dynamic Resistance | 40 mΩ - ensures stable clamping voltage across surge amplitude variation (e.g., +1 V rise at 25 A) |
Pinout & Package
TVS2201DRBR uses an 8-pin SON (DRB) package with 3.0 mm × 3.0 mm body size and a floating exposed thermal pad. The package is RoHS-compliant, moisture-sensitivity level 2 (260°C peak reflow), and supplied in 3,000-unit tape-and-reel format.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | IN | Surge-protected channel input - bidirectionally clamps both positive and negative transients |
| 5, 6, 7, 8 | GND | Ground return path for surge current - must connect to low-impedance system ground plane |
| Exposed Pad | FLOAT | Thermal pad must remain unconnected - grounding degrades negative-voltage tolerance and causes failure under reverse wiring |
Key Features
| Feature | Design Value |
|---|---|
| Flat-Clamp Regulation | Active feedback loop maintains <±0.5 V clamping variation across 10–30 A surge range - enables use of lower-voltage-tolerance downstream ICs |
| Zero-Temperature Derating | Full 30-A surge rating preserved at 125°C - eliminates design margin loss seen in traditional TVS diodes |
| Bidirectional Symmetry | ±22 V VRWM and matched positive/negative clamping - protects against miswiring and bipolar analog signals without polarity constraints |
| Integrated ESD/EFT | Level 4 IEC 61000-4-2 (±8 kV contact) + 80-A IEC 61000-4-4 - reduces need for supplemental protection components |
| High-Reliability Cycling | Validated for >5,000 repetitive 30-A surges at 125°C with no parameter shift - ensures long-term field robustness in critical infrastructure |
Applications
| Industrial Sensor I/O | PLC Analog Input Modules |
|---|---|
Use Scenario: Protecting 4–20 mA or 0–10 V sensor signal lines from lightning-induced surges in factory-floor environments. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed at connector entry point to shunt fault energy before reaching ADC or isolation amplifier. Use Value: ±22 V standoff matches common industrial signal ranges; 62 pF capacitance avoids filtering effects on slow analog signals. | Use Scenario: Safeguarding programmable logic controller (PLC) analog input channels against coupling from adjacent motor drives or relay switching. IC Role / Device Role / Timing Role: Flat-clamp protector on each channel's input trace, minimizing voltage overshoot during fast-rising transients. Use Value: 40 mΩ dynamic resistance limits clamping voltage rise to <1 V even at 25-A surge - preserving signal integrity and ADC accuracy. |
| USB Type-C VBUS Protection | Medical Equipment Signal Interfaces |
Use Scenario: Clamping VBUS line against hot-swap ringing, mechanical shorts, or connector faults that apply –20 V or +30 V spikes. IC Role / Device Role / Timing Role: Primary overvoltage clamp between USB-C receptacle and port controller (e.g., TPS65982), placed <2 mm from connector. Use Value: Bidirectional ±22 V operation blocks reverse shorts without triggering; 29.6 V clamp stays safely below 32-V absolute max of common USB PD controllers. | Use Scenario: Shielding patient-connected analog biosignal paths (ECG, EEG) from ESD and EFT events per IEC 60601-1-2. IC Role / Device Role / Timing Role: Low-leakage transient suppressor on isolated front-end amplifier inputs, minimizing DC offset drift and noise injection. Use Value: 2 nA leakage @ 27°C prevents input bias current errors; 62 pF capacitance avoids resonance with high-impedance electrode interfaces. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TVS2200DRBR | Unidirectional; 27.7 V clamp at 40 A; ±22 V standoff only in forward direction | Not suitable for reverse-wiring or bipolar signaling; requires external series diode for negative protection | Select only when signal polarity is strictly positive and reverse fault conditions are excluded by system design |
| TVS1401DRBR | Bidirectional; 20.5 V clamp at 30 A; ±14 V standoff | Lowers clamping voltage but reduces operating range - unsuitable for ±22 V systems or 24 V industrial rails | Choose for 12 V nominal systems where tighter clamping is prioritized over rail coverage |
Compared with TVS2201DRBR, TVS2200DRBR lacks reverse-polarity protection and cannot withstand miswiring, while TVS1401DRBR sacrifices standoff headroom needed for 24 V industrial buses - making TVS2201DRBR the only option validated for ±22 V bidirectional robustness with flat-clamp precision.

FAQ
What is the maximum surge current rating for TVS2201DRBR?
The TVS2201DRBR is rated for ±30 A under IEC 61000-4-5 (8/20 µs) waveform at ambient temperatures up to 125°C, with no derating applied. This rating was verified across 5,000 repetitive strikes at 125°C, confirming sustained performance in demanding industrial environments. The TVS2201DRBR achieves this via active flat-clamp regulation, not passive avalanche breakdown.
Does TVS2201DRBR require a power supply or bias voltage to operate?
No, the TVS2201DRBR is a passive clamping device with no external power or bias required. It operates solely on the voltage present at its IN pins relative to GND. Its internal feedback circuitry draws no quiescent current - only conducting during overvoltage events. The TVS2201DRBR remains fully functional across its entire ±22 V standoff range without auxiliary supplies.
Can TVS2201DRBR be used for reverse-voltage protection in addition to surge suppression?
Yes - the TVS2201DRBR's symmetrical ±22 V standoff enables robust reverse-wiring tolerance. When –20 V is applied to the IN pin (e.g., due to connector short), the device remains in high-impedance state without conduction or degradation. Unlike unidirectional TVS devices such as TVS2200DRBR, the TVS2201DRBR does not fail under reverse polarity, making it ideal for field-deployed equipment prone to installation errors.
What is the significance of the floating thermal pad on TVS2201DRBR?
The exposed thermal pad on TVS2201DRBR must remain electrically floating - not connected to GND or any other net. Grounding the pad compromises the device's negative-voltage tolerance and can cause catastrophic failure during reverse-wiring events. The floating configuration preserves full ±22 V operational symmetry and ensures reliable flat-clamp behavior across temperature and polarity extremes.
How does TVS2201DRBR differ from standard TVS diodes in surge response?
The TVS2201DRBR uses an active FET-based feedback loop to achieve flat-clamp regulation, resulting in <±0.5 V clamping variation across 10–30 A surge currents. Standard TVS diodes exhibit rising clamping voltage with increasing current (due to dynamic impedance), often exceeding 40 V at 30 A. This precision allows system designers to select downstream ICs with lower voltage tolerances - reducing cost and complexity without sacrificing protection.
