Product details
Overview
TVS1400DRVR from Texas Instruments is a unidirectional flat-clamp transient voltage suppression (TVS) diode designed for robust surge protection on industrial 12 V signal and power lines. It delivers 43 A IEC 61000-4-5 (8/20 µs) surge current handling, 14 V reverse standoff voltage, 18.4 V typical clamping voltage at 43 A, 120 pF capacitance, and 2.2 nA leakage at 27°C - enabling precise protection of sensitive ADC inputs and PLC I/O circuits without signal distortion.
For engineers reviewing the TVS1400DRVR datasheet, TVS1400DRVR pinout, TVS1400DRVR application, or TVS1400DRVR equivalent, key selection criteria include flat-clamp voltage regulation under high-temperature surge stress, minimal derating up to 125°C, bidirectional configuration capability via dual placement, low dynamic resistance (30 mΩ), and compatibility with space-constrained 2 mm × 2 mm SON layouts near connectors.
Technical Context
The TVS1400DRVR employs TI's proprietary Flat-Clamp feedback architecture to maintain tight clamping voltage control (<0.5 V variation across 24–43 A surge currents), eliminating overshoot during fast-rising transients. Its unidirectional operation relies on controlled avalanche breakdown at 16.9 V (typical), with forward clamp voltage limited to 5 V at 43 A surge.
Unlike conventional TVS diodes, it exhibits negligible thermal derating: maximum surge current remains stable at 43 A from –40°C to 125°C, supported by low junction-to-board thermal resistance (40 °C/W) and validated 5,000-cycle reliability testing at 125°C with no parameter shift in VBR, VCLAMP, or ILEAK.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VRWM) | 14 V - defines maximum continuous operating voltage before conduction begins; matches 12 V system rails with 1.7× safety margin. |
| Clamp Voltage (VCLAMP) | 18.4 V at 43 A (8/20 µs) - ensures downstream ICs with ±20 V absolute max ratings (e.g., ADS8689) remain within safe operating limits. |
| Surge Current Rating | 43 A (IEC 61000-4-5, 8/20 µs) - withstands industrial lightning-induced surges coupled through 42 Ω impedance at ±2 kV open-circuit voltage. |
| Leakage Current | 2.2 nA at 27°C, 16 nA at 85°C - enables use in ultra-low-power sensor front-ends without measurable bias error. |
| Capacitance | 120 pF at 1 MHz, 14 V bias - preserves signal integrity in analog sensor paths and high-speed digital I/O, avoiding >3 dB THD attenuation seen with SMBJ-class devices. |
| Dynamic Resistance | 30 mΩ - limits voltage rise during surge to ≤1.3 V above VBR, enabling predictable clamping behavior independent of current magnitude. |
| ESD Protection | ±21 kV contact / ±30 kV air-gap (IEC 61000-4-2 Level 4) - eliminates need for discrete ESD diodes in industrial I/O designs. |
Pinout & Package
TVS1400DRVR is housed in a thermally enhanced 6-pin WSON (DRV) package measuring 2.00 mm × 2.00 mm with an exposed thermal pad. The compact footprint reduces PCB area by 70% versus SMA/SMB packages while optimizing thermal dissipation via low RθJB (40 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pins 4, 5, 6) | Protected signal input | Common-anode connection for unidirectional clamping; accepts transient energy from upstream line and shunts to GND. |
| GND (Pins 1, 2, 3 + exposed pad) | Ground reference and thermal path | Low-inductance return path for surge current; exposed pad must be soldered to PCB ground plane for optimal thermal performance and EMI suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Flat-Clamp voltage regulation | Maintains clamping voltage within ±0.4 V across 24–43 A surge range, enabling reliable selection of lower-voltage-tolerance downstream ICs. |
| High-temperature surge endurance | Validated for 5,000 repetitive 35 A surges at 125°C with zero parameter drift - ensures lifetime reliability in enclosed industrial enclosures. |
| Minimal thermal derating | No reduction in rated surge current from –40°C to 125°C, unlike traditional TVS diodes that lose ≥50% capacity above 85°C. |
| Integrated ESD/EFT protection | Combines IEC 61000-4-2 Level 4 (±21 kV contact) and IEC 61000-4-4 (80 A EFT) in single device - reduces BOM count and layout complexity. |
| Low-slew-rate sensitivity | Clamps only when input dV/dt exceeds 2.5 V/µs (27°C) or 0.7 V/µs (125°C), preventing false triggering on normal signal edges. |
Applications
| Industrial Sensor I/O | Solid State Drives |
|---|---|
Use Scenario: Protecting 4–20 mA current-loop transmitters and RTD/thermocouple analog inputs against lightning-induced surges in factory automation cabinets.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ14A | DO-214AA package (4.5 mm × 3.9 mm); 1500 pF capacitance; 27.7 V clamping at 33.2 A; 100× higher leakage (200 nA @ 25°C). | Used in legacy industrial designs with larger board area; unsuitable for high-speed analog or dense PCB layouts due to parasitic capacitance. | Select SMBJ14A only if board space permits and signal bandwidth <1 MHz; TVS1400DRVR preferred for new designs requiring low capacitance and thermal stability. |
| TPD4E05U06DQAR | Quad-channel ESD array in USON-10; 5.5 V standoff; 12 V clamping; 0.5 pF per channel; rated for 4 A (8/20 µs), not 43 A surge. | Targeted at USB/HDMI/low-power data lines; lacks IEC 61000-4-5 surge rating and cannot replace TVS1400DRVR in power/signal line protection. | Use TPD4E05U06DQAR for secondary ESD protection on high-speed interfaces; TVS1400DRVR remains mandatory for primary surge defense on 12 V rails and sensor I/O. |
Compared with SMBJ14A and TPD4E05U06DQAR, TVS1400DRVR uniquely combines 43 A surge capability, 120 pF capacitance, and flat-clamp regulation in a 2 mm × 2 mm package - making it the only viable option for next-generation industrial systems demanding simultaneous high-energy robustness and signal fidelity.

FAQ
What is the maximum ambient temperature at which TVS1400DRVR maintains full 43 A surge capability?
TVS1400DRVR maintains its full 43 A IEC 61000-4-5 (8/20 µs) surge rating across the entire specified ambient temperature range of –40°C to +125°C, with no thermal derating applied. This is confirmed by TI's 5,000-cycle reliability test at 125°C, where VBR, VCLAMP, and ILEAK showed zero measurable shift after stress - a key differentiator from conventional TVS diodes that lose ≥50% surge capacity above 85°C.
Can TVS1400DRVR be used in bidirectional configurations, and how does that affect its electrical parameters?
Yes, TVS1400DRVR can be configured bidirectionally by placing two units in series with opposite polarity, achieving ±14 V working voltage. While TI has not published full characterization data for this specific configuration, the TVS3300 bidirectional implementation shows <5% increase in breakdown and clamping voltages versus unidirectional mode - implying TVS1400DRVR would deliver ~±17.5 V clamping under symmetric 43 A surges. Layout must ensure matched trace lengths to avoid imbalance.
How does the 30 mΩ dynamic resistance of TVS1400DRVR impact system-level protection design?
The 30 mΩ dynamic resistance of TVS1400DRVR directly determines voltage overshoot during surge events: at 43 A, it contributes only 1.29 V (43 A × 0.03 Ω) above the 16.9 V breakdown voltage, yielding a total clamped voltage of ≤18.2 V. This allows designers to confidently select downstream components with 20 V absolute maximum ratings - such as the ADS8689 ADC - without margin erosion from resistive drop, simplifying voltage tolerance analysis and reducing overdesign.
What layout practices are critical to achieving optimal EMI suppression with TVS1400DRVR?
Optimal EMI suppression requires placing TVS1400DRVR within 2 mm of the protected connector, routing protected traces straight with rounded corners (≥1 mm radius), and connecting the exposed thermal pad directly to a solid internal ground plane using ≥4 thermal vias (0.3 mm diameter). These practices minimize loop inductance, reduce magnetic coupling to adjacent traces, and ensure surge current returns via the lowest-impedance path - critical for passing IEC 61000-4-2/4-5 emissions tests.
Is TVS1400DRVR compatible with lead-free reflow processes, and what is its moisture sensitivity level?
Yes, TVS1400DRVR is RoHS-compliant with NiPdAu lead finish and rated MSL Level-1 (260°C peak reflow, unlimited floor life), making it fully compatible with standard lead-free reflow profiles. The WSON (DRV) package supports JEDEC J-STD-020-compliant thermal cycling without popcorn cracking or delamination, verified across 3,000+ cycles - essential for high-reliability industrial manufacturing.
