Product details
Overview
TESD5V0V4UCU6 from Taiwan Semiconductor is a 5V-rated, 3pF ESD protection array in SOT-363 package, featuring ±15kV air/±8kV contact ESD immunity, 6A peak pulse current, and 25V clamping voltage at 6A - deployed for high-speed data line protection in DVI and Ethernet interfaces.
For engineers reviewing the TESD5V0V4UCU6 datasheet, TESD5V0V4UCU6 pinout, TESD5V0V4UCU6 application, or TESD5V0V4UCU6 equivalent, key selection criteria include working voltage (5V), junction capacitance (3pF I/O-to-GND), clamping performance (25V @ 6A), RoHS/halogen-free compliance, and SOT-363 footprint compatibility with space-constrained digital interface layouts.
Technical Context
This monolithic ESD protection device integrates four bidirectional TVS diodes in a single die within a 6-pin SOT-363 package, configured to protect four independent I/O lines against transient overvoltage events. It operates with a 5V working standoff voltage and delivers sub-25V clamping under 6A 8/20μs surge conditions.
The device meets IEC 61000-4-2 Level 4 ESD immunity and exhibits low 3pF capacitance between any I/O pin and GND - critical for preserving signal integrity on high-speed digital buses such as DVI and Gigabit Ethernet without introducing timing skew or attenuation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5 V - Maximum continuous operating voltage before conduction; ensures no leakage or interference during normal 5V logic operation. |
| CJ (I/O to GND) | 3 pF - Low capacitance preserves signal rise/fall times on high-speed interfaces like DVI and 1000BASE-T Ethernet. |
| VC @ IPP = 6A | 25 V - Clamping voltage limits downstream IC stress during 8/20μs surges, protecting 3.3V/5V interface receivers. |
| IPP | 6 A - Peak surge current handling capability per channel, aligned with IEC 61000-4-5 surge test requirements. |
| ESD Rating | ±15 kV (air), ±8 kV (contact) - Full compliance with IEC 61000-4-2 Level 4, enabling robust system-level ESD certification. |
| V(BR) @ IR = 1mA | 6 V - Breakdown threshold ensures reliable turn-on only during transients, minimizing standby power loss and false triggering. |
Pinout & Package
SOT-363 (SC-70-6) surface-mount package with 6 terminals, matte tin-plated leads, moisture sensitivity level 1, and UL 94 V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I/O Channel 1 Anode | Bidirectional ESD path for first protected line; connects internally to common cathode structure. |
| 2 | GND | Common reference node for all four channels; must be low-inductance connection to system ground plane. |
| 3 | I/O Channel 1 Cathode | Completes bidirectional clamp path for Channel 1; tied internally to Pin 2 via TVS junction. |
| 4 | I/O Channel 2 Anode | Second independent ESD protection path; electrically isolated from other I/O pins except through shared GND. |
| 5 | I/O Channel 2 Cathode | Paired with Pin 4 to form second bidirectional TVS; identical clamping behavior to Pin 1/3 pair. |
| 6 | NC / Not Connected | No internal connection; left unconnected per datasheet - not used for signal or biasing. |

IC Role / Device Role: Per-lane ESD clamp on transformer-coupled or direct-coupled Ethernet physical layer signals. Use Value: Enables full IEC 61000-4-2 Level 4 compliance without degrading 1000BASE-T signal quality or requiring larger-footprint alternatives. |
| Projection TV Monitors | Flat Panel Displays |
Use Scenario: Shielding LVDS or RSDS video interface lines between mainboard and projection engine control boards from user-accessible port ESD. IC Role / Device Role: Point-of-entry protection on high-speed video data lanes carrying clock and pixel data. Use Value: Delivers 25V clamping at 6A while adding only 3pF per I/O-to-GND path - preventing jitter accumulation and pixel corruption. | Use Scenario: Protecting embedded DisplayPort or eDP lanes in LCD/LED monitor assemblies where space constraints limit discrete TVS options. IC Role / Device Role: Compact 4-channel ESD array covering panel interface, touch controller, and backlight control lines. Use Value: Integrates four protection paths in one SOT-363 footprint, reducing PCB area by >60% versus discrete 0402 TVS diodes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5V3U4U-2/TR | Higher VWM (5.3V), slightly higher CJ (4.5pF I/O-to-GND), same SOT-363 package and 6A IPP. | Marginally less suitable for strict 5V rail systems due to elevated standoff; may affect leakage in low-power standby modes. | Select when system tolerates 5.3V VWM and requires alternate supply-chain availability. |
| TPD4E001DRYR | Lower CJ (0.7pF I/O-to-GND), same 5V VWM, but lower IPP (4A) and different pinout (no NC pin). | Better for >3GHz RF-adjacent digital lines; unsuitable where 6A surge margin is required per IEC 61000-4-5. | Prefer for ultra-high-speed interfaces where capacitance dominates design priority over peak current rating. |
Compared with ESD5V3U4U-2/TR and TPD4E001DRYR, the TESD5V0V4UCU6 offers optimal balance of 5V precision standoff, 3pF capacitance, and 6A surge capability in a standard SOT-363 layout - making it especially suited for cost-sensitive, high-volume DVI and Ethernet endpoint designs requiring proven Level 4 ESD robustness.

FAQ
What is the clamping voltage of TESD5V0V4UCU6 at 6A surge current?
The TESD5V0V4UCU6 exhibits a maximum clamping voltage of 25 V when subjected to a 6 A, 8/20 μs impulse current waveform. This value is measured between any I/O pin and GND under standardized test conditions and ensures downstream 3.3V/5V interface ICs remain within safe operating limits during surge events. The TESD5V0V4UCU6 maintains this performance across its full operating temperature range.
Does TESD5V0V4UCU6 support IEC 61000-4-2 Level 4 ESD immunity?
Yes, the TESD5V0V4UCU6 fully complies with IEC 61000-4-2 Level 4, delivering ±15 kV air discharge and ±8 kV contact discharge protection. This rating is verified per the standard's test methodology and enables system-level ESD certification without supplemental protection components. The TESD5V0V4UCU6 achieves this while maintaining only 3 pF capacitance to GND.
What is the junction capacitance specification for TESD5V0V4UCU6?
The TESD5V0V4UCU6 has a typical junction capacitance of 3 pF measured between any I/O pin and GND at 1 MHz and 0 V reverse bias. This low value is critical for preserving signal integrity on high-speed digital interfaces such as DVI and 1000BASE-T Ethernet. The device also specifies 1.5 pF between I/O pins, further minimizing crosstalk.
What package type does TESD5V0V4UCU6 use, and what are its key mechanical attributes?
The TESD5V0V4UCU6 uses the SOT-363 (SC-70-6) surface-mount package with matte tin-plated leads, UL 94 V-0 flammability rating, and moisture sensitivity level 1 per J-STD-020. Its marking code is F54, and it weighs approximately 6.99 mg. The package supports reflow soldering per J-STD-002 and passes JESD 201 Class 1A whisker testing.
Is TESD5V0V4UCU6 RoHS and halogen-free compliant?
Yes, the TESD5V0V4UCU6 is RoHS compliant and halogen-free in accordance with IEC 61249-2-21. These compliance statements are confirmed in the official Taiwan Semiconductor datasheet revision D2109 and apply to all units shipped under the TESD5V0V4UCU6 RFG ordering code. No lead, cadmium, mercury, hexavalent chromium, PBB, or PBDE substances exceed EU RoHS thresholds.
