Product details
Overview
PESD5V0F2UT from Nexperia is a dual-channel unidirectional ESD protection diode in SOT23 package, designed to safeguard two high-speed data lines against IEC 61000-4-2 ±8 kV and ISO 10605 ±8 kV ESD events. It delivers 0.47 pF typical capacitance, 5 V reverse standoff voltage, and 3.3 V clamping voltage at 8 A TLP, enabling reliable protection for USB2.0 and HDMI interfaces without signal integrity degradation.
For engineers reviewing the PESD5V0F2UT datasheet, PESD5V0F2UT pinout, PESD5V0F2UT application, or PESD5V0F2UT equivalent, key selection criteria include ultra-low capacitance for >480 Mbps data rates, common-anode dual-diode topology for compact two-line protection, and 175 °C junction temperature rating for automotive under-hood or industrial edge deployments.
Technical Context
This device implements a snap-back clamping structure with negative dynamic resistance, reducing clamping voltage during ESD transients while maintaining low leakage (<50 nA at 5 V). Its bidirectional protection capability arises from two independent cathodes (pins 1 and 2) tied to a shared anode (pin 3), enabling separate line-to-ground suppression paths.
Designed specifically for high-speed serial buses, it meets stringent impedance and coupling constraints: capacitance matching (ΔCd/Cd ≤1%) ensures balanced signal integrity across both protected lines, and dynamic resistance of 0.3 Ω enables rapid energy shunting without thermal runaway under 8/20 µs surge conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Ensures no conduction during normal 3.3 V/5 V bus operation; defines maximum continuous working voltage. |
| Clamping Voltage | 3.3 V at 8 A TLP - Limits transient overvoltage seen by downstream PHY to safe levels below IC absolute maximum ratings. |
| Diode Capacitance | 0.47 pF - Enables minimal signal distortion on USB2.0 (480 Mbps) and HDMI 1.4 (up to 3.4 Gbps) channels. |
| ESD Rating | ±8 kV IEC 61000-4-2 contact - Meets international immunity requirements for consumer and industrial end-equipment. |
| Junction Temperature | 175 °C - Supports operation in high-ambient environments such as automotive infotainment head units or industrial gateways. |
| Peak Pulse Current | 4 A (8/20 µs) - Handles repetitive surges per IEC 61000-4-5 Level 3 without degradation. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Connects to first protected data line (e.g., USB D+); conducts ESD current to common anode during positive transients. |
| 2 | K2 (Cathode 2) | Connects to second protected data line (e.g., USB D−); provides independent clamping path with matched capacitance. |
| 3 | CA (Common Anode) | Connected to system ground; serves as shared return path for both diodes, minimizing PCB layout area and inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance matching | ΔCd/Cd ≤1% - Ensures identical signal delay and reflection characteristics across both protected differential pairs. |
| Snap-back clamping architecture | Dynamic resistance = 0.3 Ω - Reduces clamping voltage by >40% vs. standard TVS, limiting stress on connected PHY ICs. |
| High-temperature reliability | Tj = 175 °C - Validated for uninterrupted operation in sealed enclosures with limited airflow, e.g., automotive telematics modules. |
| IEC/ISO dual-standard compliance | ±8 kV per both IEC 61000-4-2 and ISO 10605 - Eliminates need for separate qualification testing in global OEM programs. |
Applications
| USB2.0 Interface Protection | HDMI 1.4 Data Lane Protection |
|---|---|
Use Scenario: Protecting full-speed USB2.0 D+/D− differential pair in portable docking stations exposed to frequent human-hand ESD events. IC Role / Device Role / Timing Role: Unidirectional line-to-ground ESD clamp placed immediately before USB transceiver PHY input pins. Use Value: 0.47 pF capacitance avoids signal rise-time degradation beyond USB2.0 specification limit (1–2 ns), preserving eye diagram margin. |
Use Scenario: Shielding TMDS clock and data channels in HDMI source devices (e.g., set-top boxes) against contact discharge during cable insertion. IC Role / Device Role / Timing Role: Dual-channel transient suppressor mounted at HDMI connector footprint, with CA grounded via shortest possible trace. Use Value: Matched capacitance (≤1% mismatch) prevents skew-induced jitter accumulation across differential lanes operating at 3.4 Gbps. |
| DisplayPort 1.2 Auxiliary Channel | eSATA Gen II Host Port |
Use Scenario: Securing DP AUX CH+/− lines in thin-client displays where space-constrained layout limits discrete protection options. IC Role / Device Role / Timing Role: Common-anode dual-diode providing simultaneous protection for bidirectional 1 Mbps I²C-like auxiliary channel. Use Value: 5 V VRWM aligns with DP AUX supply rail, preventing false triggering during hot-plug detection sequences. |
Use Scenario: Hardening eSATA host controller ports in NAS enclosures subjected to repeated cable mating cycles in dusty environments. IC Role / Device Role / Timing Role: High-reliability ESD guard for 3 Gbps serial link, placed adjacent to SATA connector with controlled impedance routing. Use Value: 4 A 8/20 µs surge rating exceeds IEC 61000-4-5 Level 3 requirement, ensuring long-term robustness across >10,000 insertions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor ESDE0524P | 0.5 pF capacitance; 5.5 V VRWM; ±15 kV IEC 61000-4-2 air discharge | Higher ESD rating suits medical handhelds; slightly higher capacitance may impact >5 Gbps links | Select when air-discharge immunity >12 kV is mandatory and USB3.0+ is not used. |
| Vishay VEML3010 | 0.35 pF capacitance; 3.3 V VRWM; ±8 kV IEC 61000-4-2; SOD-323 package | Lower standoff voltage restricts use to 3.3 V-only systems; smaller package increases assembly complexity | Choose only for space-constrained 3.3 V embedded designs where <0.4 pF is critical. |
Compared with ESDE0524P and VEML3010, PESD5V0F2UT offers optimal balance of 5 V compatibility, 0.47 pF capacitance, and SOT23 manufacturability-making it the preferred choice for cost-sensitive, high-volume USB2.0/HDMI 1.4 designs requiring proven field reliability.

FAQ
What is the maximum recommended trace length between PESD5V0F2UT and the protected data line?
Trace length from each cathode (pins 1 or 2) to its respective data line must be ≤2 mm, and from common anode (pin 3) to ground plane ≤3 mm. Longer traces increase inductance, degrading clamping response time and raising peak let-through voltage during 1 ns ESD rise-time events.
Can PESD5V0F2UT protect bidirectional data lines like I²C without additional components?
No-PESD5V0F2UT is unidirectional and only protects against positive transients on K1/K2 relative to CA. For true bidirectional protection (e.g., I²C SDA/SCL), a dual-channel bidirectional device such as PESD2CAN is required; this part clamps only when voltage exceeds +5 V on either line.
Does the 0.47 pF capacitance value apply to both diode channels independently?
Yes-capacitance is measured from pin 1 to pin 3 and pin 2 to pin 3 separately; typical values are identical (0.47 pF), and matching tolerance is specified as ΔCd/Cd ≤1%, ensuring symmetrical loading on differential pairs like USB D+/D−.
Is PESD5V0F2UT qualified for automotive AEC-Q200 stress testing?
No-this device is not AEC-Q200 qualified. While its 175 °C junction rating supports under-hood ambient temperatures, Nexperia does not list it in their automotive-grade product catalog, and no AEC-Q200 test reports are published for PESD5V0F2UT.
