Product details
Overview
PESD3V3U1BCSF from Nexperia is a bidirectional ESD protection diode in a DSN0603-2 (SOD962-2) package, designed to protect one signal line against IEC 61000-4-2 (±20 kV contact/air) and IEC 61000-4-5 (5.4 A surge) transients. It features 3.3 V reverse standoff voltage, 5.3 pF typical capacitance at 1 MHz, and clamps to ≤9 V at 5.4 A (8/20 µs), enabling use on high-speed USB 2.0 and HDMI interface lines.
For engineers reviewing the PESD3V3U1BCSF datasheet, PESD3V3U1BCSF pinout, PESD3V3U1BCSF application, or PESD3V3U1BCSF equivalent, key selection criteria include ultra-low clamping voltage under surge, sub-6 pF capacitance for minimal signal distortion, dual-cathode bidirectional topology, and compatibility with 0.4 mm pitch ultra-small PCB layouts in portable electronics.
Technical Context
This device implements a symmetric dual-diode clamp configuration with cathodes on both terminals (Pin 1 = K1, Pin 2 = K2), enabling bidirectional transient suppression without polarity constraints. Its low dynamic resistance (0.24 Ω typ.) ensures rapid voltage clamping during fast-rising ESD events (tr < 1 ns).
The DSN0603-2 package integrates both diodes into a single 0.6 mm × 0.3 mm × 0.3 mm leadless body with 0.4 mm pitch, optimized for placement directly at I/O connectors. It operates across –40 °C to +125 °C ambient, with junction temperature limited to 150 °C under surge stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 3.3 V reverse standoff voltage - blocks normal signal swing up to ±3.3 V while remaining non-conductive. |
| VCL @ 5.4 A | ≤9 V clamping voltage (8/20 µs) - limits transient overvoltage to safe levels for downstream 3.3 V logic interfaces. |
| Cd @ 1 MHz | 5.3 pF typical capacitance - preserves signal integrity on USB 2.0 (480 Mbps) and other high-speed digital lines. |
| ESD Rating | ±20 kV per IEC 61000-4-2 - withstands worst-case human-body-model discharges without degradation. |
| IRM | <1 nA reverse leakage at 3.3 V - avoids DC loading on sensitive analog or reference lines. |
| Package | DSN0603-2 (SOD962-2), 0.6 mm × 0.3 mm × 0.3 mm - enables ultra-dense routing near board edges and connectors. |
Pinout & Package
DSN0603-2 (SOD962-2) is a 2-terminal, leadless, ultra-small surface-mount package with 0.4 mm pitch and 0.3 mm height. Its compact footprint (0.6 mm × 0.3 mm) supports placement within 1 mm of I/O connectors for optimal ESD path inductance control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K1) | Forms first half of symmetrical clamp; connects to protected line when transient goes negative relative to ground. |
| 2 | Cathode (K2) | Forms second half of symmetrical clamp; conducts when transient goes positive relative to ground. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC-coupled or bipolar signal lines (e.g., USB D+/D–, HDMI TMDS) without polarity biasing. |
| Ultra-low capacitance | 5.3 pF typical ensures <0.5 dB insertion loss at 500 MHz - critical for maintaining eye diagram integrity in USB 2.0 links. |
| Sub-1 nA leakage | Prevents DC offset drift and battery drain in always-on portable device interfaces such as touch controllers or audio codecs. |
| 0.3 mm profile | Allows stacking beneath thin-film shields or under display bezels in smartphones and wearables where Z-height is constrained. |
Applications
| USB 2.0 Interface Protection | HDMI TMDS Line Protection |
|---|---|
|
Use Scenario: Protecting D+ and D– differential pairs in smartphone USB OTG ports from repeated electrostatic discharge during cable insertion. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed within 2 mm of USB connector, clamping ESD pulses before they reach the USB PHY. Use Value: Maintains 480 Mbps data rate by limiting capacitance to 5.3 pF and clamping transients to ≤9 V, preventing PHY latch-up or damage. |
Use Scenario: Shielding TMDS clock and data channels in portable media players against ESD during HDMI cable hot-plug events. IC Role / Device Role / Timing Role: Low-capacitance shunt clamp on each TMDS pair, positioned adjacent to HDMI receptacle to minimize loop inductance. Use Value: Preserves signal rise/fall times (<;300 ps) and reduces jitter accumulation via 5.3 pF loading and sub-10 V clamping at 5.4 A. |
| Smartphone Touch Interface | Wireless Headset Audio Lines |
|
Use Scenario: Guarding I²C-based capacitive touch controller lines (SDA/SCL) against ESD from user finger contact on glass overlay. IC Role / Device Role / Timing Role: Dual-cathode ESD diode connected between each I²C line and ground, leveraging bidirectional conduction for ±20 kV immunity. Use Value: Prevents false touch reporting and bus lockup by limiting leakage to <1 nA and ensuring no DC loading on 3.3 V I²C pull-ups. |
Use Scenario: Protecting analog audio paths (MIC_IN, HP_OUT) in Bluetooth headsets from ESD generated during earbud insertion/removal. IC Role / Device Role / Timing Role: Signal-line protector on unidirectional or bidirectional analog traces, placed immediately after jack connector pads. Use Value: Avoids audible pop/click artifacts by maintaining ≤5.3 pF capacitance and clamping transients before they couple into amplifier inputs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4105MR6T1G | Higher capacitance (12 pF typ.), higher clamping (12 V @ 5.4 A), SOT-563 package (1.6 mm × 1.2 mm) | Less suitable for >200 Mbps interfaces; larger footprint increases trace inductance | Select only if board space allows larger package and signal bandwidth is ≤100 Mbps. |
| Vishay VEML6030X01 | Photodiode sensor - not an ESD protector; incompatible function and pinout | Not applicable - misidentified part; excluded from ESD protection use cases | Avoid: functional mismatch confirmed via Vishay datasheet; not a valid alternative. |
Compared with NUP4105MR6T1G, PESD3V3U1BCSF delivers 57% lower capacitance and 33% lower clamping voltage in a package occupying 12% of the area - making it superior for space-constrained, high-speed portable interfaces where signal fidelity and layout density are critical.

FAQ
What is the maximum operating temperature for PESD3V3U1BCSF?
The device supports ambient operation from –40 °C to +125 °C, with a maximum junction temperature of 150 °C under surge conditions. Thermal derating is not required below 125 °C ambient, and its 0.3 mm height aids heat dissipation in thin-profile assemblies.
Can PESD3V3U1BCSF protect DC power rails?
No - this device is explicitly designed for signal-line protection only. The datasheet states it is "not designed to be used on lines connected to a DC supply." Its 3.3 V VRWM and low-power clamping architecture lack sustained power-handling capability for rail-level surges.
How does the dual-cathode configuration enable bidirectional protection?
Pin 1 (K1) and Pin 2 (K2) are both cathodes, forming two anti-parallel diodes sharing a common virtual anode node. When voltage on either pin exceeds 3.3 V above ground, that diode forward-biases and clamps; when driven negative, the other conducts - delivering symmetrical ±20 kV ESD immunity.
Is PESD3V3U1BCSF compliant with automotive AEC-Q200?
No - the Nexperia datasheet explicitly states this part is "non-automotive qualified" and "not suitable for automotive use." It lacks AEC-Q200 qualification testing, and its reliability data is specified only for commercial temperature range and consumer application contexts.
