Product details
Overview
PESD3V3V4UW from Nexperia is a unidirectional quadruple ESD protection diode array in SOT665 package, designed to protect four signal lines against electrostatic discharge up to 12 kV (IEC 61000-4-2 contact), with 3.3 V reverse standoff voltage, 15 pF typical diode capacitance at 0 V, and 11 V clamping voltage at 2 A pulse current. It is used in high-speed data interfaces of portable electronics and SIM card slots where low capacitance and fast transient response are critical.
For engineers reviewing the PESD3V3V4UW datasheet, PESD3V3V4UW pinout, PESD3V3V4UW application, or PESD3V3V4UW equivalent, key selection criteria include its 3.3 V VRWM rating, ultra-low 15 pF capacitance at 0 V, 1.5 A surge current capability per line (IEC 61000-4-5), 25 nA max reverse leakage at VRWM, and SOT665 5-pin flat-lead footprint for space-constrained PCB layouts.
Technical Context
This device implements four independent unidirectional ESD protection diodes sharing a common anode terminal (Pin 2), enabling compact protection of four unidirectional signal lines referenced to ground. Its architecture supports IEC 61000-4-2 level 4 (±12 kV contact) and IEC 61000-4-5 (1.5 A, 8/20 µs) compliance without signal distortion in high-frequency paths.
Clamping behavior is defined by a typical VCL of 9 V at 1 A and 11 V at 2 A, with differential resistance under 200 Ω and breakdown voltage of 5.6 V (typ). The 3.3 V VRWM ensures compatibility with 3.3 V logic systems while maintaining margin against normal operating transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 3.3 V - Maximum continuous reverse voltage before conduction; sets safe operating margin for 3.3 V I/O lines. |
| Cd (f = 1 MHz, VR = 0 V) | 15 pF (typ) - Low capacitance minimizes signal integrity degradation on USB, HDMI, or audio data lines. |
| VCL (IPP = 2 A) | 11 V - Clamping voltage limits transient overvoltage seen by downstream ICs during ESD events. |
| IPP (IEC 61000-4-5) | 1.5 A - Peak surge current handling per protected line using 8/20 µs waveform. |
| VESD (IEC 61000-4-2) | 12 kV (contact) - ESD immunity level ensuring robustness in handheld and consumer interface ports. |
| IRM (VRWM = 3.3 V) | 25 nA (max) - Ultra-low leakage preserves battery life and prevents false triggering in always-on circuits. |
| PPP (tp = 8/20 µs) | 16 W - Peak pulse power dissipation per diode, supporting repeated transient suppression without thermal failure. |
Pinout & Package
SOT665 is a 5-pin ultra-small surface-mount package with flat leads, measuring 1.7 × 1.5 × 0.5 mm (L × W × H), optimized for high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Protected signal line 1 input; connects to I/O trace requiring ESD clamping to common anode. |
| 2 | Common Anode | Shared return path to ground or system reference; must be routed with low-inductance connection. |
| 3 | Cathode (Diode 2) | Protected signal line 2 input; electrically isolated from other cathodes but shares anode node. |
| 4 | Cathode (Diode 3) | Protected signal line 3 input; enables simultaneous protection of three independent unidirectional lines. |
| 5 | Cathode (Diode 4) | Protected signal line 4 input; completes quad-channel configuration with single common anode. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional quad-diode architecture | Four independent cathodes + one shared anode enable compact, low-capacitance protection of four separate signal lines without cross-talk. |
| Ultra-low 15 pF capacitance (0 V) | Maintains signal integrity on high-speed interfaces (e.g., USB 2.0, SDIO) without bandwidth limiting or reflection. |
| 12 kV IEC 61000-4-2 contact ESD rating | Meets industrial and consumer end-equipment requirements for user-accessible ports without external shielding. |
| 1.5 A IEC 61000-4-5 surge capability | Withstands lightning-induced surges on communication lines such as SIM card interfaces or auxiliary audio jacks. |
| 25 nA max reverse leakage at 3.3 V | Minimizes standby current draw in battery-powered devices like smartphones and wearables. |
Applications
| USB 2.0 Data Lines | SIM Card Interface |
|---|---|
|
Use Scenario: Protection of D+ and D− lines in smartphone USB OTG ports against repeated plug/unplug ESD events. IC Role / Device Role / Timing Role: Unidirectional clamping diode array placed directly at connector, shunting transients to ground before reaching USB PHY. Use Value: 15 pF capacitance avoids signal rise-time degradation, while 11 V clamping prevents PHY latch-up during ±12 kV contact discharge. |
Use Scenario: ESD safeguarding of SIM VCC, I/O, CLK, and RST pins in mobile handsets exposed to frequent card insertion/removal. IC Role / Device Role / Timing Role: Quad-channel protector with common anode tied to system ground, providing coordinated clamping across all four SIM signals. Use Value: 3.3 V VRWM matches SIM interface voltage, and 25 nA leakage avoids disrupting low-power card detection circuitry. |
| Audio Jack Signals | Industrial Sensor Interface |
|
Use Scenario: Transient suppression on stereo headphone/mic TRRS lines in tablets and portable media players. IC Role / Device Role / Timing Role: Four-cathode diode array protecting left/right audio channels and mic bias line from human-body-model ESD. Use Value: Sub-20 pF capacitance preserves wideband audio fidelity up to 20 kHz without high-frequency roll-off or crosstalk. |
Use Scenario: Robust signal line protection for 4–20 mA or RS-485 sensor nodes deployed in factory-floor environments with high EMI exposure. IC Role / Device Role / Timing Role: Surge-absorbing component placed at PCB edge connector, diverting 1.5 A IEC 61000-4-5 surges away from analog front-end ICs. Use Value: 16 W peak pulse power rating ensures survivability during repetitive surge events without parameter drift or failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional quad-ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PESD3V3V4UG (SOT353) | Same electrical specs but SC-88A package (larger, 5-lead); 12 pF typ capacitance at 0 V vs. 15 pF. | Less suitable for ultra-dense layouts due to 2.2 × 1.35 mm footprint vs. SOT665's 1.7 × 1.5 mm. | Select when board real estate allows larger package and lower capacitance is prioritized over size. |
| ESD3V3ULV-2/TR (WeEn) | 3.3 V VRWM, 12 pF Cd, but dual-channel only (2 diodes); requires two devices for quad protection. | Increases BOM count and layout complexity; lacks integrated common-anode quad topology. | Choose only if supply chain constraints require WeEn sourcing and dual-device implementation is acceptable. |
Compared with PESD3V3V4UG, the PESD3V3V4UW offers superior board-area efficiency in identical electrical performance; versus ESD3V3ULV-2/TR, it delivers true quad integration with single-footprint simplicity and guaranteed channel matching.

FAQ
What is the maximum operating temperature for PESD3V3V4UW?
The junction temperature limit is 150 °C, and ambient operating range extends from −65 °C to +150 °C. Derating applies above 85 °C ambient per Figure 4 in the datasheet, where peak pulse power drops to 80 % of rated 16 W at 125 °C junction temperature.
Can PESD3V3V4UW protect bidirectional signal lines?
No - it is strictly unidirectional, with cathodes tied to protected lines and a common anode that must connect to ground or a fixed reference. For bidirectional protection, use a symmetrical dual-diode array like PESD5V0X1B or configure two PESD3V3V4UW devices back-to-back.
How does the SOT665 package affect PCB layout for optimal ESD performance?
SOT665's flat leads and small 1.7 × 1.5 mm body demand short, direct traces from connector pins to diode cathodes and a low-inductance ground connection to Pin 2. Layout guidelines specify ≤2 mm trace length, no vias in protection path, and dedicated ground pour under the device to minimize clamping impedance.
Is PESD3V3V4UW compliant with RoHS and REACH regulations?
Yes - Nexperia confirms full compliance with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, including SVHC screening. Lead-free reflow profile (J-STD-020) and halogen-free construction are standard for this part number.
