Product details
Overview
PESD3V3L2UM,315 from Nexperia is a unidirectional dual-line ESD protection diode in SOT883 package, featuring 3.3 V reverse standoff voltage, ≤28 pF capacitance at 0 V, <300 nA leakage at 3.3 V, 12 V clamping voltage at 3 A pulse, and IEC 61000-4-2 level 4 compliance (15 kV air/8 kV contact). It protects high-speed data lines in compact portable electronics.
For engineers reviewing the PESD3V3L2UM,315 datasheet, PESD3V3L2UM,315 pinout, PESD3V3L2UM,315 application, or PESD3V3L2UM,315 equivalent, key selection criteria include low capacitance for USB 2.0/MIPI D-PHY signal integrity, ultra-small footprint (1.17 mm²), dual-cathode/common-anode topology, and verified 3 A peak pulse current handling per diode path.
Technical Context
This device implements two independent unidirectional ESD protection paths sharing a common anode terminal, enabling simultaneous protection of two signal lines with minimal board area. Its SOT883 package uses three solder lands (1.0 × 0.6 × 0.5 mm) and supports FR4 PCB mounting with defined thermal resistance (290 K/W for one diode loaded).
Electrical behavior is characterized by sharp Zener-like breakdown at 5.6 V (typ), low differential resistance (200 Ω), and voltage-dependent capacitance-dropping from 22–28 pF at 0 V to 12–17 pF at 5 V reverse bias-critical for preserving signal rise time in >100 Mbps interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 3.3 V - Ensures no conduction during normal 3.3 V logic operation; defines maximum continuous line voltage before clamping initiates. |
| Clamping Voltage (IPP = 3 A) | 12 V - Limits transient overvoltage to safe levels for downstream 3.3 V ICs during 8/20 µs ESD events. |
| Diode Capacitance (f = 1 MHz, VR = 0) | 22–28 pF - Enables use on USB 2.0, HDMI, MIPI D-PHY, and other high-speed interfaces without signal distortion. |
| Leakage Current (VR = 3.3 V) | 75–300 nA - Prevents measurable DC loading on sensitive analog or low-power digital signal paths. |
| ESD Rating (IEC 61000-4-2) | 15 kV air / 8 kV contact - Meets industrial and consumer equipment immunity requirements without external circuitry. |
| Peak Pulse Current (8/20 µs) | 3 A per diode - Handles worst-case ESD transients while maintaining clamping performance across temperature. |
| Package | SOT883 - Ultra-compact 1.0 × 0.6 × 0.5 mm leadless package occupying only 1.17 mm² board area (≈10% of SOT23). |
Pinout & Package
SOT883 is a leadless ultra-small plastic package with three solderable terminals (1.0 × 0.6 × 0.5 mm body height), optimized for high-density PCB layouts and automated assembly. Thermal resistance is 290 K/W (one diode loaded) under standard FR4 conditions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 | Connects to first protected signal line; conducts ESD current to common anode during positive transients on Line 1. |
| 2 | Cathode 2 | Connects to second protected signal line; provides independent ESD path for Line 2 without crosstalk. |
| 3 | Common Anode | Shared return path to ground or supply rail; enables dual-line protection with single-point connection and minimal routing. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line unidirectional protection | Two independent cathodes share one anode-enables compact layout for differential pairs or parallel data buses without shared cathode coupling. |
| Low capacitance (22–28 pF @ 0 V) | Preserves signal integrity on 480 Mbps USB 2.0 and MIPI D-PHY interfaces; avoids timing skew or attenuation. |
| Ultra-low leakage (<300 nA @ 3.3 V) | Eliminates measurable DC offset or power drain in battery-powered sensor nodes and audio codec signal chains. |
| IEC 61000-4-2 level 4 certified | Validated 15 kV air / 8 kV contact ESD robustness-reduces need for system-level retesting and qualification delays. |
| SOT883 footprint (1.17 mm²) | Reduces PCB real estate by 90% vs. SOT23-critical for space-constrained designs like TWS earbuds and wearable sensors. |
Applications
| USB 2.0 Data Lines | MIPI D-PHY Interfaces |
|---|---|
|
Use Scenario: Protecting D+ and D− pins of USB 2.0 transceivers in smartphones and OTG adapters against user-handling ESD. IC Role / Device Role / Timing Role: Dual-cathode ESD clamp placed directly at connector, limiting transient voltage to <12 V during 3 A pulses without degrading 480 Mbps eye diagram. Use Value: Maintains USB 2.0 compliance without adding series resistance or RC filtering; eliminates post-assembly failure due to connector discharge. |
Use Scenario: Shielding high-speed camera sensor interface (CSI-2) in mobile devices from ESD during flex cable mating/unmating. IC Role / Device Role / Timing Role: One PESD3V3L2UM,315 protects both clock and data lanes of a MIPI D-PHY lane pair, leveraging matched capacitance (<28 pF) to preserve skew tolerance. Use Value: Prevents pixel corruption or frame drop caused by ESD-induced latch-up in image sensor SoCs, validated per JEDEC JESD22-A114F. |
| Audio Codec Line Inputs | Industrial Sensor Signal Conditioning |
|
Use Scenario: Guarding analog audio inputs (e.g., headset mic jack) in portable media players against human-body-model ESD events. IC Role / Device Role / Timing Role: Unidirectional clamp referenced to AVDD (3.3 V), blocking negative transients while allowing full-scale ±1 V AC audio swing. Use Value: Avoids audible pop/click artifacts and ADC saturation during plug insertion; leakage <300 nA prevents DC bias shift in op-amp front-end. |
Use Scenario: Protecting 4–20 mA current-loop sensor outputs in factory automation modules exposed to maintenance personnel ESD. IC Role / Device Role / Timing Role: Cathode-to-signal, anode-to-ground configuration safeguards loop driver output against contact discharge without affecting 24 V loop compliance. Use Value: Ensures uninterrupted sensor reporting during field servicing; clamping voltage <12 V prevents damage to precision DACs and isolation amplifiers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z3.3T5G (onsemi) | Higher capacitance (35 pF @ 0 V); same 3.3 V VRWM; SOD-523 package (1.3 × 0.85 × 0.7 mm) | Larger footprint (1.105 mm² vs. 1.17 mm²) and higher Cd limit use to ≤100 Mbps interfaces | Select when cost sensitivity outweighs high-speed signal integrity needs; verify layout clearance for SOD-523 thermal pad. |
| TPD2E001DRYR (TI) | Bidirectional configuration; 10 pF @ 0 V; 5.5 V VRWM; same SOT-563 package size but different pinout (anode on pin 6) | Requires redesign for unidirectional biasing; lower Cd suits USB 3.0 but 5.5 V VRWM risks false triggering on 3.3 V rails | Prefer only if bidirectional protection is required and system rail tolerances allow 5.5 V standoff. |
Compared with ESD5Z3.3T5G and TPD2E001DRYR, PESD3V3L2UM,315 delivers optimal balance of low capacitance, precise 3.3 V standoff, and minimal footprint-making it preferred for space-constrained, high-speed 3.3 V interfaces where unidirectional clamping suffices.

FAQ
What is the maximum operating temperature for PESD3V3L2UM,315?
The junction temperature rating is 150 °C, and the storage temperature range is −65 °C to +150 °C. Under continuous 250 mW total power dissipation at 25 °C ambient, thermal resistance (290 K/W for one diode) limits steady-state junction rise to ~72.5 °C-well within safe margin for handheld device operation.
Can PESD3V3L2UM,315 protect bidirectional signal lines like I²C?
No-it is a unidirectional device with cathodes on pins 1 and 2 and a common anode on pin 3, suitable only for signals referenced to a fixed rail (e.g., USB D+/D− to GND). For bidirectional buses such as I²C, a symmetric bidirectional ESD diode like PESD5V0S1BA,315 is required.
How does the 12 V clamping voltage at 3 A affect downstream 3.3 V ICs?
The 12 V clamping voltage occurs only during sub-100 ns ESD transients and is not sustained. Downstream 3.3 V ICs with 5 V absolute maximum ratings (common in USB PHYs and SerDes blocks) tolerate this brief overvoltage without damage, as confirmed by IEC 61000-4-2 testing.
Is the SOT883 package compatible with standard reflow profiles?
Yes-the SOT883 package is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 and supports standard Pb-free reflow profiles (peak 260 °C, 20–40 s above 217 °C), with thermal pad design guidelines provided in Nexperia's SOT883 mounting specification.
