Product details
Overview
IP4302CX2/LF,315 from Nexperia is a bidirectional ESD protection diode designed for single-line signal integrity in space-constrained portable electronics. It delivers ±15 kV IEC 61000-4-2 contact discharge protection, features 10 pF capacitance at 1 MHz, 16.5 V typical breakdown voltage, and resides in a 0.52 mm × 0.7 mm WLCSP2 package with 0.40 mm height - enabling robust ESD hardening of SIM card interfaces and high-speed data lines.
For engineers reviewing the IP4302CX2/LF,315 datasheet, IP4302CX2/LF,315 pinout, IP4302CX2/LF,315 application, or IP4302CX2/LF,315 equivalent, this device serves as a low-capacitance, ultra-thin ESD clamp for bidirectional signal paths where PCB real estate and signal fidelity are critical - especially in mobile handset front-end protection and compact peripheral interfaces.
Technical Context
The IP4302CX2/LF,315 integrates two back-to-back silicon diodes monolithically in a wafer-level chip-scale package, forming a symmetrical bidirectional clamping structure. Its electrical symmetry eliminates polarity marking requirements and supports AC-coupled or dual-polarity signal lines without orientation constraints.
It operates within −35 °C to +85 °C ambient range and withstands junction temperatures up to 150 °C. The device is qualified for ≥1000 ±15 kV contact discharges per IEC 61000-4-2, exceeding Level 4 (±8 kV), and exhibits only 20 nA reverse leakage at ±5 V.

Pinout & Package
IP4302CX2/LF,315 uses a 2-bump Wafer-Level Chip-Scale Package (WLCSP2) with A1–A1 bump layout. The device is electrically and mechanically symmetrical - no polarity marking required, and either bump may serve as cathode for one diode branch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Forms one half of the back-to-back pair; connects to protected line when used in standard configuration |
| 2 | Cathode (Diode 2) | Completes bidirectional path; ties to ground reference to enable clamping during both positive and negative ESD events |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD Clamping | Back-to-back diode architecture protects AC or dual-polarity signals without directionality concerns |
| Ultra-Low Capacitance | 10 pF ensures minimal signal distortion on high-frequency lines such as SIM clock/data or audio codec interfaces |
| Wafer-Level Packaging | WLCSP2 footprint reduces parasitic inductance and improves transient response vs. SOT or SC-70 alternatives |
| Pb-Free & Halogen-Free | RoHS-compliant and Dark Green certified; meets global environmental compliance for consumer electronics |
| High ESD Robustness | Qualified for ≥1000 ±15 kV contact discharges - supports long-term reliability in high-touch consumer devices |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z3.3T5G | 3.3 V working voltage; lower clamping voltage but higher 25 pF capacitance | Better for low-voltage logic (1.8–3.3 V), less suitable for 5 V tolerant SIM or USB lines | Select when protecting sub-3.6 V I/O with tighter voltage margins; verify signal bandwidth impact from higher capacitance |
| TPD2E001DRYR | Two-channel array in 1.0 mm × 0.6 mm DRY package; 12 pF per channel, ±12 kV ESD rating | Offers dual-line protection in same footprint; lower ESD rating than IP4302CX2/LF,315's ±15 kV | Choose for multi-line protection consolidation; accept reduced ESD margin if board space permits larger package |
Compared with ESD5Z3.3T5G and TPD2E001DRYR, IP4302CX2/LF,315 provides the highest IEC 61000-4-2 contact discharge rating (±15 kV) in the smallest footprint (0.52 mm × 0.7 mm), making it optimal for single-line protection where ultimate miniaturization and maximum ESD margin are jointly required.

FAQ
What is the primary function of the IP4302CX2/LF,315?
The IP4302CX2/LF,315 is a bidirectional ESD protection diode designed to safeguard single-ended signal lines from electrostatic discharge events. It clamps transient voltages up to ±15 kV (contact discharge, IEC 61000-4-2) while adding only 10 pF capacitance - ensuring signal integrity on high-speed or low-voltage interfaces like SIM cards and USB data lines. Its WLCSP2 package enables placement directly at connectors.
Does the IP4302CX2/LF,315 require orientation during PCB placement?
No - the IP4302CX2/LF,315 is electrically and mechanically symmetrical, with identical bumps labeled Pin 1 and Pin 2 serving as cathodes for opposing diodes. This symmetry eliminates polarity marking and orientation dependency, simplifying automated assembly and reducing placement error risk. The device functions identically regardless of rotational alignment on the PCB.
What is the maximum operating temperature for the IP4302CX2/LF,315?
The IP4302CX2/LF,315 supports an ambient operating temperature range of −35 °C to +85 °C, with a maximum junction temperature of 150 °C. This range aligns with commercial and industrial portable equipment requirements. Thermal performance is enhanced by its WLCSP2 package, which offers low thermal resistance to the PCB via direct bump attachment.
Can the IP4302CX2/LF,315 be used for USB 2.0 data line protection?
Yes - the IP4302CX2/LF,315 is suitable for USB 2.0 D+ and D− line protection due to its 10 pF capacitance (at 1 MHz, 0 V), which minimizes signal distortion at 480 Mbps data rates, and its ±15 kV ESD rating, which exceeds USB-IF recommended immunity levels. It must be placed within 2 mm of the USB receptacle with short, low-inductance ground paths for optimal performance.
Is the IP4302CX2/LF,315 RoHS and halogen-free compliant?
Yes - the IP4302CX2/LF,315 is Pb-free, RoHS compliant, and fully halogen- and antimony-free, meeting Nexperia's "Dark Green" environmental standard. This compliance supports global market access for consumer electronics, including EU WEEE and China RoHS requirements, without compromising ESD performance or package miniaturization.
