Product details
Overview
IP4387CX4/P,315 from NXP Semiconductors is a single-channel integrated ESD protection diode in a 2×2 Wafer Level Chip-Scale Package (WLCSP) with 0.4 mm pitch, rated for ±30 kV contact ESD per IEC 61000-4-2 level 4, 8.0 V reverse standoff voltage (VRWM), and 13 V clamping voltage (VCL) at 1 A surge current-designed for polarity reversal and transient suppression on USB/charger interface lines in portable electronics.
For engineers reviewing the IP4387CX4/P,315 datasheet, IP4387CX4/P,315 pinout, IP4387CX4/P,315 application, or IP4387CX4/P,315 equivalent, this device delivers verified high-energy surge immunity (33 A IEC 61000-4-5), low 290 pF capacitance for signal integrity, and compact 0.76 × 0.76 × 0.61 mm WLCSP footprint-critical for space-constrained mobile handset and wireless data system designs.
Technical Context
This device implements a monolithic silicon diode structure optimized for bidirectional ESD clamping, with cathode and anode each connected to two solder balls for low-inductance PCB routing. Its thermal resistance (Rth(j-a) = 130 K/W) assumes a heat-dissipation-optimized 2-layer PCB with micro-vias to buried ground plane.
It operates across −30 °C to +85 °C ambient temperature, supports Pb-free reflow up to 260 °C peak, and maintains stable reverse leakage (<800 nA at VR = +8 V) and forward voltage (1.10–1.25 V at IF = 850 mA) over full temperature range-enabling reliable DC polarity protection and fast transient response.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IP4386CX4/P | Higher VRWM (+14 V), higher VCL (20 V), lower Cd (160 pF), same package | Better suited for 12 V supply rails; less suitable for 5 V USB due to elevated clamping | Select IP4386CX4/P only when protecting >10 V lines where tighter capacitance control is critical |
| IP4385CX4/LF | Lower VRWM (+5.5 V), lower VCL (10 V), higher Cd (450 pF), 0.5 mm pitch WLCSP | Optimized for 3.3 V logic; incompatible pin pitch prevents direct PCB reuse | Choose IP4385CX4/LF for low-voltage, high-capacitance-tolerant interfaces-requires layout revision |
Compared with IP4386CX4/P and IP4385CX4/LF, IP4387CX4/P,315 uniquely balances 8 V operating margin, 13 V clamping, and 290 pF loading-making it the optimal choice for 5 V USB/charger interfaces where both voltage headroom and signal fidelity matter.

FAQ
What is the maximum continuous reverse standoff voltage for IP4387CX4/P,315?
The IP4387CX4/P,315 has a reverse standoff voltage (VRWM) of +8.0 V, meaning it remains non-conductive up to this DC or steady-state voltage on the protected line. This rating ensures compatibility with standard 5 V USB power rails while providing sufficient margin against ripple and tolerance drift-verified per Table 3 in the NXP datasheet Rev. 2 (2012).
Does IP4387CX4/P,315 support Pb-free reflow soldering?
Yes, IP4387CX4/P,315 is qualified for Pb-free reflow with a peak temperature of up to 260 °C (per Table 10), and withstands at least three reflow cycles using the profile shown in Figure 18. Its WLCSP4 package uses AuNi copper finish and is compatible with SnAgCu solder paste-fully compliant with JEDEC J-STD-020D moisture sensitivity level 1.
How many ESD strikes can IP4387CX4/P,315 survive at ±30 kV contact discharge?
The IP4387CX4/P,315 is tested with over 1000 pulses of ±30 kV contact discharge per IEC 61000-4-2 (footnote [1] in Table 3), confirming robust endurance beyond industrial requirements. Performance retention-including clamping voltage stability and leakage current-is validated post-stress under specified ambient conditions.
What is the thermal resistance (Rth(j-a)) of IP4387CX4/P,315, and under what conditions is it measured?
IP4387CX4/P,315 has a typical junction-to-ambient thermal resistance (Rth(j-a)) of 130 K/W, measured on a 2-layer PCB with optimized heat dissipation-specifically using NSMD pads, laser-drilled micro-vias to a buried ground plane, and massive copper area under the device (per Table 4 and Section 9.1). This value assumes natural convection, not forced airflow.
Can IP4387CX4/P,315 be used for wrong-polarity protection in addition to ESD suppression?
Yes, IP4387CX4/P,315 provides DC clamping for wrong-polarity faults, with forward current DC clamping voltage characterized across temperature (Figure 5). At 850 mA and +25 °C, VF is 1.10–1.25 V-enabling safe current limiting during reverse-connection events on 5 V supply lines without damaging downstream circuitry.
