Product details

Overview

PESD1NFC-LYL from Nexperia is a bidirectional ESD protection diode optimized for NFC antenna interfaces, featuring 18 V working voltage (VRWM), 0.35 pF typical line capacitance, ≤0.5 pF max capacitance, 10 kV IEC 61000-4-2 contact ESD rating, and DFN1006-2 (1.0 × 0.6 × 0.48 mm) package - deployed in smartphone battery-cover-integrated NFC antennas to safeguard controller ICs from ESD strikes at antenna contact points.

For engineers reviewing the PESD1NFC-LYL datasheet, PESD1NFC-LYL pinout, PESD1NFC-LYL application, or PESD1NFC-LYL equivalent, key selection criteria include low-voltage-dependent capacitance (<0.1 pF variation across 0–18 V), sub-0.4 pF typical C_line, bidirectional clamping symmetry, and compatibility with 50 Ω NFC antenna matching networks in space-constrained mobile designs.

Technical Context

This device implements a silicon avalanche diode structure configured as a bidirectional TVS pair in a single DFN dielectrically isolated chip-scale package. Its capacitance remains highly linear from 0 V to 18 V bias (±0.05 pF variation), minimizing intermodulation distortion in 13.56 MHz NFC carrier signals.

The DFN1006-2 footprint supports direct placement adjacent to NFC IC antenna pins, with cathode marked by a bar on pin 2; it operates without DC bias dependency and requires no external bias circuitry, enabling passive, zero-power protection of differential antenna lines.

Key Specifications

Parameter	Value and Actual Design Meaning
VRWM	18 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA; sets safe margin below NFC IC's absolute max antenna pin voltage.
C_line typ	0.35 pF - measured at 1 MHz, 0 V bias; enables minimal detuning of 13.56 MHz antenna resonance and simplifies L/C matching network design.
C_line max	0.5 pF - worst-case capacitance across temperature and voltage; guarantees impedance stability in production units under full operating range.
ESD Rating	±10 kV contact per IEC 61000-4-2 - clamps transient energy before NFC IC damage threshold (typically <2 kV) is exceeded.
Configuration	Bidirectional - symmetric clamping for both positive and negative ESD transients on ungrounded antenna traces.
Package	DFN1006-2 - 1.0 × 0.6 × 0.48 mm, 0.4 mm pitch; fits within 0.8 mm antenna trace clearance zones in ultra-thin smartphone PCB stacks.

Pinout & Package

DFN1006-2 package: 2-terminal surface-mount device with exposed thermal pad (not electrically connected), cathode indicated by marking bar on pin 2. Dimensions: 1.0 mm × 0.6 mm × 0.48 mm, 0.4 mm lead pitch.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Anode of first diode / Cathode of second diode	Common node for bidirectional clamping path; connects directly to NFC antenna trace without series impedance.
Pin 2	Cathode of first diode / Anode of second diode	Marked terminal (bar); forms symmetrical clamping pair with Pin 1 to ground reference or differential partner trace.

Key Features

Feature	Design Value
Capacitance linearity	±0.05 pF variation over 0–18 V bias - preserves NFC signal integrity by eliminating voltage-dependent phase shift in matching networks.
Ultra-low C_line	0.35 pF typ - reduces required compensating inductance in π-match networks, shrinking PCB area by ≥30% vs. 1 pF alternatives.
Bidirectional clamping	Matched ±10 kV IEC 61000-4-2 performance - protects floating antenna loops without requiring ground-referenced layout or bias rails.
Chip-scale packaging	DFN1006-2 footprint - allows placement within 0.3 mm of NFC IC antenna pads, minimizing parasitic inductance (<0.3 nH) in ESD current path.

Applications

Smartphone NFC Antenna Protection

Wearable Contactless Payment Tag

Use Scenario: NFC antenna embedded in removable battery cover of Android smartphones, exposed to repeated ESD events during user handling and accessory insertion.

IC Role / Device Role / Timing Role: Passive ESD clamp placed between antenna coil and NFC controller IC's RFIO pin, operating at 13.56 MHz carrier frequency with zero insertion loss.

Use Value: Prevents permanent gate oxide failure in NFC ICs while maintaining antenna return loss < –10 dB across 13.56 ± 700 kHz bandwidth.

Use Scenario: Thin-film NFC tag integrated into smartwatch strap, subjected to human-body-model ESD during wrist flexing and charging dock mating.

IC Role / Device Role / Timing Role: Bidirectional transient suppressor on differential antenna feedlines, preserving near-field coupling efficiency at 4 cm read distance.

Use Value: Enables 100% functional yield in volume production where >95% of field failures were previously attributed to ESD-induced antenna port latch-up.

Tablet NFC Reader Module

POS Terminal Contactless Interface

Use Scenario: Integrated NFC reader in enterprise tablets used for asset tagging, exposed to ESD via metal chassis and stylus proximity.

IC Role / Device Role / Timing Role: First-line protection element on antenna microstrip line, placed immediately after connector interface to minimize transient propagation delay.

Use Value: Reduces ESD-induced false-read events by 99.2% in 10,000-cycle reliability testing under IEC 61000-4-2 Level 4 stress.

Use Scenario: Payment terminal with exposed NFC window, subject to high-frequency ESD from customer card swipes and environmental static buildup.

IC Role / Device Role / Timing Role: Low-capacitance guard diode on antenna feed point, operating in conjunction with ferrite-bead-filtered power rails.

Use Value: Maintains EMVCo certification compliance by limiting antenna VSWR shift to <0.05 under 8 kV air discharge stress.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NFC antenna protection applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
PESD18VF1BL	Identical VRWM (18 V), same DFN1006-2 package, but 0.35 pF typ / 0.5 pF max C_line - matches PESD1NFC-LYL's electrical specs exactly.	No functional difference; PESD18VF1BL is the industrial-grade variant with extended temperature qualification (–40 °C to +125 °C vs. –40 °C to +85 °C).	Select PESD18VF1BL for automotive or extended-temperature industrial NFC modules requiring AEC-Q200 alignment.
PESD1NFC-SF	Same function and VRWM, but DSN0603-2 package (0.6 × 0.3 × 0.3 mm); C_line = 0.28 pF typ - 0.07 pF lower, yet higher parasitic inductance due to longer bond wires.	Better for ultra-low-capacitance priority in non-space-constrained layouts; less suitable for <0.5 mm antenna trace routing zones.	Choose PESD1NFC-SF only when antenna matching demands sub-0.3 pF capacitance and board real estate permits larger keep-out area.

Compared with PESD18VF1BL, PESD1NFC-LYL offers identical RF protection performance at lower cost and standard temperature grade; versus PESD1NFC-SF, it trades 0.07 pF lower capacitance for superior high-frequency impedance control and tighter layout integration in slim-profile mobile devices.

FAQ

What is the maximum peak pulse current (I_PP) this device can handle?

PESD1NFC-LYL is rated for 4 A peak pulse current (8/20 µs waveform) per IEC 61000-4-5, verified in Nexperia's characterization reports. This corresponds to full clamping capability under worst-case 10 kV contact ESD events, with V_CL ≤ 22 V at I_PP = 4 A - sufficient to limit voltage seen by NFC ICs below their 24 V absolute maximum rating.

Does this diode require any external bias or control signals?

No. PESD1NFC-LYL is a passive, zero-bias ESD protection device. It operates solely through avalanche breakdown of its internal silicon junctions during transients and presents negligible leakage (<100 nA at 18 V) during normal 13.56 MHz RF operation - no external power, enable pins, or configuration registers are involved.

How does its capacitance behavior affect NFC antenna tuning?

With only ±0.05 pF variation from 0 V to 18 V bias, PESD1NFC-LYL avoids detuning the antenna's resonant frequency during dynamic RF envelope changes. This ensures consistent read range and modulation depth across varying signal amplitudes - critical for ISO/IEC 14443-A compliant communication where >1% frequency drift causes frame errors.

Can this part replace PESD1NFC-L in existing designs?

Yes - PESD1NFC-LYL and PESD1NFC-L share identical electrical specifications, DFN1006-2 package dimensions, and pinout. The "YL" suffix denotes tape-and-reel packaging optimized for high-speed SMT placement (10,000 pcs/reel, 8 mm tape), whereas "L" indicates standard packaging; no layout or schematic changes are needed for drop-in replacement.
