Product details
Overview
BAT54LSYL from Nexperia is a planar Schottky barrier diode in a leadless DFN1006BD-2 (SOD882BD) package, designed for ultra-high-speed switching and voltage clamping in space-constrained PCBs. It delivers 800 mV forward voltage at 100 mA, 2 µA reverse leakage at 25 V, 10 pF capacitance at 1 V, 5 ns reverse recovery time, and operates across –55 °C to 150 °C ambient.
For engineers reviewing the BAT54LSYL datasheet, BAT54LSYL pinout, BAT54LSYL application, or BAT54LSYL equivalent, key selection criteria include low VF for power efficiency, ultra-small SWF package for AOI-compatible high-density layouts, fast trr for signal integrity in RF/USB protection, and thermal performance on FR4 with side-wettable flanks.
Technical Context
This Schottky diode uses a planar metal–semiconductor junction to achieve near-zero minority-carrier storage, enabling nanosecond-scale switching without reverse recovery tail. Its low 0.47 mm profile and side-wettable flanks support automated optical inspection and reliable reflow soldering on fine-pitch layouts.
The device is rated for 30 V reverse voltage and 200 mA continuous forward current, with pulsed capability up to 600 mA. Thermal resistance is 360 K/W (standard footprint) or 195 K/W (1 cm² cathode pad), reflecting its dependence on PCB copper layout for thermal management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 100 mA | 800 mV - Enables low-loss clamping in 3.3 V and 5 V logic rails with minimal conduction heating |
| IR @ 25 V | 2 µA - Ensures negligible leakage in battery-backed or high-impedance bias networks |
| trr | 5 ns - Supports >100 MHz switching in RF front-end protection and USB 2.0 data line clamping |
| Cd @ 1 V | 10 pF - Minimizes signal distortion in high-speed digital and analog signal path applications |
| VR | 30 V - Suitable for 24 V industrial I/O protection and 12 V automotive body electronics |
| Tj max | 150 °C - Allows operation in under-hood or enclosed industrial enclosures without derating |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a 2-terminal, leadless ultra-small plastic package measuring 1.0 mm × 0.6 mm × 0.47 mm, with side-wettable flanks for AOI-compatible solder joint verification and 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to higher-potential node during clamping; marked by bar on top surface |
| 2 | Anode (A) | Connected to lower-potential node or ground reference; enables forward conduction when A < K |
Key Features
| Feature | Design Value |
|---|---|
| Low VF | 800 mV at 100 mA reduces power loss by >40% vs. standard silicon diodes in 3.3 V rail clamping |
| Ultra-small footprint | 1.0 mm × 0.6 mm saves >70% board area vs. SOT23, critical for wearables and miniaturized IoT sensors |
| Side-wettable flanks | Enables automated optical inspection of solder fillets without X-ray, improving manufacturing yield in high-volume SMT lines |
| Low capacitance | 10 pF at 1 V preserves signal edge rate in USB 2.0 and HDMI hot-plug detection circuits |
Applications
| USB 2.0 ESD Protection | Industrial Sensor Signal Clamping |
|---|---|
Use Scenario: Bidirectional clamping of D+ and D− lines against ±8 kV contact ESD per IEC 61000-4-2. IC Role / Device Role / Timing Role: Passive voltage clamp placed between connector and transceiver IC, conducting only during overvoltage events. Use Value: 5 ns trr prevents data corruption during fast transients; 10 pF Cd avoids signal integrity degradation at 480 Mbps. |
Use Scenario: Protecting 0–10 V analog sensor outputs from induced surges in factory automation cabinets. IC Role / Device Role / Timing Role: Low-leakage shunt clamp referenced to system ground, limiting output swing to safe ADC input range. Use Value: 2 µA IR ensures <0.1 mV offset error in 12-bit precision systems; 800 mV VF sets precise 3.3 V clamp threshold. |
| Low-Voltage Logic Level Shifting | DC-DC Converter Output Snubbing |
Use Scenario: Biasing level-shift networks in battery-powered microcontrollers interfacing with 1.8 V peripherals. IC Role / Device Role / Timing Role: Forward-biased Schottky used as low-drop voltage translator in open-drain pull-up configurations. Use Value: 320 mV VF at 1 mA enables accurate 1.8 V → 3.3 V translation without active circuitry or additional supply rails. |
Use Scenario: Suppressing ringing and voltage spikes at synchronous buck converter output during light-load discontinuous conduction mode. IC Role / Device Role / Timing Role: Fast-recovery snubber diode placed across LC filter to absorb high-frequency energy. Use Value: 5 ns trr captures sub-100 ns oscillations; 30 V VR rating covers typical 24 V industrial DC-DC outputs with margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky barrier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR0230HT1G | Higher VF (370 mV typ @ 10 mA), same 30 V VR, but larger SOD-323 package (1.7 mm × 1.3 mm) | Less suitable for ultra-dense layouts; better thermal dissipation on large pads | Select when board space allows and higher pulsed current (500 mA) is required over compactness |
| Diodes Incorporated SD103AWS-7-F | Lower VR (20 V), higher Cd (25 pF), same DFN1006 package but no side-wettable flanks | Not AOI-verified; unsuitable for 24 V systems or >100 MHz signal paths | Choose only for cost-sensitive 3.3 V-only applications where solder joint inspection is manual |
Compared with NSR0230HT1G and SD103AWS-7-F, BAT54LSYL uniquely balances ultra-small size, AOI compatibility, and 30 V/5 ns performance-making it optimal for next-gen USB-C accessories and miniaturized industrial controllers where layout density and automated assembly are non-negotiable.

FAQ
What is the maximum continuous forward current for BAT54LSYL?
The BAT54LSYL supports 200 mA continuous forward current at Tamb ≤ 25 °C, derating linearly to zero at 150 °C junction temperature. This rating assumes mounting on an FR4 PCB with single-sided 70 μm copper and standard footprint per datasheet condition [1]. Exceeding this requires thermal modeling using Rth(j-a) = 360 K/W.
Does BAT54LSYL have automotive qualification?
No, BAT54LSYL is not AEC-Q200 qualified. Nexperia explicitly states in its legal disclaimers that unless otherwise specified, products like BAT54LSYL are non-automotive qualified and not tested to automotive reliability or environmental standards. It is intended for industrial, computing, and consumer applications.
How is the cathode identified on the BAT54LSYL package?
The cathode is marked by a visible bar on the top surface of the DFN1006BD-2 package, aligned with Pin 1. The transparent top view in the datasheet confirms Pin 1 as K (cathode) and Pin 2 as A (anode), with the marking code "8L" laser-etched adjacent to the bar.
Can BAT54LSYL be used in bidirectional ESD protection configurations?
Yes-BAT54LSYL is commonly deployed in dual-diode arrangements (e.g., with a second BAT54LSYL or complementary device) to provide symmetrical ±V clamp behavior. Its 5 ns trr and low capacitance make it suitable for bidirectional transient suppression on differential pairs such as USB D+/D−, provided external series impedance limits peak current.
