Product details
Overview
BAT54LS-QYL 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 automotive-grade circuits. It delivers 400 mV forward voltage at 10 mA, 5 ns reverse recovery time, 10 pF capacitance at 1 V, and supports 30 V reverse voltage and 200 mA continuous forward current.
For engineers reviewing the BAT54LS-QYL datasheet, BAT54LS-QYL pinout, BAT54LS-QYL application, or BAT54LS-QYL equivalent, this device is selected for low-loss signal path protection, compact AOI-compatible layout, and AEC-Q101-qualified operation in engine control units, ADAS sensor interfaces, and power rail clamp networks.
Technical Context
This Schottky diode uses a planar silicon structure with optimized metal-semiconductor junction to minimize forward voltage drop while maintaining low leakage and fast transient response. Its side-wettable flanks enable reliable solder joint inspection on automated assembly lines.
The device operates within −55 °C to 150 °C ambient range, with thermal resistance of 360 K/W (free air) and 195 K/W (1 cm² copper pad), supporting high-density PCB layouts where thermal management and space constraints are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - Maximum blocking capability without breakdown in clamping or reverse-biased protection paths. |
| Forward Voltage (VF) | 400 mV @ 10 mA - Enables low-loss voltage translation and minimal conduction loss in signal-level switching. |
| Reverse Recovery Time (trr) | 5 ns - Supports >100 MHz switching in RF detector, sample-and-hold, and high-frequency clamp circuits. |
| Diode Capacitance (Cd) | 10 pF @ 1 V - Limits signal distortion and loading in high-speed data line protection and RF front-end applications. |
| Forward Current (IF) | 200 mA continuous - Sustains stable operation in power rail snubbing and low-power supply OR-ing functions. |
| Junction Temperature (Tj) | 150 °C - Allows deployment in under-hood automotive modules without derating at full load. |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a 2-terminal, leadless ultra-small surface-mount package measuring 1.0 mm × 0.6 mm × 0.47 mm with side-wettable flanks for AOI-compliant solder joint verification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative terminal; connects to higher-potential node in clamping configuration or output side in rectifier use. |
| 2 | Anode (A) | Positive terminal; ties to lower-potential node or signal source in protection topology. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 400 mV at 10 mA enables efficient signal-level clamping with <100 mW dissipation in typical use cases. |
| Ultra-fast recovery | 5 ns trr ensures minimal tail current during polarity reversal, critical for high-frequency sampling and pulse shaping. |
| Side-wettable flanks | Enables automated optical inspection of solder joints without X-ray, reducing post-reflow defect escape in automotive production. |
| AEC-Q101 qualification | Validated for automotive applications including engine control, body electronics, and infotainment power domains. |
Applications
| Engine Control Unit (ECU) Signal Protection | ADAS Camera Interface Clamping |
|---|---|
Use Scenario: Protecting CAN/LIN transceiver I/O pins from ESD and load dump transients in under-hood ECUs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed between transceiver and connector, conducting only during overvoltage events. Use Value: 30 V VR rating and 5 ns trr prevent latch-up and ensure signal integrity during 100 ns–1 µs transients per ISO 7637-2. |
Use Scenario: Clamping differential video signals (e.g., GMSL, FPD-Link III) at camera module input to suppress EMI-induced overshoot. IC Role / Device Role / Timing Role: Low-capacitance shunt element across signal pair, activated only above common-mode threshold. Use Value: 10 pF Cd minimizes high-frequency attenuation; 400 mV VF ensures clamping threshold remains below receiver input limits. |
| USB Type-C Port Power Path OR-ing | Automotive Infotainment Display Backlight Control |
Use Scenario: OR-ing two 5 V power sources (e.g., USB PD and battery) to drive a single load with automatic source selection. IC Role / Device Role / Timing Role: Low-VF forward path switch enabling seamless switchover without voltage droop or reverse current flow. Use Value: 200 mA IF rating and 400 mV VF reduce insertion loss and thermal rise in compact portable designs. |
Use Scenario: Reverse-polarity protection and flyback energy suppression for LED driver IC outputs feeding segmented display backlights. IC Role / Device Role / Timing Role: Freewheeling path for inductive kickback during PWM dimming transitions. Use Value: 600 mA IFSM withstands repetitive 10 ms pulses; 5 ns trr prevents cross-conduction in high-frequency PWM (>1 kHz). |

FAQ
What is the marking code for BAT54LS-QYL?
The BAT54LS-QYL is marked with "8L" on the top surface of the DFN1006BD-2 package, located adjacent to the cathode-side marking bar. This code is consistent across all production lots and aligns with Nexperia's standard SOD882BD marking convention per Table 4 of the datasheet.
Can BAT54LS-QYL replace BAT54C in an existing design?
No - BAT54LS-QYL is a single-diode variant in DFN1006BD-2, whereas BAT54C is a dual-common-cathode configuration in SOT23. Pin count, package footprint, and internal topology differ fundamentally; direct substitution would require PCB and schematic revision.
Is BAT54LS-QYL suitable for reflow soldering with lead-free paste?
Yes - the DFN1006BD-2 package is qualified for standard lead-free reflow profiles (J-STD-020 compliant), with peak temperature up to 260 °C. Figure 8 in the datasheet provides the recommended solder land pattern and stencil aperture dimensions for optimal wetting and void control.
What is the thermal resistance when mounted on a 1 cm² copper pad?
When mounted on an FR4 PCB with a 1 cm² cathode-side copper pad (70 μm thickness, tin-plated), the typical thermal resistance from junction to ambient (Rth(j-a)) is 195 K/W, as specified in Table 6 of the datasheet under condition [3].
