Product details
Overview
BAT46LS-QYL from Nexperia is a general-purpose Schottky diode in a DFN1006BD-2 (SOD882BD) ultra-small leadless package, rated for 100 V reverse voltage, 250 mA forward current, and featuring 3 µA reverse leakage at 75 V. It delivers low forward voltage (960 mV at 150 mA), low capacitance (25 pF at 0 V), and 3 ns reverse recovery time-optimized for high-speed switching and reverse polarity protection in automotive power rails.
For engineers reviewing the BAT46LS-QYL datasheet, BAT46LS-QYL pinout, BAT46LS-QYL application, or BAT46LS-QYL equivalent, key selection criteria include its AEC-Q101 qualification, side-wettable flanks for AOI-compatible solder joint inspection, thermal resistance of 205 K/W on FR4 with 1 cm² cathode pad, and suitability for space-constrained automotive ECUs and infotainment power management.
Technical Context
This Schottky barrier diode leverages a planar epitaxial construction to achieve low forward voltage drop and minimal reverse recovery charge. Its junction temperature rating of 150 °C and ambient operating range from −55 °C to +150 °C support under-hood deployment without derating in standard PCB layouts.
The device operates with no minority-carrier storage, eliminating tail current and enabling clean turn-off in clamping and flyback snubbing circuits. Its 25 pF capacitance at 0 V and 13 pF at 1 V reverse bias ensures minimal signal distortion in high-frequency line termination applications up to 100 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 100 V - supports 48 V automotive systems with 2× safety margin against load dump transients |
| Forward Current (IF) | 250 mA continuous - sufficient for low-power sensor biasing and LED indicator circuits |
| Forward Voltage (VF) | 960 mV at 150 mA - reduces conduction loss by >30% vs. standard silicon diodes in same footprint |
| Reverse Leakage (IR) | 3 µA at 75 V, 25 °C - enables stable voltage clamping in battery-backed real-time clock circuits |
| Diode Capacitance (Cd) | 25 pF at 0 V - preserves signal integrity in USB 2.0 and CAN FD data line termination |
| Reverse Recovery Time (trr) | 3 ns - eliminates switching noise in 1–10 MHz DC-DC converter freewheel paths |
| Thermal Resistance (Rth(j-a)) | 205 K/W on FR4 with 1 cm² cathode pad - allows 610 mW dissipation without heatsink in compact modules |
Pinout & Package
Package: DFN1006BD-2 (SOD882BD), 1.0 mm × 0.6 mm × 0.47 mm body, side-wettable flanks, 0.65 mm pitch, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to higher-potential node in reverse polarity protection; marking bar identifies this terminal |
| 2 | Anode (A) | Connected to lower-potential node (e.g., battery negative or ground); current flows anode→cathode |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including HTOL, TC, and HAST testing per discrete semiconductor stress requirements |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints without X-ray, reducing final test cost in SMT lines |
| Low VF / Low IR trade-off | 960 mV @ 150 mA and 3 µA @ 75 V achieved without compromising junction temperature limit (150 °C) |
| Ultra-small footprint | DFN1006BD-2 occupies 0.6 mm² area-fits within tight spacing constraints of ADAS camera modules and radar sensors |
Applications
| High-Speed Switching | Line Termination |
|---|---|
Use Scenario: Fast-switching buck converter output stage in automotive body control module (BCM). IC Role / Device Role / Timing Role: Freewheeling diode providing low-loss return path during high-side MOSFET off-time.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR0230P2T5G | Lower VR (30 V), higher IF (300 mA), VF = 450 mV @ 100 mA | Restricted to 12 V systems; unsuitable for 48 V or load-dump clamping | Select only when board-level transient suppression is handled elsewhere and space permits larger SOD-923 footprint |
| Vishay VS-2EDH01HM3/85A | Higher VR (200 V), VF = 820 mV @ 200 mA, TO-277 package (3.5 mm × 2.5 mm) | Requires rework of PCB layout; lacks side-wettable flanks for AOI | Choose only if system-level surge immunity exceeds ISO 7637-2 Pulse 5a requirements and manual inspection is acceptable |
Compared with NSR0230P2T5G and VS-2EDH01HM3/85A, BAT46LS-QYL uniquely balances 100 V capability, ultra-small DFN1006BD-2 size, AEC-Q101 compliance, and AOI-ready side-wettable flanks-making it the only option meeting all three criteria for next-gen automotive domain controllers.

FAQ
Is BAT46LS-QYL compatible with lead-free reflow soldering processes?
Yes. BAT46LS-QYL is qualified for reflow soldering only, per manufacturer specification. It supports JEDEC J-STD-020D.1 peak temperatures up to 260 °C with 30-second duration, and requires the SOD882BD footprint shown in Figure 6 of the datasheet for reliable wetting of side-wettable flanks.
What is the maximum allowable PCB copper area for the cathode pad to achieve 610 mW power dissipation?
The 610 mW total power dissipation rating assumes a 1 cm² cathode mounting pad on FR4 with 70 µm single-sided copper and tin plating. Reducing pad area below 1 cm² increases thermal resistance and requires derating-e.g., 0.5 cm² limits safe dissipation to ~420 mW at Tamb = 25 °C.
Does BAT46LS-QYL support bidirectional ESD protection?
No. BAT46LS-QYL is a unidirectional Schottky diode with anode and cathode terminals. For bidirectional ESD protection, a dedicated TVS diode such as PESD5V0S1BA should be used; BAT46LS-QYL functions only as a forward-conducting or reverse-blocking element.
How does the 3 µA reverse leakage at 75 V impact performance in battery backup circuits?
At 3 µA leakage, BAT46LS-QYL draws just 26.3 mAh per year from a 3.3 V RTC backup battery-well within typical coin-cell capacity (e.g., CR2032: 220 mAh). This ensures >8 years of uninterrupted operation without measurable voltage droop in real-time clock hold-up applications.
