Product details
Overview
BAT32LS from Nexperia is a general-purpose Schottky diode in a DFN1006BD-2 (SOD882BD) ultra-small leadless package, rated for 30 V reverse voltage and 200 mA forward current, with 600 mV forward voltage at 200 mA and 2 µA reverse leakage at 30 V, used in low-power rectification and voltage clamping circuits.
For engineers reviewing the BAT32LS datasheet, BAT32LS pinout, BAT32LS application, or BAT32LS equivalent, this device is selected for space-constrained, high-efficiency DC-DC converter output stages, ESD-sensitive signal line protection, and battery-powered IoT node power management where low VF and side-wettable flanks for AOI are critical.
Technical Context
The BAT32LS employs a planar Schottky barrier structure optimized for low forward voltage drop and fast switching recovery, enabling sub-10 ns reverse recovery times without minority carrier storage. Its thermal design supports operation up to 150 °C junction temperature with Rth(j-a) of 205 K/W on a 1 cm² cathode pad.
Designed for reflow-soldered SMD assembly, it features side-wettable flanks per JEDEC J-STD-020, allowing automated optical inspection of solder joints. The cathode-marking bar and symmetric 0.65 mm pitch simplify PCB layout and automated placement in high-density designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - Maximum blocking capability before breakdown; suitable for 24 V rail clamping and 5 V/3.3 V system protection. |
| Forward Current (IF) | 200 mA continuous - Supports low-power supply rails and signal-level rectification without derating at 25 °C ambient. |
| Forward Voltage (VF) | 600 mV at 200 mA - Minimizes conduction loss in battery-fed devices; enables >95% efficiency in 1.8 V–3.3 V buck converter freewheel paths. |
| Reverse Leakage (IR) | 2 µA at 30 V - Ensures minimal standby current drain in always-on sensor nodes and real-time clock backup circuits. |
| Diode Capacitance (Cd) | 20 pF at 1 V - Low capacitance preserves signal integrity in high-frequency clamp applications up to ~100 MHz. |
| Package | DFN1006BD-2 (SOD882BD), 1.0 × 0.6 × 0.47 mm - Enables <0.6 mm² board area usage; compatible with 0201 footprint automation. |
Pinout & Package
DFN1006BD-2 is a 2-terminal leadless plastic package with side-wettable flanks, 0.65 mm pitch, and cathode marked by a visible bar on the top surface. Thermal performance is optimized with dedicated cathode-side copper pad (1 cm² recommended).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to lower-potential node; marking bar identifies this terminal; primary heat path to PCB via exposed cathode pad. |
| 2 | Anode (A) | Connected to higher-potential node; carries forward current into load; no thermal pad connection. |
Key Features
| Feature | Design Value |
|---|---|
| Side-wettable flanks | Enables 100% automated optical inspection (AOI) of solder fillets without X-ray, reducing post-reflow defect escapes in high-volume manufacturing. |
| Ultra-low forward voltage | 600 mV at full rated current reduces power loss by ≥40% versus standard silicon diodes in 3.3 V systems, extending battery life in wearables. |
| Low reverse leakage | 2 µA at 30 V ensures <1 µW standby dissipation in always-on protection circuits, critical for coin-cell-powered sensors. |
| Small outline footprint | 1.0 mm × 0.6 mm body size allows placement in tight spaces between BGA balls or under connectors, improving PCB routing density. |
Applications
| USB Data Line Protection | DC-DC Converter Freewheel Diode |

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 | Same 30 V/200 mA rating but 450 mV VF at 200 mA; larger SOD-923 (1.0 × 0.6 × 0.4 mm) package with no side-wettable flanks. | Lacks AOI support; requires X-ray for solder joint verification; better for cost-sensitive non-AOI production. | Select when lowest possible VF is prioritized over manufacturability and footprint size is not constrained. |
| Vishay VS-2EDL02LMTR-M3 | Higher 2 A IFSM, but 35 V VR and 750 mV VF; SOD-123FL package (3.7 × 1.6 × 1.1 mm) - 10× larger footprint. | Suitable for surge-heavy industrial inputs; unsuitable for space-limited consumer PCBs. | Select only when peak surge immunity >3 A is required and board area permits larger package. |
Compared with NSR0230P2T5G and VS-2EDL02LMTR-M3, BAT32LS uniquely balances ultra-small size, AOI compatibility, and mid-range VF/IR trade-off-making it optimal for high-volume, miniaturized consumer electronics where process yield and board density are co-critical.

FAQ
Is BAT32LS suitable for reflow soldering with standard lead-free profiles?
Yes. BAT32LS is qualified for JEDEC J-STD-020 Class 3 moisture sensitivity level and supports peak reflow temperatures up to 260 °C. Its side-wettable flanks are specifically designed for visual AOI after standard Pb-free reflow, and the DFN1006BD-2 footprint matches IPC-7351B recommendations.
What is the maximum allowable junction temperature during continuous operation?
The absolute maximum junction temperature is 150 °C. Under continuous 200 mA forward current at 25 °C ambient, junction temperature rise is approximately 41 °C (using Rth(j-a) = 205 K/W on 1 cm² cathode pad), resulting in Tj ≈ 66 °C - well within safe operating range.
Does the cathode marking bar indicate polarity during automated optical inspection?
Yes. The laser-marked bar on the top surface unambiguously identifies Pin 1 as cathode, enabling AOI systems to verify correct orientation and solder wetting on both side-wettable flanks. This eliminates manual polarity checks and reduces misplacement defects in high-speed pick-and-place lines.
Can BAT32LS replace BAT54 series diodes in existing designs?
No direct replacement: BAT54 uses SOT-23 package (3.0 × 1.4 × 1.1 mm) with different pinout and thermal behavior. While electrical ratings overlap, the BAT32LS's DFN1006BD-2 footprint requires PCB redesign. It is not a drop-in substitute but a next-generation alternative for new ultra-compact layouts.
