Product details
Overview
BAT32LS-Q from Nexperia is a general-purpose Schottky diode in DFN1006BD-2 (SOD882BD) 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 for ultra-high-speed switching and voltage clamping in automotive power rails.
For engineers reviewing the BAT32LS-Q datasheet, BAT32LS-Q pinout, BAT32LS-Q application, or BAT32LS-Q equivalent, key selection criteria include low VF for efficiency-critical 3.3 V/5 V rail protection, AEC-Q101 qualification for under-hood use, side-wettable flanks for AOI-compatible solder joint inspection, and thermal resistance of 205 K/W on optimized PCB layout.
Technical Context
This Schottky diode leverages a low-barrier metal-semiconductor junction to achieve fast recovery (<1 ns), minimal stored charge, and no minority-carrier tail current-enabling clean switching in DC-DC converter freewheeling paths and reverse-polarity protection circuits. Its 20 pF capacitance at 1 V reverse bias supports high-frequency operation up to 100 MHz.
The device operates across −55 °C to +150 °C junction temperature, with thermal resistance dependent on PCB copper area: 375 K/W on standard footprint vs. 205 K/W with 1 cm² cathode pad. Reverse leakage remains ≤2 µA at 25 °C and 30 V, rising predictably with temperature per Fig. 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - Maximum blocking capability for 24 V automotive systems with transient margin. |
| Forward Current (IF) | 200 mA continuous - Supports low-power signal path clamping and auxiliary rail rectification. |
| Forward Voltage (VF) | 600 mV at 200 mA - Minimizes conduction loss in battery backup and OR-ing circuits. |
| Reverse Leakage (IR) | 2 µA at 30 V, 25 °C - Ensures low standby power in always-on automotive modules. |
| Diode Capacitance (Cd) | 20 pF at 1 V, 1 MHz - Enables stable operation in RF-coupled ESD protection networks. |
| Thermal Resistance (Rth(j-a)) | 205 K/W with 1 cm² cathode pad - Allows 610 mW power dissipation in thermally enhanced layouts. |
| Junction Temperature (Tj) | 150 °C max - Rated for under-dash and engine bay locations per AEC-Q101 stress testing. |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a 2-terminal, leadless surface-mount package measuring 1.0 mm × 0.6 mm × 0.47 mm with side-wettable flanks for automated optical inspection. The cathode is marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to lower-potential node; marking bar identifies this terminal for polarity-sensitive placement. |
| 2 | Anode (A) | Connected to higher-potential node; current flows from Pin 2 to Pin 1 during forward conduction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and body electronics. |
| Side-wettable flanks | Enables reliable automated optical inspection (AOI) of solder joints without X-ray. |
| Low forward voltage | 600 mV at full rated current reduces power loss in battery-powered and energy-sensitive designs. |
| Ultra-small footprint | 1.0 mm × 0.6 mm area saves board space in compact modules like ADAS sensors and infotainment ECUs. |
| Low reverse leakage | 2 µA at 30 V ensures minimal quiescent current drain in always-on vehicle networks (e.g., CAN FD wake-up lines). |
Applications
| Automotive Reverse-Polarity Protection | USB Power Path OR-ing |
|---|---|
Use Scenario: Prevents damage when battery terminals are connected backward in 12 V/24 V vehicle subsystems. IC Role / Device Role / Timing Role: Low-VF Schottky diode placed in series with power input to block reverse current flow. Use Value: 600 mV VF limits voltage drop to <2% at 200 mA, preserving regulator headroom while meeting AEC-Q101 reliability requirements. |
Use Scenario: Selects between main USB port and external power adapter in portable diagnostic tools. IC Role / Device Role / Timing Role: Discrete OR-ing diode enabling seamless source switchover without microcontroller intervention. Use Value: 200 mA rating and 20 pF capacitance prevent data-line coupling noise during hot-plug events on USB 2.0 interfaces. |
| Low-Voltage Rectification | ESD-Clamp Auxiliary Diode |
Use Scenario: Converts low-amplitude AC signals from Hall-effect sensors into unidirectional pulses. IC Role / Device Role / Timing Role: Signal-level rectifier in analog front-end stages of motor position feedback circuits. Use Value: Sub-300 mV VF at 1 mA enables accurate detection of weak sensor outputs down to 100 mV amplitude. |
Use Scenario: Augments TVS diode arrays in LIN bus transceiver I/O protection networks. IC Role / Device Role / Timing Role: Fast-turn-on clamp that conducts before TVS breakdown to limit transient overshoot. Use Value: <1 ns recovery time and 2 µA leakage ensure no interference with 20 kbps LIN signaling integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB521S-30T2R | Same 30 V VR, but 200 mA IF and 370 mV VF at 10 mA; SOD-523 package (1.2 × 0.8 mm). | Larger footprint and higher VF at low current reduce efficiency in micro-power sensor nodes. | Select when legacy SOD-523 footprint compatibility is required over AOI support. |
| NSR0230P2T5G | 30 V VR, 200 mA IF, 450 mV VF at 100 mA; SOD-923 package (1.0 × 0.6 mm) without side-wettable flanks. | Lacks AEC-Q101 qualification and AOI capability, limiting use to non-automotive consumer designs. | Choose for cost-sensitive industrial IoT where automotive qualification is unnecessary. |
Compared with RB521S-30T2R and NSR0230P2T5G, BAT32LS-Q uniquely combines AEC-Q101 qualification, side-wettable flanks for AOI, and 600 mV VF at full 200 mA load-making it optimal for space-constrained, safety-aware automotive power management.

FAQ
Is BAT32LS-Q suitable for reflow soldering?
Yes, BAT32LS-Q is qualified for standard lead-free reflow soldering per J-STD-020. Its DFN1006BD-2 package uses side-wettable flanks compatible with IPC-A-610 Class 2/3 visual inspection, and the recommended footprint (Fig. 5) specifies 0.6 mm solder lands with 0.7 mm spacing for reliable joint formation.
What is the meaning of the '8X' marking on BAT32LS-Q?
The '8X' marking on the top surface identifies the BAT32LS-Q device per Nexperia's ordering table. It appears adjacent to the cathode bar and serves as the traceable part identifier for assembly verification and counterfeit prevention in automotive supply chains.
How does thermal performance change with PCB layout?
Rth(j-a) drops from 375 K/W (standard FR4 footprint) to 205 K/W when a 1 cm² tin-plated copper pad is used under the cathode terminal. This 45% improvement allows 610 mW power dissipation versus 335 mW-critical for sustained 200 mA operation in enclosed automotive enclosures.
Can BAT32LS-Q replace BAT54S in existing designs?
No-BAT54S is a dual-series Schottky in SOT-323 with different pinout, 30 V rating, and 200 mA per diode, but lacks AEC-Q101 qualification and side-wettable flanks. BAT32LS-Q is single-diode only and requires PCB redesign; it is not a drop-in replacement despite shared voltage/current ratings.
