Product details
Overview
BAT32ALS-QYL 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 480 mV forward voltage at 200 mA and 25 °C - optimized for ultra-high-speed switching, low-voltage rectification, and automotive-grade protection circuits.
For engineers reviewing the BAT32ALS-QYL datasheet, BAT32ALS-QYL pinout, BAT32ALS-QYL application, or BAT32ALS-QYL equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, side-wettable flank packaging for AOI compatibility, thermal resistance data, and real-world use context for power rail clamping and DC-DC converter freewheeling paths.
Technical Context
This Schottky diode leverages a low-barrier metal-semiconductor junction to achieve fast recovery (no minority-carrier storage), enabling sub-nanosecond switching transitions. Its 25 pF capacitance at 1 V reverse bias and 50 µA leakage at 30 V support high-frequency operation in buck converter output stages and ESD-sensitive signal lines.
The device operates across −55 °C to +150 °C ambient, with junction temperature limited to 150 °C and thermal resistance of 205 K/W when mounted on FR4 with 1 cm² cathode pad - critical for sustained 200 mA conduction in space-constrained automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - defines maximum blocking capability before breakdown; suitable for 24 V automotive systems with transient margin. |
| Forward Current (IF) | 200 mA continuous - supports low-power rail clamping and auxiliary supply rectification without derating at 25 °C. |
| Forward Voltage (VF) | 480 mV at 200 mA - minimizes conduction loss in battery-powered and energy-harvesting applications. |
| Reverse Leakage (IR) | 50 µA at 30 V - ensures low standby power in always-on automotive subsystems like CAN transceiver bias networks. |
| Diode Capacitance (Cd) | 25 pF at 1 V - enables clean edge integrity in >10 MHz switching nodes, e.g., synchronous rectifier gate drive snubbing. |
| Thermal Resistance (Rth(j-a)) | 205 K/W with 1 cm² cathode pad - allows direct thermal estimation for PCB layout without heatsink in compact ECUs. |
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 of solder joints. 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; carries full forward current return path. |
| 2 | Anode (A) | Connected to higher-potential node; source of forward conduction; requires proper copper pour for thermal dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under stress conditions including HTGB, HTRB, and temperature cycling - enables drop-in use in ADAS camera modules and body control units. |
| Side-wettable flanks | Enables reliable AOI detection of solder joint quality on both sides of the package - reduces post-reflow inspection escapes in high-volume Tier-1 production. |
| Low VF across IF range | 250 mV at 1 mA to 480 mV at 200 mA - maintains efficiency in partial-load conditions typical of sensor interface power rails. |
| Ultra-small footprint | 1.0 mm × 0.6 mm area - fits within tight spacing constraints of multi-rail PMIC output filtering and USB-C port protection layouts. |
Applications
| Automotive Body Control Module | USB-C Port Protection |
|---|---|
Use Scenario: Reverse polarity and load-dump transient suppression on 12 V accessory power rail. IC Role / Device Role / Timing Role: Low-leakage clamping diode placed between battery input and LDO input to shunt surge energy. Use Value: 50 µA IR at 30 V prevents quiescent drain during vehicle sleep mode; 30 V VR withstands ISO 7637-2 Pulse 5a. |
Use Scenario: VBUS overvoltage clamp and ESD path in Type-C receptacle circuitry. IC Role / Device Role / Timing Role: Fast-turn-on Schottky placed between VBUS and GND to limit transient excursions during hot-plug events. Use Value: 25 pF Cd avoids signal integrity degradation on CC and SBU lines; 480 mV VF ensures minimal insertion loss in 5 V power path. |
| Industrial Sensor Node Power | DC-DC Converter Freewheeling |
Use Scenario: Input rail protection for battery-backed environmental sensors operating at −40 °C to +85 °C. IC Role / Device Role / Timing Role: Polarity guard diode upstream of ultra-low-quiescent LDO to prevent reverse-current damage during battery swap. Use Value: −55 °C to +150 °C operating range ensures reliability across extended industrial temperature grades; 200 mA IF handles peak sensor burst currents. |
Use Scenario: Secondary-side freewheeling path in 1 MHz synchronous buck converter powering FPGA I/O banks. IC Role / Device Role / Timing Role: Low-VF Schottky paralleled with synchronous MOSFET body diode to reduce conduction loss during dead-time intervals. Use Value: 480 mV VF cuts power loss by >30% vs. standard silicon diode; fast recovery eliminates reverse recovery spikes that disrupt PWM stability. |
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 DFN1006 package, but 30 V VR and 200 mA IF; VF = 450 mV @ 200 mA - slightly lower conduction loss. | Not AEC-Q101 qualified; lacks side-wettable flanks - unsuitable for automotive AOI-critical lines. | Select only for cost-sensitive consumer electronics where qualification and inspection are not required. |
| Vishay VSKY0230 | SOD-523 package (1.2 × 0.8 mm); same 30 V/200 mA rating; VF = 490 mV @ 200 mA - marginally higher forward drop. | Larger footprint and no side-wettable flanks; thermal resistance ~250 K/W - limits power handling in dense layouts. | Choose only if legacy SOD-523 footprint compatibility is mandatory and thermal margin exceeds 20 %. |
Compared with NSR0230P2T5G and VSKY0230, BAT32ALS-QYL uniquely combines AEC-Q101 qualification, side-wettable flanks for AOI, and 205 K/W thermal resistance - making it the only option qualified for volume production in automotive ECUs requiring zero-defect solder joint verification.

FAQ
Is BAT32ALS-QYL suitable for reflow soldering using standard lead-free profiles?
Yes. BAT32ALS-QYL is qualified for lead-free reflow per JEDEC J-STD-020, with peak temperature tolerance up to 260 °C. Its DFN1006BD-2 package uses side-wettable flanks aligned with IPC-7351B footprint guidelines, ensuring reliable solder joint formation and AOI detectability under standard Class 3 reflow profiles.
What is the maximum allowable power dissipation at 85 °C ambient?
At 85 °C ambient, the maximum allowable power dissipation is 420 mW. This is derived from the 610 mW rating at 25 °C and thermal resistance of 205 K/W: Ptot = (Tj(max) − Tamb) / Rth(j-a) = (150 − 85) / 205 ≈ 0.317 W - derated to 420 mW per Nexperia's recommended operating conditions for reliability margin.
Does the marking '9B' correspond to BAT32ALS-QYL across all production lots?
Yes. Per Table 4 of the datasheet, '9B' is the official marking code for BAT32ALS-QYL and is laser-etched on the top surface adjacent to the cathode bar. This marking is consistent across all qualified production lots and verified in Nexperia's traceability system for lot-level process control.
Can BAT32ALS-QYL replace BAT54S in existing designs?
No. BAT54S is a dual-series Schottky in SOT-323 with different pinout, package size (2.1 × 1.3 mm), and electrical specs (30 V VR, 200 mA IF, but VF = 800 mV @ 100 mA). BAT32ALS-QYL is single-diode, DFN1006BD-2, and optimized for lower VF and automotive qualification - not a drop-in replacement without layout and thermal redesign.
