Product details
Overview
BAT32ALSYL from Nexperia is a general-purpose Schottky diode in a DFN1006BD-2 (SOD882BD) leadless SMD package with side-wettable flanks, rated for 30 V reverse voltage and 200 mA forward current, with a typical forward voltage of 480 mV at 200 mA, used for low-loss clamping and rectification in space-constrained DC-DC converters and protection circuits.
For engineers reviewing the BAT32ALSYL datasheet, BAT32ALSYL pinout, BAT32ALSYL application, or BAT32ALSYL equivalent, key selection criteria include ultra-low VF at low IF, AOI-compatible side-wettable flanks, thermal resistance of 205 K/W on optimized PCB layout, and 25 pF junction capacitance at 1 V reverse bias.
Technical Context
This Schottky barrier diode employs a planar silicon structure optimized for fast switching and minimal conduction loss. Its low forward voltage drop stems from a low-barrier-height metal-semiconductor junction, enabling efficient operation in high-frequency, low-voltage power paths.
The device exhibits negligible minority-carrier storage, resulting in near-zero reverse recovery time. Thermal performance is defined by two mounting conditions: standard footprint (Rth(j-a) = 375 K/W) and enhanced cathode pad (Rth(j-a) = 205 K/W), directly impacting maximum continuous power dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - Maximum blocking capability before breakdown; sets upper limit for clamping and input protection applications. |
| Forward Current (IF) | 200 mA - Continuous DC current rating; defines usable load-handling capacity in low-power rectifiers. |
| Forward Voltage (VF) | 480 mV @ 200 mA - Low conduction loss enables >95% efficiency in 3.3 V/5 V DC-DC output stages. |
| Junction Capacitance (Cd) | 25 pF @ 1 V - Enables clean high-speed switching in >10 MHz buck converter freewheeling paths. |
| Reverse Leakage (IR) | 50 µA @ 30 V - Minimal standby power loss critical for battery-powered sensor nodes and always-on circuits. |
| Thermal Resistance (Rth(j-a)) | 205 K/W - Achievable with 1 cm² cathode copper pad; allows 610 mW dissipation at Tamb = 25 °C. |
Pinout & Package
Package: DFN1006BD-2 (SOD882BD), 1.0 mm × 0.6 mm × 0.47 mm body, leadless, side-wettable flanks, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to lower-potential node; marking bar identifies this terminal; carries return current in forward bias. |
| 2 | Anode (A) | Connected to higher-potential node; source of forward current flow; requires proper thermal relief in PCB layout. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small footprint | 1.0 mm × 0.6 mm - Reduces board area by >60% vs. SOD-123, enabling dense power IC integration. |
| Side-wettable flanks | Visible solder fillet on package edges - Enables automated optical inspection (AOI) of solder joint integrity without X-ray. |
| Low forward voltage | 480 mV @ 200 mA - Minimizes I²R losses in 1.8–5 V rail clamping and synchronous rectifier replacement. |
| Pulsed surge capability | IFSM = 3 A @ 8 ms - Withstands inrush and transient overcurrents in USB port protection and hot-swap circuits. |
Applications
| USB Power Delivery Protection | Wearable Device DC-DC Output Rectification |
|---|---|
Use Scenario: Reverse polarity and overvoltage protection on 5–20 V USB PD input rails. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed between input connector and primary regulator. Use Value: 30 V VR withstands PD transient spikes; 480 mV VF limits insertion loss to <25 mW at 50 mA. |
Use Scenario: Freewheeling path in 3.3 V buck converter powering BLE SoC and sensors. IC Role / Device Role / Timing Role: Low-loss synchronous rectifier replacement in high-frequency (2–4 MHz) topology. Use Value: 25 pF Cd ensures minimal switching node ringing; 200 mA IF supports peak load currents. |
| IoT Sensor Node Voltage Clamping | Industrial Control Signal Conditioning |
Use Scenario: ESD and overvoltage clamp on 1.8–3.3 V analog sensor inputs (e.g., temperature, humidity). IC Role / Device Role / Timing Role: Fast-turn-on shunt element limiting input transients to safe levels. Use Value: Near-zero trr prevents signal distortion; 50 µA IR avoids loading high-impedance sensor outputs. |
Use Scenario: Input protection for 24 V digital I/O channels in PLC modules exposed to field wiring noise. IC Role / Device Role / Timing Role: Reverse-biased clamp across optocoupler or logic input to suppress inductive kickback. Use Value: 30 V VR accommodates 24 V nominal + 30% tolerance; side-wettable flanks ensure solder joint reliability in harsh environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ROHM RB520S-40T13 | VF = 370 mV @ 100 mA; VR = 40 V; same DFN1006 package but no side-wettable flanks | Higher reverse voltage margin but lacks AOI support; requires X-ray or manual inspection | Select when higher VR is prioritized over automated assembly verification |
| Vishay VSB1040-H | VF = 450 mV @ 200 mA; VR = 40 V; SOD-923 package (1.0 × 0.6 mm, but 0.35 mm height) | Same footprint area but lower profile; Rth(j-a) = 320 K/W limits power handling | Select when board height is constrained below 0.47 mm and thermal load is <400 mW |
Compared with ROHM RB520S-40T13 and Vishay VSB1040-H, BAT32ALSYL uniquely combines AOI-compatible side-wettable flanks, 30 V/200 mA rating, and 205 K/W thermal resistance on enhanced layout-making it optimal for high-reliability, high-volume consumer and industrial SMT lines where inspection and thermal performance are jointly critical.

FAQ
What is the maximum allowable junction temperature for BAT32ALSYL?
The absolute maximum junction temperature (Tj) is 150 °C per IEC 60134. Operation above this value risks permanent degradation of the Schottky barrier. Derating is required above 25 °C ambient: at 85 °C ambient, maximum continuous IF drops to ~120 mA under standard PCB conditions (Rth(j-a) = 375 K/W).
Does BAT32ALSYL support reflow soldering per JEDEC J-STD-020?
Yes-BAT32ALSYL is qualified for standard lead-free reflow per JEDEC J-STD-020D. Peak temperature must not exceed 260 °C for ≤ 30 seconds. The DFN1006BD-2 package uses a recommended footprint with 0.6 mm pad width and 1.0 mm length per terminal, as specified in Nexperia's SOD882BD layout guide.
Is BAT32ALSYL suitable for automotive applications?
No-BAT32ALSYL is not AEC-Q200 qualified and is explicitly designated for industrial and consumer use. Nexperia states in its legal disclaimers that non-automotive qualified products are unsuitable for safety-critical or life-support systems. Automotive designs require Q200-certified alternatives such as BAT32ALSWX or PNE10030PS.
How does the side-wettable flank design improve manufacturing yield?
Side-wettable flanks allow automated optical inspection (AOI) systems to verify solder fillet formation on the vertical edge of the package, eliminating reliance on X-ray for hidden-joint validation. This reduces inspection cost by ~40% and increases first-pass yield in high-mix SMT lines where rapid defect detection is critical.
