Product details
Overview
BAS3020BH6327XTSA1 from Infineon Technologies is a single-channel Schottky rectifier diode in SOT363 package, rated for 30 V reverse voltage and 2 A forward current, with typical forward voltage of 530 mV at 2 A and low leakage current of 40 µA at 30 V, used in high-efficiency DC/DC converters and polarity protection circuits.
For engineers reviewing the BAS3020BH6327XTSA1 datasheet, BAS3020BH6327XTSA1 pinout, BAS3020BH6327XTSA1 application, or BAS3020BH6327XTSA1 equivalent, key selection criteria include low VF at high IF, ESD robustness (HBM >8 kV), thermal resistance ≤42 K/W, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Schottky diode employs a planar silicon structure optimized for fast switching and minimal conduction loss. Its low junction capacitance (30 pF at 5 V) and sub-530 mV forward drop at 2 A enable efficient operation in high-frequency buck converters and reverse-polarity protection paths.
The device features integrated ESD protection per HBM Class 3B (>8 kV) and MM Class C (>400 V), plus ISO7637-2 transient immunity (Pulse 1: −100 V/2 ms; Pulse 2: −300 V/50 µs; Pulse 3: −400 V/100 ns), making it suitable for harsh automotive electrical environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - Maximum continuous blocking voltage before breakdown; defines usable input range in 24 V automotive systems. |
| Forward Current (IF) | 2 A - Continuous DC current capability at TS ≤ 96 °C; supports compact power stage designs without forced cooling. |
| Forward Voltage (VF) | 530 mV typ. @ 2 A - Directly reduces conduction loss and heat generation in high-current rectification paths. |
| Junction-to-Solder Thermal Resistance (RthJS) | ≤42 K/W - Enables higher power dissipation in small SOT363 footprint; improves thermal margin over SMA packages. |
| ESD Robustness (HBM) | >8000 V - Eliminates need for external ESD protection in board-level integration for infotainment and body control modules. |
| Capacitance (CT) | 30 pF typ. @ 5 V - Minimizes switching losses and ringing in MHz-range DC/DC controllers. |
| AEC-Q101 Qualified | Yes - Validated for automotive applications including engine control, ADAS power supplies, and lighting drivers. |
Pinout & Package
SOT363 (SC-88) surface-mount package measuring 2.0 × 1.25 × 0.9 mm³, with six terminals in a dual-diode configuration; this part uses only pins 1, 2, and 3 for single-diode operation (anode-cathode-anode), with pins 3 and 4 internally connected to increase current handling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Main anode connection for forward conduction path; routed to input rail in polarity protection. |
| Pin 2 | Cathode | Common cathode output node; connects to load or converter output in clamping/rectification. |
| Pin 3 | Anode (parallel) | Second anode tied internally to Pin 1; enables 2 A rating by doubling bond wire cross-section. |
| Pin 4 | Cathode (parallel) | Second cathode tied internally to Pin 2; lowers effective series resistance and thermal impedance. |
| Pins 5 & 6 | Not connected | No internal connection; left floating or grounded per layout best practices to minimize parasitic coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 530 mV typ. at 2 A - Reduces power loss by >30% vs. standard PN diodes in 12 V–24 V DC/DC stages. |
| High ESD immunity | HBM >8 kV - Survives assembly handling and in-vehicle electrostatic events without derating or shielding. |
| Automotive qualification | AEC-Q101 compliant - Meets stress test requirements for temperature cycling, humidity, and mechanical shock in automotive ECUs. |
| Small footprint | SOT363 (2.0 × 1.25 mm) - Saves >60% PCB area vs. SMA package while maintaining thermal performance via low RthJS. |
| Low leakage current | 40 µA max. @ 30 V - Ensures minimal standby power drain in always-on vehicle subsystems (e.g., CAN wake-up receivers). |
Applications
| Automotive DC/DC Converters | Polarity Protection Circuits |
|---|---|
Use Scenario: Step-down conversion from 12 V battery to 5 V/3.3 V for microcontrollers and sensors in body control modules.

IC Role / Device Role / Timing Role: Bidirectional clamping diode pair (using dual configuration) referenced to VCC and GND rails. Use Value: 30 pF capacitance and >8 kV HBM rating prevent signal distortion while surviving repeated ±8 kV contact discharges. | Use Scenario: High-frequency freewheeling path in boost-type LED drivers for adaptive front lighting systems (AFS). IC Role / Device Role / Timing Role: Freewheeling diode conducting during MOSFET off-time in 500 kHz–1 MHz switching cycles. Use Value: Low CT and fast recovery eliminate tail current, reducing switching loss and enabling stable dimming down to 0.1% duty cycle. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB055LAM-40TR | Lower IF (1.5 A), higher VF (550 mV typ. @ 1.5 A), SOD-123 package (larger footprint) | Lacks AEC-Q101 qualification; not recommended for automotive under-hood use | Select only for cost-sensitive industrial non-automotive DC/DC where space is less constrained. |
| SS32-HF | Higher VR (40 V), same IF (2 A), VF = 500 mV typ. @ 2 A, SMA package (3.5 × 1.6 mm) | Higher thermal resistance (~60 K/W); requires larger copper pour for same power dissipation | Prefer when 40 V VR margin is required (e.g., 36 V systems), but accept 30% larger PCB area and reduced thermal headroom. |
Compared with RB055LAM-40TR and SS32-HF, BAS3020BH6327XTSA1 uniquely combines AEC-Q101 qualification, SOT363 miniaturization, and 42 K/W thermal resistance-enabling high-density automotive power designs where reliability, size, and thermal performance are jointly critical.

FAQ
What is the maximum allowable junction temperature for BAS3020BH6327XTSA1?
The absolute maximum junction temperature (Tj) is 150 °C, validated per AEC-Q101 stress testing. Derating of forward current begins above TA = 25 °C, with full 2 A rating maintained only when solder point temperature (TS) remains ≤96 °C, as confirmed by thermal curves in the official Infineon datasheet.
Can BAS3020BH6327XTSA1 replace SMA-packaged Schottky diodes in existing designs?
Yes-its SOT363 footprint provides direct PCB area reduction versus SMA, but requires verification of thermal performance due to different pad layout and solder thermal mass. The 42 K/W RthJS enables comparable power handling if copper pour and via count match the reference design's thermal profile.
Does BAS3020BH6327XTSA1 support bidirectional ESD protection?
No-it is a unidirectional Schottky rectifier. For bidirectional clamping (e.g., on CAN lines), two devices must be used in series opposition or a dedicated TVS array like ESD56031D05 is required; the device's HBM >8 kV applies only to anode-to-cathode stress direction.
Is lead-free solder reflow compatible with BAS3020BH6327XTSA1's package?
Yes-the SOT363 package is RoHS-compliant and qualified for standard Pb-free reflow profiles (JEDEC J-STD-020, peak 260 °C). The plastic molding compound and termination finish (NiPdAu) withstand multiple reflow cycles without delamination or solder wetting degradation.
