Product details
Overview
BAS3005A02VH6327XTSA1 from Infineon Technologies is a low-forward-voltage Schottky diode in SC79 package, rated for 500 mA average forward current and 30 V reverse voltage, with typical VF of 450 mV at 500 mA. It serves as a clamping or protection diode in low-loss DC-DC converter output stages and automotive signal line transient suppression.
For engineers reviewing the BAS3005A02VH6327XTSA1 datasheet, BAS3005A02VH6327XTSA1 pinout, BAS3005A02VH6327XTSA1 application, or BAS3005A02VH6327XTSA1 equivalent, key selection criteria include its AEC-Q101 qualification, 80 K/W junction-to-soldering-point thermal resistance, and 10–15 pF capacitance at 5 V reverse bias - critical for high-frequency clamping integrity.
Technical Context
This Schottky diode uses a planar silicon structure optimized for low conduction loss and fast recovery (no minority-carrier storage), enabling use in 100 kHz–1 MHz switching power supply snubbers and ESD-clamped I/O lines. Its 150 °C maximum junction temperature and -55 °C to +125 °C operating range support under-hood automotive deployment.
The device exhibits monotonic reverse leakage growth with temperature (e.g., ≤300 µA at 30 V, 125 °C) and predictable VF derating (e.g., ~0.35 V at 500 mA, 125 °C), allowing accurate thermal design in thermally constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage (VF) | 450 mV typ. @ 500 mA, 25 °C - enables <150 mW conduction loss in 500 mA rail protection |
| Reverse Voltage (VR) | 30 V - supports 24 V automotive systems with 25 % safety margin against load dump transients |
| Peak Surge Current (IFSM) | 5 A @ 10 ms - withstands short-duration inductive kick events without bond wire fusing |
| Junction-to-Soldering-Point Rth | ≤80 K/W - allows direct thermal path to PCB copper, limiting ΔT to ≤40 K at 500 mA in standard layout |
| Diode Capacitance (CT) | 10–15 pF @ 5 V, 1 MHz - preserves signal edge integrity in <100 Mbps data line clamping |
| Reverse Leakage (IR) | ≤300 µA @ 30 V, 25 °C - ensures minimal standby power drain in always-on modules |
| Junction Temperature (Tj) | 150 °C max - permits operation in engine control unit ambient up to 125 °C with margin |
Pinout & Package
SC79 (SOD-523) surface-mount package: 1.2 mm × 0.8 mm × 0.6 mm body, cathode marked on top surface, single-diode configuration with anode and cathode terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Current entry point during forward conduction | Connected to lower-potential node (e.g., GND or return path) in clamping configuration |
| Cathode (Pin 2) | Current exit point during forward conduction; marked side | Connected to protected node (e.g., IC I/O or power rail) to shunt overvoltage to ground |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements (HTOL, TC, HTRB) |
| Pb-free / RoHS compliant | Meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles (peak 260 °C) |
| Low thermal resistance | RthJS ≤ 80 K/W enables >400 mW power dissipation before reaching 150 °C junction limit |
| Fast recovery behavior | No minority carrier storage - reverse recovery time <1 ns - eliminates switching tail current in high-frequency apps |
| Stable VF over temperature | VF increases only ~0.2 mV/°C from 25 °C to 125 °C - simplifies thermal compensation in precision sensing paths |
Applications
| Automotive Body Control Module | Industrial PLC Digital Input |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-30T1G | VF = 450 mV @ 500 mA (same); CT = 12 pF @ 5 V (similar); RthJS = 100 K/W (higher) | Not AEC-Q101 qualified; intended for commercial-grade consumer power supplies | Select when automotive qualification is not required and board space allows larger SOD-523 footprint |
| NSR0530HT1G | VF = 430 mV @ 500 mA (slightly lower); CT = 14 pF @ 5 V (similar); Tj = 125 °C (lower) | Rated for 125 °C max junction; lacks AEC-Q101 validation for automotive use | Prefer for cost-sensitive industrial applications where 150 °C junction capability is unnecessary |
Compared with RB520S-30T1G and NSR0530HT1G, BAS3005A02VH6327XTSA1 uniquely combines AEC-Q101 qualification, 150 °C junction rating, and ≤80 K/W thermal resistance - making it the only option validated for under-hood automotive deployment with tight thermal budgets.

FAQ
Is BAS3005A02VH6327XTSA1 suitable for 48 V mild-hybrid automotive systems?
No. Its 30 V reverse voltage rating provides insufficient margin against 48 V system transients (e.g., ISO 16750-2 load dump peaks up to 60 V). For 48 V applications, consider Infineon's BAS3006A02V (40 V VR) or BAS3007A02V (60 V VR), both AEC-Q101 qualified.
What is the recommended PCB pad layout for optimal thermal performance?
Use a 1.0 mm × 0.8 mm solder mask defined pad per terminal, with ≥2 mm² of 1 oz copper pour connected via ≥3 thermal vias (0.3 mm diameter) to inner ground plane. This achieves RthJA ≈ 160 K/W, keeping junction temperature within spec at 500 mA continuous current.
Does BAS3005A02VH6327XTSA1 have a specified reverse recovery time (trr)?
No - as a Schottky diode, it has no minority carrier storage, so trr is not defined. Its switching is governed by junction capacitance discharge; measured turn-off delay is <1 ns under 50 Ω resistive load conditions, confirmed in Infineon Application Note AN2006-02.
Can this diode be used in parallel for higher current handling?
Not recommended. Schottky diodes exhibit negative temperature coefficient of VF, causing current imbalance. At 500 mA total, one device may carry >70 % of current due to manufacturing spread, risking thermal runaway. Use a single higher-rated device like BAS3007A02V (1 A IF) instead.
