Product details
Overview
BAS52-02V E6327 from Infineon Technologies is a silicon Schottky diode configured as a single medium-current rectifier with 45 V reverse voltage rating, 750 mA forward current capability, and low 420 mV typical forward voltage at 200 mA - used in automotive DC-DC converter output stages for efficient low-loss rectification.
For engineers reviewing the BAS52-02V E6327 datasheet, BAS52-02V E6327 pinout, BAS52-02V E6327 application, or BAS52-02V E6327 equivalent, key selection criteria include its AEC-Q101 qualification, SC79 package thermal resistance (≤60 K/W), junction temperature limit of 150 °C, and ESD-sensitive handling requirements.
Technical Context
This Schottky diode employs a planar silicon structure optimized for fast switching and low conduction loss in medium-power rectification. Its 5 pF typical capacitance at 10 V and 1 MHz supports high-frequency operation up to several hundred kHz in flyback and buck converters.
The device operates across –65 °C to +150 °C storage and junction temperature ranges, with reverse leakage limited to 1 µA at 10 V/25 °C and 80 µA at 10 V/85 °C - enabling stable performance in under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 45 V - supports input-to-output differential in 24 V automotive systems with margin against transients. |
| Forward Current (IF) | 750 mA - enables continuous conduction mode operation in sub-1 W power supplies. |
| Forward Voltage (VF) | 420 mV typ. @ 200 mA - reduces conduction loss by ~30% vs. standard PN diodes in same footprint. |
| Junction Temperature (Tj) | 150 °C - allows operation in engine compartment locations without derating below 125 °C ambient. |
| Thermal Resistance (RthJS) | ≤60 K/W - enables direct PCB copper pour cooling without heatsink in space-constrained modules. |
| Capacitance (CT) | 5 pF @ 10 V, 1 MHz - minimizes switching node ringing in 500 kHz–1 MHz SMPS designs. |
| ESD Rating | Class 3B per JESD22-A114 - requires handling with grounded wrist strap and static-dissipative work surfaces. |
Pinout & Package
SC79 (SOD-523) surface-mount package: 1.2 mm × 0.8 mm × 0.6 mm body, cathode-marked top side, single-diode configuration with anode and cathode terminals only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward bias | Connected to lower-potential node (e.g., switch node in buck topology); must be routed with low-inductance trace. |
| Cathode | Current exit point during forward bias | Connected to output rail; marking dot identifies this terminal - critical for polarity-sensitive PCB layout. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive powertrain and chassis applications per stress test requirements including HTOL, TC, and HAST. |
| Pb-free RoHS-compliant | Meets EU Directive 2011/65/EU with lead content < 0.1 wt%, compatible with lead-free reflow profiles (peak 260 °C). |
| Low VF at high IF | 430 mV max @ 200 mA ensures < 86 mW conduction loss - critical for thermally constrained LED driver PCBs. |
| High IFSM rating | 2000 mA non-repetitive surge withstand enables robustness against inrush and load-dump events in 12 V systems. |
| Small SC79 footprint | 0.96 mm² board area saves >40% space vs. SOD-123 - ideal for multi-rail PMIC output filtering on compact ECUs. |
Applications
| Automotive Body Control Module (BCM) | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Reverse polarity protection on 5 V microcontroller supply rail in door module. IC Role / Device Role / Timing Role: Unidirectional blocking diode preventing damage during battery jump-start misconnection. Use Value: 45 V VR rating accommodates 36 V load-dump spikes; 750 mA IF handles peak MCU + CAN transceiver current. | Use Scenario: Output rectification in isolated 3.3 V DC-DC converter powering analog sensor front-end. IC Role / Device Role / Timing Role: Secondary-side synchronous rectifier replacement in flyback topology. Use Value: 420 mV VF reduces power loss by 120 mW vs. 1N5819, improving efficiency from 78% to 81% at 300 mA load. |

Use Value: 5 pF CT minimizes gate drive coupling noise in adjacent GaN FET control traces. | Use Scenario: ESD protection clamp on analog front-end input channel connected to external probe. IC Role / Device Role / Timing Role: Low-capacitance shunt diode limiting transient overvoltage to ADC input. Use Value: 5 pF CT avoids signal distortion at 100 kHz sensor bandwidth; 150 °C Tj supports sterilization cycle exposure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54LT1G | Same SC79 package, but 30 V VR and 200 mA IF - lower voltage/current rating. | Not suitable for 24 V automotive systems requiring 45 V margin. | Select only for ≤12 V consumer applications where space and cost outweigh voltage headroom needs. |
| BAT54CW | Dual common-cathode Schottky in SOT-323; individual diode rated 30 V/200 mA. | Requires redesign for single-diode function; higher parasitic inductance due to larger package. | Use only when dual-diode functionality is needed or when existing SOT-323 footprint must be retained. |
Compared with SBAT54LT1G and BAT54CW, the BAS52-02V E6327 delivers superior voltage margin and single-diode simplicity for automotive 24 V rectification, while maintaining identical SC79 mounting - eliminating layout change risk in legacy designs.

FAQ
Is BAS52-02V E6327 suitable for reflow soldering with lead-free processes?
Yes. The device is qualified for Pb-free reflow per JEDEC J-STD-020, with peak temperature tolerance up to 260 °C for 30 seconds. Its SC79 package has been validated for standard profile ramp rates (≤3 °C/s) and dwell times without delamination or marking degradation.
What is the maximum allowable PCB copper area for thermal relief with BAS52-02V E6327?
For optimal thermal performance, a minimum 10 mm² exposed copper pad connected to both anode and cathode lands via ≥4 thermal vias (0.3 mm diameter) is recommended. This achieves effective RthJA ≈ 180 K/W, supporting full 750 mA IF at 70 °C ambient.
Does BAS52-02V E6327 require special ESD handling during assembly?
Yes. As an ESD-sensitive Class 3B device, it must be handled using grounded wrist straps, static-dissipative mats, and ionized air blowers. PCB placement should occur in EPA zones with <100 V electrostatic potential; unpopulated reels must remain in shielded packaging until loading.
Can BAS52-02V E6327 replace BAT54 in existing designs?
Only with validation. While both use SC79, BAS52-02V E6327 offers 45 V VR vs. BAT54's 30 V and 750 mA IF vs. 200 mA - enabling higher-voltage operation but requiring check of layout clearance and thermal margin. Forward voltage is comparable (420 mV vs. 450 mV).
