Product details
Overview
BAS5202VH6327XTSA1 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 12 V system rectification.
For engineers reviewing the BAS5202VH6327XTSA1 datasheet, BAS5202VH6327XTSA1 pinout, BAS5202VH6327XTSA1 application, or BAS5202VH6327XTSA1 equivalent, key selection criteria include AEC-Q101 qualification, thermal resistance ≤60 K/W, junction temperature up to 150 °C, and SC79 package compatibility with high-density automotive PCB layouts.
Technical Context
This Schottky diode employs a planar silicon structure optimized for low VF and fast switching, with no minority-carrier storage delay. Its 5 pF capacitance at 10 V reverse bias and <10 µA leakage at 45 V support high-frequency rectification in buck converters.
The device operates across –65 °C to +150 °C ambient, with derated forward current down to 300 mA at 120 °C case temperature. Thermal resistance from junction to soldering point is specified ≤60 K/W, enabling direct thermal modeling in compact power modules.
Key Specifications

|---|---|
| Reverse Voltage (VR) | 45 V - supports 36 V automotive transients without breakdown |
| Forward Current (IF) | 750 mA - continuous conduction capability for mid-power DC-DC outputs |
| Forward Voltage (VF) | 420 mV typ. @ 200 mA - reduces conduction loss by ~30% vs. standard PN diodes |
| Junction Temp (Tj) | 150 °C - enables operation in under-hood environments with minimal derating |
| Thermal Resistance (RthJS) | ≤60 K/W - allows accurate junction temperature prediction from solder-point measurement |
| Capacitance (CT) | 5 pF @ 10 V, 1 MHz - minimizes switching loss and EMI in >100 kHz converters |
| ESD Rating | AEC-Q101 qualified - withstands human-body-model discharges ≥2 kV per JEDEC JESD22-A114 |
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 node | Connected to switch node in synchronous buck topology; must handle pulsed IFSM = 2 A |
| Cathode | Current exit node | Connected to output rail; marking visible on top surface for automated optical inspection |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 420 mV typ. @ 200 mA - directly lowers power loss and heatsink requirements |

| Pb-free RoHS compliance | Meets EU Directive 2011/65/EU - supports lead-free reflow profiles up to 260 °C peak |
| High surge current tolerance | 2000 mA non-repetitive peak - handles inrush and fault currents in 12 V systems |
| Small-footprint SC79 | 1.2 × 0.8 mm footprint - saves >60% board area vs. SOD-123 in space-constrained ECUs |
Applications
| Automotive Body Control Module (BCM) | Infotainment Power Supply |
|---|---|
Use Scenario: Rectifying switched 12 V input in BCM sub-regulators powering window lifters and mirror controls. IC Role / Device Role / Timing Role: Output rectifier in 300 kHz buck converter supplying 5 V/1.2 A to microcontroller and CAN transceivers. Use Value: 420 mV VF reduces power dissipation by 180 mW vs. BAS21, improving thermal margin in sealed enclosures. | Use Scenario: Secondary-side rectification in USB-C PD adapter auxiliary supply for display backlight drivers. IC Role / Device Role / Timing Role: Fast-recovery rectifier in 500 kHz flyback snubberless design delivering 3.3 V/800 mA. Use Value: 5 pF CT limits capacitive coupling noise into sensitive audio amplifiers, reducing post-regulation filtering needs. |
| Engine Control Unit (ECU) Sensor Bias | ADAS Camera Module Power |
Use Scenario: Reverse-polarity protection and ESD clamping for 5 V sensor reference rails in engine bay. IC Role / Device Role / Timing Role: Bidirectional clamp diode placed between VREF and GND, leveraging low IR and AEC-Q101 robustness.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-40T1G | 40 V VR, 200 mA IF, SOD-523 package, VF = 370 mV @ 100 mA | Limited to low-power logic rails; insufficient for 500 mA automotive loads | Select when lower VF and cost priority outweigh voltage margin needs |
| NSR0230HT1G | 30 V VR, 200 mA IF, SOD-523, VF = 360 mV @ 100 mA, no AEC-Q101 | Not qualified for automotive use; unsuitable for under-hood deployment | Acceptable only for consumer-grade portable devices with <85 °C ambient |
Compared with BAS5202VH6327XTSA1, RB520S-40T1G trades 5 V VR headroom for slightly lower VF but cannot sustain 750 mA, while NSR0230HT1G lacks automotive qualification and voltage rating - making BAS5202VH6327XTSA1 the sole option meeting AEC-Q101, 45 V, and 750 mA simultaneously.

FAQ
Is BAS5202VH6327XTSA1 suitable for synchronous rectification?
No - it is a unidirectional Schottky rectifier, not a MOSFET-based synchronous rectifier controller or driver. It functions as a passive rectifying element and requires external switching control. Its 420 mV VF and 5 pF CT make it appropriate for freewheeling or output rectification in non-synchronous topologies up to 500 kHz.
What is the maximum allowable PCB pad temperature during reflow?
The SC79 package is rated for lead-free reflow with peak temperature up to 260 °C for ≤10 seconds, per IPC/JEDEC J-STD-020. The device's internal junction temperature limit remains 150 °C, so thermal design must ensure solder-point temperature does not cause sustained Tj > 150 °C during operation.
Does this diode require a heatsink in 750 mA continuous operation?
No external heatsink is required if PCB copper area provides ≤60 K/W total thermal resistance from junction to ambient. With RthJS ≤60 K/W and typical RthSA ≈ 120 K/W on 1 cm² 1-oz copper, junction temperature stays below 150 °C at 750 mA and 25 °C ambient - verified via thermal simulation using provided RthJS and VF data.
Can BAS5202VH6327XTSA1 replace BAS21 in existing designs?
Only with circuit review: BAS5202VH6327XTSA1 has higher VR (45 V vs. 250 V), lower VF (420 mV vs. 1.25 V), but lower IF (750 mA vs. 200 mA). It improves efficiency in low-voltage, moderate-current applications but cannot substitute in high-voltage line rectification. Layout change is needed due to SC79 vs. SOD-123 footprint.
