Product details
Overview
BAS5202VH6433XTMA1 from Infineon Technologies is a silicon Schottky diode configured as a single medium-current rectifier, featuring 45 V reverse voltage rating, 750 mA forward current capability, and low 420 mV forward voltage at 200 mA - optimized for automotive power rail clamping and DC-DC converter output rectification.
For engineers reviewing the BAS5202VH6433XTMA1 datasheet, BAS5202VH6433XTMA1 pinout, BAS5202VH6433XTMA1 application, or BAS5202VH6433XTMA1 equivalent, key selection criteria include AEC-Q101 qualification, SC79 package thermal resistance (≤60 K/W), junction temperature limit (150 °C), and low IR (<1 µA at VR = 10 V, TA = 85 °C).
Technical Context
This Schottky diode employs a planar silicon process with metal–semiconductor junction to achieve fast switching (no minority-carrier storage) and low VF across operating temperatures. Its 45 V VR rating supports 24 V automotive systems with margin, while the 2000 A non-repetitive surge rating enables robust transient handling in load-dump scenarios.
The device is qualified per AEC-Q101 Rev D for stress testing including HTGB, HTRB, and TCT, and features RoHS-compliant Pb-free packaging. Thermal design relies on RthJS ≤ 60 K/W to soldering point, enabling operation up to TS = 110 °C with 500 mW total power dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 45 V - supports 24 V nominal automotive rails with ≥87% derating margin against ISO 7637-2 pulse 5a (35 V peak). |
| Forward Current (IF) | 750 mA - continuous conduction capability suitable for auxiliary power supply rectification in body control modules. |
| Forward Voltage (VF) | 420 mV @ 200 mA - reduces conduction loss by ~35% vs. standard PN diodes, lowering thermal load in compact PCB layouts. |
| Reverse Current (IR) | 1 µA @ VR = 10 V, TA = 85 °C - ensures minimal leakage in always-on battery monitoring circuits. |
| Junction Temperature (Tj) | 150 °C - enables reliable operation in under-hood environments with ambient up to 125 °C and self-heating. |
| Thermal Resistance (RthJS) | ≤60 K/W - allows direct thermal path to copper pour or heatsink pad, supporting >500 mW dissipation at TS = 110 °C. |
Pinout & Package
Package: SC79 (SOD-523), surface-mount, single-diode configuration with cathode marked by bar on top surface. Dimensions: 1.2 mm × 0.8 mm × 0.66 mm (L × W × H), 0.55 mm pitch, 0.2 mm thickness.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Current entry point during forward bias | Connected to lower-potential node (e.g., switch-node of buck converter); requires low-inductance trace routing. |
| Cathode (Pin 2) | Current exit point during forward bias; marked with bar | Connected to output rail or ground return; serves as reference for clamping and ESD protection paths. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS power supplies. |
| Low VF at high IF | 420 mV @ 200 mA enables >92% efficiency in 5 V/3 A buck output stage at full load. |
| Pb-free RoHS package | SC79 outline meets JEDEC MO-203-AB, compatible with lead-free reflow profiles (peak 260 °C). |
| High IFSM rating | 2000 A surge capacity withstands ISO 16750-2 load dump transients without degradation. |
Applications
| Automotive Body Control Module | Industrial DC-DC Converter |
|---|---|
Use Scenario: Reverse polarity protection and flyback energy recirculation in 12 V/24 V BCM power inputs. IC Role / Device Role / Timing Role: Schottky rectifier providing low-loss freewheeling path for relay coils and motor drivers. Use Value: 420 mV VF minimizes heat generation in confined enclosures; AEC-Q101 ensures 15-year field reliability. | Use Scenario: Output rectification in isolated 48 V-to-12 V flyback converters for factory automation I/O modules. IC Role / Device Role / Timing Role: Secondary-side synchronous rectifier replacement, reducing conduction loss versus MOSFET gate drive complexity. Use Value: 750 mA IF and 45 V VR cover full load range; SC79 footprint saves board space vs. SOD-123. |
| Automotive Infotainment Power Supply | LED Driver Clamping Circuit |
Use Scenario: Input overvoltage clamping and ESD protection for USB-C PD input stages in head unit power management ICs. IC Role / Device Role / Timing Role: Transient voltage suppressor and DC blocking diode in dual-role power path. Use Value: 1 µA IR at 85 °C prevents standby current drain; 150 °C Tj supports operation near SoC thermal zones. | Use Scenario: Reverse-biased clamp across LED strings to absorb inductive kickback from constant-current driver switches. IC Role / Device Role / Timing Role: Fast-recovery freewheeling diode limiting voltage overshoot during PWM off-time. Use Value: 5 pF CT at 10 V enables <1 ns turn-off delay; 2000 A IFSM handles repetitive inductive spikes. |
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, 370 mV VF @ 100 mA - lower voltage rating and current, smaller SOD-523 footprint. | Not AEC-Q101 qualified; limited to consumer-grade portable electronics. | Select only for cost-sensitive non-automotive designs where 40 V margin suffices. |
| NSR0240HT1G | 40 V VR, 200 mA IF, 450 mV VF @ 200 mA - same package, no AEC-Q101, higher VF than BAS5202VH6433XTMA1. | Lacks automotive qualification and thermal derating data for under-hood use. | Acceptable for industrial sensors with <85 °C ambient, but not for BCM or infotainment. |
Compared with RB520S-40T1G and NSR0240HT1G, BAS5202VH6433XTMA1 delivers higher VR (45 V), higher IF (750 mA), AEC-Q101 compliance, and lower VF at rated current - making it the sole choice for thermally constrained, safety-critical automotive power rectification.

FAQ
Is BAS5202VH6433XTMA1 suitable for synchronous rectification in DC-DC converters?
No - this is a passive Schottky diode, not a synchronous rectifier IC or MOSFET driver. It functions as a freewheeling or output rectifier in non-synchronous topologies like flyback or buck. For synchronous rectification, an active gate driver paired with a low-RDS(on) MOSFET is required.
What is the maximum allowable soldering temperature profile for BAS5202VH6433XTMA1?
The SC79 package is qualified for lead-free reflow per JEDEC J-STD-020, with peak temperature of 260 °C for ≤30 seconds. Preheat ramp rate must not exceed 3 °C/s, and time above 217 °C must be 60–150 seconds. No wave soldering is recommended due to thermal stress on the small-body package.
Does BAS5202VH6433XTMA1 have integrated ESD protection?
No - it is an ESD-sensitive device (Class 1C per ANSI/ESDA/JEDEC JS-001), requiring handling per electrostatic discharge precautions. It does not contain internal ESD protection structures; external TVS diodes or layout-level guarding must be used in system-level ESD protection schemes.
Can BAS5202VH6433XTMA1 replace BAS5202VH6327XTMA1 in existing designs?
Yes - both share identical electrical specs, AEC-Q101 qualification, SC79 package, and marking layout. The "6433" and "6327" suffixes denote different reel packaging (3,000 vs. 10,000 pieces per reel) and date code formats; no functional or reliability differences exist between them.
