Product details
Overview
BAS52-02V E6433 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 - optimized for automotive power rail clamping and signal-level DC-DC converter freewheeling in engine control units.
For engineers reviewing the BAS52-02V E6433 datasheet, BAS52-02V E6433 pinout, BAS52-02V E6433 application, or BAS52-02V E6433 equivalent, key selection criteria include its AEC-Q101 qualification, SC79 package thermal resistance (≤60 K/W), 5 pF junction capacitance at 10 V, and guaranteed 1 µA max reverse leakage at 10 V/85°C.
Technical Context
This Schottky diode employs a planar silicon epitaxial structure to achieve low forward voltage drop without compromising reverse blocking integrity. Its 45 V VR rating supports 24 V automotive systems with margin, while the 2000 A non-repetitive surge rating enables robust transient handling during load dump events.
The device operates across –65 °C to +150 °C junction temperature range and meets AEC-Q101 stress test requirements for high-reliability automotive use. Thermal resistance from junction to soldering point is ≤60 K/W, enabling direct PCB copper pour heatsinking in compact layouts.
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 sufficient for low-power DC-DC output rectification in body electronics modules. |
| Forward Voltage (VF) | 420 mV typ. @ 200 mA - reduces conduction loss by >30% vs. standard PN diodes, critical for thermally constrained ECUs. |
| Junction Capacitance (CT) | 5 pF @ 10 V, 1 MHz - enables fast switching in 1–10 MHz buck converter freewheel paths without excessive ringing. |
| Reverse Leakage (IR) | 1 µA max @ 10 V, 85°C - ensures minimal standby current drain in always-on vehicle networks (e.g., CAN wake-up circuits). |
| Thermal Resistance (RthJS) | ≤60 K/W - allows 0.5 W dissipation with <30 K rise above solder point, compatible with 2-layer FR4 PCBs without thermal vias. |
Pinout & Package
Package: SC79 - ultra-small surface-mount plastic package (1.35 mm × 0.8 mm × 0.55 mm), cathode-marked, RoHS-compliant, designed for high-density automotive PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Current entry terminal | Connected to switched input (e.g., buck converter switch node) to enable forward conduction path. |
| Cathode (Pin 2) | Current exit terminal | Connected to output rail or ground return; marking stripe identifies this terminal on PCB silkscreen. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood environments including temperature cycling, humidity bias, and mechanical shock per Rev G. |
| Low VF at high IF | 430 mV max @ 200 mA ensures <100 mW conduction loss in 5 V/300 mA auxiliary supplies. |
| ESD-sensitive handling | Class H2 (≥2 kV HBM) - requires grounded workstations and static-dissipative packaging during SMT placement. |
| Pb-free & RoHS compliant | Meets EU Directive 2011/65/EU and JESD204B; no lead content in die attach or termination plating. |
Applications
| Engine Control Unit (ECU) Power Clamp | Body Control Module (BCM) DC-DC Freewheel |
|---|---|
Use Scenario: Clamps inductive kickback from fuel injector drivers during turn-off in 12 V/24 V engine management systems. IC Role / Device Role / Timing Role: Fast-recovery freewheel diode providing sub-10 ns turn-on to limit voltage overshoot below 45 V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSSR0230MXV6T1G | 30 V VR, 200 mA IF, 380 mV VF @ 100 mA - lower voltage rating but tighter VF tolerance. | Not suitable for 24 V systems requiring >40 V blocking; limited to 5 V/3.3 V logic rails. | Select only for low-voltage consumer-grade modules where AEC-Q101 is not required. |
| Vishay VS-2EDH02HM3/85A | 45 V VR, 2 A IF, TO-236AB package - higher current, larger footprint, RthJA = 120 K/W. | Requires 3× PCB area and thermal relief; over-specified for space-constrained ECUs. | Prefer when surge current >1500 A is needed or reworkability with hand soldering is mandatory. |
Compared with NSSR0230MXV6T1G and VS-2EDH02HM3/85A, the BAS52-02V E6433 uniquely balances AEC-Q101 compliance, SC79 miniaturization, and 45 V/750 mA capability - making it the only choice for production 24 V automotive modules where board area and qualification are co-constrained.

FAQ
Is BAS52-02V E6433 pin-compatible with BAS52-02W or BAS52-02X?
No. BAS52-02V uses SC79 package with anode-cathode orientation matching Infineon's standard marking layout; BAS52-02W is SC70 with reversed pinout, and BAS52-02X is SOD-523 with different thermal pad geometry. Mechanical and electrical mounting are not interchangeable.
What is the maximum allowable soldering temperature profile for BAS52-02V E6433?
The SC79 package supports standard lead-free reflow per IPC/JEDEC J-STD-020D: peak temperature 260°C for ≤10 seconds, with ramp-up rate ≤3°C/s and ramp-down rate ≤6°C/s. Preheat to 150°C for 90–120 s before soak.
Does BAS52-02V E6433 require external heat sinking in 750 mA continuous operation?
No. With RthJS ≤60 K/W and Ptot = 500 mW, dissipation at 750 mA (VF ≈ 480 mV) yields ~360 mW loss - resulting in ≤22 K junction-to-solder-point rise on a 2-layer PCB with 10 mm² copper pour, well within Tj = 150°C limit.
Can BAS52-02V E6433 be used in AC signal detection applications?
Yes - its 5 pF CT and <100 ps reverse recovery time support RF envelope detection up to 200 MHz, but forward voltage variation with temperature (–1.2 mV/°C) limits precision DC-coupled measurement accuracy beyond ±2°C ambient stability.
