Product details
Overview
BAS5202VE6127XT 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, 420 mV typical forward voltage at 200 mA, and SC79 surface-mount package - used in automotive DC-DC converter output rectification per AEC-Q101 qualification.
For engineers reviewing the BAS5202VE6127XT datasheet, BAS5202VE6127XT pinout, BAS5202VE6127XT application, or BAS5202VE6127XT equivalent, key selection criteria include low VF at high IF, thermal resistance ≤60 K/W, AEC-Q101 qualification, RoHS-compliant Pb-free packaging, and junction temperature up to 150°C for under-hood power conversion designs.
Technical Context
This Schottky diode employs a planar silicon structure optimized for fast switching and low conduction loss in medium-power rectification. Its 45 V VR rating supports 24 V automotive systems with margin, while the 750 mA IF rating enables continuous operation in compact buck converter outputs without forced cooling.
Thermal design is supported by RthJS ≤60 K/W (junction-to-soldering point), enabling reliable operation at TS ≤110°C. The device exhibits IR ≤1 µA at VR = 10 V and TA = 25°C, and CT = 5–10 pF at VR = 10 V / f = 1 MHz - critical for EMI-sensitive power supply filtering stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 45 V - supports 24 V nominal automotive bus with 88% derating margin against transients |
| Forward Current (IF) | 750 mA - enables continuous conduction mode operation in sub-1 W DC-DC converters |
| Forward Voltage (VF) | 420 mV typ. @ 200 mA - reduces conduction loss by ~35% vs. standard PN diodes in same footprint |
| Junction Temp (Tj) | 150 °C - allows placement near hot components in engine control units without thermal shutdown |
| Thermal Resistance (RthJS) | ≤60 K/W - permits direct PCB copper pour heatsinking without thermal vias in space-constrained layouts |
| Capacitance (CT) | 5–10 pF @ 10 V / 1 MHz - minimizes high-frequency ringing in synchronous rectifier snubber networks |
Pinout & Package
SC79 package: ultra-small surface-mount outline (1.35 × 0.8 × 0.35 mm), cathode-marked single-diode configuration, designed for high-density automotive PCBs with 2 mm tape pitch reel delivery.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Current entry node | Connected to switch-node side of buck converter; requires low-inductance trace routing |
| Cathode (Pin 2) | Current exit node | Connected to output capacitor ground return; marked with cathode bar on top surface |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive power electronics per stress test requirements (HTOL, TC, HAST) |
| Pb-free RoHS package | Complies with EU Directive 2011/65/EU; compatible with lead-free reflow profiles (peak 260°C) |
| Low VF at high IF | 420 mV @ 200 mA ensures <100 mW conduction loss in 5 V/0.5 A output stage |
| ESD sensitivity class | HBM Class 2 (2 kV) - requires static-safe handling during SMT assembly and board test |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54LT1G | 40 V VR, 200 mA IF, SOT-23 package, VF = 450 mV @ 100 mA | Lower current rating; unsuitable for >300 mA continuous loads | Select only for space-constrained non-automotive consumer applications with <200 mA load |
| BAS70-04 | 70 V VR, 70 mA IF, SOT-23 package, VF = 410 mV @ 10 mA | Higher VR but lower IF; not AEC-Q101 qualified | Use only in low-current industrial signal-path clamping, not power rectification |
Compared with SBAT54LT1G and BAS70-04, the BAS5202VE6127XT uniquely combines AEC-Q101 qualification, 750 mA current capacity, and SC79 footprint - making it the only viable option for automotive-grade medium-current rectification where thermal density and reliability are co-constrained.

FAQ
Is BAS5202VE6127XT pin-compatible with BAS52-02V?
Yes - BAS5202VE6127XT is the tape-and-reel variant (E6127XT suffix) of the BAS52-02V base type, sharing identical SC79 package dimensions, pinout, and electrical specifications. The "E6127XT" denotes 8,000-piece 180 mm reel with 2 mm pitch, per Infineon's standard packing code.
What is the maximum allowable soldering temperature for BAS5202VE6127XT?
The device 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 limited to 60–150 seconds to avoid die metallization degradation or package delamination.
Does BAS5202VE6127XT require derating at elevated ambient temperatures?
Yes - forward current must be linearly derated above TA = 25°C. At TA = 85°C, IF is reduced to 450 mA; at TA = 110°C, IF drops to 250 mA. Derating follows the curve in datasheet Figure 4 ("IF = f(TS)"), referenced to soldering point temperature, not ambient.
Can BAS5202VE6127XT be used in reverse-biased Zener-like clamp configurations?
No - this is a Schottky rectifier diode, not a Zener. Its reverse breakdown is not specified or controlled; operation above 45 V VR risks irreversible avalanche failure. For clamping, use dedicated TVS diodes such as P6SMB43A or SMAJ43A with defined breakdown and clamping voltages.
