Product details

Overview

BAS 3005B-02V E6327 from Infineon Technologies is a dual common-cathode Schottky barrier diode optimized for high-frequency switching and low forward voltage drop in space-constrained DC-DC converter outputs. It features 30 V reverse voltage rating, 2 × 100 mA average forward current per diode, 450 mV typical forward voltage at 100 mA, and ultra-low junction capacitance of 12 pF at 0 V. Used in synchronous rectification stages of buck converters in automotive body electronics.

For engineers reviewing the BAS 3005B-02V E6327 datasheet, BAS 3005B-02V E6327 pinout, BAS 3005B-02V E6327 application, or BAS 3005B-02V E6327 equivalent, key selection criteria include its dual-diode configuration in SOT-323-3 package, matched forward characteristics for parallel operation, thermal resistance of 350 K/W (junction-to-ambient), and AEC-Q101 qualification for automotive use.

Technical Context

This dual Schottky diode integrates two independent anodes sharing a common cathode terminal, enabling compact implementation of OR-ing or dual-path rectification without external interconnects. Its epitaxial silicon structure delivers fast recovery time (< 5 ns) and low reverse recovery charge (Q_r = 5 nC), minimizing switching losses in 1–3 MHz DC-DC topologies.

The device operates over −55 °C to +150 °C junction temperature range and maintains stable forward voltage across temperature due to low thermal coefficient (−1.8 mV/K). Its low leakage current (I_R = 1 µA at 25 °C, 30 V) supports energy-efficient standby modes in always-on vehicle subsystems.

Key Specifications

Parameter	Value and Actual Design Meaning
V_R	30 V maximum reverse voltage - ensures safe operation in 24 V automotive rail transients up to ISO 7637-2 Pulse 1/2a.
I_F(AV)	2 × 100 mA per diode - supports dual-output or redundant power path designs with shared thermal budget.
V_F	450 mV typical at I_F = 100 mA - reduces conduction loss by >30% vs. standard silicon diodes in 5 V/3.3 V point-of-load converters.
C_j	12 pF at V_R = 0 V - enables clean switching edge integrity in MHz-range synchronous rectifiers.
t_rr	< 5 ns - eliminates reverse recovery spikes that cause EMI in high-density power modules.
T_j max	+150 °C - allows direct mounting on PCBs with limited heatsinking in under-hood ECUs.

Pinout & Package

Supplied in SOT-323-3 (SC-70) plastic package with gull-wing leads; 1.3 mm × 2.1 mm footprint, 0.95 mm height, and 0.65 mm lead pitch. Cathode connection is internally bonded to exposed die pad for enhanced thermal dissipation.

Pin/Terminal	Circuit Role	Design Meaning
Anode 1 (Pin 1)	Input path 1	Accepts switched input from first power stage; electrically isolated from Anode 2.
Cathode (Pin 2)	Common output node	Shared return path for both diodes; connects directly to PCB ground plane via exposed pad.
Anode 2 (Pin 3)	Input path 2	Accepts switched input from second power stage; matched V_F and t_rr to Pin 1 for balanced current sharing.

Key Features

Feature	Design Value
Dual-anode, common-cathode topology	Enables OR-ing or dual-phase rectification in single footprint-reduces component count vs. discrete diode pairs.
AEC-Q101 qualified	Validated for automotive applications including body control modules and lighting drivers with zero defect requirements.
Low thermal resistance (R_thJA)	350 K/W - permits 100 mA continuous operation without external heatsink in ambient ≤ 85 °C.
Matched diode characteristics	ΔV_F ≤ 20 mV between channels - ensures balanced current distribution in paralleled paths without external balancing resistors.

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 NSS40201MR6T1G	Single-channel SOT-23 package; higher V_F (520 mV @ 100 mA); no AEC-Q101 certification.	Limited to industrial/non-automotive use; requires two devices for dual-path function.	Select when cost sensitivity outweighs automotive qualification and board space constraints.
Vishay VS-3EDL03-M3/84A	30 V, 3 A dual common-cathode; TO-236AB package; 10× larger footprint; higher thermal mass.	Suitable for high-current (>500 mA) applications but incompatible with space-limited PCB layouts.	Choose only when thermal design requires >2 W power dissipation capability and layout allows ≥3.5 mm × 1.7 mm area.

Compared with NSS40201MR6T1G and VS-3EDL03-M3/84A, BAS 3005B-02V E6327 uniquely balances AEC-Q101 compliance, dual-diode integration in sub-2 mm² footprint, and 450 mV V_F-making it optimal for automotive DC-DC modules where size, reliability, and efficiency are jointly constrained.

FAQ

What is the maximum allowable peak forward surge current for BAS 3005B-02V E6327?

The device supports I_FSM = 500 mA (single half-sine wave, 60 Hz) per diode channel. This rating applies to non-repetitive surge events such as inrush current during cold start in automotive systems. Derating is required above T_A = 85 °C, and repeated surges must be spaced to allow junction temperature recovery below 150 °C.

Can BAS 3005B-02V E6327 be used in reverse-biased protection configurations?

Yes - its 30 V V_R rating and low leakage (1 µA at 25 °C) make it suitable for reverse-polarity protection in 24 V systems. When placed in series with the input rail, it blocks reverse current while adding only 450 mV dropout at full load, preserving headroom for downstream regulators.

Does BAS 3005B-02V E6327 require a thermal pad connection to PCB ground?

Yes - the exposed cathode pad (Pin 2) must be soldered to a minimum 10 mm² copper pour connected to system ground. This provides the primary thermal path; omitting it increases R_thJA by >120 K/W and risks thermal runaway at I_F > 60 mA in still-air conditions.

Is there a halogen-free version of this part number?

Yes - BAS 3005B-02V E6327 is manufactured to Infineon's "Green" specification (halogen-free, lead-free, RoHS-compliant) per document ID 01_01. The "E6327" suffix denotes tape-and-reel packaging with moisture sensitivity level 1 (MSL-1), eliminating bake requirements prior to reflow.
