Infineon Technologies BAV199E6327HTSA1

Overview

BAV199E6327HTSA1 from Infineon Technologies is a silicon dual low-leakage switching diode in SOT-23 package, configured as two anode-common diodes with 80 V reverse voltage rating, 200 mA forward current, and 0.6 µs typical reverse recovery time-used in automotive signal clamping and ESD protection circuits.

For engineers reviewing the BAV199E6327HTSA1 datasheet, BAV199E6327HTSA1 pinout, BAV199E6327HTSA1 application, or BAV199E6327HTSA1 equivalent, key selection criteria include reverse leakage at 150°C (≤80 nA), VF at 10 mA (≤1.0 V), series dual configuration, AEC-Q101 qualification, and SOT-23 thermal resistance (RthJS ≤ 360 K/W).

Technical Context

This dual diode integrates two independent P-N junctions sharing a common anode terminal (Pin 1), enabling bidirectional clamping or dual-path signal routing in compact layouts. Its low IR (5 nA @ 75 V, 25°C; 80 nA @ 75 V, 150°C) supports precision bias networks and high-impedance sensor interfaces.

The device exhibits fast switching behavior with trr = 0.6–1.5 µs under IF/IR = 10 mA, and maintains stable VF across temperature (900–1250 mV from 1–150 mA at 25°C). RthJS ≤ 360 K/W enables reliable operation up to Tj = 150°C in thermally constrained automotive modules.

FAQ

What is the pin configuration of BAV199E6327HTSA1?

BAV199E6327HTSA1 uses an anode-common dual-diode configuration in SOT-23: Pin 1 is the shared anode, Pin 2 is Cathode 1, and Pin 3 is Cathode 2. This layout enables bidirectional clamping or independent cathode routing without external interconnects.

Is BAV199E6327HTSA1 suitable for 48 V automotive systems?

No-its 80 V VR rating is insufficient for sustained operation in 48 V architectures where load dump can exceed 100 V. It is validated for 12 V and 24 V systems per AEC-Q101; for 48 V, consider higher-VR alternatives like BAV99W or BAS16XV2.

How does its leakage compare to standard small-signal diodes at 150°C?

At 75 V and 150°C, BAV199E6327HTSA1 specifies IR ≤ 80 nA-up to 10× lower than typical small-signal diodes (e.g., 1N4148: ~500–800 nA). This enables stable biasing in high-temperature engine control modules where leakage-induced offset must be minimized.

Can it replace a single BAV99 in circuit design?

No-BAV99 is cathode-common, while BAV199E6327HTSA1 is anode-common. Swapping requires schematic revision to maintain correct polarity. Functionally identical dual-diode performance exists, but pinout and internal topology differ; direct replacement is not electrically or mechanically feasible.
