Product details
Overview
BAV99E6327 from Infineon Technologies is a silicon dual-series switching diode in SC74 (SOT-363) package, rated for 80 V reverse voltage, 200 mA forward current, and 4 ns reverse recovery time, optimized for high-speed signal routing and ESD protection in USB data lines and I²C bus interfaces.
For engineers reviewing the BAV99E6327 datasheet, BAV99E6327 pinout, BAV99E6327 application, or BAV99E6327 equivalent, key selection criteria include its dual-series configuration, low capacitance (1.5 pF), AEC-Q101 qualification, RoHS-compliant lead-free construction, and thermal resistance of ≤260 K/W (junction-to-soldering point).
Technical Context
The BAV99E6327 integrates two identical high-speed switching diodes in series within a single SC74 package, enabling bidirectional clamping and polarity-insensitive transient suppression. Its 1.5 pF diode capacitance at 0 V and 1 MHz supports signal integrity in 10–100 Mbps digital interfaces.
With a reverse recovery time of 4 ns under 10 mA/10 mA test conditions and a maximum junction temperature of 150 °C, it sustains reliable operation in automotive infotainment and industrial sensor interface circuits where fast edge rates and thermal cycling are present.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed dual-diode clamping applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99LT1G | Same electrical specs; SOT-23-6 package with different pinout (pins 1/2/3 = anode/cathode/common; pins 4/5/6 = common/cathode/anode). | Requires PCB layout revision due to non-matching pin mapping; not drop-in compatible. | Select when sourcing flexibility is prioritized over board reuse; verify trace routing for pin 3/4 common node. |
| EMD2P5R | Higher VF (1.1 V @ 100 mA); 2.5 pF CT; same 4 ns trr and 80 V VR rating. | Increased forward drop reduces margin in low-voltage 1.8 V I/O rails; higher capacitance degrades >50 MHz signal edges. | Prefer only in cost-sensitive industrial designs where 1.8 V compatibility is not required and bandwidth <20 MHz. |
Compared with BAV99E6327, BAV99LT1G demands layout changes but offers identical performance, while EMD2P5R trades lower cost for reduced high-frequency fidelity and tighter voltage margin-making BAV99E6327 optimal for automotive and USB-critical designs.

FAQ
Is BAV99E6327 pin-compatible with BAV99W?
No. BAV99E6327 uses SC74 (SOT-363) packaging with a dual-series internal connection (pins 1–2 and 5–6), whereas BAV99W is in SOT-323 with a single-diode configuration. Their pin counts, assignments, and internal topology differ fundamentally-PCB redesign is required for substitution.
What is the maximum peak forward surge current for BAV99E6327?
The non-repetitive peak surge forward current is 4.5 A for 1 µs pulse width, 1 A for 1 ms, and 0.75 A for 1 s double-pulse condition. These values assume TA = 25 °C and are defined in the Absolute Maximum Ratings table of the official Infineon datasheet Rev. 2.2.
Does BAV99E6327 support bidirectional ESD protection?
Yes. Its dual-series configuration enables symmetrical clamping: when voltage exceeds VF in either direction, one diode conducts while the other blocks, limiting excursion to ~1.4 V across the pair-ideal for protecting bidirectional buses like I²C and USB D+/D− without polarity constraints.
Can BAV99E6327 be used in 1.8 V logic interfaces?
Yes, with design consideration. At IF = 1 mA, VF is 715 mV typ; at 100 mA, it rises to 1200 mV max. In 1.8 V systems, ensure the clamped voltage (VF × 2 ≈ 1.4–2.4 V) remains below the absolute maximum input rating of the protected IC, and verify timing margins under worst-case VF drift at elevated temperature.
