Product details
Overview
BAV99WE6327BTSA1 from Infineon Technologies is a silicon dual-series switching diode in SOT-323 (SC74) 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 low-voltage logic interfaces.
For engineers reviewing the BAV99WE6327BTSA1 datasheet, BAV99WE6327BTSA1 pinout, BAV99WE6327BTSA1 application, or BAV99WE6327BTSA1 equivalent, this device supports fast-switching requirements in compact consumer electronics, automotive body control modules, and industrial I/O protection circuits where low capacitance (1.5 pF) and AEC-Q101 qualification are critical.
Technical Context
This dual-diode configuration connects two anodes to a common cathode (series dual), enabling bidirectional clamping and polarity-insensitive transient suppression. Its 1.5 pF junction capacitance at 0 V and 1 MHz ensures minimal signal distortion in 10–100 Mbps digital interfaces.
The device operates with a maximum forward voltage of 1.25 V at 150 mA and exhibits leakage current ≤0.15 µA at 70 V and 25 °C, supporting stable biasing in low-power sensor front-ends and level-shifting networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 80 V - Supports rail-to-rail clamping in 5 V and 3.3 V systems without breakdown. |
| Reverse Recovery Time (trr) | 4 ns - Enables reliable operation in >10 MHz switching applications such as clock line conditioning. |
| Junction Capacitance (CT) | 1.5 pF @ 0 V, 1 MHz - Minimizes loading on high-speed data lines (e.g., USB 2.0, I²C). |
| Forward Current (IF) | 200 mA DC - Sustains continuous current in LED biasing and logic-level translation paths. |
| Junction Temperature (Tj) | 150 °C - Rated for under-hood automotive environments per AEC-Q101 qualification. |
| Thermal Resistance (RthJS) | 160 K/W - Limits junction-to-solder-point temperature rise during pulsed operation in SC74 footprint. |
Pinout & Package
SOT-323 (SC74) surface-mount package with three terminals: Pin 1 (Anode 1), Pin 2 (Cathode, common), Pin 3 (Anode 2). Symmetric layout allows orientation-agnostic reel placement; no defined Pin 1 marking direction required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Accepts positive input for unidirectional clamping or series switching path. |
| Pin 2 | Common Cathode | Shared return node for both diodes; connects to system ground or reference rail. |
| Pin 3 | Anode of Diode 2 | Enables complementary signal path or bidirectional ESD protection when paired with Pin 1. |
Key Features

FAQ
What is the pin configuration of BAV99WE6327BTSA1?
BAV99WE6327BTSA1 uses a series dual configuration in SOT-323: Pin 1 is Anode 1, Pin 2 is the common Cathode, and Pin 3 is Anode 2. The symmetric SC74 package has no defined Pin 1 orientation in tape-and-reel, allowing flexible placement during automated assembly.
Is BAV99WE6327BTSA1 suitable for automotive applications?
Yes - it is qualified to AEC-Q101 standards, rated for junction temperatures up to 150 °C, and specified for operation across −65 °C to +150 °C storage range. Its low leakage (≤0.15 µA at 70 V) and robust ESD performance make it appropriate for body electronics and infotainment interfaces.
How does the 4 ns reverse recovery time impact circuit design?
A 4 ns trr allows BAV99WE6327BTSA1 to switch cleanly at frequencies up to ~100 MHz, minimizing tail current and cross-conduction in high-speed digital buffers. This enables use in USB 2.0, LVDS, and SPI signal lines without introducing timing skew or overshoot.
Can BAV99WE6327BTSA1 replace single-diode packages like 1N4148 in existing designs?
No - its series dual topology (two anodes, one cathode) differs fundamentally from the single-diode 1N4148. Direct replacement requires schematic and layout revision to accommodate the three-terminal configuration and shared cathode functionality for bidirectional protection.
