Product details
Overview
BAV99WQ-7-F from Diodes Incorporated is a dual high-speed switching diode in SOT323 package, rated for 75 V peak repetitive reverse voltage, 300 mA forward current, and 4.0 ns reverse recovery time. It serves as a compact, AEC-Q101-qualified signal routing or clamping element in automotive infotainment power management and USB data line protection circuits.
For engineers reviewing the BAV99WQ-7-F datasheet, BAV99WQ-7-F pinout, BAV99WQ-7-F application, or BAV99WQ-7-F equivalent, this part supports fast-switching requirements in space-constrained PCB layouts where low capacitance (2.0 pF), low forward voltage (0.55 V @ 1 mA), and thermal robustness (–55°C to +150°C) are critical selection criteria.
Technical Context
The BAV99WQ-7-F integrates two independent silicon switching diodes in a single SOT323 package with common-cathode configuration. Its 4.0 ns reverse recovery time enables use in >10 MHz signal switching, while the 2.0 pF junction capacitance minimizes signal distortion in high-frequency data paths.
Designed for automotive-grade reliability, it operates across –55°C to +150°C with 625°C/W junction-to-ambient thermal resistance on FR-4 board. The device features matte tin-plated alloy 42 leads, moisture sensitivity level 1, and halogen/antimony-free green molding compound compliant with UL 94V-0.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99DW-7-F | Same SOT323 package and electrical specs, but not AEC-Q101 qualified; IR = 50 µA @ 75 V, TJ = +150°C vs. BAV99WQ-7-F's 30 µA | Approved only for commercial/industrial use; unsuitable for PPAP-submission automotive programs | Select when automotive qualification is unnecessary and cost optimization is prioritized |
| NSR0230P2T5G | Lower VF (0.32 V @ 100 mA), higher IF (400 mA), but larger SOD-523 package (1.2 × 0.8 mm); tRR = 3.5 ns | Better for high-current clamping; incompatible with SOT323 land pattern; lacks AEC-Q101 certification | Choose for non-automotive designs needing lower forward drop and higher surge tolerance in same board area |
Compared with BAV99WQ-7-F, the BAV99DW-7-F sacrifices automotive qualification for lower cost, while the NSR0230P2T5G trades package compatibility for improved forward performance-neither offers identical AEC-Q101/SOT323/2.0 pF combination.

FAQ
Is BAV99WQ-7-F pin-compatible with standard BAV99 variants?
Yes - BAV99WQ-7-F uses the same SOT323 package and common-cathode pinout (Anode1–Cathode–Anode2) as BAV99, BAV99W, and BAV99DW series. Mechanical dimensions, pad layout, and terminal polarity match exactly per Diodes' package outline DS30045 Rev. 14.
What is the maximum allowable soldering temperature profile for BAV99WQ-7-F?
BAV99WQ-7-F complies with IPC/JEDEC J-STD-020 moisture sensitivity level 1, permitting peak reflow temperatures up to 260°C for ≤30 seconds. Reflow must follow Diodes' recommended profile with ramp rate ≤3°C/s and time above 217°C limited to 60–150 seconds.
Does BAV99WQ-7-F support bidirectional ESD protection?
No - its common-cathode configuration supports unidirectional clamping: each anode clamps to the shared cathode (typically tied to VCC). For true bidirectional protection, external pull-up/pull-down resistors or complementary diode arrangements are required per IEC 61000-4-2 test setup.
How does the 2.0 pF capacitance affect USB 2.0 signal integrity?
At 480 Mbps, the 2.0 pF junction capacitance contributes <0.1 UI jitter and <0.5 dB insertion loss at 240 MHz, well within USB-IF eye diagram mask requirements. Layout parasitics must remain below 0.3 pF additional capacitance to maintain total line capacitance ≤2.3 pF.
