Diodes Incorporated BAV99DWQ-7-F

Overview

BAV99DWQ-7-F from Diodes Incorporated is a dual high-speed switching diode array in SOT363 package, configured as two independent BAV99 circuits (common-cathode pair), with 75 V peak repetitive reverse voltage, 215 mA forward current rating, and 4.0 ns reverse recovery time. It is AEC-Q101 qualified for automotive signal routing and ESD protection in CAN/LIN bus interface circuits.

For engineers reviewing the BAV99DWQ-7-F datasheet, BAV99DWQ-7-F pinout, BAV99DWQ-7-F application, or BAV99DWQ-7-F equivalent, key selection criteria include reverse recovery time, dual common-cathode topology, AEC-Q101 qualification, low capacitance (2.0 pF), and thermal resistance (417 °C/W on alumina).

Technical Context

This dual diode array integrates two independent high-speed switching elements sharing a common cathode terminal per channel (pins 1–2–3 and pins 4–5–6), enabling compact bidirectional clamping or polarity-selective signal steering. Its 4.0 ns t_RR and 2.0 pF C_T support >100 MHz digital signal integrity in automotive serial buses.

The device operates across –65 °C to +150 °C and delivers 300 mW power dissipation on alumina substrate, with thermal resistance optimized for space-constrained engine control and body electronics modules where lead-free, halogen-free compliance is mandatory.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual high-speed switching diode applications.

Compared with BAV99W-7-F, the BAV99DWQ-7-F saves 50% board area and eliminates inter-device matching variance; DMN2041LSD-13 is not a functional substitute due to fundamental device type mismatch and voltage limitation.

FAQ

What is the pin configuration for BAV99DWQ-7-F?

Pins 1 and 3 are anodes for the two diode elements; pins 2 and 4 are their respective cathodes; pins 5 and 6 are internally unconnected and must remain floating. The internal schematic confirms a dual common-cathode arrangement with no shared terminals between channels.

Is BAV99DWQ-7-F suitable for 5 V logic-level clamping?

Yes - its 75 V V_RWM and low 0.715 V V_F @ 1 mA ensure minimal voltage drop and reliable conduction during 5 V rail overvoltage events, while 2.0 pF capacitance avoids loading high-speed GPIO lines.

Does BAV99DWQ-7-F support PPAP documentation?

Yes - as an AEC-Q101-qualified automotive part, it is PPAP capable per Diodes Incorporated's compliance framework; full PPAP Level 3 documentation (including PSW, control plan, MSA, and dimensional reports) is available upon request for qualified OEM programs.

How does thermal performance differ between FR-4 and alumina PCB mounting?

On FR-4, R_θJA is 625 °C/W (200 mW max PD); on alumina, it improves to 417 °C/W (300 mW max PD). This 33% thermal resistance reduction enables higher continuous current in thermally demanding under-hood locations without derating.
