Product details
Overview
BAV99W-7 from Diodes Incorporated is a dual surface-mount switching diode in SOT323 package, featuring 75 V peak repetitive reverse voltage, 300 mA forward current, and 4.0 ns reverse recovery time. It serves as a high-speed signal routing or clamping element in low-voltage digital logic interfaces, USB data lines, and ESD protection circuits.
For engineers reviewing the BAV99W-7 datasheet, BAV99W-7 pinout, BAV99W-7 application, or BAV99W-7 equivalent, key selection criteria include fast tRR performance, dual-common-cathode configuration, SOT323 footprint compatibility, and automotive-grade variant availability (BAV99WQ).
Technical Context
The BAV99W integrates two independent silicon switching diodes in a single SOT323 package with common cathode connection. Its internal structure enables bidirectional clamping and series switching in compact signal-path designs.
Designed for general-purpose high-speed switching, it operates across –55°C to +150°C with 625°C/W junction-to-ambient thermal resistance on standard FR-4 PCBs. The device meets J-STD-020 moisture sensitivity Level 1 and supports reflow soldering per MIL-STD-202.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBD7000LT1G | Higher VF (0.75 V @ 10 mA), same SOT-23 package, 30 V VRRM | Limited to ≤30 V systems; unsuitable for 48 V or 75 V clamping | Select when lower cost is prioritized and reverse voltage ≤30 V suffices |
| BAT54CW | Lower tRR (3.5 ns), Schottky architecture, 30 V VRRM, higher IR leakage | Not suitable for high-reliability reverse-blocking roles due to 1 µA IR @ 25 V | Choose for ultra-fast switching in ≤30 V logic where leakage tolerance exists |
Compared with BAV99W-7, MMBD7000LT1G offers cost advantage but sacrifices reverse voltage headroom, while BAT54CW delivers faster switching at the expense of leakage-sensitive designs-BAV99W-7 balances speed, blocking, and leakage for broad 3.3–5 V interface protection.

FAQ
What is the pin configuration of BAV99W-7?
BAV99W-7 uses a 3-pin SOT323 package with Pin 1 = Anode 1, Pin 2 = Common Cathode, Pin 3 = Anode 2. This dual-common-cathode arrangement allows independent anode control while sharing a single cathode node for compact layout in bidirectional clamping circuits.
Is BAV99W-7 suitable for automotive applications?
The BAV99W-7 is not AEC-Q101 qualified; however, its automotive-grade variant BAV99WQ-7-F is fully qualified, PPAP-capable, and manufactured in IATF 16949-certified facilities. For production automotive use, BAV99WQ must be specified instead of BAV99W.
How does BAV99W-7 compare to single-diode SOT23 packages?
BAV99W-7 integrates two diodes in one SOT323 footprint, reducing PCB area by ~35% versus two discrete SOT23 devices. Its common-cathode topology simplifies routing in dual-rail clamping applications, though it lacks independent cathode control found in dual-die SOT363 variants.
What is the maximum operating temperature for continuous use?
BAV99W-7 is rated for continuous operation from –55°C to +150°C junction temperature. At ambient temperatures above +70°C, power dissipation must be derated linearly per the published curve: 200 mW at 25°C, zero at 150°C, with 625°C/W thermal resistance on standard FR-4 boards.
