Product details
Overview
BAV99DW-7 from Diodes Incorporated is a dual high-speed switching diode array in SOT363 package, comprising two independent BAV99 circuits. It delivers 75 V peak reverse voltage, 215 mA forward current, 4.0 ns reverse recovery time, and 2.0 pF junction capacitance at 0 V - optimized for signal routing and polarity protection in compact DC-DC converters and USB interface circuits.
For engineers reviewing the BAV99DW-7 datasheet, BAV99DW-7 pinout, BAV99DW-7 application, or BAV99DW-7 equivalent, key selection criteria include reverse recovery speed, low capacitance for high-frequency signal integrity, dual-diode integration for space-constrained board layouts, and AEC-Q qualified reliability for automotive-grade designs.
Technical Context
This dual diode array integrates two independent, matched BAV99 silicon switching diodes in a single SOT363 package. Each diode exhibits fast recovery (tRR ≤ 4.0 ns), low forward voltage (VF ≤ 0.855 V @ 10 mA), and tight leakage control (IR ≤ 2.5 µA @ 75 V).
The device supports bidirectional signal clamping and polarity reversal protection with symmetrical anode-cathode topology per element. Its thermal resistance of 417 °C/W (on alumina PCB) enables stable operation up to +150 °C ambient, meeting JEDEC-referenced high-reliability requirements.

IC Role / Device Role / Timing Role: Fast-switching clamp limiting error amplifier output swing to prevent saturation and improve transient response. Use Value: 75 V VRWM accommodates 24 V input rails; 0.855 V VF @ 10 mA ensures precise voltage thresholding. |
| Automotive CAN Bus Termination | Logic-Level Signal Steering |
Use Scenario: Bidirectional termination and surge suppression on 12 V CAN H/L lines in body control modules. IC Role / Device Role / Timing Role: Dual diode pair providing symmetric clamping to battery and ground, compliant with ISO 11898-2 EMC requirements.

Use Value: Matched VF across both diodes (<0.02 V spread) guarantees consistent logic thresholds in multi-source systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99DWQ-7-F | Identical electrical specs; AEC-Q200 qualified with extended test reporting (HTOL, UHAST) | Required for production automotive ECUs; not needed for industrial prototypes or consumer designs | Select when automotive PPAP documentation and zero-defect field history are mandatory |
| MMBD7000-7-F | Same SOT363 package but single diode; 100 V VRWM, 3.5 ns tRR, 2.5 pF CT | Used where only one diode is needed per location; requires two devices for dual functionality | Choose when board layout permits duplication and higher reverse voltage margin is prioritized over density |
Compared with BAV99DW-7, the BAV99DWQ-7-F adds automotive traceability without performance trade-offs, while MMBD7000-7-F sacrifices integration for higher voltage headroom and slightly slower recovery - making BAV99DW-7 optimal for space-constrained, dual-path signal conditioning.

FAQ
What is the maximum continuous forward current per diode in the BAV99DW-7?
The BAV99DW-7 supports 215 mA continuous forward current per diode when mounted on an FR-4 PCB with specified pad layout. Derating applies above +25 °C ambient, following the 417 °C/W thermal resistance curve on alumina substrates or 625 °C/W on standard FR-4.
Does the BAV99DW-7 have a common cathode or common anode configuration?
The BAV99DW-7 uses a common-anode configuration: pins 5 and 6 are internally tied to the shared anode node, while pins 1/2 and 3/4 form two independent anode–cathode pairs. This enables OR-ing, level shifting, and bidirectional clamping without external wiring.
Is the BAV99DW-7 suitable for automotive applications?
Yes - the BAV99DW-7 meets JEDEC standards referenced in AEC-Q for high reliability and operates from −55 to +150 °C. For certified automotive production, Diodes offers the BAV99DWQ-7-F variant with full AEC-Q200 test reports and PPAP support.
How does the reverse recovery time affect its use in high-frequency circuits?
With tRR ≤ 4.0 ns, the BAV99DW-7 minimizes minority-carrier storage delay, preventing signal ringing and cross-conduction in 50–200 MHz digital and RF signal paths. This makes it suitable for USB 2.0 data line protection and fast-switching DC-DC feedback networks.
