Product details
Overview
BAV99-7-F from Diodes Incorporated is a dual surface-mount switching diode in SOT23 package, featuring 75 V peak repetitive reverse voltage, 300 mA forward current, 4.0 ns reverse recovery time, and 2.0 pF junction capacitance per element - used for high-speed signal routing and clamping in USB data lines, ESD protection circuits, and logic-level translation interfaces.
For engineers reviewing the BAV99-7-F datasheet, BAV99-7-F pinout, BAV99-7-F application, or BAV99-7-F equivalent, key selection criteria include fast switching performance (trr ≤ 4.0 ns), low capacitance (CT ≤ 2.0 pF), dual-diode configuration in compact SOT23, and RoHS-compliant lead-free construction suitable for automated PCB assembly.
Technical Context
The BAV99-7-F integrates two independent silicon switching diodes in a single SOT23-3 package with common cathode configuration (Pin 1 = Anode A, Pin 2 = Cathode, Pin 3 = Anode B). It operates across –55°C to +150°C and supports fast transient response due to low stored charge and optimized epitaxial structure.
Each diode exhibits matched electrical characteristics: VF ≤ 0.855 V at IF = 10 mA, IR ≤ 2.5 µA at VR = 75 V, and thermal resistance RθJA = 357°C/W on standard 1"×1" 2 oz copper PCB - enabling reliable operation in space-constrained, thermally demanding signal-path applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Package | SOT23-3: 3-pin surface-mount package with 2.4 mm × 1.3 mm footprint, compatible with standard pick-and-place equipment and reflow soldering. |
| VRRM | 75 V: Maximum repetitive reverse voltage per diode - defines safe blocking range for 3.3 V/5 V logic interface clamping and rail-to-rail signal steering. |
| trr | 4.0 ns: Reverse recovery time at IF = IR = 10 mA - ensures minimal switching distortion in >100 MHz digital signal paths and high-frequency data lines. |
| CT | 2.0 pF at VR = 0 V, f = 1 MHz: Junction capacitance per diode - enables low signal loading in USB 2.0, LVDS, and I²C bus protection designs. |
| IFM | 300 mA: Continuous forward current rating - supports sustained conduction in level-shifting and active pull-up circuits without derating below 70°C ambient. |
| RθJA | 357°C/W: Junction-to-ambient thermal resistance - requires minimal copper area for thermal management in consumer and industrial PCB layouts. |
Pinout & Package
SOT23-3 package: 3-terminal plastic molded case with matte tin-plated alloy 42 leadframe; moisture sensitivity level 1 (J-STD-020); weight ≈ 0.008 g; UL 94V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode A | Input node for first switching path - connects to signal source requiring clamping or steering before reaching shared cathode. |
| Pin 2 | Common Cathode | Shared output node for both diodes - ties to reference rail (e.g., VCC or GND) to define clamping threshold or logic level. |
| Pin 3 | Anode of Diode B | Input node for second independent switching path - enables dual-channel protection or bidirectional signal routing in compact layout. |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-cathode diode structure | Enables compact implementation of bidirectional ESD clamp or dual-rail signal conditioning without discrete pairing. |
| 4.0 ns reverse recovery time | Minimizes propagation delay and overshoot in high-speed digital interfaces such as USB D+/D– and HDMI CEC lines. |
| 2.0 pF junction capacitance | Preserves signal integrity in 480 Mbps USB 2.0 and 3.4 Mbps CAN FD data paths by limiting capacitive loading. |
| Lead-free, halogen-free "Green" construction | Meets RoHS 3 (2015/863/EU) and automotive-grade material compliance requirements without compromising thermal or electrical performance. |
Applications
| USB 2.0 Data Line Protection | Logic-Level Translation Interface |
|---|---|
Use Scenario: Protecting D+ and D– lines against ESD transients and overvoltage during hot-plug events in portable devices. IC Role / Device Role / Timing Role: Dual-diode clamping device with common cathode tied to 3.3 V rail - shunts ±8 kV HBM transients while maintaining <2 pF signal path capacitance. Use Value: Prevents damage to USB PHY ICs without degrading eye diagram margin or violating USB 2.0 rise/fall time specs (≤ 2 ns). | Use Scenario: Translating 1.8 V GPIO signals to 3.3 V microcontroller inputs in mixed-voltage embedded systems. IC Role / Device Role / Timing Role: Passive level shifter using forward-biased diode drop - enables bidirectional voltage translation with no external bias or power supply. Use Value: Eliminates need for active translators in low-speed control lines (e.g., reset, interrupt), reducing BOM count and board area. |
| RS-232 Line Receiver Clamping | Industrial Sensor Signal Conditioning |
Use Scenario: Limiting input voltage excursions on RS-232 receiver inputs exposed to cable-induced surges or ground bounce. IC Role / Device Role / Timing Role: Back-to-back clamping pair (using two BAV99 elements) referenced to ±12 V rails - clips transients beyond ±15 V while passing valid ±3 V to ±15 V data. Use Value: Extends receiver IC lifetime in noisy factory environments without adding propagation delay or requiring additional drivers. | Use Scenario: Isolating analog sensor outputs (e.g., thermistor, RTD bridge) from MCU ADC inputs against EMI-induced spikes. IC Role / Device Role / Timing Role: Low-leakage front-end clamp - IR ≤ 2.5 µA at 75 V reverse bias prevents DC offset drift in precision 16-bit ADC measurement chains. Use Value: Maintains <0.01% gain error stability over temperature (–40°C to +85°C) while providing ±15 kV contact ESD immunity. |
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 (0.9 V @ 10 mA), same trr (4 ns), identical SOT23-3 package and common-cathode topology. | Marginally higher forward drop reduces efficiency in low-voltage bias networks but maintains compatibility in clamping roles. | Select when legacy design validation exists for MMBD7000LT1G and no VF-sensitive biasing is present. |
| 1N4148W-7-F | Single diode in SOD-123; no dual configuration; VF = 0.72 V @ 10 mA, trr = 4 ns, CT = 4 pF - double capacitance per channel. | Requires two devices and extra layout area to replicate dual functionality; unsuitable for space-constrained dual-path designs. | Choose only if existing footprint allows SOD-123 placement and dual-diode integration is not required. |
Compared with MMBD7000LT1G and 1N4148W-7-F, the BAV99-7-F delivers optimal trade-off of dual-channel integration, lowest capacitance (2.0 pF), and proven manufacturability in high-volume SMT lines - making it preferred for USB, I²C, and multi-signal protection where board space and signal fidelity are critical.

FAQ
What is the polarity configuration of the BAV99-7-F?
The BAV99-7-F uses a common-cathode configuration: Pin 1 is Anode A, Pin 2 is the shared Cathode, and Pin 3 is Anode B. This arrangement enables dual-channel clamping to a single reference rail and is confirmed in the internal schematic on page 2 of DS12007 Rev. 29–2.
Is the BAV99-7-F qualified for automotive applications?
No - the BAV99-7-F is not AEC-Q101 qualified. Only the BAV99Q variant (e.g., BAV99Q-7-F) carries AEC-Q101 qualification, PPAP capability, and IATF 16949 manufacturing certification. The -7-F suffix denotes commercial-grade packaging and screening.
Can the BAV99-7-F replace a single 1N4148 in circuit designs?
Yes, one diode section (e.g., Pins 1–2 or Pins 2–3) can substitute for a 1N4148 in low-current switching roles, provided layout accommodates SOT23-3 pinout and the unused anode is left unconnected. Electrical specs (VF, trr, VRRM) are closely matched, though BAV99 has lower CT (2.0 pF vs. ~4 pF).
What is the maximum operating temperature for continuous use?
The BAV99-7-F supports continuous operation from –55°C to +150°C junction temperature. At 70°C ambient on a standard 1"×1" 2 oz copper PCB, its 350 mW power dissipation limit allows up to 250 mA forward current before thermal derating begins, per Figure 1 in DS12007.
