Product details
Overview
BAV99-13-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 - optimized for high-speed signal routing and polarity protection in compact DC-DC converter feedback paths.
For engineers reviewing the BAV99-13-F datasheet, BAV99-13-F pinout, BAV99-13-F application, or BAV99-13-F equivalent, this part supports fast-switching requirements in space-constrained power management, ESD-critical I/O interface clamping, and bidirectional logic-level translation where low capacitance and consistent dual-element matching are essential.
Technical Context
The BAV99-13-F integrates two independent silicon switching diodes in a single SOT23-3 package with common-cathode configuration (Pin 1: Anode 1, Pin 2: Cathode, Pin 3: Anode 2). Its 4.0 ns trr enables operation up to ~80 MHz in clipping/clamping circuits without significant phase lag.
Each diode exhibits matched VF characteristics (≤0.855 V @ 10 mA) and tightly controlled reverse leakage (≤2.5 µA @ 75 V), supporting balanced performance in dual-path signal conditioning and redundant protection schemes across industrial and consumer-grade PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Package | SOT23-3: 2.9 mm × 1.3 mm footprint, compatible with standard pick-and-place and reflow profiles (MSL Level 1). |
| VRWM | 75 V: Supports reliable blocking in 24 V and 48 V industrial bus interfaces without derating at +85°C ambient. |
| IF | 300 mA continuous: Sustains steady-state current in LED biasing, level-shifter pull-up paths, and low-power signal steering. |
| trr | 4.0 ns: Enables clean edge transitions in 10–50 MHz clock line clamping and RF detector applications. |
| CT | 2.0 pF @ 0 V: Minimizes signal distortion in high-impedance analog switch nodes and high-frequency data line protection. |
| VF | 0.855 V @ 10 mA: Ensures predictable forward drop in precision reference path isolation and active pull-down networks. |
Pinout & Package
SOT23-3 plastic package with matte tin-plated alloy 42 leadframe; 0.008 g mass; UL 94V-0 rated molding compound; polarity marked by cathode bar adjacent to Pin 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Input node for first switching path; connects to signal source or supply rail requiring unidirectional conduction. |
| Pin 2 | Common Cathode | Shared return node for both diodes; ties to ground, reference voltage, or negative rail in clamp/steering configurations. |
| Pin 3 | Anode of Diode 2 | Input node for second independent switching path; enables dual-signal handling without cross-talk. |
Key Features
| Feature | Design Value |
|---|---|
| Fast switching speed | 4.0 ns reverse recovery time ensures minimal propagation delay in 10–100 MHz digital signal clamping. |
| Dual-diode integration | Matched electrical parameters between elements reduce skew in differential signal protection and bidirectional level shifting. |
| Green RoHS-compliant construction | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) meets IPC-1752A Class 1 reporting requirements. |
| SOT23 surface-mount compatibility | Standardized footprint allows automated placement and reflow soldering without thermal stress on adjacent components. |
Applications
| USB Data Line Protection | DC-DC Converter Feedback Path |
|---|---|
Use Scenario: Clamping transient overvoltage on USB 2.0 D+ and D− lines during hot-plug events or ESD discharge. IC Role / Device Role / Timing Role: Dual-diode clamp referenced to VBUS and GND, leveraging matched VF and low CT to preserve signal integrity up to 480 Mbps. Use Value: 2.0 pF capacitance avoids signal rise-time degradation; 4.0 ns trr prevents latch-up during fast transients. | Use Scenario: Isolating feedback resistor divider from optocoupler output in isolated flyback converters. IC Role / Device Role / Timing Role: Fast-recovery diode pair preventing reverse current flow from compensation network into error amplifier output. Use Value: 75 V VRWM withstands reflected flyback spikes; 300 mA IF handles typical bias currents without thermal runaway. |
| Logic-Level Translation | Redundant Signal Steering |
Use Scenario: Bidirectional voltage translation between 3.3 V MCU GPIO and 5 V peripheral I²C bus. IC Role / Device Role / Timing Role: Common-cathode dual diode enabling passive level shift with external pull-ups on both sides. Use Value: Matched VF (≤0.855 V @ 10 mA) ensures symmetric high/low threshold alignment across channels. | Use Scenario: Routing critical control signals through parallel paths with automatic failover in safety-monitoring circuits. IC Role / Device Role / Timing Role: Dual-anode configuration allows independent signal injection while sharing cathode return for fault detection. Use Value: Tight IR matching (≤2.5 µA @ 75 V) guarantees consistent leakage behavior under standby conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBD7000-7-F | Higher VRWM (100 V), slower trr (6.0 ns), same SOT23-3 package. | Better suited for 48 V automotive CAN bus protection; less ideal for >25 MHz signal paths. | Select when higher reverse voltage margin outweighs speed requirement. |
| 1N4148W-7-F | Single diode, same VF/trr, but requires two devices and larger board area. | Used where layout flexibility or discrete replacement is preferred over integrated dual function. | Choose only if dual-element matching is not required and space permits separate placement. |
Compared with MMBD7000-7-F and 1N4148W-7-F, the BAV99-13-F delivers optimal balance of speed, integration density, and matched dual-channel performance - making it preferred for space-constrained, high-frequency signal routing where element-to-element consistency matters.

FAQ
What is the maximum operating temperature for BAV99-13-F?
The BAV99-13-F has an operating junction temperature range of −55 °C to +150 °C. At +150 °C ambient, its reverse leakage remains ≤50 µA at 75 V, and power dissipation must be limited to ≤100 mW per diode using the derating curve (357 °C/W RθJA).
Is BAV99-13-F pin-compatible with BAV99-7-F?
Yes - both share identical SOT23-3 packaging, pinout (Anode1–Cathode–Anode2), and electrical specifications. The only difference is tape-and-reel quantity: BAV99-13-F ships in 10,000-unit reels versus 3,000 units for BAV99-7-F.
Does BAV99-13-F meet automotive qualification standards?
No - the standard BAV99-13-F is not AEC-Q101 qualified. For automotive use, Diodes offers the BAV99Q-13-F variant, which is AEC-Q101 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities.
How does the common-cathode configuration affect circuit design?
The shared cathode (Pin 2) simplifies grounding in clamp circuits and enables symmetrical dual-path designs - e.g., one diode clamps positive transients to VCC, the other clamps negative transients to GND, both referencing the same cathode node for coordinated response timing.
