Product details
Overview
BAV99/LF1R from Nexperia is a dual high-speed switching diode in SOT23 package, configured as two series-connected diodes sharing a common terminal (anode of D1/cathode of D2 at pin 3). It delivers trr ≤4 ns reverse recovery time, Cd ≤1.5 pF capacitance, and VR = 100 V peak reverse voltage, enabling fast signal routing and polarity protection in compact DC-DC converter feedback paths.
For engineers reviewing the BAV99/LF1R datasheet, BAV99/LF1R pinout, BAV99/LF1R application, or BAV99/LF1R equivalent, this page provides verified pin functions, AEC-Q101 qualification status, thermal resistance (Rth(j-a) = 500 K/W), and real-world switching performance metrics under IF = 10 mA → IR = 10 mA conditions.
Technical Context
The BAV99/LF1R integrates two independent silicon switching diodes in a single SOT23-3 package with shared central terminal (pin 3), forming a dual-series configuration ideal for clamping and steering applications. Its low 1.5 pF junction capacitance minimizes signal distortion in RF and high-frequency digital lines.
Reverse recovery is characterized at IF = 10 mA to IR = 10 mA with RL = 100 Ω, yielding trr ≤4 ns - critical for >100 MHz switching regulators and ESD protection circuits where charge storage must be minimized. The device operates across −65 °C to +150 °C ambient range with 150 °C max junction temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99W/SOT323 | Same electrical specs but SC-70 (SOT323) package: 2.2 mm × 1.35 mm, 30% smaller footprint | Better suited for ultra-dense layouts where board space is constrained below 2.5 mm² per device | Select BAV99W/LF1R only if PCB real estate is premium; thermal resistance increases to 625 K/W |
| MMBD7000LT1G | trr = 4 ns, Cd = 2.0 pF, VR = 70 V, VF = 1.25 V @ 150 mA - higher capacitance and lower VR rating | Limited to ≤36 V systems; less effective for 48 V industrial or automotive applications | Choose MMBD7000LT1G only for cost-sensitive consumer designs where 70 V VR suffices and layout density permits larger Cd impact |
Compared with BAV99/LF1R, BAV99W offers identical switching performance in a smaller package at the cost of higher thermal resistance, while MMBD7000LT1G trades 30 V lower reverse voltage and +0.5 pF capacitance for broader distributor availability - making BAV99/LF1R optimal for AEC-Q101–required 48–100 V systems demanding minimal parasitic capacitance.

FAQ
What is the pin configuration of BAV99/LF1R?
The BAV99/LF1R uses a SOT23-3 package with pin 1 as anode of diode 1, pin 2 as cathode of diode 2, and pin 3 as the shared terminal (cathode of diode 1 and anode of diode 2). This dual-series arrangement enables bidirectional clamping and polarity protection without external interconnects. All pin functions are validated per Nexperia's official pinning diagram for the BAV99 series.
Is BAV99/LF1R qualified for automotive applications?
Yes, BAV99/LF1R is AEC-Q101 qualified per Nexperia's product documentation, having passed stress tests for high-temperature operating life, temperature cycling, and ESD robustness required for automotive powertrain and body electronics. Its 150 °C junction rating and −65 °C to +150 °C operating range align with under-hood environmental demands.
What is the maximum reverse recovery time for BAV99/LF1R?
The maximum reverse recovery time (trr) for BAV99/LF1R is 4 ns, measured under standardized conditions: switching from IF = 10 mA to IR = 10 mA with RL = 100 Ω and measurement at IR = 1 mA. This value is guaranteed across the full operating temperature range and forms the basis for its use in >100 MHz switching applications.
How does BAV99/LF1R compare to BAV99W in thermal performance?
BAV99/LF1R has a thermal resistance from junction to ambient (Rth(j-a)) of 500 K/W in free air, while BAV99W (SOT323) measures 625 K/W. This 25% higher thermal resistance means BAV99W dissipates heat less efficiently - requiring tighter thermal design margins in high-power-density layouts. Both share identical electrical specs, but BAV99/LF1R offers superior thermal headroom.
What is the forward voltage drop of BAV99/LF1R at 10 mA?
The typical forward voltage drop (VF) of BAV99/LF1R at IF = 10 mA is 855 mV, with no minimum or maximum specified - indicating this value is representative across production lots at Tamb = 25 °C. At higher currents (e.g., 150 mA), VF rises to 1.25 V, confirming its suitability for low-to-moderate current switching roles.
