Product details
Overview
BAV99/LF1VL 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 and cathode of D2). It delivers trr ≤ 4 ns reverse recovery time, Cd ≤ 1.5 pF capacitance at 1 MHz/0 V, 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/LF1VL datasheet, BAV99/LF1VL pinout, BAV99/LF1VL application, or BAV99/LF1VL equivalent, this page provides verified electrical parameters, validated SOT23 pin mapping, automotive-grade AEC-Q101 qualification status, and real-world use cases in ESD-clamped logic interfaces and flyback snubber networks.
Technical Context
The BAV99/LF1VL implements a dual-series diode configuration where Pin 1 is anode of Diode 1, Pin 2 is cathode of Diode 2, and Pin 3 serves as shared cathode/anode node. This topology supports bidirectional clamping and low-inductance series switching in high-frequency signal paths.
Its 4 ns trr and 1.5 pF Cd are measured under standardized conditions (IF/IR = 10 mA, RL = 100 Ω, IR = 1 mA), and thermal resistance Rth(j-a) is 500 K/W in free air - confirming suitability for thermally constrained SMT layouts with minimal heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse voltage (VR) | 100 V - supports input stage protection in 48 V industrial power rails without derating. |
| Reverse recovery time (trr) | ≤ 4 ns - enables clean switching up to 100 MHz in RF detector and sample-hold circuits. |
| Diode capacitance (Cd) | ≤ 1.5 pF at 1 MHz/0 V - minimizes signal loading in high-impedance analog front-ends. |
| Forward voltage (VF) | 855 mV at IF = 10 mA - ensures low conduction loss in low-current bias and clamp networks. |
| Reverse current (IR) | 0.5 μA at VR = 80 V - maintains high isolation in precision reference and sensor signal conditioning. |
| Forward current (IF) | 215 mA continuous - sufficient for driving LED indicators or small-signal relay coils. |
| Junction temperature (Tj) | 150 °C maximum - allows operation in under-hood automotive environments. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package with 3 leads; 2.8 mm × 1.4 mm footprint, 1.1 mm height; JEDEC-compliant for automated placement and reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 | Input node for forward conduction path D1; connects to signal source or supply rail. |
| 2 | Cathode of Diode 2 | Output node for forward conduction path D2; routes clamped or switched signal to load. |
| 3 | Shared cathode (D1) / anode (D2) | Internal connection point enabling series diode operation; used for bidirectional clamping or level shifting. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and body electronics. |
| Low leakage current | IR ≤ 0.5 μA at 80 V enables stable DC biasing in high-gain amplifier stages. |
| Small SMD package | SOT23 footprint saves >60% board area vs. SO-8 equivalents in space-constrained IoT modules. |
| High-speed switching | trr ≤ 4 ns supports clean edge transitions in 50–100 MHz clock distribution and data line termination. |
| Low capacitance | Cd ≤ 1.5 pF prevents signal integrity degradation in USB 2.0 and CAN FD transceiver I/O protection. |
Applications
| USB 2.0 Data Line Protection | Automotive CAN Transceiver Clamp |
|---|---|
Use Scenario: Protects D+ and D− lines from ESD events and overvoltage transients in portable device docking stations.

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 package (smaller footprint); IF = 150 mA; Rth(j-a) = 625 K/W. | Better suited for ultra-dense PCBs but requires tighter thermal management. | Select BAV99W only when board area is constrained below 2.2 mm × 1.35 mm and ambient temperature stays ≤ 85 °C. |
| MMBD7000 | Same SOT23 package; trr = 4 ns; Cd = 2.0 pF; VR = 70 V; not AEC-Q101 qualified. | Lacks automotive qualification and has higher capacitance - unsuitable for CAN/USB high-speed lines. | Choose MMBD7000 only for cost-sensitive consumer applications where 70 V VR and non-automotive use are acceptable. |
Compared with BAV99/LF1VL, BAV99W trades thermal performance for size reduction, while MMBD7000 sacrifices reverse voltage rating and automotive compliance for lower unit cost - making BAV99/LF1VL the optimal choice for AEC-Q101–required, 100 V–rated, high-frequency signal routing.

FAQ
What is the maximum reverse voltage rating for BAV99/LF1VL?
The BAV99/LF1VL has a repetitive peak reverse voltage (VRRM) of 100 V, verified per IEC 60134 limiting values. This rating applies per diode under continuous operation at Tj ≤ 150 °C and is confirmed in Table 6 of the official Nexperia datasheet Rev. 8. Exceeding 100 V risks permanent junction breakdown. The BAV99/LF1VL must not be used in circuits where transient spikes exceed this absolute maximum.
Is BAV99/LF1VL qualified for automotive applications?
Yes, the BAV99/LF1VL is AEC-Q101 qualified, as documented in Section 8.1 of the Nexperia BAV99 series datasheet. This qualification covers stress testing for temperature cycling, humidity bias, and mechanical shock - validating its reliability in automotive ECUs, body control modules, and infotainment systems. The BAV99/LF1VL carries full AEC-Q101 certification, not just "designed for" or "suitable for" automotive use.
What is the reverse recovery time (trr) of BAV99/LF1VL and how is it measured?
The BAV99/LF1VL has a typical reverse recovery time (trr) of ≤ 4 ns, measured under standardized conditions: switching from IF = 10 mA to IR = 10 mA with RL = 100 Ω and sampling at IR = 1 mA (footnote [1] in Table 2). This value is confirmed in both Quick Reference Data (Table 2) and Characteristics (Table 8), and reflects actual performance in high-frequency switching nodes - not a theoretical or simulated figure. The BAV99/LF1VL achieves this via optimized epitaxial layer doping and geometry.
Can BAV99/LF1VL replace BAV99 in existing designs?
Yes, BAV99/LF1VL is a direct replacement for legacy BAV99 variants, sharing identical SOT23 package, pinout (Pins 1–3), electrical specifications (VR = 100 V, trr ≤ 4 ns, Cd ≤ 1.5 pF), and thermal characteristics (Rth(j-a) = 500 K/W). The "/LF1VL" suffix denotes Nexperia's post-2017 marking and packaging standard, with no functional or parametric deviation from the original NXP BAV99. Designers may substitute BAV99/LF1VL without layout or schematic changes.
What is the forward voltage drop of BAV99/LF1VL at 10 mA?
The forward voltage (VF) of BAV99/LF1VL is 855 mV maximum at IF = 10 mA and Tamb = 25 °C, as specified in Table 8 of the Nexperia datasheet. This value represents worst-case conduction loss under nominal conditions and is critical for calculating power dissipation (P = VF × IF) in clamp or bias networks. At lower currents (e.g., 1 mA), VF drops to 715 mV max - useful for ultra-low-power sensor interface designs using the BAV99/LF1VL.
