Product details
Overview
BAV199W from Nexperia is a low-leakage, medium-speed switching double diode in SOT323 (SC-70) package, with diodes connected in series. It delivers typ. 3 pA reverse current at 75 V, 0.8 µs reverse recovery time, and supports 500 mA repetitive peak forward current - used in precision signal routing and low-current bias networks in compact SMD designs.
For engineers reviewing the BAV199W datasheet, BAV199W pinout, BAV199W application, or BAV199W equivalent, key selection criteria include ultra-low IR for leakage-sensitive analog front-ends, series-connected dual-diode topology for voltage stacking or polarity control, and thermal derating behavior on FR4 PCBs.
Technical Context
The BAV199W integrates two epitaxial silicon switching diodes in a single SC-70 package with shared terminal (Pin 3 = K1/A2), enabling series configuration without external interconnect. Its 0.8 µs trr and 2 pF capacitance support medium-frequency signal steering up to ~10 MHz.
Thermal performance is defined for FR4 PCB mounting: Rth(j-sp) = 400 K/W to solder point, limiting continuous forward current to 110 mA when both diodes are loaded at Tsp = 90 °C - critical for thermally constrained portable and sensor interface layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 75 V max - sets maximum DC blocking capability per diode in series string |
| Reverse Current (IR) | 3 pA typ. at VR = 75 V, Tj = 25 °C - enables nanoamp-level bias stability in high-impedance nodes |
| Reverse Recovery Time (trr) | 0.8 µs typ. - supports clean switching in 1–5 MHz clock or signal routing applications |
| Forward Voltage (VF) | 0.9 V max at IF = 1 mA - ensures minimal voltage drop in low-current sensing or clamping paths |
| Diode Capacitance (Cd) | 2 pF typ. at VR = 0 V, f = 1 MHz - preserves signal integrity in RF-coupled or high-speed sample-hold circuits |
| Repetitive Peak Forward Current (IFRM) | 500 mA - allows short-duration pulse handling in transient protection or level-shifting functions |
Pinout & Package
SOT323 (SC-70) plastic surface-mount package: 3-terminal, 1.3 mm pitch, 2.0 mm × 1.25 mm × 0.95 mm body, optimized for reflow soldering on standard FR4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A1 (anode of diode 1) | Input node for first diode in series chain; connects to signal source or bias rail |
| 2 | K2 (cathode of diode 2) | Output node of second diode; defines final polarity and voltage drop of series pair |
| 3 | K1/A2 (cathode of diode 1 & anode of diode 2) | Internal series junction - no external connection; enables monolithic dual-diode stacking |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low reverse leakage | 3 pA typical at 75 V - maintains accuracy in high-Z feedback, reference, or sensor conditioning paths |
| Series-connected dual-diode topology | Single-package 2-diode stack (A1→K1/A2→K2) - eliminates board space and parasitic inductance of discrete wiring |
| Medium-speed switching | 0.8 µs trr - balances speed and low capacitance for <10 MHz signal routing without ringing |
| FR4-optimized thermal design | Rth(j-sp) = 400 K/W - enables predictable derating for dual-diode conduction on standard PCBs |
Applications
| High-Impedance Sensor Biasing | Precision Reference Clamping |
|---|---|
|
Use Scenario: Biasing photodiode or MEMS sensor output stages where input leakage must remain below 10 pA. IC Role / Device Role / Timing Role: Low-leakage series diode pair provides stable DC offset while blocking reverse current from op-amp inputs. Use Value: 3 pA IR ensures sensor offset drift remains under 1 µV/°C in 1 GΩ transimpedance amplifiers. |
Use Scenario: Clamping voltage references (e.g., bandgap outputs) to prevent overvoltage during power sequencing. IC Role / Device Role / Timing Role: Dual-diode stack limits excursion to ±1.2 V while maintaining sub-nA leakage into reference node. Use Value: 0.9 V VF at 1 mA ensures clamping threshold stays within 2% of nominal reference voltage. |
| RF Signal Routing Switch | Low-Power Level Shifting |
|
Use Scenario: Steering 2.4 GHz ISM-band receive signals between antenna and LNA using passive diode switching. IC Role / Device Role / Timing Role: Series diode pair acts as low-capacitance (2 pF), fast-recovery (0.8 µs) RF path selector. Use Value: 2 pF Cd minimizes insertion loss below –0.3 dB at 2.4 GHz; trr avoids harmonic distortion in pulsed RX mode. |
Use Scenario: Translating logic levels between 1.8 V microcontroller I/O and 3.3 V peripheral interface. IC Role / Device Role / Timing Role: Diode-connected series pair drops ~1.8 V to shift thresholds while blocking reverse current. Use Value: 500 mA IFRM supports 100 mA burst currents during bus arbitration without thermal runaway. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar low-leakage dual-diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV21W,115 | Higher IR (5 nA typ. at 75 V), same SOT323 package and pinout | Less suitable for sub-10 pA bias networks; acceptable for general-purpose clamping | Select when leakage tolerance >1 nA and cost sensitivity outweighs ultra-low-IR requirement |
| FDL100,115 | Lower trr (0.4 µs), higher VF (1.25 V typ.), same VR rating | Better for faster switching but increases forward drop in low-voltage rails | Prefer when signal edge rate >50 V/ns dominates over bias current error budget |
Compared with BAV21W and FDL100, the BAV199W uniquely balances ultra-low leakage (3 pA) with medium-speed recovery (0.8 µs) and low VF (0.9 V), making it optimal for precision analog interfaces where both DC accuracy and moderate AC response matter.

FAQ
What is the maximum continuous forward current for BAV199W when both diodes are conducting?
When both diodes are loaded on an FR4 PCB at Tsp = 90 °C, the maximum continuous forward current is 110 mA. This value is thermally limited by Rth(j-sp) = 400 K/W and total power dissipation of 250 mW - exceeding this requires active cooling or reduced ambient temperature.
Can BAV199W be used in automotive applications?
No. The BAV199W is explicitly designated as non-automotive qualified per Nexperia's revision history (v.4, Oct 2022). It lacks AEC-Q101 qualification, automotive-grade screening, and extended temperature validation beyond 150 °C junction rating.
How does the shared Pin 3 (K1/A2) affect PCB layout?
Pin 3 is the internal connection between cathode of diode 1 and anode of diode 2 - it must remain unconnected externally. Layout must avoid routing traces to Pin 3; only Pins 1 (A1) and 2 (K2) serve as functional terminals for the series diode string.
Is BAV199W compatible with lead-free reflow profiles?
Yes. The SOT323 package is rated for standard IPC/JEDEC J-STD-020 lead-free reflow, with peak temperature up to 260 °C. Nexperia's recommended profile includes ramp rates ≤3 °C/s, soak at 150–200 °C for 60–120 s, and time above liquidus of 60–90 s.
