Product details
Overview
BAV199,215 from Nexperia is a low-leakage double diode in SOT23 package with series-connected diodes, 75 V continuous reverse voltage, 3 pA typical reverse current at 150 °C, and 0.8 µs typical reverse recovery time-used in precision signal routing and bias networks of RF front-ends and sensor interfaces.
For engineers reviewing the BAV199,215 datasheet, BAV199,215 pinout, BAV199,215 application, or BAV199,215 equivalent, key selection criteria include ultra-low leakage at high temperature, dual-diode series topology for voltage doubling or polarity control, and SOT23 footprint compatibility with space-constrained PCB layouts.
Technical Context
The BAV199,215 integrates two epitaxial silicon switching diodes in series within a single SOT23-3 package, enabling bidirectional clamping or cascaded voltage thresholding without external interconnects. Its 3 pA typical IR at VR = 75 V and Tj = 150 °C supports stable operation in thermally demanding environments.
With 0.8 µs typical trr and 2 pF typical junction capacitance at 0 V, it delivers medium-speed switching performance while minimizing parasitic loading on high-impedance nodes-critical for sample-and-hold circuits and analog multiplexer protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 75 V max - sets maximum DC blocking capability per diode in series configuration |
| Reverse Current (IR) | 3 pA typ. at VR = 75 V, Tj = 150 °C - enables nanoamp-level leakage-critical bias networks |
| Reverse Recovery Time (trr) | 0.8 µs typ. - supports switching up to ~500 kHz with minimal tail current in signal path |
| Junction Capacitance (Cd) | 2 pF typ. at VR = 0 V, f = 1 MHz - minimizes capacitive loading on RF or high-Z analog nodes |
| Forward Voltage (VF) | 1.25 V max at IF = 150 mA, Tj = 25 °C - defines conduction loss under moderate pulsed load |
| Thermal Resistance (Rth(j-a)) | 500 K/W - requires thermal-aware layout on FR4 for sustained >100 mA operation |
Pinout & Package
SOT23-3 plastic surface-mount package: 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch, standard footprint compatible with reflow and wave soldering per Nexperia's sot023_fr and sot023_fw guidelines.
| 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 supply rail |
| 2 | K2 (cathode of diode 2) | Output node of second diode; defines final polarity and voltage drop across both junctions |
| 3 | K1/A2 (cathode of diode 1 & anode of diode 2) | Internal series connection point-electrically inaccessible and not routable on PCB |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low leakage current | 3 pA typical at 150 °C enables stable DC bias in high-temperature sensor front-ends |
| Series-connected dual diode | Eliminates external wiring between diodes-reduces parasitic inductance and layout area |
| Medium-speed switching | 0.8 µs trr supports clean transitions in clock distribution and pulse shaping circuits |
| Low junction capacitance | 2 pF typical minimizes signal distortion in RF detector and mixer applications |
Applications
| RF Signal Detector | Precision Bias Network |
|---|---|
Use Scenario: Demodulating weak RF signals in AM receivers and envelope detectors. IC Role / Device Role / Timing Role: Dual-diode series configuration acts as synchronous rectifier with matched junction characteristics. Use Value: 2 pF capacitance and sub-nA leakage preserve signal integrity and dynamic range at 10–100 MHz. | Use Scenario: Providing temperature-stable reference bias for op-amp input stages and ADC drivers. IC Role / Device Role / Timing Role: Low-leakage series diodes generate precise forward-voltage-derived bias voltage. Use Value: 3 pA IR at 150 °C ensures <0.1% drift in bias current over industrial temperature range. |
| Analog Multiplexer Protection | High-Voltage Clamping |
Use Scenario: Protecting CMOS analog switches from ESD and overvoltage transients. IC Role / Device Role / Timing Role: Series diodes clamp input to ±1.2 V while limiting leakage into sensitive switch terminals. Use Value: 0.8 µs trr prevents latch-up during fast transients; 75 V VR withstands system-level surge events. | Use Scenario: Limiting voltage excursions in power supply feedback loops and DAC output buffers. IC Role / Device Role / Timing Role: Cascaded diodes provide 1.5 V forward threshold and 85 V peak reverse standoff. Use Value: 85 V VRRM allows safe operation in 48 V industrial bus monitoring circuits with margin. |
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 |
|---|---|---|---|
| BAV21,215 | Higher IR (5 nA typ. at 150 °C), same SOT23-3 pinout | Less suitable for nanoamp-bias circuits but adequate for general-purpose clamping | Select when leakage tolerance >1 nA and cost sensitivity outweighs precision requirements |
| MMBD1204 | Lower VR (100 V), higher trr (4 µs), same series topology | Better voltage rating but slower recovery limits use in >100 kHz signal paths | Prefer for high-voltage transient suppression where speed is secondary to standoff |
Compared with BAV21,215 and MMBD1204, the BAV199,215 uniquely balances ultra-low leakage, medium-speed recovery, and compact SOT23 integration-making it optimal for precision analog and RF signal conditioning where both leakage and timing matter.

FAQ
What is the maximum continuous reverse voltage rating for BAV199,215?
The BAV199,215 has a maximum continuous reverse voltage (VR) of 75 V per diode. This rating applies under steady-state DC conditions at ambient temperatures up to 150 °C, with derating required above Tamb = 25 °C per Figure 1 in the datasheet. Exceeding this value risks permanent junction breakdown.
How does the internal series connection affect forward voltage behavior?
Because the two diodes are connected in series internally, the total forward voltage drop is approximately twice that of a single diode-e.g., ~2.5 V at 150 mA. Pin 1 (A1) to Pin 2 (K2) conducts only when both junctions are forward-biased, and no current flows through the inaccessible Pin 3 (K1/A2) node.
Is BAV199,215 qualified for automotive applications?
No. The BAV199,215 is explicitly designated as non-automotive in its revision history (v.4, April 2023). It lacks AEC-Q101 qualification, automotive-grade screening, and extended temperature validation beyond 150 °C junction limit. For automotive use, consult Nexperia's -Q qualified equivalents like BAV199W-Q.
Can BAV199,215 be used in place of a single diode by connecting only two pins?
No. The device requires all three pins for functional operation: Pin 1 (A1) and Pin 2 (K2) define the overall series path, while Pin 3 (K1/A2) is the mandatory internal interconnection node. Leaving Pin 3 unconnected breaks the circuit; using only two pins results in open-circuit behavior.
