Product details
Overview
BAV99W from Nexperia is a dual high-speed switching diode in SOT323 (SC-70) package, configured as two independent diodes sharing a common terminal (anode of D1 and cathode of D2 tied to pin 3). It delivers trr ≤ 4 ns reverse recovery time, Cd ≤ 1.5 pF capacitance, and VR = 100 V, enabling use in compact, high-frequency signal routing and polarity protection circuits.
For engineers reviewing the BAV99W datasheet, BAV99W pinout, BAV99W application, or BAV99W equivalent, key selection criteria include verified dual-diode topology, sub-4 ns trr at IF = 10 mA/IR = 10 mA, low-leakage operation (IR ≤ 0.5 µA at VR = 80 V), and thermal resistance Rth(j-a) = 625 K/W on FR4 PCB - all critical for space-constrained 5–100 MHz switching designs.
Technical Context
The BAV99W integrates two discrete epitaxial planar diodes in a single SC-70 package with shared terminal (pin 3 = K1/A2), forming a compact dual-diode configuration optimized for bidirectional clamping and series switching. Its silicon process ensures stable trr ≤ 4 ns under standardized test conditions (IF = 10 mA, IR = 10 mA, RL = 100 Ω).
Thermal performance is defined for FR4 PCB mounting: Rth(j-a) = 625 K/W (single diode loaded, free air) and Rth(j-sp) = 300 K/W, supporting continuous IF ≤ 150 mA per diode with VF ≤ 1.25 V at 25 °C. Junction temperature is rated to 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse voltage (VR) | 100 V - supports DC blocking and transient suppression up to industrial 80 V bus levels |
| Reverse recovery time (trr) | ≤ 4 ns - enables reliable operation in 50–100 MHz digital signal routing and RF detector stages |
| Diode capacitance (Cd) | ≤ 1.5 pF at 0 V - minimizes signal loading in high-impedance, high-frequency node applications |
| Forward voltage (VF) | ≤ 855 mV at IF = 10 mA - ensures low conduction loss in low-power logic-level clamping |
| Reverse current (IR) | ≤ 0.5 µA at VR = 80 V, 25 °C - maintains signal integrity in precision analog front-ends |
| Package | SOT323 (SC-70), 2.0 × 1.25 × 0.95 mm - fits 0.5 mm pitch reflow footprints with minimal board area |
Pinout & Package
SOT323 (SC-70) plastic surface-mount package: 3-terminal, 1.3 mm lead pitch, 2.0 mm × 1.25 mm × 0.95 mm body, designed for standard reflow soldering per Figure 8 footprint (2.65 mm × 2.35 mm land pattern).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 (A1) | Input terminal for forward conduction path of first diode; connects to signal source in clamp or switch position |
| 2 | Cathode of Diode 2 (K2) | Output terminal for forward conduction path of second diode; used for polarity-reversal isolation or dual-rail protection |
| 3 | Cathode of Diode 1 / Anode of Diode 2 (K1, A2) | Shared internal node enabling compact dual-diode topology; eliminates need for external interconnect in series-switch configurations |
Key Features
| Feature | Design Value |
|---|---|
| Dual-diode integration in SC-70 | Reduces PCB area by ~40% vs. two discrete SOT23 diodes while maintaining independent anode/cathode access |
| Sub-4 ns reverse recovery | Enables clean edge transitions in 50+ MHz clock distribution and data line steering without ringing |
| 1.5 pF junction capacitance | Limits capacitive loading to <0.5% of typical 50 Ω transmission line impedance at 100 MHz |
| 150 °C max junction temperature | Supports sustained operation in sealed enclosures or near heat-generating ICs without derating below 130 mA |
| 0.5 µA max reverse leakage @ 80 V | Preserves accuracy in high-impedance bias networks and sensor interface circuits over full industrial temp range |
Applications
| High-Speed Signal Routing | Reverse Polarity Protection |
|---|---|
Use Scenario: Steering logic-level clock or data signals between multiple sources and a single receiver in FPGA I/O banks. IC Role / Device Role / Timing Role: Dual-diode acts as bidirectional signal gate, leveraging pin 3 as common node to route either direction without cross-talk. Use Value: 4 ns trr prevents pulse distortion at 50 MHz; 1.5 pF Cd avoids measurable delay skew across parallel lines. |
Use Scenario: Protecting 3.3 V or 5 V microcontroller power inputs against accidental battery reversal in portable instrumentation. IC Role / Device Role / Timing Role: One diode conducts during correct polarity; second blocks reverse current using K2–K1/A2 path. Use Value: 100 V VR rating provides 3× margin over 3.3/5 V rails; 0.5 µA IR ensures <1 µW standby loss. |
| RF Detector Clamping | Logic-Level Translation Interface |
Use Scenario: Limiting input amplitude to ±0.8 V in 2.4 GHz ISM-band envelope detector front-ends. IC Role / Device Role / Timing Role: Diode pair clips positive/negative excursions using A1–K1/A2 and K1/A2–K2 paths. Use Value: Low Cd preserves detector Q-factor; 855 mV VF ensures precise clipping threshold at 10 mA bias. |
Use Scenario: Level-shifting UART TX/RX lines between 1.8 V SoC and 3.3 V peripheral without active circuitry. IC Role / Device Role / Timing Role: Forward-biased diode drops ~0.7 V; reverse-biased diode blocks backfeed during idle states. Use Value: 4 ns trr prevents false edge detection during 2 Mbps UART transitions; SOT323 footprint saves space on dense MCU boards. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99DW | Same die, but marked "A7" instead of "A7%"; identical electrical specs and SOT323 package | No functional difference; marking variation reflects manufacturing site code, not performance or qualification | Select when exact marking compliance is required for traceability or audit purposes |
| MMBD7000LT1G | trr = 4 ns (same), but Cd = 2.5 pF (higher); VR = 70 V (lower); VF = 1.25 V @ 100 mA (higher) | Less suitable for >50 MHz signal routing due to higher capacitance; acceptable for lower-frequency protection | Choose only if BAV99W is unavailable and design operates below 30 MHz with VR ≤ 70 V |
Compared with BAV99W, BAV99DW offers identical performance with minor marking variance, while MMBD7000LT1G trades higher capacitance and lower VR for broader distributor availability - making BAV99W optimal for high-frequency, space-constrained designs requiring 100 V rating and minimal Cd.

FAQ
What is the maximum continuous forward current per diode in the BAV99W?
The BAV99W supports 150 mA continuous forward current per diode at Tamb ≤ 25 °C on FR4 PCB, with derating to 130 mA when both diodes conduct simultaneously. This rating is validated by thermal resistance Rth(j-a) = 625 K/W and Ptot = 200 mW limit, ensuring safe operation without heatsinking in standard layouts.
Is the BAV99W suitable for automotive applications?
No - the BAV99W is explicitly designated as non-automotive qualified per Nexperia's 2022 revision history. It lacks AEC-Q101 qualification, automotive-grade screening, and extended temperature validation beyond −65 °C to +150 °C ambient. For automotive use, Nexperia recommends the BAV99W-Q variant.
How does the shared pin (pin 3) affect circuit layout?
Pin 3 serves as both cathode of diode 1 and anode of diode 2, enabling compact dual-diode configurations like series switches or bidirectional clamps without external traces. Layout must avoid routing conflicting signals to this node; it functions as a fixed internal connection, not a configurable terminal.
Can the BAV99W replace two separate SOT23 diodes in a design?
Yes - the BAV99W replaces two discrete SOT23 diodes in most dual-switching roles, reducing PCB area by ~35% and eliminating one solder joint. However, it cannot replicate independent cathode/anode isolation; designs requiring fully separated diodes (e.g., isolated power domains) must retain discrete parts.
