Product details
Overview
BAV99W/DG/B3,115 from Nexperia is a dual high-speed switching diode in SOT323 (SC-70) package, configured as two independent series-connected diodes sharing a common terminal (anode of D1 / cathode of D2 on pin 3). It delivers trr ≤ 4 ns reverse recovery time, Cd ≤ 1.5 pF capacitance at 1 MHz, and VR = 100 V peak reverse voltage - enabling fast signal routing and polarity protection in compact automotive and industrial PCBs.
For engineers reviewing the BAV99W/DG/B3,115 datasheet, BAV99W/DG/B3,115 pinout, BAV99W/DG/B3,115 application, or BAV99W/DG/B3,115 equivalent, this device is selected for high-frequency clamping, ESD-tolerant I/O protection, and space-constrained dual-diode functions where low leakage (<0.5 μA @ 80 V), AEC-Q101 qualification, and thermal resistance Rth(j-a) = 625 K/W are critical design constraints.
Technical Context
The BAV99W operates as two discrete high-speed PN junction diodes in a single SOT323 package with shared terminal (pin 3), supporting independent forward conduction paths and fast reverse recovery under transient conditions. Its architecture enables bidirectional clamping and rail-to-rail signal steering without cross-coupling.
Designed for operation up to 150 °C junction temperature and qualified per AEC-Q101, it sustains IF = 150 mA continuous forward current per diode and withstands VR = 100 V repetitive reverse voltage - meeting requirements for under-hood automotive sensors and industrial PLC I/O stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Recovery Time (trr) | ≤4 ns - enables reliable operation in >100 MHz switching circuits and high-speed data line protection. |
| Diode Capacitance (Cd) | ≤1.5 pF @ 1 MHz, 0 V - minimizes signal distortion and loading in RF and high-speed digital interfaces. |
| Peak Reverse Voltage (VRRM) | 100 V - supports 24 V and 48 V industrial bus systems with margin against transients. |
| Forward Current (IF) | 150 mA per diode - sufficient for logic-level signal clamping and low-power sensor interface protection. |
| Reverse Leakage (IR) | ≤0.5 μA @ VR = 80 V - ensures low standby power loss in always-on automotive modules. |
| Junction-to-Ambient Rth(j-a) | 625 K/W - defines thermal derating curve for PCB layouts with minimal copper area in SOT323 footprint. |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness. |
Pinout & Package
BAV99W is housed in a SOT323 (SC-70) plastic surface-mount package measuring 2.2 mm × 1.35 mm × 0.95 mm, optimized for high-density placement and reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 | Input node for forward conduction path D1; connects to protected signal or supply rail. |
| 2 | Cathode of Diode 2 | Output node for forward conduction path D2; routes clamped signal to downstream circuitry. |
| 3 | Common terminal (cathode of D1 / anode of D2) | Shared junction enabling series diode configuration - used for bidirectional clamping or level shifting. |
Key Features
| Feature | Design Value |
|---|---|
| High-Speed Switching | trr ≤ 4 ns enables use in 100+ MHz clock/data lines and fast transient suppression. |
| Low Junction Capacitance | Cd ≤ 1.5 pF preserves signal integrity in USB 2.0, CAN FD, and LVDS interfaces. |
| AEC-Q101 Qualification | Validated for automotive applications including engine control, body electronics, and ADAS sensors. |
| Thermal Robustness | Rated for Tj = 150 °C and Tamb = −65 to +150 °C - suitable for under-hood and industrial environments. |
| Small Outline Package | SOT323 footprint (2.2 × 1.35 mm) saves >40% board area vs. SOT23 while maintaining solder joint reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed dual-diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99LT1G (ON Semiconductor) | SOT23-3 package; higher IF = 215 mA; Rth(j-a) = 500 K/W; same trr ≤ 4 ns and Cd ≤ 1.5 pF. | Larger footprint; better thermal performance but occupies 2.5× more board area than SOT323. | Select when higher continuous current or lower thermal resistance is prioritized over miniaturization. |
| MMBD7000LT1G (ON Semiconductor) | SOT23-3; VF = 1.25 V @ 150 mA; trr = 4 ns; Cd = 2.5 pF - higher capacitance degrades >100 MHz signal fidelity. | Not AEC-Q101 qualified; rated only for commercial temperature range (−55 to +150 °C not guaranteed). | Acceptable for cost-sensitive consumer designs where automotive qualification and ultra-low Cd are non-critical. |
Compared with BAV99LT1G, the BAV99W offers 40% smaller footprint and AEC-Q101 compliance at the expense of 65 mA lower IF rating; versus MMBD7000LT1G, it provides tighter capacitance control and automotive qualification but requires stricter layout for thermal management due to higher Rth(j-a).

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, derating linearly to 130 mA at higher ambient temperatures per the limiting values table. This rating assumes single-diode operation with no simultaneous conduction in both diodes.
Is the BAV99W/DG/B3,115 pin-compatible with the standard BAV99 in SOT23?
No - the BAV99W uses SOT323 (3-pin SC-70) with identical pin numbering but different physical dimensions and thermal characteristics, while the standard BAV99 uses SOT23. Pin functions match (1 = D1 anode, 2 = D2 cathode, 3 = common), but PCB footprints and soldering profiles differ.
Does the BAV99W meet automotive reliability standards?
Yes - the BAV99W is fully qualified to AEC-Q101, covering stress tests including high-temperature reverse bias, temperature cycling, and ESD (HBM ≥8 kV). This certification applies to the full BAV99W family, including part number BAV99W/DG/B3,115.
How does the 1.5 pF capacitance impact high-speed signal lines?
At 1.5 pF, the BAV99W introduces negligible capacitive loading on signals up to 500 MHz - preserving rise/fall times and eye opening in USB 2.0, CAN FD, and SPI interfaces. Measured Cd remains stable below 2 pF across 0–80 V reverse bias, ensuring consistent performance.
