Product details
Overview
BAV99W/ZLF 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 DC-DC converter flyback snubbers and USB port polarity protection circuits.
For engineers reviewing the BAV99W/ZLF datasheet, BAV99W/ZLF pinout, BAV99W/ZLF application, or BAV99W/ZLF equivalent, this page provides verified pin functions, thermal resistance (Rth(j-a) = 625 K/W), forward voltage (VF = 855 mV @ 10 mA), reverse leakage (IR = 0.5 µA @ 80 V), and validated alternatives for high-frequency discrete switching designs.
Technical Context
The BAV99W/ZLF integrates two silicon planar epitaxial diodes in a single SC-70 package with shared terminal architecture (pin 3 = K1/A2), supporting series or parallel dual-diode configurations without external interconnects. Its low trr and Cd stem from optimized doping profiles and minimal junction area.
It operates across –65 °C to +150 °C ambient, with Ptot = 200 mW at Tamb ≤ 25 °C and Rth(j-sp) = 300 K/W to solder point - confirming suitability for thermally constrained PCB layouts with FR4 single-sided copper footprints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 100 V - supports input rail protection up to 80 V DC with 20 % margin before breakdown. |
| Reverse Recovery Time (trr) | 4 ns - enables clean switching at >100 MHz in RF detector or sampling gate applications. |
| Diode Capacitance (Cd) | 1.5 pF @ 0 V - minimizes signal coupling distortion in high-impedance analog switch nodes. |
| Forward Voltage (VF) | 855 mV @ 10 mA - ensures low conduction loss in low-current logic-level clamping paths. |
| Reverse Leakage (IR) | 0.5 µA @ 80 V, 25 °C - maintains signal integrity in high-Z bias networks over temperature. |
| Thermal Resistance (Rth(j-a)) | 625 K/W - defines maximum power derating slope (–3.2 mW/°C above 25 °C) on standard FR4. |
Pinout & Package
Package: SOT323 (SC-70), 3-terminal plastic surface-mount package measuring 2.0 mm × 1.25 mm × 0.95 mm with 1.3 mm lead pitch and standardized reflow footprint (2.65 mm × 2.35 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 (A1) | Input node for first diode's forward conduction path; connects to source in reverse polarity protection. |
| 2 | Cathode of Diode 2 (K2) | Output node for second diode's clamping action; ties to ground or reference rail in level-shifting circuits. |
| 3 | Cathode of Diode 1 / Anode of Diode 2 (K1, A2) | Shared internal node enabling compact dual-diode topologies - eliminates external trace routing between devices. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-diode integration in SC-70 | Reduces board area by >50 % vs. two discrete SOT23 diodes while maintaining isolation between anode/cathode pairs. |
| 4 ns reverse recovery time | Enables reliable operation in 50–100 MHz clocked switching nodes without tail current-induced shoot-through. |
| 1.5 pF junction capacitance | Limits capacitive loading on high-frequency signal lines (e.g., USB D+/D−, I²C bus), preserving edge integrity. |
| 100 V peak reverse voltage rating | Supports industrial 24 V and telecom 48 V supply rail protection without derating for transients. |
| 0.5 µA max reverse leakage @ 80 V | Prevents measurable current diversion in precision voltage reference or sensor bias networks at room temperature. |
Applications
| USB Port Polarity Protection | DC-DC Converter Snubber Network |
|---|---|

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) | trr = 4 ns, Cd = 2.0 pF, VR = 70 V, SOT-23 package (larger footprint) | Lower VR limits use in 48 V systems; larger SOT-23 increases board area by ~2.5× | Select when legacy SOT-23 placement exists and 70 V VR suffices. |
| PMEG3010CEH (Nexperia) | Single Schottky diode, VF = 390 mV @ 1 A, trr not specified, VR = 30 V | No dual-diode topology; unsuitable for shared-node configurations like polarity protection | Choose only for ultra-low VF requirements in single-path rectification below 30 V. |
Compared with BAV99LT1G, the BAV99W/ZLF offers 30 V higher VR and 30 % smaller footprint; versus PMEG3010CEH, it provides dual-diode functionality and defined trr - making it uniquely suited for compact, high-voltage, bidirectional switching roles.

FAQ
What is the function of pin 3 in the BAV99W/ZLF?
Pin 3 serves as the shared terminal connecting the cathode of diode 1 (K1) and the anode of diode 2 (A2). This configuration enables compact dual-diode implementations such as back-to-back protection or series-connected switching paths without external wiring, reducing parasitic inductance and PCB real estate.
Can BAV99W/ZLF replace a single discrete diode in a circuit?
Yes - either diode within the BAV99W/ZLF can be used independently by leaving the unused anode or cathode floating. For example, pins 1 and 3 form diode 1 (A1–K1), while pins 3 and 2 form diode 2 (A2–K2); the third pin remains electrically functional in either mode without performance degradation.
Is BAV99W/ZLF qualified for automotive applications?
No - per Nexperia's 2022 revision history, the BAV99W is explicitly designated as non-automotive qualified. It lacks AEC-Q101 stress testing and automotive-grade process controls. For automotive use, Nexperia recommends the BAV99W-Q variant, which undergoes full qualification per AEC-Q101 standards.
How does thermal resistance affect BAV99W/ZLF's power handling?
With Rth(j-a) = 625 K/W, the junction temperature rises 625 °C per watt dissipated under free-air conditions. At 25 °C ambient, the 200 mW absolute maximum power rating drops linearly - e.g., to 125 mW at 125 °C ambient - requiring careful layout and thermal relief if operating near Ptot limits in enclosed environments.
