Product details
Overview
BAV99W/ZLX 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 snubbers and USB port polarity protection circuits.
For engineers reviewing the BAV99W/ZLX datasheet, BAV99W/ZLX pinout, BAV99W/ZLX application, or BAV99W/ZLX equivalent, key selection criteria include verified dual-diode topology, sub-4 ns trr at IF = 10 mA/IR = 10 mA, 1.5 pF capacitance at 0 V, 100 V VR rating, and SC-70 thermal resistance Rth(j-a) = 625 K/W on FR4 PCB.
Technical Context
The BAV99W/ZLX integrates two discrete silicon planar epitaxial switching diodes in a single SC-70 package with shared terminal (pin 3 = K1/A2), forming a common-cathode/anode configuration ideal for dual-rail clamping or complementary signal steering. Its low Cd and fast trr stem from optimized doping profiles and minimized junction area.
This device operates within −65 °C to +150 °C ambient range, supports 150 mA continuous forward current per diode, and maintains IR ≤ 0.5 µA at VR = 80 V and 25 °C - critical for low-leakage bias networks and precision sample-and-hold hold-phase isolation.
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 against transients |
| Reverse Recovery Time (trr) | ≤ 4 ns - enables reliable operation in >100 MHz switching nodes without tail current-induced shoot-through |
| Diode Capacitance (Cd) | ≤ 1.5 pF at 0 V - minimizes signal loading in RF detector and high-frequency logic clamp applications |
| Forward Voltage (VF) | 855 mV at IF = 10 mA - ensures low conduction loss in low-power level-shifting and ESD-triggered crowbar circuits |
| Reverse Current (IR) | ≤ 0.5 µA at VR = 80 V, 25 °C - preserves battery life in always-on reverse-polarity protection for portable devices |
| Thermal Resistance (Rth(j-a)) | 625 K/W - defines maximum power dissipation (200 mW at Tamb ≤ 25 °C) on standard FR4 PCB |
Pinout & Package
Package: SOT323 (SC-70), 3-terminal surface-mount plastic package measuring 2.0 mm × 1.25 mm × 0.95 mm with 1.3 mm lead pitch and tin-plated terminations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 (A1) | Input node for first diode path; connects to positive side of protected circuit or signal source |
| 2 | Cathode of Diode 2 (K2) | Output node for second diode path; routes clamped or steered signal to load or reference |
| 3 | Cathode of Diode 1 / Anode of Diode 2 (K1, A2) | Shared terminal enabling dual-diode configurations - used as common return or bidirectional clamp point |
Key Features
| Feature | Design Value |
|---|---|
| Dual-diode integration | Two independent switching diodes in one SC-70 footprint - reduces board area by 40 % vs. discrete SOD-323 pair |
| Sub-4 ns trr performance | Verified at IF = 10 mA, IR = 10 mA, RL = 100 Ω - eliminates switching noise in 50–100 MHz clock distribution paths |
| Low 1.5 pF junction capacitance | Measured at VR = 0 V, f = 1 MHz - preserves signal integrity in high-speed data line clamping (e.g., USB 2.0 D+/D−) |
| 100 V reverse blocking | Rated per diode - supports industrial 24 V and telecom 48 V systems with margin for surge events |
| 150 °C junction temperature rating | Enables operation in sealed enclosures or near heat sources without derating below 130 mA per diode |
Applications
| USB Port Polarity Protection | DC-DC Converter Snubber |
|---|---|
Use Scenario: Preventing damage from reversed VBUS connection in Type-A or micro-B USB ports. IC Role / Device Role / Timing Role: Dual-diode configured as back-to-back anode-cathode pair (pins 1–3–2) to block reverse current while passing forward current. Use Value: Delivers <0.5 µA leakage at 5 V reverse bias, eliminating standby power drain and enabling Class 3 USB compliance. |
Use Scenario: Suppressing voltage spikes across MOSFETs in synchronous buck converters operating at 500 kHz–2 MHz. IC Role / Device Role / Timing Role: Fast-recovery clamp diode placed across high-side switch to absorb inductive kickback. Use Value: 4 ns trr limits ring duration to <10 ns, reducing EMI emissions by ≥8 dBµV in 30–100 MHz band. |
| High-Speed Logic Level Shifting | RF Signal Detector Clamping |
Use Scenario: Translating 3.3 V logic signals to 5 V domains in FPGA I/O banks with tight timing budgets. IC Role / Device Role / Timing Role: Bidirectional clamping diode (pin 3 as common) limiting voltage excursions beyond supply rails. Use Value: 1.5 pF capacitance adds <0.5 ps of delay skew, preserving setup/hold margins in >100 MHz interfaces. |
Use Scenario: Protecting ADC inputs in 2.4 GHz ISM-band receiver front-ends from antenna-coupled RF overload. IC Role / Device Role / Timing Role: Low-Cd shunt diode (anode grounded, cathode to signal line) clipping RF peaks before mixer stage. Use Value: 1.5 pF capacitance yields <0.1 dB insertion loss at 2.4 GHz, maintaining receiver NF within 0.3 dB spec. |
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 (same), Cd = 2.0 pF (0.5 pF higher), VF = 875 mV at 10 mA (20 mV higher) | Slightly higher capacitance degrades RF clamping above 1 GHz; otherwise functionally interchangeable in USB and DC-DC roles | Select when sourcing from ON Semi's distribution network; verify layout clearance for 2.0 pF impact on 5+ Gbps signal lines |
| MMBD7000LT1G (ON Semiconductor) | trr = 3 ns (faster), Cd = 2.5 pF (1.0 pF higher), VR = 70 V (30 V lower) | Not suitable for 48 V telecom or 80 V transient-tolerant designs; preferred only where ultra-fast trr dominates over voltage margin | Choose only for sub-30 V systems requiring <3.5 ns trr; avoid in industrial 24 V+ applications due to VR derating |
Compared with BAV99W/ZLX, BAV99LT1G trades 0.5 pF higher capacitance for identical trr and broader global availability, while MMBD7000LT1G sacrifices 30 V VR headroom to gain 1 ns trr reduction - making BAV99W/ZLX the optimal balance for 24–48 V, 100 MHz–1 GHz mixed-signal protection.

FAQ
What is the exact pin configuration of BAV99W/ZLX?
BAV99W/ZLX uses a 3-pin SOT323 package with pin 1 = anode of diode 1 (A1), pin 2 = cathode of diode 2 (K2), and pin 3 = shared cathode of diode 1 and anode of diode 2 (K1/A2). This configuration enables back-to-back, series, or common-terminal dual-diode topologies without external wiring.
Can BAV99W/ZLX replace a single discrete diode in a design?
Yes - either diode can be used independently by connecting only pins 1 and 3 (D1) or pins 2 and 3 (D2); the unused terminal remains unconnected. Each diode meets full specifications: VR = 100 V, trr ≤ 4 ns, and IF = 150 mA continuous, with no performance penalty versus dedicated single-diode packages.
Is BAV99W/ZLX qualified for automotive applications?
No - the BAV99W/ZLX is explicitly marked non-automotive qualified in its revision history (v.9, July 2022). For automotive use, Nexperia offers the BAV99W-Q variant, which undergoes AEC-Q101 stress testing and includes extended temperature validation and PPAP documentation.
What is the maximum allowable soldering temperature profile for BAV99W/ZLX?
BAV99W/ZLX complies with JEDEC J-STD-020D reflow guidelines for MSLE Level 1. Peak reflow temperature must not exceed 260 °C for ≤ 30 seconds, with ramp-up rate ≤ 3 °C/s and ramp-down rate ≤ 6 °C/s. Wave soldering requires preheating to 100–150 °C and contact time ≤ 5 seconds at 260 °C max.
