Product details
Overview
BAV99QB from Nexperia is a dual-series high-speed switching diode pair in a DFN1110D-3 (SOT8015) package, configured as two diodes in series with shared terminal (K1/A2), supporting reverse polarity protection and high-frequency signal routing. It delivers trr ≤ 4 ns, VR ≤ 90 V, and Cd ≤ 2 pF at 1 MHz, with 0.5 mm profile for space-constrained PCB layouts in portable power management.
For engineers reviewing the BAV99QB datasheet, BAV99QB pinout, BAV99QB application, or BAV99QB equivalent, key selection criteria include ultra-fast recovery time, low capacitance for RF-adjacent switching, side-wettable flanks for AOI-compatible reflow, and thermal resistance Rth(j-sp) = 200 K/W on standard FR4.
Technical Context
The BAV99QB integrates two discrete high-speed switching diodes in a single ultra-thin DFN package with a shared internal node (Pin 3 = K1/A2), enabling series-connected operation without external wiring. Its trr ≤ 4 ns is measured under standardized IF = 10 mA / IR = 10 mA / RL = 100 Ω conditions, confirming suitability for >100 MHz digital signal clamping and flyback snubbing.
Thermal design relies on solder-point conduction: Rth(j-sp) = 200 K/W to cathode pad and Rth(j-a) = 320 K/W to ambient on FR4, with Ptot = 390 mW per diode at Tamb ≤ 25 °C. The 0.65 mm pitch and side-wettable flanks support automated optical inspection and IPC-compliant reflow profiles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 90 V max - supports 24 V and 48 V industrial bus protection without derating |
| Reverse Recovery Time (trr) | ≤ 4 ns - enables clean switching in >100 MHz clock distribution and data line clamping |
| Diode Capacitance (Cd) | ≤ 2 pF at 0 V, 1 MHz - minimizes signal distortion in RF front-end bias networks |
| Forward Current (IF) | 300 mA per diode - sufficient for LED driver bias and logic-level translation paths |
| Leakage Current (IR) | 0.5 µA at VR = 80 V, 25 °C - ensures low standby power loss in always-on protection circuits |
| Package Height | 0.48 mm max - fits beneath 0.5 mm Z-height connectors and stacked FPC interfaces |
Pinout & Package
BAV99QB uses the DFN1110D-3 (SOT8015) leadless plastic package: 1.1 mm × 1.0 mm × 0.48 mm body, 0.65 mm pitch, side-wettable flanks, and 0.5 mm max profile. Mounting requires tin-plated FR4 with 1 cm² cathode pad for rated thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 (A1) | Input node for first diode in series chain; connects to supply or signal source |
| 2 | Cathode of Diode 2 (K2) | Output node for second diode; defines common cathode path in dual-diode configuration |
| 3 | Shared terminal: Cathode of Diode 1 (K1) and Anode of Diode 2 (A2) | Internal series junction point - eliminates external trace between diodes, reducing parasitic inductance |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | trr ≤ 4 ns enables use in 100+ MHz digital signal integrity applications without timing skew |
| Ultra-small footprint | DFN1110D-3 occupies 1.1 mm² - saves >60% board area vs. SOT23 dual-diode alternatives |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints without X-ray, improving manufacturing yield |
| Low-profile construction | 0.48 mm max height allows placement under low-clearance shields and flex-to-board interfaces |
| Low leakage & capacitance | IR ≤ 0.5 µA and Cd ≤ 2 pF maintain signal fidelity in battery-backed and RF-coupled circuits |
Applications
| USB Power Delivery Protection | High-Speed Logic-Level Translation |
|---|---|
|
Use Scenario: Bidirectional 5–20 V power path in USB-C PD controllers with reverse-current blocking. IC Role / Device Role / Timing Role: Series-connected diode pair provides polarity-insensitive input protection while maintaining <4 ns turn-off for dynamic load switching. Use Value: Eliminates need for discrete MOSFET-based ideal diodes, reducing BOM count and layout complexity in compact PD sink designs. |
Use Scenario: Level-shifting between 3.3 V microcontroller GPIOs and 5 V peripheral buses in industrial I/O modules. IC Role / Device Role / Timing Role: Dual-diode clamp network limits voltage excursions during hot-swap events without distorting 10 MHz SPI clock edges. Use Value: Cd ≤ 2 pF prevents capacitive loading-induced jitter; trr ≤ 4 ns avoids pulse-width distortion in 50 ns minimum pulse applications. |
| RF Front-End Bias Switching | Automotive Body Control Module Inputs |
|
Use Scenario: DC bias injection into 900 MHz LTE antenna switches while isolating RF path from baseband circuitry. IC Role / Device Role / Timing Role: High-isolation series diode pair blocks RF leakage during transmit mode and passes DC bias during receive mode. Use Value: VR = 90 V withstands transient surges; Cd ≤ 2 pF minimizes insertion loss (<0.1 dB) at 900 MHz. |
Use Scenario: Input protection for LIN bus receivers exposed to load-dump transients in automotive door modules. IC Role / Device Role / Timing Role: Fast-recovery dual diode clamps 12 V supply rail against ±100 V spikes while preserving <1 µs response for fault detection. Use Value: trr ≤ 4 ns ensures clamping action completes before microcontroller watchdog timeout; Rth(j-sp) = 200 K/W sustains 150 °C junction temp during 100 ms pulses. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-series high-speed switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99W,115 | SOT323 package (2.1 mm × 1.25 mm × 0.95 mm); trr ≤ 4 ns; VR = 70 V; Cd = 2 pF; no side-wettable flanks | Larger footprint and higher profile limit use in ultra-thin wearables and stacked FPC assemblies | Select when AOI capability is not required and board space permits larger SMT footprint |
| PMEG3010CEAX | Single Schottky diode, 30 V VR, 1 A IF, 0.45 V VF; SOD323 package; no series dual configuration | Cannot replicate series-connected topology; lacks shared K1/A2 terminal for integrated dual-diode function | Choose only for low-VF forward conduction where series diode architecture is unnecessary |
Compared with BAV99W,115, the BAV99QB offers 57% smaller footprint and AOI support; versus PMEG3010CEAX, it provides true dual-series functionality essential for polarity-agnostic protection and signal routing-neither alternative replicates its shared-terminal topology or 90 V rating.

FAQ
What is the maximum continuous forward current per diode in the BAV99QB?
The BAV99QB supports 300 mA continuous forward current per diode when mounted on an FR4 PCB with single-sided copper and standard footprint, as specified in Table 1. Derating begins above 25 °C ambient, reaching 175 mA when both diodes conduct simultaneously at Tamb = 25 °C.
Does the BAV99QB support automatic optical inspection (AOI) of solder joints?
Yes-the DFN1110D-3 package features side-wettable flanks that expose solder along the lateral edges of Pins 1, 2, and 3, enabling reliable AOI verification without X-ray. This is explicitly cited in Section 2 as a key benefit and confirmed in Figure 11's reflow footprint guidelines.
How is the shared terminal (Pin 3) electrically configured in the BAV99QB?
Pin 3 is internally connected to both the cathode of Diode 1 (K1) and the anode of Diode 2 (A2), forming a hard-wired series connection. This eliminates external trace inductance and enables true dual-diode series operation-distinct from back-to-back or common-cathode configurations found in other dual-diode packages.
What thermal resistance values apply to the BAV99QB under standard mounting conditions?
When mounted on FR4 with single-sided copper and standard footprint, Rth(j-a) = 320 K/W (junction-to-ambient) and Rth(j-sp) = 200 K/W (junction-to-solder-point) are specified in Table 6. These values assume tin-plated copper and validate the 390 mW per-diode power dissipation rating at Tamb ≤ 25 °C.
