Product details
Overview
BAV99S-QF from Nexperia is a high-speed dual-series-pair switching diode array in SOT363-3 (TSSOP6) package, comprising four diodes configured as two series-connected anode-cathode pairs per channel. It delivers trr ≤ 4 ns reverse recovery time, Cd ≤ 1.5 pF capacitance, and VR = 100 V, enabling use in automotive-grade ESD-protected signal routing and polarity protection circuits.
For engineers reviewing the BAV99S-QF datasheet, BAV99S-QF pinout, BAV99S-QF application, or BAV99S-QF equivalent, this device supports high-frequency signal clamping, bidirectional transient suppression, and compact dual-channel reverse polarity protection in space-constrained automotive control modules and infotainment interfaces.
Technical Context
The BAV99S-QF integrates four silicon switching diodes in a single TSSOP6 package with internal series pairing: Diodes 1 & 2 form one channel (A1–K2), and Diodes 3 & 4 form the second (A3–K4), sharing common terminals K3/A4 and K1/A2. This configuration enables dual independent high-speed switching paths with matched dynamic characteristics.
It operates across –65 °C to +150 °C ambient, supports IF = 200 mA per diode (500 mA peak), and exhibits VF = 855 mV at IF = 10 mA and IR ≤ 0.5 µA at VR = 80 V - all verified under AEC-Q101 stress qualification for automotive reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse voltage (VR) | 100 V - supports 24 V and 48 V automotive bus protection without derating. |
| Reverse recovery time (trr) | ≤ 4 ns - enables reliable operation up to ~100 MHz switching in signal path clamping. |
| Diode capacitance (Cd) | ≤ 1.5 pF at 0 V - minimizes signal distortion in RF-coupled or high-speed data lines. |
| Forward voltage (VF) | 855 mV at 10 mA - ensures low conduction loss in low-power logic-level protection circuits. |
| Reverse leakage (IR) | ≤ 0.5 µA at 80 V / 25 °C - maintains integrity in battery-backed or always-on monitoring nodes. |
| Junction temperature (Tj) | 150 °C maximum - allows sustained operation in engine bay or powertrain control units. |
| Package | SOT363-3 (TSSOP6) - 2.2 × 1.35 mm footprint with 0.65 mm pitch, compatible with standard reflow profiles. |
Pinout & Package
Encapsulated in a surface-mount TSSOP6 (SOT363-3) plastic package with 0.65 mm lead pitch and 2.2 mm × 1.35 mm body size. Pin 1 marked by index notch on transparent top view.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 (A1) | Input node for first series-switching path; connects to protected signal source. |
| 2 | Cathode of Diode 2 (K2) | Output node for first path; ties to load or downstream circuitry. |
| 3 | Cathode of Diode 3 / Anode of Diode 4 (K3;A4) | Shared terminal enabling dual-series topology; critical for bidirectional clamp symmetry. |
| 4 | Anode of Diode 3 (A3) | Input node for second series-switching path; electrically isolated from Pin 1. |
| 5 | Cathode of Diode 4 (K4) | Output node for second path; provides redundancy or differential signal handling. |
| 6 | Cathode of Diode 1 / Anode of Diode 2 (K1;A2) | Shared terminal completing first series pair; establishes common reference point. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under temperature cycling, HTRB, and ESD-HBM ≥ 2 kV - eliminates qualification overhead for Tier 1 designs. |
| Ultra-low trr (≤ 4 ns) | Enables clean edge transitions in 10–100 MHz clock/data lines without ringing or shoot-through risk. |
| Dual-series-pair architecture | Provides two independent, matched switching channels in one footprint - reduces PCB area vs. discrete dual-diode solutions. |
| Low Cd (≤ 1.5 pF) | Maintains signal integrity in USB 2.0, CAN FD, and LIN bus termination networks without added impedance mismatch. |
| High VR (100 V) | Withstands load-dump transients (ISO 7637-2 Pulse 5a) in 24 V systems without external TVS stacking. |
Applications
| Automotive Infotainment Signal Clamping | Engine Control Unit Reverse Polarity Protection |
|---|---|
Use Scenario: Protecting HDMI/MIPI D-PHY receiver inputs from ESD and overvoltage during hot-plug events in head unit designs. IC Role / Device Role / Timing Role: High-speed bidirectional clamping diode array placed at connector interface before signal conditioning ICs. Use Value: 4 ns trr and 1.5 pF Cd prevent signal degradation while meeting ISO 10605 ±8 kV contact discharge requirements. |
Use Scenario: Safeguarding 5 V sensor supply rails against accidental reverse battery connection in ECM modules. IC Role / Device Role / Timing Role: Dual-series diode pair acting as low-loss, fast-turn-off polarity guard between battery input and LDO input. Use Value: 100 V VR rating handles 24 V system transients; 0.5 µA IR ensures minimal quiescent drain during vehicle sleep mode. |
| ADAS Camera Module ESD Filtering | Body Control Module I/O Protection |
Use Scenario: Filtering ESD pulses on FPD-Link III serial video lines between camera and processor in surround-view systems. IC Role / Device Role / Timing Role: Low-capacitance series diode pair inserted inline to shunt transients without attenuating 3 Gbps video signals. Use Value: 1.5 pF Cd avoids measurable eye diagram closure; AEC-Q101 qualification ensures field reliability under vibration/thermal cycling. |
Use Scenario: Protecting LIN bus transceiver GPIO pins from induced surges in door module actuators and switches. IC Role / Device Role / Timing Role: Dual-channel clamping array tied between LIN line and ground, with series resistance for current limiting. Use Value: Matched trr and VF across both channels ensure symmetrical response to positive/negative transients per ISO 16750-2. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed dual-diode switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99W-Q | SOT323-3 (SC-70) package; same electrical specs but 2.2 × 1.35 mm → 2.1 × 1.25 mm footprint; 0.65 mm pitch retained. | Better suited for ultra-dense layouts where 0.1 mm reduction in length/width matters; slightly lower thermal mass. | Select when board real estate is constrained beyond TSSOP6 limits but same AEC-Q101 compliance and performance are required. |
| PMEG3010CEAX | Single Schottky diode, 30 V VR, 1000 mA IF, VF ≈ 390 mV - no series-pair architecture or trr specification. | Only suitable for low-voltage forward-biased rectification, not high-speed clamping or reverse polarity protection above 30 V. | Not interchangeable; choose only for low-VF DC power path applications where speed and dual-channel capability are irrelevant. |
Compared with BAV99W-Q, the BAV99S-QF offers identical electrical behavior in a marginally larger but more thermally robust TSSOP6 package; PMEG3010CEAX serves fundamentally different functions and cannot replace the BAV99S-QF in signal integrity or automotive transient protection roles.

FAQ
Is the BAV99S-QF pin-to-pin compatible with the standard BAV99S?
Yes - the BAV99S-QF uses identical TSSOP6 (SOT363-3) pinout and internal diode configuration as the non-automotive BAV99S. The '-Q' suffix denotes AEC-Q101 qualification and enhanced process controls, with no mechanical or electrical interface changes.
Can the BAV99S-QF be used in place of two separate BAV99 diodes?
No - the BAV99S-QF contains four diodes arranged as two series-connected pairs (not two independent dual-diodes). Its internal topology (shared terminals K3/A4 and K1/A2) enables dual-channel series switching but does not replicate parallel dual-BAV99 functionality.
What is the maximum continuous forward current per diode in the BAV99S-QF?
The absolute maximum continuous forward current per diode is 200 mA at Tamb ≤ 85 °C, as specified in Table 5 (Limiting values). Derating applies above 85 °C ambient; at 125 °C, max IF drops to approximately 120 mA based on thermal resistance Rth(j-sp) = 260 K/W.
Does the BAV99S-QF require special PCB layout considerations for thermal performance?
Yes - soldering points at Pins 2, 3, 5, and 6 serve as primary thermal paths. The recommended footprint (Fig. 8) specifies 0.5 mm × 0.5 mm solder lands on those pins and 0.6 mm × 0.6 mm on Pins 1 and 4. Thermal vias under Pins 2/3/5/6 are strongly advised for sustained >100 mA operation.
