Product details
Overview
BAV99S,115 from Nexperia is a quadruple high-speed switching diode array in SOT363 (SC-88) package, configured as two independent series-connected diode pairs (D1–D2 and D3–D4), with reverse recovery time ≤4 ns, capacitance ≤1.5 pF, and 100 V peak reverse voltage - used for ESD protection, signal clamping, and polarity reversal circuits in automotive infotainment power rails.
For engineers reviewing the BAV99S,115 datasheet, BAV99S,115 pinout, BAV99S,115 application, or BAV99S,115 equivalent, key selection criteria include verified trr ≤4 ns at IF=10 mA/IR=10 mA, dual-series topology enabling compact bidirectional clamping, AEC-Q101 qualification for under-hood use, and thermal resistance Rth(j-sp) = 260 K/W on FR4 PCB.
Technical Context
The BAV99S implements four discrete silicon planar epitaxial diodes in a single 6-pin SOT363 package, arranged as two isolated series pairs sharing common terminals (pins 3 and 6 serve as interconnect nodes). Each diode operates independently with identical electrical characteristics per datasheet Rev. 8.
Its architecture supports dual-channel bidirectional clamping without external routing: pins 1–2 form one series path (D1 anode → D2 cathode), while pins 4–5 form the second (D3 anode → D4 cathode), with shared cathode/anode junctions at pins 3 and 6 enabling compact layout in space-constrained automotive sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Recovery Time (trr) | ≤4 ns - enables clean switching up to ~100 MHz in RF detector and high-speed data line protection. |
| Diode Capacitance (Cd) | ≤1.5 pF at 1 MHz, VR = 0 V - minimizes signal distortion in 50 Ω high-frequency paths like USB 2.0 or CAN FD stubs. |
| Peak Reverse Voltage (VRRM) | 100 V - supports 24 V automotive systems with ≥2× safety margin against load dump transients. |
| Forward Current (IF) | 200 mA continuous per diode - sufficient for LED biasing, logic-level translation, and low-power rail clamping. |
| Reverse Leakage (IR) | ≤0.5 μA at VR = 80 V - ensures minimal standby current in always-on battery monitoring circuits. |
| Junction Temperature (Tj) | 150 °C maximum - validated for under-hood operation in engine control modules and ADAS camera power supplies. |
Pinout & Package
BAV99S,115 is housed in a 6-lead SOT363 (JEDEC SC-88, JEITA SC-88) surface-mount plastic package measuring 2.2 mm × 1.35 mm × 0.95 mm, optimized for automated placement and reflow soldering on dense PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 | Input node for first series diode pair; connects to protected signal source in clamp configuration. |
| 2 | Cathode of Diode 2 | Output node of first series pair; ties to reference rail (e.g., VCC or GND) for unidirectional clamping. |
| 3 | Cathode of Diode 1 / Anode of Diode 2 | Internal series junction - enables compact dual-diode path without external trace routing. |
| 4 | Anode of Diode 3 | Input node for second independent series pair; supports redundant or differential signal protection. |
| 5 | Cathode of Diode 4 | Output node of second series pair; allows separate clamping to alternate reference (e.g., VIO or AVSS). |
| 6 | Cathode of Diode 3 / Anode of Diode 4 | Internal series junction for second pair - provides symmetrical layout symmetry and thermal balance. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity testing, and mechanical shock per AEC standard. |
| Quadruple dual-series topology | Two independent 2-diode series strings enable bidirectional clamping in one footprint - reduces board area by 60% vs discrete solutions. |
| Low thermal resistance | Rth(j-sp) = 260 K/W - maintains junction temperature <125 °C at 200 mA continuous load on standard FR4, supporting high-density layouts. |
| High-speed switching | trr ≤4 ns with 100 Ω load - meets timing requirements for USB 2.0 ESD protection and LVDS receiver input conditioning. |
Applications
| Automotive Sensor Interface | USB 2.0 Data Line Protection |
|---|---|

Use Value: 4 ns trr responds before PWM controller reacts; 150 °C Tj rating aligns with transformer hotspot temperatures in enclosed enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99W,115 | SOT323 (3-pin) dual-diode variant; same trr ≤4 ns and VRRM = 100 V but only two diodes in series. | Lacks quadruple topology - unsuitable for dual-channel or differential protection requiring independent paths. | Select when board space permits larger pitch (2.2 mm vs 1.35 mm width) and only one clamping path is needed. |
| ESDR0502N | TVS diode array with 5.5 V working voltage, 12 V clamping, and 300 W peak pulse power - not a switching diode. | Designed for ESD-only suppression (IEC 61000-4-2), not continuous forward conduction or signal rectification. | Choose only for pure ESD compliance; cannot replace BAV99S,115 in active clamping or polarity protection roles. |
Compared with BAV99W,115, the BAV99S,115 delivers dual-path redundancy in half the PCB area; versus ESDR0502N, it provides controlled forward conduction and sub-ns switching essential for analog signal conditioning - not just transient suppression.

FAQ
What is the maximum continuous forward current per diode in the BAV99S,115?
The BAV99S,115 supports 200 mA continuous forward current per diode at Tamb ≤85 °C, as specified in Table 6 of the Rev. 8 datasheet. This rating applies individually to each of the four diodes and assumes standard FR4 PCB mounting with tin-plated copper layers.
Is the BAV99S,115 suitable for bidirectional signal clamping?
Yes - its internal configuration (two independent series diode pairs) enables true bidirectional clamping: pins 1–2–3 form one path, pins 4–6–5 form the other, allowing simultaneous positive and negative voltage limiting on differential or complementary signals without external components.
Does the BAV99S,115 require derating at elevated ambient temperatures?
Yes - the total power dissipation is rated at 250 mW only when solder point temperature (Tsp) is ≤85 °C. Above that, linear derating applies per the thermal resistance Rth(j-sp) = 260 K/W; at 105 °C Tsp, maximum dissipation drops to ~175 mW per device.
How does the marking code 'K1*' identify the BAV99S,115 on the package?
The top-side marking 'K1*' (where * is a manufacturing site code) is the standardized Nexperia identifier for BAV99S devices per Table 5. It appears on the SOT363 body adjacent to pin 1 index, and is verified under 20× magnification during incoming inspection per JESD22-A111.
