Product details
Overview
BAV99S/APGF 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 common cathode/anode node at pin 3 and pin 6. It delivers trr ≤4 ns reverse recovery time, Cd ≤1.5 pF capacitance, and VR = 100 V, enabling use in ESD-protected signal routing and compact DC-DC flyback snubbing circuits.
For engineers reviewing the BAV99S/APGF datasheet, BAV99S/APGF pinout, BAV99S/APGF application, or BAV99S/APGF equivalent, key selection criteria include verified dual-series diode topology, AEC-Q101 qualification for automotive environments, low-leakage performance at 80 V reverse bias (IR ≤0.5 μA), and thermal resistance Rth(j-sp) = 260 K/W under standard FR4 mounting.
Technical Context
The BAV99S implements four discrete silicon planar epitaxial diodes in a single 6-pin SOT363 package, arranged as two independent series strings: pins 1–2–3 form D1 (anode–cathode) + D2 (cathode–anode), while pins 4–5–6 form D3 + D4 with identical polarity orientation. This configuration supports bidirectional clamping and dual-rail protection without external interconnects.
Its fast switching is enabled by optimized carrier lifetime control, yielding trr ≤4 ns at IF = 10 mA → IR = 10 mA with RL = 100 Ω, and VF = 855 mV at IF = 10 mA. The device operates across −65 °C to +150 °C junction temperature and sustains IFRM = 500 mA peak forward current per diode.
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 |
| Reverse recovery time (trr) | ≤4 ns - enables >100 MHz switching in RF detector and high-frequency rectifier stages |
| Diode capacitance (Cd) | ≤1.5 pF at 0 V - minimizes signal loading in 50 Ω RF paths and high-speed data lines |
| Forward voltage (VF) | 855 mV at IF = 10 mA - ensures low conduction loss in low-power logic-level clamping |
| Reverse leakage (IR) | ≤0.5 μA at VR = 80 V - maintains integrity in battery-backed backup circuits and precision analog front-ends |
| Thermal resistance (Rth(j-sp)) | 260 K/W - allows 250 mW total power dissipation with ≤65 K rise above solder point on FR4 PCB |
| AEC-Q101 qualified | Yes - certified for automotive powertrain and body electronics per stress test requirements |
Pinout & Package
BAV99S is housed in a 6-pin SOT363 (JEDEC SC-88) surface-mount plastic package measuring 2.2 mm × 1.35 mm × 0.95 mm, with gull-wing leads and pin 1 index marked by a dot or bevelled edge.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of diode 1 (D1) | Input node for first series string; connects to signal source in clamp or steering applications |
| 2 | Cathode of diode 2 (D2) | Output node of first series string; ties to protected IC input or reference rail |
| 3 | Cathode of D1 / Anode of D2 | Internal common node - enables series connection without PCB trace; critical for dual-rail isolation |
| 4 | Anode of diode 3 (D3) | Independent second series string anode; used for complementary rail or redundant path |
| 5 | Cathode of diode 4 (D4) | Second string output; supports mirrored protection or differential signal conditioning |
| 6 | Cathode of D3 / Anode of D4 | Second internal common node - provides symmetrical layout for balanced ESD response |
Key Features
| Feature | Design Value |

Applications
| Automotive CAN Transceiver Protection | USB 2.0 Data Line Clamping |
|---|---|
|
Use Scenario: Bidirectional transient suppression on CAN_H/CAN_L lines in automotive ECUs. IC Role / Device Role / Timing Role: Dual-series diode pair (D1+D2 and D3+D4) acts as low-capacitance TVS clamp referenced to VCC and GND. Use Value: 1.5 pF capacitance prevents signal distortion at 1 Mbps CAN bit rate; 100 V VR withstands load-dump transients. |
Use Scenario: ESD protection for D+ and D− pins in portable USB host devices. IC Role / Device Role / Timing Role: Each series string (pins 1–2–3 and 4–5–6) forms a low-leakage bidirectional clamp between data line and VBUS/GND. Use Value: 0.5 μA IR at 80 V ensures no DC loading on pull-up resistors; 4 ns trr avoids data eye closure during hot-plug events. |
| DC-DC Converter Flyback Snubber | Logic-Level Signal Steering |
|
Use Scenario: Passive snubbing network across primary-side MOSFET in 5–24 V isolated flyback converters. IC Role / Device Role / Timing Role: Series-connected diodes (D1+D2) absorb turn-off voltage spikes by conducting into RC network during MOSFET off-time. Use Value: 500 mA IFRM rating handles repetitive 100 ns spikes; 260 K/W Rth(j-sp) enables stable operation at 125 °C ambient. |
Use Scenario: Directional signal routing between microcontroller GPIO and multiple peripheral inputs. IC Role / Device Role / Timing Role: Diode pairs isolate conflicting drive sources while allowing OR-ing of interrupt lines with minimal forward drop. Use Value: 855 mV VF at 10 mA ensures <100 mV logic threshold shift; SOT363 pitch matches 0.5 mm QFN footprints for co-layout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed switching diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99W/SOT323 | Triple-terminal dual-diode (SOT323, 3-pin); no internal series nodes - requires external interconnect for series configuration | Limited to single-rail clamping or simple polarity protection; not suitable for dual-series ESD structures | Select when board space permits discrete routing and only one protection path is needed |
| DMN2004LKQ-7 | Single N-channel MOSFET (SOT23) with integrated gate protection diodes; not a diode array | Replaces discrete diodes only in specific gate-drive contexts; lacks independent series-string topology | Choose only for MOSFET gate protection - not a functional substitute for BAV99S's dual-series clamping |
Compared with BAV99W and DMN2004LKQ-7, the BAV99S uniquely integrates two self-contained series-diode strings in one package, eliminating PCB traces that increase parasitic inductance in high-frequency ESD paths and enabling true dual-rail bidirectional clamping without layout compromise.

FAQ
What is the maximum continuous forward current per diode in the BAV99S/APGF?
The BAV99S supports a continuous forward current (IF) of 200 mA per diode at Tamb ≤25 °C, as specified in Table 6 of the Nexperia datasheet Rev. 8. Derating applies above 25 °C ambient, with total power dissipation limited to 250 mW at Tsp ≤85 °C.
Does the BAV99S/APGF have AEC-Q101 qualification, and what tests does it cover?
Yes, the BAV99S/APGF is AEC-Q101 qualified per Section 8.1 of the datasheet. It has passed stress tests including High-Temperature Reverse Bias (HTRB), High-Temperature Gate Bias (HTGB), Temperature Cycling (TCT), and Unbiased Highly Accelerated Stress Test (UHAST), confirming suitability for automotive powertrain and body electronics.
How is the pin 3 and pin 6 functionality implemented in the BAV99S/APGF?
Pin 3 is the shared terminal between diode 1's cathode and diode 2's anode; pin 6 serves the same role for diodes 3 and 4. This internal series connection eliminates the need for external PCB traces between diodes, reducing parasitic inductance and enabling compact dual-rail ESD protection layouts.
Can the BAV99S/APGF be used as a standalone TVS diode for IEC 61000-4-2 ESD protection?
No - the BAV99S/APGF is a high-speed switching diode array, not a dedicated TVS device. While its low capacitance and fast trr support ESD *clamping* in conjunction with external RC networks or as part of a multi-stage protection scheme, it lacks the defined breakdown voltage and surge current capability (e.g., 8 kV contact discharge) of certified TVS components.
