Product details
Overview
BAV99/DG/B3,235 from Nexperia is a dual high-speed switching diode in SOT23 (TO-236AB) package, configured as two independent series-connected 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 at 1 MHz/0 V, and VR = 100 V peak reverse voltage - enabling fast signal routing and polarity protection in compact DC-DC and interface circuits.
For engineers reviewing the BAV99/DG/B3,235 datasheet, BAV99/DG/B3,235 pinout, BAV99/DG/B3,235 application, or BAV99/DG/B3,235 equivalent, this device is selected for high-frequency switching nodes where low charge storage, minimal capacitive loading, and AEC-Q101 qualification for automotive environments are required.
Technical Context
The BAV99/DG/B3,235 integrates two discrete silicon epitaxial planar diodes in a single SOT23 package with shared terminal architecture (pin 3 = cathode of D1 / anode of D2), supporting series-switching configurations without external interconnects. Its trr ≤4 ns is measured under IF = 10 mA → IR = 10 mA, RL = 100 Ω, confirming suitability for >100 MHz signal path switching.
Thermal resistance Rth(j-a) = 500 K/W (free air) and Ptot = 250 mW at Tamb ≤25 °C define its power handling in unheatsinked PCB layouts; VF = 855 mV at IF = 10 mA and IR = 0.5 μA at VR = 80 V establish forward conduction efficiency and blocking integrity across industrial temperature ranges (−65 °C to +150 °C).
Key Specifications

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,215 | SOT323 package (smaller footprint, 1.3 × 2.2 mm); Ptot = 200 mW; Rth(j-a) = 625 K/W | Better suited for space-constrained IoT sensor nodes where thermal margin allows lower power dissipation | Select when board area is critical and average power <150 mW; verify thermal derating at 85 °C ambient |
| BAV99S,215 | SOT363 package (6-pin, quadruple configuration); includes two independent dual-diode pairs | Enables dual-channel protection (e.g., RS-485 A/B lines) in same footprint; higher pin count requires more routing | Choose for multi-line interface protection where channel count justifies added complexity and cost |
Compared with BAV99/DG/B3,235, the BAV99W offers 25% smaller PCB area but sacrifices 20% power handling and thermal performance, while the BAV99S doubles channel density at the cost of layout complexity and pin count - making the SOT23 variant optimal for single-channel, thermally demanding automotive applications.

FAQ
What is the maximum continuous forward current per diode in BAV99/DG/B3,235?
The maximum continuous forward current per diode is 215 mA at Tamb ≤25 °C, derating linearly to 125 mA at higher ambient temperatures. This rating applies to each individual diode in the dual configuration and assumes operation within the specified thermal resistance limits (Rth(j-a) = 500 K/W) on standard FR4 PCBs with tin-plated copper.
Is BAV99/DG/B3,235 suitable for bidirectional ESD protection on a single signal line?
No - BAV99/DG/B3,235 is configured as two anode-cathode series diodes (D1 and D2) with a shared terminal (pin 3), forming a unidirectional current path from pin 1 to pin 2. For true bidirectional clamping, external back-to-back diode placement or a dedicated TVS array is required; this device functions as a directional clamp or series switch only.
How does the SOT23 package of BAV99/DG/B3,235 compare thermally to the SOT323 variant?
BAV99/DG/B3,235 in SOT23 has Rth(j-a) = 500 K/W and Ptot = 250 mW at Tamb ≤25 °C, whereas the SOT323-packaged BAV99W has Rth(j-a) = 625 K/W and Ptot = 200 mW. The SOT23 offers 20% better thermal performance and 25% higher power dissipation capability, making it preferable for thermally constrained automotive under-hood designs.
Does the marking code 'A7*' on BAV99/DG/B3,235 indicate RoHS compliance?
Yes - the 'A7*' top-side marking corresponds to the BAV99 type number per Nexperia's official marking table, and all BAV99 series devices manufactured after 2006 comply with RoHS Directive 2011/65/EU. The * denotes the manufacturing site code, and full compliance documentation (including substance declarations) is available via Nexperia's quality portal using the 12NC ordering code.
