Product details
Overview
BAV99/DG/B3,215 from Nexperia is a dual high-speed switching diode in SOT23 (TO-236AB) package, configured as two series-connected diodes sharing a common terminal (anode of D1, cathode of D2). It delivers trr ≤ 4 ns reverse recovery time, Cd ≤ 1.5 pF capacitance at 1 MHz, and VR = 100 V, enabling fast signal routing and polarity protection in compact DC/DC converter feedback paths and USB port ESD clamp circuits.
For engineers reviewing the BAV99/DG/B3,215 datasheet, BAV99/DG/B3,215 pinout, BAV99/DG/B3,215 application, or BAV99/DG/B3,215 equivalent, key selection criteria include verified dual-diode series topology, AEC-Q101 qualification for automotive use, thermal resistance Rth(j-a) = 500 K/W, and 215 mA forward current rating under standard PCB mounting conditions.
Technical Context
The BAV99/DG/B3,215 implements a dual-series diode configuration: Pin 1 is anode of Diode 1, Pin 2 is cathode of Diode 2, and Pin 3 serves as shared cathode (D1) / anode (D2). This topology supports bidirectional clamping and voltage-level translation without external node connection.
Its 4 ns trr and 1.5 pF Cd are measured under standardized conditions (IF = 10 mA → IR = 10 mA, RL = 100 Ω, f = 1 MHz, VR = 0 V), ensuring consistent high-frequency switching performance across production lots and temperature ranges up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse voltage (VR) | 100 V - supports input rail protection in 24 V industrial systems and 48 V telecom supplies |
| Reverse recovery time (trr) | ≤ 4 ns - enables operation above 100 MHz in RF detector and high-side switch snubber circuits |
| Diode capacitance (Cd) | ≤ 1.5 pF at 1 MHz, VR = 0 V - minimizes signal loading in 5 Gbps USB 3.2 Gen 2 data line clamping |
| Forward current (IF) | 215 mA continuous - sustains peak current in PWM-driven LED backlight boost converters |
| Thermal resistance (Rth(j-a)) | 500 K/W - requires minimal copper area on FR4 PCB for thermal management in space-constrained modules |
| Junction temperature (Tj) | 150 °C maximum - qualified for under-hood automotive applications per AEC-Q101 stress testing |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package with 3 leads; 2.8 mm × 1.4 mm footprint, 1.1 mm height; optimized for reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 | Input node for forward conduction path D1; connects to supply or signal source requiring clamping |
| 2 | Cathode of Diode 2 | Output node for forward conduction path D2; ties to load or reference rail |
| 3 | Shared terminal (cathode of D1, anode of D2) | Internal interconnection point enabling series diode operation; no external connection required |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive powertrain and body electronics per stress test requirements including HTGB, HTRB, and temperature cycling |
| Dual-series diode topology | Enables single-package implementation of bidirectional voltage clamping without discrete interconnects or layout parasitics |
| Low leakage current | IR ≤ 0.5 μA at VR = 80 V ensures <10 nW standby power loss in battery-backed real-time clock backup circuits |
| Small SMD footprint | SOT23 package reduces board area by 65% vs. SO-8 equivalents, critical for portable medical sensor modules |
| High-speed switching | trr ≤ 4 ns allows clean edge preservation in 100 Mbps CAN FD bus termination networks |
Applications
| USB 3.2 Data Line Protection | Automotive LIN Bus Transceiver Clamp |
|---|---|
|

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,115 | SOT323 package (smaller footprint); IF = 150 mA; Rth(j-a) = 625 K/W | Better suited for ultra-compact wearables where board area <1.5 mm² is critical | Select when thermal budget allows higher junction rise and space constraints dominate |
| BAV99S,115 | SOT363 package; quadruple configuration (4 diodes); IF = 200 mA per diode | Supports dual-channel clamping in space-constrained RS-485 transceivers | Choose when needing two independent dual-diode pairs in one package for full-duplex interface protection |
Compared with BAV99/DG/B3,215, the BAV99W offers 30% smaller footprint but sacrifices 30% forward current and thermal performance; the BAV99S provides double the functional density but requires larger PCB area and different routing topology.

FAQ
What is the exact pin configuration for BAV99/DG/B3,215?
BAV99/DG/B3,215 uses SOT23 package with Pin 1 = anode of Diode 1, Pin 2 = cathode of Diode 2, and Pin 3 = shared cathode (D1)/anode (D2). This dual-series topology is confirmed in Nexperia's official pinning diagram (Figure 7, Rev. 8 datasheet) and validated via marking code A7* on top-side laser etch.
Is BAV99/DG/B3,215 qualified for automotive applications?
Yes - BAV99/DG/B3,215 is fully AEC-Q101 qualified per Nexperia's Product data sheet Rev. 8, having passed HTGB, HTRB, and temperature cycling tests. Its 150 °C max junction temperature and 100 V VR rating meet requirements for engine control unit (ECU) power supply clamping and body electronics.
How does its 4 ns trr impact high-frequency circuit design?
A 4 ns trr enables reliable operation up to 100 MHz in switching applications, verified under IF = 10 mA → IR = 10 mA, RL = 100 Ω test conditions. This allows use in 5 Gbps USB 3.2 Gen 2 receiver clamps and 40 MHz CAN FD bus terminators without introducing measurable timing skew or overshoot.
Can BAV99/DG/B3,215 replace single-diode packages like 1N4148 in existing designs?
No - BAV99/DG/B3,215 is a dual-series diode with three terminals and internal interconnection; it cannot substitute for a single-diode 1N4148 without redesigning the schematic and layout. Its function is clamping/isolation in bidirectional signal paths, not general-purpose rectification.
