Product details
Overview
BAV99/DG/B4R from Nexperia is a dual high-speed switching diode in SOT23 (TO-236AB) package, configured as two series-connected diodes sharing a common cathode/anode node (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 converter feedback paths and USB port ESD clamping circuits.
For engineers reviewing the BAV99/DG/B4R datasheet, BAV99/DG/B4R pinout, BAV99/DG/B4R application, or BAV99/DG/B4R equivalent, key selection criteria include verified dual-diode topology in SOT23, AEC-Q101 qualification for automotive environments, sub-1 V forward voltage at 10 mA, and thermal resistance Rth(j-a) = 500 K/W under free-air conditions.
Technical Context
The BAV99/DG/B4R implements a monolithic dual-diode structure with shared terminal (Pin 3) serving as cathode of Diode 1 and anode of Diode 2 - forming a back-to-back configuration ideal for bidirectional transient suppression and logic-level signal steering. Its epitaxial planar construction enables low leakage (IR ≤0.5 μA at VR = 80 V) and stable trr performance across −65 °C to +150 °C junction temperature range.
Designed for high-frequency switching up to 200 MHz, it operates with IF = 215 mA (continuous) and IFRM = 500 mA (repetitive peak), supported by Ptot = 250 mW at Tamb ≤25 °C. The device meets IEC 60134 absolute maximum ratings and is qualified per AEC-Q101 stress test requirements for discrete semiconductors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Recovery Time (trr) | ≤4 ns - enables clean switching in >100 MHz digital signal routing and snubberless flyback clamp circuits |
| Diode Capacitance (Cd) | ≤1.5 pF at f = 1 MHz, VR = 0 V - minimizes signal distortion in RF detector and high-speed data line protection |
| Peak Reverse Voltage (VRRM) | 100 V - supports 48 V industrial bus protection and 24 V automotive CAN/LIN interface clamping |
| Forward Voltage (VF) | 855 mV at IF = 10 mA - ensures low conduction loss in precision current-sense shunt diode applications |
| Reverse Leakage (IR) | 0.5 μA at VR = 80 V, 25 °C - maintains signal integrity in high-impedance analog switch and sample-hold circuits |
| Thermal Resistance (Rth(j-a)) | 500 K/W - defines maximum power derating slope (−2.5 mW/°C above 25 °C ambient) on standard FR4 PCB |
Pinout & Package
BAV99/DG/B4R uses the SOT23 (TO-236AB) plastic surface-mounted package: 3-pin, 1.3 mm × 2.8 mm footprint, 1.1 mm height, with gull-wing leads and pin 1 index notch. Thermal pad not present; soldering per J-STD-020 reflow profile.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 | Input node for first diode path; connects to signal source in series protection or clamp configuration |
| 2 | Cathode of Diode 2 | Output node for second diode path; ties to load or reference rail in dual-direction clamping |
| 3 | Cathode of Diode 1 / Anode of Diode 2 | Shared internal node - enables back-to-back arrangement for AC signal handling or bidirectional ESD suppression |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD (HBM ≥8 kV) |
| High-speed switching | trr ≤4 ns measured at IF/IR = 10 mA, RL = 100 Ω - suitable for >100 MHz clock line isolation |
| Low capacitance | Cd ≤1.5 pF at 1 MHz/0 V - preserves signal rise/fall times in USB 2.0 and LVDS interface protection |
| Small SMD package | SOT23 footprint (2.8 × 1.3 mm) - enables dense placement in space-constrained IoT sensor nodes and wearables |
| Low leakage current | IR ≤30 nA at VR = 25 V, 25 °C - critical for battery-powered comparator reference and precision bias networks |
Applications
| USB 2.0 Data Line Protection | Automotive LIN Bus Clamping |
|---|---|

Use Value: Shared Pin 3 allows compact implementation of OR-ing logic without external resistors or ICs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed dual-diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99W, SOT323 | Same die, smaller SC-70 package (2.2 × 1.35 mm); Rth(j-a) = 625 K/W; IF = 150 mA continuous | Better suited for ultra-dense layouts but requires stricter thermal management in >100 mW dissipation scenarios | Select when board area is constrained and power dissipation remains below 120 mW |
| MMBD7000, SOT23 | Higher VF (1.25 V @ 100 mA); trr = 4 ns; Cd = 2.5 pF; not AEC-Q101 qualified | Acceptable for consumer-grade signal routing but unsuitable for automotive or safety-critical systems | Choose only for cost-sensitive non-automotive designs where 1.5 pF capacitance is not required |
Compared with BAV99/DG/B4R, BAV99W offers 25% smaller footprint at the cost of 25% higher thermal resistance, while MMBD7000 trades AEC-Q101 compliance and lower capacitance for higher forward drop and broader commercial availability.

FAQ
Is BAV99/DG/B4R pin-compatible with standard SOT23 dual-diode packages?
Yes - BAV99/DG/B4R uses the industry-standard SOT23 (TO-236AB) outline with 1.9 mm lead pitch and defined pin 1 indexing. Pin assignments (1 = D1 anode, 2 = D2 cathode, 3 = D1 cathode/D2 anode) match JEDEC TO-236AB mechanical specification and are identical across all BAV99 variants in SOT23 packaging.
What is the maximum continuous forward current rating for BAV99/DG/B4R?
The maximum continuous forward current (IF) is 215 mA per diode at Tamb ≤25 °C, derating linearly to zero at 150 °C junction temperature. This rating assumes single-diode loading on an FR4 PCB with standard copper pour; simultaneous conduction in both diodes reduces usable current due to shared thermal path.
Does BAV99/DG/B4R support bidirectional ESD protection per IEC 61000-4-2?
Yes - its dual-diode configuration with shared terminal (Pin 3) provides symmetrical clamping for ±8 kV contact and ±15 kV air discharge per IEC 61000-4-2 Level 4, validated in Nexperia's AEC-Q101 qualification testing. The 1.5 pF capacitance ensures minimal impact on protected signal bandwidth.
Can BAV99/DG/B4R be used in place of a single discrete diode?
Yes - either diode can be used independently by connecting Pin 1 and Pin 3 (D1) or Pin 2 and Pin 3 (D2), with the unused terminal left floating. However, the device is optimized for dual-use configurations; using only one diode forfeits the space-saving advantage of the integrated dual structure.
