Product details
Overview
BAV99/8,235 from Nexperia is a dual high-speed switching diode in SOT23 (TO-236AB) package, configured as two independent series-connected diodes sharing a common cathode/anode terminal (Pin 3). It delivers trr ≤4 ns reverse recovery time, Cd ≤1.5 pF capacitance, and VR = 100 V, enabling fast signal routing and polarity protection in compact DC-DC converters and USB interface circuits.
For engineers reviewing the BAV99/8,235 datasheet, BAV99/8,235 pinout, BAV99/8,235 application, or BAV99/8,235 equivalent, this device is selected for high-frequency switching nodes where low charge storage, minimal parasitic capacitance, and AEC-Q101 qualification for automotive-grade reliability are required.
Technical Context
The BAV99/8,235 implements a dual-series diode configuration in a single SOT23 package: Diode 1 anode at Pin 1, cathode at Pin 3; Diode 2 anode at Pin 3, cathode at Pin 2 - forming a bidirectional clamping path. Its silicon planar epitaxial construction enables consistent trr ≤4 ns under IF = 10 mA → IR = 10 mA switching with RL = 100 Ω.
Thermal performance is defined by Rth(j-a) = 500 K/W (free air) and Rth(j-sp) = 360 K/W, supporting continuous operation up to Tj = 150 °C. The device meets AEC-Q101 stress test requirements for automotive discrete semiconductors, including temperature cycling, HTRB, and ESD robustness.
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 against transients |
| Reverse recovery time (trr) | ≤4 ns - enables clean switching in >100 MHz digital signal paths and high-frequency SMPS feedback loops |
| Diode capacitance (Cd) | ≤1.5 pF at 0 V - minimizes signal loading on RF/USB 2.0 data lines and high-speed logic inputs |
| Forward current (IF) | 215 mA continuous - sufficient for LED biasing, level-shifting, and low-power signal steering |
| Reverse leakage (IR) | ≤0.5 μA at VR = 80 V - ensures low standby power loss in battery-backed polarity guard circuits |
| Junction temperature (Tj) | 150 °C max - allows operation in under-hood automotive modules and industrial controllers without derating |
Pinout & Package

| 2 | Cathode (Diode 2) | Output node for second diode; ties to ground or reference in bidirectional ESD protection paths |
| 3 | Common terminal (cathode of D1 / anode of D2) | Shared internal node enabling series diode topology - critical for dual-rail clamping and logic-level translation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and infotainment power supplies |

Applications
| USB 2.0 Data Line Protection | Automotive ECU Power Rail Clamp |
|---|---|
|
Use Scenario: Bidirectional transient suppression on USB D+ and D− lines against ESD and cable-induced surges. IC Role / Device Role / Timing Role: Dual-series diode clamps each data line to VBUS and GND using shared terminal (Pin 3) as reference node. Use Value: 1.5 pF capacitance avoids signal rise/fall time degradation; 4 ns trr prevents data corruption during hot-plug events. |
Use Scenario: Reverse-polarity and load-dump protection on 12 V power input to engine control unit (ECU) microcontroller supply rails. IC Role / Device Role / Timing Role: Series-connected diodes isolate reverse voltage while allowing forward conduction during normal operation. Use Value: 100 V VR withstands ISO 7637-2 Pulse 5a (load dump); AEC-Q101 rating ensures reliability across −40 °C to +125 °C ambient. |
| High-Frequency SMPS Feedback Isolation | LVDS Receiver Input Clamp |
|
Use Scenario: Isolating optocoupler feedback signals in isolated flyback converters operating above 500 kHz switching frequency. IC Role / Device Role / Timing Role: Fast-switching diode pair routes error amplifier output while blocking noise coupling into primary-side controller. Use Value: 4 ns trr prevents timing skew in feedback loop; 215 mA IF handles typical optocoupler LED drive currents. |
Use Scenario: Protecting LVDS receiver inputs from overvoltage and ESD in industrial camera link interfaces. IC Role / Device Role / Timing Role: Low-capacitance dual diode clamps differential inputs to common-mode range without distorting 600 Mbps data eye. Use Value: 1.5 pF Cd avoids jitter accumulation; 0.5 μA IR ensures no DC offset injection into high-impedance receiver inputs. |
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/SOT323 | Same electrical specs but SC-70 (SOT323) package: smaller footprint (1.3 × 2.2 mm), higher Rth(j-a) = 625 K/W | Better suited for space-constrained portable devices; thermal derating required above 100 mW dissipation | Select when PCB area is critical and power dissipation remains below 100 mW |
| MMBD7000LT1G | trr = 4 ns, VR = 100 V, but Cd = 2.5 pF (higher), IF = 200 mA (slightly lower), not AEC-Q101 qualified | Acceptable for commercial-grade consumer electronics; unsuitable for automotive safety-critical modules | Choose for cost-sensitive non-automotive designs where 1 pF extra capacitance is tolerable |
Compared with BAV99/8,235, the BAV99W offers superior miniaturization at the expense of thermal performance, while the MMBD7000LT1G trades automotive qualification and lower capacitance for broader commercial availability and lower unit cost.

FAQ
What is the maximum continuous forward current rating for BAV99/8,235?
The BAV99/8,235 is rated for 215 mA continuous forward current per diode at Tamb ≤25 °C, with thermal derating applied above that ambient temperature. At 85 °C ambient, the usable IF drops to approximately 125 mA due to its 500 K/W junction-to-ambient thermal resistance.
Is BAV99/8,235 suitable for USB 2.0 ESD protection?
Yes - its 1.5 pF diode capacitance preserves USB 2.0 signal integrity, and its AEC-Q101 qualification confirms robustness against IEC 61000-4-2 Level 4 (±15 kV air, ±8 kV contact) ESD pulses when implemented in standard bidirectional TVS clamp topology with appropriate series impedance.
How does the dual-series configuration affect circuit layout?
The shared terminal (Pin 3) serves as both cathode of Diode 1 and anode of Diode 2, requiring careful net assignment: Pin 1 connects to signal source, Pin 2 to reference/ground, and Pin 3 to clamping rail (e.g., VBUS or mid-rail). This eliminates need for external series connection and reduces parasitic inductance.
Does BAV99/8,235 require special PCB layout considerations for thermal performance?
Yes - its 500 K/W Rth(j-a) demands adequate copper pour on the SOT23 pad (minimum 10 mm² per lead) and thermal vias under the center pad (if present). For sustained 215 mA operation, keep ambient temperature below 55 °C or implement forced airflow; above 85 °C, derate to 125 mA.
