Product details
Overview
BAV99-QR from Nexperia is a dual high-speed switching diode in SOT23 package, configured as two independent diodes sharing a common terminal (anode of D1 and cathode of D2), with 100 V reverse voltage rating, ≤4 ns reverse recovery time, ≤1.5 pF capacitance, and AEC-Q101 qualification for automotive use - deployed in ECU power rail protection and CAN bus transient suppression.
For engineers reviewing the BAV99-QR datasheet, BAV99-QR pinout, BAV99-QR application, or BAV99-QR equivalent, this page delivers verified electrical parameters, validated dual-diode topology, automotive-grade reliability data, thermal resistance values, and real-world switching performance metrics under defined test conditions (IF = 10 mA, IR = 10 mA, RL = 100 Ω).
Technical Context
The BAV99-QR implements a monolithic dual-diode structure in a single SOT23-3 package, with Pin 1 = anode of Diode 1, Pin 2 = cathode of Diode 2, and Pin 3 = shared cathode/anode node. Its architecture enables compact bidirectional clamping and series switching without external interconnects.
Designed for high-frequency signal path control, it delivers trr ≤ 4 ns at IF = 10 mA and IR = 10 mA, Cd ≤ 1.5 pF at VR = 0 V / f = 1 MHz, and maintains IR ≤ 0.5 µA at VR = 80 V and Tamb = 25 °C - enabling reliable operation in 1–100 MHz digital interface protection and DC-DC converter snubbing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 100 V - supports 24 V automotive systems with ≥2× safety margin against load dump transients. |
| Reverse Recovery Time (trr) | ≤4 ns - enables clean switching in >50 MHz clock lines and fast digital I/O protection. |
| Diode Capacitance (Cd) | ≤1.5 pF at 0 V - minimizes signal distortion in RF front-end and high-speed data line clamping. |
| Forward Voltage (VF) | 855 mV at IF = 10 mA - ensures low conduction loss in series polarity protection paths. |
| Reverse Current (IR) | ≤0.5 µA at VR = 80 V - guarantees stable leakage behavior across temperature in battery-sensed circuits. |
| Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - allows continuous operation in space-constrained PCB layouts with standard FR4 mounting. |
| Junction Temperature (Tj) | 150 °C maximum - enables deployment in under-hood automotive modules without derating. |
Pinout & Package
Package: SOT23 (TO-236AB), 3-terminal surface-mount plastic package, 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch, qualified per AEC-Q101.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 (A1) | Input node for forward conduction path of first diode; connects to protected signal or supply rail. |
| 2 | Cathode of Diode 2 (K2) | Output node for second diode's clamping action; ties to ground or reference plane for transient shunting. |
| 3 | Common terminal (K1/A2) | Shared node: cathode of Diode 1 and anode of Diode 2 - enables back-to-back or series-switching configurations. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and body electronics with full stress-test compliance. |
| Ultra-low trr (≤4 ns) | Enables accurate timing preservation in high-speed logic interfaces and pulse-width modulated power stages. |
| Low Cd (≤1.5 pF) | Prevents capacitive loading on USB 2.0, LVDS, and CAN FD signal lines during ESD clamp operation. |
| Thermal resistance Rth(j-a) = 500 K/W | Supports thermal design on standard FR4 PCBs without heatsinking in ambient temperatures up to +85 °C. |
| Double-diode integration | Reduces board area by 40% vs. discrete dual-diode solutions while eliminating routing skew between matched devices. |
Applications
| Automotive ECU Power Protection | CAN Bus Transient Suppression |
|---|---|

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-Q | SOT323 package (smaller footprint: 2.1 mm × 1.25 mm); identical electrical specs and AEC-Q101 qualification. | Better suited for ultra-dense layouts where board area is constrained beyond SOT23 limits. | Select when PCB real estate is prioritized over reflow process compatibility with legacy SOT23 tooling. |
| MMBD7000LT1G | Non-automotive grade; trr = 4 ns (typ), VR = 100 V, but not AEC-Q101 qualified; higher IR (1 µA @ 80 V). | Limited to industrial or consumer applications where automotive reliability certification is not required. | Choose only for cost-sensitive non-automotive designs where qualification documentation is not mandated. |
Compared with BAV99W-Q, the BAV99-QR offers identical performance in a more widely supported SOT23 footprint; versus MMBD7000LT1G, it provides certified automotive robustness, lower leakage, and guaranteed trr max specification - critical for functional safety-critical subsystems.

FAQ
What is the exact pin configuration of BAV99-QR and how is it used in back-to-back diode applications?
BAV99-QR has Pin 1 = A1 (anode of D1), Pin 2 = K2 (cathode of D2), and Pin 3 = K1/A2 (shared cathode of D1 and anode of D2). In back-to-back configuration, Pins 1 and 2 serve as the outer terminals, while Pin 3 connects to ground or reference - enabling symmetrical clamping of both positive and negative transients on differential signals like CAN or RS-485.
Does BAV99-QR meet AEC-Q101 requirements for temperature cycling and mechanical shock?
Yes - BAV99-QR is fully qualified per AEC-Q101 Rev D, including temperature cycling (−40 °C to +125 °C, 1000 cycles), mechanical shock (1500g, 0.5 ms), and highly accelerated stress test (HAST) at 130 °C/85% RH/96 h. Full qualification report documentation is available upon request for OEM release packages.
Can BAV99-QR replace single-diode SOD-323 packages in existing designs without layout changes?
No - BAV99-QR uses SOT23 (3-pin) with a specific dual-diode topology and shared terminal, whereas SOD-323 is a 2-pin single-diode package. Direct replacement requires schematic revision to accommodate the third terminal and verify functional equivalence in the target circuit topology (e.g., series switch vs. clamping).
What is the maximum allowable soldering temperature profile for BAV99-QR during reflow?
BAV99-QR complies with JEDEC J-STD-020D.3 for moisture sensitivity level 1. Peak reflow temperature must not exceed 260 °C for ≤30 seconds, with ramp-up rate ≤3 °C/s and ramp-down rate ≤6 °C/s. Recommended profile follows IPC-7531 Class 3 guidelines for SOT23 packages on FR4 boards.
