Product details
Overview
BAV70-QR from Nexperia is a high-speed switching double diode in SOT23 package, featuring common-cathode dual-anode configuration, 100 V reverse voltage rating, ≤4 ns reverse recovery time, and ≤1.5 pF junction capacitance - deployed in automotive signal routing and ESD-protected I/O interface circuits.
For engineers reviewing the BAV70-QR datasheet, BAV70-QR pinout, BAV70-QR application, or BAV70-QR equivalent, this page delivers verified electrical parameters, validated AEC-Q101 qualification status, thermal resistance (500 K/W), forward voltage at 10 mA (855 mV), and real-world switching performance data for automotive-grade discrete selection.
Technical Context
The BAV70-QR integrates two independent high-speed silicon switching diodes sharing a common cathode terminal, enabling compact dual-path clamping or steering in space-constrained PCB layouts. Its design targets fast transient response with low stored charge, supported by trr ≤ 4 ns under IF = IR = 10 mA test conditions.
Qualified per AEC-Q101, it operates across −65 °C to +150 °C ambient and junction temperatures, with thermal resistance Rth(j-a) = 500 K/W on FR4 PCB - confirming suitability for under-hood automotive modules where thermal margin and reliability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 100 V - supports 24 V automotive bus transients and 48 V mild-hybrid system clamping without breakdown. |
| Reverse Recovery Time (trr) | ≤4 ns - enables clean switching up to ~100 MHz in RF detector or high-frequency logic clamp applications. |
| Junction Capacitance (Cd) | ≤1.5 pF at 0 V - minimizes signal loading in high-impedance analog sensing paths and high-speed data lines. |
| Forward Voltage (VF) | 855 mV at 10 mA - ensures low conduction loss in bias networks and level-shifting circuits with minimal self-heating. |
| Reverse Leakage (IR) | ≤0.5 µA at VR = 80 V, 25 °C - maintains signal integrity in precision reference or sensor front-end protection stages. |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - defines maximum continuous DC or pulsed power handling on standard FR4 layout. |
Pinout & Package
Encapsulated in SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body, optimized for automated placement and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Anode of Diode 1 | Independent input path for first signal channel; enables dual-rail clamping or OR-ing with shared cathode return. |
| 2 (A2) | Anode of Diode 2 | Second independent input node - allows bidirectional signal isolation or redundant protection on parallel I/O lines. |
| 3 (CC) | Common Cathode | Single low-inductance output node tied to ground or supply rail; reduces PCB trace count and parasitic inductance. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood use with full temperature cycling, humidity, and mechanical shock testing. |
| Low trr ≤ 4 ns | Enables accurate pulse detection and fast edge preservation in CAN FD pre-driver protection and LIN bus receivers. |
| Low Cd ≤ 1.5 pF | Preserves bandwidth in 50 Ω RF signal paths and avoids phase shift in high-frequency clock distribution networks. |
| Common-cathode dual-diode | Reduces component count and board area vs. two discrete SOT23 diodes - critical for ADAS camera module PCBs. |
Applications
| Automotive LIN Bus Protection | USB 2.0 Data Line Clamping |
|---|---|
Use Scenario: Protecting LIN transceiver I/O pins against load-dump transients and ESD events in body control modules. IC Role / Device Role / Timing Role: Dual-anode clamping diode with common cathode tied to 12 V rail, limiting voltage spikes to safe levels during battery disconnect events. Use Value: Prevents LIN transceiver latch-up or damage while maintaining <10 ns response time and <1.5 pF signal loading on 19.2 kbps bus. |
Use Scenario: ESD suppression on D+ and D− lines of USB 2.0 host ports in infotainment head units. IC Role / Device Role / Timing Role: High-speed steering diode pair directing ESD current to VBUS and GND rails before IC-level protection activates. Use Value: Achieves IEC 61000-4-2 Level 4 (±15 kV air) compliance without degrading 480 Mbps data eye integrity due to low capacitance. |
| High-Frequency RF Detector Input | Microcontroller GPIO Protection |
Use Scenario: Signal rectification and envelope detection in 2.4 GHz ISM-band receiver front-ends for keyless entry systems. IC Role / Device Role / Timing Role: Fast-switching detector diode pair converting RF bursts into baseband pulses with minimal harmonic distortion. Use Value: Delivers usable output with ≤4 ns trr and sub-pF capacitance - preserving rise time and amplitude fidelity of short RF packets. |
Use Scenario: Overvoltage and reverse-polarity protection on MCU reset, wake-up, and debug pins exposed to external connectors. IC Role / Device Role / Timing Role: Bidirectional clamping device limiting pin voltage to VDD + 0.85 V and GND − 0.3 V during hot-plug or miswiring events. Use Value: Prevents CMOS gate oxide rupture and latch-up with <0.5 µA leakage at 80 V - ensuring long-term MCU reliability in field-deployed units. |
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 |
|---|---|---|---|
| BAV99-Q | Same SOT23 package, but higher VF (1.25 V at 150 mA) and higher trr (6 ns); identical VR (100 V) and Cd (1.5 pF). | Less suitable for low-power sensor interfaces due to higher forward drop; preferred in higher-current clamp circuits. | Select BAV99-Q only when higher surge current capability (IFSM = 4 A) outweighs speed and efficiency trade-offs. |
| MMBD7000LT1G | Lower VR (70 V), same trr (4 ns), slightly higher Cd (2.0 pF), not AEC-Q101 qualified. | Limited to non-automotive industrial or consumer applications; unsuitable for 24 V/48 V automotive bus environments. | Choose MMBD7000LT1G only for cost-sensitive non-automotive designs where 70 V VR and no AEC qualification are acceptable. |
Compared with BAV99-Q and MMBD7000LT1G, the BAV70-QR uniquely balances AEC-Q101 compliance, 100 V VR, 4 ns trr, and 1.5 pF Cd - making it the only option qualified for automotive signal integrity-critical roles like LIN, USB, and RF detection where both speed and reliability are mandatory.

FAQ
Is BAV70-QR pin-compatible with BAV99?
Yes - BAV70-QR and BAV99 share identical SOT23 pinout: Pin 1 = A1, Pin 2 = A2, Pin 3 = CC. Both support common-cathode dual-diode operation, enabling direct replacement in existing layouts where VR and trr requirements align.
What is the maximum junction temperature for continuous operation?
The BAV70-QR has a rated maximum junction temperature (Tj) of 150 °C. Continuous operation at this limit requires derating Ptot per thermal resistance (500 K/W) and ambient conditions - full derating curves are provided in Figure 2 of the official Nexperia datasheet.
Does BAV70-QR support wave soldering?
Yes - Nexperia provides dedicated wave soldering footprint dimensions (Figure 9) and process guidelines. The SOT23 package is qualified for wave soldering with recommended transport direction and solder mask layout to ensure void-free joints and mechanical reliability.
How does AEC-Q101 qualification impact BAV70-QR's use in industrial applications?
AEC-Q101 qualification exceeds standard industrial reliability requirements: it includes extended temperature cycling (−65 °C to +150 °C), high-acceleration mechanical shock, and rigorous HTRB testing - providing proven robustness for mission-critical industrial controls even outside automotive contexts.
