Product details
Overview
BAV70W from Nexperia is a high-speed switching double diode in SOT323 (SC-70) package, featuring common-cathode configuration, 100 V reverse voltage rating, ≤4 ns reverse recovery time, and ≤1.5 pF capacitance - deployed in signal routing and clamping circuits of USB interface protection and RF front-end bias networks.
For engineers reviewing the BAV70W datasheet, BAV70W pinout, BAV70W application, or BAV70W equivalent, key selection criteria include reverse recovery speed under 10 mA test conditions, low-junction capacitance at 0 V bias, common-cathode dual-diode topology for compact bidirectional clamping, and thermal resistance of 625 K/W on FR4 PCB.
Technical Context
The BAV70W integrates two independent silicon switching diodes sharing a single cathode terminal, enabling simultaneous clamping or steering functions without cross-coupling. Its epitaxial planar construction supports fast carrier recombination, yielding trr ≤ 4 ns with IF = 10 mA and IR(meas) = 1 mA.
Designed for low-capacitance signal path integrity, it delivers Cd ≤ 1.5 pF at 0 V and 1 MHz, with VF ≤ 855 mV at 10 mA and Tamb = 25 °C. Reverse leakage remains ≤0.5 µA at VR = 80 V and 25 °C, supporting stable DC blocking in high-frequency analog switches.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 100 V - supports clamping in 3.3 V to 24 V logic-level and analog signal chains without breakdown. |
| Reverse Recovery Time (trr) | ≤4 ns - enables reliable operation up to ~100 MHz switching in sample-and-hold and RF detector circuits. |
| Junction Capacitance (Cd) | ≤1.5 pF at 0 V, 1 MHz - minimizes signal loading in 50 Ω transmission lines and antenna tuning networks. |
| Forward Voltage (VF) | ≤855 mV at 10 mA - ensures low conduction loss in low-power bias injection and level-shifting paths. |
| Reverse Leakage (IR) | ≤0.5 µA at VR = 80 V, 25 °C - maintains high-impedance isolation in precision sensor front-ends. |
| Thermal Resistance (Rth(j-a)) | 625 K/W on FR4 PCB - defines maximum continuous power dissipation of 200 mW at ambient ≤25 °C. |
Pinout & Package
Encapsulated in SC-70 (SOT323) plastic surface-mount package: 3-terminal, 1.3 mm pitch, 2.0 mm × 1.25 mm × 0.95 mm body, optimized for high-density PCB layouts and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Anode of Diode 1 | Input node for first clamping path; connects to signal source requiring bidirectional ESD protection. |
| 2 (A2) | Anode of Diode 2 | Independent input node for second clamping path; enables dual-rail or differential signal conditioning. |
| 3 (CC) | Common Cathode | Shared return path to reference rail (e.g., VCC or ground); simplifies layout and reduces parasitic inductance. |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | trr ≤ 4 ns ensures minimal timing skew in high-frequency digital signal routing and pulse shaping. |
| Low junction capacitance | Cd ≤ 1.5 pF preserves signal rise/fall times in >100 MHz applications without added RC delay. |
| Common-cathode dual-diode topology | Reduces component count and board area vs. discrete diode pairs in I/O protection and level translation. |
| Low forward voltage | VF ≤ 855 mV at 10 mA lowers power loss in always-on bias networks and active termination circuits. |
| Small-outline SMD package | SOT323 footprint occupies <2.5 mm² PCB area - compatible with automated placement and fine-pitch routing. |
Applications
| USB 2.0 Data Line Protection | RF Transceiver Bias Control |
|---|---|
Use Scenario: Clamping transient voltages on D+ and D− lines during hot-plug events and ESD discharge. IC Role / Device Role / Timing Role: Dual-anode, common-cathode diode pair provides symmetrical bidirectional clamping to VBUS and GND rails.

Use Value: Low IR (≤0.5 µA) ensures stable bias point; low Cd preserves impedance matching in 50 Ω systems. |
| Industrial Sensor Signal Conditioning | Low-Power Microcontroller I/O Protection |
Use Scenario: Protecting analog inputs of 12-bit ADCs from overvoltage transients in factory automation sensors. IC Role / Device Role / Timing Role: Common-cathode clamp limits input swing to safe range without loading sensitive op-amp outputs. Use Value: VF ≤ 855 mV ensures accurate zero-crossing detection; 100 V VR accommodates 24 V industrial bus surges. |
Use Scenario: Guarding GPIO pins against ESD and inductive kickback in battery-powered IoT nodes. IC Role / Device Role / Timing Role: Dual-diode structure provides rail-to-rail clamping for both high- and low-side I/O configurations. Use Value: SOT323 package fits space-constrained modules; ≤4 ns trr prevents latch-up during fast ESD pulses. |
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 | Same SOT323 package, but higher VF (≤1.25 V at 100 mA) and higher trr (≤6 ns); rated for 70 V VR instead of 100 V. | Less suitable for 24 V industrial clamping; acceptable for 3.3 V/5 V logic-level protection where speed margin is relaxed. | Select when lower cost is prioritized and 70 V VR suffices; verify trr impact on signal edge fidelity. |
| MMBD7000LT1G | SC-70 package, 100 V VR, but trr = 4 ns typical (not guaranteed max), and Cd = 2.0 pF - higher than BAV70W's 1.5 pF max. | Acceptable for general-purpose switching, but marginal in RF-sensitive applications due to higher capacitance. | Choose only if sourcing constraints require ON Semiconductor parts; confirm Cd tolerance in final design validation. |
Compared with BAV99W,115 and MMBD7000LT1G, the BAV70W uniquely guarantees ≤4 ns trr and ≤1.5 pF Cd within its 100 V VR rating - making it the preferred choice for high-fidelity signal clamping where timing and capacitance margins are critical.

FAQ
What is the maximum continuous forward current per diode in the BAV70W?
The BAV70W supports a maximum continuous forward current of 175 mA per diode at Tamb ≤ 25 °C, as specified in the Absolute Maximum Ratings table. Derating applies above 25 °C ambient, with total power dissipation limited to 200 mW on FR4 PCB. This rating assumes proper thermal relief and no simultaneous peak surge conditions.
Can the BAV70W be used in place of a single diode by leaving one anode unconnected?
Yes - either anode (A1 or A2) may be left unconnected without affecting device reliability or electrical performance. The internal diodes are fully isolated except for the shared cathode (CC), so unused anodes present no leakage or coupling path. However, PCB layout should avoid floating copper near unused pins to prevent parasitic coupling.
Is the BAV70W qualified for automotive applications?
No - the BAV70W is explicitly designated as non-automotive qualified per Nexperia's 2022 revision history. It lacks AEC-Q101 qualification and is not tested to automotive temperature, reliability, or stress requirements. For automotive use, Nexperia offers the BAV70W-Q series, which must be selected separately.
How does the common-cathode configuration affect PCB layout compared to dual-diode packages with separate cathodes?
The common-cathode configuration reduces required PCB real estate by eliminating one dedicated cathode trace and associated via. It also lowers inductance in the shared return path, improving high-frequency clamping effectiveness. Layout best practice is to route CC directly to a solid reference plane with minimal trace length, while keeping A1 and A2 traces symmetrical and impedance-controlled where signal integrity matters.
