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 - used for signal routing and clamping in RF front-ends and digital logic interface protection.
For engineers reviewing the BAV70W datasheet, BAV70W pinout, BAV70W application, or BAV70W equivalent, key selection criteria include trr ≤ 4 ns at IF = 10 mA, VR = 100 V, common-cathode dual-diode topology, low-leakage performance at 80 V, 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 compact dual-path clamping or steering without inter-device mismatch. Its epitaxial construction delivers fast carrier recombination, directly supporting ≤4 ns trr under standardized 10 mA/10 mA test conditions.
Designed for surface-mount operation on standard FR4 boards, it exhibits 200 mW total power dissipation at Tamb ≤ 25 °C and junction temperature limits up to 150 °C - validated per IEC 60134 absolute maximum ratings with defined thermal footprint requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 100 V - supports DC blocking and transient suppression in 24 V and 48 V industrial signal lines |
| Reverse Recovery Time (trr) | ≤4 ns - enables reliable operation in >100 MHz switching applications such as RF detector biasing |
| Diode Capacitance (Cd) | ≤1.5 pF at 0 V - minimizes signal loading in high-frequency AC coupling paths |
| Forward Voltage (VF) | 855 mV at 10 mA - ensures low conduction loss in active clamping circuits |
| Reverse Current (IR) | ≤0.5 µA at VR = 80 V - maintains signal integrity in high-impedance sensing nodes |
| Thermal Resistance (Rth(j-a)) | 625 K/W - defines derating curve for continuous operation on standard single-sided FR4 PCB |
Pinout & Package
Encapsulated in SC-70 (SOT323), the BAV70W uses a 3-pin plastic surface-mount package measuring 2.0 mm × 1.25 mm × 0.95 mm with 1.3 mm lead pitch and standardized reflow footprint per Figure 8.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Anode of Diode 1 | Independent input path for first signal channel; routed separately to avoid crosstalk |
| 2 (A2) | Anode of Diode 2 | Independent input path for second signal channel; electrically isolated from A1 |
| 3 (CC) | Common Cathode | Shared output node enabling OR-ing, level shifting, or dual-input clamping to single rail |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | trr ≤ 4 ns enables use in >100 MHz clock/data line protection without timing skew |
| Low capacitance | Cd ≤ 1.5 pF preserves bandwidth in RF amplifier bias networks and antenna switch control |
| Common-cathode dual-diode topology | Reduces board space by 40% vs. discrete diode pairs while maintaining independent anode routing |
| Low leakage current | IR ≤ 0.5 µA at 80 V ensures minimal DC error in precision analog front-ends and sensor interfaces |
Applications
| RF Signal Clamping | Digital Logic Level Translation |
|---|---|
|
Use Scenario: Protecting LNA inputs from ESD transients in 2.4 GHz Wi-Fi front-end modules. IC Role / Device Role / Timing Role: Fast clamping diode pair limiting RF port voltage to ±0.7 V during ESD events. Use Value: 4 ns trr prevents transient energy from propagating into sensitive amplifier stages before TVS activation. |

IC Role / Device Role / Timing Role: Anode-referenced level shifter using forward-biased diode drop for voltage offset. Use Value: 855 mV VF at 10 mA provides stable 2.45 V logic-high threshold with <100 ps propagation delay impact. |
| High-Speed Data Line Protection | Switch-Mode Power Supply Feedback Snubbing |
|

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 | Same SOT323 package, but higher trr (≤6 ns) and higher Cd (≤2 pF); VF = 1.25 V at 150 mA | Less suitable for >100 MHz RF clamping due to slower recovery and higher capacitance | Select when higher forward current capability (150 mA) is required over speed optimization |
| MMBD7000 | Same trr ≤ 4 ns and VR = 100 V, but separate cathodes (not common-cathode); SOT23 package | Requires additional PCB routing for dual-cathode termination; larger footprint than SOT323 | Choose when independent cathode control is needed for asymmetric biasing or differential clamping |
Compared with BAV99W and MMBD7000, the BAV70W uniquely combines common-cathode topology, 4 ns trr, and 1.5 pF capacitance in the smallest SOT323 footprint - making it optimal for space-constrained, high-frequency dual-signal protection where shared return path simplifies layout.

FAQ
What is the maximum continuous forward current per diode in the BAV70W?
The BAV70W supports 175 mA continuous forward current per diode at ambient temperature ≤25 °C, as specified in Table 5 (Limiting values). Derating applies above 25 °C per the Rth(j-a) = 625 K/W thermal resistance value on FR4 PCB.
Can the BAV70W be used in automotive applications?
No - the BAV70W is explicitly marked as non-automotive qualified in its revision history (Table 8). It lacks AEC-Q101 qualification and has not undergone automotive stress testing; Nexperia offers separate -Q qualified variants for automotive use.
How does the common-cathode configuration affect PCB layout?
The common-cathode (CC) pin allows both diodes to share one ground or reference node, reducing trace count and minimizing loop area in high-frequency layouts. This configuration simplifies ESD protection routing for differential pairs like USB or LVDS without requiring separate cathode vias.
Is the BAV70W compatible with lead-free reflow soldering processes?
Yes - the BAV70W is rated for lead-free reflow per JEDEC J-STD-020, with peak temperature tolerance up to 260 °C. Its recommended reflow profile aligns with standard Pb-free thermal profiles, and the SOT323 footprint in Figure 8 supports automated placement and soldering.
