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, this page delivers verified electrical parameters, validated dual-diode topology, thermal resistance (625 K/W), and real-world switching performance data under pulsed IF = 10 mA conditions.
Technical Context
The BAV70W integrates two independent silicon switching diodes sharing a common cathode terminal, enabling compact dual-path clamping or steering without discrete pairing. Its trr ≤ 4 ns and Cd ≤ 1.5 pF at 1 MHz support >100 MHz signal integrity in high-frequency detector and sample-and-hold circuits.
Designed for surface-mount operation on FR4 PCBs with single-sided copper, it sustains 175 mA DC forward current per diode and 100 V repetitive peak reverse voltage, with junction temperature rated to 150 °C and thermal resistance Rth(j-a) = 625 K/W in free air.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 100 V - supports rail-to-rail clamping in 3.3 V–48 V logic interfaces without breakdown |
| Reverse Recovery Time (trr) | ≤4 ns - enables clean edge transitions in >100 MHz clock distribution and pulse shaping |
| Diode Capacitance (Cd) | ≤1.5 pF at 0 V - minimizes signal loading in RF detector and antenna switch bias networks |
| Forward Voltage (VF) | 855 mV at IF = 10 mA - ensures low conduction loss in active bias and level-shifting paths |
| Reverse Current (IR) | ≤0.5 µA at VR = 80 V - maintains high isolation in standby mode of analog multiplexers |
| Thermal Resistance (Rth(j-a)) | 625 K/W - defines derating curve for continuous operation on standard FR4 layout |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package: 3-terminal, 1.3 mm pitch, 2.0 mm × 1.25 mm × 0.95 mm body, optimized for reflow soldering with defined footprint per Figure 8.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input path for first diode; connects to signal source requiring unidirectional conduction |
| 2 | Anode (Diode 2) | Independent input path for second diode; enables dual-signal steering or redundancy |
| 3 | Common Cathode | Shared return node; simplifies PCB routing and reduces net count in dual-clamp designs |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | trr ≤ 4 ns ensures minimal timing skew in synchronous signal gating applications |
| Low junction capacitance | Cd ≤ 1.5 pF preserves bandwidth in 50 Ω RF signal paths up to 2 GHz |
| Common-cathode dual-diode topology | Reduces component count by 50% vs. discrete diode pairs in ESD clamp networks |
| Low leakage current | IR ≤ 0.5 µA at 80 V enables stable DC bias in high-impedance sensor interfaces |
Applications

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) | Less suitable for >500 MHz signal paths due to increased capacitance and slower recovery | Select when cost sensitivity outweighs sub-ns timing requirements |
| MMBD7000 | Identical trr (≤4 ns), but higher VR (100 V) and lower IR (≤100 nA at 25 V), in SOT23 package | Requires PCB redesign due to larger SOT23 footprint and non-common-cathode pinout | Choose only if ultra-low leakage at low VR is critical and board space allows SOT23 |
Compared with BAV99W and MMBD7000, the BAV70W uniquely balances 4 ns trr, 1.5 pF Cd, and common-cathode SOT323 packaging - making it optimal for space-constrained, high-frequency dual-path clamping where timing and layout efficiency are co-critical.

FAQ
What is the maximum continuous forward current per diode in the BAV70W?
The BAV70W supports 175 mA DC forward current per diode at Tamb ≤ 25 °C, as specified in Table 5 (Limiting values). Derating applies above 25 °C ambient, governed by Rth(j-a) = 625 K/W and Tj(max) = 150 °C. At 70 °C ambient, usable IF drops to approximately 100 mA per diode.
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, automotive-grade screening, and extended temperature validation. For automotive use, Nexperia offers the BAV70W-Q variant, which undergoes full automotive qualification and testing.
How does the common-cathode configuration affect PCB layout?
The common-cathode pin (Pin 3) allows both diodes to share a single low-inductance return path to the reference rail, reducing loop area and parasitic inductance. This configuration simplifies routing in ESD clamp networks and enables symmetrical placement relative to signal traces - critical for maintaining impedance control in RF layouts.
Is the BAV70W compatible with lead-free reflow soldering processes?
Yes - the BAV70W is qualified for lead-free reflow per J-STD-020, with a maximum peak temperature of 260 °C. Its SC-70 package outline and recommended solder land pattern (Figure 8) are optimized for standard Pb-free reflow profiles, including ramp-soak-reflow cycles with 60–90 s above 217 °C.
