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 junction capacitance-used for signal routing and clamping in RF front-ends and digital logic interfaces.
For engineers reviewing the BAV70W datasheet, BAV70W pinout, BAV70W application, or BAV70W equivalent, this page delivers verified electrical parameters, validated dual-anode/common-cathode terminal mapping, thermal resistance data, and real-world switching use cases-not generic diode descriptions.
Technical Context
The BAV70W integrates two independent silicon switching diodes sharing a single cathode terminal, enabling compact dual-path clamping or steering without discrete pairing. Its low trr (≤4 ns) and Cd (≤1.5 pF) support operation up to ~300 MHz in small-signal AC coupling and ESD protection circuits.
Designed for surface-mount assembly on FR4 PCBs with standard reflow footprints, it operates across −65 °C to +150 °C ambient and sustains 175 mA DC forward current per diode at 25 °C, with thermal resistance Rth(j-a) = 625 K/W under defined board conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 100 V - supports rail-to-rail clamping in 24 V industrial I/O and 48 V telecom line interfaces |
| Reverse Recovery Time (trr) | ≤4 ns - enables clean edge transitions in >100 Mbps digital signal routing and pulse shaping |
| Junction Capacitance (Cd) | ≤1.5 pF at 0 V - minimizes signal loading in 50 Ω RF paths and high-frequency clock distribution |
| Forward Voltage (VF) | 855 mV at 10 mA - ensures low conduction loss in active bias networks and level-shifting diode logic |
| Reverse Leakage (IR) | ≤0.5 µA at 80 V, 25 °C - maintains signal integrity in high-impedance sensor front-ends and sample-hold circuits |
| Total Power Dissipation (Ptot) | 200 mW at 25 °C - defines maximum continuous dual-diode switching duty in space-constrained SMT layouts |
Pinout & Package
Package: SOT323 (SC-70), 3-terminal plastic surface-mount package measuring 2.0 mm × 1.25 mm × 0.95 mm with 1.3 mm lead pitch and standard FR4 reflow footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input node for first diode path; used for signal steering or clamp anode in dual-channel configurations |
| 2 | Anode (Diode 2) | Independent input node for second diode path; enables differential clamping or dual-rail protection |
| 3 | Common Cathode | Shared output/return node; simplifies PCB routing by eliminating separate cathode traces for both diodes |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | trr ≤ 4 ns enables reliable operation in 100+ Mbps serial data lines and fast PWM control feedback paths |
| Low junction capacitance | Cd ≤ 1.5 pF preserves bandwidth in 50 Ω RF detector inputs and antenna switch bias networks |
| Common-cathode dual-diode topology | Reduces component count and layout area vs. two discrete SOT23 diodes in clamping or OR-ing applications |
| Thermal robustness | Rth(j-a) = 625 K/W on standard FR4 allows sustained 100 mA dual-diode conduction without derating at 70 °C ambient |
Applications
| RF Signal Clamping | Digital Logic Level Translation |
|---|---|
Use Scenario: Protecting LNA input stages from transient overvoltage while preserving small-signal gain and noise figure. IC Role / Device Role / Timing Role: Passive clamping element placed between antenna feedline and RF IC input pin. Use Value: ≤1.5 pF capacitance avoids detuning of matching networks; ≤4 ns trr prevents distortion of sub-ns RF pulses. |
Use Scenario: Translating 3.3 V microcontroller GPIO outputs to interface with 5 V legacy peripherals. IC Role / Device Role / Timing Role: Anode-referenced level shifter using forward-biased diode drop. Use Value: 855 mV VF at 10 mA ensures predictable 2.45 V logic-high threshold; common cathode simplifies ground-return routing. |
| High-Speed Data Line Protection | Switch-Mode Power Supply Feedback Isolation |
Use Scenario: ESD and overvoltage protection on USB 2.0 D+/D− lines without degrading signal integrity. IC Role / Device Role / Timing Role: Bidirectional clamping diode pair referenced to VBUS and GND rails. Use Value: Dual-anode configuration allows symmetric clamping to both supply and ground; ≤4 ns trr avoids data eye closure. |
Use Scenario: Isolating optocoupler feedback signals from primary-side controller in flyback converters. IC Role / Device Role / Timing Role: Fast-recovery diode in snubber network and bias path for TL431 reference. Use Value: 100 V VR rating withstands reflected flyback spikes; 175 mA IF rating supports stable bias current under load transients. |
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,115 | Same SOT323 package, but higher trr (≤6 ns) and higher Cd (≤2 pF); VF = 1.25 V at 150 mA | Better suited for moderate-speed (<50 Mbps) clamping where lower VF at high current matters more than ultra-low capacitance | Select when forward conduction efficiency at >50 mA dominates over RF bandwidth preservation |
| MMBD7000LT1G | SC-70 package, trr = 4 ns, Cd = 2 pF, VR = 70 V, VF = 715 mV at 1 mA | Limited to ≤70 V systems; lower leakage (30 nA at 25 V) but reduced voltage margin for industrial 48 V lines | Prefer for low-leakage analog front-ends below 70 V, where tighter IR spec outweighs VR headroom needs |
Compared with BAV99W,115 and MMBD7000LT1G, the BAV70W uniquely balances 100 V VR, ≤4 ns trr, and ≤1.5 pF Cd in a common-cathode SOT323-making it optimal for RF-sensitive, high-voltage digital interface protection where layout area and signal fidelity are constrained.

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 the Absolute Maximum Ratings table. Derating applies above 25 °C ambient, with full derating to zero at 150 °C junction temperature. This rating assumes mounting on FR4 PCB with standard copper area per datasheet footnote [2].
Can the BAV70W be used in bidirectional ESD protection circuits?
Yes-the BAV70W's common-cathode dual-anode structure allows implementation of bidirectional clamping by connecting Pin 1 and Pin 2 to differential signal lines (e.g., USB D+/D−) and Pin 3 to a low-impedance return path such as VBUS or GND, provided external series impedance limits peak current during ESD events.
Is the BAV70W automotive-qualified?
No-the July 2022 datasheet explicitly states this device is non-automotive qualified and superseded earlier automotive-grade versions. It lacks AEC-Q101 qualification and is not tested to automotive temperature, reliability, or stress requirements. For automotive use, Nexperia recommends its BAV70W-Q series variants.
What is the thermal resistance from junction to ambient for the BAV70W?
The thermal resistance Rth(j-a) is 625 K/W under defined test conditions: mounted on FR4 PCB with single-sided 1 oz copper, tin-plated, and using the standard SOT323 footprint. This value assumes free-air convection and does not include heatsinking or forced airflow effects.
