Product details
Overview
BAV70W-7-F from Diodes Incorporated is a dual surface-mount switching diode in SOT323 package, rated for 75 V peak repetitive reverse voltage, 300 mA forward current, and featuring 4 ns reverse-recovery time and 2.0 pF junction capacitance. It serves as a high-speed signal routing or clamping element in low-power analog and digital interface circuits.
For engineers reviewing the BAV70W-7-F datasheet, BAV70W-7-F pinout, BAV70W-7-F application, or BAV70W-7-F equivalent, this part is selected for fast-switching, low-capacitance requirements in compact PCB layouts where thermal resistance (625 °C/W) and RoHS-compliant green packaging are critical design constraints.
Technical Context
The BAV70W-7-F integrates two independent silicon switching diodes in a single SOT323 package with common cathode configuration per the internal schematic. Its 4 ns trr and sub-2.0 pF CT enable use in 10–100 MHz signal path switching and RF detector applications.
Rated for -55°C to +150°C operation and 200 mW power dissipation on FR-4, it supports stable performance in thermally constrained environments without derating below 70°C ambient. The device uses matte tin-plated Alloy 42 leads and green molding compound compliant with UL 94V-0 and J-STD-020 Level 1 moisture sensitivity.

Applications
| USB 2.0 Data Line Protection | Low-Voltage Logic-Level Translation |
|---|---|
Use Scenario: Bidirectional ESD suppression and overvoltage clamping on D+ and D− lines of USB 2.0 ports. IC Role / Device Role / Timing Role: Dual clamping diode providing low-capacitance path to VBUS or GND during transient events. Use Value: 2.0 pF CT avoids signal integrity degradation at 480 Mbps; 4 ns trr prevents latch-up during fast transients. |
Use Scenario: Level shifting between 3.3 V microcontroller GPIO and 5 V peripheral I/O with open-drain compatibility. IC Role / Device Role / Timing Role: Passive voltage translator using forward conduction threshold and common-cathode topology. Use Value: 0.715 V VF at 1 mA ensures reliable turn-on at low drive strength; 75 V VRRM accommodates bus overshoot. |
| RF Detector Bias Network | Power Supply Sequencing Clamp |
Use Scenario: DC bias injection and AC coupling isolation in 900 MHz ISM-band RF detector front-ends. IC Role / Device Role / Timing Role: Low-Cj blocking diode isolating bias rail from RF signal path while passing DC. Use Value: 2.0 pF CT minimizes insertion loss below -0.2 dB at 900 MHz; SOT323 footprint fits tight RF layout spacing. |
Use Scenario: Preventing backfeed between multiple regulated rails (e.g., 3.3 V and 1.8 V) during power-up sequencing. IC Role / Device Role / Timing Role: Isolation diode ensuring monotonic voltage ramp and avoiding cross-rail current surge. Use Value: 300 mA IF rating handles peak inrush; 625 °C/W θJA allows operation without heatsink in 12 mm² area. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99W-7-F | Higher VRRM (100 V), slightly higher CT (2.5 pF), same SOT323 package and trr (4 ns) | Better suited for 12 V system interfaces; marginal penalty in 500+ MHz RF paths due to +0.5 pF | Select when reverse voltage margin >25 V is required and RF bandwidth <300 MHz |
| MMBD7000LT1G | Lower VF (0.625 V @ 10 mA), same VRRM (70 V), identical trr (4 ns), but higher CT (3.5 pF) | Preferred for low-threshold logic clamping; unsuitable for >100 MHz signal paths due to 75% higher capacitance | Choose for battery-powered 3.3 V systems needing lower forward drop, not high-frequency signal integrity |
Compared with BAV99W-7-F and MMBD7000LT1G, the BAV70W-7-F delivers optimal balance of low capacitance, moderate voltage rating, and industry-standard thermal performance-making it the preferred choice for USB, logic-level, and mid-band RF applications where board space and signal fidelity are jointly constrained.

FAQ
Is BAV70W-7-F pin-compatible with BAV99W-7-F?
Yes - both use identical SOT323 package with common-cathode pinout (Anode–Cathode–Anode). Mechanical and electrical pin mapping matches exactly, enabling direct substitution where voltage and capacitance specifications align with design margins.
What is the maximum continuous forward current per diode element?
The BAV70W-7-F supports 300 mA continuous forward current per diode, measured under standard JEDEC conditions (FR-4 board, 1″×1″ 2 oz copper pad). Derating begins above 70°C ambient per Figure 1's linear power curve.
Does BAV70W-7-F meet AEC-Q101 for automotive use?
No - only the BAV70WQ-7-F variant is AEC-Q101 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities. The BAV70W-7-F is intended for commercial and industrial applications, not automotive-grade deployment.
Can BAV70W-7-F be used in place of a single SOT23 diode?
Yes - either anode terminal (Pin 1 or Pin 3) can be used independently with the common cathode (Pin 2) grounded or biased, effectively functioning as a standalone switching diode while leaving the second element unused or reserved for redundancy.
