Product details
Overview
BAV70-7-F from Diodes Incorporated is a dual surface-mount switching diode in SOT23 package, featuring 75 V peak repetitive reverse voltage, 300 mA forward continuous current, 4.0 ns reverse recovery time, and 2.0 pF junction capacitance at 0 V. It serves as a high-speed signal routing and clamping element in digital logic interfaces and analog front-end protection circuits.
For engineers reviewing the BAV70-7-F datasheet, BAV70-7-F pinout, BAV70-7-F application, or BAV70-7-F equivalent, key selection criteria include fast switching performance (trr ≤ 4.0 ns), low forward voltage (VF ≤ 0.855 V @ 10 mA), dual-diode integration in compact SOT23, and RoHS-compliant lead-free construction for automated PCB assembly.
Technical Context
The BAV70-7-F integrates two independent silicon switching diodes in a single SOT23-3 package with common cathode configuration, confirmed by internal schematic and top-view marking diagram. Its fast recovery (trr = 4.0 ns) and low capacitance (CT = 2.0 pF @ 1 MHz, VR = 0 V) support high-frequency signal steering up to ~100 MHz in discrete logic and RF bias networks.
Thermal design is constrained by RθJA = 357 °C/W on FR-4 with 1-inch² 2 oz copper pad, limiting continuous power dissipation to 350 mW at 25°C ambient and derating linearly to zero at 150°C. Operating temperature range spans –55°C to +150°C, enabling use in industrial and under-hood automotive environments when qualified as BAV70Q.
Key Specifications

Applications
| USB 2.0 Data Line Protection | Logic-Level Signal Clamping |
|---|---|
Use Scenario: Protecting D+ and D– lines from ESD transients and overvoltage during hot-plug insertion. IC Role / Device Role / Timing Role: Dual-anode clamping diode with common cathode tied to VBUS or GND, diverting ±8 kV HBM surges away from PHY IC pins. Use Value: 4.0 ns trr prevents pulse distortion during 480 Mbps data bursts; 2.0 pF CT avoids signal rise-time degradation. | Use Scenario: Level-shifting and overvoltage limiting between 3.3 V microcontroller GPIO and 5 V peripheral logic. IC Role / Device Role / Timing Role: Forward-biased clamp limiting input voltage to VF + rail, reverse-biased blocking of negative excursions. Use Value: VF ≤ 0.855 V @ 10 mA ensures minimal logic threshold shift; 75 V VRRM accommodates 5 V rail transients. |
| RF Detector Bias Network | Automotive LIN Bus Transceiver Protection |
Use Scenario: Providing DC bias and AC coupling isolation in crystal-limited RF envelope detectors (e.g., 868 MHz ISM band). IC Role / Device Role / Timing Role: Low-capacitance switch isolating detector output from bias supply while passing RF envelope signals. Use Value: 2.0 pF CT preserves detector bandwidth; 300 mA IFM supports bias current stability under modulation peaks. | Use Scenario: Protecting LIN transceiver RX/TX pins against load-dump and battery-reverse events in vehicle door modules. IC Role / Device Role / Timing Role: Common-cathode dual diode shunting positive transients to VBAT and negative spikes to GND. Use Value: 150°C TJ rating ensures reliability in sealed junction boxes; AEC-Q101-qualified BAV70Q variant available for full compliance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBD7000LT1G | Higher VF (0.95 V @ 10 mA), same trr (4 ns), identical SOT23-3 package and common-cathode topology | Slightly higher conduction loss in low-voltage clamping; otherwise functionally interchangeable in USB and logic protection | Select when cost optimization is prioritized and VF margin ≥ 0.1 V is acceptable |
| BAT54C | Lower VRRM (30 V), higher CT (10 pF), same IFM (300 mA), Schottky barrier (vs. PN junction) | Not suitable for 48 V systems or >50 MHz signal paths due to reduced blocking voltage and higher capacitance | Choose only for low-voltage (<5 V), low-frequency (<10 MHz) applications where ultra-low VF (0.33 V) is critical |
Compared with MMBD7000LT1G and BAT54C, the BAV70-7-F delivers optimal balance of 75 V blocking, 4.0 ns speed, and 2.0 pF capacitance for mid-voltage, high-frequency signal routing-making it preferred for USB 2.0, industrial I/O, and RF detector designs where both voltage headroom and bandwidth matter.

FAQ
What is the pin configuration of BAV70-7-F and how is polarity identified?
BAV70-7-F uses SOT23-3 package with Pin 1 = Anode 1, Pin 2 = Common Cathode, Pin 3 = Anode 2. Polarity is marked by a cathode bar adjacent to Pin 2 on the top surface, confirmed in the device's internal schematic and mechanical drawing DS12006 Rev. 25–2 Figure 1. The marking code "Kxx YM" appears adjacent to the cathode bar.
Is BAV70-7-F suitable for automotive applications?
BAV70-7-F is not AEC-Q101 qualified. For automotive use, Diodes specifies the BAV70Q-7-F variant, which is AEC-Q101 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities. BAV70-7-F is rated for –55°C to +150°C operation but lacks automotive change control documentation and qualification testing.
How does BAV70-7-F compare to single-diode equivalents like 1N4148W in SOD-123?
BAV70-7-F provides two independent diodes in one SOT23-3 footprint, reducing PCB area by ~60% versus two 1N4148W devices. It matches 1N4148W's 4 ns trr and 75 V VRRM but offers lower CT (2.0 pF vs. ~4 pF) and tighter VF distribution, making it superior for dual-path high-frequency signal conditioning.
What is the maximum continuous forward current and how is it thermally limited?
The BAV70-7-F supports 300 mA continuous forward current when mounted on an FR-4 board with a 1 inch², 2 oz copper pad, per Note 6 in DS12006. Power dissipation is limited to 350 mW at 25°C ambient, derating linearly to zero at 150°C using RθJA = 357 °C/W - verified by the Fig. 1 power derating curve in the datasheet.
