Diodes Incorporated BAV70Q-13-F

Overview

BAV70Q-13-F from Diodes Incorporated is a dual high-speed switching diode in SOT23 package, rated for 75 V peak repetitive reverse voltage, 300 mA forward continuous current, and 4.0 ns reverse recovery time. It delivers low forward voltage (0.715 V @ 1 mA) and low junction capacitance (2.0 pF @ 0 V), enabling efficient signal routing and clamping in automotive-grade analog front-ends and power management circuits.

For engineers reviewing the BAV70Q-13-F datasheet, BAV70Q-13-F pinout, BAV70Q-13-F application, or BAV70Q-13-F equivalent, key selection criteria include AEC-Q101 qualification, IATF 16949 manufacturing compliance, thermal resistance (357 °C/W), fast switching performance, and dual-diode configuration for compact signal path protection.

Technical Context

The BAV70Q-13-F integrates two independent silicon epitaxial planar switching diodes in a single SOT23-3 package with common cathode configuration (Pin 1: Anode 1, Pin 2: Cathode, Pin 3: Anode 2). Its 4.0 ns trr and low CT (2.0 pF) support high-frequency signal steering up to ~100 MHz in discrete logic interfaces and RF detector stages.

Designed for automotive environments, it operates across –55 °C to +150 °C with full AEC-Q101 stress qualification, PPAP capability, and halogen/antimony-free "Green" construction meeting RoHS 3 (2015/863/EU). Thermal derating begins at +25 °C per the 357 °C/W RθJA rating on standard FR-4 layout.

FAQ

What is the pin configuration of BAV70Q-13-F?

BAV70Q-13-F uses a standard SOT23-3 package with Pin 1 as Anode 1, Pin 2 as the common cathode, and Pin 3 as Anode 2. This dual-anode/common-cathode arrangement is confirmed in the internal schematic on page 2 of DS12006 Rev. 25–2 and matches the top-view marking diagram showing "Kxx YM KJJ" orientation.

Is BAV70Q-13-F suitable for 12 V automotive power rail protection?

Yes - its 75 V peak repetitive reverse voltage exceeds the ISO 7637-2 Load Dump pulse requirement (up to 60 V), and its 300 mA forward current rating supports typical bias and sensing currents in BCM and lighting control modules. The AEC-Q101 qualification confirms suitability for direct connection to 12 V systems.

How does BAV70Q-13-F differ from standard BAV70-13-F?

BAV70Q-13-F adds AEC-Q101 qualification, PPAP capability, and manufacturing in IATF 16949-certified facilities. Electrically identical, it includes enhanced change control, lot traceability, and automotive-specific reliability testing - whereas BAV70-13-F is intended for commercial/industrial use without automotive process controls.

Can BAV70Q-13-F replace BAT54S in a common-cathode application?

Yes - both are SOT23-3 dual common-cathode Schottky-like switching diodes. However, BAV70Q-13-F has higher VRRM (75 V vs. 30 V), slower trr (4.0 ns vs. 5 ns), and lower VF at low current (0.715 V @ 1 mA vs. 0.8 V). It is not a Schottky device but a high-speed silicon PN diode, offering better reverse leakage stability at high temperature.
