Overview
The Diotec Semiconductor BAV70W-AQ is a small signal diode array featuring two common cathode diodes in an SOT-323 surface-mount package. It is qualified to the AEC-Q101 automotive standard, ensuring suitability for demanding environments. The device provides a repetitive peak reverse voltage of 85 V and supports a maximum forward current of 150 mA per diode under single-diode loading conditions. Its junction temperature range spans from -55°C to +150°C, with a power dissipation rating of 200 mW.
Feature Summary
- Extremely high switching speed with reverse recovery time under 4 ns
- Low junction capacitance for minimal signal distortion
- Low leakage current characteristics across operating temperatures
- Compliant with RoHS directives and REACH regulations
Applications
- High-speed signal processing circuits
- Fast switching applications
- General rectifying tasks
Procurement Notes
Verify that the specific part number includes the -AQ suffix to confirm AEC-Q101 qualification status. Ensure the component matches the SOT-323 mechanical outline and marking code 'PH' as documented in the official datasheet. Confirm compliance requirements such as RoHS and REACH align with project specifications before finalizing procurement.
Selection Notes
Select this component when automotive-grade reliability is required for high-speed switching or signal processing. The common cathode configuration allows for efficient dual-diode integration within a compact footprint. Consider the low junction capacitance and fast reverse recovery time for maintaining signal integrity in high-frequency designs.
Part Context
This component belongs to Diotec's series of SMD small signal diodes, which also includes variants like BAS16W, BAW56W, BAV99W, and BAV199W. These devices share similar packaging and performance profiles but differ in internal connection types, such as common anode or single diode configurations. The -AQ suffix specifically denotes automotive qualification within this product family.
Replacement Considerations
Direct substitutes within the same family include BAV70W-Q (AEC-Q101 compliant) and standard commercial grades like BAV70W. Verify pinout compatibility and electrical ratings against the original design requirements before substitution.
