BAS40-04-AQ is listed in the Diode Arrays range at ChipApex. The manufacturer field lists Diotec Semiconductor. Its product description is BAS40-04-AQ. Review the specifications below when checking this part for your BOM.
The BAS40-04-AQ is a small signal Schottky diode from Diotec Semiconductor, designed for surface mount applications in the SOT-23 package. It features an average forward current of 200 mA and a repetitive peak reverse voltage of 40 V. The device exhibits very high switching speed with a reverse recovery time under 5 ns and low junction capacitance below 5 pF. It operates within a junction temperature range up to 150°C for industrial grades and complies with AEC-Q101 standards.
Verify that the ordered component carries the specific -AQ suffix to confirm AEC-Q101 qualification status. Ensure the datasheet version matches the manufacturing batch requirements. Confirm compliance with RoHS, REACH, and Conflict Minerals regulations as stated in the official documentation before finalizing procurement specifications.
Select this component when automotive-grade reliability is required alongside fast switching performance. The -AQ suffix indicates AEC-Q101 qualification, distinguishing it from standard commercial or industrial grades. Consider the SOT-23 package constraints and thermal resistance values when designing for space-limited PCB layouts.
This part belongs to the BAS40 series of SMD small signal Schottky diodes manufactured by Diotec Semiconductor. The series includes variants like BAS40-04, BAS40-05, and BAS40-06, which differ in internal configuration such as single diode, series connection, common cathode, or common anode arrangements.
