AI summary

BAS40Q product

BAS40Q is an AEC-Q101-qualified 40 V small-signal Schottky diode in SOT-23, intended for fast switching, voltage clamping, and automotive electronics.

Best for

Automotive-qualified low-current switching
Voltage-clamping circuits
Low-capacitance signal paths

Avoid if

Average forward current exceeds 120 mA
Reverse voltage can exceed 40 V
A higher-power rectifier package is required

Check before use

Confirm the BAS40Q diode topology and pin assignment
Check worst-case junction temperature and reverse leakage
Verify SOT-23 pad layout and thermal derating
