DESIGN SUPPORT TOOLS click logo to get started
MECHANICAL DATA
Case: DO-35 (DO-204AH)
Weight: approx. 125 mg
Cathode band color: Black
Packaging codes/options:
TR/10K per 13" reel (52 mm tape), 50K/box
TAP/10K per ammopack (52 mm tape), 50K/box
FEATURES

• This diode features very low turn-on voltage and
fast switching. This device is protected by a PN
junction guard ring against excessive voltage,
such as electrostatic discharges
• This diode is also available in the SOD-123 case
with type designation BAT46W-V and in the
MiniMELF case with type designations LL46
• AEC-Q101 qualified
• Material categorization: for definitions of compliance
