ST2451D4
1-Line Uni-directional TVS Diode
Description
Mechanical Characteristics
The ST2451D4 is a 24V uni-directional TVS diode, utiliz-
ing leading monolithic silicon technology to provide fast
response time and low ESD clamping voltage, making
this device an ideal solution for protecting voltage sensi-
tive data and power line. The ST2451D4 complies with
IEC 61000-4-2 (ESD) standard with ±15 kV air and ±8 kV
contact discharge. It is assembled into an ultra-small
1.0x0.6x0.5mm lead-free DFN package. The small size
and high ESD surge protection make ST2451D4 an ideal
choice to protect cell phone, digital cameras, audio play-
ers and many other portable applications.
Package: DFN1006-2 (1.0×0.6×0.5mm)
Lead Finish: NiPdAu
Case Material: “Green” Molding Compound.
UL Flammability Classification Rating 94V-0
Moisture Sensitivity: Level 3 per J-STD-020
Terminal Connections: See Diagram Below
Marking Information: See Below
