DLP3V3DTZ
DUAL UNIDIRECTIONAL AND SINGLE BIDIRECTIONAL TVS
General Description
· This Transient Voltage Suppressor (TVS) diode is designed
for dual uni-directional or single bi-directional protection for
data lines, components or circuits from damage due to
electrostatic discharge (ESD), cable discharge events(CDE)
and lightning (see IPPM below). It offers high ESD capability,
low reverse leakage, low junction capacitance and low
clamping voltage over range of temperature. They are
suitable for computers, communication systems, hand held
portables, high density PC boards and peripherals.
Features
· 372 Watts Peak Pulse Power (tp=8/20 mS)
· AEC-Q101 (Human Body Model- 8kV, Machine Model-400V)
and 25 KV(air)/ 8 KV(contact) as per IEC61000-4-2(ESD)
· Dual Unidirectional and Single Bidirectional Configuration
· Lead Free By Design/ROHS Compliant (Note 2)
· "Green" Device (Note 3)
· Surface Mount Package Suited for Automated Assembly
Mechanical Data
· Case: SOT-23
· Case Material: "Green Molding" Compound (Molded
Plastic). UL Flammability Classification Rating 94V-0
· Moisture Sensitivity: Level 1 per J-STD-020C
· Terminal Connections: See Fig. 1
· Terminals: Finish - Matte Tin annealed over Alloy 42
leadframe. Solderable per MIL-STD-202, Method 208
· Marking & Type Code Information: See Last Page
· Ordering Information: See Page 6
· Weight: 0.008 grams (approximate)
