SMBJ78A 数据手册

SMBJ5.0 thru 440CA

Surface Mount Transient Voltage Suppressors

Peak Pulse Power 600W Stand-off Voltage 5.0 to 440V

Features

ꢀ Plastic package has Underwriters Laboratory Flammability

Classification 94V-0

ꢀ Low profile package with built-in strain relief for surface

mounted applications

ꢀ Glass passivated junction

ꢀ Low incremental surge resistance, excellent clamping capability

ꢀ 600W peak pulse power capability with a 10/1000us

waveform, repetition rate (duty cycle): 0.01%

ꢀ Very fast response time

ꢀ High temperature soldering guaranteed:

250^oC/10 seconds at terminals

Mechanical Data

ꢀ Case: JEDEC DO-214AA(SMB J-Bend) molded plastic over

passivated junction

ꢀ Terminals: Solder plated, solderable per MIL-STD-750,

Method 2026

ꢀ Polarity: For unidirectional types the band denotes the cathode,

which is positive with respect to the anode under normal TVS

operation

ꢀ Weight: 0.003oz., 0.093g

Devices for Bidirectional Applications

For bi-directional devices, use suffix CA (e.g. SMBJ10CA). Electrical characteristics apply in both directions.
