Transient Suppression Diodes
For General Purpose Use
GENERAL DESCRIPTION
The SMAJ, SMBJ, and SMCJ Series are a popular format of general purpose
transient voltage suppression diodes. They are based on the low leakage,
high reliability, but low cost glass passivated chip rectifier technology.
FEATURES
• Glass passivated chip
• 400W, 600W and 1500W types (10/1000us)
• Low leakage
• Flat clamping
• Very fast response time
• Halogen Free
• ≤1μA leakage for 12V and up
• Lead-Free Terminations
APPLICATIONS
• Consumer
• Industrial
• Telecom
• Computer
