Features
• Underwriters Laboratory Recognition under UL standard
for safety 497B: Isolated Loop Circuit Protection
• Low profile package with built-in strain relief for
surface mounted applications
• Glass passivated junction
• Low incremental surge resistance, excellent clamping
capability
• 1500W peak pulse power capability with a 10/1000µs
waveform, repetition rate (duty cycle): 0.01%
• Very fast response time
• High temperature soldering guaranteed:
250°C/10 seconds at terminals
Mechanical Data
Case:
JEDEC DO-215AB 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:
0.007 oz., 0.21 g
Flammability:
Epoxy is rated UL 94V-0
Packaging Codes – Options (Antistatic):
51 – 1K per Bulk box, 10K/carton
57 – 850 per 7" plastic Reel (16mm tape), 8.5K/carton
9A – 3.5K per 13" plastic Reel (16mm tape), 35K/carton
Devices for Bidirectional Applications
For bi-directional devices, use suffix C or CA (e.g. SMCJ10C, SMCJ10CA). Electrical characteristics apply in both directions.
