Mechanical Data
Case: JEDEC DO-214AB (SMC) molded plastic over
passivated junction
Terminals: Solder plated, solderable per MIL-STD-750,
Method 2026. High temperature soldering: 250°C/10
seconds at terminals.
Polarity: For uni-directional types the band denotes the
cathode, which is positive with respect to the anode
under normal TVS operation.
Standard Packaging: 16mm tape (EIA STD RS-481)
Weight: 0.007 oz., 0.21 g
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
Features
• Low profile package with built-in strain relief for
surface mounted applications
• Glass passivated junction
• Low incremental surge resistance
• Low inductance
• Excellent clamping capability
• 1500W peak pulse power capability with a 10/1000µs
waveform, repetition rate (duty cycle): 0.01%
• Very fast response time
• Plastic package has Underwriters Laboratory
Flammability Classification 94V-0
Devices for Bidirectional Applications
For bi-directional devices, use suffix CA (e.g. 1.5SMC10CA). Electrical characteristics apply in both directions.
Maximum Ratings & Thermal Characteristics Ratings at 25°C ambient temperature unless otherwise specified.
