• Ideal for EFT protection of data lines in accordance with

IEC1000-4-4 (IEC801-4)

• Low profile package with built-in strain relief for

surface mounted applications

• Glass passivated junction

• Low incremental surge resistance, excellent clamping

capability

• 400W peak pulse power capability with a 10/1000µs wave-

form, repetition rate (duty cycle): 0.01% (300W above 91V)

Mechanical Data

Case: JEDEC DO-214AC molded plastic over

passivated chip

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

Method 2026. High temperature soldering guaranteed:

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.

Mounting Position: Any

Weight: 0.002 oz., 0.064 g

Packaging Codes – Options (Antistatic):

51 – 1K per Bulk box, 20K/carton

61 – 1.8K per 7" plastic Reel (12mm tape), 36K/carton

5A – 7.5K per 13" plastic Reel (12mm tape), 75K/carton

• Very Fast response time

Devices for Bidirectional Applications

For bi-directional devices, use suffix CA (e.g. P4SMA10CA). Electrical characteristics apply in both directions.

Maximum Ratings & Thermal Characteristics Ratings at 25°C ambient temperature unless otherwise specified.
