Transient Voltage Suppressors

P4SMA Series

MERITEK

UL E223045

FEATURES

For surface mounted applications in order to optimize board space.

Low profile package.

Built-in strain relief.

Glass passivated junction.

Low inductance.

Excellent clamping capability.

Repetition Rate (duty cycle): 0.01%.

SMA/DO-214AC

Fast response time: typically less than 1.0ps from 0 volt to V^BRfor Unidirectional types.

Typical I^Rless than 1μA above 10V.

High Temperature soldering: 260°C/10 seconds at terminals.

MECHANICAL DATA

Case: JEDEC DO-214AC. Molded plastic over glass passivated junction.

Terminal: Solder plated, solderable per MIL-STD-750, Method 2026.

Polarity: Color band denotes cathode except Bidirectional.

Standard Packaging: 12mm tape (EIA STD RS-481).

Weight: 0.002 ounce, 0.061 grams.

DEVICES FOR BIPOLAR APPLICATION

For Bidirectional use CA suffix for type P4SMA6.8CA through type P4SMA550CA;

Electrical characteristics apply in both directions.
