P4SMA Series  
Vishay General Semiconductor  
Surface Mount TRANSZORB® Transient Voltage Suppressors  
FEATURES  
• Low profile package  
• Ideal for automated placement  
• Glass passivated chip junction  
• Available in uni-directional and bi-directional  
400 W peak pulse power capability with a  
10/1000 µs waveform, repetitive rate (duty  
cycle): 0.01 % (300 W above 91 V)  
• Excellent clamping capability  
• Very fast response time  
DO-214AC (SMA)  
• Low incremental surge resistance  
• Meets MSL level 1, per J-STD-020, LF maximum  
peak of 260 °C  
• Solder dip 260 °C, 40 s  
• Component in accordance to RoHS 2002/95/EC  
and WEEE 2002/96/EC  
PRIMARY CHARACTERISTICS  
TYPICAL APPLICATIONS  
VBR uni-directional  
6.8 V to 540 V  
6.8 V to 220 V  
400 W, 300 W  
3.3 W  
Use in sensitive electronics protection against  
voltage transients induced by inductive load switching  
and lighting on ICs, MOSFET, signal lines of  
sensor units for consumer, computer, industrial and  
telecommunication.

Base P/N-E3 - RoHS compliant, commercial grade  
Base P/NHE3 - RoHS compliant, high reliability/  
automotive grade (AEC Q101 qualified)  
Terminals: Matte tin plated leads, solderable per  
J-STD-002 and JESD22-B102  
DEVICES FOR BI-DIRECTION APPLICATIONS  
For bi-directional devices use CA suffix (e.g.  
P4SMA10CA).  
Electrical characteristics apply in both directions.  
E3 suffix meets JESD 201 class 1A whisker test, HE3  
suffix meets JESD 201 class 2 whisker test  
Polarity: For uni-directional types the band denotes  
cathode end, no marking on bi-directional types
