SMAJ530 & SMAJ550  
Vishay General Semiconductor  
Surface Mount TRANSZORB® Transient Voltage Suppressors  
FEATURES  
• Glass passivated chip junction  
• Available in Unidirectional polarity only  
• Excellent clamping capability  
• Very fast response time  
• Low incremental surge resistance  
• Meets MSL level 1, per J-STD-020C, LF max peak  
of 260 °C  
• Solder Dip 260 °C, 40 seconds  
DO-214AC (SMA)  
• Component in accordance to RoHS 2002/95/EC  
and WEEE 2002/96/EC  
APPLICATION NOTES  
MAJOR RATINGS AND CHARACTERISTICS  
• Respect Thermal Resistance (PCB Layout) - as the  
temperature coefficient also contributes to the  
clamping voltage  
VWM  
PPPM  
PD  
530 V, 550 V  
300 W  
2.5 W  
• Select minimum breakdown voltage, so you get  
acceptable power dissipation and PCB tie point  
temperature  
IFSM  
40 A  
Tj max.  
150 °C  
• Devices with higher breakdown voltage will have a  
shorter conduction time and will dissipate less  
power  
TYPICAL APPLICATIONS  
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, automotive and  
telecommunication.  
• Clamping voltage is influenced by internal resistance  
- design approximation is 7 V per 100 mA slope  
®
• Keep temperature of TVS lower than TOPSwitch  
as a recommendation  
• Maximum current is determined by the maximum T  
and can be higher than 300 mA  
j
MECHANICAL DATA  
Case: DO-214AC (SMA)  
Epoxy meets UL 94V-0 flammability rating  
• Contact supplier for different clamping voltage/  
current arrangements  
Terminals: Matte tin plated leads, solderable per  
• Minimum breakdown voltage can be customized for  
other applications. Contact supplier  
J-STD-002B and JESD22-B102D  
E3 suffix for commercial grade, HE3 suffix for high  
reliability grade (AEC Q101 qualified)
