SMAJ530, SMAJ550 www.vishay.com Vishay General Semiconductor Surface Mount TRANSZORB(R) Transient Voltage Suppressors FEATURES * Glass passivated chip junction * Available in uni-directional polarity only * Excellent clamping capability * Very fast response time * Low incremental surge resistance * Meets MSL level 1, per J-STD-020, LF maximum peak of 260 C * AEC-Q101 qualified * Material categorization: For definitions of compliance please see www.vishay.com/doc?99912 DO-214AC (SMA) 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. PRIMARY CHARACTERISTICS VBR (uni-directional) 530 V to 550 V VWM 477 V, 495 V PPPM 300 W PD 2.5 W IFSM (uni-directional only) 40 A TJ max. 150 C MECHANICAL DATA Polarity Uni-directional Package DO-214AC (SMA) Case: DO-214AC (SMA) Molding compound meets UL 94 V-0 flammability rating Base P/N-E3 - RoHS-compliant and commercial grade Base P/NHE3 - RoHS-compliant and AEC-Q101 qualified Base P/NHE3_X - RoHS-compliant and AEC-Q101 qualified ("_X" denotes revision code e.g. A, B, .....) APPLICATION NOTES * Respect thermal resistance (PCB Layout) - as the temperature coefficient also contributes to the clamping voltage Terminals: Matte tin plated leads, solderable per J-STD-002 and JESD 22-B102 E3 suffix meets JESD 201 class 2 whisker test, HE3 suffix meets JESD 201 class 2 whisker test Polarity: Color band denotes cathode end * Select minimum breakdown voltage, so you get acceptable power dissipation and PCB tie point temperature * Devices with higher breakdown voltage will have a shorter conduction time and will dissipate less power * Clamping voltage is influenced by internal resistance design approximation is 7 V per 100 mA slope * Keep temperature of TVS lower than TOPSwitch(R) as a recommendation * Maximum current is determined by the maximum TJ and can be higher than 300 mA * Contact supplier for current arrangements different clamping voltage/ * Minimum breakdown voltage can be customized for other applications.
