2 / 2 page  Elektronische Bauelemente SZMD24C 100W, 24 V Transient Voltage Suppressors for ESD Protection 01-June-2002 Rev. A Page 2 of 2 http://www.SeCoSGmbH.com/ Any changes of specification will not be informed individually. RATINGS AND CHARACTERISTICS CURVES Applications Information Device Connection Options The SZMD series is designed to protect one bi-directional or two uni-directional data or l/O lines operating at 24 volts.Connection options are as follows: ‧Bidirectional:Pin 1 is connected to the data line and pin 2 is connected to ground (Since the device lls symmetrical,these conmtions may be re- Ver3ed).For best results,the ground connection should be made directly to a ground plane on the board.The path length should be kept as short as possible to minimize parasitic inductance-Pin 3 is not connected. ‧Unidirectional:Data lines are connected to pin1 and pin2.Pin 3 is connected to ground.For best results,this pin should be connected directly to a ground plane on the board.The path lengh should be kept as short as possible to minimize parasitic inductance. Circuit Board Layout Recommendations for suppres- sion of ESD. Good circuit board layout is critical for the suppression of fast rise-time transients such as ESD.The following guidelines are recommended (Refer to application note Sl99.01 for more detailed information): ‧Place the TVS near the input terminals or connec- tors to restrict transient coupling. ‧Minimize the path length between the TVS and the protected line. ‧Minimize all conductive loops including power and ground loops. ‧The ESD transient return path toground should be kept as short as possible. ‧Never run critical signals near board edges ‧Use ground planes whenever possib|e. 0 10 20 30 40 50 60 70 80 90 100 110 0 5 10 15 20 25 30 Time (us) e -t td = IPP /2 Wave form Paramete rs: tr = 8 s td = 20 s Pulse Waveform 0 10 20 30 40 50 60 70 80 90 100 110 0 25 50 75 100 125 150 Ambient Temperature - TA (oC) Power Derating Curve Clamping Voltage vs. Peak Pulse Current 0 10 20 30 4 0 50 60 0 1 2 3 Peak Pulse Current - IPP (A) Waveform Parameters tr = 8µs td = 20µ S |
