05100 Only One Name Means ProTek’Tion™ PLC497 uLtRa Low CaPaCitanCe steeRing diode/tVs aRRay desCRiPtion The PLC497 is an ultra low capacitance steering diode/TVS array. Designed for protection against Electrostatic Discharge (ESD), Electrical Fast Transients (EFT) and secondary lightning threats, this device is ideal for use in high-speed signal interface applications. The PLC497 is available in the small SOT-23 package, which reduces internal lead inductance for low overshoot voltage during fast front time transient events like ESD. This device meets the IEC 61000-4-2 and IEC 61000-4-4 requirements. sot-23 PaCkage FeatuRes • Compatible with IEC 61000-4-2 (ESD): Air 15kV, Contact 8kV • Compatible with IEC 61000-4-4 (EFT): 40A, 5/50ns • Compatible with IEC 61000-4-5 (Surge): 20A, 8/20µs - Level 2(LineGround) & Level 3(Line-Line) • ESD Protection > 25 kilovolts • 200 Watts Peak Pulse Power per Line(tp = 8/20µs) • Low Clamping Voltage < 5 Volts • Ultra Low Capacitance: 2.5pF • RoHS Compliant • REACH Compliant aPPLiCations • • • • Low Voltage Wireless Equipment Sensor & Control Circuits Ethernet 10/100/1000 Base T FireWire Interfaces/Connections meChaniCaL ChaRaCteRistiCs • • • • Molded JEDEC SOT-23 Package Approximate Weight: 8 milligrams Lead-Free Pure-Tin Plating (Annealed) Solder Reflow Temperature: Pure-Tin - Sn, 100: 260-270°C • Flammability Rating UL 94V-0 • 8mm Tape and Reel per EIA Standard 481 Pin ConFiguRation 1 3 2 05100.R8 9/10 Page 1 www.protekdevices.com 05100 Only One Name Means ProTek’Tion™ PLC497 tyPiCaL deViCe ChaRaCteRistiCs maXimum Ratings @ 25°C unless otherwise specified PaRameteR Peak Pulse Power (tp = 8/20µs) - See Figure 1 Peak Pulse Current - IPP Max (tp = 8/20µs) Operating Temperature Storage Temperature symBoL PPP IPP TL TSTG VaLue 200 20 -55 to 150 -55 to 150 units Watts Amps °C °C eLeCtRiCaL ChaRaCteRistiCs PeR Line @ 25°C unless otherwise specified PaRt numBeR deViCe maRking Rated stand-oFF VoLtage minimum BReakdown VoLtage (note 1) @ 1ma V(BR) VoLts 1.3 Vwm VoLts PLC497 notes LC 1.0 maXimum ReVeRse Leakage CuRRent (note 1) @ Vwm id µa 20 maXimum CLamPing VoLtage (note 1) (Fig. 2) @ 8/20µs VC @ i PP 5.0V @ 5.0A maXimum woRking inVeRse BLoCking VoLtage (note 2) V wiB VoLts 75 inVeRse BLoCking Leakage CuRRent (note 2) @V wiB iR µa 1.0 maXimum CaPaCitanCe (note 3) @0V, 1mhz C pF 2.5 1.

FiguRe 2 - Common mode sensoR CiRCuit PRoteCtion CiRCuit BoaRd ReCommendations Circuit board layout is critical for electromagnetic compatibility protection. The following guidelines are recommended: • The protection device should be placed near the input terminals or connectors, the device will divert the transient current immediately before it can be coupled into the nearby traces. • The path length between the TVS device and the protected line should be minimized. • All conductive loops including power and ground loops should be minimized. • The transient current return path to ground should be kept as short as possible to reduce parasitic inductance. • Ground planes should be used whenever possible. For multilayer PCBs, use ground vias.
