| PJSR12 Low Capacitance TVS and Diode Array This diode array is configured to protect up to two data transmission lines acting as a line terminator, minimizing overshoot and undershoot conditions due to bus impedance as well as protect against over-voltage events as electrostatic discharges. Additionaly the TVS Device offers overvoltage transient protection between the operating voltage bus and ground plane. 3 4 2 SPECIFICATION FEATURES Peak Power Dissipation of 500W 8/20s Maximum Capacitance of 5.0pF at 0Vdc 1MHz Line-to-Ground Maximum Leakage Current of 1A @ VRWM Industry Standard SMT Package SOT143 IEC61000-4-2, IEC61000-4-4 and IEC61000-4-5 Full Compliance 100% Tin Matte finish (LEAD-FREE PRODUCT) VREF 4 I/O2 3 1 2 I/O1 1 GND APPLICATIONS RS422 Interface LAN/WLAN Access Point terminals Industrial control communication ports I 2C Bus Protection SOT143 Marking Code: S12 MAXIMUM RATINGS Tj = 25C Unless otherwise noted Rating Peak Pulse Power (8/20s Waveform) Peak Pulse Current (8/20s Waveform) Operating Junction Temperature Range Storage Temperature Range Soldering Temperature, t max = 10s Symbol P PPM I PP TJ Tstg TL Value 500 16 -55 to +125 -55 to +150 260 Units W A C C C 10/6/2006 Page 1 www.panjit.com PJSR12 ELECTRICAL CHARACTERISTICS Parameter Reverse Stand-Off Voltage Reverse Breakdown Voltage Reverse Leakage Current Clamping Voltage (8/20s) Clamping Voltage (8/20s) Clamping Voltage (8/20s) Off State Junction Capacitance Symbol VWRM VBR IR Vc Vc Vc Cj I BR = 1mA VR = 12V I pp = 5A I pp = 10A I pp = 16A 0 Vdc Bias f = 1MHz Between I/O pins and GND 0 Vdc Bias f = 1MHz Between I/O pins Tj = 25C unless otherwise noted Conditions Min Typical Max 12 13.3 1 22 27 31 3.8 1.4 5 3 Units V V A V V V pF pF TYPICAL CHARACTERISTIC CURVES Surge Pulse Waveform Definition Pulse Waveform 110 100 90 80 70 60 50 40 30 20 10 0 0 Maximum Clamping Voltage vs Ipp 8/20s 35 Clamping voltage, V Percent of Ipp 50% of Ipp @ 20s 30 25 Rise time 10-90% - 8s 20 15 5 10 15 tim e, sec 20 25 30 5 7 9 11 13 15 Ipp, A (8/20sec) Line to Ground Capacitance 5 4 Capacitance, pF 3 2 1 0 0 2 4 6 8 10 12 Bias Voltage, Vdc 10/6/2006 Page 2 www.panjit.com PJSR12 PACKAGE DIMENSIONS - SOT143 (c) Copyright PanJit International, Inc 2006 The information presented in this document is believed to be accurate and reliable.
