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 1 Peak Power Dissipation of 500W 8/20µs Maximum Capacitance of 5.0pF at 0Vdc 1MHz Line-to-Ground I/O2 3 VREF 4 2 I/O1 1 GND Maximum Leakage Current of 1µA @ 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) SOT143 APPLICATIONS RS422 Interface LAN/WLAN Access Point terminals Industrial control communication ports I 2C Bus Protection S12 Marking Code: MAXIMUM RATINGS Tj = 25°C Unless otherwise noted Rating Symbol Value Units Peak Pulse Power (8/20µs Waveform) P PPM 500 W Peak Pulse Current (8/20µs Waveform) I PP 16 A Operating Junction Temperature Range TJ -55 to +125 °C Storage Temperature Range Tstg -55 to +150 °C Soldering Temperature, t max = 10s TL 260 °C 10/6/2006 Page 1 www.panjit.com PJSR12 ELECTRICAL CHARACTERISTICS Parameter Tj = 25°C unless otherwise noted Min Conditions Symbol Typical Max Units 12 V VWRM Reverse Stand-Off Voltage Reverse Breakdown Voltage VBR I BR = 1mA Reverse Leakage Current IR VR = 12V Clamping Voltage (8/20µs) Vc Clamping Voltage (8/20µs) 13.3 V 1 µA I pp = 5A 22 V Vc I pp = 10A 27 V Clamping Voltage (8/20µs) Vc I pp = 16A 31 V Off State Junction Capacitance Cj 0 Vdc Bias f = 1MHz Between I/O pins and GND 3.8 5 pF 0 Vdc Bias f = 1MHz Between I/O pins 1.4 3 pF TYPICAL CHARACTERISTIC CURVES Surge Pulse Waveform Definition Maximum Clamping Voltage vs Ipp 8/20µs 35 110 100 90 80 70 60 50 40 30 20 10 0 Clamping voltage, V Percent of Ipp Pulse Waveform 50% of Ipp @ 20µs Rise time 10-90% - 8µs 30 25 20 15 0 5 10 15 20 25 30 5 7 9 tim e, µsec 11 13 15 Ipp, A (8/20µsec) Line to Ground Capacitance 5 Capacitance, pF 4 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 © Copyright PanJit International, Inc 2006 The information presented in this document is believed to be accurate and reliable.
