PSM712-LF-T7-JSM

PSM712-LF-T7 Transient Voltage Suppressor (TVS) Diode FEATURES transmission standard RS-485 applications. The PSM712-LF-T7 may be used to protect devices from transient voltages resulting from electrostatic discharge (ESD), electrical fast MACHANICAL DATA — SOT-23 package —Flammability Rating: UL 94V-0 —Terminal: Matte tin plated. —Packaging: Tape and Reel —High temperature soldering guaranted:260℃/10s —Reel size: 7 inch mi transients (FET), and lightning. The PSM712-LF-T7 features 400 Watts (tp=8/20 μs) of power handling capability to accommodate the higher transient voltage levels which may be expected in extended common mode applications. This provides higher equipment reliability and eliminates the “ guess work” required when using zener diodes that are not rated to handle such transient conditions. The integrated design aids in reducing voltage over-shoot associated with trace inductance. The low clamping voltage of the PSM712-LF-T7 minimizes the stress on the protected transceiver. The SOT-23 package allows flexibility in the design of “crowed” circuit boards. or to -7V) protection in multi-point data ct (TVS) diode is designed for asymmetrical (12V — 400 watts peak pulse power (tp=8/20μs) — Transient protection for asymmetrical data lines to IEC 61000-4-2 (ESD) ±15kV(air), ±8kV(contact) IEC 61000-4-4 (FET) 40A (5/50ns) IEC 61000-4-5 (Lightning) 12A (8/20μs) —Protects two +12V to -7V lines —Low capacitance —Low leakage current —Low clamping voltage —Solid-state silicon avalanche technology —RoHS compliant du The PSM712-LF-T7 transient voltage suppressor co n DESCRIPTION O —Device:PSM712-LF-T7 —Package:SOT-23 —Marking:712 —Material: Halogen free —Packing: Tape & Reel Quantity per reel: 3,000pcs Se ORDERING INFORMATION D S G Schematic diagram MI CR SOT-23 top view APPLICATIONS JS —Protection of RS-485 transceivers with extended common-mode range —Security systems —Automatic Teller Machines —HFC systems — Networks www.jsmsemi.com 第１页，共４页 PSM712-LF-T7 Transient Voltage Suppressor (TVS) Diode ABSOLUTE MAXIMUM RATING Symbol Parameter Value Units Peak Pulse Power (8/20μs) 400 W IPP Peak Pulse Current (8/20μs) 17 A VESD ESD per IEC 61000-4-2 (Air) ESD per IEC 61000-4-2 (Contact) ±15 ±8 kV TOPT Operating Temperature -55/+150 °C TSTG Storage Temperature -55/+150 °C ELECTRICAL CHARACTERISTICS (Tamb=25°C) Parameter Test Condition IR VC1 Clamping Voltage 1 VC2 Clamping Voltage 2 IT = 1mA Max Min Typ 12 13.3 Units Max 7 7.5 V V VR = VRWM 1 20 μA IPP = 5A, tp = 8/20μs 20 10 V IPP = 17A, tp = 8/20μs 26 12 V 75 75 pF O VR = 0V, f = 1MHz VR = VRWM, f = 1MHz 45 45 pF JS MI CJ2 Junction Capacitance 1 Junction Capacitance 2 CR CJ1 Pin 3 to 1 or Pin 2 to 1 mi VBR Reverse Working Voltage Reverse Breakdown Voltage Reverse Leakage Current Se VRWM Typ co n Min Pin 3 to 1 and Pin 3 to 2 (7V TVS) du Symbol Pin 1 to 3 and Pin 2 to 3 (12V) TVS ct or PPP www.jsmsemi.com 第２页，共４页 PSM712-LF-T7 Transient Voltage Suppressor (TVS) Diode JS MI CR O Se mi co n du ct or ELECTRICAL CHARACTERISTICS CURVE www.jsmsemi.com 第３页，共４页 PSM712-LF-T7 Transient Voltage Suppressor (TVS) Diode Package Outline SOT-23 JS MI CR O Se mi co n du ct or Dimensions in mm www.jsmsemi.com 第４页，共４页
