TOSHIBA Photocoupler GaAAs IRed & Photo-IC
TLP115
High Speed, Long Distance Isolated Line Receiver Microprocessor System Interfaces Digital Isolation For A / D, D / A Conversion Computer-Peripheral Interfaces Ground Loop Elimination
The TOSHIBA mini flat coupler TLP115 is small outline coupler, suitable for surface mount assembly. TLP115 consists of a GaAAs light emitting diode, optically coupled to an integrated high gain, high speed shielded photo detector whose output is an open collector schottky clamped transistor. The shield, which shunts capacitively coupled common noise to ground, provides a guaranteed transient immunity specification of 1000V / s. * * * * * * Input current thresholds: IF=10mA (max.) Switching speed: 10MBd (typ.) Common mode transient immunity: 1000V / s (min.) Guaranteed performance over temp.: 0~70C Isolation voltage: 2500Vrms (min.) UL recognized: UL1577, file no.

Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook ("Handling Precautions"/"Derating Concept and Methods") and individual reliability data (i.e. reliability test report and estimated failure rate, etc).

(Note 4) Device considered a two-terminal device: Pins 1 and 3 shorted together, and pins 4, 5 and 6 shorted together. (Note 5) The VCC supply voltage to each TLP115 isolator must be bypassed by 0.1F capacitor. This can be either a ceramic or solid tantalum capacitor with good high frequency characterstic and should be connected as close as possible to package VCC and GND pins of each device. (Note 6) Maximum electrostatic discharge voltage for any pins: 180V(C=200pF, R=0)
