Circuit

PTD615-1, PTD615-2, PTD615-3
OPTICALLY COUPLED ISOLATORS
Outline Dimension: Unit: Inch (mm)

Features

1. High Voltage Isolation.
2. High Current Transfer Ratio.
PTD615-1: 40 - 80%
PDT615-2: 63 - 125%
PTD615-3: 100 - 200%
3. Low Cost Dual-In-Line Package.
4. Dual Configuration.

The PTD615 series are optically coupled isolators. Each channel consists of a Gallium Arsenide infrared emitting diode:
and an NPN silicone phototransistor mounted in a standard 6-pin dual-in-line package.
The PTD615 series offers two channels per unit.
All electrical parameters are 100% tested by manufacturing. Specifications are guaranteed to a cumulative .65% AQL
