Overview
Description
The PS9117A is an optically coupled high-speed, active low type isolator containing an AlGaAs LED on the input side and a photodiode and a signal processing circuit on the output side on one chip. The PS9117A is designed specifically for high common mode transient immunity (CMR) and low pulse width distortion. The PS9117A is suitable for high density application.
Features
- Pulse width distortion (|tPHL - tPLH| = 35 ns MAX.)
- High common mode transient immunity (CMH, CML = ±15 kV/μs MIN.)
- Small package (SO-5)
- High-speed (10 Mbps)
- High isolation voltage (BV = 3 750 Vr.m.s.)
- Open collector output
- Ordering number of taping product: PS9117A-F3 : 2 500 pcs/reel
- Pb-Free product
- Safety standards UL approved: UL1577, Single protection CSA approved: CAN/CSA-C22.2 No. 62368-1, Basic insulation VDE approved: DIN EN 60747-5-5 (Option)

What parameter of electrical specification can the life be estimated?
... degrades, its output no longer changes from high to low, even when a current higher than IFHL defined by the specification flows. By this phenomenon, the life of the photocoupler can be judged as having expired. For details, contact your nearest distributor. [Example in Electrical Specifications of PS9117A Data Sheet]

Why the CTR characteristic is not listed in high speed photocoupler?
The PS9117A has a function for outputting a digital signal (H/L). The relationship between the input and the output with regard to transmission of this signal is shown in the following truth table. To change the output from "H" to "L" here, it is necessary to flow an ...

What is pulse width distortion (|tPHL - tPLH |)?
... the lower the value of |tPHL - tPLH| is, the less distorted the photocoupler is, i.e., the less its pulse width changes. [Propagation delay time and test circuit in the PS9117A data sheet] Related FAQ:What are propagation delay time (H → L) tPHL and propagation delay time (L → H) tPLH?
