The following models can be replaced

Low cost single light receiving chip element TLP175A

Trait:  

· Low trigger LED current IFT=1mA

· High cost performance (from the original 3chip configuration to 1chip configuration!)

The 4-pin SO6 package enables a photorelay with low trigger LED current

TLP170AM, TLP170GM

By increasing the sensitivity of the photodiode array, the maximum triggered LED current reaches 1 mA, reducing the input side power loss. Therefore, by using it as a battery-operated safety device and an on/off control output for various sensors, it helps to reduce the power consumption and long-term operation of the device.

Trait:

· Low trigger LED current :IFT=1mA(max)

· Small package: 4-pin SO6

· High insulation voltage :BVs=3750Vrms(min)

Trait:

Use：

· Safety system - Passive sensor (PIR[Note 1])

· Industrial equipment

· Programmable logic controller, I/O interface, various sensor control

· Building automation system

· Replace various mechanical relays

[Note 1]PIR (Passive infrared) : A sensor that detects a person's proximity by changes in ambient infrared radiation

Summarize:

A: Output pin spacing >1.5 mm

(compliant with @IEC61010-1)

B: Input and output pin spacing > 0.5mm

(Better weldability)

Note) There are no plans to obtain UL, cUL and other safety standards certification.

Products need to be treated in accordance with hygroscopic Management Level 3 (JEDEC) to obtain moisture-proof packaging.
