Overview
The EL3H7(J)(EA)-G is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features an NPN phototransistor output and provides high isolation voltage of 3750 Vrms between input and output circuits. The device operates within a temperature range of -55°C to +110°C and is housed in a compact 4-pin SSOP package. Key electrical parameters include a maximum collector-emitter voltage of 80V, a maximum forward current of 50mA, and a power dissipation rating of 200mW.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits
- Utilizes an NPN phototransistor for signal transmission
- Designed for surface mount installation in compact form factors
Applications
- Industrial control systems requiring galvanic isolation
- Signal interfacing between microcontrollers and high-voltage loads
- Power supply feedback loops for noise immunity
Procurement Notes
Verify the specific CTR bin designation associated with the (J) suffix against the manufacturer's latest datasheet to ensure compatibility with circuit gain requirements. Confirm RoHS compliance status and packaging format details directly with authorized distributors prior to ordering.
Selection Notes
Select this component when high isolation voltage and wide operating temperature ranges are required. Ensure the NPN output configuration aligns with the load interface design. Verify that the SSOP package dimensions fit the available PCB real estate constraints.
Part Context
This part belongs to the EL3H7 series of transistor output optocouplers from Everlight Electronics. The series is characterized by its small outline package options and robust isolation capabilities, suitable for general-purpose digital signal isolation applications in consumer and industrial electronics.
Replacement Considerations
Check for direct pin-compatible substitutes within the same family, such as EL3H7(A)-G or EL3H7(C)-G, ensuring identical isolation ratings and output transistor characteristics before substitution.
