SFH615A-1X016

Overview

The SFH615A-1X016 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output and is housed in a PDIP-4 through-hole package. The device provides an isolation voltage of 5300 Vrms. Key electrical parameters include a minimum forward current (If) of 60 mA, a typical forward voltage (Vf) of 1.65 V, and a maximum collector-emitter voltage (Vceo) of 70 V. The current transfer ratio ranges from 40% to 80%. Maximum collector current is 50 mA with a saturation voltage of 400 mV. Switching characteristics specify a rise time of 2 µs and a fall time of 11 µs. The component operates within a temperature range of -55°C to +100°C and has a power dissipation rating of 150 mW.

Feature Summary

• Provides high-voltage isolation capability suitable for separating circuits with significant potential differences.
• Features a standard four-pin DIP package designed for reliable through-hole mounting on printed circuit boards.
• Utilizes an NPN phototransistor output stage for efficient signal transmission across the isolation barrier.

Applications

• Industrial control systems requiring galvanic isolation
• Solid-state relay driver circuits
• Microcontroller interface isolation

Procurement Notes

Verify that the specific suffix X016 corresponds to the tube packaging format as indicated in distributor specifications. Confirm that the required current transfer ratio falls within the 40% to 80% range defined for this variant. Ensure that the procurement source provides official datasheets to validate the 5300 Vrms isolation rating and thermal performance limits before integration into final designs.

Selection Notes

Select this component when a single-channel isolation solution with moderate speed and high voltage ratings is required. The PDIP-4 form factor is appropriate for legacy or space-permissive through-hole designs. Consider the 40-80% CTR range for logic level interfacing. Evaluate the 2 µs rise time against system timing requirements to ensure adequate signal integrity for the intended application frequency.

Part Context

This part belongs to the SFH615A series of transistor output optocouplers. The series is characterized by low coupling capacitance and high isolation voltage options. The SFH615A-1X016 specifically denotes the DIP package variant with a defined current transfer ratio binning. It serves as a fundamental building block for basic digital isolation tasks in electronic systems.

Replacement Considerations

The VO615A-1 is listed as a recommended alternative with identical pinout and similar electrical characteristics. Verify that the replacement maintains the same 5300 Vrms isolation rating and compatible CTR specifications for direct substitution in existing designs.
