HCPL-3700#300

Transistor, Photovoltaic Output Optoisolators Overview

The HCPL-3700#300 is a voltage and current threshold detection optocoupler designed for AC-to-DC logic interface applications. It features an open collector output capable of handling a maximum continuous output current of 30 mA. The device provides high isolation with a rated insulation voltage of 3750 Vrms. It operates within a temperature range of -40°C to +85°C and utilizes a surface mount 8-SMD, Gull Wing package. Key electrical parameters include a maximum forward current of 50 mA, a typical rise time of 20 μs, and a fall time of 300 ns.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Integrated voltage and current threshold detection capabilities for direct signal processing
• Open collector output configuration suitable for interfacing with various logic families
• High-voltage isolation barrier ensuring safety between AC input and DC logic sides

Transistor, Photovoltaic Output Optoisolators Applications

• AC-to-DC logic interface circuits
• Intelligent Power Module (IPM) control systems
• Industrial networking systems requiring isolated threshold sensing

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix #300 confirms the surface mount 8-SMD Gull Wing package variant, as other suffixes may indicate through-hole DIP packaging. Confirm RoHS compliance status, as some sources indicate non-compliance for standard versions. Ensure the supplier documentation matches the required operating temperature range of -40°C to +85°C for your specific application environment.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when direct threshold detection is required without external comparators. The open collector output allows flexible pull-up voltage selection. Consider the 20 μs rise time limitation for high-frequency applications; faster variants like the HCPL-3120 series are available if sub-microsecond switching is necessary. Verify that the 30 mA output current capability meets the load requirements of the downstream logic circuit.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the Broadcom HCPL series of optocouplers, which are widely used in industrial and power electronics. The HCPL-3700 specifically addresses the need for integrated threshold detection, simplifying designs that monitor AC line conditions or motor currents. It serves as a bridge between high-voltage AC domains and low-voltage digital control systems.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

The HCPL-3700-000E is a pin-compatible alternative but typically uses a through-hole DIP-8 package rather than surface mount. For surface mount replacements with similar functionality, verify availability of the HCPL-3700#300 from authorized distributors. No direct drop-in SMD substitutes with identical threshold characteristics are publicly confirmed.
