HCPL-814-W6AE

Transistor, Photovoltaic Output Optoisolators Overview

The HCPL-814-W6AE is a single-channel transistor output optocoupler manufactured by Broadcom Limited. It features an internal phototransistor coupled to two parallel, reverse-connected light-emitting diodes, enabling direct AC input drive without external rectification. The device provides a high isolation voltage of 5000Vrms and operates within a temperature range of -30°C to +100°C. Key electrical parameters include a maximum collector-emitter saturation voltage of 200mV, a maximum forward current of 50mA, and a typical rise/fall time of 4µs/3µs. It is housed in a 4-DIP package with a 0.300-inch (7.62mm) pin spacing.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'W6AE' against official Broadcom documentation to confirm lead-free status and RoHS compliance requirements. Ensure the ordering part number matches the required packaging format, as suffixes often dictate tube or tape-and-reel configurations. Cross-reference the manufacturer's latest datasheet to validate environmental certifications and operating temperature ranges before finalizing procurement specifications.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when direct AC input driving capability is required to simplify circuit design by eliminating external rectifiers. Consider the 5000Vrms isolation rating for safety-critical applications requiring strong barrier protection. Evaluate the 50mA output current capacity and 200mV saturation voltage to ensure compatibility with downstream logic levels and load requirements.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the HCPL-814 series of transistor output optocouplers from Broadcom. The series is characterized by its ability to handle AC inputs directly due to the dual LED structure. Other variants in the family may differ in packaging options, such as surface mount devices, or specific certification approvals, but share the core functional architecture of AC-compatible optical isolation.
