HCPL-5301#100

Logic Output Optoisolators Overview

The HCPL-5301#100 is a high-reliability logic output optocoupler manufactured by Broadcom Limited. It features an open collector output with Schottky clamping, designed for power module and gate drive interfaces. The device provides 1500 VDC isolation voltage and operates within a temperature range of -55°C to +125°C. Key electrical parameters include a maximum propagation delay of 750 ns, a minimum pulse width distortion (PWD) of 450 ns at IF=10mA, and a current transfer ratio (CTR) exceeding 30%. It supports a continuous output current of 15 mA and dissipates up to 145 mW. The component is housed in an 8-DIP Trimmed package.

Logic Output Optoisolators Procurement Notes

Verify that the specific suffix #100 corresponds to the 8-DIP Trimmed hermetically sealed variant. Confirm compliance with MIL-PRF-38534 Class H standards if military-grade reliability is required. Ensure the procurement channel sources units from authorized Broadcom production lines to guarantee authenticity and traceability. Check for specific lead finish options such as gold-plated or solder-dipped leads based on assembly requirements.

Logic Output Optoisolators Selection Notes

Select this component when high-speed switching with minimal pulse width distortion is critical for power electronics. The integrated Schottky clamp reduces storage time, making it suitable for high-frequency gate driving. Consider the 1500 VDC isolation rating for safety-critical industrial and aerospace environments. Verify that the 8-DIP Trimmed package fits the available PCB footprint and that the operating temperature range meets the environmental constraints of the target application.

Logic Output Optoisolators Part Context
