HCPL-3150

Isolators - Gate Drivers Overview

The HCPL-3150 is a single-channel IGBT gate drive optocoupler manufactured by Broadcom Limited. It integrates an infrared LED with an integrated circuit featuring a power output stage to provide electrical isolation for driving power devices. The device delivers a minimum peak output current of 0.5A and supports a supply voltage range of 15V to 30V. Key electrical specifications include a maximum propagation delay of 0.5μs, a common-mode rejection ratio (CMR) of 15kV/μs at VCM=1500V, and a low-level output voltage of 1.0V maximum. It operates within a temperature range of -40°C to +100°C and offers an insulation voltage of 3750 Vrms.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix code on the component marking to confirm the package type and reel/tube configuration, as variations exist within the HCPL-3150 family. Ensure the procurement source provides valid UL, CSA, and IEC safety certification documents corresponding to the requested variant. Cross-reference the manufacturer part number with official Broadcom datasheets to confirm compatibility with system isolation requirements before finalizing orders.

Isolators - Gate Drivers Selection Notes

Select this component when direct gate drive capability for IGBTs or MOSFETs is required without external discrete drivers. Consider the 0.5A peak current rating against the target power device's gate charge requirements. Evaluate the 15kV/μs CMR specification against the expected common-mode transient noise levels in the application environment to ensure signal integrity.
