HCPL-J312-500E

Isolators - Gate Drivers Overview

The HCPL-J312-500E is a logic output optocoupler featuring an integrated IGBT gate driver. It provides a peak output current of 2.5 A and supports a supply voltage range of 15 V to 30 V. The device offers a high common-mode transient immunity (CMTI) of at least 15 kV/µs at VCM = 1500 V. Electrical characteristics include a typical rise/fall time of 100 ns, a maximum propagation delay of 500 ns, and a maximum forward current of 16 mA. It operates within a temperature range of -40°C to +100°C and includes under-voltage lockout (UVLO) with hysteresis.

Isolators - Gate Drivers Feature Summary

• Integrated power output stage capable of directly driving IGBTs and MOSFETs without requiring negative gate drive.
• High common-mode transient immunity ensures reliable operation in noisy environments with fast switching edges.
• Built-in under-voltage lockout protection prevents improper device operation during low supply conditions.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix '500E' corresponds to the surface-mount Gull Wing package configuration. Confirm that the component meets the required insulation standards for your application, such as UL 1577 or VDE 0884. Ensure the ordering documentation explicitly lists the tape-and-reel packaging format associated with this suffix.

Isolators - Gate Drivers Selection Notes

Select this component when direct gate drive capability is required for IGBTs up to 1200V. It is suitable for applications demanding high isolation voltage and fast switching speeds. Consider the surface-mount package for PCB space constraints. Verify that the input current requirements align with the source logic levels.
