HCPL-3120#300

Isolators - Gate Drivers Overview

The HCPL-3120#300 is a logic output optocoupler designed for IGBT gate drive applications. It features a single channel with an open collector output and operates within a temperature range of -40°C to +100°C. The device provides 3750 Vrms isolation voltage and supports a maximum forward current of 16 mA with a forward voltage of 1.8 V. Key timing parameters include a typical rise/fall time of 100 ns and a maximum propagation delay of 500 ns. It is housed in an 8-pin DIP Gull Wing package through-hole mounting style.

Isolators - Gate Drivers Feature Summary

• Integrated high-current output stage capable of driving IGBTs directly
• High common mode transient immunity for reliable operation in noisy environments
• Optimized switching speed with low propagation delay

Isolators - Gate Drivers Applications

• Industrial inverter systems
• Motor control variable frequency drives
• Switching power supplies

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix #300 indicates the non-RoHS compliant version in tube packaging as per official documentation. Confirm that the 8-pin DIP Gull Wing package matches the target PCB footprint. Ensure the 3750 Vrms isolation rating meets the safety requirements of the final equipment design. Cross-reference the manufacturer part number with the distributor listing to avoid confusion with RoHS-compliant variants.

Isolators - Gate Drivers Selection Notes

Select this component when direct IGBT gate driving capability is required without external discrete transistors. The open collector output configuration necessitates appropriate pull-up resistor selection based on the target gate voltage. Consider the thermal dissipation limits of 295 mW during continuous operation. Verify compatibility with the input LED drive circuitry regarding the 16 mA maximum forward current constraint.

Isolators - Gate Drivers Part Context

This part belongs to the HCPL series of logic output optocouplers manufactured by Broadcom Limited. It is specifically engineered for power electronics applications requiring galvanic isolation between control circuits and high-power switches. The #300 suffix denotes the specific packaging and compliance status distinct from other series variants.

Isolators - Gate Drivers Replacement Considerations

Check for HCPL-3120-300E as a potential RoHS-compliant alternative if regulatory changes require it, noting that pinout and electrical characteristics should be verified against the datasheet.
