HCPL-T250#300

Isolators - Gate Drivers Overview

The HCPL-T250#300 is a logic output optocoupler designed for IGBT gate drive applications. It features a single channel with an open collector output type and operates within a temperature range of -20°C to +85°C. The device provides an isolation voltage of 3750 Vrms and supports a maximum continuous output current of 1.5 A. Key electrical parameters include a forward current of 16 mA, forward voltage of 1.8 V, reverse voltage of 5 V, and power dissipation of 250 mW. It utilizes a surface mount DIP-8 gull wing package.

Isolators - Gate Drivers Feature Summary

• Integrated GaAs LED coupled to an integrated circuit with a power output stage specifically engineered for driving power IGBTs and MOSFETs in motor control inverters.
• Provides high common-mode rejection (CMR) capability of 8 kV/µs at VCM = 1,500 V to ensure signal integrity in noisy environments.
• Features a wide supply voltage range of 15 V to 35 V, allowing direct driving of IGBTs up to 1,200 V/25 A specifications.

Isolators - Gate Drivers Applications

• IGBT and MOSFET gate drive circuits
• AC and brushless DC motor drivers
• Industrial inverters and motor control systems

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix #300 indicates the surface-mount gull-wing package variant distinct from through-hole versions. Confirm RoHS compliance status as indicated by the 'E' suffix in related datasheets, though the provided model lacks it. Ensure the supplier source matches Broadcom Limited or authorized Avago distributors to guarantee authenticity and traceability for industrial safety certifications.

Isolators - Gate Drivers Selection Notes

Select this component when high current drive capability (1.5 A) is required for direct IGBT/MOSFET switching without external discrete driver stages. Consider the 3750 Vrms isolation rating for primary-side sensing or control separation. Evaluate the surface-mount footprint requirements against PCB layout constraints compared to the through-hole HCPL-T250-000E variant.

Isolators - Gate Drivers Part Context

This device belongs to the HCPL series of logic output optocouplers manufactured by Broadcom Limited (formerly Avago). It is part of a family of gate driver isolators designed to replace traditional transformer-based or discrete driver solutions in high-power conversion applications. The series emphasizes compact integration of optical coupling and power output stages.

Isolators - Gate Drivers Replacement Considerations

The HCPL-T250-000E serves as a through-hole equivalent with identical electrical characteristics but different packaging. For surface-mount replacements, verify pinout compatibility with other 8-pin DIP gate driver optocouplers from the same manufacturer family, ensuring isolation voltage and output current ratings meet or exceed the original design requirements.
