HCPL-2602

Overview

The HCPL-2602 is a high common-mode rejection (CMR) optically coupled line receiver manufactured by Broadcom Limited. It integrates a GaAsP light-emitting diode, an input current regulator, and a Schottky-clamped transistor output within a single package. The device provides electrical isolation with a rated insulation voltage of 3750 Vrms. Key performance parameters include a data rate of 10 Mb/s, a maximum forward current of 60 mA, and a typical forward voltage of 2.7 V. The output stage features an open collector configuration with Schottky clamping to minimize storage time. Transition times are specified with a typical rise time of 24 ns and a fall time of 10 ns. The component supports through-hole mounting in an 8-pin DIP package.

Feature Summary

• Integrates a GaAsP LED, input current regulator, and Schottky-clamped transistor for optimized switching speed.
• Provides high common-mode transient immunity suitable for noisy industrial environments.
• Features an open-collector output design that facilitates direct interfacing with logic circuits.

Applications

• Industrial process control systems requiring signal isolation
• Solid-state relay driver circuits
• Logic interface between isolated digital grounds

Procurement Notes

Verify the specific ordering suffix to confirm package type and tape/reel specifications, as variations exist between standard DIP and surface-mount configurations. Confirm availability status, as certain variants may be discontinued or subject to supply constraints. Ensure the selected part number matches the required lead time and shipping restrictions for the target region. Cross-reference the manufacturer's latest documentation to validate compliance with current RoHS directives and environmental standards before finalizing procurement orders.

Selection Notes

Select this component when high-speed digital isolation is required alongside robust noise immunity. The integrated current regulator simplifies drive circuit design by reducing sensitivity to LED forward voltage variations. The Schottky clamp on the output transistor ensures fast turn-off characteristics, making it suitable for applications demanding rapid signal transitions. Consider the operating temperature range and power dissipation limits when designing thermal management strategies for enclosed enclosures.

Part Context

The HCPL-2602 belongs to the HCPL-26xx series of high CMR line receiver optocouplers. This family is designed to provide reliable signal transmission across isolation barriers while maintaining signal integrity in electrically noisy environments. The device complements other isolators in the portfolio by offering a balance of speed and simplicity, targeting applications where standard optocouplers lack sufficient common-mode rejection capabilities.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the available documentation. Verify compatibility with existing footprints and electrical requirements if considering alternative manufacturers. Check for pinout similarities and matching isolation voltage ratings when evaluating potential replacements.
