ISL6208CB-T Half-Bridge Gate Driver IC Equivalent & Substitute Parts

Part Overview

The ISL6208CB-T is a half-bridge gate driver IC manufactured by Renesas Electronics Corporation, designed for driving N-channel MOSFETs in synchronous half-bridge configurations. This device operates with a 4.5V to 5.5V supply voltage and delivers 2A peak output current for both source and sink operations.

The ISL6208CB-T carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term production requirements for applications utilizing this gate driver topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISL6208CB-T is determined by strict equivalence across the following critical parameters:

• Driven configuration (half-bridge topology)
• Number of drivers (2 channels)
• Gate type (N-channel MOSFET)
• Supply voltage range (4.5V ~ 5.5V)
• Peak output current specifications (2A source, 2A sink)
• Bootstrap voltage rating (33V maximum)
• Switching characteristics (8ns rise/fall time)
• Package type (8-SOIC form factor)
• Operating temperature range (-10°C ~ 125°C)
• Input logic configuration (non-inverting)

The ISL6208CBZ-T meets all these criteria and qualifies as a direct substitute. Both parts share identical electrical specifications and mechanical packaging, with the primary distinction being product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The ISL6208CBZ-T is the direct substitute for the ISL6208CB-T based on complete electrical and mechanical equivalence. Selection between these parts should be driven by the following factors:

Product Status: The ISL6208CB-T is obsolete, while the ISL6208CBZ-T maintains active product status with ongoing manufacturer support and availability.

Compliance Requirements: The ISL6208CBZ-T is ROHS3 compliant, whereas the ISL6208CB-T is RoHS non-compliant. Applications subject to RoHS directives or customer specifications requiring RoHS compliance must use the ISL6208CBZ-T.

Moisture Sensitivity: The ISL6208CB-T carries MSL 1 (unlimited moisture sensitivity level), while the ISL6208CBZ-T is rated MSL 3 (168 hours). MSL 3 requires controlled storage and handling within 168 hours of package opening. Applications with extended shelf storage or high-humidity environments may benefit from the ISL6208CB-T's lower MSL rating, though the ISL6208CBZ-T remains suitable for standard manufacturing environments with proper moisture control.

Supply Availability: The ISL6208CBZ-T offers significantly higher inventory availability (55,300 pcs) compared to the ISL6208CB-T (924 pcs), supporting sustained production requirements.

For new designs and ongoing production, the ISL6208CBZ-T is the recommended selection due to active product status, RoHS compliance, and supply reliability.

Frequently Asked Questions (FAQ)

Q: Can the ISL6208CBZ-T be used as a direct replacement for the ISL6208CB-T in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including supply voltage, output current, switching characteristics, and package form factor. No circuit modifications are required for substitution.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: Obsolete status indicates the ISL6208CB-T is no longer in active production. The ISL6208CBZ-T, with active status, receives ongoing manufacturer support, updated documentation, and guaranteed supply continuity. For long-term production programs, active-status parts provide superior supply chain reliability.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical function. Both parts deliver identical electrical performance. RoHS compliance becomes a requirement only when mandated by customer specifications, regional regulations, or design standards.

Q: What does MSL 3 (168 Hours) mean for the ISL6208CBZ-T?

A: MSL 3 specifies that the component must be used within 168 hours of package opening in a controlled moisture environment. This is standard for modern surface-mount components and is managed through proper storage in dry cabinets or moisture-barrier packaging. Standard manufacturing environments with moisture control easily accommodate this requirement.

Q: Are there any pin-to-pin or footprint differences between these parts?

A: No. Both parts use the 8-SOIC package with identical pin assignments and PCB footprint dimensions (0.154" width, 3.90mm). PCB layouts and assembly processes require no modification.

Q: Which part should be selected for new designs?

A: The ISL6208CBZ-T is the appropriate selection for new designs due to active product status, RoHS3 compliance, and superior supply availability. This ensures design longevity and manufacturing continuity.
