IR21064STR Gate Driver IC - Equivalent & Substitute Parts

Part Overview

The IR21064STR is a high-side or low-side gate driver IC manufactured by Infineon Technologies, designed for driving IGBT and N-Channel MOSFET gates in power management applications. This component operates with independent dual-channel configuration and supports bootstrap voltage up to 600V. The IR21064STR is classified as obsolete, making identification of active equivalent parts essential for new designs and production continuity. The IR21064STRPBF serves as the direct active substitute, offering identical electrical and mechanical specifications with current manufacturing status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IR21064STR with IR21064STRPBF is based on strict electrical and mechanical parameter equivalence. Both parts share identical specifications across all critical functional parameters: dual independent gate driver channels, IGBT and N-Channel MOSFET gate type support, 10V-20V supply voltage range, 200mA/350mA peak output current ratings, 600V bootstrap voltage capability, and 14-SOIC surface mount packaging. The substitution is valid because all allowed electrical parameters (supply voltage, logic levels, output current, rise/fall times, operating temperature) and mechanical parameters (package type, pin configuration) are identical between the two part numbers. The primary distinction is product status and compliance certification: IR21064STR is obsolete, while IR21064STRPBF is active production with RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

The IR21064STRPBF is the direct substitute for IR21064STR based on complete electrical and mechanical parameter equivalence. Selection of IR21064STRPBF is recommended for all new designs and production applications due to active product status and RoHS3 compliance certification. The obsolete status of IR21064STR necessitates transition to IR21064STRPBF for supply chain continuity and regulatory compliance in markets requiring RoHS certification. Both parts are manufactured by Infineon Technologies and maintain identical functional specifications, ensuring drop-in compatibility at the circuit level. The MSL rating difference (MSL 1 vs MSL 3) reflects manufacturing process updates in the active part; IR21064STRPBF requires standard moisture control during storage and handling per IPC-A-610 guidelines for MSL 3 components.
