IR2304 Half-Bridge Gate Driver IC - Equivalent & Substitute Parts

Part Overview

The IR2304 is a half-bridge gate driver IC designed for driving IGBT and N-Channel MOSFET configurations in power management applications. This non-inverting driver operates with independent channels and is housed in an 8-PDIP package. The IR2304 is classified as obsolete, making identification of active equivalent parts essential for new designs and production continuity. The IR2304PBF serves as the direct active substitute, maintaining identical electrical and mechanical specifications while offering current production availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IR2304 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part IR2304PBF maintains identical specifications in the following key areas:

• Driven configuration (half-bridge topology)
• Channel type and number of independent drivers (2 channels)
• Gate type compatibility (IGBT and N-Channel MOSFET)
• Supply voltage operating range (10V ~ 20V)
• Logic voltage thresholds (VIL 0.8V, VIH 2.3V)
• Peak output current ratings (source 60mA, sink 130mA)
• Input signal type (non-inverting)
• Bootstrap voltage rating (600V maximum)
• Rise and fall time characteristics (200ns rise, 100ns fall)
• Operating temperature range (-40°C ~ 150°C)
• Physical package and mounting (8-DIP through-hole, 0.300" / 7.62mm)

The IR2304PBF is classified as an active product, whereas the IR2304 is obsolete. This substitution represents a direct replacement with no functional or performance differences.

Parameter Comparison

Engineering Selection Recommendations

The IR2304PBF is the direct equivalent for the obsolete IR2304. Selection of the IR2304PBF is appropriate for all applications currently using or designed for the IR2304, as it maintains complete electrical and mechanical compatibility. The active product status of the IR2304PBF ensures ongoing availability and supply chain continuity. Both parts share identical export classifications (ECCN EAR99) and tariff codes (HTSUS 8542.39.0001), simplifying procurement and regulatory compliance. No design modifications or board-level changes are required when transitioning from IR2304 to IR2304PBF.

Frequently Asked Questions (FAQ)

Q: Can IR2304PBF be used as a direct replacement for IR2304?

A: Yes. The IR2304PBF is electrically and mechanically identical to the IR2304. All electrical parameters, including supply voltage, output current, timing characteristics, and operating temperature range, are equivalent. The 8-DIP through-hole package dimensions are identical, allowing direct PCB substitution without layout modifications.

Q: Why is the IR2304 listed as obsolete?

A: The IR2304 has been discontinued by the manufacturer. The IR2304PBF represents the active production equivalent and should be used for new designs and ongoing production requirements.

Q: Are there any differences in RoHS or REACH compliance between IR2304 and IR2304PBF?

A: The IR2304 is listed as RoHS non-compliant. Compliance information for IR2304PBF should be verified with the current manufacturer documentation, as compliance status may differ between obsolete and active product variants.

Q: What applications are suitable for the IR2304 / IR2304PBF?

A: These gate drivers are designed for half-bridge topologies driving IGBT and N-Channel MOSFET power switches. Typical applications include DC-DC converters, motor control, and power inverter circuits operating within the 10V to 20V supply voltage range and 600V bootstrap voltage rating.

Q: Is the 8-DIP package still widely available?

A: The 8-DIP through-hole package remains in production. The IR2304PBF is available in bulk packaging, ensuring supply availability for both prototype and production quantities.
