Product Overview
IR2104STRPBF is the tape-and-reel SOIC-8 ordering code for Infineon’s IR2104S 600 V half-bridge gate-driver family. It provides a level-shifted floating high-side channel and a low-side channel for driving N-channel MOSFET or IGBT half bridges from a 10 V to 20 V gate-drive supply.
The driver includes undervoltage lockout, cross-conduction prevention, internally set deadtime and a shutdown input. These functions reduce external logic requirements, but the device is still part of a bootstrap-based power stage: bootstrap capacitor sizing, diode choice, switching-node transients and power-device gate charge determine whether the final gate-drive waveform is acceptable.

Infineon currently lists IR2104STRPBF as the active/recommended tape-and-reel SOIC-8 OPN within the IR2104S product family.
Functional Highlights
600 V level shifting enables high-side N-channel drive
The floating channel can operate with the switching node moving over a high common-mode range, allowing a bootstrap-supplied high-side gate in half-bridge topologies.
Internal interlock features simplify control logic
Cross-conduction prevention, deadtime and shutdown reduce the amount of external glue logic required around the driver, while still requiring system-level validation of timing and fault behavior.
Applications / Application Fit
- Half-bridge MOSFET or IGBT power stages
- Motor-control and power-conversion gate drive
- Inverter and photovoltaic switching stages where a bootstrap high-side architecture is appropriate
Design Considerations
Size the bootstrap capacitor for the actual MOSFET/IGBT gate charge, leakage and maximum high-side on-time.
Keep the gate-drive and switching loops short; high dV/dt at the switch node can couple into logic and gate paths.
Confirm propagation delay and internal deadtime against the switching frequency and required shoot-through margin.
No customer PDF download is published for this test because the official family PDF did not explicitly contain the full exact OPN IR2104STRPBF under the current strict PDF identity rule.
