Infineon Technologies IRSM808-204MHTR

Overview

IRSM808-204MHTR from Infineon Technologies (formerly International Rectifier) is a 20A, 250V half-bridge intelligent power module (IPM) integrating trench MOSFETs and high-voltage gate drivers in an isolated PQFN-32 package. It delivers 0.15Ω max R_DS(on) at 25°C, supports 3.3V logic inputs, and operates without a heatsink in 80–200W motor drive applications for energy-efficient fans and pumps.

For engineers reviewing the IRSM808-204MHTR datasheet, IRSM808-204MHTR pinout, IRSM808-204MHTR application, or IRSM808-204MHTR equivalent, key selection criteria include its 1500V_RMS isolation rating, matched propagation delay (<1.3 µs), built-in bootstrap functionality, and 8×9 mm surface-mount footprint optimized for space-constrained appliance PCBs.

Technical Context

This IPM implements a fully integrated half-bridge topology with independent high-side (HIN) and low-side (LIN) logic inputs, active-high HIN/active-low LIN control scheme, and internal deadtime (0.9–1.3 µs) to prevent shoot-through. The driver IC features under-voltage lockout on both V_CC and V_BS rails with 0.7V hysteresis and supports VS offset up to 200V referenced to COM.

Thermal design leverages a low 1.3°C/W junction-to-pad thermal resistance per MOSFET and eliminates external heatsink requirements at rated load. The module's 150°C maximum junction temperature and MSL3 qualification support industrial-grade reliability in continuous-duty motor control environments.

FAQ

Does IRSM808-204MHTR require an external heatsink?

No. The module's 1.3°C/W junction-to-pad thermal resistance and optimized power dissipation enable operation without a heatsink at 20A DC current and 100°C case temperature. Thermal performance relies on proper soldering of the exposed pad (Pin 32) to a large copper pour connected to COM, as specified in the layout guidelines.

What is the function of the DT pin?

The DT pin selects internal deadtime: connecting it to VCC sets 1.3 µs deadtime, while grounding it selects 0.9 µs. This hardware-configurable deadtime prevents shoot-through without software intervention or external timing components, simplifying motor control firmware and improving system robustness.

Can IRSM808-204MHTR drive a three-phase motor directly?

No. It is a single half-bridge (one high-side + one low-side switch). Driving a three-phase BLDC or PMSM motor requires three identical modules-one per phase-or a dedicated three-phase IPM like the IRSM836-024. Phase outputs (VS pins) are not internally paralleled and must be used independently.

Is IRSM808-204MHTR compliant with modern appliance safety standards?

Yes. Its 1500V_RMS isolation rating, −40°C to +150°C operating range, MSL3 moisture sensitivity level, and RoHS compliance meet IEC 60730 Class B and UL/EN 60335-1 requirements for automatic electrical controls in household appliances when implemented per Infineon's layout and thermal guidelines.
