Taiwan Semiconductor Corporation MUR8L60H

Overview

MUR8L60H from Taiwan Semiconductor is an AEC-Q101-qualified, single-die ultrafast recovery rectifier in TO-220AC package, rated for 8A average forward current and 600V repetitive peak reverse voltage, with 1.3V max forward voltage at 8A/25°C and 65ns typical reverse recovery time - deployed in automotive-grade DC-DC converters and switching inverters.

For engineers reviewing the MUR8L60H datasheet, MUR8L60H pinout, MUR8L60H application, or MUR8L60H equivalent, key selection criteria include its AEC-Q101 qualification, 100A non-repetitive surge rating, 2.5°C/W junction-to-case thermal resistance, and low VF performance under high-temperature operation up to 175°C junction.

Technical Context

The MUR8L60H is a single-die, planar epitaxial ultrafast rectifier optimized for high-efficiency switching power supplies. Its 65ns trr and 1.3V VF at full rated current enable reduced conduction and switching losses in hard-switched topologies.

Designed for automotive under-hood environments, it supports continuous operation from –55°C to +175°C junction temperature, meets JESD201 Class 2 whisker resistance, and uses matte tin-plated leads compliant with J-STD-002 solderability standards.

FAQ

What does the "H" suffix signify in MUR8L60H?

The "H" suffix in MUR8L60H explicitly denotes AEC-Q101 qualification - verified through accelerated stress testing including high-temperature reverse bias, temperature cycling, and unbiased highly accelerated stress testing. This distinguishes MUR8L60H from the standard MUR8L60 and confirms its suitability for automotive powertrain and chassis applications. The MUR8L60H retains identical electrical and thermal specifications as the base part but adds full automotive reliability validation.

Is MUR8L60H pin-compatible with standard TO-220AC rectifiers like MUR860?

Yes, MUR8L60H uses the industry-standard TO-220AC outline with identical mechanical dimensions, lead spacing, and terminal assignment (anode–cathode–tab). It shares the same 3-pin configuration and mounting footprint as MUR860, STTH8R06, and other TO-220AC ultrafast rectifiers. No PCB redesign is needed when upgrading to MUR8L60H, provided thermal and electrical derating align with the application's surge and temperature requirements.

What is the maximum recommended case temperature for MUR8L60H in continuous operation?

The MUR8L60H is rated for continuous operation up to +175°C junction temperature, and its TO-220AC package supports case temperatures up to +150°C when mounted on a properly sized heatsink with ≤0.56 N·m mounting torque. Derating curves in the datasheet show 8A average current is sustainable at 100°C case temperature; above that, linear derating applies down to zero current at 150°C case.

Does MUR8L60H require a thermal pad between the tab and heatsink?

No, MUR8L60H does not require a thermal pad - its metal tab is electrically connected to the cathode and designed for direct metal-to-metal contact with the heatsink. However, electrical isolation must be maintained if the heatsink is grounded or at a different potential. When isolation is needed, use a UL 94V-0 compliant insulating washer and thermal grease; do not use silicone-based pastes incompatible with matte tin plating.

How does MUR8L60H's 65ns reverse recovery time impact EMI in high-frequency SMPS?

MUR8L60H's 65ns trr significantly reduces reverse recovery di/dt and associated high-frequency ringing compared to standard fast recovery diodes (e.g., 150–250ns), lowering conducted EMI in 100–500 kHz switch-mode power supplies. This allows smaller input filters and relaxed layout constraints near the rectifier node, directly supporting CISPR-25 Class 5 compliance in automotive power modules without additional snubbers.
