Taiwan Semiconductor Corporation MURF8L60H

Overview

MURF8L60H from Taiwan Semiconductor is an AEC-Q101-qualified, single-die ultrafast recovery rectifier in ITO-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 MURF8L60H datasheet, MURF8L60H pinout, MURF8L60H application, or MURF8L60H equivalent, key selection criteria include its AEC-Q101 qualification, low VF conduction loss, high-temperature junction stability up to +175°C, and ITO-220AC thermal performance (R_θJC = 2.8°C/W).

Technical Context

The MURF8L60H is a planar epitaxial silicon ultrafast recovery rectifier optimized for high-efficiency power conversion. Its 65ns trr and 1.3V VF at full rated current enable reduced switching losses in hard-switched topologies, while the single-die construction ensures consistent thermal behavior under transient surge conditions.

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

FAQ

What does the "H" suffix in MURF8L60H signify?

The "H" suffix in MURF8L60H explicitly denotes AEC-Q101 qualification per the manufacturer's ordering code specification. This certification confirms that the MURF8L60H has passed rigorous stress testing-including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing-required for automotive power electronics. The base part MURF8L60 lacks this qualification.

Is the tab of the MURF8L60H electrically isolated?

Yes, the tab of the MURF8L60H is electrically isolated from both the anode and cathode terminals, as defined by the ITO-220AC package standard. This isolation allows direct mechanical mounting to a heatsink without additional insulation hardware, simplifying thermal design in space-constrained automotive and industrial applications where the MURF8L60H is commonly used.

What is the maximum allowable mounting torque for the MURF8L60H?

The maximum mounting torque for the MURF8L60H is 0.56 N·m, as specified in the mechanical data section of the official datasheet. Exceeding this value risks damaging the internal die attach or lead frame integrity. Proper torque control ensures reliable thermal contact between the ITO-220AC tab and heatsink while preserving long-term mechanical reliability of the MURF8L60H in vibration-prone environments.

How does the MURF8L60H perform at elevated junction temperatures?

The MURF8L60H maintains rated performance up to +175°C junction temperature, with reverse leakage increasing to 200 µA at 125°C (vs. 5 µA at 25°C). Its planar epitaxial structure ensures stable V_F and t_rr characteristics across the full –55°C to +175°C range, enabling robust operation in under-hood automotive locations where the MURF8L60H is routinely deployed.

Can the MURF8L60H replace standard FRD or SR diodes in existing designs?

The MURF8L60H can replace standard fast recovery diodes (FRDs) with matching V_RRM and I_F ratings, provided thermal and layout constraints accommodate the ITO-220AC footprint and isolated tab. However, it is not a direct replacement for synchronous rectifiers (SRs), which require gate drive control - the MURF8L60H remains a passive, uncontrolled ultrafast rectifier requiring no external bias.
