Taiwan Semiconductor Corporation MURF1620CT

Overview

MURF1620CT from Taiwan Semiconductor is a dual-die ultra-fast recovery rectifier in ITO-220AB package, rated for 16 A average forward current, 200 V repetitive peak reverse voltage, and 25 ns reverse recovery time at 25°C. It serves as a freewheeling or output rectifier in high-frequency switching power supplies.

For engineers reviewing the MURF1620CT datasheet, MURF1620CT pinout, MURF1620CT application, or MURF1620CT equivalent, key selection criteria include its 25 ns trr, 0.975 V max VF at 8 A/25°C, 3 °C/W RθJC, AEC-Q101 qualification option (MURF1620CTH), and ITO-220AB thermal-mechanical compatibility with heatsink-mounting designs.

Technical Context

The MURF1620CT integrates two independent ultra-fast silicon junction diodes in a single ITO-220AB case, enabling dual-channel operation without shared thermal or electrical coupling beyond common case connection. Its glass-passivated chip junction ensures stable performance across -55°C to +150°C junction temperature range.

Designed for hard-switched topologies, it delivers 25 ns reverse recovery time under IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A test conditions-critical for minimizing switching losses in DC-DC converters operating above 100 kHz. The 3 °C/W junction-to-case thermal resistance supports direct heatsink mounting without thermal interface material in moderate-power applications.

FAQ

What is the maximum junction temperature rating for the MURF1620CT?

The MURF1620CT has a maximum junction temperature (TJ MAX) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating applies across the full operating range and enables reliable operation in enclosed industrial enclosures or under forced-air cooling. Derating curves confirm usable current capacity down to 125°C case temperature, ensuring design margin for thermal transients. The MURF1620CT maintains specified VF and trr performance within this limit.

Is the MURF1620CT pin-compatible with the MURF1640CT or MURF1660CT?

Yes, the MURF1620CT is mechanically and electrically pin-compatible with MURF1640CT and MURF1660CT - all share identical ITO-220AB package dimensions, terminal layout, marking orientation, and dual-cathode pinout. However, VRRM differs (200 V vs. 400 V/600 V), so substitution requires verification of reverse voltage margin in the target circuit. The MURF1620CT remains functionally interchangeable only where 200 V blocking suffices.

Does the MURF1620CT have AEC-Q101 qualification?

The base MURF1620CT is not AEC-Q101 qualified; however, the MURF1620CTH variant - indicated by the "H" suffix in the ordering code - is fully AEC-Q101 qualified and tested per stress requirements for automotive discrete semiconductors. Both versions share identical electrical and thermal specifications, with qualification limited to the H-suffix part. Designers targeting automotive applications must specify MURF1620CTH to ensure compliance.

What is the reverse recovery time (trr) test condition for the MURF1620CT?

The MURF1620CT reverse recovery time of 25 ns is measured under the standardized condition: IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A, with pulse width per note 1 in the datasheet. This reflects real-world hard-switching behavior in DC-DC converters. At elevated junction temperatures (125°C), trr increases slightly but remains below 35 ns. The MURF1620CT's trr is confirmed via oscilloscope-based double-pulse testing per JEDEC standards.

How does the thermal resistance of the MURF1620CT compare to similar dual rectifiers?

The MURF1620CT specifies a junction-to-case thermal resistance (RθJC) of 3 °C/W - lower than STTH1602CT (3.5 °C/W) and comparable to IXYS MUR1620CT (3.0 °C/W). This value is measured with the tab fully mounted to a copper heatsink per JESD51-14. The 3 °C/W rating directly enables higher sustained current in thermally constrained designs, and the MURF1620CT achieves this without thermal interface material in many implementations.
