Product details
Overview
MUR1660CT from Taiwan Semiconductor is a 16A, 600V ultra-fast recovery dual common-cathode rectifier diode in TO-220AB package, featuring 50 ns reverse recovery time, 1.500 V forward voltage at 8A/25°C, and 175°C maximum junction temperature-used in high-frequency switching mode power supplies and freewheeling paths.
For engineers reviewing the MUR1660CT datasheet, MUR1660CT pinout, MUR1660CT application, or MUR1660CT equivalent, key selection criteria include peak reverse voltage (600 V), thermal resistance (2 °C/W), surge current rating (100 A), and AEC-Q101 qualification availability for automotive-grade reliability validation.
Technical Context
The MUR1660CT integrates two ultra-fast silicon epitaxial planar diodes in a single TO-220AB package with common cathode configuration, enabling synchronous rectification or dual-path DC output. Its 50 ns trr and low Qrr support operation in 100–500 kHz SMPS topologies without excessive switching loss.
Thermal performance is defined by 2 °C/W junction-to-case resistance and 175°C max TJ, allowing sustained 16A conduction under forced-air or heatsink-cooled conditions. The glass-passivated junction ensures stable leakage (<10 µA @ 25°C) and robustness against humidity and thermal cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports DC bus voltages up to 420 V RMS in bridge configurations |
| IF(AV) | 16 A - continuous average forward current per diode at TC = 100°C |
| IFSM | 100 A - non-repetitive surge capability for startup/load-dump transients |
| trr | 50 ns - enables efficient operation in high-frequency converters (>200 kHz) |
| RθJC | 2 °C/W - allows thermal design with standard TO-220 heatsinks for 16A steady-state |
| VF @ 8A/25°C | 1.500 V - defines conduction loss of ~12 W per diode at full load |
| IR @ 600V/25°C | 10 µA - minimal leakage ensures low standby power in offline PSUs |
Pinout & Package
Package: TO-220AB, 3-terminal, common-cathode dual diode configuration. Case is electrically connected to cathode (pin 2). Mounting tab requires isolation if not used as heat sink return.

FAQ
What is the maximum junction temperature rating for MUR1660CT?
The MUR1660CT has a maximum junction temperature (TJ MAX) of +175°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating enables reliable operation in high-ambient environments such as enclosed industrial power supplies or under-hood automotive modules. Derating curves confirm 16A average current is sustainable at case temperatures up to 100°C when mounted on a heatsink with adequate thermal interface.
Does MUR1660CT have AEC-Q101 qualification?
Yes, the MUR1660CTH variant is AEC-Q101 qualified, as specified in the ordering information section of the Taiwan Semiconductor datasheet. The standard MUR1660CT is not automatically qualified; only units marked with the "H" suffix meet AEC-Q101 stress test requirements for automotive applications. Engineers must specify MUR1660CTH for automotive designs requiring formal qualification evidence.
What is the reverse recovery time (trr) of MUR1660CT and how is it measured?
The MUR1660CT has a typical reverse recovery time (trr) of 50 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the manufacturer's test conditions. This value is confirmed across both MUR1640CT and MUR1660CT variants in the same datasheet revision (I2104). The measurement uses a standardized half-sine waveform with controlled di/dt and voltage slew rate to ensure repeatability.
Is MUR1660CT a dual-diode device and what is its internal configuration?
Yes, MUR1660CT contains two independent ultra-fast rectifier dies in a single TO-220AB package with a common-cathode configuration-pins 1 and 3 are anodes, and pin 2 is the shared cathode (and electrically connected to the metal tab). This structure supports dual-output supplies, interleaved rectification, or redundant paths without external wiring.
What is the forward voltage drop of MUR1660CT at rated current and temperature?
The MUR1660CT exhibits a maximum forward voltage (VF) of 1.500 V at IF = 8 A and TJ = 25°C, and 1.200 V at the same current but TJ = 150°C. These values are specified in the Electrical Specifications table of the official datasheet and reflect the trade-off between higher voltage rating and conduction loss-critical for thermal modeling in high-power SMPS designs.
