Product details
Overview
MUR160A from Taiwan Semiconductor is a 1 A, 600 V high-efficiency ultrafast recovery rectifier diode in DO-204AL (DO-41) package, featuring 50 ns reverse recovery time, 1.25 V max forward voltage at 1 A/25°C, and 175°C maximum junction temperature - deployed in DC-DC converters and switching-mode inverters.
For engineers reviewing the MUR160A datasheet, MUR160A pinout, MUR160A application, or MUR160A equivalent, key selection criteria include repetitive peak reverse voltage (600 V), surge current capability (35 A), thermal resistance (50 °C/W), and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
The MUR160A is a single-die, silicon planar epitaxial ultrafast rectifier optimized for high-frequency switching applications. Its 50 ns trr and low 1.25 V VF enable reduced switching losses and improved efficiency in SMPS topologies.
Designed with pure tin-plated leads compliant with J-STD-002 and JESD201 Class 2 whisker testing, the device supports lead-free reflow soldering while maintaining stable operation from –55°C to +175°C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands repetitive reverse voltage up to 600 V without breakdown, enabling use in 400 V DC bus systems with safety margin. |
| IF | 1 A continuous - Rated average forward current under specified thermal conditions; derates linearly above 75°C ambient. |
| IFSM | 35 A (8.3 ms half-sine) - Supports high transient surge currents during power-up or fault events in converter circuits. |
| trr | 50 ns - Ultrafast recovery minimizes reverse recovery charge (Qrr), reducing switching losses and EMI in high-frequency designs. |
| TJ max | +175°C - Enables operation in high-temperature environments such as under-hood automotive electronics or enclosed industrial power supplies. |
| RθJA | 50 °C/W - Thermal resistance from junction to ambient in standard PCB mount; informs heatsinking requirements for sustained 1 A operation. |
| VF @ 1A/25°C | 1.25 V max - Low forward drop improves conduction efficiency and reduces thermal load compared to standard fast recovery diodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06 | Same 1 A / 600 V rating; trr = 50 ns; VF = 1.3 V max at 1 A/25°C; TO-220AC package. | Higher thermal mass but requires mounting hardware; not axial-leaded; unsuitable for through-hole wave-soldered boards. | Select when board-level heatsinking is available and axial form factor is not required. |
| ES1J | 1 A / 600 V; trr = 35 ns; VF = 1.7 V max; DO-204AL package; no AEC-Q101 option. | Lower trr improves high-frequency efficiency but higher VF increases conduction loss; no automotive qualification path. | Choose for cost-sensitive non-automotive SMPS where fastest recovery is prioritized over forward loss. |
Compared with STTH1R06 and ES1J, the MUR160A offers optimal balance of axial DO-41 compatibility, 1.25 V low VF, 50 ns trr, and AEC-Q101 availability - making it preferred for space-constrained, automotive-qualified, or legacy through-hole power designs.

FAQ
What is the maximum junction temperature rating for the MUR160A?
The MUR160A has a maximum junction temperature (TJ) rating of +175°C, verified per absolute maximum ratings table. This allows operation in high-temperature environments such as engine compartments or sealed power enclosures. The MUR160A maintains stable electrical characteristics across its full –55°C to +175°C junction range, and thermal design must ensure RθJA (50 °C/W) is respected under actual board layout conditions.
Is the MUR160A RoHS and halogen-free compliant?
Yes, the MUR160A is RoHS compliant and halogen-free, as explicitly stated in the official Taiwan Semiconductor datasheet. The molding compound meets UL 94V-0 flammability rating, and terminals use pure tin plating compliant with J-STD-002 solderability standards. These attributes are confirmed for the MUR160A and all variants including MUR160AHA0G.
Does the MUR160A have AEC-Q101 qualification?
The base MUR160A is not AEC-Q101 qualified, but the MUR160AH and MUR160AHA0G variants are explicitly marked as AEC-Q101 qualified in the ordering information table. "H" suffix denotes qualification per AEC-Q101 stress test requirements for discrete semiconductors used in automotive electronics.
What is the reverse recovery time (trr) of the MUR160A and under what test conditions?
The MUR160A has a reverse recovery time (trr) of 50 ns maximum, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the electrical specifications table. This ultrafast trr enables efficient operation in high-frequency switching circuits such as 100–500 kHz DC-DC converters where minimizing Qrr-related losses is critical.
What packaging options are available for the MUR160A?
The MUR160A is offered in DO-204AL (DO-41) package with two packing formats: 5,000 units per tape-and-reel (MUR160A and MUR160AH) and 3,000 units per ammo box (MUR160A A0G and MUR160AHA0G). All variants share identical mechanical dimensions, marking code "MUR160A", and cathode band polarity indication.
