Product details
Overview
MUR460 A0G from Taiwan Semiconductor is a 4A, 600V ultra-fast recovery rectifier diode in DO-201AD package, featuring 50 ns reverse recovery time, 1.28 V forward voltage at 4A/25°C, and 125 A surge current capability; used in high-frequency switching mode power supplies and freewheeling paths.
For engineers reviewing the MUR460 A0G datasheet, MUR460 A0G pinout, MUR460 A0G application, or MUR460 A0G equivalent, key selection criteria include peak reverse voltage rating, thermal resistance (RθJL = 15 °C/W), junction temperature range (–55 to +175 °C), and AEC-Q101 qualification status.
Technical Context
This single-die, glass-passivated silicon rectifier operates with ultra-fast switching characteristics optimized for DC-DC converters and SMPS output stages. Its 600 V VRRM, 50 ns trr, and low 1.28 V VF at rated current support high-efficiency energy transfer under high-frequency operation.
The DO-201AD package provides robust thermal performance (RθJA = 28 °C/W) and mechanical reliability, with pure tin-plated leads compliant to J-STD-002 solderability and JESD201 Class 2 whisker resistance.
Key Specifications

| VRRM | 600 V - maximum repetitive reverse blocking voltage without breakdown |
| IF | 4 A - continuous average forward current at TA = 75 °C |
| trr | 50 ns - fast recovery minimizes switching losses in >100 kHz topologies |
| VF | 1.28 V @ 4 A, 25 °C - low conduction loss improves system efficiency |
| IFSM | 125 A - withstands short-duration surge currents during startup or fault |
| TJ max | +175 °C - enables operation in high-temperature industrial environments |
| RθJL | 15 °C/W - efficient heat transfer to PCB copper or heatsink via lead frame |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH4L06S | 600 V VRRM, 4 A IF, 60 ns trr, TO-220AC package | Higher thermal mass but requires heatsink mounting; not DO-201AD drop-in | Preferred where board space allows larger footprint and higher surge margin is needed |
| ON Semi MUR460E | Identical 600 V/4 A rating, 50 ns trr, same DO-201AD package, but RoHS-compliant only (not halogen-free) | No AEC-Q101 option; different material compliance profile | Valid alternative if halogen-free requirement is waived and AEC-Q101 is not mandated |
Compared with STTH4L06S and MUR460E, the MUR460 A0G uniquely combines AEC-Q101 qualification, halogen-free construction, and DO-201AD form factor-making it optimal for space-constrained automotive and industrial designs requiring full regulatory alignment.

FAQ
What is the peak repetitive reverse voltage rating of the MUR460 A0G?
The MUR460 A0G has a peak repetitive reverse voltage (VRRM) rating of 600 V. This specification defines the maximum reverse-biased voltage the device can block repeatedly without avalanche breakdown. It is validated per JEDEC test conditions and applies across the full operating junction temperature range (–55 to +175 °C). The MUR460 A0G must not be operated beyond this limit in any design using the MUR460 A0G.
Is the MUR460 A0G qualified to AEC-Q101 standards?
No-the MUR460 A0G is not AEC-Q101 qualified. Only variants marked with "H" suffix (e.g., MUR460H or MUR460HA0G) meet AEC-Q101 requirements. The "A0G" suffix indicates DO-201AD packaging in ammo box format (500 units), but does not imply automotive qualification. Designers requiring AEC-Q101 must select the H-suffix version of the MUR460 A0G.
What is the forward voltage drop of the MUR460 A0G at rated current?
The MUR460 A0G exhibits a maximum forward voltage (VF) of 1.28 V at 4 A forward current and 25 °C junction temperature. This value is measured under pulsed conditions (PW = 0.3 ms) and represents worst-case conduction loss. At elevated temperatures (e.g., 125 °C), VF decreases slightly, improving efficiency in thermally stressed operation of the MUR460 A0G.
Does the MUR460 A0G have halogen-free construction?
Yes-the MUR460 A0G uses halogen-free molding compound compliant with IEC 61249-2-21. This is explicitly stated in the official Taiwan Semiconductor datasheet (Version J2105) and verified in the "Features" section. The halogen-free status applies to both the encapsulant and internal die attach materials, supporting environmentally regulated deployments where the MUR460 A0G is used.
What is the thermal resistance from junction to lead (RθJL) for the MUR460 A0G?
The junction-to-lead thermal resistance (RθJL) of the MUR460 A0G is 15 °C/W, as specified in the Thermal Performance table of the Taiwan Semiconductor datasheet. This parameter reflects heat flow from the silicon die to the lead frame under steady-state conditions and is critical for estimating temperature rise when the MUR460 A0G is soldered to copper pads or heatsinks.
