Product details
Overview
MUR460-E3/73 from Vishay General Semiconductor is an ultrafast plastic rectifier diode in DO-201AD package, rated for 600 V repetitive peak reverse voltage, 4.0 A average forward current, and 50 ns typical reverse recovery time. It serves as a high-efficiency freewheeling or output rectifier in switching-mode power supplies for telecom and computing equipment.
For engineers reviewing the MUR460-E3/73 datasheet, MUR460-E3/73 pinout, MUR460-E3/73 application, or MUR460-E3/73 equivalent, key selection criteria include reverse recovery time, forward voltage at operating temperature, surge current capability, thermal resistance, and RoHS-compliant matte tin plating.
Technical Context
This device is a single-die, glass-passivated silicon junction diode optimized for high-frequency switching applications. Its ultrafast trr (50 ns typ.) and low VF (1.05 V at 3.0 A, TJ = 150 °C) minimize conduction and switching losses in DC-DC converters and inverters.
The DO-201AD package provides robust thermal performance with RθJA = 28 °C/W (PCB-mounted), enabling reliable operation up to TJ = 175 °C. The cathode is marked by a color band, and leads are matte tin-plated per J-STD-002.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH4L06D | 600 V VRRM, 4 A IF(AV), 60 ns trr (typ.), TO-220AC package | Higher thermal mass but larger footprint; requires heatsink for >2 A continuous | Prefer when board space allows and higher surge margin is needed |

FAQ
What is the maximum junction temperature rating for the MUR460-E3/73?
The MUR460-E3/73 has a maximum junction temperature (TJ max.) of +175 °C, allowing operation in thermally demanding environments such as enclosed server power supplies or industrial converters. This rating is validated per Vishay's thermal characterization and supports derated current handling up to ambient temperatures of +85 °C on standard PCB layouts.
Is the MUR460-E3/73 RoHS-compliant and halogen-free?
Yes, the MUR460-E3/73 is RoHS-compliant (per EU Directive 2011/65/EU) and carries the E3 suffix indicating commercial-grade, lead-free, matte tin-plated leads. It is not halogen-free; for halogen-free compliance, the MUR460-M3/73 variant must be selected instead.
What does the "/73" suffix mean in MUR460-E3/73?
The "/73" suffix denotes the packaging configuration: ammo pack packaging containing 1000 units. This differs from "/54", which indicates 13-inch diameter paper tape and reel with 1400 units. Both share identical electrical and thermal specifications.
How does the MUR460-E3/73 compare to the MUR440 in terms of voltage rating?
The MUR460-E3/73 is rated for 600 V VRRM, whereas the MUR440 is rated for 400 V VRRM. All other key parameters-including IF(AV) = 4.0 A, trr = 50 ns (typ.), VF = 1.05 V @ 3 A/150 °C, and DO-201AD package-are identical. Voltage selection depends on circuit peak reverse stress requirements.
Can the MUR460-E3/73 replace a standard FR407 rectifier in an existing design?
The MUR460-E3/73 can replace FR407 in many cases due to matching DO-201AD package and 4 A/600 V ratings, but its 50 ns trr is significantly faster than FR407's 500 ns-reducing switching losses. Verify layout thermal margins and snubber requirements, as faster recovery may increase voltage overshoot if parasitic inductance is unmitigated.
