Product details
Overview
MUR460S from Taiwan Semiconductor is a 4A, 600V ultra-fast recovery surface-mount rectifier in DO-214AB (SMC) package, featuring 50 ns reverse recovery time, 1.25 V max forward voltage at 4A/25°C, and 75 A peak surge current - deployed in high-frequency switching mode power supplies for telecom and computing infrastructure.
For engineers reviewing the MUR460S datasheet, MUR460S pinout, MUR460S application, or MUR460S equivalent, key selection criteria include repetitive peak reverse voltage (600 V), thermal resistance (RθJC = 8.5 °C/W), junction temperature range (–55 to +175 °C), and moisture sensitivity level (J-STD-020 Level 1).
Technical Context
The MUR460S employs a glass-passivated silicon junction optimized for high-efficiency, high-frequency rectification. Its ultra-fast recovery (trr ≤ 50 ns) minimizes switching losses in SMPS topologies operating above 50 kHz, while the single-die configuration ensures predictable thermal behavior under repetitive surge conditions (IFSM = 75 A, 8.3 ms half-sine).
Designed for automated SMT assembly, the device features matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. Polarity is marked by a cathode band, and the DO-214AB (SMC) package meets UL 94V-0 flammability rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports DC bus voltages up to 420 V RMS in bridge configurations without derating |
| IF | 4 A continuous - rated for sustained conduction in primary-side rectifiers of 100–200 W SMPS |
| trr | ≤ 50 ns - enables operation in >100 kHz converters with low reverse recovery loss |
| VF (max) | 1.25 V @ 4 A, 25°C - limits conduction loss to ≤5 W per device at full load |
| RθJC | 8.5 °C/W - allows ~8.8 W power dissipation before reaching TJ = 175°C with minimal heatsinking |
| IFSM | 75 A (8.3 ms) - withstands inrush currents in offline AC-DC front-ends |
| TJ range | –55 to +175 °C - qualified for industrial ambient and high-power-density PCB layouts |

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, trr = 35 ns, TO-277 package (smaller footprint than SMC) | Lower trr improves light-load efficiency but requires revised pad layout | Preferred where board space is constrained and <35 ns recovery is critical |
| ES4D-E3/57T | 600 V VRRM, 4 A IF, trr = 50 ns, same DO-214AB (SMC) package, higher IFSM (100 A) | Higher surge rating suits harsher inrush environments; identical mounting | Drop-in replacement when enhanced surge immunity is required without layout change |
Compared with STTH4L06S and ES4D-E3/57T, the MUR460S offers balanced trade-offs: identical 600 V/4 A rating and DO-214AB compatibility with ES4D-E3/57T, while delivering lower cost than STTH4L06S without sacrificing thermal robustness (RθJC = 8.5 °C/W vs. 12.5 °C/W typical for TO-277).

FAQ
What is the maximum junction temperature rating for the MUR460S?
The MUR460S has a maximum junction temperature (TJ) rating of +175 °C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet F2102. This allows the MUR460S to operate reliably in high-ambient environments such as enclosed server power supplies or industrial motor drives where heatsinking is limited. Derating curves confirm usable current capacity down to 0 A at 175 °C ambient.
Does the MUR460S have a specified reverse recovery time, and how is it measured?
Yes, the MUR460S specifies a reverse recovery time (trr) of ≤50 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, IRR = 0.25 A, per Figure 6 test circuit in the MUR420S–MUR460S datasheet. This value applies directly to the MUR460S variant and distinguishes it from the 25 ns rating of the MUR420S, reflecting voltage-dependent carrier lifetime optimization.
Is the MUR460S RoHS and halogen-free compliant?
Yes, the MUR460S is fully RoHS compliant per EU Directive 2011/65/EU and halogen-free per IEC 61249-2-21. These compliance statements appear in the "Features" section of the Taiwan Semiconductor datasheet F2102 and are confirmed by material declarations provided by TSC for the DO-214AB (SMC) package construction and lead finish.
What is the moisture sensitivity level (MSL) of the MUR460S, and what does it mean for assembly?
The MUR460S has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30 °C/60% RH without baking prior to reflow. This eliminates floor-life constraints and simplifies SMT line integration - a key advantage for high-volume automated placement in telecom and computing manufacturing.
Can the MUR460S be used as a direct replacement for the MUR440S in an existing design?
Yes, the MUR460S is a direct voltage-grade upgrade from the MUR440S, sharing identical package (DO-214AB), pinout, thermal characteristics (RθJC = 8.5 °C/W), and electrical parameters except VRRM (600 V vs. 400 V) and VF (1.25 V max vs. 1.25 V max). No PCB changes are required, and the MUR460S provides additional margin against voltage transients in the same footprint.
