Product details
Overview
MUR460S from Taiwan Semiconductor is a 4A, 600V ultra-fast recovery surface-mount rectifier diode 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 uses a glass-passivated silicon junction optimized for high-efficiency switching applications, with ultra-fast trr ≤ 50 ns under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions. Its single-die configuration and DO-214AB package support automated SMT placement and meet JESD201 Class 2 whisker resistance.
Thermal performance is defined by RθJA = 45 °C/W (free-air) and RθJC = 8.5 °C/W, enabling reliable operation up to TJ = 175 °C. Reverse leakage remains ≤ 10 μA at 25 °C and ≤ 250 μA at 150 °C under rated VR, supporting stable freewheeling in high-duty-cycle converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| trr | ≤ 50 ns - minimizes switching losses and EMI in >100 kHz topologies |
| VF (max) | 1.25 V @ 4 A, 25 °C - limits conduction loss to <5.0 W at full load |
| IFSM | 75 A (8.3 ms half-sine) - withstands inrush and transient surges in offline converters |
| TJ max | +175 °C - enables operation in thermally constrained enclosures without forced cooling |

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 | Same 600 V VRRM, 4 A IF, but trr = 35 ns (faster); VF = 1.7 V (higher) | Better suited for >300 kHz ZVS/ZCS topologies where recovery speed dominates conduction loss | Select when minimizing reverse recovery charge is critical and higher VF is acceptable |
| ES4D-E3/57T | Same DO-214AB package, 600 V, 4 A, but trr = 75 ns (slower); VF = 1.15 V (lower) | Preferred in cost-sensitive, lower-frequency (<100 kHz) flyback or forward converters | Select when conduction efficiency and BOM cost outweigh fast recovery needs |
Compared with STTH4L06S and ES4D-E3/57T, the MUR460S delivers balanced trade-off between recovery speed (50 ns), forward drop (1.25 V), and thermal resistance (8.5 °C/W), making it optimal for mainstream 100–200 kHz telecom and server SMPS designs where both loss components matter.

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 (Version F2102). This allows sustained operation in thermally demanding environments such as enclosed server PSUs or industrial motor drives. Derating curves confirm usable current capacity down to 0 A at 175 °C ambient when mounted on standard FR-4 PCB with 1-inch² copper pour.
Does the MUR460S have a specified reverse recovery time, and under what test conditions?
Yes, the MUR460S specifies a reverse recovery time (trr) of ≤ 50 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the official Taiwan Semiconductor datasheet (Page 2, Electrical Specifications). This value applies to both MUR440S and MUR460S variants and is critical for minimizing switching losses in high-frequency converters.
Is the MUR460S RoHS and halogen-free compliant?
Yes, the MUR460S is RoHS compliant per EU Directive 2011/65/EU and halogen-free per IEC 61249-2-21, as explicitly stated in the "Features" section of the Taiwan Semiconductor datasheet (Version F2102). The device uses matte tin-plated leads and UL 94V-0 molding compound, satisfying environmental and safety requirements for modern electronics manufacturing.
What is the thermal resistance from junction to case (RθJC) for the MUR460S?
The MUR460S has a junction-to-case thermal resistance (RθJC) of 8.5 °C/W, published in the Thermal Performance section of the Taiwan Semiconductor datasheet (Version F2102). This value enables effective heat transfer from the die to the cathode tab, supporting thermal design when the device is mounted on copper-filled pads or external heatsinks in high-power density layouts.
What packaging and moisture sensitivity level does the MUR460S use?
The MUR460S is supplied in DO-214AB (SMC) package on 3,000-piece tape-and-reel, with moisture sensitivity level (MSL) rated at Level 1 per J-STD-020 - meaning it is not moisture-sensitive and may be stored indefinitely at ambient conditions without baking prior to reflow. This simplifies SMT line handling and eliminates floor-life constraints.
