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 RoHS/halogen-free compliance for industrial-grade power conversion designs.
Technical Context
The MUR460S is a single-die, planar passivated silicon rectifier optimized for high-efficiency DC-DC conversion where fast switching and low conduction loss are critical. Its ultra-fast trr of 50 ns enables operation in 100 kHz–1 MHz SMPS topologies without excessive switching loss or EMI generation.
Designed with glass-passivated junction and matte tin-plated leads compliant with J-STD-002, the device supports automated SMT assembly and meets JESD201 Class 2 whisker resistance. Polarity is marked by cathode band; moisture sensitivity level is J-STD-020 Level 1.
Key Specifications

| IF | 4 A continuous - rated for sustained output current in mid-power adapters and auxiliary rails |
| trr | 50 ns - enables efficient operation in high-frequency flyback and forward converters |
| VF (max) | 1.25 V @ 4 A, 25°C - limits conduction loss to ≤5 W at full load in TO-220-equivalent thermal envelope |
| RθJC | 8.5 °C/W - allows direct heatsinking via PCB copper pour or clip for thermal management |
| IFSM | 75 A (8.3 ms half-sine) - withstands inrush and transient overloads in AC-DC front-ends |
| Junction temp | –55 to +175 °C - qualified for under-hood automotive auxiliary supplies and industrial control enclosures |

Applications
| Telecom AC-DC Adapters | Server PSU Secondary Rectification |
|---|---|
Use Scenario: 48 V input rectification in distributed power architecture (DPA) modules with 300 kHz synchronous rectification. IC Role / Device Role / Timing Role: Ultra-fast freewheeling diode in active-clamp forward topology, clamping leakage energy and enabling ZVS. Use Value: 50 ns trr minimizes reverse recovery charge (Qrr) to <15 nC, reducing cross-conduction loss in high-side FETs. | Use Scenario: Output rectification in 12 V/20 A VRM stages powering CPU/GPU rails in datacenter servers. IC Role / Device Role / Timing Role: Secondary-side uncontrolled rectifier replacing Schottky diodes where higher VRRM and lower cost are prioritized over VF. Use Value: 600 V rating provides margin against voltage spikes during load dump; 1.25 V VF yields ~5 W dissipation at full load, manageable with 2 oz copper. |
| Industrial Motor Drive Auxiliary Supply | Automotive Infotainment Power Module |
Use Scenario: 24 V AC-to-DC conversion for gate driver and logic supply in 3-phase inverter drives. IC Role / Device Role / Timing Role: Input bridge rectifier feeding offline controller IC with wide input range (18–32 VAC). Use Value: –55 to +175 °C operating range ensures functionality across ambient temperatures in enclosed motor cabinets. | Use Scenario: 12 V battery-fed DC-DC pre-regulator supplying 5 V/3.3 V rails for head unit MCU and display interface. IC Role / Device Role / Timing Role: Freewheeling diode across buck converter inductor during light-load discontinuous conduction mode (DCM). Use Value: Low Qrr and 50 ns trr prevent shoot-through in high-side switch during DCM transitions, improving efficiency at standby. |
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, 4 A, trr = 45 ns, VF = 1.3 V @ 4 A, DO-214AB | Slightly faster recovery but higher forward drop; higher leakage at 150°C (500 μA vs. 250 μA) | Preferred where minimal Qrr dominates over conduction loss |
| ON Semiconductor MUR460E | 600 V, 4 A, trr = 50 ns, VF = 1.25 V @ 4 A, same DO-214AB, AEC-Q101 qualified | Automotive-qualified variant with extended reliability testing and tighter parametric screening | Required for automotive infotainment or ADAS auxiliary supplies needing AEC-Q101 compliance |
Compared with STTH4L06S and MUR460E, the MUR460S offers identical electrical performance and footprint but targets industrial/commercial applications with cost-sensitive, high-volume SMT production - no AEC-Q101 qualification, yet fully compatible in non-automotive thermal and layout constraints.

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 operation in high-ambient environments such as enclosed power supplies or industrial control cabinets. Derating curves confirm 4 A continuous current is maintainable up to 125 °C case temperature when mounted on adequate copper area. The MUR460S must not exceed this limit to ensure long-term reliability.
Does the MUR460S have a specified reverse recovery time, and how is it measured?
Yes, the MUR460S has a specified reverse recovery time (trr) of 50 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, per the Electrical Specifications section of the Taiwan Semiconductor datasheet. This value applies to all variants in the MUR4xS family rated ≥400 V. The test circuit and waveform definitions are shown in Figure 6 of the datasheet. The MUR460S uses a planar epitaxial structure optimized for consistent trr across temperature and current.
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. The molding compound is UL 94V-0 rated, and terminals are matte tin-plated per J-STD-002. These compliance statements apply directly to the MUR460S - not inferred from family-level claims. No exemptions are claimed; full substance declarations are available upon request for the MUR460S.
What is the marking code printed on the MUR460S device body?
The MUR460S is marked with "MUR460S" on its body, as confirmed in the ORDERING INFORMATION and MARKING DIAGRAM sections of the Taiwan Semiconductor datasheet (Version F2102). The marking includes the full part number, green compound indicator ("G"), date code ("YW"), and factory code ("F"). No abbreviated or alternate markings (e.g., "460S") are used for this specific variant - the complete MUR460S identifier is laser-etched or molded for traceability and counterfeit prevention.
Can the MUR460S replace the MUR440S or MUR420S in an existing design?
Yes, the MUR460S is a direct drop-in replacement for MUR440S and MUR420S in the same DO-214AB (SMC) package, sharing identical pinout, thermal characteristics, and mechanical dimensions. Its higher VRRM (600 V vs. 400 V/200 V) adds margin without affecting layout or soldering. However, forward voltage is slightly higher (1.25 V vs. 1.05 V for MUR440S at 150°C), so thermal validation is recommended if operating near 175 °C. The MUR460S maintains the same 50 ns trr as MUR440S, ensuring unchanged switching behavior.
