Product details
Overview
MUR320S M6G from Taiwan Semiconductor is a 3A, 200V ultra-fast recovery surface-mount rectifier in DO-214AB (SMC) package, featuring 25ns reverse recovery time, 0.875V forward voltage at 3A/25°C, and 75A peak surge current-designed for high-frequency freewheeling and switching-mode power supplies in telecom and computing infrastructure.
For engineers reviewing the MUR320S M6G datasheet, MUR320S M6G pinout, MUR320S M6G application, or MUR320S M6G equivalent, key selection criteria include VRRM = 200V, trr = 25ns, IF = 3A continuous, thermal resistance RθJL = 11°C/W, and RoHS/halogen-free compliance per IEC 61249-2-21.
Technical Context
This single-die ultra-fast rectifier uses glass-passivated junction technology to achieve low forward voltage and rapid carrier recombination, enabling efficient operation in 100–500 kHz SMPS topologies. Its 25ns recovery time minimizes switching losses during diode commutation in synchronous and quasi-resonant converters.
The DO-214AB (SMC) package provides robust thermal conduction via lead-frame mounting, with 0.210g mass and UL 94V-0 molding compound-optimized for automated placement and reflow soldering per J-STD-002, while meeting JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum repetitive reverse blocking voltage; defines safe operating range in flyback/clamp circuits |
| IF | 3 A - continuous forward current rating at TL = 75°C; determines heatsink sizing in DC-DC output stages |
| trr | 25 ns - ultra-fast reverse recovery time at IF = 0.5A, IR = 1.0A, Irr = 0.25A; reduces turn-off loss and EMI in high-frequency converters |
| VF | 0.875 V - forward voltage drop at IF = 3A, TJ = 25°C; directly impacts conduction loss and thermal rise |
| RθJL | 11 °C/W - junction-to-lead thermal resistance; enables direct PCB copper pour thermal coupling without heatsink in ≤2W dissipation |
| IFSM | 75 A - non-repetitive peak surge current (8.3ms half-sine); supports inrush and fault-current handling in AC-input rectification |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | VRRM = 600V, trr = 35ns, VF = 0.95V @ 3A | Higher voltage rating but slower recovery; suited for 400V+ PFC front-ends | Select when system requires >200V blocking margin and can tolerate higher trr-related loss |
| ES3D-E3/57T | VRRM = 200V, trr = 35ns, VF = 0.92V @ 3A, same DO-214AB package | Near-identical voltage/current specs but 40% longer trr; lower cost in high-volume consumer designs | Acceptable where 25ns vs. 35ns recovery has negligible impact on efficiency or EMI |
Compared with STTH3L06S and ES3D-E3/57T, the MUR320S M6G delivers the shortest reverse recovery time (25ns) within its 200V class, making it optimal for high-frequency, low-loss SMPS where switching speed directly governs thermal and efficiency targets.

FAQ
What is the maximum junction temperature rating for the MUR320S M6G?
The MUR320S M6G has a maximum junction temperature (TJ) of +175°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating enables reliable operation in thermally constrained environments such as sealed server power modules or enclosed industrial converters when combined with appropriate PCB copper area for heat spreading. The MUR320S M6G maintains specified electrical parameters up to this limit.
Does the MUR320S M6G meet RoHS and halogen-free requirements?
Yes, the MUR320S M6G is RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in the "Features" section of the Taiwan Semiconductor datasheet. The device uses green molding compound and matte tin-plated leads, satisfying environmental compliance mandates for commercial and industrial electronics sold in EU, China, and North America. The MUR320S M6G carries no restricted substances above threshold limits.
What is the reverse recovery time (trr) specification for the MUR320S M6G?
The MUR320S M6G has a typical reverse recovery time (trr) of 25 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A at TA = 25°C. This value is explicitly listed in the "ELECTRICAL SPECIFICATIONS" table for the MUR320S variant. The MUR320S M6G achieves this ultra-fast recovery through optimized silicon doping and passivation, distinguishing it from slower 35–50 ns alternatives.
Is the MUR320S M6G suitable for automated SMT assembly?
Yes, the MUR320S M6G is designed for automated placement and reflow soldering, as stated in its "FEATURES" list. It meets moisture sensitivity level 1 per J-STD-020, eliminating pre-bake requirements, and features matte tin-plated leads compliant with J-STD-002. The DO-214AB (SMC) package geometry and 0.210g weight ensure stable pick-and-place performance. The MUR320S M6G is routinely deployed in high-volume SMT lines for telecom and computing hardware.
What is the forward voltage (VF) of the MUR320S M6G at rated current?
The MUR320S M6G exhibits a maximum forward voltage (VF) of 0.875 V at IF = 3 A and TJ = 25°C, per the "ELECTRICAL SPECIFICATIONS" table. At elevated junction temperature (150°C), VF drops to 0.710 V due to negative temperature coefficient of silicon diodes. This low VF directly reduces conduction loss-critical for maintaining efficiency in compact, high-density power supplies using the MUR320S M6G.
