Product details
Overview
MUR310S V7G from Taiwan Semiconductor is a 3A, 100V 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 - deployed in high-frequency switching mode power supplies for telecom and computing infrastructure.
For engineers reviewing the MUR310S V7G datasheet, MUR310S V7G pinout, MUR310S V7G application, or MUR310S V7G equivalent, key selection criteria include ultra-fast trr performance, thermal resistance of 11°C/W, RoHS/halogen-free compliance, and J-STD-020 Level 1 moisture sensitivity for automated SMT assembly.
Technical Context
This discrete ultra-fast rectifier uses a glass-passivated silicon junction to achieve tight control of reverse recovery characteristics. Its 25ns trr and low VF enable high-efficiency operation in 100–500kHz SMPS topologies where diode switching loss dominates conduction loss.
The DO-214AB (SMC) package provides robust thermal dissipation with 11°C/W junction-to-lead resistance and supports reflow soldering per J-STD-002. Polarity is marked by a cathode band; device weight is 0.210g.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse voltage before breakdown; defines safe operating range in flyback/clamp circuits |
| IF | 3 A - continuous forward current rating at 75°C case temperature; sets average power handling capability |
| trr | 25 ns - ultra-fast reverse recovery time at IF = 0.5A, IR = 1.0A, Irr = 0.25A; minimizes switching loss in high-frequency converters |
| VF | 0.875 V @ 3A, 25°C - forward voltage drop; directly impacts conduction loss and thermal design margin |
| RθJL | 11 °C/W - junction-to-lead thermal resistance; enables accurate thermal modeling for PCB copper pour sizing |
| IFSM | 75 A - non-repetitive peak surge current (8.3ms half-sine); determines robustness against line transients and startup surges |
Pinout & Package
DO-214AB (SMC) surface-mount package with molded plastic body (UL 94V-0), matte tin-plated leads, and cathode polarity indicated by a band on the body.
| Pin/Terminal | Circuit Role | Design Meaning |

Applications
| Server Power Supply Rectification | Telecom DC-DC Converter Output |
|---|---|
Use Scenario: Secondary-side rectification in 48V input, 12V/54A isolated forward converter for rack-mounted servers. IC Role / Device Role / Timing Role: Ultra-fast freewheeling diode conducting during synchronous MOSFET off-time; critical for minimizing voltage overshoot and ringback. Use Value: 25ns trr limits reverse recovery charge (Qrr), reducing cross-conduction loss and enabling tighter duty-cycle control vs. standard fast recovery diodes. | Use Scenario: Output rectification in 36–75V input telecom brick supplying 3.3V/20A to baseband processing boards. IC Role / Device Role / Timing Role: Primary unidirectional current path delivering regulated output; operates continuously at 3A with minimal conduction loss. Use Value: 0.875V VF at 3A/25°C lowers average power dissipation to ~2.6W, easing thermal management on dense telecom PCBs. |
| Industrial Motor Drive Snubber | Automotive ADAS Power Module |
Use Scenario: Freewheeling path across IGBTs in 24V BLDC motor drive inverters for HVAC and pump control. IC Role / Device Role / Timing Role: Clamps inductive kickback during IGBT turn-off; must recover before next switching cycle to prevent shoot-through. Use Value: 100V VRRM and 75A IFSM withstand repetitive 40V–60V transients and startup surges without degradation. | Use Scenario: Input rectification in 12V battery-fed power module for radar sensor ECU with -40°C to +125°C ambient requirement. IC Role / Device Role / Timing Role: AC/DC front-end rectifier converting alternator output to stable DC bus; exposed to load dump pulses. Use Value: -55°C to +175°C TJ rating and JESD201 Class 2 whisker resistance ensure reliability under automotive thermal and mechanical stress. |
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 | 600V VRRM, 3A IF, 35ns trr, TO-277 package | Higher voltage rating but slower recovery; suited for universal-input PFC, not optimal for 100V-class SMPS | Select when system requires >400V reverse blocking; avoid if trr <30ns is mandatory |
| MBR3100T3G | 100V VRRM, 3A IF, Schottky architecture, 0.72V VF, no reverse recovery | No Qrr or trr; limited to ≤125°C junction due to leakage rise; unsuitable for high-temp industrial use | Prefer for low-VF, low-noise 85°C ambient apps; reject for 150°C+ environments or high VRMS stress |
Compared with STTH3L06S and MBR3100T3G, the MUR310S V7G delivers optimal balance of 100V rating, 25ns trr, and 175°C TJ capability - making it uniquely suitable for compact, high-frequency, thermally constrained rectification where both speed and ruggedness are required.
