Product details
Overview
MUR315S V7G from Taiwan Semiconductor is an ultra-fast recovery surface-mount rectifier diode with 150 V repetitive peak reverse voltage (VRRM), 3 A average forward current (IF), and 25 ns reverse recovery time (trr), designed for high-frequency switching mode power supplies in telecom and computing infrastructure.
For engineers reviewing the MUR315S V7G datasheet, MUR315S V7G pinout, MUR315S V7G application, or MUR315S V7G equivalent, key selection criteria include its DO-214AB (SMC) package compatibility, low forward voltage drop of 0.875 V at 3 A/25°C, and junction temperature range of –55°C to +175°C.
Technical Context
This device operates as a single-die, unidirectional silicon rectifier optimized for freewheeling and output rectification in DC-DC converters and AC-DC front-ends. Its ultra-fast recovery (25 ns) minimizes switching losses during high-frequency operation up to several hundred kHz.
The glass-passivated junction ensures stable performance under thermal cycling and humidity exposure, while the matte tin-plated leads meet J-STD-002 solderability requirements and JESD201 Class 2 whisker resistance standards.

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 | Same DO-214AB package; 600 V VRRM, 3 A IF, 35 ns trr, higher VF (0.95 V) | Better suited for higher-voltage PFC stages; less optimal for 150 V-class outputs due to higher conduction loss | Select when system requires >400 V blocking but same footprint and current rating |
| MBR3150T3G | TO-277 package (not SMC); Schottky architecture; 150 V VR, 3 A IF, no reverse recovery, but higher leakage (≤500 μA @ 125°C) | Zero trr eliminates switching loss, but leakage limits use in high-temp/harsh environments | Prefer where zero-recovery benefit outweighs thermal derating constraints and board space permits TO-277 |
Compared with STTH3L06S and MBR3150T3G, the MUR315S V7G delivers optimal balance of 150 V blocking, 25 ns recovery, and 0.875 V forward drop in the industry-standard DO-214AB footprint-making it ideal for cost-sensitive, thermally constrained 100–300 kHz SMPS designs.

FAQ
What is the maximum junction temperature rating for the MUR315S V7G?
The MUR315S V7G has a maximum junction temperature (TJ) rating of +175°C, enabling reliable operation in thermally demanding environments such as enclosed server PSUs or industrial motor drives. This rating is supported by its glass-passivated junction and DO-214AB package thermal resistance of 11°C/W (junction-to-lead). The MUR315S V7G must be mounted on appropriate copper area to maintain this limit under full 3 A load.
Does the MUR315S V7G have a specified reverse recovery time, and how is it measured?
Yes, the MUR315S V7G 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 per the datasheet. This ultra-fast value is critical for minimizing switching losses in high-frequency converters. The MUR315S V7G achieves this via optimized carrier lifetime control in its epitaxial silicon structure.
Is the MUR315S V7G RoHS and halogen-free compliant?
Yes, the MUR315S V7G is fully RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound meets UL 94V-0 flammability rating, and its matte tin-plated leads satisfy J-STD-002 solderability requirements. These certifications are confirmed in the official Taiwan Semiconductor documentation for the MUR3xxS family, including the MUR315S V7G variant.
What is the marking code and polarity identification for the MUR315S V7G?
The MUR315S V7G is marked with "MUR315S" on the device body, followed by date and factory codes (e.g., "GYWF"). Polarity is indicated by a distinct cathode band near one end of the DO-214AB package. This band corresponds to the cathode terminal, which must be connected toward the positive output rail in rectifier configurations. The MUR315S V7G follows standard diode polarity conventions for surface-mount assembly.
What is the forward voltage drop of the MUR315S V7G at elevated temperature?
The MUR315S V7G exhibits a forward voltage (VF) of 0.710 V at 3 A and 150°C junction temperature-lower than its 0.875 V value at 25°C due to negative temperature coefficient of silicon diodes. This behavior improves thermal stability in high-temperature operation. The MUR315S V7G maintains rated current capability across its full –55°C to +175°C junction range without derating until case temperature exceeds 75°C.
