Product details
Overview
MUR310SH from Taiwan Semiconductor is a 3A, 100V ultra-fast recovery surface-mount rectifier diode in DO-214AB (SMC) package, featuring 25ns reverse recovery time, 0.875V forward voltage at 3A/25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or snubber diode in high-frequency DC-DC converters.
For engineers reviewing the MUR310SH datasheet, MUR310SH pinout, MUR310SH application, or MUR310SH equivalent, key selection criteria include its 100V VRRM, 75A IFSM, 11°C/W RθJL, -55°C to +175°C operating range, and DO-214AB mechanical compatibility with automated SMT assembly.
Technical Context
The MUR310SH employs a glass-passivated silicon junction optimized for ultra-fast switching, enabling efficient operation in high-frequency power conversion topologies. Its 25ns trr and low Qrr minimize switching losses during turn-off, while the 0.875V VF at rated current supports thermal management in compact layouts.
Designed for automotive and industrial environments, the device meets AEC-Q101 stress testing requirements and JESD201 Class 2 whisker resistance. Its moisture sensitivity level 1 rating and halogen-free construction comply with J-STD-020 and IEC 61249-2-21 standards.

FAQ
What is the maximum junction temperature rating for MUR310SH?
The MUR310SH has a maximum junction temperature (TJ) rating of +175°C, enabling reliable operation in high-ambient environments such as automotive engine compartments. This rating is validated across its full operating range from –55°C to +175°C and supports thermal design margins in sealed enclosures without forced airflow. The MUR310SH maintains specified electrical performance up to this limit when derated per the forward current curve in the datasheet.
Is MUR310SH compatible with lead-free reflow soldering processes?
Yes, the MUR310SH is fully compatible with lead-free reflow soldering per J-STD-002, using matte tin-plated leads and a moisture sensitivity level 1 rating. Its DO-214AB package withstands peak temperatures up to 260°C for 10 seconds without degradation. No pre-bake is required, simplifying manufacturing flow. The MUR310SH's construction ensures robust intermetallic formation and solder joint integrity in standard Pb-free profiles.
Does MUR310SH have automotive qualification?
Yes, the MUR310SH is AEC-Q101 qualified, having passed all stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and highly accelerated stress test (HAST). This qualification confirms its suitability for automotive powertrain, body electronics, and ADAS applications. The MUR310SH's qualification status is documented in Taiwan Semiconductor's official AEC-Q101 certificate for the MUR3xSH family.
What is the reverse recovery time (trr) of MUR310SH and how is it measured?
The MUR310SH 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 value reflects the time required for minority carriers to clear the junction after forward conduction, directly impacting switching loss and EMI. The MUR310SH's 25 ns trr is confirmed across temperature and is critical for high-frequency (>500 kHz) converter designs.
What packaging and reel quantity is available for MUR310SH?
The MUR310SH is supplied in DO-214AB (SMC) package on 3,000-piece tape-and-reel format, compatible with standard SMT pick-and-place equipment. The reel complies with EIA-481-D standards and includes moisture barrier bagging with desiccant and humidity indicator card. Each reel is traceable to wafer lot and test batch, supporting full supply chain transparency for automotive and industrial customers using the MUR310SH.
