Product details
Overview
MUR115SH from Taiwan Semiconductor is a 1A, 150V ultra-fast recovery surface-mount rectifier diode with glass-passivated junction, 25ns reverse recovery time, and 0.875V forward voltage at 1A/25°C, used in automotive DC-DC converters and freewheeling circuits.
For engineers reviewing the MUR115SH datasheet, MUR115SH pinout, MUR115SH application, or MUR115SH equivalent, key selection criteria include its AEC-Q101 qualification, DO-214AA (SMB) package, TJ = –55°C to +175°C operating range, and low IR of 2µA at 25°C.
Technical Context
This single-die, unidirectional silicon rectifier features an ultra-fast recovery mechanism optimized for high-frequency switching applications. Its 25ns trr and low Qrr minimize switching losses in snubber and freewheeling paths where rapid turn-off is critical.
The device operates across –55°C to +175°C junction temperature with 17°C/W junction-to-lead thermal resistance. It maintains 0.710V VF at 1A/150°C and exhibits only 50µA IR at rated VR and 150°C - enabling stable performance in under-hood automotive environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06S | Same 1A/600V rating but 50ns trr; VF = 0.95V @ 1A/25°C; TO-277 package | Higher VR and slower recovery limit use in 150V-class circuits requiring <30ns trr | Select when higher reverse voltage margin is needed and 50ns recovery is acceptable |

FAQ
What is the peak repetitive reverse voltage rating for MUR115SH?
The MUR115SH has a peak repetitive reverse voltage (VRRM) rating of 150 V. This value is specified in the Absolute Maximum Ratings table and defines the maximum reverse voltage the device can block repeatedly without breakdown. It is validated across the full operating temperature range and forms the basis for selecting appropriate voltage derating margins in automotive 12V/24V system designs.
Is MUR115SH qualified for automotive applications?
Yes, the MUR115SH is AEC-Q101 qualified. This qualification confirms that the device has passed rigorous stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD), making it suitable for use in automotive power electronics such as body control modules, lighting drivers, and DC-DC converters installed in engine compartments or passenger cabins.
What is the forward voltage drop of MUR115SH at 1A and 25°C?
The forward voltage drop (VF) of the MUR115SH is 0.875 V at IF = 1 A and TJ = 25°C, as specified in the Electrical Specifications table. This low VF contributes directly to reduced conduction losses and improved thermal performance compared to standard fast recovery diodes, especially in high-duty-cycle applications like automotive LED drivers.
What package type does MUR115SH use, and is it compatible with automated assembly?
The MUR115SH uses the DO-214AA (SMB) surface-mount package. It is fully compatible with automated pick-and-place equipment and standard reflow soldering profiles. The device meets J-STD-020 moisture sensitivity level 1 and features matte tin-plated leads that are solderable per J-STD-002, ensuring robust manufacturability in high-volume automotive electronics production.
What is the reverse recovery time (trr) of MUR115SH, and how is it measured?
The reverse recovery time (trr) of the MUR115SH is 25 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A at TA = 25°C. This ultra-fast trr is critical for minimizing switching losses and voltage overshoot in high-frequency power converters, particularly in automotive DC-DC stages operating above 100 kHz where diode recovery behavior significantly impacts efficiency and EMI.
