Product details
Overview
MUR110SH from Taiwan Semiconductor is a 1A, 100V ultra-fast 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 snubber circuits.
For engineers reviewing the MUR110SH datasheet, MUR110SH pinout, MUR110SH application, or MUR110SH equivalent, key selection criteria include repetitive peak reverse voltage (100V), ultra-fast trr (25ns), low VF (0.875V), AEC-Q101 qualification, and DO-214AA (SMB) package compatibility with automated placement.
Technical Context
This single-die, unidirectional silicon rectifier operates with a maximum junction temperature of 175°C and exhibits low thermal resistance (RθJL = 17°C/W). Its ultra-fast recovery enables high-frequency switching in power conversion stages without excessive switching loss.
The device features a cathode-band polarity indicator, matte tin-plated leads compliant with J-STD-002, and moisture sensitivity level 1 per J-STD-020 - confirming suitability for standard reflow assembly without dry-pack requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06 | Same 1A/600V rating but 50ns trr; higher VF (1.15V @ 1A); TO-277 package | Less suitable for >150 kHz designs due to slower recovery; requires different footprint | Select when higher VRRM margin is needed and frequency ≤100 kHz |
| ON Semi MUR110E | Identical 1A/100V/25ns specs; same DO-214AA package; AEC-Q101 qualified | No functional or layout difference; direct second-source option | Preferred for dual-sourcing strategy in automotive production programs |
Compared with STTH1R06 and MUR110E, the MUR110SH offers identical ultra-fast timing and AEC-Q101 validation in DO-214AA, while MUR110E provides true second-source equivalence, whereas STTH1R06 trades speed for higher voltage rating and different packaging.

FAQ
What is the maximum repetitive peak reverse voltage for MUR110SH?
The MUR110SH has a maximum repetitive peak reverse voltage (VRRM) of 100 V. This rating defines the highest reverse-biased voltage the device can block repeatedly without breakdown. It is validated per JEDEC test conditions and must not be exceeded in circuit design, especially in automotive transients where load-dump spikes may occur.
Is MUR110SH qualified for automotive applications?
Yes, the MUR110SH is AEC-Q101 qualified. This certification confirms it has passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and unbiased highly accelerated stress testing (uHAST), making it suitable for under-hood and body-control module applications per automotive OEM requirements.
What is the forward voltage drop of MUR110SH at rated current?
The MUR110SH exhibits a typical forward voltage (VF) of 0.875 V at 1 A and 25°C junction temperature. At 150°C, VF drops to 0.710 V due to negative temperature coefficient - a key characteristic enabling stable conduction in thermally demanding automotive environments.
Does MUR110SH have a defined reverse recovery time?
Yes, the MUR110SH has a specified reverse recovery time (trr) of 25 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and IRR = 0.25 A. This ultra-fast value is measured per JEDEC standard and directly impacts switching loss and EMI in high-frequency power supplies.
What package type does MUR110SH use?
The MUR110SH uses the DO-214AA (SMB) surface-mount package. It features a molded epoxy case rated UL 94V-0, matte tin-plated leads compliant with J-STD-002, and a cathode band for polarity identification - all supporting automated pick-and-place and lead-free reflow assembly.
