Product details
Overview
MUR120SH from Taiwan Semiconductor is a 1A, 200V 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 snubber circuits.
For engineers reviewing the MUR120SH datasheet, MUR120SH pinout, MUR120SH application, or MUR120SH equivalent, key selection criteria include VRRM = 200V, IF = 1A, trr = 25ns, VF = 0.875V (25°C), and DO-214AA (SMB) package compatibility with automated placement.
Technical Context
This single-die discrete rectifier operates across -55°C to +175°C junction temperature range and delivers ultra-fast switching performance critical for high-frequency power conversion. Its 17°C/W junction-to-lead thermal resistance supports reliable thermal dissipation in compact layouts.
The device features AEC-Q101 qualification, moisture sensitivity level 1 per J-STD-020, and matte tin-plated leads compliant with J-STD-002 solderability-enabling robust use in automotive-grade power systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R02UF | VRRM = 200V, trr = 30ns, VF = 0.95V @ 1A - slightly higher VF and slower recovery | Not AEC-Q101 qualified; limited to industrial/commercial use | Select when automotive qualification is not required and cost is primary constraint |
| ES1D-E3/54 | VRRM = 200V, trr = 35ns, VF = 0.92V @ 1A - higher VF, slower recovery, same SMB package | JEDEC-qualified but not AEC-Q101; lacks automotive traceability documentation | Acceptable for non-safety-critical consumer power supplies where qualification overhead is unnecessary |

FAQ
What is the maximum junction temperature rating for MUR120SH?
The MUR120SH has a maximum junction temperature (TJMAX) of +175°C, enabling operation in under-hood automotive environments and high-power-density industrial power supplies. This rating is validated per JEDEC JESD22-A108 and supported by its 17°C/W junction-to-lead thermal resistance. The MUR120SH maintains specified electrical parameters across the full -55°C to +175°C range.
Is MUR120SH suitable for automotive applications?
Yes, the MUR120SH is AEC-Q101 qualified and manufactured to automotive-grade process controls, including JESD201 Class 2 whisker testing and J-STD-020 Level 1 moisture sensitivity. It is explicitly listed in the datasheet for automotive applications including car lighting and DC-DC converters. The MUR120SH meets all stress-test requirements for automotive power electronics.
What is the reverse recovery time (trr) of MUR120SH and how is it measured?
The MUR120SH 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 confirmed across the MUR105SH–MUR120SH subgroup and directly contributes to reduced switching loss in high-frequency converters. The MUR120SH achieves this via optimized epitaxial layer doping and lifetime control.
Does MUR120SH have halogen-free and RoHS-compliant construction?
Yes, the MUR120SH uses halogen-free molding compound per IEC 61249-2-21 and is fully RoHS compliant. Its matte tin-plated leads meet J-STD-002 solderability standards, and the entire construction-including die attach, passivation, and encapsulation-is verified for restricted substance compliance. This ensures environmental safety and regulatory acceptance in global electronics manufacturing. The MUR120SH carries full material declarations.
What packaging format is available for MUR120SH?
The MUR120SH is supplied in DO-214AA (SMB) package on 3,000-piece tape-and-reel format, optimized for high-speed pick-and-place assembly. The package features polarity indicated by cathode band, UL 94V-0 rated molding compound, and JESD201 Class 2 whisker-resistant terminations. No alternate packaging options (e.g., bulk or ammo pack) are specified for the MUR120SH in official documentation.
