Product details
Overview
S1GLSH from Taiwan Semiconductor is a 1.2A, 400V standard surface-mount silicon rectifier diode in SOD-123HE package, designed for DC-DC converter output stages and automotive snubber circuits. It delivers 50A non-repetitive surge current capability, operates up to 175°C junction temperature, and exhibits ≤1.3V forward voltage at 1.2A and 25°C.
For engineers reviewing the S1GLSH datasheet, S1GLSH pinout, S1GLSH application, or S1GLSH equivalent, key selection criteria include its AEC-Q101 qualification, moisture sensitivity level 1 rating, 46°C/W junction-to-lead thermal resistance, and compatibility with automated SMT placement on PCBs with 5mm × 5mm copper pads.
Technical Context
The S1GLSH is a single-die, unidirectional standard recovery rectifier optimized for medium-voltage, moderate-current power conversion. Its 400V repetitive peak reverse voltage (VRRM) and 280V RMS reverse voltage rating support operation in 24V–48V automotive and industrial bus systems with transient margin.
Thermal performance is defined by RθJL = 46°C/W and RθJA = 86°C/W on a standardized 5mm × 5mm Cu pad test board. Electrical behavior includes ≤5µA reverse leakage at 25°C and ≤150µA at 125°C under rated VR, confirming stable blocking in high-temperature environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semi MUR120SFT1G | 200V VRRM, 1.2A IF, ultrafast recovery (trr = 75 ns), TO-277 package | Better suited for high-frequency switching where reverse recovery loss dominates | Select when operating above 100 kHz or requiring <100 ns trr; not drop-in due to different package and voltage rating |
| Vishay VS-1N4937-M3/54 | 600V VRRM, 1A IF, DO-41 through-hole, standard recovery | Lower current rating and through-hole mounting limit use in dense SMT automotive modules | Consider only for legacy through-hole designs or where 600V margin is mandatory and 0.2A derating is acceptable |
Compared with MUR120SFT1G and VS-1N4937-M3/54, the S1GLSH uniquely balances 400V rating, 1.2A current, SOD-123HE SMT compatibility, AEC-Q101 qualification, and MSL Level 1-making it optimal for new automotive SMT power supplies where reliability, manufacturability, and thermal efficiency are jointly prioritized.

FAQ
What is the peak repetitive reverse voltage rating of the S1GLSH?
The S1GLSH has a peak repetitive reverse voltage (VRRM) rating of 400 V. This value is specified in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version A2103) and defines the maximum reverse-bias voltage the device can block continuously without breakdown. It is critical for ensuring safe operation in 48V automotive systems with transient overvoltage margins.
Is the S1GLSH qualified for automotive applications?
Yes, the S1GLSH is AEC-Q101 qualified per the manufacturer's documentation. This qualification confirms successful completion of stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and high-temperature reverse bias (HTRB). The S1GLSH is explicitly recommended for automotive applications such as car lighting and DC-DC converters in the official product summary.
What is the thermal resistance from junction to lead for the S1GLSH?
The junction-to-lead thermal resistance (RθJL) of the S1GLSH is 46°C/W, measured on a standardized 5mm × 5mm copper pad test board. This parameter enables accurate thermal modeling when the device is soldered directly to PCB copper, supporting passive cooling design without additional heatsinking in many automotive and industrial implementations of the S1GLSH.
Does the S1GLSH have moisture sensitivity level (MSL) certification?
Yes, the S1GLSH is rated Moisture Sensitivity Level 1 per J-STD-020. This means it has no floor life limitation and may be stored indefinitely at ambient conditions without dry-pack requirements. It is fully compatible with standard reflow soldering profiles without pre-baking-a key advantage for high-throughput SMT lines handling the S1GLSH.
What packaging and reel quantity is offered for the S1GLSH?
The S1GLSH is supplied in SOD-123HE package on tape-and-reel format, with 10,000 units per reel. This packaging supports automated pick-and-place assembly and aligns with industry-standard SMT logistics. The marking code "1GLS" appears on the device body, consistent with Taiwan Semiconductor's ordering nomenclature for the S1GLSH variant.
