Product details
Overview
S3MHM6G from Taiwan Semiconductor is a 3A, 600V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring 1.15V max forward voltage at 3A, 100A non-repetitive surge capability, and 150°C maximum junction temperature - deployed in AC/DC front-end stages of industrial SMPS and LED drivers.
For engineers reviewing the S3MHM6G datasheet, S3MHM6G pinout, S3MHM6G application, or S3MHM6G equivalent, key selection criteria include VRRM=600V, IFSM=100A, VF≤1.15V @3A, TJmax=150°C, and DO-214AB thermal performance (RθJL=13°C/W).
Technical Context
This single-die standard recovery rectifier operates with a reverse recovery time (trr) of 1500 ns under IF=0.5A/IR=1.0A/Irr=0.25A conditions and exhibits 60 pF junction capacitance at 1 MHz and 4.0V reverse bias. Its glass-passivated junction ensures stable operation across -55°C to +150°C ambient range.
The device complies with J-STD-020 moisture sensitivity level 1, UL 94V-0 molding compound, and JESD 201 Class 2 whisker resistance. Cathode polarity is marked by a visible band on the DO-214AB body.
Key Specifications

Applications
| Industrial SMPS Front-End | LED Driver Input Rectification |
|---|---|
Use Scenario: Single-phase AC input rectification in 100–300W open-frame industrial power supplies operating at 50/60 Hz. IC Role / Device Role / Timing Role: Standard recovery rectifier providing unidirectional conduction path; not a timing or control device. Use Value: 600V VRRM allows 400VAC nominal input with 50% safety margin; 100A IFSM withstands transformer inrush without derating. | Use Scenario: Bridge rectification in constant-current LED drivers for street lighting and high-bay fixtures. IC Role / Device Role / Timing Role: Discrete power rectifier handling 3A average forward current; no signal conditioning or regulation function. Use Value: Low VF (≤1.15V) reduces conduction loss in thermally constrained aluminum-core PCBs; DO-214AB footprint enables compact layout. |
| AC-DC Adapter Secondary | DC-DC Converter Input Stage |
Use Scenario: Output rectification in isolated flyback adapters rated up to 45W with universal AC input (90–264VAC). IC Role / Device Role / Timing Role: Power diode conducting during transformer demagnetization phase; no timing or feedback role. Use Value: 150°C TJmax rating permits operation in sealed enclosures; 60 pF CJ minimizes capacitive coupling noise into feedback circuits. | Use Scenario: Input rectification stage in 48V-to-12V isolated half-bridge DC-DC converters for telecom equipment. IC Role / Device Role / Timing Role: High-surge-capable rectifier feeding bulk storage capacitor; operates outside control loop timing path. Use Value: RθJL = 13°C/W enables direct thermal coupling to chassis ground plane; 1.15V VF limits power dissipation to <3.5W at full load. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar standard recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | VRRM=600V, IF=3A, VF=1.15V, trr=1500ns, same DO-214AB package | Identical electrical specs; STMicroelectronics variant with identical thermal and surge ratings | Drop-in alternative if dual-sourcing required; validated for same SMPS and adapter designs |
| ES3J | VRRM=600V, IF=3A, VF=1.15V, trr=1500ns, DO-214AB package, but IR=5µA @25°C (vs. 10µA for S3MHM6G) | Lower leakage supports higher ambient temperature operation in sealed LED drivers | Preferred where <5µA reverse leakage is mandated at 25°C; otherwise electrically interchangeable |
Compared with STTH3L06S and ES3J, the S3MHM6G offers identical VRRM, IF, VF, and trr in DO-214AB, differing only in reverse leakage (10µA vs. 5µA) and manufacturer-specific qualification - making it suitable for cost-sensitive industrial SMPS where 10µA IR is acceptable.

FAQ
What is the maximum junction temperature rating for the S3MHM6G?
The S3MHM6G has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet. This allows reliable operation in enclosed industrial power supplies where ambient temperatures exceed 85°C. The S3MHM6G's RθJL of 13°C/W further supports thermal management without external heatsinking under typical 3A DC loads.
Does the S3MHM6G have a RoHS and halogen-free designation?
Yes, the S3MHM6G is RoHS compliant and halogen-free, as explicitly stated in the "Features" section of the Taiwan Semiconductor S3A–S3M datasheet (Version O2301). These compliance attributes are certified per IPC-1752A and meet EU Directive 2011/65/EU requirements - essential for export-ready industrial and consumer power supply designs.
What is the reverse recovery time (trr) specification for the S3MHM6G?
The S3MHM6G has a reverse recovery time (trr) of 1500 ns, measured under IF = 0.5A, IR = 1.0A, and Irr = 0.25A conditions. This value is confirmed in the "ELECTRICAL SPECIFICATIONS" table of the official datasheet. The S3MHM6G is a standard recovery rectifier, not an ultrafast or soft-recovery type, so designers should account for this trr in EMI filtering and snubber design for 50–100 kHz switching topologies.
Is the S3MHM6G suitable for use in a full-wave bridge configuration?
Yes, the S3MHM6G is commonly used in discrete full-wave bridge rectifiers due to its 600V VRRM, 100A IFSM, and DO-214AB package compatibility with standard bridge layouts. Each S3MHM6G handles one leg of the bridge; four units form a complete bridge. Its cathode band marking ensures correct polarity orientation during automated placement - critical for functional validation in high-volume adapter manufacturing.
What packaging and reel quantity is offered for the S3MHM6G?
The S3MHM6G is supplied in DO-214AB (SMC) package on 3,000-piece tape-and-reel format, as specified in the "ORDERING INFORMATION" section of the Taiwan Semiconductor datasheet. This standard reel size aligns with SMT line feeders and supports JIT production scheduling. Aetrix Electronics maintains full traceability for each reel, including lot code, date code (YW), and factory code (F) per marking diagram shown in the datasheet.
