Product details
Overview
HS3AB M4G from Taiwan Semiconductor is a 3A, 50V surface-mount high-efficiency rectifier diode in DO-214AA (SMB) package, featuring 1.0V max forward voltage at 3A, 100A surge rating, and 50ns reverse recovery time. It serves as primary output rectifier in compact AC/DC adapters and SMPS.
For engineers reviewing the HS3AB M4G datasheet, HS3AB M4G pinout, HS3AB M4G application, or HS3AB M4G equivalent, key selection criteria include VRRM = 50V, IF = 3A continuous, low-profile SMB package compatibility, and thermal resistance RθJA = 60°C/W for board-level thermal design.
Technical Context
This single-die, glass-passivated silicon rectifier operates with junction temperature range –55°C to +150°C and meets JESD201 Class 2 whisker resistance. Its fast recovery (50ns) and low VF support high-frequency switching topologies up to several hundred kHz.
The device uses matte tin-plated leads compliant with J-STD-002 solderability and moisture sensitivity level 1 per J-STD-020 - enabling standard reflow without baking. Polarity is marked by cathode band on the SMB body.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse voltage; defines safe blocking capability in low-voltage secondary-side rectification |
| IF | 3 A - Continuous forward current rating; supports sustained 3A DC output in compact adapters |
| VF @ 3A | ≤1.0 V - Low conduction loss at rated current; reduces power dissipation and improves efficiency |
| trr | ≤50 ns - Fast reverse recovery; minimizes switching loss and EMI in high-frequency SMPS |
| RθJA | 60 °C/W - Junction-to-ambient thermal resistance; enables thermal design on standard FR-4 with minimal copper area |
| IFSM | 100 A - Non-repetitive surge rating; withstands inrush and transient overloads in AC input stages |
| Junction temp | –55°C to +150°C - Wide operating range suitable for enclosed, thermally constrained environments |
Pinout & Package
Package: DO-214AA (SMB), low-profile surface-mount case with cathode band marking. Weight: 0.093 g. UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry | Connected to transformer secondary or switch node; requires thermal pad connection for IF = 3A operation |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; ties to output capacitor negative or common rail; critical for polarity-sensitive PCB layout |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | VF ≤ 1.0 V @ 3A ensures <0.3W conduction loss, reducing heatsink need in space-constrained adapters |
| Fast switching performance | trr ≤ 50 ns enables use in 200–500 kHz flyback and LLC converters without excessive switching loss |
| Glass passivated junction | Enhances long-term reliability under humidity and thermal cycling vs. epoxy-passivated alternatives |
| Moisture sensitivity level 1 | Eliminates pre-bake requirement for SMT assembly, lowering manufacturing cost and cycle time |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | VRRM = 60V, VF = 0.95V @ 3A, trr = 35ns, same SMB package | Slightly higher VRRM margin; faster recovery but lower surge rating (IFSM = 75A) | Preferred where tighter VF tolerance or sub-40ns trr is required; verify surge robustness in high-inrush designs |
| ON Semi MUR305 | VRRM = 50V, VF = 1.15V @ 3A, trr = 75ns, DO-201AD axial lead | Higher VF, slower recovery, through-hole package - not drop-in compatible | Only suitable for legacy through-hole redesigns; requires PCB rework and thermal analysis for same power dissipation |
Compared with STTH3L06S and MUR305, the HS3AB M4G offers optimal balance of low VF, fast trr, and SMB surface-mount compatibility for new compact SMPS designs - while maintaining industry-standard surge and thermal ratings.

FAQ
What is the maximum junction temperature rating for HS3AB M4G?
The HS3AB M4G has a maximum junction temperature (TJMAX) of +150°C, verified per absolute maximum ratings table. This allows reliable operation in thermally constrained environments such as sealed adapters or densely packed monitor power boards. Derating curves confirm usable current down to 125°C ambient when mounted on standard 1-oz copper.
Is HS3AB M4G RoHS and halogen-free compliant?
Yes, HS3AB M4G is fully RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and all terminals meet EU Directive 2011/65/EU requirements. Certificate of Compliance is available upon request.
What does the 'M4G' suffix indicate in HS3AB M4G?
The 'M4G' suffix denotes Taiwan Semiconductor's internal packaging and environmental code: 'M' indicates DO-214AA (SMB) tape-and-reel packaging, '4' specifies 3,000 units per reel, and 'G' confirms green (halogen-free) compound. This matches ordering code HS3AB in the official datasheet version L2102.
Can HS3AB M4G replace HS3BB M4G in a 100V design?
No - HS3AB M4G is rated for VRRM = 50V only and must not be substituted for HS3BB M4G (100V) in circuits with peak reverse voltage exceeding 50V. Exceeding VRRM risks catastrophic failure. Always match the 'x' digit in HS3xB to required blocking voltage.
What is the reverse leakage current specification for HS3AB M4G at 100°C?
At TJ = 100°C and rated VR, HS3AB M4G exhibits maximum reverse current (IR) of 250 μA, per electrical specifications table. This value is measured under pulse conditions (PW = 30ms) and remains well within typical SMPS design margins for standby power loss.
