Product details
Overview
HS3AB R5G from Taiwan Semiconductor is a 3A, 50V surface-mount Schottky rectifier in DO-214AA (SMB) package, featuring 1.0V max forward voltage at 3A/25°C, 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 R5G datasheet, HS3AB R5G pinout, HS3AB R5G application, or HS3AB R5G equivalent, key selection criteria include VRRM=50V, IF=3A, low-profile SMB package compatibility, thermal resistance of 60°C/W, and J-STD-020 Level 1 moisture sensitivity.
Technical Context
This device is a single-die, glass-passivated silicon junction rectifier with cathode band polarity marking. Its 50V repetitive peak reverse voltage and 100A non-repetitive surge current support high-efficiency operation in 60Hz–100kHz switching topologies.
Thermal performance is defined by RθJA=60°C/W and maximum junction temperature of +150°C. Reverse leakage remains ≤10μA at 25°C and ≤250μA at 100°C under rated VR, enabling stable operation in thermally constrained designs.
Key Specifications

| IF | 3 A continuous - Sustains full-load current in compact 12–24V output SMPS without forced cooling |
| VF @ 3A, 25°C | ≤1.0 V - Minimizes conduction loss (≤3W dissipation), critical for >85% efficiency targets |
| IFSM | 100 A (8.3ms) - Withstands inrush and transient surges common during cold-start in wall adapters |
| RθJA | 60 °C/W - Enables natural-convection thermal design on standard 1-oz FR4 PCBs with minimal copper area |
| Junction capacitance | 80 pF @ 1MHz, 4V - Limits high-frequency switching noise and EMI in <500kHz converters |
| Reverse recovery time | ≤50 ns - Reduces switching losses and improves efficiency in hard-switched flyback and forward converters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-3EJH05-M3/5B | VRRM=50V, IF=3A, VF=1.05V @ 3A, trr=50ns, same DO-214AA package | Identical voltage/current ratings but slightly higher VF; qualified to AEC-Q101 for automotive-grade use | Select for automotive infotainment or ADAS auxiliary supplies requiring extended qualification |
| ON Semiconductor MUR350G | VRRM=50V, IF=3A, VF=1.15V @ 3A, trr=75ns, DO-214AA package | Higher VF and slower recovery increase conduction and switching loss in high-frequency designs | Acceptable for cost-sensitive 50–100kHz applications where 0.15V VF penalty is tolerable |
Compared with VS-3EJH05-M3/5B and MUR350G, HS3AB R5G delivers the lowest forward voltage (≤1.0V) and tightest thermal resistance (60°C/W) in its class, making it optimal for space-constrained, high-efficiency 65–300kHz SMPS where thermal headroom and light-load efficiency are critical.

FAQ
What is the maximum junction temperature rating for HS3AB R5G?
The HS3AB R5G has a maximum junction temperature (TJMAX) of +150°C, verified per absolute maximum ratings table. This allows reliable operation in enclosed industrial environments up to 70°C ambient when mounted on standard FR4 with adequate copper pour. Derating begins above 25°C ambient per the forward current derating curve in the HS3AB R5G datasheet.
Is HS3AB R5G RoHS and halogen-free compliant?
Yes, HS3AB R5G is fully RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound and matte tin-plated leads meet environmental requirements for lead-free assembly and green manufacturing. Compliance documentation is available upon request for HS3AB R5G.
What is the reverse leakage current specification for HS3AB R5G at elevated temperature?
At 100°C junction temperature and rated reverse voltage, HS3AB R5G exhibits ≤250μA reverse leakage current (IR). At 25°C, the limit is ≤10μA. These values are measured per pulse test conditions (PW = 30ms) and support stable light-load regulation in standby power circuits.
Does HS3AB R5G have a defined moisture sensitivity level (MSL)?
Yes, HS3AB R5G is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life at ≤30°C/85% RH and requires no baking prior to reflow. This simplifies SMT line integration and eliminates moisture-related popcorning risk during lead-free reflow profiles.
What is the typical junction-to-ambient thermal resistance (RθJA) for HS3AB R5G?
The typical junction-to-ambient thermal resistance for HS3AB R5G is 60°C/W, measured on standard JEDEC 2S2P test board. This value assumes minimum recommended PCB copper area per the DO-214AA footprint and enables natural-convection thermal design in most 3A applications without additional heatsinking.
