Product details
Overview
HS3B R7G from Taiwan Semiconductor is a 100 V, 3 A surface-mount high-efficiency rectifier diode in DO-214AB (SMC) package, featuring 150 A surge rating, 1.0 V max forward voltage at 3 A, and 10 µA max reverse leakage at 25°C. It serves as a freewheeling or output rectifier in switching-mode power supplies for telecom and computing systems.
For engineers reviewing the HS3B R7G datasheet, HS3B R7G pinout, HS3B R7G application, or HS3B R7G equivalent, key selection criteria include repetitive peak reverse voltage (100 V), thermal resistance (60 °C/W), junction capacitance (80 pF), reverse recovery time (50 ns), and moisture sensitivity level (J-STD-020 Level 1).
Technical Context
The HS3B R7G is a single-die, glass-passivated silicon rectifier optimized for high-frequency operation in DC-DC converters and offline SMPS. Its low-profile DO-214AB package supports automated placement and meets UL 94V-0 flammability requirements.
With a maximum junction temperature of 150°C and thermal resistance of 60°C/W, it delivers stable performance under continuous 3 A forward conduction. Reverse recovery time of ≤50 ns and junction capacitance of 80 pF at 1 MHz/4 V enable efficient switching in 100–500 kHz power stages.

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-3EYH01-M3/54 | Same DO-214AB package, 100 V VRRM, but VF = 1.15 V (max) at 3 A; trr = 75 ns | Slightly higher conduction and switching loss; less suitable for >250 kHz designs | Acceptable where thermal margin exists and cost sensitivity outweighs efficiency gain |
| ON Semiconductor MUR3100CT | TO-220AB package, dual common-cathode die, 100 V VRRM per diode, VF = 1.2 V (max), trr = 60 ns | Requires larger board area and heat sinking; not SMT-compatible | Preferred only when dual-diode configuration or higher surge tolerance (200 A) is mandatory |
Compared with VS-3EYH01-M3/54 and MUR3100CT, the HS3B R7G offers the lowest VF (1.0 V) and fastest trr (50 ns) in DO-214AB, enabling higher efficiency and smaller passive filtering in space-constrained telecom and server power supplies.

FAQ
What is the maximum junction temperature rating for HS3B R7G?
The HS3B R7G has a maximum junction temperature (TJ) rating of +150°C, allowing operation in high-ambient environments such as enclosed server power supplies or industrial control cabinets. This rating is validated under continuous 3 A forward current with proper PCB thermal relief. Derating curves in the datasheet confirm usable current capacity down to 1.5 A at 125°C ambient, making HS3B R7G suitable for thermally demanding deployments where thermal headroom is limited.
Does HS3B R7G meet RoHS and halogen-free requirements?
Yes, HS3B R7G is RoHS compliant and halogen-free per IEC 61249-2-21. The device uses matte tin-plated leads and UL 94V-0 compliant molding compound, with no brominated flame retardants or chlorine-based additives. These attributes are verified in TSC's material declarations and supported by third-party test reports available upon request. HS3B R7G is qualified for use in consumer, enterprise, and industrial products targeting EU, Japan, and South Korea environmental regulations.
What is the reverse recovery time (trr) specification for HS3B R7G?
The HS3B R7G has a maximum reverse recovery time (trr) of 50 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions. This fast recovery enables efficient operation in high-frequency switching converters (200–500 kHz), reducing switching losses and EMI generation compared to standard recovery diodes. The 50 ns trr is consistent across the full operating temperature range and contributes directly to improved system efficiency in telecom and server power supplies using HS3B R7G.
Is HS3B R7G suitable for automated SMT assembly?
Yes, HS3B R7G is fully optimized for automated surface-mount assembly. It carries J-STD-020 Moisture Sensitivity Level 1 (MSL-1), requiring no baking prior to reflow. Its DO-214AB (SMC) package features precise lead coplanarity and matte tin plating compatible with J-STD-002 solderability standards. The cathode band marking ensures reliable optical recognition during pick-and-place, and the 0.210 g weight prevents tombstoning in standard 250°C peak reflow profiles.
What is the forward voltage drop (VF) of HS3B R7G at rated current?
The HS3B R7G exhibits a maximum forward voltage drop (VF) of 1.0 V at 3 A and 25°C junction temperature, measured under pulse conditions (PW = 0.3 ms). This low VF directly reduces conduction losses-e.g., 3 W dissipation at full load versus >3.5 W for alternatives with VF ≥1.15 V-making HS3B R7G especially valuable in high-efficiency, thermally constrained applications like 5G infrastructure power modules and high-density server VRMs.
