Product details
Overview
HS3KB R5G from Taiwan Semiconductor is a 3A, 400V repetitive peak reverse voltage (VRRM), surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring 1.7V max forward voltage at 3A and 75ns reverse recovery time, used in switching mode power supplies and AC/DC adapters.
For engineers reviewing the HS3KB R5G datasheet, HS3KB R5G pinout, HS3KB R5G application, or HS3KB R5G equivalent, key selection criteria include VRRM=400V, IF=3A, VF≤1.7V @3A, trr≤75ns, and SMB package compatibility with automated SMT assembly.
Technical Context
This is a single-die, glass-passivated, fast-recovery rectifier optimized for high-frequency switching applications. Its 75ns reverse recovery time and low junction capacitance (50pF @1MHz, VR=4V) support efficient operation in SMPS topologies operating up to several hundred kHz.
The device operates across -55°C to +150°C junction temperature range, with 60°C/W junction-to-ambient thermal resistance and moisture sensitivity level 1 (J-STD-020), enabling reliable reflow soldering and long-term thermal stability in compact power converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum non-repetitive reverse voltage the diode blocks without breakdown; defines usable input voltage range in bridge or output rectification. |
| IF | 3 A - Continuous average forward current rating; determines maximum DC output capability in linear derating down to zero at 150°C. |
| VF | ≤1.7 V @ 3A, 25°C - Forward voltage drop directly impacts conduction loss and thermal design; lower VF reduces I²R heating in high-current paths. |
| trr | ≤75 ns - Reverse recovery time governs switching loss and EMI generation during turn-off; critical for efficiency in >100kHz SMPS designs. |
| CJ | 50 pF @ 1MHz, VR=4V - Junction capacitance affects high-frequency impedance and snubber requirements; lower CJ improves high-speed switching behavior. |
| RθJA | 60 °C/W - Thermal resistance from junction to ambient under standard PCB conditions; used to calculate junction temperature rise for reliability margining. |
Pinout & Package
Package: DO-214AA (SMB), surface-mount, cathode indicated by band, matte tin-plated leads, UL 94V-0 molding compound, 0.093g weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of rectified path (e.g., transformer secondary center-tap or bridge leg input). |
| Cathode | Forward current exit point | Connected to higher-potential output node; polarity band identifies this terminal for correct PCB placement. |
Key Features
| Feature | Design Value |
|---|---|
| Fast recovery time | 75ns max enables high-frequency switching (>200kHz) with reduced turn-off loss and EMI compared to standard rectifiers. |
| Glass passivated junction | Enhances long-term reliability and leakage stability under humid or thermally cycling conditions in industrial environments. |
| Moisture sensitivity level 1 | Allows unlimited floor life before reflow; no baking required-reduces manufacturing overhead and avoids moisture-induced popcorning. |
| Halogen-free construction | Complies with IEC 61249-2-21; supports RoHS-compliant end-product certification and environmentally responsible supply chain requirements. |
Applications
| AC/DC Adapter Rectification | SMPS Output Stage |
|---|---|
Use Scenario: Secondary-side rectification in 12–24V, 36W wall adapters using flyback topology. IC Role / Device Role / Timing Role: Power rectifier converting high-frequency transformer output to regulated DC; handles 3A continuous output current.

IC Role / Device Role / Timing Role: Fast-recovery discrete rectifier replacing Schottky in cost-sensitive designs where 150°C operation is required. Use Value: 75ns trr and 400V VRRM provide safe margin against voltage spikes while maintaining thermal robustness up to 150°C junction. |
| Monitor Power Supply | TV Standby Converter |
Use Scenario: Main 12V rail rectification in LCD monitor auxiliary power stage operating at 65kHz. IC Role / Device Role / Timing Role: Primary output rectifier in quasi-resonant flyback supplying logic and backlight circuitry.

IC Role / Device Role / Timing Role: Low-leakage (≤10μA @25°C) rectifier minimizing quiescent current in always-on auxiliary winding circuits. Use Value: Ultra-low IR ensures standby power remains below regulatory thresholds (e.g., ENERGY STAR Tier 2) without compromising surge robustness. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L04 | VRRM=400V, IF=3A, VF=1.7V @3A, trr=70ns, DO-214AA | Slightly faster trr but higher VF variation across lot; same SMB footprint | Preferred where tighter trr tolerance is prioritized over VF consistency. |
| ES3D-E3/57T | VRRM=200V, IF=3A, VF=1.15V @3A, trr=35ns, DO-214AA | Lower VRRM and VF, faster recovery-but insufficient for 400V line-transient margin | Only suitable in 115VAC-only or low-VRRM designs; not a direct replacement for HS3KB R5G's 400V rating. |
Compared with STTH3L04 and ES3D-E3/57T, HS3KB R5G provides guaranteed 400V blocking with consistent 1.7V VF and 75ns trr in an MSL-1 SMB package-making it optimal for globally rated 230VAC-input adapters requiring robust transient immunity and process reliability.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for HS3KB R5G?
The HS3KB R5G has a VRRM rating of 400 V, meaning it reliably blocks reverse voltages up to this level without breakdown. This value is confirmed in the Absolute Maximum Ratings table on page 2 of the Taiwan Semiconductor HS3AB–HS3MB datasheet (Version L2102), and is marked as "HS3KB" in the voltage code matrix. The "KB" suffix explicitly denotes the 400V variant within the HS3x family.
What is the forward voltage drop (VF) specification for HS3KB R5G at rated current?
The HS3KB R5G exhibits a maximum forward voltage drop of 1.7 V at 3 A forward current and 25°C junction temperature, per the Electrical Specifications table. This value is consistent across the HS3JB/HS3KB/HS3MB group and reflects typical conduction loss under standard test conditions (pulse width = 0.3 ms). Real-world VF increases with temperature and current, following the curve in Figure 4 of the datasheet.
Does HS3KB R5G have a defined reverse recovery time (trr), and what is its value?
Yes, HS3KB R5G has a specified reverse recovery time of ≤75 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, as stated in the Electrical Specifications table. This trr value applies to the entire HS3JB/HS3KB/HS3MB subgroup and is measured at 25°C. It is validated in Figure 6, which shows the test circuit and waveform characteristics.
What package type and mounting style does HS3KB R5G use?
HS3KB R5G uses the DO-214AA (SMB) surface-mount package, as confirmed in the Mechanical Data section and Ordering Information table. It features matte tin-plated leads compatible with J-STD-002 soldering, a cathode band for polarity identification, and weighs approximately 0.093 g. The recommended pad layout and outline dimensions are provided on page 5 of the datasheet.
Is HS3KB R5G compliant with RoHS and halogen-free standards?
Yes, HS3KB R5G is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section of the datasheet. It also meets JESD 201 Class 2 whisker resistance and carries Moisture Sensitivity Level 1 per J-STD-020-enabling unlimited floor life and eliminating pre-reflow baking requirements.
