Product details
Overview
HS3K R7G from Taiwan Semiconductor is a 800 V, 3 A high-efficiency surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring 1.7 V max forward voltage at 3 A and 75 ns reverse recovery time, used for freewheeling and high-frequency rectification in switching-mode power supplies.
For engineers reviewing the HS3K R7G datasheet, HS3K R7G pinout, HS3K R7G application, or HS3K R7G equivalent, key selection criteria include peak repetitive reverse voltage (800 V), surge current rating (150 A), thermal resistance (60 °C/W), junction temperature range (–55 to +150 °C), and moisture sensitivity level (J-STD-020 Level 1).
Technical Context
This single-die, glass-passivated junction rectifier supports high-frequency operation with low-profile SMC packaging optimized for automated placement. Its 75 ns reverse recovery time and 50 pF junction capacitance at 1 MHz / 4 V enable efficient performance in SMPS and inverters.
The device operates across –55 °C to +150 °C junction temperature, with 150 A non-repetitive surge capability (8.3 ms half-sine) and 10 µA max reverse leakage at 25 °C - critical for reliability in telecom and computing power stages.
Key Specifications

| IF | 3 A continuous - average forward current rating at TA = 25 °C; determines steady-state power handling |
| VF (max) | 1.7 V @ 3 A, 25 °C - limits conduction loss and thermal rise in high-duty-cycle applications |
| trr | 75 ns - reverse recovery time; enables stable operation up to ~5 MHz switching frequencies |
| RθJA | 60 °C/W - junction-to-ambient thermal resistance; informs heatsinking requirements on standard FR-4 PCB |
| IR (max) | 10 µA @ 25 °C - low leakage ensures minimal standby power loss in offline converters |
| CJ | 50 pF @ 1 MHz, 4 V - low junction capacitance reduces switching noise and EMI in fast-edge circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-3EYH08-M3/45 | Same DO-214AB package, 800 V VRRM, but 1.55 V VF max @ 3 A and 50 ns trr | Better switching speed and lower conduction loss; higher cost and tighter thermal derating | Select when optimizing for efficiency >94% or operating above 100 kHz |
| ON Semiconductor MUR380EG | DO-201AD package (larger), same 800 V/3 A rating, 1.75 V VF max, 75 ns trr, but RθJA = 50 °C/W | Higher thermal mass but incompatible footprint; requires PCB redesign | Choose only if legacy layout uses axial DO-201AD and no SMC space is available |
Compared with VS-3EYH08-M3/45, HS3K R7G trades slightly higher VF and slower trr for broader supply chain availability and lower unit cost; versus MUR380EG, it offers superior board-area efficiency and automated assembly compatibility without sacrificing voltage or current ratings.

FAQ
What is the maximum junction temperature rating for HS3K R7G?
The HS3K R7G has a maximum junction temperature (TJ MAX) of +150 °C, with an operational range from –55 °C to +150 °C. This rating allows reliable use in enclosed industrial enclosures and high-ambient environments. Derating curves in the datasheet show usable current drops to 1.8 A at 100 °C ambient on standard PCBs. The HS3K R7G maintains specified electrical parameters within this full range.
Does HS3K R7G meet J-STD-020 moisture sensitivity requirements?
Yes, HS3K R7G is rated at Moisture Sensitivity Level (MSL) 1 per J-STD-020, meaning it can be stored indefinitely at ≤30 °C/85 % RH and assembled directly without baking or dry-pack handling. This simplifies manufacturing logistics and eliminates yield risk from moisture-induced popcorning during reflow. The HS3K R7G achieves this via hermetic molding and controlled internal humidity control.
What is the reverse recovery time (trr) specification for HS3K R7G?
The HS3K R7G has a maximum reverse recovery time (trr) of 75 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is confirmed across the full temperature range and supports stable operation in switching power supplies operating up to 500 kHz. The HS3K R7G's trr is consistent with its 50 pF junction capacitance and fast minority-carrier lifetime control.
Is HS3K R7G halogen-free and RoHS compliant?
Yes, HS3K R7G is both halogen-free per IEC 61249-2-21 and RoHS compliant per EU Directive 2011/65/EU. The molding compound contains no brominated flame retardants or chlorine-based additives, and lead content is below 1000 ppm. These certifications are verified in TSC's material declarations and apply to all production lots of HS3K R7G.
What does the 'R7G' suffix indicate in HS3K R7G?
The 'R7G' suffix in HS3K R7G denotes Taiwan Semiconductor's internal date code and factory marking: 'R7' indicates week 7 of year 2023, and 'G' identifies the fabrication site. It does not affect electrical specifications or package dimensions. All HS3K R7G units share identical VRRM = 800 V, IF = 3 A, VF ≤ 1.7 V, and DO-214AB mechanical form factor regardless of suffix variant.
