Product details
Overview
HS5G R7G from Taiwan Semiconductor is a 400V, 5A surface-mount high-efficiency fast recovery rectifier in DO-214AB (SMC) package, featuring 1.30V max forward voltage at 5A/25°C, 50ns reverse recovery time, and glass-passivated junction for reliability in switching-mode power supplies.
For engineers reviewing the HS5G R7G datasheet, HS5G R7G pinout, HS5G R7G application, or HS5G R7G equivalent, this device serves as a critical freewheeling and output rectification component in telecom DC/DC converters, server VRMs, and industrial SMPS where low conduction loss and fast switching are required.
Technical Context
The HS5G R7G implements a single-die silicon PN junction structure with glass passivation for enhanced moisture resistance and thermal stability. Its 400V repetitive peak reverse voltage (VRRM) and 150A non-repetitive surge rating support robust operation in transient-prone power rails.
Designed for high-frequency operation, it delivers 50ns reverse recovery time (trr) under IF = 0.5A / IR = 1.0A conditions and exhibits 80pF junction capacitance at 1MHz/4V, enabling efficient performance in 100–500kHz switching topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum repetitive reverse blocking voltage; defines safe operating range in flyback/freewheeling paths |
| IF | 5 A - Continuous average forward current; supports 60W–100W output stages with appropriate heatsinking |
| VF (max) | 1.30 V @ 5A, 25°C - Directly impacts conduction loss; yields ~6.5W dissipation at full load |
| trr | 50 ns - Enables use in >200kHz converters without excessive switching loss or EMI from tail current |
| RθJA | 60 °C/W - Junction-to-ambient thermal resistance; requires ≥100mm² copper pad for 5A continuous operation at 70°C ambient |
| CJ | 80 pF @ 1MHz, 4V - Limits high-frequency displacement current; affects snubber design in resonant topologies |

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-5EWH04-M3 | Same DO-214AB package; 400V VRRM, 1.25V VF @ 5A, 35ns trr - faster but higher cost | Better suited for >400kHz resonant converters where trr dominates losses | Select when optimizing for ultra-high-frequency efficiency over cost |
| ON Semiconductor MUR540G | DO-214AC (SMA) package; same 400V/5A rating but 1.3V VF and 60ns trr; smaller footprint | Limited thermal mass - unsuitable for sustained 5A without aggressive copper pour | Choose only for space-constrained designs with <3A average current |
Compared with VS-5EWH04-M3 and MUR540G, the HS5G R7G offers balanced trade-offs: lower cost than Vishay's ultra-fast variant and superior thermal capability versus ON's SMA alternative, making it optimal for mainstream 200–300kHz industrial and telecom SMPS.

FAQ
What is the maximum junction temperature rating for HS5G R7G?
The HS5G R7G has a maximum junction temperature (TJ MAX) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet Version K2102. This rating enables reliable operation in enclosed industrial power supplies where ambient temperatures reach 70–85°C, provided thermal design meets the 60°C/W RθJA specification using adequate PCB copper area.
Does HS5G R7G have RoHS and halogen-free compliance?
Yes, HS5G R7G is RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in the "Features" section of the Taiwan Semiconductor datasheet. The molding compound is UL 94V-0 rated, and terminals are matte tin-plated to meet J-STD-002 solderability standards - critical for lead-free reflow processes in automotive and industrial assembly lines.
What is the reverse recovery time (trr) specification for HS5G R7G?
The HS5G R7G has a reverse recovery time (trr) of 50 ns, measured under IF = 0.5A, IR = 1.0A, and Irr = 0.25A conditions per the Electrical Specifications table in the official datasheet. This value is confirmed for all HS5G variants and supports stable operation in 200–400kHz switching converters without excessive switching loss or EMI generation.
Is HS5G R7G pin-compatible with other devices in the HS5x family?
Yes, all HS5x devices-including HS5G R7G-share identical DO-214AB (SMC) package dimensions, pinout, and cathode band marking. Voltage ratings differ (e.g., HS5A = 50V, HS5M = 1000V), but mechanical and thermal interface requirements remain consistent across the family, simplifying board-level voltage scalability.
What is the forward voltage drop of HS5G R7G at rated current?
The HS5G R7G exhibits a maximum forward voltage drop (VF) of 1.30 V at 5A and 25°C, as specified in the Electrical Specifications table. At 3A and 25°C, VF is not explicitly stated in the datasheet, but typical values fall below 1.15 V - a key parameter for calculating conduction losses in high-current power stage design.
