Product details
Overview
HS3G R7G from Taiwan Semiconductor is a 400 V repetitive peak reverse voltage, 3 A average forward current, surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring 1.3 V max forward voltage at 3 A and 50 ns max reverse recovery time - used for high-frequency freewheeling and output rectification in switching-mode power supplies.
For engineers reviewing the HS3G R7G datasheet, HS3G R7G pinout, HS3G R7G application, or HS3G R7G equivalent, key selection criteria include VRRM = 400 V, IF = 3 A, VF ≤ 1.3 V @ 3 A, trr ≤ 50 ns, and DO-214AB thermal resistance of 60 °C/W - critical for compact, high-efficiency AC/DC and DC/DC converters.
Technical Context
This device is a single-die, glass-passivated, standard recovery silicon rectifier optimized for high-frequency operation up to several hundred kHz. Its low trr (≤50 ns) and low VF enable reduced switching losses in flyback and forward converter secondary-side rectification.
The DO-214AB (SMC) package provides robust thermal performance (RθJA = 60 °C/W) and moisture sensitivity level 1 handling, supporting automated SMT placement without baking. Polarity is marked by a cathode band on the body.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum non-repetitive reverse voltage the diode blocks reliably in circuit |
| IF(AV) | 3 A - continuous average forward current rating at TC = 75°C, defining steady-state power handling |
| VF | ≤1.3 V @ 3 A, 25°C - forward conduction loss directly impacts efficiency and thermal rise in high-current paths |
| trr | ≤50 ns - fast recovery enables use in >100 kHz SMPS without excessive switching loss or ringing |
| RθJA | 60 °C/W - junction-to-ambient thermal resistance under standard PCB mounting, guiding heatsinking requirements |
| CJ | 80 pF @ 4 V - junction capacitance affects high-frequency noise coupling and snubber design |
| IFSM | 150 A - peak surge current capability for handling inrush or transient overloads without failure |
Pinout & Package

Applications
| Server PSU Output Rectification | Telecom DC/DC Converter Freewheeling |
|---|---|
Use Scenario: Secondary-side rectification in 48 V input, 12 V/30 A isolated DC/DC modules for data center servers. IC Role / Device Role / Timing Role: Power rectifier converting high-frequency transformer output to regulated DC, operating continuously at 3 A. Use Value: 1.3 V VF minimizes conduction loss; 50 ns trr suppresses switching noise and reduces snubber size. | Use Scenario: Freewheeling path in synchronous buck-derived telecom POL converters (e.g., 48 V → 3.3 V). IC Role / Device Role / Timing Role: Uncontrolled rectifier providing current continuity during high-side MOSFET off-time. Use Value: Fast recovery avoids reverse conduction overlap; DO-214AB footprint supports automated assembly in high-volume production. |

Use Scenario: Output rectification in compact 65 W flyback adapters powering ultrabooks. IC Role / Device Role / Timing Role: Main power diode conducting full-load current at ~100–200 kHz switching frequency. Use Value: Low VF improves light-load efficiency; 400 V VRRM provides margin above reflected output voltage spikes. | Use Scenario: Auxiliary bias supply rectifier in 3 kW industrial inverters, powering gate drivers and control logic. IC Role / Device Role / Timing Role: Isolated auxiliary rectifier delivering 15 V/0.5 A from auxiliary winding. Use Value: 150 A IFSM withstands startup surges; 150 °C TJ max ensures operation in high-ambient environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L04S | VRRM = 400 V, VF = 1.25 V @ 3 A, trr = 45 ns, same DO-214AB package | Slightly faster recovery and lower VF; tighter parameter distribution per batch | Preferred where <45 ns trr or tighter VF consistency is required in high-volume telecom designs |
| ON Semi MUR340 | VRRM = 400 V, VF = 1.3 V @ 3 A, trr = 50 ns, DO-214AB package | Identical electrical specs; different marking and qualification history (AEC-Q101 not claimed) | Drop-in alternative when sourcing diversification or legacy BOM alignment is needed |
Compared with STTH3L04S and MUR340, HS3G R7G offers identical VRRM, IF, VF, and trr ratings in DO-214AB, but differs in JEDEC-compliant moisture sensitivity level 1 handling and halogen-free construction - advantageous for RoHS-critical, high-reliability industrial programs.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for HS3G R7G?
The HS3G R7G has a VRRM rating of 400 V, meaning it can reliably block up to 400 V of reverse voltage in repetitive applications without breakdown. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version K2102), and aligns with the 'G' suffix in the HS3x family designation.
What is the forward voltage drop of HS3G R7G at rated current?
The HS3G R7G exhibits a maximum forward voltage drop of 1.3 V at 3 A forward current and 25°C junction temperature. This value is specified in the Electrical Specifications table under "Forward voltage" for the HS3G variant, and reflects typical conduction loss under standard test conditions (pulse width = 0.3 ms).
Does HS3G R7G have a defined reverse recovery time (trr)?
Yes, the HS3G R7G has a maximum reverse recovery time of 50 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter is explicitly listed in the Electrical Specifications section of the Taiwan Semiconductor datasheet and confirms its suitability for high-frequency switching applications up to several hundred kHz.
What package type does HS3G R7G use, and what are its key mechanical features?
HS3G R7G uses the DO-214AB (SMC) surface-mount package. Key mechanical features include matte tin-plated leads compliant with J-STD-002, UL 94V-0 molding compound, polarity indicated by cathode band, and moisture sensitivity level 1 per J-STD-020 - enabling direct placement without pre-baking.
Is HS3G R7G RoHS and halogen-free compliant?
Yes, HS3G R7G is RoHS compliant and halogen-free per IEC 61249-2-21. This is stated in both the Features and Mechanical Data sections of the official Taiwan Semiconductor datasheet (Version K2102), confirming its suitability for environmentally regulated industrial and telecom end equipment.
