Product details
Overview
HS3MB R5G from Taiwan Semiconductor is a 3 A, 1000 V high-efficiency surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring 1.7 V max forward voltage at 3 A and 75 ns reverse recovery time, used in high-voltage SMPS secondary-side rectification.
For engineers reviewing the HS3MB R5G datasheet, HS3MB R5G pinout, HS3MB R5G application, or HS3MB R5G equivalent, key selection criteria include peak repetitive reverse voltage rating, forward voltage drop under load, thermal resistance, junction capacitance, and surge current capability in compact SMB footprint.
Technical Context
This device is a single-die, glass-passivated, fast-recovery rectifier optimized for high-frequency switching applications. Its 1000 V VRRM, 100 A IFSM, and 75 ns trr support robust operation in offline AC/DC converters with minimal switching loss.
The DO-214AA (SMB) package delivers 60 °C/W junction-to-ambient thermal resistance and supports automated placement. Moisture sensitivity level 1 (J-STD-020) and halogen-free construction per IEC 61249-2-21 ensure reliability in reflow-soldered industrial assemblies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Withstands peak reverse voltage up to 1000 V without breakdown in high-line SMPS designs. |
| IF | 3 A continuous - Rated average forward current suitable for 36–60 W adapter output stages. |
| VF @ 3 A | ≤1.7 V - Low conduction loss improves efficiency and reduces heatsink requirements in 12–24 V output rails. |
| trr | ≤75 ns - Fast recovery minimizes switching losses and EMI in 65–130 kHz flyback and LLC topologies. |
| CJ @ 4 V | 50 pF - Low junction capacitance reduces capacitive coupling and improves high-frequency noise immunity. |
| RθJA | 60 °C/W - Enables 3 A operation at ≤100 °C ambient on standard 1 oz copper PCBs without forced air. |
| IFSM | 100 A - Handles 8.3 ms half-sine surges common during cold-start or line transients in universal-input supplies. |

Applications
| SMPS Secondary Rectification | AC/DC Adapters |
|---|---|

IC Role / Device Role / Timing Role: Main power conversion element delivering low-loss DC output after transformer isolation. Use Value: 75 ns trr and 50 pF CJ reduce switching node ringing and EMI filter size versus standard FR-type diodes. |
| Flat Panel TV Power Supply | Monitor Standby Converter |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600 V VRRM, 1.15 V VF @ 3 A, 50 ns trr, same SMB package | Limited to ≤600 V systems; lower VF improves light-load efficiency but insufficient for 1000 V designs | Select when system peak reverse voltage ≤600 V and faster recovery is prioritized over voltage rating. |
| ON Semi MUR3100E | 1000 V VRRM, 1.75 V VF @ 3 A, 100 ns trr, DO-214AA package | Slower recovery increases switching loss in >100 kHz designs; otherwise pin-compatible and functionally aligned | Choose where cost sensitivity outweighs 25 ns trr penalty and layout reuse is critical. |
Compared with STTH3L06S and MUR3100E, HS3MB R5G uniquely balances 1000 V rating, 75 ns recovery, and 1.7 V forward drop in SMB-making it optimal for compact, high-frequency, high-voltage SMPS where both voltage margin and switching efficiency are constrained.

FAQ
What is the maximum junction temperature rating for HS3MB R5G?
The HS3MB R5G has a maximum junction temperature (TJMAX) of +150 °C, enabling reliable operation in thermally demanding environments such as enclosed TV power supplies or industrial SMPS without derating below 3 A at ambient temperatures up to 100 °C. This rating is validated per JEDEC test conditions and supported by its 60 °C/W thermal resistance.
Does HS3MB R5G meet RoHS and halogen-free requirements?
Yes, HS3MB R5G is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and all terminals are matte tin-plated to meet J-STD-002 solderability standards-ensuring compatibility with lead-free reflow processes and environmental regulations for consumer electronics.
What is the reverse recovery time specification for HS3MB R5G?
The HS3MB R5G 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 fast recovery characteristic reduces switching losses and EMI generation in high-frequency flyback and resonant converters, distinguishing it from standard recovery rectifiers with trr > 200 ns.
Is HS3MB R5G suitable for use in automotive applications?
No, HS3MB R5G is not qualified for automotive applications. Taiwan Semiconductor explicitly states that its products-including the HS3x series-are not designed for medical, life-saving, or life-sustaining applications, and no AEC-Q101 qualification data is published for HS3MB R5G. It is intended for industrial, consumer, and computing power supplies only.
What does the 'R5G' suffix indicate in HS3MB R5G?
The 'R5G' suffix in HS3MB R5G denotes tape-and-reel packaging: 'R' indicates reel format, '5' specifies 3,000 units per reel, and 'G' signifies green (halogen-free) compound per IEC 61249-2-21. This matches the ordering code structure defined in Taiwan Semiconductor's documentation for the HS3x family.
