Product details
Overview
HS3GB from Taiwan Semiconductor is a 400 V repetitive peak reverse voltage, 3 A average forward current, surface-mount fast recovery rectifier in DO-214AA (SMB) package, with 1.3 V max forward voltage at 3 A and 50 ns reverse recovery time-used in SMPS secondary-side rectification and AC/DC adapters.
For engineers reviewing the HS3GB datasheet, HS3GB pinout, HS3GB application, or HS3GB equivalent, key selection criteria include VR(RMS) = 280 V, junction capacitance = 80 pF at 1 MHz / VR = 4.0 V, thermal resistance RθJA = 60 °C/W, and moisture sensitivity level 1 compliance for high-volume automated assembly.
Technical Context
The HS3GB employs a single-die, glass-passivated silicon junction optimized for fast switching in high-frequency power conversion. Its 50 ns trr and low VF support efficiency in 50–500 kHz SMPS topologies while maintaining robust surge capability (IFSM = 100 A).
Designed for DO-214AA (SMB) footprint compatibility, it operates across -55°C to +150°C junction temperature range and meets JESD201 Class 2 whisker resistance and RoHS/halogen-free requirements per IEC 61249-2-21.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - supports input rectification up to 280 V RMS line voltage in universal-input adapters |
| IF(AV) | 3 A - sustains continuous output current in 30–60 W offline SMPS designs |
| VF(max) | 1.3 V @ 3 A, 25°C - reduces conduction loss vs. standard FRDs, improving efficiency at light-to-moderate loads |
| trr | 50 ns - enables stable operation in 200–500 kHz flyback and forward converters without excessive switching loss |
| CJ | 80 pF @ 1 MHz, VR = 4.0 V - limits capacitive coupling noise in high dv/dt gate-drive or snubber circuits |
| RθJA | 60 °C/W - allows 3 A operation with ≤75°C ambient rise on standard 1-in² 2-oz copper pad |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L04 | 400 V VRRM, 3 A IF, VF = 1.35 V, trr = 45 ns, DO-214AA | Slightly faster trr but higher VF; same thermal resistance | Preferred where minimal turn-off loss dominates over conduction loss |
| ON Semi MUR340 | 400 V VRRM, 3 A IF, VF = 1.3 V, trr = 60 ns, DO-214AA | Slower recovery but identical VF and package; higher IR spec (50 μA) | Selected when lower leakage is critical in high-impedance bias networks |
Compared with STTH3L04 and MUR340, the HS3GB offers balanced trade-offs: identical VRRM/IF and VF to MUR340 but 10 ns faster recovery, and lower VF than STTH3L04 at equal trr-making it optimal for cost-sensitive, thermally constrained 30–50 W SMPS designs.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) rating for HS3GB?
The HS3GB has a VRRM rating of 400 V, verified in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version L2102). This allows safe operation with up to 280 V RMS input voltage in bridge rectifier configurations. The HS3GB must not be subjected to reverse voltages exceeding this limit to prevent junction breakdown or premature failure.
What is the forward voltage drop (VF) of HS3GB at rated current?
The HS3GB exhibits a maximum forward voltage of 1.3 V at 3 A and 25°C junction temperature, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents worst-case conduction loss for thermal design. At elevated temperatures, VF decreases slightly due to semiconductor physics, but derating curves confirm usable margin up to 150°C TJ.
Does HS3GB have a defined reverse recovery time (trr), and how is it measured?
Yes, the HS3GB has a specified reverse recovery time of 50 ns maximum, tested under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per JEDEC standards. This parameter is critical for minimizing switching losses in high-frequency SMPS. The HS3GB's trr is confirmed in the Electrical Specifications table and validated via the test circuit diagram shown in Figure 6 of the datasheet.
What package type does HS3GB use, and what are its key mechanical features?
The HS3GB uses the DO-214AA (SMB) surface-mount package, with matte tin-plated leads compliant with J-STD-002, UL 94V-0 molding compound, and polarity indicated by a cathode band. Its 0.093 g weight and low-profile form factor support automated placement and thermal management on standard PCB pads, as documented in the Mechanical Data section of the HS3GB datasheet.
Is HS3GB compliant with environmental and reliability standards?
Yes, the HS3GB is RoHS compliant and halogen-free per IEC 61249-2-21. It carries moisture sensitivity level 1 per J-STD-020, eliminating pre-bake requirements, and passes JESD201 Class 2 whisker testing. These qualifications are explicitly stated in the Features and Mechanical Data sections of the Taiwan Semiconductor HS3GB datasheet (Version L2102).
