Product details
Overview
HS3DB from Taiwan Semiconductor is a 3 A, 200 V repetitive peak reverse voltage (VRRM) surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring 1.0 V max forward voltage at 3 A and 50 ns reverse recovery time - deployed in switching mode power supplies and AC/DC adapters for high-efficiency energy conversion.
For engineers reviewing the HS3DB datasheet, HS3DB pinout, HS3DB application, or HS3DB equivalent, key selection criteria include its 200 V VRRM, 100 A IFSM, 150 °C maximum junction temperature, DO-214AA mechanical compatibility, and low-profile SMB footprint for automated SMT assembly in compact power converters.
Technical Context
This is a single-die, glass-passivated, fast-recovery rectifier optimized for high-frequency switching applications. Its 50 ns trr and 80 pF junction capacitance support efficient operation in 50–500 kHz SMPS topologies while maintaining low conduction loss via 1.0 V VF at rated current.
The device operates across –55 °C to +150 °C junction temperature range and exhibits 10 μA max reverse leakage at 25 °C, enabling stable performance in thermally constrained environments such as enclosed adapters and flat-panel TV power stages.
Key Specifications

| IF | 3 A continuous - delivers sufficient output current for mid-power SMPS (e.g., 36 W @ 12 V) |
| VF @ 3 A | ≤1.0 V - reduces conduction loss to ≤3 W at full load, improving thermal management |
| trr | ≤50 ns - enables clean turn-off in high-frequency flyback and forward converters |
| RθJA | 60 °C/W - allows 3 A operation on standard 1-in² copper pad without forced air |
| Junction capacitance | 80 pF @ 4 V - minimizes capacitive switching loss and EMI generation |
| IFSM | 100 A (8.3 ms) - withstands inrush surges during cold-start of AC/DC supplies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L02 | 200 V VRRM, 3 A IF, 1.15 V VF @ 3 A, 55 ns trr, TO-220AC package | Larger through-hole footprint; higher VF increases conduction loss by ~0.45 W | Preferred where board space permits and thermal mass supports TO-220 mounting |
| ES3D | 200 V VRRM, 3 A IF, 1.05 V VF @ 3 A, 35 ns trr, DO-214AA package | Faster recovery but higher cost; identical SMB footprint and polarity marking | Selected when <40 ns trr is required for >400 kHz resonant designs |
Compared with STTH3L02 and ES3D, the HS3DB offers optimal balance of low VF, fast trr, SMB compatibility, and cost for mainstream 100–250 kHz SMPS - making it ideal for volume production of adapters and monitors where layout density and thermal budget are constrained.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) rating for HS3DB?
The HS3DB has a maximum repetitive peak reverse voltage (VRRM) of 200 V, as confirmed in the Absolute Maximum Ratings table on page 1 of the L2102 datasheet. This rating defines the highest instantaneous reverse voltage the HS3DB can block repeatedly without breakdown under normal operating conditions, making it suitable for 141 V RMS AC inputs with appropriate derating.
Does HS3DB have a specified reverse recovery time (trr) and what is its value?
Yes, the HS3DB has a specified reverse recovery time (trr) of ≤50 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, per the Electrical Specifications table. This fast trr value is critical for minimizing switching losses in high-frequency SMPS designs using the HS3DB.
What package type does HS3DB use and is it compatible with standard SMB footprints?
The HS3DB uses the DO-214AA (SMB) package, with standardized dimensions and lead pitch matching JEDEC MS-012. Its cathode band marking, matte tin-plated leads, and 2.62 mm max height ensure full compatibility with industry-standard SMB land patterns and reflow soldering profiles used for automated SMT assembly of the HS3DB.
What is the forward voltage (VF) of HS3DB at its rated 3 A current?
The forward voltage (VF) of the HS3DB is guaranteed to be ≤1.0 V at IF = 3 A and TJ = 25 °C, as stated in the Electrical Specifications table. This low VF directly contributes to reduced conduction losses and improved thermal performance when the HS3DB is used in high-current rectification paths.
Is HS3DB compliant with RoHS and halogen-free requirements?
Yes, the HS3DB is RoHS compliant and halogen-free in accordance with IEC 61249-2-21, as explicitly stated in the FEATURES section of the L2102 datasheet. These compliance statements apply to the HS3DB itself and are verified per Taiwan Semiconductor's material declarations and manufacturing controls.
