Product details
Overview
HS3B from Taiwan Semiconductor is a 3 A, 100 V high-efficiency surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring glass-passivated junction, low forward voltage drop (1.0 V @ 3 A, 25°C), and 150 A peak surge current capability; used in freewheeling and switching-mode power supplies for telecom and computing systems.
For engineers reviewing the HS3B datasheet, HS3B pinout, HS3B application, or HS3B equivalent, key selection criteria include repetitive peak reverse voltage (100 V), forward voltage at rated current, thermal resistance (60 °C/W), reverse recovery time (≤50 ns), and moisture sensitivity level (J-STD-020 Level 1).
Technical Context
The HS3B is a single-die, standard-recovery silicon rectifier optimized for high-frequency switching applications up to several hundred kHz. Its glass-passivated junction ensures stable reverse leakage (<10 µA @ 25°C) and robust thermal performance across -55°C to +150°C junction temperature range.
Designed for automated SMT placement, the DO-214AB (SMC) package supports 3,000-unit tape-and-reel delivery and meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance requirements; polarity is marked by cathode band on the molded case.
Key Specifications

| IF | 3 A - Continuous average forward current; determines heatsink sizing and PCB copper area requirements |
| VF @ 3 A, 25°C | 1.0 V - Forward voltage drop directly impacts conduction loss and system efficiency at full load |
| IFSM | 150 A - Non-repetitive surge rating; enables survival during startup inrush or transient overloads |
| trr | ≤50 ns - Reverse recovery time affects switching losses and EMI in high-frequency converters |
| RθJA | 60 °C/W - Junction-to-ambient thermal resistance; used with power dissipation to estimate max ambient temperature |
| CJ @ 1 MHz, 4 V | 80 pF - Junction capacitance influences high-frequency noise coupling and snubber design |
Pinout & Package
DO-214AB (SMC) surface-mount package with axial lead configuration: cathode indicated by band; matte tin-plated leads compliant with J-STD-002 solderability; weight ≈0.210 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck converter); must handle full IF and IFSM |
| Cathode | Forward current exit / reverse blocking terminal | Connected to higher-potential rail (e.g., output capacitor positive); marked by visible band; carries return current and blocks VR |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable IR <10 µA @ 25°C and long-term reliability under humid conditions without hermetic sealing |
| Low-profile DO-214AB (SMC) | 10.29 mm × 7.11 mm footprint with 2.41 mm height - fits compact power stages and enables automated pick-and-place |
| J-STD-020 Level 1 moisture sensitivity | No bake requirement prior to reflow - reduces manufacturing overhead and eliminates moisture-induced popcorning |
| RoHS & halogen-free compliance | Meets IEC 61249-2-21 and EU RoHS directives - supports green electronics certification and export compliance |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S (STMicroelectronics) | Same 3 A / 600 V rating but higher VF (1.7 V @ 3 A); TO-277 package (smaller footprint than DO-214AB) | Higher conduction loss limits use to lower-duty-cycle or lower-current applications | Select when space-constrained layout favors TO-277 and 600 V isolation is required over 100 V |
| MBR3100CT (ON Semiconductor) | 3 A / 100 V Schottky; VF = 0.85 V @ 3 A but IR = 100 µA @ 25°C (vs. HS3B's 10 µA) | Lower VF improves efficiency but higher leakage limits use in high-temperature or high-reliability reverse-bias hold-off | Select when efficiency dominates and ambient temperature stays below 85°C; avoid in >100°C environments or precision hold-off circuits |
Compared with STTH3L06S and MBR3100CT, the HS3B offers optimal balance of low VF (1.0 V), ultra-low IR (10 µA), and rugged DO-214AB packaging-making it preferred for cost-sensitive, thermally demanding, and reliability-critical 100 V rectification where Schottky leakage or higher-voltage silicon trade-offs are unacceptable.

FAQ
What is the maximum junction temperature rating for the HS3B?
The HS3B has a maximum junction temperature (TJ) rating of +150°C, with a minimum of -55°C. This wide operating range allows reliable deployment in enclosed industrial power supplies and under-hood automotive applications where ambient temperatures exceed 100°C. The device's thermal resistance (RθJA = 60 °C/W) enables accurate junction temperature estimation using measured power dissipation and board-level thermal design.
Does the HS3B have a specified reverse recovery time, and how is it measured?
Yes, the HS3B has a maximum reverse recovery time (trr) of 50 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per JEDEC test methodology. This value reflects its suitability for high-frequency switching applications up to ~500 kHz, where faster recovery reduces switching losses and EMI compared to general-purpose rectifiers.
Is the HS3B RoHS and halogen-free compliant?
Yes, the HS3B is fully RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound and matte tin-plated leads meet environmental regulations for restricted substances, supporting compliance in consumer, telecom, and industrial end products sold in EU, China, and other regulated markets.
What is the marking code and polarity indication for the HS3B?
The HS3B is marked "HS3B" on the device body, with polarity indicated by a distinct cathode band near one end of the DO-214AB (SMC) package. This band identifies the cathode terminal, which must be connected to the higher-potential node in the circuit to ensure proper forward conduction and reverse blocking behavior.
What is the moisture sensitivity level (MSL) and reflow profile requirement for the HS3B?
The HS3B is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and requires no baking prior to reflow soldering. It is qualified for standard Pb-free reflow profiles with peak temperatures up to 260°C, simplifying manufacturing and eliminating moisture-related yield loss in high-volume SMT assembly.
