Product details
Overview
HS3BB from Taiwan Semiconductor is a 3 A, 100 V surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring low forward voltage drop (1.0 V @ 3 A, 25°C), fast reverse recovery time (50 ns), and glass passivated junction for reliability in high-efficiency SMPS and adapters.
For engineers reviewing the HS3BB datasheet, HS3BB pinout, HS3BB application, or HS3BB equivalent, key selection criteria include repetitive peak reverse voltage (100 V), surge current capability (100 A), thermal resistance (60 °C/W), junction temperature range (–55 to +150 °C), and RoHS/halogen-free compliance for industrial power designs.
Technical Context
The HS3BB operates as a single-die, standard recovery rectifier optimized for switching-mode power supplies where moderate speed (50 ns trr) and low conduction loss balance efficiency and EMI. Its DO-214AA package supports automated placement and meets JESD201 Class 2 whisker resistance.
Thermal performance is defined by a junction-to-ambient thermal resistance of 60 °C/W under standard PCB mounting conditions, and its moisture sensitivity level is rated at Level 1 per J-STD-020 - eliminating bake requirements prior to reflow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum non-repetitive reverse voltage the device blocks without breakdown |
| IF | 3 A - continuous average forward current rating at 75°C case temperature |
| IFSM | 100 A - peak non-repetitive surge current (8.3 ms half-sine) for transient overload handling |
| VF @ 3A | 1.0 V - forward voltage drop at rated DC current, directly impacting conduction loss and thermal design |
| trr | 50 ns - reverse recovery time at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; determines switching loss in hard-switched topologies |
| RθJA | 60 °C/W - thermal resistance from junction to ambient on standard 1-inch² copper pad; used to calculate max junction temperature rise |

IC Role / Device Role / Timing Role: High-frequency rectification synchronized with PWM switching (50–200 kHz). Use Value: 50 ns trr ensures clean turn-off with minimal tail current, reducing MOSFET voltage overshoot. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR310 | Same 3 A / 100 V rating; trr = 50 ns; VF = 1.15 V @ 3 A - slightly higher conduction loss | Identical DO-214AA package; identical pinout and thermal profile | Preferred where tighter VF distribution or alternate supply chain is required |
| Vishay VS-3EWH10FN-M3 | 3 A / 100 V; trr = 35 ns (faster); VF = 0.92 V @ 3 A - lower loss but higher cost | DO-214AB (SMC) package - larger footprint and 0.25 mm taller; requires layout change | Select when faster recovery is critical and board space allows SMC footprint |
Compared with MUR310 and VS-3EWH10FN-M3, the HS3BB offers the lowest VF among SMB-packaged 100 V rectifiers in its family, balancing speed, size, and thermal performance for cost-sensitive industrial and consumer power supplies.

Manufacturer
Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and discrete semiconductor manufacturer headquartered in Hsinchu, Taiwan, serving global power, automotive, and industrial markets since 1979.
The HS3BB belongs to TSC's HS3x series of high-efficiency surface-mount rectifiers, designed specifically for compact, high-density AC-DC and DC-DC power conversion where low VF, fast trr, and robust thermal behavior are prioritized over ultra-fast recovery.
FAQ
What is the maximum junction temperature rating for HS3BB?
The HS3BB has a maximum junction temperature (TJ MAX) of +150°C, with an operational junction temperature range spanning –55°C to +150°C. This rating enables reliable operation in enclosed power supplies and thermally constrained environments when derated per the forward current derating curve. Thermal design must ensure the actual junction temperature stays within this limit under worst-case load and ambient conditions for the HS3BB.
Is HS3BB compatible with lead-free reflow soldering processes?
Yes, the HS3BB features matte tin-plated leads qualified per J-STD-002 for solderability and is rated for lead-free reflow profiles including JEDEC J-STD-020. Its moisture sensitivity level is Level 1, meaning it can be mounted directly from tape-and-reel without baking - simplifying manufacturing and ensuring robust intermetallic formation during Pb-free reflow for the HS3BB.
How does the reverse recovery time (trr) of HS3BB affect its use in high-frequency SMPS?
The HS3BB specifies trr = 50 ns under standard test conditions (IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A), making it suitable for SMPS operating up to ~200 kHz. At higher frequencies, tail current may increase switching losses; designers should verify waveform integrity and thermal margin in their specific topology. This trr value is confirmed in the HS3BB datasheet and applies directly to the HS3BB part number.
What is the marking code printed on the HS3BB device body?
The HS3BB is marked with "HS3BB" on its package surface, per the manufacturer's marking diagram. The marking includes the part number prefix "HS3", voltage code "B" (denoting 100 V), and suffix "B" (indicating standard version). No additional date or factory codes are required for identification of the HS3BB itself.
Does HS3BB have a specified junction capacitance, and how is it relevant?
Yes, the HS3BB has a typical junction capacitance (CJ) of 80 pF at 1 MHz and VR = 4.0 V, per the electrical specifications table. This parameter influences high-frequency noise coupling and snubber design in fast-switching circuits. It is measured and guaranteed for the HS3BB and differs from higher-voltage variants (e.g., HS3MB = 50 pF), confirming voltage-dependent junction area scaling in the HS3x family.
