Product details
Overview
HS2BA from Taiwan Semiconductor is a 1.5A, 100V repetitive peak reverse voltage (VRRM) surface-mount fast recovery rectifier in DO-214AC (SMA) package, with forward voltage of 1.0 V at 1.5 A and reverse recovery time of 50 ns - used in DC/DC converters and snubber circuits for high-efficiency power conversion.
For engineers reviewing the HS2BA datasheet, HS2BA pinout, HS2BA application, or HS2BA equivalent, key selection criteria include its 100V VRRM, 50 ns trr, 1.0 V VF at rated current, DO-214AC thermal resistance (80 °C/W), and suitability for automated SMT assembly in compact power supplies.
Technical Context
The HS2BA employs a glass-passivated single-die silicon junction optimized for fast switching and low conduction loss. Its 50 ns reverse recovery time enables operation in high-frequency switching topologies up to several hundred kHz without excessive switching loss.
Thermal performance is defined by RθJA = 80 °C/W in standard JEDEC PCB mounting conditions, and it supports continuous forward current of 1.5 A with junction temperature limited to 150 °C - making it suitable for space-constrained, thermally demanding applications like LED drivers and AC-DC auxiliary supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum non-repetitive reverse blocking voltage; defines safe operating range in flyback or boost diode positions |
| IF | 1.5 A - average forward current rating; determines continuous power handling in rectification paths |
| VF @ 1.5 A | 1.0 V - forward voltage drop at rated current; directly impacts conduction loss and thermal rise in high-duty-cycle operation |
| trr | 50 ns - reverse recovery time; enables efficient operation in 100–500 kHz SMPS designs with minimal switching loss |
| RθJA | 80 °C/W - junction-to-ambient thermal resistance; sets minimum PCB copper area and airflow requirements for thermal management |
| IFSM | 50 A - peak surge current capability; withstands inrush and transient overloads in input rectification stages |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, low-profile plastic case with matte tin-plated leads; polarity indicated by cathode band.
| Pin/Terminal | Circuit Role | Design Meaning |

Use Value: 1.5 A IF rating and fast trr prevent voltage overshoot and ensure clean current decay in PWM-controlled loads. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06 | VRRM = 600 V, trr = 65 ns, VF = 1.15 V @ 1 A | Higher voltage rating but slower recovery and higher VF at lower current | Preferable where >100 V blocking is required, not a direct replacement for HS2BA's 100 V/50 ns operating point |
| MBR15100CT | Dual common-cathode Schottky, 100 V, 7.5 A per anode, VF = 0.85 V @ 7.5 A | Lower VF but higher leakage and no reverse recovery benefit; unsuitable for high-voltage snubbers | Only viable if system requires dual-output rectification and can tolerate higher IR at elevated temperature |
Compared with STTH1L06 and MBR15100CT, the HS2BA delivers optimal balance of 100 V blocking, 50 ns trr, and 1.0 V VF at 1.5 A - making it uniquely suited for compact, high-frequency 10–50 W DC/DC and lighting supplies where thermal and timing constraints are tight.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for HS2BA?
The HS2BA has a VRRM of 100 V, as specified in the Absolute Maximum Ratings table. This value defines the highest instantaneous reverse voltage the device can block repeatedly without breakdown. It is critical for selecting appropriate derating margins in applications such as output rectification in 12 V or 24 V DC/DC converters where transient spikes may approach this limit.
What is the forward voltage (VF) of HS2BA at its rated current?
The HS2BA exhibits a typical forward voltage of 1.0 V at 1.5 A and 25 °C junction temperature, per the Electrical Specifications table. This value directly influences conduction loss (Pcond = VF × IF) and must be evaluated alongside thermal resistance to ensure safe junction temperature in continuous operation.
Does HS2BA have a specified reverse recovery time (trr)?
Yes, the HS2BA has a maximum reverse recovery time of 50 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter confirms its classification as a fast recovery rectifier and supports use in switching frequencies up to 500 kHz without significant switching loss penalties.
What package type is used for HS2BA?
The HS2BA is housed in a DO-214AC (SMA) surface-mount package, as confirmed in both the Mechanical Data and Ordering Information sections. This package features matte tin-plated leads, complies with J-STD-002 solderability, and supports automated placement with standard SMT reflow profiles.
Is HS2BA compliant with RoHS and halogen-free standards?
Yes, HS2BA is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the Features section. These compliance statements apply to the HS2BA variant and are verified through TSC's material declarations and third-party testing reports for the DO-214AC packaged device.
