Product details
Overview
HS3JB from Taiwan Semiconductor is a 3A, 600V repetitive peak reverse voltage (VRRM), surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring 1.7V max forward voltage at 3A and 75ns reverse recovery time, used in high-efficiency SMPS secondary-side rectification.
For engineers reviewing the HS3JB datasheet, HS3JB pinout, HS3JB application, or HS3JB equivalent, key selection criteria include VRRM rating, VF vs. IF trade-off, trr for high-frequency operation, thermal resistance (RθJA = 60°C/W), and SMB package compatibility with automated assembly.
Technical Context
The HS3JB is a single-die, glass-passivated, fast-recovery rectifier optimized for switching-mode power supplies operating up to several hundred kHz. Its 600V VRRM rating and 100A IFSM surge capability support robust operation under transient overvoltage and inrush conditions.
With a typical junction capacitance of 50pF at 4V reverse bias and 75ns trr measured under IF = 0.5A / IR = 1.0A / Irr = 0.25A conditions, the HS3JB balances low switching loss and EMI control in compact AC/DC and DC/DC converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum non-repetitive reverse voltage the device blocks reliably in circuit |
| IF | 3 A - Continuous average forward current rating at TA = 25°C with proper PCB copper area |
| VF (max) | 1.7 V @ 3A, TJ = 25°C - Directly impacts conduction loss and thermal design in output rectification stage |
| trr | 75 ns - Enables efficient operation in 100–500 kHz SMPS without excessive switching loss or ringing |
| RθJA | 60 °C/W - Defines thermal derating slope; requires ≥1 cm² 2-oz copper pad for full 3A rating at 25°C ambient |
| CJ | 50 pF @ 1 MHz, VR = 4 V - Low capacitance reduces capacitive coupling noise and improves EMI performance |
| TJ max | 150 °C - Junction temperature limit enabling operation in enclosed or high-ambient industrial power supplies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S (STMicroelectronics) | Same 600V VRRM, 3A IF, but VF = 1.85V (max), trr = 60ns, TO-277 package | TO-277 has higher thermal mass but larger footprint than SMB; better for higher ambient temp | Select when lower trr is prioritized over VF and board space is available |
| ES3J (ON Semiconductor) | 600V VRRM, 3A IF, VF = 1.7V (max), trr = 75ns, same DO-214AA (SMB) package | Identical electrical specs and footprint; different marking and qualification history | Drop-in replacement with verified production history in consumer power supplies |
Compared with STTH3L06S, HS3JB offers lower VF and smaller SMB footprint but slightly slower trr; versus ES3J, HS3JB provides identical performance in same package with differentiated manufacturing traceability and J-STD-020 Level 1 moisture rating.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) rating for HS3JB?
The HS3JB has a VRRM rating of 600 V, meaning it can reliably block up to 600 volts of reverse voltage in repetitive applications such as AC line rectification or freewheeling paths. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version L2102) and is critical for ensuring safe operation under worst-case line transients in 230VAC systems.
What is the forward voltage drop (VF) specification for HS3JB at rated current?
The HS3JB exhibits a maximum forward voltage drop of 1.7 V at 3 A forward current and 25°C junction temperature. This parameter is measured under pulsed conditions (PW = 0.3 ms) and directly determines conduction loss in the output stage of power supplies. Lower VF contributes to improved efficiency and reduced thermal stress on the HS3JB and surrounding PCB copper.
Does HS3JB have a defined reverse recovery time (trr), and how is it measured?
Yes, the HS3JB has a specified reverse recovery time (trr) of 75 ns maximum, measured under standardized conditions: IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value reflects the diode's ability to transition from conduction to blocking state and is essential for minimizing switching losses and EMI in high-frequency SMPS designs using the HS3JB.
What package type does HS3JB use, and what are its key mechanical attributes?
The HS3JB uses the DO-214AA (SMB) surface-mount package, with matte tin-plated leads compliant with J-STD-002 solderability, UL 94V-0 molding compound, and moisture sensitivity level 1 per J-STD-020. Its low-profile construction (≤1.8 mm height) and cathode band marking ensure compatibility with automated placement and reliable identification during assembly of the HS3JB.
Is HS3JB suitable for use in RoHS-compliant and halogen-free designs?
Yes, HS3JB is fully RoHS compliant and halogen-free per IEC 61249-2-21. Taiwan Semiconductor certifies that the HS3JB meets both requirements, making it suitable for export to EU, China, and other regulated markets. This compliance is documented in the official product specification sheet (Version L2102) and applies to all units shipped as HS3JB.
