Product details
Overview
HS1J-K from Taiwan Semiconductor is a 1 A, 600 V high-efficiency surface-mount silicon rectifier diode in DO-214AC (SMA) package, featuring glass-passivated junction, low forward voltage drop (1.7 V max at 1 A), fast reverse recovery time (75 ns), and rated for junction temperatures up to 150°C. It is used in DC-DC converters and switching-mode inverters requiring reliable freewheeling and high thermal efficiency.
For engineers reviewing the HS1J-K datasheet, HS1J-K pinout, HS1J-K application, or HS1J-K equivalent, key selection criteria include its 600 V repetitive peak reverse voltage, 30 A surge rating, 15 pF junction capacitance, moisture sensitivity level 1 compliance, and RoHS/halogen-free qualification - all critical for power supply and industrial converter design.
Technical Context
The HS1J-K is a single-die, unidirectional silicon rectifier optimized for high-frequency switching applications. Its glass-passivated junction ensures stable performance under thermal cycling, while the DO-214AC (SMA) package supports automated placement and meets UL 94V-0 flammability standards.
Electrical behavior is defined by a maximum forward voltage of 1.7 V at 1 A and 25°C, reverse leakage of ≤5 µA at 25°C and rated VR, and a reverse recovery time of 75 ns under standardized test conditions (IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A), confirming suitability for medium-voltage SMPS topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse voltage the device blocks reliably in circuit |
| IF | 1 A continuous - average forward current capability at 70°C ambient with standard PCB layout |
| IFSM | 30 A - peak non-repetitive surge current tolerance for transient protection during startup or fault |
| VF (max) | 1.7 V at 1 A, 25°C - directly impacts conduction loss and thermal rise in power stage |
| trr | 75 ns - determines switching losses and EMI profile in hard-switched converters |
| CJ | 15 pF at 1 MHz, 4 V - affects high-frequency noise coupling and snubber design |
| TJ max | 150°C - sets upper thermal limit for reliability margin in enclosed or high-ambient environments |

Applications
| DC-DC Converter | Switching Inverter |
|---|---|
Use Scenario: Isolated flyback or forward converter output rectification in telecom power supplies. IC Role / Device Role / Timing Role: Output rectifier handling 1 A continuous current at 600 V blocking requirement. Use Value: Low VF minimizes conduction loss; 75 ns trr reduces switching loss and improves efficiency above 100 kHz. | Use Scenario: Freewheeling path in half-bridge motor drive inverters for HVAC or industrial pumps. IC Role / Device Role / Timing Role: Unidirectional current clamp protecting IGBTs during inductive load commutation. Use Value: 30 A IFSM withstands motor startup surges; 150°C TJ rating supports operation near heatsink-limited zones. |
| Freewheeling Diode | SMPS Secondary Rectifier |
Use Scenario: Inductor energy recirculation in buck-derived regulators powering FPGA or ASIC core rails. IC Role / Device Role / Timing Role: Fast-recovery path for stored inductor current when main switch turns off. Use Value: 75 ns trr limits voltage overshoot and ringing; DO-214AC footprint allows compact layout near power inductors. | Use Scenario: Secondary-side rectification in offline AC-DC adapters rated up to 15 W. IC Role / Device Role / Timing Role: High-voltage secondary rectifier operating at 600 V reverse bias with 1 A load. Use Value: 600 V VRRM provides safety margin over reflected 400–450 V peaks; 1.7 V VF balances efficiency vs. thermal derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06U | 600 V, 1 A, 75 ns trr, but TO-277 package (not SMA); VF = 1.7 V typical | Requires different footprint and thermal pad layout; higher RθJA due to package | Choose if board-level thermal management favors TO-277 or if STMicro ecosystem alignment is required |
| ES1J | 600 V, 1 A, 75 ns trr, DO-214AC (SMA) package; VF = 1.7 V max, but not halogen-free certified | Same footprint and electrical specs, but lacks IEC 61249-2-21 halogen-free compliance | Choose only where halogen-free mandate does not apply; otherwise HS1J-K maintains full compliance |
Compared with STTH1R06U and ES1J, the HS1J-K uniquely combines DO-214AC (SMA) compatibility, halogen-free certification, and moisture sensitivity level 1 - enabling drop-in replacement in RoHS-compliant, high-volume SMT lines without process requalification.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for HS1J-K?
The HS1J-K has a VRRM rating of 600 V, meaning it can reliably block up to 600 volts of reverse voltage in repetitive operation without breakdown. This value is confirmed in the Absolute Maximum Ratings table of the official TSC datasheet (Version F2111) and defines the upper limit for safe operation in rectifier or freewheeling configurations where reverse bias occurs.
Does HS1J-K meet RoHS and halogen-free requirements?
Yes, HS1J-K is RoHS compliant and halogen-free per IEC 61249-2-21. These qualifications are explicitly stated in the FEATURES section of the TSC datasheet and verified through material declarations. The halogen-free status applies to the molding compound and plating, making HS1J-K suitable for environmentally regulated end equipment such as industrial power supplies and consumer adapters.
What is the forward voltage drop (VF) specification for HS1J-K at rated current?
The HS1J-K has a maximum forward voltage drop of 1.7 V at 1 A forward current and 25°C junction temperature. This value is specified in the Electrical Specifications table under "Forward voltage(1)" and reflects worst-case conduction loss under standard test conditions (pulse width = 0.3 ms). Actual VF in circuit will vary with temperature and current, but remains bounded by this limit for thermal design.
Is HS1J-K suitable for automated SMT assembly?
Yes, HS1J-K is designed for automated placement, as confirmed by its DO-214AC (SMA) package, matte tin-plated leads compliant with J-STD-002, and moisture sensitivity level 1 per J-STD-020. This means no pre-baking is required before reflow, and the device supports high-yield pick-and-place processes in volume manufacturing environments without special handling.
What is the junction-to-ambient thermal resistance (RθJA) of HS1J-K?
The HS1J-K has a typical junction-to-ambient thermal resistance of 70°C/W under standard JEDEC test conditions (single device on 1-inch² copper pad). This value is listed in the THERMAL PERFORMANCE section and serves as a baseline for estimating temperature rise in PCB layouts; actual RθJA will improve with added copper area or thermal vias, but 70°C/W must be used for conservative thermal margining.
