Product details
Overview
HS1JL from Taiwan Semiconductor is a 1 A, 600 V repetitive peak reverse voltage surface-mount silicon rectifier diode in Sub SMA package, featuring 1.70 V max forward voltage at 1 A and 75 ns reverse recovery time, used for freewheeling and switching-mode power supply output rectification.
For engineers reviewing the HS1JL datasheet, HS1JL pinout, HS1JL application, or HS1JL equivalent, key selection criteria include its 600 V VRRM rating, 1.70 V VF at 1 A, 75 ns trr, Sub SMA low-profile package compatibility with automated placement, and moisture sensitivity level 1 compliance.
Technical Context
The HS1JL is a single-die, glass-passivated junction silicon rectifier optimized for high-efficiency DC/DC conversion. Its 600 V VRRM and 30 A IFSM support robust surge handling in switching inverters and flyback topologies.
Thermal resistance RθJA is 100 °C/W, and junction capacitance is 15 pF at 1 MHz and 4.0 V reverse bias - enabling stable high-frequency operation in compact power stages where parasitic capacitance must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports input/output isolation in 48 V–400 V bus systems with safety margin |
| IF | 1 A continuous - suitable for medium-power auxiliary rails and low-current secondary-side rectification |
| VF (max) | 1.70 V at 1 A, 25°C - determines conduction loss and thermal rise in high-duty-cycle operation |
| trr | 75 ns - enables use in 100–500 kHz SMPS without excessive switching loss or EMI |
| CJ | 15 pF at 1 MHz, VR = 4.0 V - limits capacitive coupling and improves noise immunity in fast-switching nodes |
| RθJA | 100 °C/W - defines thermal derating slope; requires ≤ 100 mm² copper pad for full 1 A rating at TA = 70°C |
| MSL | Level 1 per J-STD-020 - allows unlimited floor life and standard reflow without baking |
Pinout & Package
Package: Sub SMA - low-profile surface-mount package with matte tin-plated leads, UL 94V-0 molding compound, cathode band polarity marking, and 0.019 g mass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal | Connected to lower-potential node (e.g., transformer secondary center-tap or switch node return) |
| Cathode | Current exit terminal | Marked by band; connects to output rail or filter capacitor positive; carries full load current |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable leakage performance across temperature and humidity; IR ≤ 5 µA at 25°C, ≤ 150 µA at 125°C |
| Low profile Sub SMA | Height ≤ 2.3 mm - fits under height-constrained shields and enables dense PCB layouts |
| Moisture sensitivity level 1 | No dry-pack requirement or bake preconditioning needed before SMT assembly |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for green manufacturing |
Applications
| DC/DC Converter Output Rectification | Switching Inverter Freewheeling |
|---|---|
Use Scenario: Secondary-side rectification in isolated 24–48 V input DC/DC converters delivering up to 12 V/1 A output. IC Role / Device Role / Timing Role: Unidirectional current path enabling efficient energy transfer from transformer to output capacitor. Use Value: 1.70 V VF minimizes conduction loss; 75 ns trr reduces switching loss at 250 kHz operation. | Use Scenario: Freewheeling path across inductive loads in half-bridge motor drive inverters operating at 10–100 kHz. IC Role / Device Role / Timing Role: Provides controlled current recirculation during MOSFET off-time to prevent voltage spikes. Use Value: 600 V VRRM withstands reflected inductive kick; 30 A IFSM handles transient surge currents. |
| AC-DC Adapter Secondary Side | Industrial Power Supply Auxiliary Rail |
Use Scenario: Output rectification in universal-input (90–264 VAC) offline adapters delivering 5–12 V at ≤1 A. IC Role / Device Role / Timing Role: Converts transformer secondary AC to regulated DC; placed after high-frequency transformer. Use Value: Sub SMA package allows automated placement; MSL Level 1 simplifies manufacturing flow. | Use Scenario: +12 V or +15 V auxiliary bias rail generation in industrial PLC power modules. IC Role / Device Role / Timing Role: Supplies isolated gate drivers or op-amp bias; operates continuously under partial load. Use Value: 150 °C max junction temperature ensures reliability in sealed enclosures with limited airflow. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06 | Same 1 A / 600 V rating; VF = 1.7 V typ (vs. 1.70 V max); trr = 60 ns (vs. 75 ns max) | Slightly faster recovery but tighter VF distribution; requires verification of Sub SMA footprint compatibility | Preferred where <65 ns trr is critical; confirm cathode band orientation matches HS1JL layout |
| MBR160 | Lower 60 V VRRM; Schottky construction; VF = 0.75 V typ; no reverse recovery (trr = N/A) | Only suitable for ≤42 V DC systems; cannot replace HS1JL in 600 V applications | Select only for low-voltage, ultra-low-loss requirements; not a voltage-compatible alternative |
Compared with STTH1R06 and MBR160, the HS1JL provides verified 600 V blocking capability with industry-standard Sub SMA packaging and MSL Level 1 handling - making it optimal for cost-sensitive, medium-voltage industrial and adapter designs where robustness and manufacturability are prioritized over marginal trr reduction.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of the HS1JL?
The HS1JL has a maximum repetitive peak reverse voltage (VRRM) of 600 V, as specified in the absolute maximum ratings table of the official Taiwan Semiconductor datasheet (Version C2103). This rating defines the highest reverse voltage the HS1JL can block repeatedly without breakdown under normal operating conditions, making it suitable for 400 V DC bus applications with safety margin.
What is the forward voltage (VF) specification for the HS1JL at rated current?
The HS1JL has a maximum forward voltage (VF) of 1.70 V at 1 A forward current and 25°C junction temperature. This value is measured under pulsed conditions (PW = 0.3 ms) and represents the worst-case conduction drop used for thermal and efficiency calculations in designs using the HS1JL.
Does the HS1JL have a defined reverse recovery time (trr), and what is its value?
Yes, the HS1JL has a specified reverse recovery time (trr) of 75 ns maximum, tested at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter is critical for high-frequency switching applications and confirms the HS1JL's suitability for use in converters operating up to 500 kHz without excessive switching loss.
What package type does the HS1JL use, and what are its key mechanical attributes?
The HS1JL uses the Sub SMA package: a low-profile surface-mount outline with matte tin-plated leads, UL 94V-0 molding compound, cathode band polarity marking, and a mass of approximately 0.019 g. It complies with J-STD-002 for solderability and JESD 201 Class 1A for whisker resistance.
Is the HS1JL compliant with RoHS and halogen-free standards?
Yes, the HS1JL is RoHS compliant per EU Directive 2011/65/EU and halogen-free per IEC 61249-2-21. These compliance statements are explicitly confirmed in the "Features" section of the Taiwan Semiconductor HS1AL–HS1ML datasheet (Version C2103), and apply directly to the HS1JL variant.
