Product details
Overview
HS1GL from Taiwan Semiconductor is a 1 A, 600 V surface-mount high-efficiency rectifier diode in Sub SMA package, with VF = 1.30 V at 1 A and TJ = 25°C, CJ = 20 pF at 1 MHz / VR = 4.0 V, and trr = 50 ns - used in DC-DC converters and freewheeling paths in switching power supplies.
For engineers reviewing the HS1GL datasheet, HS1GL pinout, HS1GL application, or HS1GL equivalent, key selection criteria include reverse recovery time, junction capacitance at specified test conditions, forward voltage drop under rated current, peak repetitive reverse voltage rating, and thermal resistance for board-level thermal design.
Technical Context
The HS1GL is a single-die, glass-passivated silicon PN junction rectifier optimized for high-frequency switching applications. Its 50 ns reverse recovery time and 20 pF junction capacitance at 1 MHz / 4.0 V bias enable low switching loss in SMPS flyback and boost topologies.
Rated for 600 V repetitive peak reverse voltage (VRRM) and 1 A average forward current (IF), it operates across –55°C to +150°C junction temperature range with 100°C/W junction-to-ambient thermal resistance - supporting compact, convection-cooled designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse voltage the device blocks without breakdown; defines usable input voltage range in offline or high-voltage DC-DC stages |
| IF | 1 A - continuous average forward current rating; sets maximum steady-state output current capability in rectification path |
| VF @ 1A, 25°C | 1.30 V - forward voltage drop determining conduction loss and thermal load at full rated current |
| trr | 50 ns - reverse recovery time defining switching speed limit and associated turn-off losses in hard-switched converters |
| CJ @ 1MHz, VR=4V | 20 pF - junction capacitance affecting high-frequency impedance and EMI generation during switching transitions |
| RθJA | 100 °C/W - thermal resistance from junction to ambient; used to calculate temperature rise on standard FR-4 PCB with no heatsink |
Pinout & Package
Package: Sub SMA - low-profile, surface-mount plastic package with matte tin-plated leads, J-STD-002 solderable, UL 94V-0 molding compound, cathode indicated by band.

| Low profile Sub SMA package | Enables ultra-thin power supply designs and compatibility with automated SMT placement equipment |
| Junction capacitance = 20 pF @ 1 MHz / 4 V | Minimizes capacitive coupling and high-frequency ringing in fast-switching topologies like QR flyback |
| Reverse recovery time = 50 ns | Reduces turn-off switching loss compared to general-purpose rectifiers (>100 ns), improving efficiency above 100 kHz |
Applications
| AC-DC Adapter Output Rectification | DC-DC Boost Converter Freewheel Diode |
|---|---|
Use Scenario: Secondary-side rectification in 5–24 W universal-input AC-DC adapters using QR flyback controllers. IC Role / Device Role / Timing Role: Unidirectional current valve converting transformer AC output to regulated DC; conducts only during transformer demagnetization phase. Use Value: 50 ns trr and 1.30 V VF minimize conduction + switching losses, enabling >88% efficiency at full load without active synchronous rectification. | Use Scenario: Freewheel path in non-isolated 12 V → 24 V boost converter for industrial sensor power rails. IC Role / Device Role / Timing Role: Provides current continuity path during high-side switch off-time; clamps inductive kickback voltage. Use Value: 600 V VRRM headroom accommodates transient overshoots up to 40 V input, while 20 pF CJ reduces high-frequency noise injection into control loop. |
| Switched-Mode Inverter Auxiliary Supply | Industrial PLC Input Protection Rectifier |
Use Scenario: Auxiliary 15 V supply derived from main DC bus in 3-phase motor drive inverters. IC Role / Device Role / Timing Role: High-voltage rectifier feeding buck regulator input; handles 400–650 V DC link ripple. Use Value: 100°C/W RθJA allows operation at 75°C ambient without forced air, and 150°C TJ max supports derating over lifetime. | Use Scenario: Input-stage rectification and polarity protection for 24 V DC digital inputs in programmable logic controllers. IC Role / Device Role / Timing Role: Prevents damage from reverse-connected field wiring; conducts only during valid positive half-cycles. Use Value: 1 A IF rating sustains surge currents from inductive field devices, while 5 µA IR at 25°C ensures minimal leakage-induced false triggering. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06 | Same VRRM (600 V), IF (1 A), but VF = 1.15 V typ @ 1 A; trr = 45 ns; DO-214AC package | Lower VF and faster trr improve light-load efficiency; larger DO-214AC footprint requires PCB redesign | Select when higher efficiency justifies layout change and thermal margin permits larger package |
| MBR160L | Lower VRRM (60 V), Schottky structure, VF = 0.52 V typ @ 1 A, trr not applicable; same Sub SMA package | Not suitable for >100 V applications; eliminates reverse recovery loss but limited to low-voltage DC-DC outputs | Select only for ≤60 V output rectification where ultra-low VF outweighs voltage limitation |
Compared with STTH1R06 and MBR160L, the HS1GL offers balanced performance in 600 V systems with Sub SMA footprint compatibility, making it optimal for cost-sensitive, space-constrained 1 A rectification where moderate VF and proven 50 ns trr meet target efficiency specs without layout revision.

FAQ
What is the maximum junction temperature rating for HS1GL?
The HS1GL has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet. This rating enables reliable operation in thermally demanding environments such as enclosed industrial power supplies. Derating curves confirm usable current capacity down to –55°C ambient, and the device must be mounted on PCB copper area sufficient to maintain TJ ≤ 150°C under worst-case power dissipation. Thermal design should reference RθJA = 100°C/W for standard FR-4 layouts.
Does HS1GL have a specified reverse recovery time, and under what test conditions?
Yes, HS1GL has a specified reverse recovery time (trr) of 50 ns maximum, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the official Taiwan Semiconductor datasheet. This parameter is critical for evaluating switching loss in high-frequency converters. The test circuit and waveform definitions are provided in Figure 6 of the HS1AL–HS1ML datasheet. trr remains stable across –55°C to +125°C operating range, supporting consistent timing behavior in variable-temperature applications.
What is the junction capacitance value of HS1GL, and at what frequency and bias is it specified?
The junction capacitance (CJ) of HS1GL is 20 pF, specified at 1 MHz and VR = 4.0 V reverse bias, as confirmed in the Electrical Specifications table of the Taiwan Semiconductor datasheet. This value is measured using small-signal AC conditions (Vsig = 50 mVp-p) and directly impacts high-frequency impedance and EMI characteristics in switching nodes. CJ decreases with increasing reverse voltage - e.g., ~15 pF at VR = 20 V - and must be modeled accordingly in SPICE simulations.
Is HS1GL RoHS compliant and halogen-free?
Yes, HS1GL is RoHS compliant and halogen-free according to IEC 61249-2-21, as explicitly stated in the Features section of the official Taiwan Semiconductor datasheet. The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated per J-STD-002. Moisture sensitivity level is rated at Level 1 (unlimited floor life at ≤30°C/85% RH), eliminating bake requirements prior to reflow. Full compliance documentation is available upon request from Aetrix Electronics.
What marking code appears on the HS1GL device body?
The HS1GL device is marked with "HGL" on its package body, as defined in the Absolute Maximum Ratings table and Marking Diagram section of the Taiwan Semiconductor datasheet. This three-character code uniquely identifies the 600 V variant within the HS1xL series (HS1AL = 50 V, HS1BL = 100 V, ..., HS1GL = 600 V). The cathode is indicated by a visible band adjacent to the marking, and the compound is green (G), per standard TSC marking convention.
