Product details
Overview
HS2GFL from Taiwan Semiconductor is a 2 A, 400 V glass-passivated surface-mount fast recovery rectifier in SOD-123FL package, featuring 1.06 V forward voltage at 2 A / 25°C, 50 ns reverse recovery time, and 16 pF junction capacitance - deployed in DC-DC converters and switching-mode inverters.
For engineers reviewing the HS2GFL datasheet, HS2GFL pinout, HS2GFL application, or HS2GFL equivalent, key selection criteria include peak reverse voltage rating (400 V), thermal resistance (RθJL = 81 °C/W), low leakage (<5 µA @ 25°C), and SOD-123FL footprint compatibility with automated placement.
Technical Context
This device is a single-die, unidirectional silicon PN junction rectifier optimized for high-efficiency switching power supplies. Its fast recovery (trr ≤ 50 ns) and low Qrr reduce switching losses in high-frequency topologies.
The SOD-123FL package enables compact board layout with matte tin-plated leads compliant to J-STD-002 solderability and JESD 201 Class 1 whisker resistance. Thermal performance is characterized on a 5 mm × 5 mm Cu pad test board.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum repetitive reverse blocking voltage; defines usable input voltage range in off-line or boost-stage rectification. |
| IF | 2 A - Continuous average forward current; supports sustained conduction in 20–500 kHz SMPS outputs. |
| trr | 50 ns - Reverse recovery time at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables efficient operation up to ~1 MHz switching. |
| VF @ 2 A, 25°C | 1.06 V (typ), 1.30 V (max) - Directly impacts conduction loss and thermal rise in high-current paths. |
| CJ @ 1 MHz, 4 V | 16 pF - Junction capacitance affects high-frequency noise coupling and snubber design in flyback/LLC circuits. |
| RθJL | 81 °C/W - Junction-to-lead thermal resistance; determines heat transfer efficiency to PCB copper when lead-soldered. |
| IR @ VRRM, 25°C | ≤5 µA - Low reverse leakage preserves efficiency in high-impedance bias networks and standby modes. |
Pinout & Package
Package: SOD-123FL - Surface-mount plastic case with cathode band marking, UL 94V-0 molding compound, 0.016 g mass, and polarity indicated by molded band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of rectified path; requires adequate copper pour for thermal dissipation. |
| Cathode | Forward current exit / reverse-blocking terminal | Marked by visible band; ties to output rail or switch node; critical for EMI filtering layout. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable long-term reliability under humidity and thermal cycling; eliminates need for conformal coating in industrial environments. |
| Moisture sensitivity level 1 | Zero bake requirement before reflow; compatible with standard SMT assembly lines without dry-pack handling. |
| RoHS & halogen-free compliance | Meets IEC 61249-2-21 and EU RoHS directives; supports eco-design certification for end equipment. |
| Fast recovery (50 ns) | Reduces switching loss and diode-induced ringing in synchronous rectifier auxiliary paths and freewheeling legs. |
Applications
| DC-DC Converter Output Rectification | Switching Inverter Freewheeling |
|---|---|
Use Scenario: Secondary-side rectification in isolated 24–48 V output DC-DC converters operating at 100–300 kHz. IC Role / Device Role / Timing Role: Unidirectional current valve converting transformer AC to regulated DC; handles continuous 2 A load with minimal conduction loss. Use Value: 1.06 V VF at 2 A reduces power loss to <2.1 W, easing thermal management versus higher-VF alternatives. | Use Scenario: Freewheeling path in half-bridge motor drive inverters for HVAC blowers and pump controllers. IC Role / Device Role / Timing Role: Provides low-loss return path during high-side switch off-time; clamps inductive kickback with 400 V VRRM. Use Value: 50 ns trr minimizes reverse recovery charge (Qrr), suppressing voltage spikes and MOSFET stress. |
| AC-DC Adapter Input Bridge | Industrial Power Supply Snubber Diode |
Use Scenario: Discrete bridge leg in universal-input (85–265 VAC) offline adapters rated ≤30 W. IC Role / Device Role / Timing Role: One quadrant of full-wave rectification; withstands 400 V PIV with low leakage at elevated ambient temperatures. Use Value: ≤5 µA IR at 25°C ensures minimal no-load power draw and stable hold-up time during brownouts. | Use Scenario: RC snubber clamp diode across IGBTs in 3-phase industrial VFDs operating at 10–20 kHz. IC Role / Device Role / Timing Role: Absorbs turn-off energy spike; operates intermittently but demands robust surge capability (IFSM = 40 A). Use Value: 40 A IFSM (8.3 ms) provides margin against transient overcurrents without derating. |
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 |
|---|---|---|---|
| ON Semiconductor MUR240 | Same 400 V VRRM, 2 A IF, but TO-220AC package; trr = 50 ns, VF = 1.25 V @ 2 A - higher conduction loss. | Requires through-hole mounting and heatsinking; unsuitable for space-constrained SMT designs. | Select when higher surge rating (IFSM = 65 A) or legacy through-hole compatibility is required. |
| Vishay VSKY240 | SOD-123FL package, same 400 V/2 A rating, but trr = 35 ns and VF = 0.98 V @ 2 A - faster and lower loss. | Superior high-frequency efficiency in >500 kHz resonant converters; tighter VF tolerance. | Select when minimizing switching loss or improving light-load efficiency is critical. |
Compared with MUR240 and VSKY240, HS2GFL delivers optimal balance of SMT compatibility, thermal resistance (81 °C/W), and cost in mid-frequency SMPS where 50 ns recovery suffices and lead-free reflow is mandatory.

FAQ
What is the maximum junction temperature rating for HS2GFL?
The HS2GFL has a maximum junction temperature (TJ) of +150°C, validated per absolute maximum ratings in the official datasheet. This allows reliable operation in enclosed industrial enclosures or near heat-generating components. Derating curves confirm 2 A average current is sustainable up to 100°C ambient when mounted on a 5 mm × 5 mm Cu pad. Always verify thermal design using RθJL = 81 °C/W and actual board copper area for HS2GFL.
Does HS2GFL support lead-free reflow soldering?
Yes, HS2GFL supports lead-free reflow soldering per J-STD-002 requirements. Its matte tin-plated leads are qualified for peak reflow temperatures up to 260°C, and its moisture sensitivity level is rated at Level 1 per J-STD-020 - meaning no baking or dry-pack handling is required prior to assembly. This makes HS2GFL fully compatible with standard RoHS-compliant SMT lines.
What is the reverse recovery time (trr) specification for HS2GFL?
The HS2GFL has a reverse recovery time (trr) of ≤50 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is confirmed in the Electrical Specifications table of the B2103 datasheet revision. The 50 ns trr enables efficient use in 100–300 kHz switching converters without excessive switching loss or voltage overshoot.
Can HS2GFL be used as a direct replacement for HS2DFL in existing designs?
No, HS2GFL is not a direct replacement for HS2DFL due to differing VRRM ratings: HS2DFL is rated for 200 V, while HS2GFL is rated for 400 V. Although both share identical package (SOD-123FL), forward characteristics, and thermal specs, substituting HS2GFL into a 200 V design may result in unnecessary cost and margin overhead. Use HS2GFL only where 400 V blocking is required - always validate voltage stress margins in the target circuit for HS2GFL.
What is the junction capacitance (CJ) of HS2GFL and how does it affect circuit performance?
The HS2GFL exhibits a typical junction capacitance (CJ) of 16 pF at 1 MHz and 4 V reverse bias. This value influences high-frequency noise coupling and snubber network tuning - particularly in flyback transformers and LLC resonant tanks. Lower CJ than HS2DFL (21 pF) improves EMI behavior at >1 MHz, while remaining higher than HS2JFL (10 pF), making HS2GFL well-suited for mid-frequency SMPS where capacitive loading must be balanced against recovery speed.
