Product details
Overview
HS2DA from Taiwan Semiconductor is a 200V, 1.5A surface-mount fast recovery rectifier diode in DO-214AC (SMA) package, featuring 50 ns reverse recovery time, 1.0 V forward voltage at 1.5 A, and 5 µA max reverse leakage at 25°C. It serves as a freewheeling or snubber diode in high-frequency DC/DC converters and switching inverters.
For engineers reviewing the HS2DA datasheet, HS2DA pinout, HS2DA application, or HS2DA equivalent, key selection criteria include its 200V VRRM, fast trr of 50 ns, low-profile SMA package, thermal resistance of 80°C/W, and RoHS/halogen-free compliance for industrial power conversion designs.
Technical Context
The HS2DA employs a glass-passivated single-die PN junction optimized for fast switching in high-frequency power supplies. Its 50 ns reverse recovery time enables efficient operation in 100–500 kHz switching topologies without significant switching loss penalties.
Thermal performance is defined by RθJA = 80°C/W and a maximum junction temperature of +150°C, supporting continuous conduction mode operation under forced-air or moderate PCB copper area conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse voltage before breakdown; sets safe operating limit in 200 V-rated DC bus or clamp circuits. |
| IF | 1.5 A - Continuous average forward current rating; defines steady-state power handling capability with adequate heatsinking. |
| trr | 50 ns - Measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables high-frequency switching with minimal reverse recovery loss. |
| VF | 1.0 V @ IF = 1.5 A, TJ = 25°C - Forward conduction loss directly impacts efficiency and thermal rise in output rectification stages. |
| IR | 5 µA @ VR = 200 V, TJ = 25°C - Low leakage supports stable voltage hold-off in high-impedance snubber or bias networks. |
| RθJA | 80 °C/W - Junction-to-ambient thermal resistance under standard JEDEC test board; guides minimum PCB copper area for thermal management. |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, low-profile plastic case with matte tin-plated leads; polarity indicated by cathode band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck converter); must withstand IFSM = 50 A surge. |
| Cathode | Forward current exit / reverse voltage terminal | Connected to higher-potential rail (e.g., output capacitor positive); marked by visible band; carries full load current and reverse blocking stress. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enhances long-term reliability and moisture resistance per J-STD-020 Level 1 MSL rating. |
| Fast reverse recovery (50 ns) | Reduces switching losses in 100–500 kHz SMPS designs compared to standard recovery diodes. |
| DO-214AC (SMA) package | Enables automated pick-and-place assembly and supports compact board layouts with 0.060 g mass. |
| RoHS and halogen-free compliance | Meets IEC 61249-2-21 and environmental requirements for industrial and consumer end equipment. |
Applications
| DC/DC Converter Output Rectification | Snubber Network Diode |
|---|---|
Use Scenario: Used in secondary-side synchronous or non-synchronous rectification of isolated flyback or forward converters delivering 12–48 V outputs. IC Role / Device Role / Timing Role: Freewheeling diode conducting during MOSFET off-time; handles 1.5 A average current with minimal VF-induced loss. Use Value: 1.0 V VF and 50 ns trr reduce conduction and switching losses, improving overall converter efficiency by ~0.8–1.2% at 250 kHz. | Use Scenario: Placed across switching FETs or transformers in RCD snubber networks to absorb turn-off energy. IC Role / Device Role / Timing Role: Transient clamping diode that conducts only during voltage spikes; requires fast turn-on and low capacitance. Use Value: 50 pF junction capacitance and 50 ns trr ensure rapid response to dV/dt transients without oscillation or delayed conduction. |
| Lighting Ballast Circuit | Freewheeling Diode in Inductive Load Drivers |
Use Scenario: Integrated into electronic ballasts for fluorescent or LED drivers operating from rectified AC mains. IC Role / Device Role / Timing Role: High-voltage rectifier in bridge or voltage-doubler configurations; blocks 200 V reverse peaks from line harmonics. Use Value: 200 V VRRM provides 2× safety margin over 100 V RMS input, while low leakage ensures stable hold-off during zero-crossing intervals. | Use Scenario: Protects MOSFETs driving solenoids, relays, or motors in industrial PLC output modules. IC Role / Device Role / Timing Role: Freewheeling path for inductive kickback; must clamp rapidly to limit drain voltage overshoot. Use Value: 50 ns trr and 50 A IFSM enable reliable suppression of >100 V spikes without secondary breakdown or thermal runaway. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06U (STMicroelectronics) | Same VRRM (200 V), identical IF (1.5 A), but trr = 75 ns and VF = 1.15 V @ 1.5 A. | Slightly higher conduction loss and slower recovery; less optimal in >300 kHz designs. | Acceptable where layout space allows larger thermal margin or frequency is ≤200 kHz. |
| ES1D (ON Semiconductor) | VRRM = 200 V, IF = 1.0 A, trr = 35 ns, VF = 1.05 V - lower current rating, faster recovery. | Not suitable for 1.5 A continuous loads; limited to <1.0 A average applications. | Only viable if load current is reduced or derated; requires PCB rework due to different footprint (DO-214AA). |
Compared with STTH1L06U and ES1D, the HS2DA delivers the best balance of 1.5 A current capability, 50 ns speed, and 1.0 V forward drop in the DO-214AC package-making it preferred for cost-sensitive, space-constrained 200 V SMPS rectification where thermal headroom is limited.

FAQ
What is the maximum junction temperature rating for HS2DA?
The HS2DA has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet Version J2102. This allows continuous operation in ambient temperatures up to +100°C when mounted on a standard FR-4 PCB with 1 in² copper pour, given its RθJA of 80°C/W. Thermal design must ensure the HS2DA junction does not exceed this limit under worst-case load and airflow conditions.
Is HS2DA RoHS and halogen-free compliant?
Yes, the HS2DA is RoHS compliant and halogen-free in accordance with IEC 61249-2-21, as explicitly stated in the "Features" section of the Taiwan Semiconductor HS2AA–HS2MA datasheet (Version J2102). The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated to meet J-STD-002 solderability requirements.
What is the reverse recovery time (trr) specification for HS2DA?
The HS2DA 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, per the Electrical Specifications table in the official datasheet. This value is confirmed across the HS2AA–HS2GA subgroup and is critical for minimizing switching losses in high-frequency DC/DC converters operating above 100 kHz.
Does HS2DA have a specified moisture sensitivity level (MSL)?
Yes, the HS2DA has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, as documented in the "Features" section of the Taiwan Semiconductor datasheet. This means the device can be stored indefinitely at ≤30°C/60% RH and is exempt from bake requirements prior to reflow soldering, simplifying SMT assembly processes.
What is the marking code printed on the HS2DA package?
The HS2DA is marked with "HS2DA" on the device body, as shown in the Marking Diagram on page 5 of the Taiwan Semiconductor HS2AA–HS2MA datasheet (Version J2102). The marking includes the part number prefix "HS2", voltage code "D" (denoting 200 V), and suffix "A", with additional codes for date (YW), factory (F), and green compound (G).
