Product details
Overview
HS2DA-T from Taiwan Semiconductor is a 2A, 200V glass-passivated surface-mount rectifier in DO-214AC (SMA) package, optimized for high-efficiency DC-DC converters and switching-mode inverters with low forward voltage (0.91 V at 2A/25°C) and low reverse leakage (≤5 µA at 25°C). It operates up to 150°C junction temperature and supports surge currents up to 50 A (8.3 ms).
For engineers reviewing the HS2DA-T datasheet, HS2DA-T pinout, HS2DA-T application, or HS2DA-T equivalent, key selection criteria include repetitive peak reverse voltage (200 V), forward current rating (2 A), thermal resistance (RθJL = 14 °C/W), reverse recovery time (≤50 ns), and DO-214AC mechanical compatibility in space-constrained power designs.
Technical Context
The HS2DA-T is a single-die, silicon planar epitaxial fast recovery rectifier with glass-passivated junction for enhanced reliability and moisture resistance (J-STD-020 Level 1). Its low trr (≤50 ns) and low Qrr support high-frequency switching topologies.
Thermal performance is characterized on a 5 mm × 5 mm copper pad PCB: RθJA = 86 °C/W, RθJC = 23 °C/W, enabling stable operation under continuous 2 A conduction at ambient temperatures up to +85°C with appropriate board layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse blocking voltage; defines safe operating range in flyback/freewheeling paths |
| IF | 2 A - Continuous average forward current; determines steady-state power handling in DC-DC output stages |
| IFSM | 50 A (8.3 ms) - Non-repetitive surge capability; supports inrush and transient overload tolerance |
| VF | 0.91 V @ 2A/25°C - Low conduction loss; reduces power dissipation and improves efficiency in high-duty-cycle applications |
| trr | ≤50 ns - Fast reverse recovery; minimizes switching losses and EMI in >100 kHz SMPS designs |
| RθJL | 14 °C/W - Junction-to-lead thermal resistance; enables direct heat transfer to PCB copper for passive thermal management |
| IR | ≤5 µA @ 25°C - Low reverse leakage; critical for maintaining regulation and reducing standby power in offline converters |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, cathode indicated by band. Matte tin-plated leads, UL 94V-0 molding compound, JESD201 Class 1 whisker compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry | Connected to lower-potential node (e.g., switch node in buck converter); requires adequate copper pour for thermal relief |
| Cathode | Forward current exit / reverse blocking terminal | Connected to output rail or ground return; polarity band must align with PCB silkscreen for automated placement |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable long-term reverse leakage performance and humidity resistance per J-STD-020 Level 1 |
| Low VF (0.91 V @ 2A) | Reduces conduction loss by ~15% vs. standard 2A rectifiers, directly improving converter efficiency at full load |
| Fast trr ≤50 ns | Supports clean turn-off in synchronous rectification and high-frequency (>200 kHz) topologies without snubber circuits |
| DO-214AC (SMA) package | Standardized footprint compatible with automated SMT lines; 0.060 g weight aids reflow yield and board-level shock resistance |
Applications
| DC-DC Converter Output Rectification | Switching Mode Inverter Freewheeling |
|---|---|
Use Scenario: Secondary-side rectification in isolated 24 V–48 V DC-DC modules delivering up to 48 W. IC Role / Device Role / Timing Role: Unidirectional current path converting transformer AC output to regulated DC; conducts during positive half-cycle only. Use Value: 0.91 V forward drop at 2 A lowers conduction loss by 0.18 W vs. 1.09 V alternatives, improving full-load efficiency by 0.8–1.2%. | Use Scenario: Freewheeling path across IGBTs in 3-phase motor drive inverters operating at 10–20 kHz PWM frequency. IC Role / Device Role / Timing Role: Provides low-loss current recirculation path during IGBT off-time; clamps inductive kickback. Use Value: ≤50 ns trr prevents reverse recovery tail current, reducing switching loss and preventing shoot-through risk in hard-switched bridges. |
| Offline AC-DC Auxiliary Supply | Industrial Power Factor Correction (PFC) Clamp |
Use Scenario: Bias supply rectification in 10–25 W auxiliary rails of industrial AC-DC adapters. IC Role / Device Role / Timing Role: Converts rectified AC line voltage (after bridge) to stable DC for control ICs and gate drivers. Use Value: 200 V VRRM safely withstands 170 Vpk (120 VAC) plus margin; ≤5 µA IR ensures minimal standby power draw. | Use Scenario: Snubber clamp diode in boost PFC stages where voltage spikes exceed 150 V during transients. IC Role / Device Role / Timing Role: Absorbs inductive energy from boost inductor during MOSFET turn-off, limiting voltage overshoot. Use Value: 50 A IFSM rating handles repeated 30–50 A spike events; glass passivation ensures reliability under high dv/dt stress. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R02U | 2 A, 200 V ultrafast rectifier; trr = 35 ns, VF = 0.95 V @ 2A - slightly faster but higher forward drop | Better suited for >300 kHz resonant converters where trr dominates loss | Prefer HS2DA-T when thermal resistance (RθJL = 14 °C/W) and cost are prioritized over marginal trr reduction |
| MBR220LSFT1G | 2 A, 200 V Schottky; VF = 0.52 V @ 2A, but VRRM derated above 125°C and IR rises sharply with temperature | Lower conduction loss at room temp, but unsuitable for high-temp or high-VR hold-off requirements | Choose HS2DA-T for designs requiring guaranteed 200 V blocking at 150°C junction or <5 µA leakage at 125°C |
Compared with STTH2R02U and MBR220LSFT1G, the HS2DA-T delivers optimal balance of low thermal resistance, stable high-temperature leakage, and cost-effective fast-recovery performance for industrial DC-DC and inverter freewheeling-without Schottky limitations or premium ultrafast pricing.

FAQ
What is the maximum junction temperature rating for the HS2DA-T?
The HS2DA-T has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet Version D2111. This allows reliable operation in enclosed industrial environments where ambient temperatures reach +85°C, provided PCB thermal design maintains junction-to-lead resistance at 14 °C/W. The HS2DA-T must not be operated beyond this limit to ensure long-term reliability and parameter stability.
Does the HS2DA-T have a specified reverse recovery time (trr)?
Yes, the HS2DA-T has a maximum reverse recovery time (trr) of 50 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and IRR = 0.25 A, as documented in the Electrical Specifications table of the Taiwan Semiconductor HS2DA-T–HS2MA-T datasheet (Version D2111). This value is confirmed for the exact HS2DA-T variant and supports high-frequency switching in DC-DC and inverter applications.
What package type does the HS2DA-T use, and is it RoHS compliant?
The HS2DA-T uses the DO-214AC (SMA) surface-mount package with matte tin-plated leads and UL 94V-0 compliant molding compound. It is fully RoHS compliant and halogen-free per IEC 61249-2-21, as stated in the Features section of the official Taiwan Semiconductor datasheet. The HS2DA-T also meets J-STD-020 moisture sensitivity level 1 and JESD201 Class 1 whisker resistance requirements.
What is the forward voltage (VF) of the HS2DA-T at 2 A and 25°C?
The forward voltage (VF) of the HS2DA-T is 0.91 V at 2 A and 25°C, with a maximum of 1.00 V under the same conditions, per the Electrical Specifications table in the Taiwan Semiconductor datasheet (Version D2111). This value is measured using a pulse test with 0.3 ms pulse width and is representative of typical conduction loss in continuous-duty power conversion stages.
How does the HS2DA-T compare to higher-voltage variants like HS2MA-T in terms of forward characteristics?
The HS2DA-T maintains identical forward current (2 A), forward voltage (0.91 V @ 2A/25°C), and thermal parameters (RθJL = 14 °C/W) as other HS2x-T family members; only VRRM differs (200 V for HS2DA-T vs. 1000 V for HS2MA-T). All variants share the same DO-214AC package, marking format (HS2DA), and fast-recovery architecture-making HS2DA-T the lowest-voltage, highest-efficiency option in the series for 200 V-class applications.
