Product details
Overview
HS2D-T from Taiwan Semiconductor is a 2 A, 200 V glass-passivated surface-mount rectifier diode in DO-214AA (SMB) package, featuring 50 A surge current rating, 150 °C maximum junction temperature, and low 0.91 V forward voltage at 2 A and 25 °C - used in DC-DC converters and freewheeling paths.
For engineers reviewing the HS2D-T datasheet, HS2D-T pinout, HS2D-T application, or HS2D-T equivalent, key selection criteria include repetitive peak reverse voltage (200 V), forward voltage at rated current, thermal resistance (RθJL = 20 °C/W), reverse leakage (<5 µA at 25 °C), and SMB package compatibility with automated placement.
Technical Context
This is a single-die, standard recovery silicon rectifier optimized for switching-mode power supplies. It uses glass passivation for stable junction performance and meets J-STD-020 moisture sensitivity level 1.
Thermal design relies on its 20 °C/W junction-to-lead resistance when mounted on a 10 mm × 10 mm copper pad; electrical behavior is characterized by 50 ns typical reverse recovery time and 30 pF junction capacitance at 1 MHz / 4 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward current (IF) | 2 A continuous - supports medium-power DC-DC output stages |
| Repetitive peak reverse voltage (VRRM) | 200 V - defines maximum blocking capability in flyback or buck-boost topologies |
| Surge peak forward current (IFSM) | 50 A (8.3 ms) - withstands transient inrush during startup or fault conditions |
| Max junction temperature (TJ MAX) | 150 °C - enables operation in thermally constrained industrial environments |
| Forward voltage (VF) | 0.91 V @ 2 A, 25 °C - directly impacts conduction loss and thermal budget |
| Reverse recovery time (trr) | 50 ns typical - limits switching losses in high-frequency SMPS designs |
| Junction capacitance (CJ) | 30 pF @ 1 MHz, 4 V - affects high-frequency noise coupling and snubber design |

Applications
| DC-DC Converter Output Rectification | Switching Mode Inverter Freewheeling |
|---|---|
Use Scenario: Secondary-side rectification in isolated 20–50 W offline flyback converters. IC Role / Device Role / Timing Role: Unidirectional current path converting transformer AC output to regulated DC. Use Value: 0.91 V VF at 2 A reduces conduction loss vs. higher-VF alternatives, improving efficiency by ~0.5% at full load. | Use Scenario: Freewheeling path across inductive loads in half-bridge motor inverters. IC Role / Device Role / Timing Role: Provides safe current recirculation during MOSFET off-time to prevent voltage spikes. Use Value: 50 ns trr ensures clean commutation below 200 kHz switching, avoiding shoot-through risk. |

Use Value: 150 °C TJ max and -55 °C to +150 °C storage range support operation in harsh cabinet environments. | Use Scenario: 12 V to 5 V/3.3 V auxiliary supply in automotive body control modules. IC Role / Device Role / Timing Role: Secondary rectifier in compact, thermally limited isolated DC-DC converters. Use Value: DO-214AA (SMB) footprint allows dense layout; RθJL = 20 °C/W enables direct PCB heat sinking without heatsink. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R02DJF | 2 A, 200 V, TO-277 package; VF = 0.95 V @ 2 A, trr = 35 ns | Lower trr but larger footprint and no tape-and-reel option in standard distribution | Prefer when faster recovery is critical and board space permits TO-277 mounting |
| SB220-E3/52 | 2 A, 200 V, DO-214AA; VF = 0.93 V @ 2 A, trr = 50 ns, IR = 10 µA @ 25 °C | Higher reverse leakage may impact low-power standby performance | Acceptable where cost sensitivity outweighs leakage-critical standby requirements |
Compared with STTH2R02DJF and SB220-E3/52, the HS2D-T offers tighter reverse leakage (≤5 µA), JEDEC-compliant SMB packaging with J-STD-020 level 1 handling, and optimized thermal resistance for PCB-conducted cooling - making it preferred for space-constrained, thermally demanding industrial converters.

FAQ
What is the maximum repetitive peak reverse voltage rating for HS2D-T?
The HS2D-T has a repetitive peak reverse voltage (VRRM) rating of 200 V, as confirmed in the Absolute Maximum Ratings table. This value is fixed for the HS2D-T variant and distinguishes it from other members of the HS2x-T series (e.g., HS2G-T = 400 V). Exceeding this voltage risks avalanche breakdown and permanent device failure.
Does HS2D-T have a specified reverse recovery time, and how is it measured?
Yes, HS2D-T has a typical 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 parameter is verified per the Electrical Specifications section and applies only to the HS2D-T and HS2G-T variants - higher-voltage versions (HS2J-T through HS2M-T) specify 75 ns.
Is HS2D-T suitable for lead-free reflow soldering processes?
Yes, HS2D-T is qualified for lead-free reflow soldering. Its matte tin-plated leads meet J-STD-002 solderability requirements, and its moisture sensitivity level is rated at Level 1 per J-STD-020 - meaning it can be stored indefinitely in dry packs and placed directly into standard Pb-free reflow profiles without pre-baking.
What is the junction-to-lead thermal resistance (RθJL) of HS2D-T, and how is it validated?
The junction-to-lead thermal resistance (RθJL) of HS2D-T is 20 °C/W, measured with the device mounted on a 10 mm × 10 mm copper pad test board, as stated in the Thermal Performance section. This value is used to estimate die temperature rise above lead temperature under steady-state conduction and is not extrapolated from RθJA.
How does the forward voltage of HS2D-T vary with temperature and current?
HS2D-T forward voltage decreases with rising junction temperature: at 2 A, VF is 0.91 V at 25 °C and drops to 0.78 V at 125 °C. This negative temperature coefficient is documented in the Electrical Specifications table and supports stable current sharing in parallel configurations when properly heatsinked.
