Product details
Overview
HS2JA-T from Taiwan Semiconductor is a 600 V, 2 A surface-mount high-efficiency fast recovery rectifier diode in DO-214AC (SMA) package, featuring 75 ns reverse recovery time, 1.40 V max forward voltage at 2 A/25°C, and 12 pF junction capacitance - used in DC-DC converters and freewheeling paths where moderate voltage blocking and low switching loss are required.
For engineers reviewing the HS2JA-T datasheet, HS2JA-T pinout, HS2JA-T application, or HS2JA-T equivalent, key selection criteria include repetitive peak reverse voltage (600 V), thermal resistance (RθJL = 14 °C/W), reverse leakage (≤5 µA at 25°C), and compatibility with automated SMT placement on standard PCB pads.
Technical Context
The HS2JA-T is a single-die, glass-passivated silicon PN junction rectifier optimized for switching-mode power supplies. Its 600 V VRRM rating and 75 ns trr enable efficient operation in flyback and boost topologies up to several hundred kHz.
Thermal performance is defined with 5 mm × 5 mm copper pad mounting: RθJA = 86 °C/W (ambient), RθJC = 23 °C/W (case), and RθJL = 14 °C/W (lead), supporting continuous 2 A conduction at ≤150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse voltage before breakdown; sets usable input voltage range in offline SMPS |
| IF | 2 A - average forward current rating; defines continuous power handling with proper PCB heatsinking |
| trr | 75 ns - reverse recovery time; limits switching frequency and reduces turn-off losses in hard-switched converters |
| VF (max) | 1.70 V at 2 A / 25°C - forward voltage drop determines conduction loss and thermal load under full load |
| CJ | 12 pF - junction capacitance at 1 MHz / 4 V; affects high-frequency noise and snubber design |
| IR (max) | 5 µA at 25°C - low reverse leakage preserves efficiency in high-impedance bias networks and standby circuits |
| TJ max | +150 °C - maximum junction temperature; enables operation in compact, thermally constrained enclosures |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, cathode indicated by band. Matte tin-plated leads, moisture sensitivity level 1 (J-STD-020), UL 94V-0 molding compound.

| Cathode | Forward current exit / reverse voltage blocking terminal | Marked with band; connects to output rail or positive bus; withstands up to 600 V reverse bias |
Key Features
| Feature | Design Value |

| DO-214AC (SMA) package | Enables high-density layout and compatibility with standard SMT pick-and-place equipment |
| RoHS & halogen-free | Meets IEC 61249-2-21 and environmental compliance requirements for industrial and consumer end products |
Applications
| DC-DC Converter | Switching Inverter |
|---|---|
Use Scenario: Secondary-side rectification in isolated 24–48 V output buck-derived converters delivering up to 48 W. IC Role / Device Role / Timing Role: Output rectifier conducting during transformer reset phase; handles bidirectional flyback energy recovery. Use Value: 600 V rating accommodates reflected voltage spikes; 75 ns trr prevents cross-conduction loss with synchronous MOSFETs. | Use Scenario: Freewheeling path in half-bridge motor drive inverters operating at 20–50 kHz PWM frequency. IC Role / Device Role / Timing Role: Provides low-loss current recirculation path when upper/lower switches turn off. Use Value: 1.40 V typical VF at 2 A reduces conduction loss versus Schottky alternatives above 100 V, while maintaining thermal stability. |
| Freewheeling Diode | Offline SMPS Input Stage |

IC Role / Device Role / Timing Role: Clamps inductive kickback voltage to safe levels during switch turn-off. Use Value: 50 A IFSM surge rating absorbs short-duration transients; DO-214AC footprint allows direct replacement of legacy SMA devices. | Use Scenario: Bridge rectifier output stage in universal-input (85–265 V AC) offline flyback adapters rated ≤15 W. IC Role / Device Role / Timing Role: Converts rectified AC to pulsating DC prior to bulk capacitor filtering. Use Value: 600 V VRRM provides margin against line surges and transformer ringing; 12 pF CJ minimizes high-frequency coupling into control circuitry. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06 | 600 V VRRM, 2 A IF, 60 ns trr, TO-220AC package | Through-hole mounting; higher thermal mass but larger footprint and manual assembly | Preferred where board-level thermal management favors leaded packages or higher surge robustness is needed |
| ES2J | 600 V VRRM, 2 A IF, 75 ns trr, same DO-214AC package, VF ≈ 1.55 V @ 2 A | Identical mechanical fit and electrical envelope; minor VF variation within tolerance bands | Drop-in alternative with identical layout and thermal profile; verify IR and TJ derating per design margin |
Compared with STTH2R06 and ES2J, the HS2JA-T offers identical voltage/current ratings and recovery speed to ES2J with verified DO-214AC compatibility, while differing from STTH2R06 in mounting method and thermal path - making it optimal for space-constrained SMT designs requiring fast, reliable rectification at 600 V.

FAQ
What is the maximum repetitive peak reverse voltage rating for HS2JA-T?
The HS2JA-T has a maximum repetitive peak reverse voltage (VRRM) rating of 600 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version D2111), and defines the highest reverse-biased voltage the device can block repeatedly without breakdown under normal operating conditions. Exceeding this rating risks irreversible junction failure.
Does HS2JA-T support automated SMT placement?
Yes, HS2JA-T supports automated surface-mount placement. Its DO-214AC (SMA) package features matte tin-plated leads compliant with J-STD-002 solderability standards, and its marking code "HS2JA" and cathode band are machine-readable. The device is rated moisture sensitivity level 1 (per J-STD-020), eliminating bake requirements prior to reflow.
What is the forward voltage drop of HS2JA-T at 2 A and 25°C?
The forward voltage drop (VF) of HS2JA-T is 1.40 V maximum at 2 A and 25°C, with a typical value of 1.25 V under the same conditions. This specification is measured per pulse test (PW = 0.3 ms) and directly impacts conduction loss and thermal design in power stages using the HS2JA-T.
Is HS2JA-T RoHS and halogen-free compliant?
Yes, HS2JA-T is RoHS compliant and halogen-free per IEC 61249-2-21. The device uses lead-free matte tin plating on terminals and a halogen-free molding compound meeting UL 94V-0 flammability rating - verified in the Features section and Mechanical Data of the Taiwan Semiconductor HS2DA-T to HS2MA-T datasheet (D2111).
What is the reverse recovery time (trr) of HS2JA-T?
The reverse recovery time (trr) of HS2JA-T is 75 ns maximum, measured at IF = 0.5 A, IR = 1.0 A, and IRR = 0.25 A. This parameter is specified for the HS2JA-T, HS2KA-T, and HS2MA-T variants in the Electrical Specifications table and confirms suitability for medium-frequency switching applications up to ~500 kHz.
