Product details
Overview
HS2GA-T from Taiwan Semiconductor is a 2A, 400V glass-passivated surface-mount rectifier diode in DO-214AC (SMA) package, featuring 1.03V max forward voltage at 2A/25°C, 50A surge current capability, and 20pF junction capacitance - deployed in DC-DC converter output stages for efficient power conversion.
For engineers reviewing the HS2GA-T datasheet, HS2GA-T pinout, HS2GA-T application, or HS2GA-T equivalent, key selection criteria include repetitive peak reverse voltage (400V), thermal resistance (RθJL = 14°C/W), reverse recovery time (≤50ns), and low-leakage performance (≤5µA @ 25°C) under switching-mode load conditions.
Technical Context
The HS2GA-T is a single-die, silicon planar junction rectifier optimized for high-efficiency switching applications. Its glass-passivated chip junction ensures stable reverse leakage (<5µA at 25°C) and robust moisture resistance (J-STD-020 Level 1).
Designed for automated SMT assembly, it delivers fast recovery (trr ≤ 50ns) and low forward conduction loss (VF = 1.03V max at 2A/25°C), enabling high-frequency operation in SMPS output rectification and freewheeling paths without thermal runaway.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum repetitive reverse blocking voltage; defines safe operating ceiling in flyback or buck output circuits |
| IF | 2 A - Continuous forward current rating; supports sustained 2A DC output in compact DC-DC modules |
| IFSM | 50 A - Peak non-repetitive surge current (8.3ms); handles inrush and transient overloads in power supplies |
| VF @ 2A/25°C | 1.03 V max - Low conduction loss reduces power dissipation and improves efficiency at full load |
| trr | ≤50 ns - Fast reverse recovery minimizes switching losses and EMI in >100kHz converters |

Applications
| DC-DC Converter Output Rectification | Switching Mode Inverter Freewheeling |
|---|---|
Use Scenario: Secondary-side rectification in isolated 24V–48V input DC-DC converters delivering up to 2A continuous output. IC Role / Device Role / Timing Role: Power rectifier converting high-frequency AC from transformer secondary into regulated DC output.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R04 | Same 2A/400V rating; trr = 45ns (slightly faster), VF = 1.15V max @ 2A - higher conduction loss | Preferred in ultra-low-noise designs where trr < 45ns is critical; less optimal for thermally constrained layouts | Select STTH2R04 only if trr reduction outweighs 0.12V higher VF impact on thermal design |
| MBR240 | Schottky structure; VF = 0.52V typ @ 2A but VRRM = 40V - unsuitable for 400V blocking | Valid only in low-voltage (<60V) DC-DC outputs; cannot replace HS2GA-T in 400V-rated systems | Reject MBR240 for any application requiring ≥300V reverse blocking; use only in sub-40V bias rails |
Compared with STTH2R04 and MBR240, the HS2GA-T uniquely balances 400V blocking, 1.03V conduction loss, and 50ns recovery in a cost-effective SMA package - making it the optimal choice for 200–500kHz industrial DC-DC converters needing reliability across extended temperature ranges.

FAQ
What is the maximum junction temperature rating for the HS2GA-T?
The HS2GA-T has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows continuous operation in high-ambient environments such as enclosed industrial power supplies. Derating begins above 75°C ambient, and the device must be mounted on a minimum 5mm × 5mm copper pad to maintain thermal integrity at full 2A load. The HS2GA-T's RθJL of 14°C/W supports this rating under standard JEDEC test conditions.
Does the HS2GA-T have a specified reverse recovery time (trr)?
Yes, the HS2GA-T has a specified reverse recovery time (trr) of ≤50ns under conditions of IF = 0.5A, IR = 1.0A, and Irr = 0.25A, per the Electrical Specifications table. This value is confirmed for both 25°C and 125°C junction temperatures and is critical for minimizing switching losses in high-frequency DC-DC converters. The HS2GA-T's trr is faster than HS2JA-T through HS2MA-T variants (75ns), confirming its optimization for speed-sensitive topologies.
Is the HS2GA-T RoHS and halogen-free compliant?
Yes, the HS2GA-T is fully RoHS compliant per EU Directive 2011/65/EU and halogen-free per IEC 61249-2-21. These compliance statements are explicitly documented in the FEATURES section of the official Taiwan Semiconductor datasheet (Version D2111). The device uses matte tin-plated leads and UL 94V-0 molding compound, satisfying environmental requirements for consumer, industrial, and automotive-qualified power designs.
What is the marking code printed on the HS2GA-T package?
The HS2GA-T is marked "HS2GA" on the device body, as confirmed in the Absolute Maximum Ratings table under "Marking code on the device." This 5-character laser marking appears adjacent to the cathode band on the DO-214AC (SMA) package and serves as the primary visual identifier for traceability and counterfeit prevention during incoming inspection or field verification.
Can the HS2GA-T be used in place of the HS2DA-T in a 200V design?
No, the HS2GA-T is not a direct substitute for the HS2DA-T in a 200V design because its VRRM is 400V - double the required rating - which may increase forward voltage (VF = 1.03V vs. 0.91V for HS2DA-T at 2A/25°C) and reduce system efficiency unnecessarily. While electrically safe, over-specifying voltage rating adds conduction loss without benefit. Use HS2DA-T where 200V blocking suffices; reserve HS2GA-T for designs requiring ≥350V working voltage margin.
