Product details
Overview
HS2GA from Taiwan Semiconductor is a 1.5A, 600V repetitive peak reverse voltage (VRRM) surface-mount fast recovery rectifier in DO-214AC (SMA) package, featuring 1.3V max forward voltage at 1.5A, 50ns reverse recovery time, and 50pF junction capacitance - deployed in DC-DC converters and snubber circuits.
For engineers reviewing the HS2GA datasheet, HS2GA pinout, HS2GA application, or HS2GA equivalent, key selection criteria include VRRM = 600V, IF = 1.5A, trr = 50ns, thermal resistance RθJA = 80°C/W, and DO-214AC mechanical compatibility with automated SMT assembly.
Technical Context
The HS2GA employs a single-die, glass-passivated silicon PN junction optimized for high-efficiency switching-mode power supplies. Its 600V VRRM rating supports medium-voltage flyback and forward converter topologies, while its 50ns trr enables operation up to several hundred kHz without excessive switching loss.
Thermal performance is defined by RθJA = 80°C/W under standard JEDEC PCB conditions, and the device operates across –55°C to +150°C junction temperature range. Moisture sensitivity level is J-STD-020 Level 1, enabling unlimited floor life before reflow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum non-repetitive reverse voltage the device blocks reliably in circuit |
| IF | 1.5 A - Continuous average forward current rating at TA = 25°C with adequate heatsinking |
| trr | 50 ns - Reverse recovery time measured at IF = 0.5A, IR = 1.0A, Irr = 0.25A; critical for minimizing switching loss in SMPS |
| VF (max) | 1.3 V - Forward voltage drop at IF = 1.5A and TJ = 25°C; determines conduction loss and thermal rise |
| CJ | 50 pF - Junction capacitance at 1 MHz and VR = 4.0V; impacts high-frequency noise and EMI behavior |
| RθJA | 80 °C/W - Junction-to-ambient thermal resistance on standard 1-inch² copper pad; defines required PCB copper area for thermal management |
Pinout & Package
Package: DO-214AC (SMA), molded plastic case with matte tin-plated leads, polarity indicated by cathode band, UL 94V-0 rated compound, weight ≈ 0.060 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of rectification path; must withstand surge current IFSM = 50A |
| Cathode | Forward current exit / reverse voltage blocking terminal | Marked by band; carries full VRRM = 600V when reverse-biased; critical for snubber node placement |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enhances long-term reliability and humidity resistance in industrial environments without hermetic sealing |
| Fast recovery (50 ns) | Reduces switching losses in 100–500 kHz DC-DC converters compared to standard recovery rectifiers |
| DO-214AC (SMA) package | Enables high-density automated placement and reflow soldering; compatible with IPC-7351B footprint standards |
| J-STD-020 Level 1 moisture sensitivity | Eliminates bake requirements prior to SMT assembly, reducing manufacturing overhead and risk of popcorning |
Applications
| DC-DC Converter | Snubber Circuit |
|---|---|
Use Scenario: Secondary-side rectification in isolated 24V–48V output flyback converters delivering up to 36W. IC Role / Device Role / Timing Role: Power rectifier converting high-frequency AC from transformer secondary into regulated DC output. Use Value: 600V VRRM safely handles reflected primary-side voltage spikes; 1.3V VF limits conduction loss at 1.5A load. | Use Scenario: RC snubber network across MOSFET drain-source in 65kHz PFC boost stage. IC Role / Device Role / Timing Role: Fast-recovery clamp diode absorbing inductive turn-off energy during MOSFET switching transitions. Use Value: 50ns trr ensures rapid turn-off to prevent voltage overshoot; low CJ minimizes capacitive loading on snubber resistor. |
| Switching Inverter | Freewheeling Diode |
Use Scenario: Output rectification in 12V input, 200V output push-pull inverter for LED driver applications. IC Role / Device Role / Timing Role: High-voltage output-stage rectifier handling bidirectional transformer leakage energy. Use Value: 150°C TJMAX supports sustained operation in enclosed luminaires; DO-214AC allows compact board layout. | Use Scenario: Inductive load freewheeling path in automotive HVAC blower motor control using N-channel MOSFET half-bridge. IC Role / Device Role / Timing Role: Unidirectional current path releasing stored inductor energy when main switch turns off. Use Value: 50A IFSM withstands motor stall surges; glass passivation prevents degradation under cyclic thermal stress. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L60S | VRRM = 600V, IF = 1.0A, trr = 35ns, DO-214AC | Lower IF rating requires derating above 1.0A; faster trr suits >1MHz designs | Select if higher switching frequency dominates over current capacity |
| ES1J | VRRM = 600V, IF = 1.0A, trr = 35ns, DO-214AC | Same package but 0.5A lower IF; tighter VF distribution (1.15V typ) | Prefer for cost-sensitive, thermally relaxed 1A designs where 50ns trr is sufficient |
Compared with STTH1L60S and ES1J, the HS2GA delivers higher continuous current (1.5A vs. 1.0A) at identical 600V VRRM, trading slightly slower recovery (50ns vs. 35ns) for improved thermal margin and surge robustness in 36W+ power stages.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of the HS2GA?
The HS2GA has a VRRM rating of 600 V, as confirmed in the Absolute Maximum Ratings table of the J2102 datasheet. This value defines the highest reverse voltage the device can block repeatedly without breakdown under normal operating conditions. Exceeding 600 V risks irreversible avalanche failure. The HS2GA is part of the HS2AA–HS2MA family, where 'G' explicitly denotes the 600V grade.
What is the forward voltage (VF) specification for HS2GA at rated current?
The HS2GA exhibits a maximum forward voltage of 1.3 V at IF = 1.5 A and TJ = 25°C, per the Electrical Specifications table. This parameter directly impacts conduction loss and thermal design - at full load, it contributes ~1.95 W of dissipation. The actual VF decreases with lower junction temperature and increases at elevated TJ.
Does HS2GA have a specified reverse recovery time (trr) and how is it measured?
Yes, the HS2GA has a maximum reverse recovery time (trr) of 50 ns, measured under the condition IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, as stated in the Electrical Specifications section. This test reflects real-world switching behavior in hard-switched converters and is critical for estimating dynamic losses and EMI generation.
What package type does HS2GA use and what are its key mechanical attributes?
The HS2GA uses the DO-214AC (SMA) package: a surface-mount, low-profile plastic case with matte tin-plated leads compliant with J-STD-002 solderability. It features a cathode band for polarity identification, weighs approximately 0.060 g, and meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance standards.
Is HS2GA RoHS compliant and halogen-free?
Yes, the HS2GA is RoHS compliant and halogen-free in accordance with IEC 61249-2-21, as explicitly stated in the FEATURES section of the J2102 datasheet. These compliance statements apply to the entire HS2AA–HS2MA series, including the HS2GA variant, and are verified through material declarations and third-party testing.
