Product details
Overview
HS2GH from Taiwan Semiconductor is a 400 V repetitive peak reverse voltage, 2 A average forward current, surface-mount fast recovery rectifier in DO-214AA (SMB) package, featuring 1.3 V typical forward voltage at 2 A and 50 ns reverse recovery time - deployed in automotive DC-DC converters and freewheeling circuits.
For engineers reviewing the HS2GH datasheet, HS2GH pinout, HS2GH application, or HS2GH equivalent, key selection criteria include its 400 V VRRM, 50 ns trr, 1.3 V VF at 2 A, DO-214AA thermal resistance of 80 °C/W, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This discrete high-efficiency rectifier uses a glass-passivated single die construction with fast switching characteristics. Its 50 ns reverse recovery time and low junction capacitance (50 pF at 1 MHz, 4 V) support high-frequency operation in snubber and flyback topologies.
The device operates across -55 °C to +150 °C junction temperature range and sustains 50 A non-repetitive surge current (8.3 ms half-sine). Its matte tin-plated leads comply with J-STD-002 solderability and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum repetitive reverse blocking voltage, defines usable DC bus or flyback clamp voltage rating |
| IF | 2 A - continuous average forward current at TA = 75 °C, sets steady-state power handling limit |
| VF | 1.3 V (typ) @ 2 A, 25 °C - forward conduction loss directly impacts efficiency in high-duty-cycle rectification |
| trr | 50 ns - fast recovery enables >100 kHz switching in SMPS without excessive switching loss or ringing |
| RθJA | 80 °C/W - thermal resistance from junction to ambient, determines required PCB copper area for thermal management |
| IR | 5 µA (max) @ 400 V, 25 °C - low leakage preserves efficiency in high-impedance hold-up or sensing paths |
Pinout & Package
DO-214AA (SMB) surface-mount package with cathode-indicated band; 0.090 g mass; UL 94V-0 molding compound; matte tin-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., switch node in buck/flyback); polarity must match layout marking |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; ties to higher-potential rail (e.g., output capacitor positive); critical for reverse voltage stress assignment |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood applications including temperature cycling, humidity bias, and mechanical shock |
| Glass-passivated junction | Enhances long-term reliability and moisture resistance versus epoxy-passivated alternatives |
| Fast recovery (50 ns) | Reduces switching losses and EMI in 100–500 kHz DC-DC converters compared to standard rectifiers |
| Halogen-free per IEC 61249-2-21 | Meets RoHS and automotive OEM material compliance requirements for end-of-life processing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R04 | 400 V VRRM, 2 A IF, 50 ns trr, but TO-220AC package (not surface-mount) | Requires through-hole mounting and larger board area; unsuitable for high-density automotive PCBs | Select HS2GH when DO-214AA SMT footprint, automated placement, and AEC-Q101 compliance are mandatory |
| ON Semi MUR240 | 400 V VRRM, 2 A IF, 50 ns trr, DO-214AA package, but not AEC-Q101 qualified | Lacks automotive qualification; limited to industrial/commercial environments without temperature cycling or vibration stress | Choose HS2GH where automotive reliability validation and halogen-free compliance are required |
Compared with STTH2R04 and MUR240, HS2GH uniquely combines AEC-Q101 qualification, DO-214AA SMT packaging, and verified 400 V/2 A/50 ns performance - enabling drop-in use in space-constrained, thermally demanding automotive power stages without redesign.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for HS2GH?
The HS2GH has a maximum repetitive peak reverse voltage (VRRM) of 400 V, as specified in the Absolute Maximum Ratings table. This rating defines the highest reverse voltage the device can block repeatedly without breakdown under normal operating conditions and is validated per JEDEC standards. The HS2GH is part of the HS2AH–HS2MH family where 'G' explicitly denotes the 400 V variant.
Is HS2GH qualified for automotive applications?
Yes, HS2GH is AEC-Q101 qualified, confirming its suitability for automotive underhood and cabin applications. This qualification includes stress testing for temperature cycling, high-temperature operating life, and mechanical shock. The device's glass-passivated junction, halogen-free construction, and JESD 201 Class 2 whisker resistance further support automotive reliability requirements.
What is the forward voltage (VF) of HS2GH at rated current?
The HS2GH exhibits a typical forward voltage (VF) of 1.3 V at 2 A forward current and 25 °C junction temperature, as stated in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and directly impacts conduction loss in power conversion stages - critical for thermal design in compact automotive modules.
Does HS2GH have a defined reverse recovery time (trr)?
Yes, HS2GH has a reverse recovery time (trr) of 50 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This fast recovery characteristic enables efficient operation in high-frequency switching power supplies (e.g., >100 kHz DC-DC converters), reducing switching losses and electromagnetic interference compared to standard recovery rectifiers.
What package type does HS2GH use, and what are its key mechanical features?
HS2GH uses the DO-214AA (SMB) surface-mount package. Key mechanical features include a UL 94V-0 flammability-rated molding compound, matte tin-plated leads compliant with J-STD-002 solderability, polarity indicated by a cathode band, and a nominal weight of 0.090 g. The package supports automated placement and reflow soldering per industry standards.
