Product details
Overview
HS2DH from Taiwan Semiconductor is a 2 A, 200 V repetitive peak reverse voltage (VRRM) surface-mount fast recovery rectifier in DO-214AA (SMB) package, featuring 50 ns reverse recovery time (trr), 1.0 V forward voltage at 2 A, and AEC-Q101 qualification for automotive use in snubber and freewheeling circuits.
For engineers reviewing the HS2DH datasheet, HS2DH pinout, HS2DH application, or HS2DH equivalent, key selection criteria include its 200 V VRRM, 50 ns trr, 1.0 V VF at 2 A, AEC-Q101 qualification, and DO-214AA mechanical compatibility in space-constrained DC-DC and automotive lighting designs.
Technical Context
The HS2DH employs a glass-passivated single-die silicon junction optimized for fast switching with low conduction loss. Its 50 ns reverse recovery time enables high-frequency operation in flyback and boost converters without excessive switching loss.
Thermal performance is defined by an 80 °C/W junction-to-ambient thermal resistance (RθJA) under standard PCB mounting, supporting continuous 2 A forward current (IF) up to 150 °C junction temperature, with surge capability of 50 A IFSM (8.3 ms half-sine).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum non-repetitive reverse blocking voltage, sets usable input range in 24 V automotive DC-DC stages |
| IF | 2 A - continuous average forward current rating at TA = 75 °C, defines steady-state power handling |
| trr | 50 ns - measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables ≤500 kHz switching in hard-switched topologies |
| VF | 1.0 V @ 2 A, 25 °C - directly determines conduction loss (2 W max at full load), critical for thermal budget |
| Junction temp | –55 to +150 °C - supports under-hood automotive environments and industrial ambient extremes |
| CJ | 50 pF @ 4 V, 1 MHz - impacts EMI filtering design and high-frequency turn-off behavior |
Pinout & Package
DO-214AA (SMB) surface-mount package with cathode-indicated band; matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance; UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck converter); polarity must match PCB silkscreen |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; ties to higher-potential rail (e.g., output capacitor positive); defines unidirectional conduction path |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per stress test requirements |
| Glass passivated junction | Enhances moisture resistance and long-term stability of reverse leakage (IR ≤ 5 µA @ 25 °C) |
| Fast recovery (50 ns) | Reduces switching loss and diode-induced ringing in high-frequency SMPS, enabling smaller passive components |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS directives for environmentally regulated end equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R02 | Same 200 V VRRM, 2 A IF, but trr = 35 ns and VF = 1.15 V @ 2 A; DO-214AA package | Better trr suits >1 MHz ZVS designs; higher VF increases conduction loss | Select STTH2R02 when faster recovery outweighs forward loss penalty in high-frequency converters |
| SB220 | 200 V VRRM, 2 A IF, but trr = 150 ns and VF = 0.95 V @ 2 A; same DO-214AA package | Slower recovery increases switching loss but lower VF improves light-load efficiency | Select SB220 where cost sensitivity and low-VF dominate over EMI constraints in <300 kHz designs |
Compared with STTH2R02 and SB220, the HS2DH delivers balanced performance: its 50 ns trr and 1.0 V VF support mid-frequency (200–500 kHz) automotive and industrial supplies without compromising thermal margin or EMI compliance.

FAQ
What is the peak repetitive reverse voltage rating for HS2DH?
The HS2DH has a peak repetitive reverse voltage (VRRM) rating of 200 V, verified per Taiwan Semiconductor's A2102 datasheet revision. This rating defines the maximum allowable reverse-biased voltage the device can block repeatedly without breakdown, making it suitable for 24 V and 48 V automotive and industrial bus applications where transient overvoltages remain within this limit. The HS2DH must not be operated beyond 200 V VRRM in continuous or repetitive conditions.
Is HS2DH qualified for automotive applications?
Yes, the HS2DH is AEC-Q101 qualified, as explicitly stated in the Taiwan Semiconductor datasheet. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and unbiased highly accelerated stress testing (UHAST), confirming suitability for under-hood and cabin automotive systems such as LED lighting and body control modules. The HS2DH meets all required failure rate and reliability thresholds defined in AEC-Q101 Rev D.
What is the forward voltage drop of HS2DH at rated current?
The HS2DH exhibits a typical forward voltage (VF) of 1.0 V at 2 A forward current and 25 °C junction temperature, per electrical specifications in the A2102 datasheet. This value is measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating effects. At elevated temperatures or higher currents, VF will increase slightly due to positive temperature coefficient, but remains within 1.15 V up to 125 °C.
Does HS2DH have a specified reverse recovery time?
Yes, the HS2DH has a maximum reverse recovery time (trr) of 50 ns, tested under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter is critical for minimizing switching losses and voltage overshoot in high-frequency DC-DC converters. The 50 ns trr is confirmed across the HS2AH–HS2GH subgroup, including the HS2DH, and is validated at both 25 °C and 125 °C junction temperatures.
What package type does HS2DH use, and what are its key mechanical features?
The HS2DH uses the DO-214AA (SMB) surface-mount package, with dimensions and pad layout defined in Taiwan Semiconductor's A2102 package outline drawing. Key mechanical features include matte tin-plated leads compliant with J-STD-002 solderability, UL 94V-0 flammability-rated epoxy molding compound, and cathode polarity indicated by a visible band. The device weighs approximately 0.090 g and passes JESD 201 Class 2 whisker testing.
