Product details
Overview
HS2JH from Taiwan Semiconductor is a 600 V, 2 A surface-mount fast recovery rectifier diode in DO-214AA (SMB) package, featuring 75 ns reverse recovery time, 1.7 V forward voltage at 2 A, and 5 µA reverse leakage at 25°C. It serves as a freewheeling or snubber diode in automotive DC-DC converters and LED lighting circuits.
For engineers reviewing the HS2JH datasheet, HS2JH pinout, HS2JH application, or HS2JH equivalent, key selection criteria include peak reverse voltage (600 V), thermal resistance (80 °C/W), junction temperature range (–55 to +150 °C), and AEC-Q101 qualification for automotive reliability.
Technical Context
The HS2JH is a single-die, glass-passivated silicon rectifier optimized for high-efficiency switching applications. Its 75 ns trr and low CJ (30 pF) support fast turn-off in flyback and boost topologies, while its 50 A IFSM rating enables robust surge handling during transient events.
Designed for automated SMT placement, the device uses matte tin-plated leads compliant with J-STD-002 and meets JESD201 Class 2 whisker resistance. Polarity is marked by a cathode band on the DO-214AA molded case.
Key Specifications

| IF | 2 A - continuous average forward current under specified thermal conditions |
| VF @ 2 A | 1.7 V - forward conduction loss impacting power stage efficiency and thermal design |
| trr | 75 ns - reverse recovery time determining switching losses and EMI in high-frequency converters |
| RθJA | 80 °C/W - junction-to-ambient thermal resistance defining required PCB copper area for thermal management |
| IR @ 25°C | 5 µA - reverse leakage current affecting standby power and high-impedance sensing accuracy |
| TJ max | +150 °C - maximum allowable junction temperature enabling operation in under-hood automotive environments |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06 | Same VRRM (600 V), IF (2 A), but VF = 1.55 V typ @ 2 A; trr = 60 ns; TO-220AC package | Requires through-hole mounting and heatsinking; higher thermal mass slows transient response | Prefer when board-level thermal management allows larger package and lower VF is critical |
| ES2J | Same DO-214AA package and VF (1.7 V), but VRRM = 600 V, trr = 35 ns, IR = 10 µA @ 25°C | Lower trr reduces EMI in >500 kHz designs; higher IR may affect ultra-low-power standby | Choose when faster switching is prioritized and leakage sensitivity is low |
Compared with STTH2R06 and ES2J, the HS2JH offers AEC-Q101 qualification and tighter IR spec (5 µA), making it preferred for automotive-grade designs where reliability and low leakage are mandatory, despite slightly slower trr than ES2J.

FAQ
What is the peak repetitive reverse voltage rating for HS2JH?
The HS2JH has a peak repetitive reverse voltage (VRRM) rating of 600 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version A2102). The HS2JH must not be subjected to reverse voltages exceeding this limit to ensure reliable long-term operation without avalanche breakdown or parametric shift.
Is HS2JH qualified for automotive applications?
Yes, the HS2JH is explicitly AEC-Q101 qualified per the manufacturer's documentation. This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD), confirming suitability for under-hood and safety-critical automotive subsystems such as body control modules and LED lighting drivers.
What is the forward voltage drop of HS2JH at rated current?
The HS2JH exhibits a typical forward voltage (VF) of 1.7 V at 2 A and 25°C junction temperature, as specified in the Electrical Specifications table. This value increases with temperature and current; at 125°C, VF rises to approximately 1.45 V due to negative temperature coefficient behavior of silicon PN junctions.
Does HS2JH have a defined reverse recovery time?
Yes, the HS2JH has a specified reverse recovery time (trr) of 75 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter is measured per JEDEC standard and directly impacts switching loss and EMI generation in high-frequency power converters using the HS2JH as a freewheeling or snubber diode.
What package type does HS2JH use and what are its key mechanical features?
The HS2JH uses the DO-214AA (SMB) surface-mount package. Key mechanical features include a UL 94V-0 compliant molding compound, matte tin-plated leads meeting J-STD-002 solderability requirements, JESD201 Class 2 whisker resistance, and polarity indicated by a visible cathode band - all verified in the Mechanical Data section of the Taiwan Semiconductor datasheet.
