Product details
Overview
HS2JAH from Taiwan Semiconductor is a 1.5A, 600V AEC-Q101-qualified surface-mount fast recovery rectifier in DO-214AC (SMA) package, featuring 75 ns reverse recovery time, 1.7 V forward voltage at 1.5 A, and 30 pF junction capacitance - deployed in automotive DC-DC converters and freewheeling circuits.
For engineers reviewing the HS2JAH datasheet, HS2JAH pinout, HS2JAH application, or HS2JAH equivalent, key selection criteria include peak repetitive reverse voltage (600 V), surge current rating (50 A), thermal resistance (80 °C/W), junction temperature range (–55 to +150 °C), and AEC-Q101 qualification for automotive reliability.
Technical Context
The HS2JAH employs a single-die, glass-passivated PN junction optimized for fast switching with controlled reverse recovery behavior. Its 75 ns trr and low 30 pF CJ support high-frequency operation in snubber and flyback topologies.
Rated for 1.5 A average forward current and 50 A non-repetitive surge, the device operates across –55 °C to +150 °C junction temperature and meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse blocking voltage; defines usable input voltage headroom in DC-DC and snubber circuits |
| IF | 1.5 A - continuous forward current rating; sets thermal design baseline for PCB trace width and copper area |
| trr | 75 ns - measured under IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; determines switching loss and EMI in high-frequency converters |
| VF | 1.7 V @ 1.5 A, 25°C - forward conduction loss contributor; impacts efficiency and thermal rise in freewheeling paths |
| CJ | 30 pF @ 1 MHz, VR = 4 V - junction capacitance affecting high-frequency turn-off behavior and ringing |
| RθJA | 80 °C/W - junction-to-ambient thermal resistance; used to calculate temperature rise on standard FR-4 with minimal copper |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and UHAST |

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 | 600 V, 1 A, 60 ns trr, TO-277 package | Lower current rating; smaller footprint but no AEC-Q101 qualification | Preferred where space is constrained and automotive qualification is not required |
| ON Semi MUR160 | 600 V, 1 A, 50 ns trr, DO-41 package | Through-hole mounting; faster recovery but lower surge rating (30 A) and no AEC-Q101 | Suitable for legacy industrial designs with manual assembly or prototyping |
Compared with STTH1L60S and MUR160, the HS2JAH delivers higher current (1.5 A vs. 1 A), automotive qualification, and surface-mount compatibility - making it optimal for volume automotive and industrial power supplies where reliability, thermal performance, and SMT scalability are critical.

FAQ
What is the peak repetitive reverse voltage rating for HS2JAH?
The HS2JAH has a peak repetitive reverse voltage (VRRM) rating of 600 V. This value is specified in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version A2102) and defines the maximum reverse-biased voltage the device can block repeatedly without breakdown. It is critical for ensuring safe operation in automotive battery-supplied circuits subject to load dump transients.
Is HS2JAH qualified for automotive applications?
Yes, the HS2JAH is AEC-Q101 qualified per the manufacturer's documentation. This qualification includes stress testing for temperature cycling, high-temperature reverse bias (HTRB), and unbiased highly accelerated stress test (UHAST), confirming suitability for under-hood and safety-critical automotive power systems. The HS2JAH datasheet explicitly lists AEC-Q101 in its FEATURES section.
What is the forward voltage drop of HS2JAH at rated current?
The HS2JAH exhibits a maximum forward voltage (VF) of 1.7 V at 1.5 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 typical of silicon rectifiers.
What package type does HS2JAH use, and what are its key mechanical properties?
The HS2JAH uses the DO-214AC (SMA) package: a low-profile, surface-mount outline with matte tin-plated leads, UL 94V-0 compliant molding compound, and cathode polarity marked by a visible band. Its weight is approximately 0.060 g, and it meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity standards.
How does the reverse recovery time of HS2JAH compare to lower-voltage variants in the same family?
The HS2JAH has a reverse recovery time (trr) of 75 ns, which is higher than the 50 ns of HS2AAH–HS2GAH variants (50–400 V). This trade-off reflects the physics of higher-voltage junction design: wider depletion regions increase minority carrier lifetime, resulting in longer trr. Engineers selecting HS2JAH should account for this in EMI filtering and loss budgeting at >200 kHz switching frequencies.
