Product details
Overview
HS1JH from Taiwan Semiconductor is a 600 V, 1 A glass-passivated surface-mount fast recovery rectifier in DO-214AC (SMA) package, with 1.7 V forward voltage at 1 A and 75 ns reverse recovery time, used in DC-DC converters and snubber circuits for high-efficiency power conversion.
For engineers reviewing the HS1JH datasheet, HS1JH pinout, HS1JH application, or HS1JH equivalent, key selection criteria include peak reverse voltage (600 V), forward current rating (1 A), thermal resistance (15 °C/W junction-to-lead), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
The HS1JH operates as a single-die, unidirectional silicon rectifier with fast recovery characteristics optimized for switching-mode power supplies. Its 75 ns trr and low 15 pF junction capacitance support high-frequency operation up to several hundred kHz.
Thermally, it delivers 15 °C/W junction-to-lead resistance when mounted on a 5 mm × 5 mm copper pad, enabling reliable 1 A continuous conduction at TJ ≤ 150 °C. The device features glass-passivated junctions and meets JESD201 Class 2 whisker resistance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06 | Same 600 V VRRM, 1 A IF, but VF = 1.75 V (typ), trr = 60 ns, DO-214AC package | Slightly faster recovery but higher VF increases conduction loss at high duty cycles | Prefer HS1JH where thermal management is constrained; STTH1R06 suits ultra-high-frequency designs >300 kHz |
| ES1J | 600 V VRRM, 1 A IF, VF = 1.7 V, trr = 35 ns, same DO-214AC package, no AEC-Q101 qualification | Lacks automotive qualification; not recommended for under-hood or safety-critical systems | Select HS1JH for automotive or industrial applications requiring AEC-Q101; ES1J acceptable for commercial-grade consumer power supplies |
Compared with STTH1R06 and ES1J, the HS1JH offers balanced trade-offs: identical voltage/current ratings, AEC-Q101 qualification absent in ES1J, and superior thermal resistance (15 °C/W vs. STTH1R06's 18 °C/W), making it optimal for thermally dense automotive power modules.

FAQ
What is the peak repetitive reverse voltage rating of the HS1JH?
The HS1JH 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 B2401). It defines the maximum reverse-biased voltage the device can block repeatedly without breakdown, making HS1JH suitable for 400 V DC bus applications with 1.5× safety margin. Exceeding this rating risks avalanche failure or permanent junction damage.
Is the HS1JH qualified for automotive applications?
Yes, the HS1JH is explicitly AEC-Q101 qualified per the manufacturer's documentation. This qualification covers stress tests including temperature cycling, humidity bias HAST, and mechanical shock, validating its use in automotive power electronics such as body control modules and LED lighting drivers. The HS1JH's -55°C to +150°C operating range and JESD201 Class 2 whisker resistance further support under-hood deployment.
What is the forward voltage drop of the HS1JH at 1 A and 25°C?
The forward voltage (VF) of the HS1JH is 1.7 V maximum at IF = 1 A and TJ = 25°C, as specified in the Electrical Specifications table. This value reflects worst-case conduction loss under nominal conditions; typical VF is lower. At elevated temperatures (e.g., 125°C), VF decreases slightly (~1.55 V), reducing conduction loss but requiring thermal design to maintain junction temperature within limits.
Does the HS1JH have a defined reverse recovery time, and what is its value?
Yes, the HS1JH has a specified reverse recovery time (trr) of 75 ns maximum, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter is critical for high-frequency switching applications like DC-DC converters, where shorter trr reduces switching losses and EMI. The 75 ns value places HS1JH in the fast recovery category-slower than ultrafast diodes (<50 ns) but faster than standard rectifiers (>500 ns).
What package type does the HS1JH use, and are its dimensions standardized?
The HS1JH uses the DO-214AC (SMA) package, fully compliant with JEDEC DO-214AC standards. Dimensions-including body length (4.06–4.60 mm), width (2.29–2.83 mm), and height (2.30–2.50 mm)-are documented in the Package Outline Dimensions section. The cathode is marked by a visible band, and the matte tin-plated leads meet J-STD-002 solderability requirements, ensuring compatibility with standard SMT reflow profiles.
