Product details
Overview
HS1JFSH from Taiwan Semiconductor is a 1 A, 600 V high-efficiency surface-mount fast recovery rectifier in SOD-128 package, featuring 75 ns reverse recovery time, 1.02 V forward voltage at 1.0 A and 25°C, and AEC-Q101 qualification for automotive use in DC/DC converters and snubber circuits.
For engineers reviewing the HS1JFSH datasheet, HS1JFSH pinout, HS1JFSH application, or HS1JFSH equivalent, key selection criteria include peak reverse voltage (600 V), thermal resistance (RθJL = 29 °C/W), junction capacitance (13 pF), moisture sensitivity level (MSL 1), and compliance with automotive reliability standards.
Technical Context
The HS1JFSH employs a glass-passivated silicon die optimized for fast switching and low conduction loss, with a single-die configuration and cathode-band polarity indication. Its 75 ns reverse recovery time and 13 pF junction capacitance support high-frequency operation in power conversion stages.
Thermal performance is characterized by RθJL = 29 °C/W and RθJC = 22 °C/W on a 5 mm × 5 mm copper pad, enabling reliable 1 A continuous operation up to 150°C junction temperature under defined PCB layout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| trr | 75 ns - reverse recovery time at IF = 0.5 A, IR = 1.0 A, enables >100 kHz switching in flyback and boost converters |
| VF | 1.02 V @ 1.0 A, 25°C - forward voltage drop directly impacts conduction loss and thermal rise in high-duty-cycle operation |
| CJ | 13 pF @ 1 MHz, 4 V - junction capacitance affects high-frequency switching noise and EMI filter design |
| RθJL | 29 °C/W - junction-to-lead thermal resistance determines heatsinking requirements when mounted on PCB with standard pad |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06S | 600 V VRRM, 1 A IF, 75 ns trr, but TO-277A package (larger footprint, higher RθJA) | Requires PCB layout revision due to different outline and thermal pad geometry | Prefer HS1JFSH for SOD-128 footprint compatibility and lower profile in ultra-thin designs |
| ES1J | 600 V VRRM, 1 A IF, 35 ns trr, but no AEC-Q101 qualification and higher VF (1.7 V) | Limited to commercial-grade applications; unsuitable for automotive temperature cycling or long-life deployments | Choose HS1JFSH where automotive qualification, lower conduction loss, and MSL Level 1 are mandatory |
Compared with STTH1L06S and ES1J, the HS1JFSH delivers identical voltage/current ratings with superior automotive qualification, lower thermal resistance, and smaller SOD-128 footprint-making it optimal for space-constrained, high-reliability power conversion where layout reuse and supply chain continuity matter.

FAQ
What is the peak repetitive reverse voltage rating for HS1JFSH?
The HS1JFSH has a peak repetitive reverse voltage (VRRM) rating of 600 V, verified per the manufacturer's datasheet Absolute Maximum Ratings table. This value defines the maximum reverse-biased voltage the device can block continuously without breakdown, making HS1JFSH suitable for 48 V–400 V nominal bus applications with transient margin. It is not interchangeable with HS1KFSH (800 V) or HS1MFSH (1000 V) without circuit revalidation.
Is HS1JFSH qualified for automotive applications?
Yes, HS1JFSH is AEC-Q101 qualified, confirmed in the Features section of the official datasheet. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and unbiased highly accelerated stress testing (UHAST). HS1JFSH is intended for under-hood and cabin applications where automotive-grade reliability is mandatory, such as body control modules and DC/DC converters.
What is the forward voltage of HS1JFSH at 1.0 A and 125°C?
The forward voltage of HS1JFSH is 0.83 V (typical) and 1.02 V (maximum) at 1.0 A and 125°C, per the Electrical Specifications table. This lower VF at elevated temperature improves system efficiency in thermally demanding environments and reduces thermal runaway risk compared to higher-VF alternatives like ES1J. The value is measured under pulse conditions (PW = 0.3 ms).
Does HS1JFSH have a specified junction-to-ambient thermal resistance?
Yes, HS1JFSH has a junction-to-ambient thermal resistance (RθJA) of 51 °C/W, measured on a standard 5 mm × 5 mm copper pad test board per JEDEC JESD51-3. This value assumes natural convection and guides thermal design when forced airflow or additional copper is absent. For improved thermal performance, the lower RθJL = 29 °C/W should be used with direct lead-to-copper thermal paths.
What packaging and moisture sensitivity level does HS1JFSH use?
HS1JFSH is supplied in SOD-128 package on 14,000-piece tape-and-reel, with Moisture Sensitivity Level (MSL) 1 per J-STD-020. This means the device has unlimited floor life before reflow soldering and requires no baking prior to assembly-reducing manufacturing overhead and eliminating moisture-related popcorning risks in high-volume SMT lines.
