Product details
Overview
HS1JFS from Taiwan Semiconductor is a 1 A, 600 V repetitive peak reverse voltage (VRRM) surface-mount fast recovery rectifier in SOD-128 package, featuring 1.02 V typical forward voltage at 1.0 A and 25°C, 75 ns reverse recovery time, and 13 pF junction capacitance - optimized for DC-DC converters and switching-mode power supplies.
For engineers reviewing the HS1JFS datasheet, HS1JFS pinout, HS1JFS application, or HS1JFS equivalent, key selection criteria include its 600 V VRRM, thermal resistance of 29 °C/W (junction-to-lead), RoHS- and halogen-free compliance, and suitability for freewheeling and high-efficiency SMPS designs requiring low-profile SMD rectification.
Technical Context
The HS1JFS employs a glass-passivated silicon die with single-diode configuration, enabling fast switching and low conduction loss in compact SOD-128 packaging. Its 75 ns reverse recovery time and 13 pF junction capacitance support operation in high-frequency switching topologies up to several hundred kHz.
Thermal performance is defined by RθJL = 29 °C/W and RθJA = 51 °C/W on a 5 mm × 5 mm Cu pad PCB, allowing 1 A continuous forward current at ambient temperatures up to +75°C with proper layout - critical for space-constrained industrial and telecom power stages.
Key Specifications

| CJ @ 1 MHz, 4 V | 13 pF - limits capacitive coupling and EMI generation in high-dv/dt node placements |
| RθJL | 29 °C/W - enables direct thermal path to PCB copper; allows reliable 1 A operation with minimal external heatsink |
| IR @ 600 V, 125°C | 35 µA max - ensures low leakage in high-temperature hold-off conditions, e.g., standby mode |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06 | Same 1 A / 600 V rating; 75 ns trr; VF = 1.15 V max @ 1 A, 25°C; TO-277 package | TO-277 has higher RθJA (65 °C/W) and larger footprint than SOD-128 | Prefer HS1JFS for space-constrained SMT layouts; STTH1R06 suits through-hole or higher-power derating needs |
| ON Semi MUR1060 | 1 A / 600 V; 75 ns trr; VF = 1.7 V max @ 1 A, 25°C; DO-41 package | DO-41 requires manual assembly or wave soldering; no RoHS/halogen-free guarantee in base variant | HS1JFS preferred for automated production and environmental compliance; MUR1060 acceptable for legacy repair or cost-sensitive non-RoHS builds |
Compared with STTH1R06 and MUR1060, the HS1JFS delivers identical voltage/current ratings and recovery speed but offers superior thermal performance in SMT form factor, guaranteed halogen-free compliance, and tighter VF distribution - making it optimal for high-density, thermally demanding, and regulated markets.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for HS1JFS?
The HS1JFS has a VRRM of 600 V, meaning it can reliably block up to 600 V of reverse voltage in repetitive duty cycles. This rating is confirmed in the Absolute Maximum Ratings table and applies under standard test conditions (TA = 25°C). Exceeding this voltage risks avalanche breakdown and permanent device failure. The HS1JFS is part of a family spanning 200 V to 1000 V, with HS1JFS specifically designated for the 600 V grade.
What is the forward voltage (VF) of HS1JFS at 1.0 A and 25°C?
The HS1JFS exhibits a typical forward voltage of 1.02 V and a maximum of 1.70 V at 1.0 A and 25°C, as specified in the Electrical Specifications table. This VF value directly determines conduction loss (Pcond = IF × VF) and must be evaluated at operating temperature - at 125°C, VF drops to 0.83 V typical / 1.02 V max. The HS1JFS datasheet provides full VF curves across current and temperature.
Is HS1JFS RoHS and halogen-free compliant?
Yes, the HS1JFS is fully RoHS compliant and halogen-free per IEC 61249-2-21. This is explicitly stated in the FEATURES section and verified in the Mechanical Data table. Compliance applies to all materials including molding compound, lead frame, and plating. The HS1JFS meets JEDEC J-STD-020 moisture sensitivity level 1 and JESD 201 class 2 whisker resistance requirements - critical for automotive and industrial deployments.
What is the reverse recovery time (trr) of HS1JFS?
The HS1JFS has a maximum reverse recovery time (trr) of 75 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter is critical for minimizing switching losses in high-frequency converters. The trr remains stable across temperature, supporting consistent performance from −55°C to +150°C. The HS1JFS shares this trr spec with HS1KFS and HS1MFS but differs from faster HS1DFS/HS1GFS variants (50 ns).
What package type does HS1JFS use, and what are its key mechanical attributes?
The HS1JFS uses the SOD-128 surface-mount package, characterized by a low profile (<1.1 mm height), matte tin-plated leads solderable per J-STD-002, UL 94V-0 flammability rating, and 0.028 g weight. Polarity is marked by a cathode band. Its thermal metrics include RθJL = 29 °C/W and RθJA = 51 °C/W on a 5 mm × 5 mm Cu pad - all confirmed in the Mechanical Data and Thermal Performance sections of the HS1JFS datasheet.
