Product details
Overview
HS3J R7G from Taiwan Semiconductor is a 600 V, 3 A high-efficiency surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring 1.7 V max forward voltage at 3 A and 75 ns reverse recovery time, used for freewheeling and high-frequency rectification in switching-mode power supplies.
For engineers reviewing the HS3J R7G datasheet, HS3J R7G pinout, HS3J R7G application, or HS3J R7G equivalent, key selection criteria include peak repetitive reverse voltage (600 V), average forward current (3 A), thermal resistance (60 °C/W), junction capacitance (50 pF), and RoHS/halogen-free compliance for industrial and telecom power designs.
Technical Context
This single-die standard recovery rectifier operates with a maximum junction temperature of 150 °C and is rated for 150 A non-repetitive surge current (8.3 ms half-sine). Its glass-passivated junction ensures stable performance under thermal cycling and humidity exposure.
The device exhibits low-profile mechanical construction per DO-214AB (SMC) outline, matte tin-plated leads compliant with J-STD-002 solderability, and meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| IF | 3 A continuous - suitable for mid-power output stages in AC/DC adapters and DC/DC converters |
| VF max | 1.7 V @ 3 A, 25°C - limits conduction loss to ≤5.1 W at full load |
| trr | 75 ns - enables operation up to ~2 MHz switching frequency before significant switching loss dominates |
| CJ | 50 pF @ 1 MHz, 4 V - reduces high-frequency noise coupling in fast-switching topologies |
| RθJA | 60 °C/W - requires ≥120 mm² copper pour for safe 3 A operation at 70°C ambient |
| IFSM | 150 A @ 8.3 ms - withstands inrush currents in hot-plug and capacitor-charging scenarios |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600 V, 3 A, 1.75 V VF, 60 ns trr, TO-277 package | Higher thermal resistance (75 °C/W), larger footprint than DO-214AB | Preferred where faster recovery is critical and board space allows TO-277 mounting |
| ON Semi MUR360 | 600 V, 3 A, 1.7 V VF, 60 ns trr, DO-201AD package | Higher RθJA (80 °C/W), axial-leaded - incompatible with automated SMT placement | Only suitable for through-hole prototyping or legacy repair; not recommended for new SMT designs |
Compared with STTH3L06S and MUR360, the HS3J R7G offers superior thermal performance (60 °C/W vs. ≥75 °C/W) and SMT compatibility in a low-profile DO-214AB package, making it optimal for space-constrained, high-volume power supply production.

FAQ
What is the maximum junction temperature rating for HS3J R7G?
The HS3J R7G has a maximum junction temperature (TJ) rating of +150 °C, verified per absolute maximum ratings table in the official TSC datasheet K2102. This allows operation in high-ambient environments such as enclosed server chassis or industrial enclosures when mounted on adequate copper area. Derating curves in Figure 1 confirm 3 A average forward current is sustainable up to 100 °C ambient with proper PCB thermal design.
Does HS3J R7G meet RoHS and halogen-free requirements?
Yes, HS3J R7G is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the "Features" section of the TSC HS3x datasheet K2102. The molding compound is UL 94V-0 rated, and terminals are matte tin-plated to meet J-STD-002 solderability standards - all confirmed in the Mechanical Data and Ordering Information sections.
What is the reverse recovery time (trr) specification for HS3J R7G?
The HS3J R7G has a maximum reverse recovery time (trr) of 75 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, per the Electrical Specifications table in the TSC K2102 datasheet. This value applies specifically to HS3J, HS3K, and HS3M variants - distinct from faster 50 ns versions in the HS3A–HS3G group.
Is HS3J R7G suitable for use in synchronous rectification circuits?
HS3J R7G is a standard recovery rectifier, not a Schottky or ultrafast device, so it is not recommended as a primary synchronous rectifier replacement. However, it functions reliably as a freewheeling diode alongside actively controlled MOSFETs in hybrid topologies. Its 75 ns trr and 1.7 V VF provide predictable behavior during dead-time conduction in buck-derived converters using HS3J R7G.
What marking code identifies HS3J R7G on the device body?
The HS3J R7G is marked with "HS3J" on the cathode-banded surface, per the Marking Diagram and Absolute Maximum Ratings table in the TSC K2102 datasheet. The "R7G" suffix denotes tape-and-reel packaging (3,000 pcs/reel) and green compound (G), consistent with TSC's ordering nomenclature defined in the Ordering Information section.
