Product details
Overview
HS1B R3G from Taiwan Semiconductor is a 1 A, 100 V glass-passivated surface-mount silicon rectifier diode in DO-214AC (SMA) package, optimized for fast switching in DC/DC converters and snubber circuits with 50 ns reverse recovery time and 1.0 V forward voltage at 1 A.
For engineers reviewing the HS1B R3G datasheet, HS1B R3G pinout, HS1B R3G application, or HS1B R3G equivalent, key selection criteria include its 100 V repetitive peak reverse voltage, 30 A surge rating, 15 °C/W junction-to-lead thermal resistance, RoHS/halogen-free compliance, and suitability for automated SMT assembly on industrial power supplies and lighting drivers.
Technical Context
This single-die standard recovery rectifier operates with a maximum junction temperature of 150 °C and features moisture sensitivity level 1 per J-STD-020. Its 1.0 V forward voltage at 1 A and 5 µA reverse leakage at 25 °C support high-efficiency operation in low-voltage switching topologies.
The device uses a glass-passivated PN junction and exhibits 20 pF junction capacitance at 1 MHz and 4 V reverse bias. Thermal performance is characterized with 15 °C/W junction-to-lead and 70 °C/W junction-to-ambient resistance on a 5 mm × 5 mm copper pad PCB.

FAQ
What is the maximum junction temperature rating for HS1B R3G?
The HS1B R3G has a maximum junction temperature (TJ) rating of +150 °C, enabling reliable operation in industrial environments with elevated ambient temperatures. This rating is supported by its 15 °C/W junction-to-lead thermal resistance and UL 94V-0 mold compound. Derating curves in the datasheet specify usable current versus case temperature, and HS1B R3G must be mounted on a minimum 5 mm × 5 mm copper pad to achieve thermal specifications.
Does HS1B R3G meet RoHS and halogen-free requirements?
Yes, HS1B R3G is RoHS compliant and halogen-free per TSC's M2401 specification. The device uses lead-free matte tin plating on leads and halogen-free molding compound, satisfying IEC 61249-2-21 and JEDEC J-STD-609A Class 1 requirements. These attributes make HS1B R3G suitable for export to EU, China, and other regulated markets without additional compliance screening.
What is the reverse recovery time (trr) of HS1B R3G and how is it measured?
The reverse recovery time (trr) of HS1B R3G is 50 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the datasheet. This value reflects its performance as a fast standard recovery rectifier and is validated using the test circuit shown in Figure 10 of the TSC document. HS1B R3G's trr is lower than HS1G–HS1M variants but higher than ultrafast types, making it appropriate for 100–500 kHz switching applications.
Is HS1B R3G suitable for automated SMT placement?
Yes, HS1B R3G is explicitly designed for automated placement, with moisture sensitivity level 1 per J-STD-020, eliminating bake requirements before reflow. Its DO-214AC (SMA) package has standardized dimensions, matte tin-plated leads compliant with J-STD-002, and a cathode band for optical recognition. TSC confirms HS1B R3G is qualified for high-speed pick-and-place systems used in volume manufacturing of power supplies and lighting drivers.
What is the marking code and package type of HS1B R3G?
The HS1B R3G is marked "HS1B" on the device body and packaged in DO-214AC (SMA), a JEDEC-standard surface-mount outline with 4.60 mm × 2.83 mm body dimensions and 1.58 mm lead width. The "R3G" suffix denotes tape-and-reel packaging (7,500 units per reel) and green compound (halogen-free). Polarity is indicated by a cathode band near the cathode terminal.
