Product details
Overview
HS3GB R5G from Taiwan Semiconductor is a 3 A, 400 V repetitive peak reverse voltage (VRRM) surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring 1.3 V max forward voltage at 3 A, 50 ns reverse recovery time, and glass passivated junction for high reliability in switching power supplies.
For engineers reviewing the HS3GB R5G datasheet, HS3GB R5G pinout, HS3GB R5G application, or HS3GB R5G equivalent, key selection criteria include its 400 V VRRM, 100 A IFSM surge rating, 60 °C/W junction-to-ambient thermal resistance, moisture sensitivity level 1 compliance, and suitability for automated SMT assembly in compact AC/DC adapters and display power stages.
Technical Context
The HS3GB R5G is a single-die, fast-recovery rectifier optimized for high-frequency switching operation in offline SMPS topologies. Its 50 ns trr and low 1.3 V VF at rated current reduce conduction and switching losses, while the glass-passivated junction ensures stable performance under thermal cycling and humidity stress.
Designed for DO-214AA (SMB) mounting, it supports lead-free reflow per J-STD-020 Level 1 and meets JESD201 Class 2 whisker resistance. The cathode band polarity marking and matte tin-plated leads ensure reliable solderability and board-level traceability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast-recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L04 | 400 V VRRM, 3 A IF, 50 ns trr, but TO-220AC package (through-hole) | Requires PCB through-hole mounting and larger board area; unsuitable for fully SMT designs | Select when legacy through-hole assembly or higher thermal mass is required |
| ON Semi MUR340 | 400 V VRRM, 3 A IF, 50 ns trr, DO-214AA package, but 1.45 V VF max at 3 A | Higher forward drop increases conduction loss by ~115 mW at full load vs. HS3GB R5G | Select when second-source qualification is mandated and 0.15 V VF penalty is acceptable |
Compared with STTH3L04 and MUR340, the HS3GB R5G delivers identical 400 V/3 A/50 ns performance in an SMT-optimized DO-214AA package with the lowest VF (1.3 V) among alternatives-directly improving thermal margin and efficiency in space-constrained adapters and displays.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for HS3GB R5G?
The HS3GB R5G has a VRRM of 400 V, confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version L2102). This rating defines the highest reverse voltage the device can block repeatedly without breakdown and is validated across temperature and lifetime stress tests. The "GB" suffix in HS3GB R5G explicitly denotes the 400 V grade within the HS3x family.
Does HS3GB R5G support lead-free reflow soldering?
Yes, HS3GB R5G supports lead-free reflow soldering and is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it can be stored indefinitely at ambient conditions without baking prior to assembly. Its matte tin-plated leads meet J-STD-002 solderability requirements, and the DO-214AA package is qualified for standard Pb-free reflow profiles up to 260 °C peak temperature.
What is the typical forward voltage drop of HS3GB R5G at 3 A?
The HS3GB R5G exhibits a maximum forward voltage (VF) of 1.3 V at 3 A and 25 °C junction temperature, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating effects. At elevated temperatures (e.g., 100 °C), VF decreases slightly due to semiconductor physics, remaining well within design margins for thermal stability.
Is HS3GB R5G suitable for use in TV power supplies?
Yes, HS3GB R5G is explicitly listed in the Applications section of its datasheet for TV power supplies. Its 400 V VRRM, 3 A IF, and 50 ns trr align with secondary-side rectification requirements in modern 50–200 W TV SMPS designs. The DO-214AA package enables compact layout, and its −55 to +150 °C operating range accommodates internal enclosure temperatures in sealed TV chassis.
How does the glass passivation in HS3GB R5G improve reliability?
The glass passivation layer on the HS3GB R5G's silicon junction provides hermetic protection against moisture ingress, ionic contamination, and mechanical stress during thermal cycling. As documented in the Features list, this structure enhances long-term parameter stability-particularly reverse leakage (IR) and breakdown voltage-under humid, high-temperature conditions typical in consumer electronics deployed in tropical or enclosed environments.
