Product details
Overview
HS3B V6G from Taiwan Semiconductor is a 3A, 100V high-efficiency surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring 1.0V max forward voltage at 3A/25°C, 150A peak surge current, and 50ns reverse recovery time. It serves as a primary output rectifier in AC-DC adapters and freewheeling diode in buck converters for telecom power supplies.
For engineers reviewing the HS3B V6G datasheet, HS3B V6G pinout, HS3B V6G application, or HS3B V6G equivalent, key selection criteria include repetitive peak reverse voltage (100V), thermal resistance (60°C/W), junction capacitance (80pF), moisture sensitivity level (MSL 1), and RoHS/halogen-free compliance per IEC 61249-2-21.
Technical Context
This device is a single-die, glass-passivated, planar-junction silicon rectifier optimized for high-frequency switching applications. Its low-profile DO-214AB package supports automated placement and meets UL 94V-0 flammability rating with matte tin-plated leads compliant to J-STD-002 solderability.
The HS3B V6G operates across -55°C to +150°C junction temperature range and exhibits 10µA max reverse leakage at 25°C and rated VR. Its 50ns trr enables efficient operation in SMPS topologies up to several hundred kHz without significant switching loss penalties.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600V VRRM, 1.7V VF @ 3A, 75ns trr, TO-277 package | Higher voltage rating but higher VF and slower recovery; larger footprint | Select when >100V reverse margin required; not drop-in due to different package and pinout |
| MBR3100CT | Dual common-cathode Schottky, 100V, 1.2V VF, 120°C TJ max, TO-220AC | Lower VF but higher leakage and limited to 125°C; through-hole mounting | Choose for lower conduction loss where thermal management permits TO-220; requires PCB redesign |
Compared with STTH3L06S and MBR3100CT, the HS3B V6G delivers optimal balance of low VF (1.0V), fast trr (50ns), and compact SMC packaging for space-constrained 100V-class SMPS-without sacrificing MSL 1 process compatibility or halogen-free compliance.

FAQ
What is the maximum junction temperature rating for HS3B V6G?
The HS3B V6G has a maximum junction temperature (TJ MAX) of +150°C, allowing continuous operation in high-ambient environments such as enclosed industrial power supplies. This rating is validated per JEDEC standards and supported by its 60°C/W junction-to-ambient thermal resistance. Derating begins above 25°C ambient per the forward current derating curve in the HS3B V6G datasheet.
Does HS3B V6G support lead-free reflow soldering?
Yes, the HS3B V6G features matte tin-plated leads qualified to J-STD-002 for solderability and is fully compatible with standard lead-free reflow profiles (peak 260°C). Its MSL Level 1 rating means it can be stored indefinitely at ≤30°C/60% RH without baking prior to assembly-no special handling required for the HS3B V6G.
What is the reverse leakage current specification for HS3B V6G at elevated temperature?
At 125°C junction temperature and rated reverse voltage (100V), the HS3B V6G exhibits a maximum reverse leakage current (IR) of 250 µA, per pulse-tested conditions (PW = 30ms). This value is critical for standby power budgeting in energy-efficient designs and remains well within limits for Class VI-compliant AC-DC adapters using the HS3B V6G.
Is HS3B V6G pin-compatible with other devices in the HS3x family?
Yes, all HS3x devices-including HS3A, HS3B, HS3D through HS3M-share identical DO-214AB (SMC) package dimensions, pinout, and thermal characteristics. The only differences are VRRM rating and corresponding VF/trr/CJ values; thus, HS3B V6G can be substituted within the same footprint when 100V blocking is sufficient, without PCB changes.
How does the 50ns reverse recovery time of HS3B V6G impact EMI in high-frequency converters?
The 50ns trr of HS3B V6G reduces reverse recovery charge (Qrr) and associated di/dt-induced voltage spikes, directly lowering high-frequency conducted EMI in 300–500kHz flyback or resonant converters. This enables simpler EMI filter design and helps meet CISPR-32 Class B limits without additional snubbers-confirmed in reference designs using the HS3B V6G.
