Taiwan Semiconductor Corporation HS3B M6G

Overview

HS3B M6G from Taiwan Semiconductor is a 100 V, 3 A surface-mount high-efficiency rectifier diode in DO-214AB (SMC) package, featuring 150 A surge rating, 1.0 V forward voltage at 3 A/25°C, and 80 pF junction capacitance - used in freewheeling paths and SMPS secondary-side rectification in telecom power supplies.

For engineers reviewing the HS3B M6G datasheet, HS3B M6G pinout, HS3B M6G application, or HS3B M6G equivalent, key selection criteria include repetitive peak reverse voltage (100 V), thermal resistance (60 °C/W), moisture sensitivity level (J-STD-020 Level 1), RoHS/halogen-free compliance, and SMC package compatibility with automated placement.

Technical Context

This single-die silicon rectifier uses glass-passivated junction technology to achieve low forward voltage drop and stable reverse leakage (<10 µA at 25°C, <250 µA at 125°C). Its 50 ns reverse recovery time supports high-frequency switching up to several hundred kHz in DC-DC converters.

The DO-214AB (SMC) package provides robust thermal performance (R_θJA = 60 °C/W) and mechanical reliability, with matte tin-plated leads compliant to J-STD-002 solderability and JESD 201 Class 2 whisker resistance.

FAQ

What is the maximum junction temperature rating for HS3B M6G?

The HS3B M6G has a maximum junction temperature (T_J) rating of +150 °C, enabling operation in thermally demanding environments such as enclosed telecom power supplies. This rating must be respected in thermal design - derating curves show usable I_F drops to ~1.8 A at 100 °C ambient with standard PCB copper. The HS3B M6G's 60 °C/W junction-to-ambient thermal resistance guides heatsinking requirements.

Is HS3B M6G suitable for high-frequency switching applications like 300 kHz flyback converters?

Yes, HS3B M6G is qualified for high-frequency rectification up to 500 kHz due to its 50 ns reverse recovery time (t_rr) and 80 pF junction capacitance. These parameters minimize switching losses and EMI generation in flyback and forward converters. The HS3B M6G's glass-passivated junction also ensures stable t_rr across temperature - critical for consistent performance in 300 kHz telecom SMPS.

Does HS3B M6G meet RoHS and halogen-free requirements?

Yes, HS3B M6G is fully RoHS compliant per EU Directive 2011/65/EU and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants, and the matte tin-plated leads satisfy J-STD-002 solderability standards. These certifications are verified in TSC's K2102 datasheet revision and apply directly to the HS3B M6G marking variant.

What does the "M6G" suffix indicate in HS3B M6G?

The "M6G" suffix in HS3B M6G denotes Taiwan Semiconductor's internal date code and factory identifier: "M6" indicates manufacturing week/year (e.g., 2026 Week 6), and "G" identifies the fabrication site. It does not affect electrical specifications - all HS3B devices share identical V_RRM = 100 V, I_F = 3 A, and thermal characteristics regardless of suffix. HS3B M6G remains functionally interchangeable with other HS3B date codes.

Can HS3B M6G replace HS3A or HS3D in an existing design?

No - HS3B M6G is not a drop-in replacement for HS3A (50 V) or HS3D (200 V) due to different V_RRM ratings. Substituting HS3B M6G into a circuit designed for HS3A risks overvoltage failure; using it where HS3D is specified may compromise safety margin. Always verify reverse voltage stress margins before interchanging within the HS3x family. HS3B M6G is only functionally equivalent to other HS3B-marked devices.
