Taiwan Semiconductor Corporation S3BHM6G

Overview

S3BHM6G from Taiwan Semiconductor is a surface-mount silicon rectifier diode with 100 V repetitive peak reverse voltage (V_RRM), 3 A average forward current (I_F), and 100 A non-repetitive surge capability (I_FSM), housed in a DO-214AB (SMC) package; it delivers low forward voltage drop (≤1.15 V at 3 A, 25°C) and is used in AC/DC front-end rectification for switching mode power supplies and LED lighting drivers.

For engineers reviewing the S3BHM6G datasheet, S3BHM6G pinout, S3BHM6G application, or S3BHM6G equivalent, key selection criteria include V_RRM rating, thermal resistance (R_θJL = 13 °C/W), moisture sensitivity level (MSL 1), junction capacitance (60 pF), and reverse recovery time (1500 ns) - all critical for high-efficiency, high-reliability rectifier design in compact industrial and consumer power converters.

Technical Context

This device is a single-die, glass-passivated, standard recovery silicon rectifier optimized for cost-sensitive, medium-power AC/DC conversion where fast recovery is not required but robust surge handling and thermal performance are essential. Its DO-214AB package supports automated placement and provides reliable lead-to-lead isolation under 100 V reverse bias.

The S3BHM6G operates across –55°C to +150°C junction temperature range, exhibits ≤10 µA reverse leakage at 25°C and rated V_R, and maintains stable forward conduction with typical VF of 1.15 V at full-rated 3 A load - enabling predictable thermal modeling in board-level power stage layouts.

FAQ

What is the maximum junction temperature rating for the S3BHM6G?

The S3BHM6G has a maximum junction temperature (T_J) of +150°C and a minimum of –55°C, allowing operation in harsh ambient environments such as enclosed LED drivers or industrial control cabinets. This rating is validated under specified thermal conditions and must be maintained via appropriate PCB copper area and airflow per the R_θJL = 13 °C/W specification. Thermal design for the S3BHM6G should always reference its absolute maximum ratings table in the official Taiwan Semiconductor datasheet.

Does the S3BHM6G have a halogen-free and RoHS-compliant construction?

Yes, the S3BHM6G is both halogen-free and RoHS compliant, as confirmed in Taiwan Semiconductor's official documentation. The molding compound contains no brominated flame retardants, and lead content is below 1000 ppm. These attributes meet EU Directive 2011/65/EU and IPC-1752 requirements, supporting environmentally responsible manufacturing and end-of-life recycling for products using the S3BHM6G.

What is the reverse recovery time (t_rr) of the S3BHM6G and how does it affect circuit performance?

The S3BHM6G has a reverse recovery time (t_rr) of 1500 ns under standard test conditions (I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A). This relatively long t_rr indicates standard recovery behavior, making it unsuitable for high-frequency (>200 kHz) hard-switched topologies but well-suited for lower-frequency flyback, forward, or LLC converters where conduction loss dominates. Designers using the S3BHM6G should verify snubber sizing and EMI filtering accordingly.

Is the S3BHM6G suitable for use in automotive applications?

The S3BHM6G is not qualified to AEC-Q101 or automotive-grade reliability standards and is not recommended for safety-critical automotive systems. While its –55°C to +150°C operating range overlaps with some automotive ambient conditions, Taiwan Semiconductor explicitly states that the S3x series is not designed for medical, life-saving, or life-sustaining applications - including automotive powertrain or ADAS subsystems. For such uses, consult AEC-Q101-certified alternatives.

What is the moisture sensitivity level (MSL) and reflow profile guidance for the S3BHM6G?

The S3BHM6G is rated MSL Level 1 per J-STD-020, meaning it is not moisture sensitive and can be stored indefinitely at ambient conditions without dry packing or baking prior to reflow soldering. Standard Pb-free reflow profiles apply, with peak temperature ≤260°C and time above 217°C limited to 60–150 seconds. The device's matte tin-plated leads comply with J-STD-002 for solderability, ensuring robust joint formation in automated SMT lines.
