Product details
Overview
S3GBH from Taiwan Semiconductor is a surface-mount silicon rectifier diode rated for 3A average forward current and 400V repetitive peak reverse voltage in a DO-214AA (SMB) package, featuring low forward voltage drop (max 1.15V at 3A, 25°C), high surge capability (80A IFSM), and AEC-Q101 qualification for automotive use.
For engineers reviewing the S3GBH datasheet, S3GBH pinout, S3GBH application, or S3GBH equivalent, key selection considerations include its 400V VRRM rating, 1500ns reverse recovery time, glass-passivated junction, moisture sensitivity level 1 compliance, and suitability for freewheeling and snubber circuits in DC-DC converters and automotive lighting systems.
Technical Context
The S3GBH is a single-die, standard recovery rectifier with a PN junction structure optimized for general-purpose switching and energy recovery. Its 1500ns trr and 40pF junction capacitance reflect trade-offs between switching speed and forward conduction loss.
Thermally, it delivers 10°C/W junction-to-lead resistance and operates across –55°C to +150°C junction temperature range. The device uses matte tin-plated leads compliant with J-STD-002 solderability and meets JESD201 Class 2 whisker resistance.
Key Specifications

Use Value: Glass passivation ensures stable IR over time; DO-214AA footprint allows compact layout near power FETs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L04S | 400V VRRM, 3A IF, 75ns trr, TO-277 package | Ultrafast recovery enables higher-frequency operation but higher VF (~1.3V) | Prefer when switching frequency >50kHz; avoid if conduction loss dominates thermal budget |
| SB340-E3/52T | 40V VRRM, 3A IF, Schottky, DO-214AA | Lower VF (~0.55V) but limited to 40V systems; no reverse recovery | Only suitable for low-voltage DC-DC outputs; not interchangeable for 400V blocking needs |
Compared with STTH3L04S and SB340-E3/52T, the S3GBH offers optimal balance of 400V blocking, 3A current handling, and cost-effective standard recovery performance-ideal where moderate trr and low VF are jointly required in automotive and industrial power supplies.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) rating for the S3GBH?
The S3GBH has a VRRM rating of 400 V, meaning it can reliably block reverse voltages up to this level without breakdown under repetitive conditions. This value is fixed for the S3GBH variant within the S3ABH–S3MBH family and is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version B2207). Exceeding 400 V risks irreversible avalanche failure.
Is the S3GBH suitable for automotive applications?
Yes, the S3GBH is AEC-Q101 qualified and explicitly listed for automotive applications including car lighting and DC–DC converters. Its construction features glass-passivated junctions, moisture sensitivity level 1, and operation from –55°C to +150°C, meeting core automotive reliability requirements. The S3GBH datasheet confirms qualification status and thermal performance validated per AEC stress test protocols.
What package type does the S3GBH use, and what are its key mechanical attributes?
The S3GBH uses the DO-214AA (SMB) surface-mount package, with matte tin-plated leads compliant with J-STD-002, UL 94V-0 molding compound, and polarity indicated by a cathode band. Its weight is approximately 0.090 g. The S3GBH footprint matches industry-standard SMB land patterns, supporting automated placement and reflow soldering without pre-baking due to its MSL Level 1 rating.
What is the reverse recovery time (trr) of the S3GBH, and how does it affect circuit design?
The S3GBH has a reverse recovery time (trr) of 1500 ns under specified test conditions (IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A). This standard recovery characteristic makes the S3GBH appropriate for line-frequency and low-to-moderate switching frequency applications (e.g., <100 kHz), but not for high-frequency SMPS where ultrafast or Schottky alternatives would reduce switching losses. Designers must account for trr-induced turn-off losses in thermal calculations.
Does the S3GBH have RoHS and halogen-free compliance?
Yes, the S3GBH is RoHS compliant and halogen-free per IEC 61249-2-21, as stated in the official Taiwan Semiconductor documentation. These compliance statements apply specifically to the S3GBH and all variants in the S3ABH–S3MBH family. The halogen-free status ensures reduced toxic gas emission during PCB assembly and end-of-life disposal, aligning with stringent environmental requirements in automotive and industrial markets.
