Product details
Overview
S5B V7G from Taiwan Semiconductor is a 5A, 100V surface-mount general-purpose rectifier diode in DO-214AB (SMC) package, featuring glass-passivated junction, low forward voltage drop (max 1.15V at 5A), high surge current capability (100A), and RoHS/halogen-free compliance. It serves as the primary output rectifier in AC/DC adapters and offline SMPS.
For engineers reviewing the S5B V7G datasheet, S5B V7G pinout, S5B V7G application, or S5B V7G equivalent, key selection criteria include repetitive peak reverse voltage (100V), forward current rating (5A), thermal resistance (RθJL = 13°C/W), reverse recovery time (1500 ns), and moisture sensitivity level (MSL 1).
Technical Context
The S5B V7G is a single-die, standard-recovery silicon rectifier optimized for cost-sensitive, medium-frequency switching applications up to ~100 kHz. Its 1500 ns reverse recovery time and 60 pF junction capacitance reflect trade-offs between switching loss and conduction efficiency in flyback and forward converter topologies.
Designed for surface-mount assembly with matte tin-plated leads compliant to J-STD-002, the device operates across -55°C to +150°C junction temperature range and meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH5L06 (STMicroelectronics) | 600 V VRRM, 1.7 V VF (max), faster trr = 75 ns | Higher voltage, higher VF, ultrafast recovery - suited for PFC stages or higher-frequency designs | Select when >100 V blocking or <200 ns trr required; not drop-in due to VF and thermal profile mismatch |
| MBR5100CT (ON Semiconductor) | 100 V VRRM, 5 A per diode, dual common-cathode Schottky, VF = 0.85 V (typ) | Lower VF, no reverse recovery - reduces switching loss but limited to ≤150°C operation | Choose for efficiency-critical 100 V applications below 125°C ambient; requires layout verification for dual-diode footprint |
Compared with STTH5L06 and MBR5100CT, the S5B V7G offers lower cost, MSL 1 handling, and proven robustness in 100 V adapter applications-but trades off speed and forward voltage for ruggedness and thermal margin.

FAQ
What is the maximum junction temperature rating for the S5B V7G?
The S5B V7G has a maximum junction temperature (TJMAX) of +150°C, enabling operation in thermally demanding environments such as enclosed LED drivers or high-ambient industrial power supplies. This rating is validated per absolute maximum ratings table in the official Taiwan Semiconductor datasheet F2102. Derating curves must be applied above 75°C ambient to maintain reliability.
Is the S5B V7G RoHS and halogen-free compliant?
Yes, the S5B V7G is RoHS compliant and halogen-free per IEC 61249-2-21. This is confirmed in the "Features" section of the Taiwan Semiconductor S5A–S5M datasheet (Version F2102). The device uses matte tin-plated leads and UL 94V-0 molding compound, meeting environmental and safety requirements for global electronics manufacturing.
What does the 'V7G' suffix in S5B V7G indicate?
The 'V7G' suffix in S5B V7G denotes Taiwan Semiconductor's internal date code and factory marking: 'V7' indicates week 7 of year 2025, and 'G' identifies the fabrication facility. This matches the marking diagram in the S5A–S5M datasheet (Version F2102), where 'F' = factory, 'YW' = date code, and 'G' = green compound. The core electrical specs remain identical to S5B.
Can the S5B V7G replace the S5B in existing designs?
Yes, the S5B V7G is a direct form-fit-function replacement for the base S5B part. Both share identical DO-214AB (SMC) package, pinout, absolute maximum ratings, and electrical specifications per the F2102 datasheet. The 'V7G' suffix reflects updated traceability coding-not a functional revision-so no layout or validation changes are needed.
What is the reverse recovery time (trr) of the S5B V7G and how is it measured?
The S5B V7G has a reverse recovery time (trr) of 1500 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, per the Electrical Specifications table in the F2102 datasheet. This value reflects its standard-recovery behavior and is critical for estimating switching losses in 50–100 kHz SMPS designs using the S5B V7G.
