Engineering Selection Recommendations

The BAS20-E3-18 is a parametric equivalent to the BAS20-G3-08. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and share identical electrical specifications and mechanical packaging. Both components maintain Active product status and are ROHS3 compliant, meeting current regulatory requirements. The BAS20-E3-18 is available in higher inventory quantity (7657 Pcs) compared to the BAS20-G3-08 (1002 Pcs), which may provide supply chain advantages. Selection between these parts is based on availability, lead time, and packaging tape configuration (G3-08 versus E3-18 denote different tape specifications). Both parts are suitable for applications requiring 150 V reverse voltage, 200 mA rectified current, and SOT-23-3 surface mount packaging.

Frequently Asked Questions (FAQ)

Q: Can the BAS20-E3-18 be used as a direct replacement for the BAS20-G3-08?

A: Yes. The BAS20-E3-18 is a parametric equivalent with identical electrical characteristics, including reverse voltage rating, forward voltage drop, reverse recovery time, leakage current, and capacitance. Both components use the same SOT-23-3 package and operate across the same temperature range. The difference between part numbers reflects tape reel configuration only.

Q: What is the significance of the G3-08 and E3-18 designations?

A: These designations identify different tape and reel specifications for the same diode. The suffix indicates the packaging configuration used for automated assembly. The electrical and mechanical performance of the diode itself remains identical.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both the BAS20-G3-08 and BAS20-E3-18 are ROHS3 compliant, REACH unaffected, and carry the same ECCN and HTSUS classifications. Both maintain Active product status with Moisture Sensitivity Level 1 (Unlimited).

Q: What are the critical parameters for substitution in rectifier diode applications?

A: The critical parameters are reverse voltage rating (150 V), average rectified current (200 mA), forward voltage drop (1.25 V @ 200 mA), reverse recovery time (50 ns), reverse leakage current (100 nA @ 150 V), and package type (SOT-23-3). All these parameters must match for direct substitution.

Q: Can these diodes be used in high-frequency switching applications?

A: These are classified as small signal diodes with a reverse recovery time of 50 ns. Applications requiring faster switching or different recovery characteristics require evaluation of alternative diode types.

Q: What is the operating temperature range for these components?

A: The junction operating temperature range is -55°C to 150°C for both the BAS20-G3-08 and BAS20-E3-18.
