Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAS40-06LT1 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Diode Configuration: 1 Pair Common Anode (pin-compatible)
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 40 V (minimum requirement)
• Current - Average Rectified (Io) (per Diode): Equal to or greater than 120 mA
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 40 mA (maximum)

Mechanical Compatibility Requirements:

• Package / Case: TO-236-3, SC-59, SOT-23-3
• Mounting Type: Surface Mount

Compliance Requirements:

• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected
• ECCN: EAR99

All substitute parts listed maintain these critical parameters, ensuring direct functional and physical interchangeability with the obsolete BAS40-06LT1.

Parameter Comparison

Engineering Selection Recommendations

BAS40-06LT1G (onsemi)

This part is the direct equivalent from the original manufacturer. It maintains identical electrical specifications (40 V, 120 mA per diode) and package configuration. The BAS40-06LT1G is classified as active with ROHS3 compliance, providing long-term availability and regulatory alignment. This is the primary substitution choice for applications requiring manufacturer continuity.

BAS40-06-E3-08 (Vishay General Semiconductor - Diodes Division)

This part provides enhanced current capability at 200 mA per diode while maintaining the 40 V reverse voltage rating and identical forward voltage characteristics. The higher current rating ensures compatibility with applications operating at or below the original 120 mA specification. ROHS3 compliance and active product status support ongoing procurement. This option is suitable for designs where current margin is beneficial.

BAS40-06-TP (Micro Commercial Co)

This part also provides 200 mA per diode current rating with 40 V reverse voltage and matching forward voltage specifications. Active product status and ROHS3 compliance ensure availability and regulatory compliance. The higher current rating provides operational margin equivalent to the Vishay option. This alternative offers broad inventory availability.

All three substitute parts are electrically and mechanically compatible with the BAS40-06LT1, with the primary distinction being current rating (120 mA vs. 200 mA) and manufacturer source. Selection should be based on procurement strategy, inventory availability, and design margin requirements.

Frequently Asked Questions (FAQ)

Q: Can BAS40-06LT1G be used as a direct replacement for BAS40-06LT1?

A: Yes. The BAS40-06LT1G maintains identical electrical specifications (40 V reverse voltage, 120 mA average rectified current per diode, 1 V forward voltage at 40 mA) and package configuration (SOT-23-3 surface mount). Pin configuration and functional behavior are equivalent.

Q: What is the difference between the 120 mA and 200 mA current ratings?

A: The BAS40-06LT1 and BAS40-06LT1G are rated for 120 mA average rectified current per diode. The BAS40-06-E3-08 and BAS40-06-TP are rated for 200 mA. All parts are compatible with applications operating at or below 120 mA. The higher-rated parts provide additional current margin without affecting forward voltage or reverse voltage characteristics.

Q: Are all substitute parts RoHS compliant?

A: The BAS40-06LT1 is RoHS non-compliant. All three substitute parts (BAS40-06LT1G, BAS40-06-E3-08, BAS40-06-TP) are ROHS3 compliant, meeting current regulatory requirements for new designs and production.

Q: Do the substitute parts have the same package dimensions?

A: Yes. All substitute parts use the TO-236-3, SC-59, SOT-23-3 package designation, which specifies identical physical dimensions and pin configuration. Surface mount placement and soldering procedures remain unchanged.

Q: What is the Moisture Sensitivity Level for these parts?

A: All parts, including the main part and substitutes, have Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.

Q: Are there any differences in operating temperature range?

A: The BAS40-06LT1 operating temperature range is not specified in the provided data. The BAS40-06LT1G operates from -55°C to 150°C. The BAS40-06-E3-08 has a maximum junction temperature of 125°C. The BAS40-06-TP operates from -55°C to 125°C. These ranges are suitable for standard industrial and commercial applications.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, within the electrical and mechanical parameters specified. All substitute parts maintain the 40 V reverse voltage rating, SOT-23-3 package, and 1 Pair Common Anode configuration. Designs operating at or below 120 mA per diode current will function identically with any of the listed substitutes.
