Parameter Comparison

Engineering Selection Recommendations

BAS40-05 RFG (Taiwan Semiconductor Corporation)

This part is a parametric equivalent with identical electrical specifications to the BAS40-05HE3-TP. It is currently active in production with 6799 units in stock. The operating temperature range extends to -65°C minimum, providing broader low-temperature performance. This part is suitable for applications where the main part is unavailable and non-automotive qualification is acceptable. RoHS3 compliance and MSL-1 rating are maintained.

BAS40-05-G3-08 (Vishay General Semiconductor - Diodes Division)

This part meets all core electrical and mechanical specifications with improved reverse leakage characteristics (100 nA @ 30 V versus 200 nA @ 30 V). It is currently active with the highest inventory availability at 15644 units. This part is suitable for general-purpose applications where automotive qualification is not required. RoHS3 compliance and MSL-1 rating are maintained.

BAS40-05-HE3-08 (Vishay General Semiconductor - Diodes Division)

This part is electrically and mechanically equivalent to the BAS40-05HE3-TP with identical automotive grade and AEC-Q101 qualification. However, this part is marked as obsolete in the current product status. It maintains 26300 units in inventory. This part is suitable only for applications where existing stock is available and long-term supply is not required. Use of this part should be limited to legacy designs or short-term production runs.

CMPSH-3CE TR PBFREE (Central Semiconductor Corp)

This part is a parametric equivalent with identical core specifications. It features an extended operating temperature range to 150°C maximum and improved low-temperature performance to -65°C minimum. Forward voltage is specified at 200 mA (full rated current) rather than 40 mA. Reverse leakage is higher at 500 nA @ 25 V. This part is currently active with 29081 units in stock. It is suitable for applications requiring extended temperature performance where automotive qualification is not required. RoHS3 compliance and MSL-1 rating are maintained.

Frequently Asked Questions (FAQ)

Q: Can BAS40-05 RFG be used as a direct replacement for BAS40-05HE3-TP?

A: Yes. BAS40-05 RFG meets all mandatory equivalence parameters: 40 V reverse voltage, 200 mA average rectified current, 5 ns reverse recovery time, SOT-23-3 package, and ROHS3 compliance. The extended operating temperature range (-65°C to 125°C) provides additional margin. This part is suitable for non-automotive applications.

Q: What is the difference between BAS40-05-G3-08 and BAS40-05-HE3-08?

A: Both parts are electrically equivalent with identical 40 V, 200 mA specifications and SOT-23-3 packaging. BAS40-05-HE3-08 carries automotive grade and AEC-Q101 qualification, matching the main part BAS40-05HE3-TP. However, BAS40-05-HE3-08 is marked obsolete. BAS40-05-G3-08 is currently active but lacks automotive qualification. Selection depends on qualification requirements and supply continuity needs.

Q: Is CMPSH-3CE TR PBFREE compatible with the BAS40-05HE3-TP in all applications?

A: CMPSH-3CE TR PBFREE is mechanically and electrically compatible for circuit-level substitution. All core parameters match: 40 V reverse voltage, 200 mA current, 5 ns recovery time, and SOT-23-3 package. However, reverse leakage is higher (500 nA @ 25 V versus 200 nA @ 30 V), and automotive qualification is not included. Applications sensitive to leakage current or requiring AEC-Q101 certification should use BAS40-05HE3-TP or BAS40-05-HE3-08.

Q: Can these parts be used interchangeably in automotive applications?

A: Only BAS40-05HE3-TP and BAS40-05-HE3-08 carry automotive grade and AEC-Q101 qualification. BAS40-05 RFG, BAS40-05-G3-08, and CMPSH-3CE TR PBFREE lack automotive certification and are not qualified for automotive applications. Use of non-qualified parts in automotive designs requires design review and qualification assessment.

Q: What is the impact of different reverse leakage specifications?

A: Reverse leakage varies across the substitute parts: 100 nA (BAS40-05-G3-08, BAS40-05-HE3-08), 200 nA (BAS40-05HE3-TP, BAS40-05 RFG), and 500 nA (CMPSH-3CE TR PBFREE). Higher leakage increases standby current and power dissipation in low-current applications. Applications with strict leakage requirements should use parts with lower leakage specifications.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All substitute parts listed are supplied in Tape & Reel (TR) packaging suitable for automated assembly. All parts maintain MSL-1 (Unlimited) moisture sensitivity level, requiring no special storage or handling precautions.

Q: What is the minimum operating temperature difference between parts?

A: BAS40-05HE3-TP operates from -55°C minimum. BAS40-05 RFG and CMPSH-3CE TR PBFREE extend to -65°C minimum, providing 10°C additional margin. BAS40-05-G3-08 and BAS40-05-HE3-08 do not specify a minimum temperature. For applications requiring operation below -55°C, use BAS40-05 RFG or CMPSH-3CE TR PBFREE.

Q: Which substitute part has the highest inventory availability?

A: CMPSH-3CE TR PBFREE has the highest inventory at 29081 units, followed by BAS40-05-HE3-08 at 26300 units. For supply chain continuity, CMPSH-3CE TR PBFREE offers the largest available stock, though it lacks automotive qualification.
