Parameter Comparison

Engineering Selection Recommendations

BAS20WTHE3-TP (Micro Commercial Co): This substitute part is parametrically equivalent to the BAS20WT-TP with identical electrical specifications and package configuration. The BAS20WTHE3-TP carries AEC-Q101 automotive qualification, indicating compliance with automotive-grade reliability standards. Selection of this part is appropriate for applications requiring automotive-grade components or when higher inventory availability is a consideration (5880 pcs in stock versus 977 pcs for the primary part).

BAS20W-7-F (Diodes Incorporated): This substitute part is manufactured by Diodes Incorporated and maintains all critical electrical parameters identical to the BAS20WT-TP. The operating temperature range extends to -65°C minimum (compared to -55°C for the primary part), providing enhanced low-temperature performance. This part is suitable for applications requiring extended temperature operation or when sourcing from alternative manufacturers is necessary. Inventory availability is 8600 pcs.

Both substitute parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are actively produced. Selection between the primary part and substitutes is determined by supply availability, manufacturer preference, automotive qualification requirements, or extended temperature range needs.

Frequently Asked Questions (FAQ)

Q: Can BAS20WTHE3-TP be used as a direct replacement for BAS20WT-TP?

A: Yes. The BAS20WTHE3-TP is parametrically equivalent to the BAS20WT-TP. All electrical specifications including reverse voltage, forward current, forward voltage drop, reverse recovery time, reverse leakage current, and junction capacitance are identical. Both components use the same SOT-323 package and surface mount configuration. The primary difference is the automotive-grade AEC-Q101 qualification of the BAS20WTHE3-TP.

Q: Can BAS20W-7-F be used as a direct replacement for BAS20WT-TP?

A: Yes. The BAS20W-7-F is parametrically equivalent to the BAS20WT-TP across all critical electrical specifications. Both components are rated for 150V reverse voltage, 200mA average rectified current, 1.25V forward voltage drop at 200mA, 50ns reverse recovery time, and identical junction capacitance. Both use the SOT-323 package. The BAS20W-7-F is manufactured by Diodes Incorporated and features an extended minimum operating temperature of -65°C compared to -55°C for the BAS20WT-TP.

Q: What are the key parameters that determine substitutability for the BAS20WT-TP?

A: Substitutability is determined by matching the following parameters: Voltage - DC Reverse (Vr) (Max) of 150V, Current - Average Rectified (Io) of 200mA, Voltage - Forward (Vf) (Max) of 1.25V at 200mA, Reverse Recovery Time (trr) of 50ns, Current - Reverse Leakage of 100nA at 150V, Capacitance of 5pF at 0V and 1MHz, SOT-323 package configuration, surface mount mounting type, ROHS3 compliance, and MSL 1 rating.

Q: Are there any temperature range differences between the substitute parts and the primary part?

A: The BAS20WT-TP and BAS20WTHE3-TP both operate from -55°C to 150°C junction temperature. The BAS20W-7-F extends the minimum operating temperature to -65°C, providing a 10°C wider low-temperature range. The maximum junction temperature of 150°C is identical across all three parts.

Q: Do all three parts carry the same compliance certifications?

A: All three parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. The BAS20WTHE3-TP additionally carries AEC-Q101 automotive qualification, which is not specified for the BAS20WT-TP or BAS20W-7-F. All parts are actively produced and REACH unaffected.

Q: What is the difference between the BAS20WT-TP and BAS20WTHE3-TP beyond automotive qualification?

A: The electrical specifications and package configuration are identical between these two parts. The BAS20WTHE3-TP is qualified to AEC-Q101 automotive standards, indicating it has undergone additional reliability testing and qualification procedures required for automotive applications. Both parts are manufactured by Micro Commercial Co and maintain the same performance characteristics.

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

A: Yes. All three parts share identical reverse recovery time (trr) of 50ns and junction capacitance of 5pF at 0V and 1MHz, which are the critical parameters for high-frequency switching performance. The parts are classified as small signal diodes with switching speeds suitable for applications up to 200mA.
