BAT40VC-7 Equivalent & Substitute Parts

Part Overview

The BAT40VC-7 is a Schottky diode array featuring 2 independent diodes rated for 40 V DC reverse voltage and 200 mA average rectified current per diode. The device is packaged in SOT-563 and SOT-666 surface mount configurations. The BAT40VC-7 is classified as obsolete product status, necessitating identification of active equivalent alternatives for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAT40VC-7 is determined by electrical and mechanical parameter equivalence within the Schottky diode rectifier category. The following parameters establish substitution validity:

Critical Matching Parameters:

• Diode Configuration: 2 Independent
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 40 V
• Current - Average Rectified (Io) (per Diode): 200 mA (DC)
• Reverse Recovery Time (trr): 5 ns
• Package / Case: SOT-563, SOT-666
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Substitute parts BAT40V-7 and BAS40V-7 maintain electrical equivalence across these critical parameters. Variations in forward voltage characteristics and reverse leakage current at different test conditions do not preclude substitution within the specified operating envelope.

Engineering Selection Recommendations

BAT40V-7 (Primary Substitute)

The BAT40V-7 is the preferred substitute for the obsolete BAT40VC-7. Both parts share identical electrical specifications including forward voltage characteristics (1 V @ 200 mA), reverse recovery time (5 ns), and operating temperature range (-65°C ~ 125°C). The BAT40V-7 maintains active product status with significantly higher inventory availability (227,400 pcs). Packaging, mounting type, and compliance certifications (ROHS3, REACH Unaffected) are identical. This part provides direct functional replacement without design modification.

BAS40V-7 (Secondary Substitute)

The BAS40V-7 is an alternative substitute with active product status. It maintains equivalence across critical electrical parameters: 40 V reverse voltage, 200 mA average rectified current, 5 ns reverse recovery time, and identical package/mounting specifications. The BAS40V-7 operates within a narrower temperature range (-55°C ~ 125°C) compared to the BAT40VC-7 (-65°C ~ 125°C). Forward voltage is specified at 1 V @ 40 mA rather than @ 200 mA. Selection of BAS40V-7 is appropriate for applications where the reduced lower temperature limit and alternative forward voltage test condition do not conflict with system requirements.

Frequently Asked Questions (FAQ)

Q: Can BAT40V-7 be used as a direct replacement for BAT40VC-7?

A: Yes. The BAT40V-7 provides direct functional equivalence. Both parts feature identical diode configuration (2 independent), technology (Schottky), reverse voltage rating (40 V), average rectified current (200 mA), forward voltage (1 V @ 200 mA), reverse recovery time (5 ns), operating temperature range (-65°C ~ 125°C), and package specifications (SOT-563, SOT-666). The BAT40V-7 is active product status, addressing the obsolescence of the BAT40VC-7.

Q: What are the differences between BAT40V-7 and BAS40V-7?

A: Both parts are functionally equivalent for the critical electrical parameters. The primary differences are: (1) Operating temperature range: BAT40V-7 operates from -65°C to 125°C, while BAS40V-7 operates from -55°C to 125°C; (2) Forward voltage test condition: BAT40V-7 is specified at 1 V @ 200 mA, while BAS40V-7 is specified at 1 V @ 40 mA. These differences do not affect substitution validity for applications within the BAS40V-7 temperature range.

Q: Are the packaging and mounting specifications identical across all three parts?

A: Yes. BAT40VC-7, BAT40V-7, and BAS40V-7 all use SOT-563 and SOT-666 package cases with surface mount mounting type. Supplier device package is SOT-563 for all three parts. No PCB layout or assembly process modifications are required when substituting between these parts.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. BAT40VC-7, BAT40V-7, and BAS40V-7 are all ROHS3 compliant, REACH unaffected, and classified as Moisture Sensitivity Level 1 (Unlimited). Compliance certifications are equivalent across all three parts.

Q: Which substitute should be selected for new designs?

A: BAT40V-7 is the recommended selection for new designs. It provides complete electrical and mechanical equivalence to the BAT40VC-7 with active product status and superior inventory availability. BAS40V-7 is suitable as an alternative when the narrower operating temperature range (-55°C ~ 125°C) is acceptable for the application.
