BAS16TW-7 Equivalent & Substitute Parts

Part Overview

The BAS16TW-7 is a diode array containing three independent general-purpose rectifier diodes rated for 75 V DC reverse voltage and 150 mA average rectified current per diode. The device is packaged in a 6-TSSOP (SC-88, SOT-363) surface mount configuration and operates across a junction temperature range of -65°C to 150°C.

The BAS16TW-7 is currently discontinued at DiGi Electronics, with 3,300 pieces available as new original stock. Identification of equivalent and substitute parts is necessary to ensure continued design support, maintain supply chain flexibility, and accommodate alternative sourcing requirements for new production runs or design revisions.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAS16TW-7 is determined by the following critical parameters:

Electrical Parameters:

• Voltage - DC Reverse (Vr) (Max): 75 V minimum
• Current - Average Rectified (Io) (per Diode): 150 mA minimum
• Voltage - Forward (Vf) (Max) @ If: 1.25 V @ 150 mA maximum
• Reverse Recovery Time (trr): 4 ns maximum
• Diode Configuration: 3 Independent

Mechanical Parameters:

• Package / Case: 6-TSSOP, SC-88, SOT-363
• Mounting Type: Surface Mount

Environmental Parameters:

• Operating Temperature - Junction: -65°C to 150°C minimum range

Substitute parts are grouped into two categories:

Category 1: Parametric Equivalents — Parts that meet or exceed all electrical specifications of the BAS16TW-7 while maintaining identical package and mounting characteristics. These parts are direct functional replacements with no circuit redesign required.

Category 2: Manufacturer-Recommended Alternatives — Parts that exceed the electrical specifications of the BAS16TW-7 (higher voltage or current ratings) while maintaining package compatibility. These parts provide enhanced performance margins and are suitable for applications where upgraded specifications are acceptable.

Parameter Comparison

Engineering Selection Recommendations

BAS16TW-7-F (Diodes Incorporated)

The BAS16TW-7-F is a parametric equivalent to the BAS16TW-7, offering identical electrical specifications and package configuration. The primary distinction is packaging format: BAS16TW-7-F is supplied in Tape & Reel (TR) configuration versus bulk packaging for the original part. BAS16TW-7-F carries ROHS3 compliance and Active product status, with 155,100 pieces in inventory. This part is the preferred direct replacement for new production and design continuations.

MMBD4148TW-7-F (Diodes Incorporated)

The MMBD4148TW-7-F meets all electrical and mechanical specifications of the BAS16TW-7 with identical performance parameters. The base product number differs (MMBD4148 versus BAS16), but functional equivalence is maintained across all critical parameters. MMBD4148TW-7-F is ROHS3 compliant with Active product status and 20,200 pieces in inventory. This part serves as an alternative source from the same manufacturer.

BAS16VY,135 (Nexperia USA Inc.)

The BAS16VY,135 is a manufacturer-recommended alternative with enhanced electrical specifications: 100 V DC reverse voltage (versus 75 V) and 200 mA average rectified current (versus 150 mA). All other parameters, including forward voltage, reverse recovery time, and package configuration, remain equivalent. BAS16VY,135 is ROHS3 compliant with Active product status and 10,822 pieces in inventory. This part is suitable for applications where higher voltage or current margins are required. Operating temperature range is -55°C to 150°C (versus -65°C to 150°C for the original part).

BAS16TW_R1_00001 (Panjit International Inc.)

The BAS16TW_R1_00001 is a parametric equivalent from an alternative manufacturer, meeting all electrical specifications of the BAS16TW-7. Reverse leakage current is specified at 2.5 µA @ 75 V (versus 1 µA @ 75 V for the original part). Operating temperature range is -55°C to 150°C. BAS16TW_R1_00001 is ROHS3 compliant with Active product status and 12,137 pieces in inventory. This part provides multi-source supply chain flexibility.

Frequently Asked Questions (FAQ)

Q: Can BAS16TW-7-F be used as a direct replacement for BAS16TW-7?

A: Yes. BAS16TW-7-F is a parametric equivalent with identical electrical specifications and package configuration. The only difference is packaging format (Tape & Reel versus bulk). No circuit modifications are required.

Q: What is the difference between BAS16TW-7 and MMBD4148TW-7-F?

A: Both parts are functionally equivalent with identical electrical performance and package type. The base product designation differs, but all critical parameters—voltage rating, current rating, forward voltage, reverse recovery time, and operating temperature—are equivalent. MMBD4148TW-7-F provides an alternative source from the same manufacturer.

Q: Can BAS16VY,135 replace BAS16TW-7 in all applications?

A: BAS16VY,135 meets or exceeds all electrical specifications of BAS16TW-7 and is mechanically compatible. However, the operating temperature range is -55°C to 150°C (versus -65°C to 150°C). Applications requiring operation below -55°C require evaluation. BAS16VY,135 is suitable for applications where higher voltage (100 V) or current (200 mA) margins are acceptable.

Q: What is the significance of the packaging format difference (bulk versus Tape & Reel)?

A: Bulk packaging is suitable for manual assembly or small-volume production. Tape & Reel (TR) packaging is required for automated pick-and-place assembly equipment used in high-volume manufacturing. BAS16TW-7-F, MMBD4148TW-7-F, BAS16VY,135, and BAS16TW_R1_00001 are all supplied in Tape & Reel format, making them compatible with modern production processes.

Q: Why is RoHS compliance important for the BAS16TW-7 substitutes?

A: The original BAS16TW-7 is RoHS non-compliant. All substitute parts listed (BAS16TW-7-F, MMBD4148TW-7-F, BAS16VY,135, and BAS16TW_R1_00001) are ROHS3 compliant, meeting current regulatory requirements for electronic components in many markets. This compliance is mandatory for new designs and production runs targeting regulated industries and regions.

Q: Are there any differences in reverse leakage current between the substitute parts?

A: Yes. BAS16TW-7, BAS16TW-7-F, and MMBD4148TW-7-F specify 1 µA @ 75 V. BAS16VY,135 specifies 500 nA @ 80 V (lower leakage). BAS16TW_R1_00001 specifies 2.5 µA @ 75 V (higher leakage). For applications sensitive to leakage current, BAS16VY,135 offers superior performance.

Q: Can BAS16TW_R1_00001 be used interchangeably with BAS16TW-7?

A: Yes. BAS16TW_R1_00001 is a parametric equivalent with identical voltage and current ratings. The higher reverse leakage current (2.5 µA versus 1 µA) is within acceptable limits for most general-purpose rectifier applications. Operating temperature range is -55°C to 150°C. This part provides multi-source supply flexibility from Panjit International Inc.

Q: What inventory levels are available for each substitute part?

A: BAS16TW-7-F: 155,100 pieces; MMBD4148TW-7-F: 20,200 pieces; BAS16VY,135: 10,822 pieces; BAS16TW_R1_00001: 12,137 pieces. BAS16TW-7-F offers the highest inventory availability for immediate production requirements.

Q: Are all substitute parts surface mount compatible with the original BAS16TW-7 PCB layout?

A: Yes. All substitute parts use the 6-TSSOP (SC-88, SOT-363) package with identical pin configuration and footprint. No PCB redesign is required for any of the listed substitutes.
