BAV102-TP Equivalent & Substitute Parts

Part Overview

The BAV102-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 150 V DC reverse voltage and 200 mA average rectified current in a Surface Mount Mini MELF package. This part is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing design requirements and procurement needs. Substitute parts maintain electrical compatibility while offering improved availability, enhanced specifications, or alternative packaging configurations.

Substitute Part Grouping Explanation

Substitute parts for the BAV102-TP are classified into two categories based on electrical and mechanical compatibility:

Similar Substitutes maintain identical electrical specifications and are interchangeable within the same application context:

Voltage rating: 150 V DC reverse
Current rating: 200 mA average rectified
Forward voltage: 1.25 V @ 200 mA
Reverse recovery time: 50 ns
Reverse leakage current: 100 nA @ 150 V
Operating temperature range compatibility

Upgrade Substitutes provide enhanced electrical performance while maintaining backward compatibility:

Voltage rating: 150 V DC reverse (maintained)
Current rating: 250 mA average rectified (increased from 200 mA)
Forward voltage: 1.25 V @ 200 mA (maintained)
Reverse recovery time: 50 ns (maintained)
Operating temperature: Extended to 175°C maximum junction temperature
Package compatibility: Mini MELF / DO-213AC / SOD-80

Package variations (Mini MELF, SOD-123, SOD-80) are acceptable substitutes provided mounting type remains Surface Mount and electrical parameters remain within specified tolerances.

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications):

BAV102 (onsemi) is the primary equivalent substitute. This part maintains all electrical parameters of the BAV102-TP while offering active product status, significantly higher inventory availability (586,700 units), and extended operating temperature range (-65°C to 200°C). The onsemi variant is packaged in SOD-80 format, compatible with Mini MELF footprints. ROHS3 compliance and unlimited moisture sensitivity level (MSL 1) are maintained.

BAV20W-TP (Micro Commercial Co) provides an alternative with identical electrical specifications and active product status. This substitute uses SOD-123 packaging instead of Mini MELF, requiring PCB layout modification. Inventory availability is 6,100 units.

For Enhanced Performance (Upgrade Path):

BAV102,135 (Nexperia USA Inc.) and BAV102,115 (NXP Semiconductors) both provide upgraded specifications with 250 mA current rating (25% increase over 200 mA) while maintaining 150 V reverse voltage and 1.25 V forward voltage characteristics. Both parts retain Mini MELF packaging compatibility and 50 ns reverse recovery time. Operating temperature extends to 175°C maximum junction temperature. BAV102,135 offers higher inventory (7,132 units) and ROHS3 compliance certification.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and REACH unaffected status. Moisture sensitivity level remains at MSL 1 (unlimited) across all options. ECCN classification (EAR99) and HTSUS codes are consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can BAV20W-TP replace BAV102-TP in existing designs?

A: BAV20W-TP is electrically equivalent with identical voltage, current, and forward voltage specifications. However, it uses SOD-123 packaging instead of Mini MELF. PCB layout and footprint modifications are required. This substitute is suitable only if board redesign is feasible.

Q: What is the primary advantage of BAV102,135 and BAV102,115 over the original BAV102-TP?

A: Both upgrade substitutes increase average rectified current from 200 mA to 250 mA while maintaining all other electrical parameters. This provides 25% additional current capacity within the same voltage and thermal specifications. Operating temperature extends to 175°C maximum junction temperature.

Q: Is the onsemi BAV102 a direct replacement for BAV102-TP?

A: Yes. The onsemi BAV102 maintains all electrical specifications of the BAV102-TP, including 150 V reverse voltage, 200 mA current rating, and 50 ns reverse recovery time. It is packaged in SOD-80 format, compatible with Mini MELF footprints. Extended operating temperature range (-65°C to 200°C) provides additional thermal margin.

Q: Are there packaging compatibility concerns between Mini MELF and SOD-80 formats?

A: Mini MELF and SOD-80 are equivalent package designations for the same physical form factor. Both are compatible with identical PCB footprints. SOD-123 packaging used in BAV20W-TP is physically different and requires footprint modification.

Q: Which substitute offers the best inventory availability?

A: onsemi BAV102 provides the highest inventory with 586,700 units in stock, followed by BAV102,115 (NXP) with 53,103 units and BAV102,135 (Nexperia) with 7,132 units.

Q: Do all substitutes maintain RoHS3 compliance?

A: BAV102 (onsemi), BAV102,135 (Nexperia), and the original BAV102-TP are confirmed ROHS3 compliant. RoHS status is not specified for BAV20W-TP in the provided data.

Q: What is the temperature operating range difference between the main part and substitutes?

A: BAV102-TP operates from -55°C to 150°C junction temperature. onsemi BAV102 extends this to -65°C to 200°C. BAV102,135 and BAV102,115 specify 175°C maximum junction temperature without lower limit specification.
