Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAS16THR are grouped based on strict alignment of electrical and mechanical parameters. The primary substitution criterion is equivalence across voltage rating (100 V DC reverse), current capacity, package type (TO-236-3/SOT-23-3), and recovery characteristics.

Parametric Equivalent Classification: Parts matching all critical parameters including reverse voltage, average rectified current, forward voltage characteristics, reverse recovery time, and junction temperature rating.

Similar Classification: Parts with matching reverse voltage and package compatibility but with reduced average rectified current (200 mA versus 215 mA) or variations in forward voltage, reverse leakage, or capacitance characteristics. These parts function in the same circuit topology but with reduced current margin.

The following parameters determine substitution validity:

• Voltage - DC Reverse (Vr) (Max): 100 V minimum
• Current - Average Rectified (Io): 215 mA (parametric equivalent) or 200 mA (similar)
• Package / Case: TO-236-3, SC-59, SOT-23-3
• Reverse Recovery Time (trr): 4 ns
• Product Status: Active
• RoHS Status: ROHS3 Compliant

Parameter Comparison

Engineering Selection Recommendations

BAS16THVL (Parametric Equivalent): This part is a direct parametric equivalent to the BAS16THR, manufactured by the same supplier (Nexperia USA Inc.) with identical electrical specifications, automotive grade classification, and AEC-Q101 qualification. Both parts share the same reverse voltage (100 V), average rectified current (215 mA), forward voltage characteristics, reverse recovery time (4 ns), and maximum junction temperature (175°C). The BAS16THVL is suitable for direct replacement in all applications where the BAS16THR is specified.

MMBD1201 (Similar - Reduced Current Margin): This onsemi part maintains the 100 V reverse voltage rating and TO-236-3 package compatibility but operates at 200 mA average rectified current, representing a 15 mA reduction from the BAS16THR specification. The forward voltage is lower (1 V @ 200 mA), and reverse leakage is significantly reduced (50 nA @ 50 V). The maximum junction temperature is 150°C, which is 25°C lower than the BAS16THR. This part is suitable for applications where the circuit current requirement does not exceed 200 mA and where the lower junction temperature rating is acceptable. ROHS3 compliance is maintained.

MMBD914LT3G (Similar - Reduced Current and Higher Leakage): This onsemi part maintains the 100 V reverse voltage rating and TO-236-3 package compatibility but operates at 200 mA average rectified current. The reverse leakage current is significantly higher (5 µA @ 75 V) compared to the BAS16THR (500 nA @ 80 V), and capacitance is elevated (4 pF @ 0V, 1MHz). The maximum junction temperature is 150°C. This part is suitable for applications where the circuit current requirement does not exceed 200 mA and where the higher leakage and capacitance characteristics are acceptable. ROHS3 compliance is maintained.

All substitute parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), and Active product status. Selection between similar parts depends on specific circuit requirements regarding current margin, leakage characteristics, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can BAS16THVL be used as a direct replacement for BAS16THR?

A: Yes. The BAS16THVL is a parametric equivalent with identical voltage rating (100 V), current rating (215 mA), forward voltage characteristics, reverse recovery time (4 ns), and maximum junction temperature (175°C). Both parts carry automotive grade classification and AEC-Q101 qualification from Nexperia USA Inc. Direct substitution is valid for all applications.

Q: What is the difference between parametric equivalent and similar classification?

A: Parametric equivalent parts match all critical electrical specifications including reverse voltage, average rectified current, forward voltage, reverse recovery time, and junction temperature. Similar parts maintain reverse voltage and package compatibility but differ in one or more parameters such as average rectified current (200 mA versus 215 mA), reverse leakage, capacitance, or maximum junction temperature. Similar parts function in the same circuit topology but with reduced current margin or altered leakage characteristics.

Q: Can MMBD1201 or MMBD914LT3G be used in applications requiring 215 mA current?

A: No. Both MMBD1201 and MMBD914LT3G are rated for 200 mA average rectified current, which is 15 mA below the BAS16THR specification. These parts are suitable only for applications where the circuit current requirement does not exceed 200 mA. Using these parts in circuits designed for 215 mA operation exceeds the component rating.

Q: Are all substitute parts in the same package?

A: Yes. All listed substitute parts use the TO-236-3, SC-59, or SOT-23-3 package designation, which are mechanically and electrically compatible. The physical footprint and pin configuration are identical, enabling direct PCB-level substitution without layout modification.

Q: What is the impact of the 25°C difference in maximum junction temperature between BAS16THR and MMBD1201/MMBD914LT3G?

A: The BAS16THR is rated to 175°C maximum junction temperature, while MMBD1201 and MMBD914LT3G are rated to 150°C. In high-temperature operating environments or applications with elevated thermal stress, the lower junction temperature rating of the similar parts may limit performance margin. Selection depends on the specific thermal environment and circuit design requirements.

Q: How does reverse leakage current affect circuit performance?

A: Reverse leakage current flows when the diode is reverse-biased. The BAS16THR specifies 500 nA @ 80 V, MMBD1201 specifies 50 nA @ 50 V, and MMBD914LT3G specifies 5 µA @ 75 V. Higher leakage current increases power dissipation and may affect precision analog circuits. MMBD914LT3G exhibits significantly higher leakage (5 µA) and is suitable only for applications where this characteristic is acceptable.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. BAS16THR, BAS16THVL, MMBD1201, and MMBD914LT3G are all ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating. All parts are suitable for lead-free soldering processes and meet environmental compliance requirements.

Q: What packaging options are available for these parts?

A: The BAS16THR is supplied in Tape & Reel (TR) packaging. The BAS16THVL is also supplied in Tape & Reel (TR). The MMBD1201 is supplied in Cut Tape (CT) & Digi-Reel® packaging. The MMBD914LT3G is supplied in Tape & Reel (TR) packaging. Packaging format does not affect electrical or mechanical compatibility; it relates only to order quantity and handling.
