Substitute Part Grouping Explanation
Substitute parts for the BAS116 are classified into three functional categories based on electrical parameter alignment:
Category 1: Direct Electrical Equivalents (85 V Rating) Parts maintaining the original 85 V reverse voltage specification with identical 215 mA current rating and matching forward voltage characteristics. These parts are interchangeable without circuit redesign.
Category 2: Reduced Voltage Equivalents (75 V Rating) Parts with 75 V reverse voltage specification, representing a 10 V reduction from the original rating. These parts maintain 215 mA current rating and identical forward voltage. Selection requires circuit analysis to confirm voltage margin adequacy.
Category 3: Reduced Voltage and Current Equivalents (75 V / 200 mA Rating) Parts with both reduced reverse voltage (75 V) and reduced average rectified current (200 mA). These parts maintain forward voltage and recovery time characteristics. Selection requires verification of circuit current requirements.
Category 4: Reduced Voltage with Enhanced Recovery (70 V Rating, Fast Recovery) Parts with 70 V reverse voltage and 215 mA current rating, featuring fast recovery characteristics (4 ns trr) and reduced capacitance. These parts differ in recovery speed classification and leakage current specifications.
Substitution logic is determined by the following key parameters:
- Voltage - DC Reverse (Vr) (Max)
- Current - Average Rectified (Io)
- Voltage - Forward (Vf) (Max) @ If
- Reverse Recovery Time (trr)
- Package / Case compatibility
- RoHS and automotive qualification status

Engineering Selection Recommendations
Primary Substitutes (Full Electrical Equivalence)
BAS116-7-F and BAS116Q-7-F from Diodes Incorporated maintain the original 85 V reverse voltage and 215 mA current specifications. Both parts are active and ROHS3 compliant. BAS116Q-7-F includes AEC-Q101 automotive qualification, suitable for automotive applications. BAS116Q-13-F provides identical electrical specifications with automotive qualification in alternative packaging configuration.
Secondary Substitutes (Reduced Voltage, Maintained Current)
BAS116,215 and BAS116,235 from Nexperia USA Inc. reduce reverse voltage to 75 V while maintaining 215 mA current rating. Both parts are active, ROHS3 compliant, and carry AEC-Q100 automotive qualification. These parts are suitable for applications where 75 V reverse voltage margin is adequate.
MMBD4148,215 from Nexperia USA Inc. provides 75 V reverse voltage with 215 mA current but features fast recovery characteristics (4 ns trr) compared to the standard 3 µs recovery time of the original part. This part is active and ROHS3 compliant.
Tertiary Substitutes (Reduced Voltage and Current)
BAS116-TP from Micro Commercial Co and BAS116_R1_00001 from Panjit International Inc. reduce both reverse voltage to 75 V and current to 200 mA. Both parts are active and ROHS3 compliant. These parts require circuit analysis to confirm current adequacy.
Reduced Voltage with Enhanced Recovery
PMBD6050,215 from NXP Semiconductors and PMBD6050,235 from Nexperia USA Inc. provide 70 V reverse voltage with 215 mA current and fast recovery characteristics (4 ns trr). PMBD6050,235 is ROHS3 compliant and active. These parts feature reduced capacitance (1.5 pF) compared to the original specification.
Selection priority is determined by application voltage margin requirements, current demands, and compliance certifications. Parts with maintained 85 V ratings provide direct substitution without circuit analysis. Reduced voltage parts require verification of circuit operating conditions.
Frequently Asked Questions (FAQ)
Q: Can BAS116-7-F directly replace the discontinued BAS116?
A: Yes. BAS116-7-F maintains identical electrical specifications: 85 V reverse voltage, 215 mA current, 1.25 V forward voltage, and 3 µs recovery time. The part is active and ROHS3 compliant. Packaging is SOT-23-3, matching the original specification.
Q: What is the difference between BAS116-7-F and BAS116Q-7-F?
A: Both parts maintain identical electrical specifications and packaging. BAS116Q-7-F includes AEC-Q101 automotive qualification, suitable for automotive applications. BAS116-7-F is the standard industrial grade equivalent.
Q: Can I use BAS116,215 (75 V) in place of the original BAS116 (85 V)?
A: BAS116,215 is suitable only if circuit analysis confirms that 75 V reverse voltage provides adequate margin for the application. The 10 V reduction in reverse voltage rating must be evaluated against circuit peak voltage conditions. This part is ROHS3 compliant and carries AEC-Q100 automotive qualification.
Q: What is the difference between standard recovery and fast recovery diodes in this list?
A: The original BAS116 and most substitutes feature standard recovery with 3 µs reverse recovery time. MMBD4148,215 and PMBD6050 series parts feature fast recovery with 4 ns reverse recovery time. Fast recovery reduces switching losses but increases capacitance sensitivity. Selection depends on circuit switching frequency requirements.
Q: Are all substitute parts ROHS3 compliant?
A: Most active substitutes are ROHS3 compliant. PMBD6050,215 from NXP Semiconductors does not specify RoHS status in the provided data. Verify compliance requirements for specific applications before selection.
Q: Can I use BAS116-TP or BAS116_R1_00001 (200 mA) in circuits designed for 215 mA?
A: These parts are suitable only if circuit analysis confirms that 200 mA average rectified current is adequate for the application. The 15 mA reduction in current rating must be evaluated against circuit current demands. Both parts are active and ROHS3 compliant.
Q: What packaging options are available for BAS116 substitutes?
A: All substitutes use surface mount packages compatible with SOT-23-3 or TO-236-3 footprints. Diodes Incorporated parts use SOT-23-3 designation. Nexperia and NXP parts use TO-236AB designation. Micro Commercial Co and Panjit parts use SOT-23 designation. Physical footprints are compatible across these designations.
Q: Which substitute part offers the best availability?
A: PMBD6050,215 from NXP Semiconductors shows the highest inventory at 401,086 pieces. BAS116,235 from Nexperia USA Inc. shows 116,588 pieces. BAS116-7-F from Diodes Incorporated shows 155,300 pieces. Availability varies by distributor and time.
Q: Are there automotive-qualified alternatives to the original BAS116?
A: Yes. BAS116Q-7-F and BAS116Q-13-F from Diodes Incorporated carry AEC-Q101 automotive qualification. BAS116,215 and BAS116,235 from Nexperia USA Inc. carry AEC-Q100 automotive qualification. These parts are suitable for automotive applications requiring qualification documentation.
