MMBD6050 Equivalent & Substitute Parts

Part Overview

The MMBD6050 is a general-purpose rectifier diode manufactured by onsemi, rated for 70 V reverse voltage and 200 mA average rectified current in a surface-mount SOT-23-3 package. This component is classified as obsolete, though inventory remains available. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary for new designs and ongoing production requirements. Substitute parts maintain electrical compatibility within specified parameter ranges while offering active product status and continued manufacturer support.

Substitute Part Grouping Explanation

Substitute parts for the MMBD6050 are classified into two categories based on electrical parameter alignment:

Direct Equivalents (onsemi MMBD6050 Series): Parts MMBD6050LT1G and MMBD6050LT3G are direct parametric equivalents manufactured by onsemi under the same base product number. These parts maintain identical electrical specifications: 70 V reverse voltage, 200 mA average rectified current, 1.1 V forward voltage at 100 mA, and 4 ns reverse recovery time. The primary difference is packaging format (Cut Tape versus Tape & Reel) and product status (both active). These parts are fully interchangeable with the obsolete MMBD6050.

Similar Alternatives (Higher Voltage/Current Ratings): Parts from Central Semiconductor Corp (CMPD4448 and CMPD914 series) and Vishay (MMBD6050-E3-08) offer higher electrical ratings: 75 V reverse voltage and 250 mA average rectified current. These parts are suitable for applications where the MMBD6050 specifications represent minimum requirements. The CMPD914 series exhibits higher reverse leakage current (5 µA to 100 µA at rated voltage) compared to the MMBD6050 (100 nA at 50 V), which may affect circuit performance in sensitive applications.

NXP/Nexperia Alternatives (PMBD6050 Series): Parts PMBD6050,215 and PMBD6050,235 maintain the 70 V reverse voltage specification but offer slightly higher current rating (215 mA) and different forward voltage characteristics (1.25 V at 150 mA). These parts employ fast recovery technology (≤500 ns) compared to the small signal classification of the MMBD6050.

Substitution is determined by three key parameters: reverse voltage rating (must equal or exceed 70 V), average rectified current (must equal or exceed 200 mA), and package compatibility (SOT-23-3 / TO-236-3 form factor).

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications):

MMBD6050LT1G and MMBD6050LT3G are the primary recommended substitutes. Both parts are manufactured by onsemi under the same base product number and maintain 100% electrical equivalence to the obsolete MMBD6050. MMBD6050LT1G is available in Cut Tape packaging (65,100 units in stock), while MMBD6050LT3G is supplied in Tape & Reel format (10,300 units in stock). Both parts carry active product status, ROHS3 compliance, and unlimited moisture sensitivity level (MSL 1). Selection between these two depends on assembly process requirements: Cut Tape for manual or small-batch operations, Tape & Reel for automated production lines.

For Applications Tolerating Higher Ratings:

MMBD6050-E3-08 (Vishay, 801 units in stock) provides identical electrical specifications with active product status and ROHS3 compliance. This part is suitable for designs where component sourcing flexibility is required.

PMBD6050,215 (NXP, 401,086 units in stock) and PMBD6050,235 (Nexperia, 10,957 units in stock) maintain 70 V reverse voltage with increased current capacity (215 mA). These parts employ fast recovery technology and exhibit slightly higher forward voltage (1.25 V at 150 mA versus 1.1 V at 100 mA). These substitutes are appropriate for applications where the MMBD6050 current rating represents a design margin and higher forward voltage drop is acceptable.

For Applications Requiring Higher Voltage/Current Margins:

Central Semiconductor CMPD4448 and CMPD914 series parts offer 75 V reverse voltage and 250 mA current capacity. CMPD4448 variants (BK and TR packaging, 1,045 and 4,407 units respectively) exhibit lower reverse leakage (25 nA at 20 V) and lower forward voltage (1.0 V at 100 mA). CMPD914 variants show variable reverse leakage characteristics depending on part suffix. These parts are suitable for designs requiring enhanced voltage and current margins beyond MMBD6050 specifications.

All recommended substitutes maintain SOT-23-3 package compatibility, ROHS3 compliance, and unlimited moisture sensitivity level. Product status verification confirms active manufacturing for all recommended alternatives except the original MMBD6050.

Frequently Asked Questions (FAQ)

Q: Can MMBD6050LT1G and MMBD6050LT3G be used interchangeably with the obsolete MMBD6050?

A: Yes. Both parts are direct parametric equivalents with identical electrical specifications (70 V, 200 mA, 1.1 V forward voltage, 4 ns recovery time). The difference is packaging format: MMBD6050LT1G is supplied in Cut Tape, while MMBD6050LT3G is supplied in Tape & Reel. Both are manufactured by onsemi with active product status.

Q: What is the difference between PMBD6050,215 and MMBD6050LT1G?

A: PMBD6050,215 (NXP) has a higher current rating (215 mA versus 200 mA) and higher forward voltage (1.25 V at 150 mA versus 1.1 V at 100 mA). It employs fast recovery technology. MMBD6050LT1G maintains the original MMBD6050 specifications exactly. PMBD6050,215 is suitable when higher current capacity is beneficial; MMBD6050LT1G is preferred for exact specification matching.

Q: Are Central Semiconductor CMPD914 parts suitable replacements?

A: CMPD914 parts meet minimum substitution criteria (75 V reverse voltage exceeds 70 V requirement; 250 mA exceeds 200 mA requirement). However, reverse leakage current varies significantly by part suffix: CMPD914 BK PBFREE exhibits 5 µA at 75 V, while CMPD914 TR PBFREE shows 25 nA at 20 V. This variation may affect circuit performance in sensitive applications. Verify reverse leakage requirements before selection.

Q: What packaging options are available for MMBD6050 substitutes?

A: Direct onsemi equivalents are available in two formats: MMBD6050LT1G (Cut Tape) and MMBD6050LT3G (Tape & Reel). Central Semiconductor CMPD4448 and CMPD914 series are available in both Bulk (BK) and Tape & Reel (TR) packaging. NXP PMBD6050,215 is supplied in Bulk; Nexperia PMBD6050,235 is supplied in Tape & Reel. Select packaging based on assembly process requirements.

Q: Do all substitute parts meet RoHS compliance?

A: Yes. All recommended substitute parts carry ROHS3 compliance certification. The original MMBD6050 also meets ROHS3 requirements. All parts maintain unlimited moisture sensitivity level (MSL 1).

Q: What is the temperature operating range for substitute parts?

A: onsemi MMBD6050LT1G and MMBD6050LT3G operate from -55°C to 150°C junction temperature. Vishay MMBD6050-E3-08 operates to 150°C maximum. NXP PMBD6050,215 and Nexperia PMBD6050,235 operate to 150°C maximum. Central Semiconductor CMPD4448 and CMPD914 series operate from -65°C to 150°C, providing extended low-temperature capability.

Q: Can MMBD6050 be replaced with CMPD4448?

A: Yes, with design considerations. CMPD4448 exceeds MMBD6050 specifications in reverse voltage (75 V versus 70 V) and current (250 mA versus 200 mA). Forward voltage is lower (1.0 V at 100 mA versus 1.1 V at 100 mA), and reverse leakage is lower (25 nA at 20 V versus 100 nA at 50 V). These differences may reduce circuit power dissipation. Verify that lower forward voltage does not affect circuit bias point or signal conditioning requirements.

Q: What inventory levels are available for each substitute?

A: MMBD6050LT1G (onsemi): 65,100 units. MMBD6050LT3G (onsemi): 10,300 units. MMBD6050-E3-08 (Vishay): 801 units. PMBD6050,215 (NXP): 401,086 units. PMBD6050,235 (Nexperia): 10,957 units. CMPD4448 BK (Central Semiconductor): 1,045 units. CMPD4448 TR (Central Semiconductor): 4,407 units. CMPD914 BK (Central Semiconductor): 1,028 units. CMPD914 TR (Central Semiconductor): 99,546 units. CMPD914E TR (Central Semiconductor): 23,749 units.
