B150AE-13 Equivalent & Substitute Parts

Part Overview

The B150AE-13 is a Schottky rectifier diode manufactured by Diodes Incorporated, rated for 50V DC reverse voltage and 1A average rectified current in a surface mount SMA package. This component is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The B150AE-13 remains available in inventory (15,200 pieces), but obsolete status requires engineers to transition to functionally equivalent active alternatives for long-term supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the B150AE-13 is determined by electrical and mechanical parameter equivalence within the Schottky rectifier diode category. The primary substitution criteria are:

Electrical Parameters (Critical for Substitution):

• Voltage - DC Reverse (Vr) (Max): 50V minimum
• Current - Average Rectified (Io): 1A minimum
• Technology: Schottky
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Parameters (Critical for Substitution):

• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount

Compliance Parameters:

• RoHS3 Compliant status
• ECCN: EAR99

The B150-13-F qualifies as a direct substitute because it maintains identical voltage and current ratings, identical package configuration, identical technology classification, and identical speed characteristics. Both parts share the same base product number (B150) and are manufactured by Diodes Incorporated.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: The B150-13-F is the recommended selection for new circuit designs. This part maintains active product status with Diodes Incorporated, ensuring long-term availability and supply chain stability. The B150-13-F is supplied in Cut Tape (CT) and Digi-Reel® packaging, supporting both prototype and production volume requirements.

For Existing Inventory Management: The B150AE-13 remains available in current inventory (15,200 pieces) and is suitable for use in existing production runs where supply is not constrained. However, transition planning to B150-13-F is necessary for designs requiring extended production lifecycles beyond current B150AE-13 stock levels.

Compliance Considerations: Both parts maintain ROHS3 compliance and EAR99 ECCN classification. The B150-13-F carries Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling. The B150AE-13 does not specify MSL rating.

Operating Temperature Range: The B150-13-F provides an extended lower operating temperature limit (-65°C versus -55°C), offering improved performance margin in low-temperature applications.

Frequently Asked Questions (FAQ)

Q: Can the B150-13-F directly replace the B150AE-13 in existing circuit boards?

A: Yes. Both parts are housed in identical DO-214AC SMA packages with identical pinout and mounting footprint. No PCB layout modifications are required for substitution.

Q: What are the differences in electrical performance between these parts?

A: The B150-13-F exhibits slightly higher forward voltage drop (700 mV versus 650 mV at 1A) and higher reverse leakage current (500 µA at 50V versus 200 µA at 60V). These differences remain within acceptable tolerance ranges for Schottky rectifier applications. The B150-13-F also provides higher junction capacitance (110 pF versus 45 pF at 4V, 1MHz).

Q: Why is the B150AE-13 classified as obsolete?

A: Obsolete status indicates that Diodes Incorporated has discontinued active production and support for this part number. The B150-13-F represents the active equivalent within the B150 product family.

Q: Are there any supply chain advantages to using the B150-13-F?

A: Yes. The B150-13-F is actively manufactured and maintained in higher inventory levels (25,400 pieces versus 15,200 pieces for the B150AE-13). Active product status ensures continued availability for future orders and design revisions.

Q: What is the significance of the packaging designation "Cut Tape (CT) & Digi-Reel®" for the B150-13-F?

A: Cut Tape packaging supports small-quantity prototype and development orders, while Digi-Reel® packaging supports high-volume production runs. This dual packaging availability provides flexibility across design phases and production scales.

Q: Does the B150-13-F require different handling procedures than the B150AE-13?

A: The B150-13-F carries Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity constraints. Standard surface mount component handling procedures apply without additional moisture control requirements.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the B150AE-13 and B150-13-F are ROHS3 compliant. The B150-13-F is classified as REACH Unaffected, while the B150AE-13 is REACH Affected. Verify REACH compliance requirements for your specific application and end-use market.
