B290-13 Schottky Diode 90V 2A SMB Equivalent & Substitute Parts

Part Overview

The B290-13 is a Schottky rectifier diode manufactured by Diodes Incorporated, rated for 90V DC reverse voltage and 2A average rectified current in a Surface Mount SMB (DO-214AA) package. This part is discontinued at DiGi Electronics, necessitating identification of equivalent and substitute components for ongoing design support and production requirements. Equivalent parts maintain identical electrical specifications, while substitute parts offer compatible performance within defined parameter tolerances for the SMB package category.

Substitute Part Grouping Explanation

Substitution of the B290-13 is determined by the following critical parameters:

Mandatory Matching Parameters:

Package / Case: DO-214AA, SMB (physical and thermal compatibility)
Technology: Schottky (functional rectification characteristics)
Mounting Type: Surface Mount (assembly process compatibility)
Current - Average Rectified (Io): 2A minimum (load handling capability)
Voltage - DC Reverse (Vr) (Max): 90V minimum (circuit protection requirement)
Speed: Fast Recovery ≤ 500ns, > 200mA (Io) (switching performance)

Allowable Parameter Variations:

Voltage - DC Reverse (Vr) (Max): Parts rated 90V or higher are acceptable
Voltage - Forward (Vf) (Max) @ If: Variations within ±100 mV are acceptable for 2A operation
Current - Reverse Leakage @ Vr: Variations acceptable within manufacturer specifications
Operating Temperature - Junction: Minimum -65°C and maximum 150°C required

Substitute parts are classified into two categories: Parametric Equivalents (identical specifications, different packaging or product status) and Manufacturer Recommended Substitutes (compatible performance with allowable parameter variations).

Engineering Selection Recommendations

Parametric Equivalents (Direct Replacement):

B290-13-F and B290Q-13-F are parametric equivalents of the B290-13, maintaining identical electrical specifications (90V, 2A, 790 mV forward voltage). Both parts are manufactured by Diodes Incorporated and are in Active product status. B290-13-F is available in Cut Tape and Digi-Reel packaging, while B290Q-13-F is supplied in Tape & Reel format and includes AEC-Q101 automotive qualification. Both are ROHS3 compliant, addressing regulatory requirements not met by the discontinued B290-13.

Manufacturer Recommended Substitutes (Compatible Performance):

STPS2H100U and STPS2H100UY (STMicroelectronics) are direct functional substitutes with identical 2A current rating and 790 mV forward voltage at 2A. These parts are rated for 100V reverse voltage, providing additional voltage margin. STPS2H100UY includes automotive grade qualification and extended operating temperature range (-40°C to 175°C). Both are ROHS3 compliant and available in high inventory quantities.

SBRS8190T3G-VF01 (onsemi) maintains the 90V rating and 2A current capacity with AEC-Q101 automotive qualification. Forward voltage is specified at 1A (750 mV), and reverse leakage is 500 µA at 90V. This part supports extended junction temperature operation to 175°C.

SS29 (Taiwan Semiconductor Corporation) provides 90V/2A performance with 850 mV forward voltage at 2A and 100 µA reverse leakage at 90V. Operating temperature range is -55°C to 150°C, matching the original B290-13 upper limit.

Current-Limited Substitutes (Reduced Current Rating):

STPS1H100U and STPS1H100UY (STMicroelectronics) are rated for 1A average rectified current, half the B290-13 specification. These parts are suitable only for applications where circuit current requirements do not exceed 1A. Both are ROHS3 compliant; STPS1H100UY includes automotive qualification.

Over-Current Capable Substitute:

STPS3H100U (STMicroelectronics) is rated for 3A average rectified current with 100V reverse voltage. This part accommodates higher current demands than the B290-13 while maintaining SMB package compatibility and ROHS3 compliance.

Legacy Substitute:

S210 (Fairchild Semiconductor) is rated for 100V/2A with 850 mV forward voltage at 2A. This part is in Active status but lacks documented RoHS compliance information and is supplied in Bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can B290-13-F directly replace B290-13 in existing designs?

A: Yes. B290-13-F is a parametric equivalent with identical electrical specifications (90V, 2A, 790 mV forward voltage). The primary differences are product status (Active vs. Discontinued) and RoHS compliance (ROHS3 vs. Non-compliant). Physical package and thermal characteristics are identical.

Q: What is the difference between B290-13-F and B290Q-13-F?

A: Both are parametric equivalents with identical electrical specifications. B290-13-F is supplied in Cut Tape and Digi-Reel packaging for standard applications. B290Q-13-F is supplied in Tape & Reel format and includes AEC-Q101 automotive qualification, suitable for automotive and high-reliability applications.

Q: Can STPS2H100U replace B290-13 in a 90V circuit?

A: Yes. STPS2H100U maintains the 2A current rating and 790 mV forward voltage at 2A. The 100V reverse voltage rating provides additional safety margin above the 90V circuit requirement. All other electrical parameters are compatible.

Q: Why do some substitutes have different forward voltage specifications?

A: Forward voltage is measured at specific current levels. The B290-13 specifies 790 mV at 2A. Some substitutes specify forward voltage at different current levels (e.g., 750 mV at 1A for SBRS8190T3G-VF01). Actual forward voltage varies with current; specifications at different measurement points reflect manufacturer characterization practices.

Q: Are STPS1H100U and STPS1H100UY suitable for B290-13 replacement?

A: These parts are suitable only if circuit current requirements do not exceed 1A. Both are rated for 1A average rectified current, half the B290-13 specification. Using these parts in circuits requiring 2A operation will result in device overstress and failure.

Q: What is the significance of AEC-Q101 qualification on B290Q-13-F and STPS2H100UY?

A: AEC-Q101 is an automotive industry qualification standard. Parts bearing this qualification have undergone additional reliability testing and are approved for automotive applications. This qualification is not required for general industrial or consumer applications.

Q: Can S210 be used as a substitute for B290-13?

A: S210 is functionally compatible with 100V/2A ratings and SMB package compatibility. However, S210 lacks documented RoHS compliance information and is supplied in Bulk packaging rather than tape formats. Use is limited to applications where RoHS compliance is not required and bulk packaging is acceptable.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging supplies components on tape that must be cut to length for placement. Tape & Reel (TR) packaging supplies components on continuous reel format for automated assembly equipment. Both formats are compatible with standard surface mount assembly processes; selection depends on production equipment capability.

Q: Why is reverse leakage current specified at different values across substitutes?

A: Reverse leakage current is a temperature and voltage-dependent parameter that varies with manufacturing process and device design. The B290-13 specifies 7 mA at 90V, while B290-13-F specifies 7 µA at 90V. This three-order-of-magnitude difference reflects improved manufacturing processes in the newer part. Both values are within acceptable operating ranges for Schottky diodes.

Q: Is ROHS3 compliance required for B290-13 replacement?

A: ROHS3 compliance is required for products sold into European Union markets and many other regulated regions. The original B290-13 is non-compliant. Equivalent parts B290-13-F and B290Q-13-F are ROHS3 compliant and are recommended for new designs and ongoing production to ensure regulatory compliance.

Q: Can STPS3H100U be used in place of B290-13?

A: Yes. STPS3H100U is rated for 3A average rectified current, exceeding the B290-13 specification of 2A. The 100V reverse voltage rating provides additional margin above 90V. All other electrical parameters are compatible. This part is suitable for applications requiring higher current capacity than the original design.
