Voltage - DC Reverse (Vr) (Max): 200 V
Mounting Type: Surface Mount

Current Rating Considerations: Substitute parts are grouped by average rectified current capacity. The FFB20UP20DN operates at 10A per diode. Substitutes with equal or higher current ratings (10A, 20A) are direct replacements. Parts with lower current ratings (5A, 8A) are suitable only for applications with reduced current requirements.

Performance Parameters: Forward voltage, reverse recovery time, and reverse leakage current vary among substitutes but remain within acceptable ranges for fast recovery rectifier applications. These variations reflect different semiconductor technologies (Standard vs. Super Barrier) and manufacturing processes.

Product Status: The FFB20UP20DN is obsolete. Active equivalent and substitute parts are preferred for new designs and ongoing procurement.

Frequently Asked Questions (FAQ)

Q: Can FFB20UP20DN-F085 directly replace FFB20UP20DN? A: Yes. FFB20UP20DN-F085 is the parametric equivalent with identical electrical specifications. The primary difference is product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. standard). FFB20UP20DN-F085 includes AEC-Q101 automotive qualification.

Q: What is the difference between Standard and Super Barrier technology in these diode arrays? A: Super Barrier technology (SBR series from Diodes Incorporated) typically exhibits lower forward voltage drop and faster reverse recovery time compared to Standard technology. The choice depends on application requirements for power dissipation and switching speed.

Q: Can I use SBR10200CTB (5A) in place of FFB20UP20DN (10A)? A: SBR10200CTB is suitable only if your application current requirement does not exceed 5A per diode. Using a lower-rated device in a 10A application will result in device failure or reduced reliability.

Q: Are all substitute parts available in the same D2PAK package? A: Yes. All listed substitute parts use TO-263-3, D2PAK (2 Leads + Tab), TO-263AB packaging, ensuring mechanical and thermal compatibility with FFB20UP20DN.

Q: What is the difference between SBR20A200CTB and SBR20A200CTB-13? A: Both parts have identical electrical specifications. The primary difference is packaging: SBR20A200CTB is supplied in Tube packaging, while SBR20A200CTB-13 is supplied in Tape & Reel (TR) packaging.

Q: Does operating temperature range affect substitution? A: FFB20UP20DN operates from -55°C to 175°C. Most substitute parts operate from -65°C to 175°C, providing extended low-temperature capability. STTH1602CG-TR specifies 175°C maximum junction temperature. Verify application temperature requirements before selection.

Q: Are these parts suitable for automotive applications? A: FFB20UP20DN-F085 includes AEC-Q101 automotive qualification. Other substitute parts are ROHS3 compliant but do not carry explicit automotive qualification in the provided specifications. Verify automotive requirements with the component manufacturer if needed.

Q: What is the significance of reverse leakage current differences? A: Reverse leakage current (Ir) varies among substitutes: FFB20UP20DN specifies 10µA @ 200V, while SBR20A200CTB specifies 100µA @ 200V. Higher leakage current increases power dissipation in reverse bias conditions. Select based on application thermal and power budget requirements.

Q: Can I use SBR40U200CTB (20A) in a design rated for 10A? A: Yes. A higher-rated device (20A) can be used in a 10A application without electrical or thermal concerns. The device will operate within its safe operating area with margin. Verify PCB thermal design accommodates the device package.
