SS22 Alternative / Equivalent / Replacement - 2A 20V Schottky Diode SMA SMB | YINT
Are you searching for an SS22 alternative, SS22 equivalent, or SS22 replacement? YINT Electronics offers a direct SS22 substitute in both SMA and SMB packages with identical electrical specifications to ON Semiconductor, Vishay, and Diodes Incorporated parts for low-power rectification and polarity protection.
1. Product Overview
The SS22 is a 2A 20V Schottky barrier rectifier diode for low-voltage high-frequency rectification and polarity protection circuits. It features a low forward voltage drop of 0.55V max, 50A peak surge current, and fast switching capability. The SS22 is a JEDEC-registered industry standard number available in SMA (DO-214AC) and SMB (DO-214AA) packages, making it a drop-in replacement across all major manufacturers. It operates from -55°C to +125°C and is suitable for DC-DC converters, freewheeling diodes, and reverse polarity protection in consumer and industrial electronics.
2. Key Features
Reverse Voltage: 20V — 20V Vrrm for 12V/15V circuits
Forward Voltage: 0.55V max — Low VF reduces power loss
Surge Current: 50A — Peak forward surge current
Reverse Leakage: 0.5mA max — Low standby power
Fast Switching: Schottky barrier technology
Junction Temp: -55°C to +125°C
Package: SMA (DO-214AC) / SMB (DO-214AA)
RoHS Compliant: Lead-free

8. FAQ
Q1: Is YINT SS22 a direct replacement for ON Semiconductor or Vishay SS22?
A: Yes. Identical electrical specs and package dimensions. No PCB redesign needed.
Q2: What is the forward voltage drop of SS22 at 2A?
A: 0.55V maximum at 2A forward current at 25C junction temperature.
Q3: What is the difference between SS22-SMA and SS22-SMB?
A: SS22-SMA is DO-214AC (smaller), SS22-SMB is DO-214AA (larger, better thermal dissipation).
Q4: Can SS22 be used for 24V systems?
A: No. Use SS24 (40V) or higher voltage for 24V systems.
Q5: What is the surge current rating?
A: 50A peak forward surge for an 8.3ms single half-sine wave.
Q6: Does YINT provide free samples?
A: Yes. Contact YINT with your project details.
