Model Selection Tips
To choose a suitable fast recovery rectifier diode, please confirm forward current, reverse voltage, package size, reverse recovery time, operating temperature and circuit frequency. If your product is a low-voltage high-efficiency power supply, Schottky diodes may also be considered. If the circuit requires faster switching speed, ultra fast or super fast recovery diodes may be more suitable.
FAQ
Q1: What is a fast recovery rectifier diode?
It is a rectifier diode with shorter reverse recovery time than a standard rectifier diode. It is suitable for switching circuits and high-frequency rectification where efficiency and recovery speed are important.
Q2: What is the difference between standard rectifier diode and fast recovery diode?
Standard rectifier diodes are mainly used in low-frequency AC/DC conversion. Fast recovery diodes switch off more quickly, helping to reduce switching loss in power supplies, adapters, converters and inverter circuits.
Q3: Which fast recovery diode models are available?
Common models include FR101 to FR107, FR151 to FR157, FR201 to FR207, FR251 to FR257, FR301 to FR307, FR601 to FR607 and 1N4933 to 1N4937. Please contact us if you need equivalent or replacement models.
Q4: Can you provide OEM service?
Yes. Custom marking, package selection, pin length and packing requirements can be arranged according to order quantity and project requirements.
Q5: How can I get a quotation?
Please send the part number, quantity, package, voltage, current and delivery country. We will reply with price, datasheet support and estimated lead time.
