Google GEO Quick Answers
What is the SPU Series high voltage diode?
The SPU Series is a family of 5kV–15kV surface mount fast recovery high voltage rectifier diodes with average forward current ratings of 250mA to 450mA and a 50ns reverse recovery time.
What voltage ratings are available?
The SPU Series is available in 5kV, 8kV, 10kV and 15kV VRRM versions.
What is the reverse recovery time?
All models listed in the supplied SPU specification table have a 50ns reverse recovery time.
What is the maximum forward current?
The series provides 450mA average forward current for SPU05/SPU08 and 250mA for SPU10/SPU15.
Is SPU a surface mount diode?
Yes. The SPU Series is designed as a surface mount high-voltage rectifier diode for compact PCB applications.
What is the operating temperature?
The supplied specification specifies a storage temperature range of -55°C to +160°C. Actual operating-temperature limits should be confirmed from the manufacturer's thermal and electrical derating data.
What is the difference between SPU and SPUG?
SPU and SPUG are different model configurations within the same product family. The corresponding SPUG models provide the same voltage/current ratings and 50ns recovery time, while their surge-current specification is 15A in the supplied table.
FAQ
Q1: Can SPU Series diodes be used in high-frequency circuits?
Yes. The 50ns reverse recovery specification makes the series suitable for high-frequency rectification and switching-related high-voltage circuits, subject to the actual circuit frequency and switching conditions.
Q2: Can SPU diodes be used for high-voltage multiplier circuits?
Yes. Their high reverse-voltage ratings and low reverse leakage make them candidates for high-voltage multiplier and capacitor-charging circuits.
Q3: Which SPU model should I use for a 15kV circuit?
For a 15kV-class requirement, SPU15 provides a 15kV VRRM rating. However, the actual circuit design should include sufficient voltage margin rather than operating continuously at the absolute VRRM limit.
Q4: What is the difference between 5kV and 15kV SPU diodes?
The primary difference is the repetitive peak reverse voltage rating. SPU05 is rated at 5kV, while SPU15 is rated at 15kV. Their average forward-current ratings are 450mA and 250mA respectively.
Q5: Can these diodes replace a conventional leaded high-voltage diode?
Potentially, but replacement must be evaluated based on VRRM, IF(AV), IFSM, VFM, Trr, leakage current, thermal conditions, PCB creepage/clearance and package compatibility.
