Overview
The S08U50600A is a sensitive gate silicon controlled rectifier (SCR) from the S08xxA series, manufactured by Diodes Incorporated. It features a peak repetitive off-state voltage of 600 V and an on-state RMS current rating of 0.8 A at +80°C. The device supports a peak non-repetitive surge current of 10 A and offers high dV/dt immunity with a minimum of 20 V/µs at +110°C. Packaged in a lead-free TO-92 housing, it includes specified minimum and maximum values for gate trigger current, gate trigger voltage, and holding current to facilitate design integration.
Feature Summary
- Sensitive gate architecture enables direct triggering by microcontrollers and logic circuits
- Glass-passivated surface construction ensures reliability and uniformity
- RoHS compliant and halogen-free green package configuration
Applications
- Lighting control systems
- Motor speed control circuits
- General purpose switching applications
Procurement Notes
This component is officially marked as obsolete and discontinued by the manufacturer. Direct procurement from Diodes Incorporated is no longer available. Buyers must verify availability through authorized distributors or secondary markets. Engineering teams should initiate replacement part selection immediately to ensure long-term supply chain stability and avoid production delays.
Selection Notes
Designers requiring this specific electrical profile must evaluate alternative components that match the 600 V blocking voltage and 0.8 A RMS current requirements. Verify that substitute devices maintain compatible gate trigger specifications and offer equivalent thermal resistance characteristics. Ensure any replacement SCR fits within the existing TO-92 footprint constraints if board space cannot be altered.
Part Context
The S08U50600A belongs to the S08xxA series of sensitive gate SCRs. This series was designed for low-power switching tasks where minimal gate drive power is required. The 'U' designation typically indicates specific gate sensitivity parameters compared to other variants like the 'M' series within the same family.
Replacement Considerations
Public confirmed substitute part numbers are not provided in the official documentation. Engineers must identify cross-reference parts independently based on matching electrical ratings and package dimensions.
FAQ
What is the critical rate of rise of off-state voltage (dv/dt) for this device?
The minimum dv/dt immunity is 20 V/µs when measured at a junction temperature of +110°C.
What are the gate trigger current specifications for the S08U50600A?
The gate trigger current (IGT) is specified at a maximum of 50 µA under standard test conditions.
Is this component suitable for high-temperature environments?
Yes, the operating junction temperature range extends up to +110°C, and storage temperatures can reach +150°C.
