Overview
The PS2533L-1-V-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates an AlGaAs LED with an NPN silicon photodarlington detector in a 4-SMD gull-wing package. Key electrical specifications include a maximum collector-emitter voltage of 350 V and a peak forward current of 80 mA. The device offers a high current transfer ratio ranging from 1500% to 6500%. It provides 5000 Vrms isolation voltage and operates within a temperature range of -55°C to +100°C.
Feature Summary
- High current transfer ratio for efficient signal transmission
- 5000 Vrms insulation voltage for robust isolation
- Wide operating temperature range suitable for industrial environments
Applications
- Industrial automation control systems
- Power supply feedback loops
- Microcontroller input isolation
Procurement Notes
Verify the specific suffix 'V-A' corresponds to the 4-SMD gull-wing surface mount package configuration. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the ordering part number matches the required lead time and availability constraints before finalizing procurement orders.
Selection Notes
Select this component when high gain is required due to its photodarlington output structure. The 350 V collector-emitter voltage rating supports higher voltage switching applications compared to standard 50 V variants. Consider the 100 µs rise and fall times, which are slower than phototransistor types, making it suitable for lower frequency switching or DC coupling applications.
Part Context
This device belongs to the PS2533L series of optically coupled isolators. The series combines an AlGaAs light emitting diode with an NPN silicon photodarlington connected phototransistor. The 'L' designation typically indicates specific packaging or performance characteristics within the broader PS2533 family line.
Replacement Considerations
PS2533L-1-A is a DIP-4 variant of the same electrical specification. PS2533L-1-V-E3-A is a lead-free version of the SMD package. Verify pinout compatibility and package dimensions when substituting.
