Overview
The SFH620A-2X007T is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output and supports AC or DC input types. The device provides 5300 Vrms isolation voltage and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum collector current of 100 mA, and a forward current of 60 mA. The typical rise and fall times are 2 µs and 2.3 µs respectively. The Current Transfer Ratio (CTR) ranges from 63% to 200% at 10 mA. It is housed in a 4-SMD Gull Wing package.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits using infrared LED and phototransistor technology.
- Supports both AC and DC input signal types for versatile interface applications.
- Features fast switching characteristics with typical rise and fall times under 3 microseconds.
Applications
- Digital logic signal transmission and level shifting
- Power supply control and switching circuits
- Electrical insulation isolation between circuit stages
Procurement Notes
Verify the specific suffix X007T corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the CTR binning matches the design requirements for the target application. Ensure the 4-SMD gull wing footprint aligns with the PCB layout specifications. Cross-reference the manufacturer datasheet for any updates on RoHS compliance status or recommended soldering profiles.
Selection Notes
Select this component when high isolation voltage and moderate speed are required for single-channel signal transfer. The wide operating temperature range makes it suitable for industrial environments. Consider the CTR range if precise gain control is necessary. Compare against through-hole variants if board space constraints allow for larger packages. Evaluate power dissipation limits relative to the expected forward current usage.
Part Context
This part belongs to the SFH620A series of transistor output optocouplers. It shares common family characteristics such as the NPN phototransistor output structure and similar electrical ratings with other variants like SFH620A-1 and SFH620A-3. The primary distinction lies in the Current Transfer Ratio (CTR) classification and the packaging configuration. The X007T suffix specifically denotes the surface mount gull wing package with tape and reel delivery.
Replacement Considerations
SFH620A-1X007T offers a lower CTR range (40-125%). SFH620A-3X007T provides a higher CTR range (100-320%). SFH620AGB-X007T is a related variant with different CTR specifications. Verify pinout compatibility and thermal performance before substitution.
