Overview
The 1SV233-TB-E is a single PIN diode manufactured by onsemi, designed for VHF and UHF applications. It operates with a maximum reverse voltage of 50V and a forward current rating of 50mA. The device features a typical interterminal capacitance of 0.23pF at 50V reverse bias and a typical series resistance of 5Ω at 100MHz. Packaged in the CP (SOT-23) format, it supports high-density mounting. The component is lead-free compliant and supplied in embossed tape reels containing 3,000 pieces per reel.
Feature Summary
- Very small-sized package facilitates high-density mounting
- Small interterminal capacitance suitable for RF switching
- Low forward series resistance for efficient signal handling
Applications
- VHF and UHF frequency circuits
- Automatic Gain Control (AGC) systems
- RF switching applications
Procurement Notes
Verify the ordering suffix TB-E corresponds to the CP package type and embossed taping specification. Confirm the minimum packing quantity is 3,000 pieces per reel. Ensure the procurement matches the Pb Free designation required for the specific manufacturing lot.
Selection Notes
Select this component when low interterminal capacitance and small series resistance are critical for VHF or UHF performance. Verify that the 50V reverse voltage and 50mA forward current ratings exceed the circuit requirements. Consider the SOT-23 footprint constraints during PCB layout design.
Part Context
This part belongs to the 1SV233 family of single PIN diodes from onsemi. It is specifically engineered for compact RF designs requiring minimal parasitic effects. The device serves as a fundamental switching element in communication equipment operating within the VHF and UHF bands.
Replacement Considerations
Check datasheets for other single PIN diodes in the SOT-23 package. Verify matching electrical parameters such as interterminal capacitance below 0.23pF and series resistance near 5Ω. Ensure the replacement supports similar VHF/UHF frequencies and AGC functionality.
