• High Q factor performance at 50 MHz for efficient signal handling
• Wide operating temperature range suitable for diverse environmental conditions
• Compact SOT-23-3 surface-mount footprint for space-constrained designs

Applications

• RF oscillator tuning circuits
• Voltage-controlled oscillator (VCO) implementations
• Frequency modulation modules
• Phase-locked loop (PLL) filter networks

Procurement Notes

Verify part authenticity through authorized Diodes Incorporated distributors or certified suppliers. Confirm RoHS3 compliance status and check for recent Product Change Notices (PCN) regarding manufacturing site changes. Ensure packaging specifications match design requirements, noting that standard supplier packaging may vary. Validate datasheet revisions against current engineering specifications before finalizing procurement orders.

Selection Notes

Select this component when a single varactor with 25 V reverse voltage rating is required in an SOT-23-3 package. Consider the 10.5 pF baseline capacitance and 6.0 capacitance ratio for tuning range requirements. Evaluate thermal management needs given the 150°C maximum junction temperature limit. Compare Q factor specifications against circuit bandwidth requirements to ensure adequate performance at target frequencies.

Part Context

The ZC830BTC is part of the ZC830B series of varactor diodes from Diodes Incorporated. This series provides single-channel varactor solutions in compact surface-mount packages. The ZC830BTA variant shares identical electrical characteristics but may differ in packaging suffixes or specific manufacturer lot codes. Both components serve similar RF tuning applications within the same product family guidelines.

Replacement Considerations

Direct substitutes include other single varactor diodes in SOT-23-3 packages with comparable 25 V ratings and similar capacitance values. Verify pinout compatibility and electrical parameter overlaps before substitution. Check for updated PCNs affecting legacy parts like the ZC830BTA if considering cross-referencing within the same manufacturer's portfolio.
