Transistor 2SC829 NPN, 30mA TO-92
2SC829 RF Transistor - Built for FM/AM Radio Front-Ends
The 2SC829 is a Silicon NPN epitaxial planar transistor from Panasonic, purpose-built for high-frequency amplification rather than general-purpose switching. It is commonly found in the RF, oscillator, mixer and IF stages of FM and AM radio receivers, where its high transition frequency and low noise are put to good use.
Functions & Applications
- High Transition Frequency: Typical fT around 230MHz suits RF amplifier and oscillator stages.
- Low-Noise RF Design: Optimized for the front-end and IF stages of FM/AM radio receivers.
- Standard TO-92 Package: Easy through-hole soldering for repairs and classic radio projects.
- Compact Silicon NPN: Low collector current design keeps power draw minimal in signal circuits.

Frequently Asked Questions
Q: What is the 2SC829 used for?
A: It is a small-signal RF transistor intended for the RF amplifier, oscillator, mixer and IF stages of FM/AM radio receivers, not for general switching.
Q: Can the 2SC829 be used as a general-purpose switch?
A: It can switch small low-current loads within its 30mA/20V rating, but its epitaxial planar RF design makes it far better suited to high-frequency amplification than logic-level switching.
Notes
Legacy Panasonic RF transistor originally designed for analog FM/AM radio circuits; still useful for retro radio repairs and RF hobby projects.
Note: Price refers to one (1) piece. The component is shipped in bulk without individual packaging.
