Product Overview
Harris Semiconductor TIP29A: an NPN silicon power transistor in the TO-220 package, rated 60 V collector to emitter and 1 A continuous collector current. It handles general-purpose switching and linear amplification, from relay and lamp drivers to the driver stages of small power supplies and audio amplifiers.
Key Features
- NPN silicon bipolar power transistor
- VCEO 60 V, VCBO 60 V, VEBO 5 V
- Collector current 1 A continuous, 3 A peak
- Power dissipation 30 W at 25 C case temperature
- DC current gain hFE 40 minimum at 0.2 A, 15 to 75 at 1 A (VCE 4 V)
- Transition frequency fT 3 MHz minimum
- TO-220 case with a metal mounting tab and screw hole
Applications
- Switching a relay coil, solenoid or lamp from a logic or microcontroller output through a base resistor
- Driver and pass stages in small linear power supplies
- Repairing amplifiers, chargers and control boards whose parts list calls for a TIP29A
- Bench and hobby builds that need a screw-down transistor for loads under an amp
Frequently Asked Questions
How much load can the TIP29A handle?
1 A continuous collector current and 3 A peak, at up to 60 V collector to emitter. Dissipation is 30 W with the case held at 25 C, so anything past light duty wants a heatsink on the tab. Gain falls to 15 minimum at 1 A, so size the base drive for it.
Which lead is the base?
Pin 1 is the base, pin 2 the collector and pin 3 the emitter.
This TIP29A wears the logo of Harris Semiconductor, the division that became Intersil in 1999. Bolt it down wherever a logic line needs to move something heavier than itself.
