TTC5200 power Transistor is the newer and better version of the famous 2SC5200 power transistor. It is a through-hole NPN silicon transistor and comes only in a TO-3P package.
First released in 2011 by TOSHIBA, aimed at replacing 2SC5200 is cheaper and superior. Hence, should be the first choice between the two.
Although the specs of TTC5200 and 2SC5200 seem similar while looking at the datasheet, the former is indeed superior to the latter. Laboratory tests on TT transistors showed outstanding endurance levels. This means that these ones can withstand extreme temperatures, and they are highly durable.
They withstood endurance tests at high temperatures exceeding the maximum junction temperature quoted in Toshiba’s specifications.
Note: 2SA1943 is the complementary transistor of 2SC5200 and TTA1943 is the complementary transistor of TTC5200.
What is TTC5200 Transistor?
TTC5200 is an NPN Power transistor used in Audio frequency amplifiers and High power audio circuits. It was originally manufactured by TOSHIBA in JAPAN and soon became one of the most popular power transistors. Its complementary transistor is the TTA1943 PNP transistor.
Its maximum ratings are: Collector to Emitter breakdown voltage is 230V, the collector current is 15A, and the current gain is 160.
TTC5200 vs 2SC5200: Compared
Given below are the differences between TTC5200 and 2SC5200 in the tabular form.
| Feature | TTC5200 | 2SC5200 |
| Cost | Cheaper | More expensive |
| Packaging | TO-3P | TO-264 |
| Manufacturer | Toshiba(Japan) | Anyone from Japan & China |
| DC Current Gain | 80 | 55 |
| Collector O/P Capacitance | 145 pF | 200 pF |
What are TT and 2S?
Only Toshiba holds the right to use TT, meaning no other company can use it. TT simply means devices with the TT abbreviation are diffused and assembled in Japan only. Whereas 2S devices like 2SC5200 can be manufactured in China and Japan.
The new TT devices use the latest Toshiba’s new manufacturing technologies such as diffusion, bonding, thermal conduction, and encapsulation.
TTC5200 vs 2SC5200: Packaging
The older 2SC5200 comes in TO-264(Toshiba) and TO-3P packages(ON Semiconductors) whereas the TTC5200(Toshiba) comes in TO-3P package only.
TTC5200 vs 2SC5200: Specs
The major difference between TTC5200 and 2SC5200 is of DC current gain and collector output capacitance. The minimum hFE of TTC5200 and 2SC5200 is 80 and 55 respectively. And COB of TTC5200 and 2SC5200 is 145 pF and 200 pF respectively.
TTC5200 Transistor Pinout
The pinout of both transistors is similar; starting from left: Base, Collector, and Emitter. The pinout of TTC5200 transistor is shown below.
| Pin Name | Description | |
| B | Base | Controls the transistor’s biasing, used to turn it on and off. |
| C | Collector | Current flows through the collector, usually connected to a load. |
| E | Emitter | Current comes out of transistor through the emitter, usually grounded. |
Applications of TTC5200 Transistor
Since TTC5200 is just a better replacement for 2SC5200, it can be used in any application where the latter is used. Some of the applications are listed below:
- Switch-mode power supplies (SMPS)
- Relays
- Used with its complementary transistor in a push-pull configuration
- Power supply
- Switching a load of high current rating
- Power amplifiers
- Inverters
- Converters
- Power control circuits
- DC to AC converters
