Applications  
bias required. See Figures 1(a) & 1(b).  
Both of these uses will provide ESD  
protection at the limiting value. For  
adjustable limiting and detection,  
the bias should be applied as shown  
in Figure 1(c). Adjustable limiting is  
achieved by setting the A pin to a DC  
voltage ~0.7 volts higher than the  
Assembly techniques  
The TC231 can be used as a protection  
circuit for ESD and DC transients, as a  
Reverse Power Protection (RPP) device,  
or as an RF limiter with optional power  
detection.  
The 1GC1-4235 is designed for surgace  
mount on a printed surface board using  
standard SMTtechniques and wave  
solder.  
Well-designed PCB transitions and via  
structures are essential for obtaining

are ESD sensitive. ESD preventive  
measures must be employed in all  
aspects of handling and assembly.  
Diode ESD precautions, handling  
considerations, and soldering methods  
are critcial factores in successful diode  
performance and reliability.  
If the voltage is not forced, the  
capacitor will function as a peak  
detector.  
As an ESD protection device, the  
TC231 can protect ESD sensitive  
components. The degree of protection  
depends on the protected components  
characteristics. ESD damage level for  
the TC231 by itself is around 2400V  
using the human body model.  
Biasing  
None required for traditional operation.  
For adjustable limiting, the bias voltage  
will set the limiting value as described  
under Operation.  
Operation  
The TC231 has three primary modes  
of operation. 10 dBm and 18 dBm
