PMT4120/TR7: Application Field and Working Principle
PMT4120/TR7 is a type of single zener diode which operates as an electrical component used to regulate voltage. It\'s a heavily doped PN junction diode having a highly defined reverse breakdown voltage value and an exceptionally well behaved electrical characteristic in a very small physical size. It\'s commonly used in voltage regulator circuits, DC-DC converters, battery powered applications and transient suppression applications.
Package & Pinout
PMT4120/TR7 has its package available in a variety of pinouts for different applications and it comes in a SOD-123FL (Small Outline Diode with 0.123 inches between its longest two pins). It has zero leaded package and an ideally low reverse leakage current.
Absolute Maximum Ratings
The PMT4120/TR7 has its absolute maximum ratings include Reverse Leakage Current at 5 uA (or 1.0 mA Reverse Voltage at Vr = 5 V); Operating Junction Temperature of -40C to +8C; Storage Temperature Range of -40C to +12C; Thermal Resistance Junction To Ambient of 356 FT (113.9 C/W).
Features
PMT4120/TR7 offers a low profile, low profile zener, low dielectric strength, corrosion resistance and a variety of issues in designing small, efficient circuit applications. It has an integrated thermal resistance of 25 to 50°C/W, maximum power dissipation of 500mW and a package size of 2x3x0.6 mm.
Nominal Operating Conditions
The PMT4120/TR7 series has been nominally rated to operate for at a Reverse Voltage of 5.1 V (or 4.0 to 5.1 V), Current of IZT of 20 mA with Maximum Zener impedance of ZZT maximum of 1.0 Ohm, or ZZK maximum of 0.3 Ohm at VZK. Male and female pins, respectively. Panels and terminals have different dimensions depending on the specific application.
Applications
The PMT4120/TR7 is specially designed for low voltage applications, such as voltage regulator for DC-DC converters, battery powered applications, transient suppressors and voltage regulator circuits, audio applications such as amplifier/mixer circuit, switches, and microphone applications. Moreover, this series is found to be compatible with lead-free soldering processes.
Working Principle
PMT4120/TR7 behaves similarly to other zeners, and its working principle is based on the heavier doping of a PN junction diode. The PN junction diode is modified to have a higher zener voltage and a relatively low zener impedance, as each PMT4120/TR7 is highly and differently stored, ranging from 4V to 5.1 V. When a reverse voltage is applied to a PN junction diode, the electrons from the n-side of the junction overcome the voltage and conduct from the n-side to p-side and forming a reverse current which flow unchecked. The adjustable series resistor use for the circuit can then be fixed for each different application.
Conclusion
The single zener diode PMT4120/TR7 is a small, efficient and cost-effective voltage regulating device for low voltage applications like DC-DC converters, battery powered applications and transient suppression. Its integrated thermal resistance, maximum power dissipation and its small package sizes make it ideal for small, efficient circuit applications. It is a highly defined reverse breakdown voltage, low reverse leakage current and apart from good electrical behavior, it is also highly compatible with lead-free soldering processes.
