TVS (Transient Voltage Suppressor) diodes are devices designed to protect components and circuits from voltage transients caused by lightning strikes, ESD (electro-static discharge) or over-voltage conditions. The TPC15AHM3_A/I is a bidirectional unidirectional overvoltage protection diode from Diodes Incorporation. It has an unidirectional breakdown voltage of 15V, reverse stand-off voltage of 5V and low clamping voltage. The device has an ESD protection rating of 12kV.

TPC15AHM3_A/I Application Fields

The TPC15AHM3_A/I is specifically designed to protect circuits against transients caused by electro-static discharge (ESD), lightning strikes, or over voltage conditions. It is widely used in automotive, consumer electronics, communication, industrial, and portable applications. These applications can include computers, peripherals such as keyboards and mice, cell phones, tablets, monitors, and gaming consoles. It can also be used in medical and telecom applications. The device can be connected to ground or another power source to provide more comprehensive protection.

TPC15AHM3_A/I Working Principle

The operation of the TPC15AHM3_A/I is based on Zener diode action. When a voltage transient rises to a certain level, the diode begins to conduct, thus diverting the excess voltage away from the circuitry. The device modulates the transient to a more manageable level and clamps it at a safe voltage level. The device is rated to protect against transients up to 12kV ESD rating and has an unidirectional breakdown voltage of 15V and reverse standoff voltage of 5V.

The TPC15AHM3_A/I is especially suitable for low-power applications such as handheld, portable and consumer electronics. It is a RoHS compliant device, has an operating temperature range of -55° to +125°C, and a storage temperature range of -55° to +150°C. It is available in a lead-free SOD923 package and has a rated power dissipation of 500mW.

Conclusion

The TPC15AHM3_A/I is a TVS diode designed to protect sensitive components against voltage transients caused by ESD, lightning, and over-voltage conditions. It has an ESD protection rating of 12kV and an unidirectional breakdown voltage of 15V. The device can be connected to ground or another power source for improved protection. It is widely used in automotive, consumer electronics, communication, medical, and industrial applications.
