TVS diodes are an important component for enhancing electronic circuit protection. The SMLJ200AE3/TR13 is a surface-mount 500 W peak pulse power unidirectional TVS diode that provides circuit protection from hazardous electrostatic discharges (ESDs). It can also be used in order to protect against spikes, surges, and lightning strikes.

Construction and Design

The SMLJ200AE3/TR13 diode is constructed in a 2-pin SMD configuration that is made up of an anode and a cathode. The maximum peak pulse power rating of the diode is 500 watts and its reverse polarity breakdown voltage is 200 V. The junction-to-ambient thermal resistance is 5.4 K/W and it has an operating temperature range from - 55 to 125°C. It can be soldered to a printed circuit board with either wave or reflow soldering techniques.

Application Fields

The SMLJ200AE3/TR13 diode is typically used in applications that require a high level of protection from ESDs, surges, and other voltage transients. It is commonly used in a variety of industries such as automotive, industrial, medical, and consumer electronics. It can be used for ESD protection on printed circuit boards, communication ports, and data lines. It can also be used in LCD backlighting and other sensitive analog circuits.

Working Principle

When the SMLJ200AE3/TR13 diode is exposed to an electrostatic discharge or other voltage transient, it will quickly clamp the voltage down to a safe level. This is achieved by the diode\'s unique ability to quickly switch on and short out any excess voltage. The diode will then quickly dissipate the excess voltage and protect the circuit from damage.

The diode is designed to withstand extreme voltage transients up to 500 W. This is achieved by its high surge current rating and low clamping voltage. The low clamping voltage ensures that the diode will not cause any damage to the circuit components by clamping the voltage too low. The current rating also ensures that the diode can handle higher voltage transients without burning out.

Conclusion

The SMLJ200AE3/TR13 diode is a surface-mount 500 W peak pulse power unidirectional TVS diode that provides circuit protection from hazardous electrostatic discharges (ESDs). It is typically used in applications that require a high level of protection from ESDs, surges, and other voltage transients. When exposed to an ESD or other voltage transient, the diode will quickly clamp the voltage down to a safe level and dissipate any excess voltage, thus ensuring the circuit is protected from damage.
