TEA1708T/1J Description

Short technical summary and product information.

The NXP Semiconductors TEA1708T/1J is an automatic discharge integrated circuit specifically designed for X capacitors in AC-connected power supplies. It features a very low power consumption, typically 1 mW at 230 V AC, making it suitable for applications requiring low standby power.

Key features include an integrated 500 V clamping circuit that protects the IC during mains surges, eliminating the need for a metal-oxide varistor. The device offers very high differential surge protection, exceeding 6 kV when used with two 200 kΩ resistors. The X-capacitor discharge current is internally limited to 2.3 mA, and the discharge delay is externally adjustable using a low-voltage capacitor.

This IC is self-supplied, requiring no external bias. Its design helps reduce EMI while maintaining low standby power, enabling the use of high-value X-capacitors. The TEA1708T/1J is housed in an 8-SOIC package with a surface mount type, suitable for various power supply designs requiring efficient X-capacitor discharge and protection.

Applications include all AC-connected power supplies with X-capacitors greater than 100 nF that require low load standby power.
