TEA1708T - GreenChip X capacitor discharger

General Description

The TEA1708 is an automatic discharge IC for X capacitors with a low power consumption (typically 1 mW at 230 V (AC).

A 500 V clamping circuit is integrated, protecting the IC during mains surges.

Key Features

  • 1 mW power consumption at 230 V (AC).
  • Integrated 500 V clamp; no metal oxide varistor required to protect the IC.
  • Self-Supplied, no external bias required.
  • Discharge current internally limited.
  • Adjustable discharge delay.
  • Very high differential surge: 6 kV with two 200 kΩ resistors.
  • Easier.

TEA1708T GreenChip X capacitor discharge IC Rev. 1.1 — 6 April 2020 Product data sheet 1 General description The TEA1708 is an automatic discharge IC for X capacitors with a low power consumption (typically 1 mW at 230 V (AC). A 500 V clamping circuit is integrated, protecting the IC during mains surges. In a typical application with only two 200 kΩ resistors, the maximum differential mode mains surge voltage allowed exceeds 6 kV. A metal-oxide varistor is not required to protect the IC. The X-capacitor discharge current is internally limited to 2.3 mA. The discharge delay timer is set externally using a low-voltage capacitor. To reduce EMI while retaining the low standby power, the very low power consumption with a high discharge current enables the use of a high value X-capacitor.
