Overvoltage Protection for Negative Rail SLICs

Dual High Current Protectors in a Space Efficient Package

- 2 x 100 A 10/1000 Current Rating

- SMB03 Package (3-pin Modified SMB/DO-214AA)

Ion-Implanted Breakdown Region

- Precise and Stable Voltage

- Low Voltage Overshoot under Surge

These dual unidirectional thyristor devices protect SLICs and ISDN power feeds in central office, access and customer premises equipment

against overvoltages on the telecom line. Each protector section consists of a voltage-triggered unidirectional thyristor with an anti-parallel

diode. In the negative polarity, the thyristor allows signal voltages, without clipping, up to the maximum off-state voltage value, V

Figure 1. Voltages exceeding V

overvoltage, the thyristor switches into a low-voltage on-state condition, which diverts the current from the overvoltage through the thyristor.

When the diverted current falls below the holding current, I

overvoltages are limited by the conduction of the anti-parallel diode.

The TISP1xxxH3BJ is available in four voltages and has a 100 A 10/1000 current rating. These protectors have been designed particularly for

use in equipment that must meet the following standards and recommendations: GR-1089-CORE, TIA-968-A (replaces FCC Part 68), ITU-T

K.20, K.21 and K.45. Housed in a SMB03 package (3-pin modified SMB/DO-214AA), these parts are space efficient to replace protection

designs of 100 A 10/1000 or less which use multiple SMBs or a 6-pin SMT package.
