BIDIRECTIONAL THYRISTOR OVERVOLTAGE PROTECTORS

TISP4xxxM3BJ Overvoltage Protector Series

TISP4xxxM3BJ Overview

This TISP® device series protects central office, access and customer premise equipment against overvoltages on the telecom line. The TISP4xxxM3BJ is available in a wide range of voltages and has a medium current capability. These protectors have been specified mindful of the following standards and recommendations: GR-1089-CORE, FCC Part 68, UL1950, EN 60950, IEC 60950, ITU-T K.20, K.21 and K.45. The TISP4350M3BJ meets the FCC Part 68 “B” ringer voltage requirement (V_DRM = ±275 V) and survives the Type B impulse tests. For FCC Part 68 ADSL applications, the TISP4360H3BJ is recommended. The TISP4360H3BJ has an extra 15 V in working level (V_DRM = ±290 V) to avoid clipping the ADSL signal during ringing peaks. The TISP4xxxM3BJ series is housed in a surface mount SMB (DO-214AA) package.

Description

These devices are designed to limit overvoltages on the telephone line. Overvoltages are normally caused by a.c. power system or lightning flash disturbances which are induced or conducted on to the telephone line. A single device provides 2-point protection and is typically used for the protection of 2-wire telecommunication equipment (e.g. between the Ring and Tip wires for telephones and modems). Combinations of devices can be used for multi-point protection (e.g. 3-point protection between Ring, Tip and Ground).

The protector consists of a symmetrical voltage-triggered bidirectional thyristor. Overvoltages are initially clipped by breakdown clamping until the voltage rises to the breakover level, which causes the device to crowbar into a low-voltage on state. This low-voltage on state causes the current resulting from the overvoltage to be safely diverted through the device. The high crowbar holding current prevents d.c. latchup as the diverted current subsides.

The TISP4xxxM3BJ range consists of nineteen voltage variants to meet various maximum system voltage levels (58 V to 320 V). They are guaranteed to voltage limit and withstand the listed international lightning surges in both polarities. These medium (M) current protection devices are in a plastic package SMBJ (JEDEC DO-214AA with J-bend leads) and supplied in embossed tape reel pack. For alternative voltage and holding current values, consult the factory. For higher rated impulse currents in the SMB package, the 100 A 10/1000 TISP4xxxH3BJ series is available.

SMBJ (DO-214AA) Plastic Surface Mount Diode Package

This surface mount package consists of a circuit mounted on a lead frame and encapsulated within a plastic compound. The compound will withstand soldering temperature with no deformation, and circuit performance characteristics will remain stable when operated in high humidity conditions. Leads require no additional cleaning or processing when used in soldered assembly.
