TCM1030 General Description

The TCM1030 and TCM1050 dual transient-voltage suppressors are designed specifically for telephone line card protection against lightning and transients (voltage transients) induced by ac lines. One of the TIP terminals (pin 1 or 8) and one of the RING terminals (pin 4 or 5) are connected to the tip and ring circuits of a SLIC (subscriber-line interface circuit). The battery feed connections between the SLIC and the subscriber line are from the remaining TIP (pin 1 or 8) and RING (pin 4 or 5) through the TCM1030 or the TCM1050 to the tip and ring lines. Transients are suppressed between tip and ground, and ring and ground.

Positive transients are clamped by diodes D1 and D2. Negative transients that are more negative than VS cause the SCRs, Q1 and Q2, to crowbar. The high holding current of the SCRs prevent dc latchup as the transient subsides.

The TCM1030 and TCM1050 are characterized for operation from 40 to 85.

NOTE 1: The notation 10/1000 refers to a waveshape having t_r = 10 ms and t_w = 1000 ms ending at 50% of the peak value. The notation 10/160 is t_r = 10 ms and t_w = 160 ms. The notation 2/10 is t_r = 2 ms and t_w = 10 ms.

† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES: 1 The notation 10/1000 refers to a waveshape having t_r = 10 ms and t_w = 1000 ms ending at 50% of the peak value. The notation 10/160 is t_r = 10 ms and t_w = 160 ms. The notation 2/10 is t_r = 2 ms and t_w = 10 ms.

2. This value applies when the case temperature is at or below 85. The surge current may be repeated after the device has returned to thermal equilibrium.
