**SMP100LC**
Trisil™ for telecom equipment protection
**==> picture [61 x 39] intentionally omitted <==**
## **Features**
- Bidirectional crowbar protection
- Voltage range from 8 V to 400 V
- Low capacitance from 20 pF to 45 pF @ 2 V
- Low leakage current: IR = 2 µA max
- Holding current: IH = 150 mA min.
- Repetitive peak pulse current: IPP = 100 A (10/1000 µs)
## **Benefits**
- Trisils are not subject to ageing and provide a fail safe mode in short circuit for better protection.
- Helps equipment meet main standards such as UL60950, IEC 950 / CSA C22.2 and UL1459.
- Epoxy meets UL94, V0.
- Package is JEDEC registered (DO-214AA).

## **Description**
The SMP100LC is a series of low capacitance transient surge arrestors designed for the protection of high data rate communication equipment. The low capacitance of the devices avoids any distortion of the signal and is compatible with digital transmission line cards (xDSL, ISDN...).
SMP100LC series tested and confirmed compatible with Cooper Bussmann Telecom Circuit Protector TCP 1.25A.
The SMP100LC-xxx with the fuse TCP1.25A or TCP2A is compliant with Telcordia GR1089 (lightning and AC power fault tests), ITU-T K20/K21 (lightning and AC power fault tests), TIA/EIA-IS-968 (formerly FCC Part 68 lightning tests), and UL60950 (AC power fault tests). The use of the TCP1.25A allows the SMP100LC-xxx to be safe for the 2nd level (B criteria) AC power fault tests.

## **2 Application information**
In wire line applications, analog or digital, both central office and subscriber sides have to be protected. This function is assumed by a combined series / parallel protection stage.

Protection stage Protection stage
**----- End of picture text -----**
In such a stage, parallel function is assumed by one or several Trisil, and is used to protect against short duration surge (lightning). During this kind of surges the Trisil limits the voltage across the device to be protected at its break over value and then fires. The fuse assumes the series function, and is used to protect the module against long duration or very high current mains disturbances (50/60Hz). It acts by safe circuit opening. Lightning surge and mains disturbance surges are defined by standards like GR1089, TIA/EIA IS-968, ITU-T K20.
