P3100EBLRP2

The P3100EBLRP2 is a SIDACtor protection thyristor manufactured by Littelfuse Inc. It is designed for overvoltage protection in baseband equipment such as modems, line cards, CPE, and DSL, enabling compliance with global regulatory standards. The device offers a minimum off-state voltage (Vdrm) of 275 V and a maximum switching voltage (Vs) of 350 V at 100 V/µs. It features a minimum holding current (Ih) of 150 mA and a maximum switching current (Is) of 800 mA. The on-state current (It) is rated at 2.2 A maximum with an on-state voltage (Vt) of 4 V maximum at 2.2 A. The capacitance is 45 pF maximum at 1 MHz with 2 V bias. The peak surge current is 80 A typical.

The thyristor is housed in a through-hole TO-226-2/TO-92-2 (TO-226AC) package with formed leads, and the supplier device package is TO-92-2. It is a single-element device. The P3100EBLRP2 is RoHS3 compliant, has a moisture sensitivity level (MSL) of 1 (unlimited), and is REACH unaffected. The part is designed for low voltage overshoot, low on-state voltage, and does not degrade surge capability after multiple surge events within limits. It fails short circuit when surged in excess of ratings.

Applications include baseband protection in voice-DS1 interfaces, and it is suitable for use in equipment requiring compliance with TIA-968-A, TIA-968-B, ITU K.20/21, GR 1089, and IEC 61000-4-5 standards.
