STMicroelectronics CLP30-200B1RL

Overview

CLP30-200B1RL from STMicroelectronics is a dual bidirectional telecom line protection device combining overvoltage and overcurrent protection in a single SO-8 package. It delivers 40 A peak pulse current (5/310 µs), switches on at ≤290 V line-to-GND, and switches off at ≥150 mA holding current - enabling robust secondary protection for analog/ISDN line cards against lightning surges and AC mains transients per ITU-T K20/K21, GR-1089, and FCC Part 68.

For engineers reviewing the CLP30-200B1RL datasheet, CLP30-200B1RL pinout, CLP30-200B1RL application in telecom line cards, or CLP30-200B1RL equivalent for SLIC protection, this device provides voltage- and current-mode programmable protection with fail-safe short-circuit behavior, UL497B certification, and TRISIL™ technology validated for UL60950, IEC60950, and CSA C22.2 compliance.

Technical Context

The CLP30-200B1RL integrates dual independent protection channels (TIPL–GND/RINGL–GND and TIPS–GND/RINGS–GND) with internal >200 V overvoltage reference and external RSENSE-controlled overcurrent detection. Its OR-gated switching logic enables tripolar protection - responding to surges between TIP–GND, RING–GND, or TIP–RING - without requiring external biasing.

In ringing mode, it operates purely as a voltage-triggered device (VSWON ≤290 V); in speech mode, it functions as a current-triggered switch (ISWON adjustable from 220–380 mA via RSENSE = 3 Ω) coordinated with an external voltage reference (e.g., LCP1511D). The device maintains fail-safe short-circuit behavior during fault conditions and exhibits no aging-related degradation.

FAQ

What is the purpose of the four GND pins on CLP30-200B1RL?

The four GND pins (pins 2, 3, 6, 7) provide low-impedance parallel return paths for high di/dt surge currents during transient events. This layout minimizes inductive voltage spikes across the package, ensures uniform current sharing between protection channels, and improves thermal dissipation by distributing heat across multiple bond wires and leadframe segments - critical for sustaining 40 A (5/310 µs) pulses without latch-up.

Can CLP30-200B1RL be used without an external voltage reference in speech mode?

No. In speech mode, CLP30-200B1RL requires coordination with an external voltage reference (e.g., LCP1511D) to generate the current through RSENSE that triggers overcurrent protection. Without it, only the internal >200 V overvoltage threshold remains active - insufficient for low-voltage SLIC protection where surges must be detected below 100 V. The external reference defines the clamping level and enables precise ISWON programming.

How does CLP30-200B1RL achieve tripolar protection?

CLP30-200B1RL achieves tripolar protection by monitoring three independent voltage/current conditions: (1) TIPL–GND, (2) RINGL–GND, and (3) TIPL–RINGL (via internal OR logic between channels). Its dual-switch architecture (SW1/SW2) allows simultaneous conduction across any two terminals when either exceeds VSWON or ISWON thresholds - enabling protection against common-mode, differential-mode, and ground-referenced surges without additional components.

Is CLP30-200B1RL compliant with RoHS and REACH regulations?

Yes. CLP30-200B1RL is manufactured in STMicroelectronics' RoHS-compliant facilities and meets EU Directive 2011/65/EU (RoHS 2) and Regulation (EC) No. 1907/2006 (REACH), including SVHC screening. The SO-8 package uses lead-free matte tin plating, halogen-free epoxy, and cadmium-/mercury-/hexavalent chromium-free materials - verified in ST's official product change notices and material declarations dated August 2006 and later revisions.
