Customized TISP® Pairs For Solid State Relay (LCAS) Protection 15 V, 30 V & 40 V TISP® To Protect High-frequency Digital Telecom Lines Features Our new TISP4125x3BJ & TISP4219x3BJ are coordinated pairs of protectors designed to protect Solid State Relays. Solid State Relays are used in line card applications where conventional electro-mechanical relays are not suitable, and may also be referred to as LCAS (Line Card Access Switches). LCAS have more precise protection needs than electro-mechanical relays, requiring reduced voltage limiting to protect between switch terminals and from the terminals to ground. These surface mount SMB packaged devices are designed to be used as a protector pair, protecting the line side of the LCAS for battery backed, ground backed and balanced ringing configurations. These two separate devices need to have different protection voltages to allow the system and ringing signal to pass below the protection level, while minimizing stress on the SLIC. Features We are proud to announce six low-voltage TISP® telecom protectors, developed using our new low-voltage Thyristor process, which allows us to produce devices with lower & more precisely controlled voltages than ever before. Each device provides 2-point protection and is typically used for the protection of transformer windings and low-voltage electronics. • Designed to Protect Solid State Relays (LCAS) - e.g. Agere (Lucent) or Clare ‘7581, ’7582, ‘7583 - Intersil™ ISL5571A • Customized voltages for LCAS TSP Device - Ground-backed ringing 10/1000 C V (V) V (V) TISP4015L1BJR 8 15 30 23 TISP4030L1BJR 15 30 30 22 TISP4040L1BJR 25 40 30 18 TISP4015H1BJR 8 15 100 65 TISP4030H1BJR 15 30 100 50 TISP4040H1BJR 25 40 100 47 DRM (BO) off (A) (pF) (87 VRMS) - Battery-backed ringing (101 VRMS) • 50 A & 100 A 10/1000 surge ratings available • Detailed applications information At room temperature, a typical LCAS has a voltage rating of 320 V between the switch terminals, and from the switch terminals to the logic control circuitry. The TISP4219x3BJ protects to a maximum of 219 V from the Ring line to ground, and the TISP4215x3BJ protects to a maximum of 125 V on the Tip line while still allowing the battery and ringing signals to pass. During normal system operation, this combination of TISP® devices allows system levels of ±100 V on the Tip line and ±180 V on the Ring line to pass without clipping. These devices are available with either 50 A "M" rated or 100 A "H" rated 10/1000 surge guarantees.

Negative overvoltages are initially clipped close to the SLIC negative supply rail value. If sufficient current is available from the overvoltage, then the protection will crowbar into a low-voltage on-state condition. As the current subsides, the high crowbar holding current prevents DC latch up. If you are using a high-voltage ringing SLIC such as the Legerity™ 79R241 or the Infineon PEB series, the TISP61089B is the ideal overvoltage protection solution. The TISPPBL3 is matched to the requirements of the Ericsson Microelectronics PBL series SLICs. We invite you to request your free samples and datasheets with the prepaid card enclosed.

TIP RING TISP® Telecom Overvoltage Protectors • Low voltage overshoot under ® LCAS Terminal 100 high-voltage ringing SLICs The protector’s gate terminal is typically connected to the negative supply rail of the SLIC. This references the protection voltage to the negative supply voltage. The protector tracks the negative supply voltage to minimize overvoltage stress on the SLIC. 4B04B-524-400 100 180 - T1/E1 • Programmable to –170 V for RX2 If you interested in providing optimum protection for your LCAS, we invite you to request your free datasheet and coordinated pair of samples with the prepaid card enclosed. 10/1000 Surge Rating (A) • Applications include: These devices feature ultra low capacitance that is guaranteed at all anticipated system levels, making them ideal for high data-rate digital applications.

This extends equipment life and allows compliance with UL 1950 / UL 60950 (also known as IEC 60950, EN 60950 and CSA 22.2 No.950). The TISP8200M and TISP8201M are a complementary pair of programmable protectors, designed to protect ringing SLICs with dualpolarity supply rails. Both devices feature two high-gain, robust transistor buffers and reverse polarity blocking thyristor sections. The protection function has been deliberately split into positive and negative devices to minimize voltages under +ve and –ve surges. Both devices are supplied in 8-pin small outline packages. • Designed for Surge Bar applications • Insulation overvoltage to assist compliance with UL 1950 / The ‘950 family of standards have certain requirements for equipment with incoming lines of telecom network voltage (TNV). Any protector from a TNV conductor to protective ground must have a voltage rating which is at least 1.6 times the equipment rated supply voltage. The intent is to prevent the possibility of the a.c. mains supply voltage from feeding into the telecommunication network and creating a safety hazard. International and European equipment usually have a maximum rated voltage of 230, 240 or 250 Vrms. Multiplying 250 V by 1.6 gives a protector VDRM of 400 V. The TISP4600F3 will protect a single line to ground, while the dual-configuration TISP3600F3 allows protection of two lines to ground.
