Nonrepetitive On-State Impulse vs. Waveform (IPPS) The TSPD or Thyristor Surge Protection Device are specialized silicon based overvoltage protectors, used to protect sensitive electronic circuits from damaging overvoltage transient surges caused by induced lightning and powercross conditions. The TSPD protects by switching to a low on state voltage when the specified protection voltage is exceeded. This is known as a "crowbar" effect. When an overvoltage occurs, the crowbar device changes from a high-impedance to a low-impedance state. This low-impedance state then offers a path to ground, shunting unwanted surges away from the sensitive circuits. This crowbar action defines the TSPD's two states of functionality: Open Circuit and Short Circuit. Open Circuit - The TSPD must remain transparent during normal circuit operation. The device looks like an open across the two wire line. Short Circuit - When a transient surge fault exceeds the TSPD protection voltage threshold, the devices switches on, and shorts the transient to ground, safely protecting the circuit. + I(OP) + Protected Equipment - STSPD looks like an open SCircuit operates normally V(OP) TSPD - Normal Circuit Operation I + (Fault) V(Fault) TSPD - + I(Fault) Protected Equipment - Operation during a Fault SFault voltage greater than Vbo occurs STSPD shorts fault to ground SAfter short duration events the O/V switches back to an open condition SWorst case (Fail/Safe) SO/V permanent short SEquipment protected Figure 4. Normal and Fault Conditions http://onsemi.com 3 NP-SDMC Series The electrical characteristics of the TSPD help the user to define the protection threshold for the circuit. During the open circuit condition the device must remain transparent; this is defined by the IDRM. The IDRM should be as low as possible. The typical value is less than 5 mA. The circuit operating voltage and protection voltage must be understood and considered during circuit design. The V(BO) is the guaranteed maximum voltage that the protected circuit will see, this is also known as the protection voltage. The VDRM is the guaranteed maximum voltage that will keep the TSPD in its normal open circuit state. The TSPD V(BO) is typically a 20-30% higher than the VDRM. Based on these characteristics it is critical to choose devices which have a VDRM higher than the normal circuit operating voltage, and a V(BO) which is less than the failure threshold of the protected equipment circuit. A low on-state voltage Vt allows the TSPD to conduct large amounts of surge current (500 A) in a small package size. Once a transient surge has passed and the operating voltage and currents have dropped to their normal level the TSPD changes back to its open circuit state. Transient Surge TSPD's are useful in helping designers meet safety and regulatory standards in Telecom equipment including GR-1089-CORE, ITU-K.20, ITU-K.21, ITU-K.45, FCC Part 68, UL1950, and EN 60950. ON Semiconductor offers a full range of these products in the NP series product line. DEVICE SELECTION When selecting a TSPD use the following key selection parameters. Off-State Voltage VDRM Choose a TSPD that has an Off-State Voltage greater than the normal system operating voltage. The protector should not operate under these conditions: Example: Vbat = 48 Vmax Vring = 150 Vrms = 150*1.414 = 212 V peak VDRM should be greater than the peak value of these two components: VDRM > 212 + 48 = 260 VDRM Breakover Voltage V(BO) Equipment Failure Threshold TSPD Protection Voltage Upper Limit Normal System Operating Voltage TSPD Transparent (open) TSPD Protection (short) TSPD Transparent (open) Volts Verify that the TSPD Breakover Voltage is a value less than the peak voltage rating of the circuit it is protecting. Example: Relay breakdown voltage, SLIC maximum voltage, or coupling capacitor maximum rated voltage. Peak Pulse Current Ipps Choose a Peak Pulse current value which will exceed the anticipated surge currents in testing. Hold Current (IH) Time Figure 5. Protection During a Transient Surge The Hold Current must be greater than the maximum system generated current. If it is not then the TSPD will remain in a shorted condition, even after a transient event has passed. http://onsemi.com 4 NP-SDMC Series TYPICAL APPLICATION Tip Testing: Tip - Ground Ring - Ground Tip and Ring to Ground Simultaneously Ring Surge Waveforms 100A NP3100SCMC 100A NP3100SCMC NP3100SDMC 200A Figure 6. * 200 A 10 x 1000 ms Needed for GR-1089 * Bottom Element in "Y" Configuration http://onsemi.com 5 NP-SDMC Series PACKAGE DIMENSIONS SMB CASE 403C-01 ISSUE A NOTES: 1.
