These diodes are clamping devices that limit voltage spikes by the low impedance avalanche breakdown of the P/N junction. CURRENT I IFPP + P-N - IF Vc BV VR VOLTAGE V IR VF - P-N + IPP Figure 1. Unidirectional V-I Curve The V-I curve shown in Figure 1 is similar to that of a Zener diode. TVS diodes are designed and characterized for transient voltage suppression, while Zener diodes are designed and specified for voltage regulation. 4 www.protekdevices.com A transient is clamped instantaneously and diverts the damaging current away from the protected device. Figure 2 shows a transient current being diverted to ground. Under normal operating conditions, the TVS presents a high impedance path to the protected circuit. During the transient event, the TVS achieves breakdown, then presents a low impedance path, which shunts the transient current through the TVS device. 8kV Positive and Negative Transient VOUT VIN I1 I2 12V Positive and 0.6V Negative Clamped Waveform for Unidirectional Device Figure 2. Unidirectional Device (Asymmetrical Clamping) WHY TVS PROTEK’TION The ESD association has estimated that the average loss of product due to user-generated ESD at 27% to 33%. This costs the industry billions of dollars in losses. Transient voltage suppressors prevent system and component failure caused by ESD, EFT and other transients. TVS DEVICE SELECTION A TVS device with the proper characteristics for a given application should: • Prevent system/component damage • Optimize circuit performance The following key parameters should be considered when selecting a TVS device • Stand-Off Voltage (VWM) - the maximum continuous dc or peak voltage which may be applied over the standard operating temperature range. VWM is normally 10% below the breakdown voltage (VBR). • Breakdown Voltage (VBR) - the voltage measured across the device at a specified pulsed dc current (IT or IBR) on the V/I characteristic curve at or near to where the breakdown (avalanche) occurs. Also known as the voltage across the device in the breakdown region prior to the switching point at a specified breakdown current (IBR). • Leakage Current (ID) - the maximum current that flows through the device at the rated stand-off voltage (VWM) for a specified temperature. Also known as Reverse Leakage Current (IR). • Capacitance (C) - this parameter is associated with high data rate applications and is measured at a specific frequency and bias. High capacitance degrades signals. • Forward Voltage (VF) - the voltage across the device in the forward conducting state at a specified current IF. • Clamping Voltage (VC) - the peak voltage measured across the device during the application of a pulse current (IPP) for a specified waveform. • Peak Pulse Current (IPP) - the maximum current handling capability for a given pulse duration (td). The current capability is referenced to a specific waveshape (i.e., 8/20µs, 10/1000µs) and is not constant over time. • Peak Pulse Power (PPP) - the maximum clamping voltage (VC) multiplied by the maximum peak pulse current (IPP), where the maximum clamping voltage is considered independent of time. 5 www.protekdevices.com ELECTRICAL CHARACTERISTICS PER LINE @ 25°C Unless Otherwise Specified PART NUMBER (Note 1) RATED STAND-OFF VOLTAGE MINIMUM BREAKDOWN VOLTAGE MAXIMUM CLAMPING VOLTAGE VWM VOLTS @ 1mA V(BR) VOLTS @ IP = 1A VC VOLTS PAM01SC7905C 5.0 6.0 PAM02SD2312C 12.0 †PAM03SD2303CI MAXIMUM CLAMPING VOLTAGE (Note 2) MAXIMUM LEAKAGE CURRENT TYPICAL CAPACITANCE (Note 2) PACKAGE @ 8/20µs VC @ IPP @VWM ID µA @0V, 1MHz C pF - 16.0V @ 10.0A 1.0 1.5 SC-79 13.3 19.0 - 1.0 3 SOD-323 3.0 4.0 7.0 - 5.0 0.6 SOD-323 †PAM04ST430502 5.0 6.0 9.8 20.0V @ 10.0A 1.0 0.6* SOT-543 PAM05SC700504F 5.0 6.0 15.0 - 3.0 1.9* SC70-6L †PAM06SC7905S 4.7 5.7 - - 0.5 @ 3.5V 30* SC-79 †PAM07DFK2324 24.0 26.7 - 43.0V @ 69.8A 3 - DFN-2-3KW †PAM08SD2305C 5.0 6.0 9.8 - 10 175 SOD-323 †PAM08SD2324C 24.0 26.7 43.0 - 1.0 40 SOD-323 †PAM09SD2305HP 5.0 6.0 - 15.0V @ 72.0A 20 800 SOD-323 PAM10ST2315C 15.0 16.7 24.0 30.0V @ 17.0A 1.0 60 SOT-23 †PAM10ST2324C 24.0 26.7 43.0 49.0V @ 12.0A 1.0 63 SOT-23 †PAM11SO803 3.0 2.8 - [email protected] 2.0 25** SO-8 PAM12SO824 2.8 3.0 [email protected] 1.0 3 SO-8 PAM13ST2305 5.0 6.0 12.0 - 5.0 3.5 SOT-23-6 †PAM14ST6305LCC 5.0 6.0 [email protected] - 1.0 9 SOT-563 PAM15ST4305 5.0 6.0 9.8 20.0V @ 28.0A 5.0 10 SOT-143 †PAM16AL30A 30.0 33.3 - 50.7V @ 296.0A*** 15.0 - AXIAL PAM17DF2L05C 4.7 5.7 - - 1.0 15 DFN-2-0402 †PAM18DF2L0521 5.0 6.0 14.0 20.0V @ 4.0A 1.0 0.4 DFN-2-0402 PAM19DF2L0521P 5.0 6.0 20.0 - 1.0 0.6 DFN-2-402 †PAM20ST6305 5.0 6.0 - 12.0V @ 9.0A 1.0 40 SOT-563 PAM21SC790501H 5.0 6.0 9.8V @ 5.0A - 5.0 120 SC-79 †PAM25DF25K33 33.0 36.8 - 53.3V @ 94.0A 8.0 - DFN-2-5KW †PAM25DF25K36 36.0 40.2 - 58.1V @ 86.0A 8.0 - DFN-2-5KW NOTES 1. †AEC-Q101 qualification pending. 2. *Values represent maximum capacitance. **Measured between I/O pins and ground (pin 1 to 2). ***10/1000µs Waveshape.
