Littelfuse SPA Overview


SPA™ Lead-Free / Green Series

Designers of today's electronic devices have demanded more functionality with greater flexibility and higher levels of user interaction. These circumstances have helped in driving the development of nanometer chipsets along with a multitude of user interfaces or ports. The confluence of these two has made electronic devices more susceptible to ESD and required the need for a more robust solution.

ESD Standards:
MIL-STD-883, Method 3015
Historically, analog and digital designers have been required to have ESD protection "on-chip" to protect the IC during manufacturing. The most commonly used ESD standard in the manufacturing environment is the MIL-STD-883, Method 3015 and it's also referred to as the Human Body Model (HBM). This model discharges a 100pF capacitor through a 1500Ω resistor into the device under test. The table below points out the four test levels as defined in the standard.

HBM Level Contact Discharge (kV)
Peak Current (A)
1 ±0.5
0.33
2 ±1
0.67
3 ±2
1.33
4 ±4 2.67

The maximum level required for a typical IC had been ±2kV up until 2007, but today that level has been drastically reduced to ±0.5kV.Obviously, this has helped chip designers save valuable silicon area for more functionality, but in turn, it has made the IC much more susceptible to damage from ESD.

IEC61000-4-2
Conversely, equipment manufacturers have traditionally used an ESD standard defined by the IEC (International Electrotechnical Commission) for system or application level testing. This model uses a 150pF capacitor which is discharged through a 330Ω resistor. The table below displays the four test levels as defined in the standard.

IEC Level
Contact Discharge (kV)
Peak Current (A)
1 ±2 7.5
2 ±4 15
3 ±6 22.5
4 ±8 30

Most all manufacturers require that their equipment pass Level 4, or ±8kV, as a minimum, however, some are looking for increased reliability and require that their devices pass a much higher level like ±15kV or ±30kV.

Conclusions:
The system level ESD test defined by the IEC produces a substantial increase in peak current compared to the military standard. If an IC is rated for 0.5kVper the MIL-STD and the equipment manufacturer tests this same IC at8kV per the IEC specification, the chip will see nearly a 100 fold increase in peak current (i.e. 0.33A vs. 30A)!

Ultimately, hardware or board designers must add supplementary ESD devices to protect these sensitive chip sets from the high level ESD threats seen in the field.

SRV05
(SP3050)
The Littelfuse SRV05 (SP3050) Series integrates low capacitance rail-to-rail diodes with an additional zener diode to protect each I/O pin against ESD and high surge events. This robust device can safely absorb surge current per IEC 61000-4-5 (t P =8/20μs) without performance degradation and a minimum ±20kV ESD per IEC 61000-4-2. Their very low loading capacitance also makes them ideal for protecting high speed signal pins.

LC03-3.3 (SP03-3.3)
This new broadband protection device from Littelfuse provides overvoltage protection for applications such as 10/100/1000 BaseT Ethernet, T3/E3 DS3 interfaces, ADSL2+, and VDSL2+. The new LC03-3.3 (SP03-3.3) protectors combine the TVS diode element with a diode rectifier bridge to provide both longitudinal and differential protection in one package. This design innovation results in a capacitive loading characteristic that is log-linear with respect to the signal voltage across the device. This reduces intermodulation (IM) distortion caused by a typical solid-state protection solution.

SP2502L - NEW!
The Littelfuse SP2502L Series provides overvoltage protection for applications such as 10/100/1000 Base-T Ethernet and T3/E3 interfaces. This device has a low capacitance of only 5pF making it suitable for PHY side Ethernet protection and the capability to protect against both longitudinal and differential transients. Furthermore, the SP2502L is rated up to 100A (tp=2/10μs) making it suitable for line side protection as well against lightning transients as defined by GR-1089 (intra-building), ITU, YD/T, etc.

SP2504N - NEW!
The Littelfuse SP2504N Series integrates 4 channels of low capacitance diodes with an additional zener diode to protect sensitive I/O pins against lightning induced surge events and ESD. This robust device can safely absorb up to 20A per IEC61000-4-5 (tP=8/20μs) without performance degradation and a minimum ±30kV ESD per IEC61000-4-2 international standard. The low loading capacitance makes the SP2504N ideal for protecting high-speed signal pins.
