SVC220-PM-TB-E

Overview

The SVC220-PM-TB-E is a silicon avalanche surge protector manufactured by onsemi, designed for high-energy transient suppression. It features a DO-15 axial leaded plastic package and operates with a maximum repetitive peak off-state voltage of 200 V. The device has a minimum breakdown voltage of 220 V and a maximum holding current of 180 mA. It supports a non-repetitive peak forward surge current of 20 A at 60 Hz for one half-cycle. The component is rated for operation within a junction temperature range of -40 °C to +175 °C and is compliant with RoHS standards.

Feature Summary

• Engineered for robust protection against high-energy electrical surges in power circuits
• Utilizes silicon avalanche technology for reliable clamping performance under transient conditions
• Constructed in a DO-15 axial leaded package suitable for through-hole mounting applications

Applications

• Surge protection for AC mains input stages in industrial equipment
• Transient voltage suppression in motor drive systems
• Protection points in power supply input filtering networks

Procurement Notes

Verify the manufacturer marking and date code on the physical component to confirm authenticity. Ensure the ordering suffix matches the specific tape and reel or bulk packaging requirements. Confirm that the RoHS compliance status aligns with current environmental regulations for the intended deployment region.

Selection Notes

Select this component when circuit design requires handling high-energy transients exceeding standard TVS diode capabilities. Evaluate the peak pulse current rating against expected lightning or switching surge profiles. Ensure the standoff voltage exceeds the maximum continuous operating voltage of the protected line to prevent unintended triggering during normal operation.

Part Context

This part belongs to the SVC series of silicon surge protectors from onsemi. These devices are distinct from low-power transient voltage suppressors by their ability to absorb significantly higher energy levels. The series is commonly used in heavy-duty electronics where robust overvoltage protection is critical for system reliability.

Replacement Considerations

Cross-reference with Littelfuse T10A220E or similar DO-15 silicon surge protectors. Verify that substitute parts match the 200 V DC blocking voltage, 220 V breakdown threshold, and 20 A surge current capacity. Confirm package compatibility and thermal characteristics before implementation.
