2N5063 APM PBFREE

Overview

The 2N5063 APM PBFREE is a silicon-controlled rectifier (SCR) manufactured by Central Semiconductor Corp. It features a maximum RMS on-state current of 0.8 amperes and supports blocking voltages ranging from 15 to 200 volts. The device utilizes a sensitive gate structure for reliable triggering. It is housed in a TO-92-3 (TO-226AA) through-hole package with molded plastic construction. Key electrical ratings include a peak forward off-state voltage of 200 V, a non-repetitive peak forward surge current of 10 amperes, and a holding current of 4 mA. The component operates within a junction temperature range of -65°C to +150°C.

Feature Summary

• Sensitive gate architecture ensures consistent turn-on characteristics at low gate trigger currents.
• Robust thermal management capabilities supported by a wide operating junction temperature range up to 150°C.
• Compact TO-92-3 molded plastic package designed for standard through-hole PCB mounting applications.

Applications

• Low-power AC switching circuits requiring precise control.
• Battery charging systems utilizing SCR-based regulation.
• Lighting control modules for dimming or switching functions.
• General-purpose power control applications within the specified voltage and current limits.

Procurement Notes

Verify the specific voltage variant required, as the 2N5063 series encompasses multiple blocking voltage options including 15V, 30V, 50V, 75V, 100V, 150V, and 200V. Confirm that the selected part matches the circuit's peak reverse voltage requirements. Ensure the procurement specification explicitly states the desired voltage rating to avoid confusion with other members of the 2N506x family. Check RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a compact, low-current SCR is needed for sensitive gate triggering applications. The 0.8A RMS rating suits light loads where larger packages are impractical. Consider the TO-92-3 package constraints regarding heat dissipation; ensure adequate PCB copper area or heatsinking if continuous operation approaches the thermal limits. Verify that the gate trigger current requirements align with the driving circuit's output capabilities.

Part Context

The 2N5063 belongs to Central Semiconductor's line of sensitive gate silicon-controlled rectifiers. This series is characterized by its ability to switch moderate currents using minimal gate drive power. The device shares the same physical footprint and general electrical profile as other variants in the 2N506x family, differing primarily in their maximum repetitive peak forward off-state voltage ratings. It serves as a cost-effective solution for small-scale power control tasks.

Replacement Considerations

Direct replacements must match the 0.8A RMS current rating, sensitive gate technology, and TO-92-3 package. Equivalent parts from other manufacturers should be verified for identical pinout configuration and comparable holding/latching currents. Generic SCRs with higher current ratings may fit physically but could exhibit different triggering characteristics unsuitable for sensitive gate circuits.
