BT152X-800R,127

Scrs Overview

The BT152X-800R,127 is a planar passivated Silicon Controlled Rectifier (SCR) manufactured by WeEn Semiconductors. It is housed in a SOT186A (TO-220F) full pack plastic package designed for through-hole mounting. The device features an 800 V repetitive peak reverse voltage and supports a continuous on-state current of 13 A with an RMS current capability of 20 A. It withstands a non-repetitive surge current of 200 A and offers a high dV/dt rating of 200 V/µs. The maximum junction temperature is rated at 125 °C.

Scrs Selection Notes

Select this component when high thermal cycling endurance and significant inrush current tolerance are required. The TO-220F full pack package provides superior heat dissipation compared to standard packages. Ensure the circuit design accommodates the 125 °C maximum junction temperature limit and the 200 A surge current rating during turn-on events.

Scrs Part Context

This part belongs to the BT152 series of planar passivated SCRs from WeEn Semiconductors. It shares functional similarities with the BT152-800R but utilizes the TO-220F full pack package instead of the standard TO-220AB. This packaging variant is specifically engineered to enhance thermal stability and mechanical resilience under repeated thermal stress conditions.

Scrs Replacement Considerations

The BT152-800R,127 is a related alternative within the same family but uses a standard TO-220 package rather than the TO-220F full pack. Verify that the thermal management requirements of the application can be met by the standard package if substituting.
