BT151S-500R,118

Scrs Overview

The BT151S-500R,118 is a planar passivated Silicon Controlled Rectifier (SCR) manufactured by WeEn Semiconductors. It is housed in a SOT428 (DPAK/TO-252) surface-mountable plastic package designed for high bidirectional blocking voltage and thermal cycling performance. Key electrical parameters include a repetitive peak off-state voltage of 500 V, an on-state RMS current of 12 A, and a non-repetitive peak surge current of 120 A. The device features a maximum DC gate trigger current of 15 mA, a holding current of 20 mA, and operates within a junction temperature range of -40°C to +125°C.

Scrs Feature Summary

• Planar passivated silicon construction ensures robust bidirectional blocking voltage capability.
• Surface-mount DPAK package design facilitates efficient thermal cycling performance.
• High surge current capability supports demanding industrial switching applications.

Scrs Applications

• Motor control systems
• Industrial heating controls
• Static switch circuits

Scrs Procurement Notes

Verify the specific orderable part number suffix against official manufacturer documentation to ensure correct packaging configuration. Confirm that the requested component matches the SOT428 (DPAK) surface-mount package type. Cross-reference the 12NC code with the supplier's catalog to validate the exact variant. Ensure compliance with RoHS and lead-free requirements as specified in the technical datasheet before finalizing procurement orders.

Scrs Selection Notes

Select this component when a surface-mount SCR solution is required for applications needing 500V blocking voltage and 12A continuous current handling. The DPAK package offers a compact footprint suitable for automated assembly processes. Consider the 15mA gate trigger requirement for driver circuit compatibility. Evaluate thermal management needs based on the 120A surge rating and operating temperature limits.

Scrs Part Context

This device belongs to the BT151 series of Silicon Controlled Rectors produced by WeEn Semiconductors, a joint venture involving NXP Semiconductors. The series includes various voltage ratings and package options, such as through-hole TO-220AB and surface-mount variants like the BT151X.
