BT169H/L01EP

Scrs Overview

The BT169H/L01EP is a Silicon Controlled Rectifier (SCR) manufactured by WeEn Semiconductors. It features a rated repetitive off-state voltage of 800 V and an on-state RMS current of 800 mA. The device utilizes a sensitive gate architecture with a maximum gate trigger voltage of 500 mV and a gate trigger current of 50 uA. It operates within a junction temperature range up to +125 C and is housed in a SOT-54-3 (TO-92) through-hole package.

Scrs Feature Summary

• Sensitive gate design for low power triggering
• Planar passivated construction for voltage ruggedness
• High voltage capability suitable for robust applications

Scrs Applications

• Earth leakage circuit breakers or Ground Fault Circuit Interrupters (GFCI)
• Ignition circuits
• Low power latching circuits
• Protection circuits for lighting ballasts
• Protection circuits for Switched Mode Power Supplies

Scrs Procurement Notes

Verify the specific suffix 'L01EP' against official WeSemiconductor documentation to confirm exact marking, tape-and-reel specifications, and compliance status. Ensure the ordering part number matches the required packaging quantity and RoHS/REACH declarations before finalizing procurement orders.

Scrs Selection Notes

Select this component when an 800 V SCR with sensitive gate characteristics is required for high-voltage protection or latching applications. The TO-92 package suits through-hole designs where space allows. Confirm that the 800 mA RMS current rating meets the load requirements and that the 500 mV gate trigger voltage aligns with the control circuit capabilities.

Scrs Part Context

This device belongs to the BT169 series of Silicon Controlled Rectifiers from WeEn Semiconductors. The series includes variants with different voltage ratings such as 200 V, 400 V, 600 V, and 800 V. The BT169H specifically denotes the 800 V rating within this family of planar passivated thyristors designed for general-purpose switching and protection.

Scrs Replacement Considerations

Compatible substitutes include other 800 V SCRs in TO-92 packages with similar sensitive gate characteristics, such as the BT169H/01U or BT169H,112. Verify pinout compatibility and electrical parameters like holding current and non-repetitive peak current before substitution.
