About the Product

This pack contains five genuine 1N4004 rectifier diodes, ideal as replacement or spare diodes for the BLOCKsignalling PTS1 Automatic DC Shuttle with Points Control. These are the same type of diode specified for creating the insulated stopping sections required for automatic shuttle operation.

The 1N4004 is a reliable, general-purpose rectifier diode featuring low forward voltage drop and high surge current capability, making it suitable for a wide range of electronic and model railway applications.

Features

Pack of 5 x 1N4004 rectifier diodes
Suitable for use with the BLOCKsignalling PTS1 Automatic DC Shuttle
1A maximum average forward current
400V maximum repetitive peak reverse voltage
Low forward voltage drop (typically 1V maximum)
High surge current capability (30A peak)
Through-hole DO-41 package
0.7mm diameter leads for easy installation
Operating temperature: -65°C to +175°C

These diodes are ideal for forming the stopping sections used by the PTS1, allowing locomotives to stop automatically at insulated rail gaps before the shuttle module reverses the track polarity and restarts the train.
