These devices are also available in through-hole V-PAK (TO-251) packages. Standard SJ Series SCR Thyristors have a low gate current trigger level of 6mA or 15mA maximum at approximately 1.5V. Sensitive models in the series feature a gate trigger current of less than 200μA. These sensitive gate devices can be easily triggered by sense coils, proximity switches, and microprocessors.
The high junction temperature of 150°C provides a wider operating margin in existing designs and allows the use of smaller heat sinks in new designs. Compact D-PAK and V-PAK packages enable smaller board designs by making it possible to replace larger TO-220AB and TO-263 packages.
