Ideal for switching applications such as heating phase control, motor speed control and converter / rectifier and CDI

Littelfuse, Inc., a global leader in circuit protection accessories, today announced the availability of a high temperature SCR (silicon controlled rectifier) thyristor - the first junction temperature of up to 150 ° C, using a compact surface mount D-PAK (TO- 252) package. The product also offers through-hole V-PAK (TO-251) packages. At about 1.5V voltage, the standard SJ series SCR thyristor has a gate current trigger level as low as 6mA (up to 15 mA). The gate-triggered current in this series of sensitive products is less than 200μA. The sensitive gate thyristor is easily triggered by the induction coil, proximity switches and microprocessors.

SJ series SCR thyristors in D-PAK and V-PAK packages

SJ Series SCR thyristor applications include capacitive discharge ignition (CDI) systems for motorcycles, portable generator engine ignition, flash and nail guns, and general purpose rectifiers, battery voltage regulators, converters and direct converters Inrush current limiting circuit. It is also suitable for controlling power tools, brown appliances (such as TV, radio, digital media players and computers and other consumer electronics products) and white goods.

"Although the SJ series is available in compact D-PAK and V-PAK packages, its junction temperature of up to 150 ° C is comparable to that of SCR thyristors using larger packages such as TO-220AB and TO-263, as it works "Said Koichiro Yoshimoto, business development manager for the Littelfuse Semiconductor business unit." Designers can use existing products with high junction temperature and excellent surge capability to replace existing ones with larger TO-220AB and TO-263 packages SCR thyristor, and let others design a more compact product.

SJ Series SCR Thyristors have the following key advantages:

A junction temperature of up to 150 ° C provides a wider range of work for existing designs and a smaller heat sink in new designs.

The compact D-PAK and V-PAK packages replace the TO-220AB and TO-263 packages for a more compact circuit board design.

Reliable clip-on package design with high surge protection, can withstand more harsh working environment.

The high di / dt value increases the voltage output in capacitive discharge ignition applications.

Availability
SJ series (SJxx04x, SJxx06x, SJxx08x, SJxx10x and SJxx12xx) SCR thyristors are available in D-PAK and V-PAK tubing packages, with a minimum of 750 (75 per tube) or molded carrier tape, with a minimum of 2,500 only. You can obtain samples from authorized dealers at Littelfuse around the world.
