Thermal Resistance, Junction to Ambient RθJA °C/W PCB Mounted per Figure 1 Thermal Resistance, Junction to Tab RθJT °C/W Measured on Anode Tab Adjacent to Epoxy 1. VDRM and VRRM for all types can be applied on a continuous basis. Ratings apply for zero or negative gate voltage; however, positive gate voltage shall not be applied concurrent with negative potential on the anode. Blocking voltages shall not be tested with a constant source such that the voltage ratings of the devices are exceeded.
Preferred devices are Motorola recommended choices for future use and best overall value.

Frequently Asked Questions
Can these thyristors be used in life-sustaining or surgical implant applications?
No, Motorola explicitly warns that the products are not intended or authorized for use in life support systems.
What is the typical Junction to Ambient Thermal Resistance (RthJA)?
The thermal resistance from junction to ambient is rated at 1.5 °C/W when mounted on a PCB per Figure 1.
What operating rules must be followed when applying gate voltage?
Positive gate DRM RRM voltage shall not be applied concurrently with negative potential on the anode, and blocking voltages should not exceed ratings.
