B MITSUBISHI SEMICONDUCTOR 〈HIGH-SPEED SWITCHING THYRISTOR 〉 CR3JM LOW POWER, STROBE USE NON-INSULATED TYPE, GLASS PASSIVATION TYPE STROBE FLASHER APPLICATION Be sure to remember the following points when designing series type automatic strobe flashers using the CR3JM or CR3AMZ. 1. Rated repetitive peak on-state current ITRM The figure shows a turn-off characteristic test circuit. When a repetitive discharge current passes to the thyristor (TUT) through the load from the charged main capacitor (C M ), the limiting value for the on-state peak current the thyristor can withstand is the rated repetitive peak on-state current. To ensure the current fed into the thyristor will not exceed this rated value, it is essential to select the appropriate main capaci- tor charging voltage V CM , the load (Xenon lamp) resistance and the anode reactor L described below. 2. Main capacitor CM In addition to its effect on the peak on-state current value, the capacitance of the main capacitor is an important factor deter- mining the temperature rise of the thyristor junction. When the capacitance of the main capacitor becomes large, the dis- charge-time constant becomes great also, the temperature rise at the thyristor junction will be very serious and the commutating capability of the thyristor will decrease. When the device is turned off, damage may also be caused by the reverse voltage applied to the thyristor resulting in thermal run away. 3. Commutating Capacitor C C The capacitance values of the commutating Capacitor (CC ) re- quired for turning the thyristor off can be obtained from the fol- lowing equation since the electric charge stored in this capacitor and the electric charge released during commutation are the same. CC ≥ iT·tq VCC i2T 2VCC · (–diT/dt)C ++ ΔC C (µF) Where iT : On-state current (A) immediately before turning off tq : Pulse turn-off time of the thyristor (µs) VCC : CC charging voltage (V) (–diT/dt)C : Rate of on-state current drop during commutation (A/µs) ΔC C : Loss component due to the impedance of the commutat- ing circuit. In real conditions, however, the turn-off time will vary consider- ably depending on the temperature of the junction, and the gate reverse bias conditions during turn-off. It is necessary, therefore, to check the actual C C value and to adapt the settings (circuit conditions). The commutating characteristics graph shown in the figure re- lates to general circuit conditions. 4. Anode reactor L When the thyristor is turned on, the anode reactor L is used to control the rise of the discharge current from the main capacitor and the commutating circuit current in the commutating mode, respectively. The anode reactor L is suitable for use within the range of 20~100µH (air core). With this anode reactor inserted, the voltage during commuta- tion may rise and the thyristor may lead to withstand voltage de- terioration so that it is necessary to connect the 1~3A class rec- tifier diode in anti-parallel for protection, i.e., in the opposite di- rection to the flow of the discharge current.
