operation of gated protectors
Figures 4. and 5. show how the TISP61089S limits negative and positive overvoltages. Positive overvoltages
(Figure 5) are clipped by the antiparallel diodes in the TISP61089S and the resulting current is diverted to
ground. Negative overvoltages (Figure 4.) are initially clipped close to the SLIC negative supply rail value
(V
BAT
). If sufficient current is available from the overvoltage, then the protector (Th5) will crowbar into a low
voltage on-state condition. As the overvoltage subsides the high holding current of the crowbar prevents d.c.
latchup. The protection voltage will be the sum of the gate supply (V
BAT
) and the peak gate-cathode voltage
(V
GK(BO)
). The protection voltage will be increased if there is a long connection between the gate decoupling
capacitor, C1, and the gate terminal. During the initial rise of a fast impulse, the gate current (I
G
) is the same
as the cathode current (I
K
). Rates of 70 A/μs can cause inductive voltages of 0.7 V in 2.5 cm of printed wiring
track. To minimise this inductive voltage increase of protection voltage, the length of the capacitor to gate
terminal tracking should be minimised. Inductive voltages in the protector cathode wiring will also increase the
protection voltage. These voltages can be minimised by routing the line to SLIC connection via the protector.
