SM4T6V8C,CA/220C,CATRANSIL PEAK PULSE POWER= 400 W @ 1ms. . BREAKDOWN VOLTAGE RANGE :
From 6V8 to 220 V.. UNI AND BIDIRECTIONAL TYPES.. LOW CLAMPING FACTOR.. FAST RESPONSE TIME:
Tclamping : 1ps (0 V to VBR).. JEDEC REGISTRED.
FEATURES
ABSOLUTE RATINGS (limiting values)
DESCRIPTIONTransil diodes provide high overvoltage
protection by clamping action. Their
instantaneous reponse to transients makes them
praticularly suited to protect voltage sensitive
devices such as MOS Technology and low
voltage supplied IC’s.
MECHANICAL CHARACTERISTICS. Body marked with : Logo, Date Code, Type
Code and Cathode Band (for unidirectional
types only).. Full compatibility with both gluing and paste
soldering technologies.. Excellent on board stability.. Tinned copper leads.. High temperature resistant resin.

Note 1 :
Note 2 :
Note 3 :
Note 4 :For surges greater than the maximum values,
the diode will present a short-circuit Anode - Cathode.
Pulse test: TP < 50 ms.
ΔVBR = αT * (Ta - 25) * VBR(25°C).
VR = 0 V, F = 1 MHz. For bidirectional types,
capacitance value is divided by 2.
All parameters tested at 25 °C, except where indicated.

Note : The curves of the figure 3 are specified for a junction temperature of 25 °C before surge. The given results may be extrapolated for other junction temperatures by using the following formula :
ΔV (BR) = αT (V(BR)) * [Ta -25] * V (BR).
For intermediate voltages, extrapolate the given results.
