General Note s
• All measurements are made at 60Hz with a resistive load at an
am bient temperature of +25°C unless specified otherw ise.
• Op er a ti ng te mp er atu r e r ange (T J) i s - 40 °C t o +1 25°C ex ce pt 0° C to
+125°C for FastPaks .
• Storage temperature range (TS) is -40 °C t o + 12 5°C ex cep t - 20°C to
+125°C for FastPaks .
• Lea d solder temperature is a maximum of 230°C for 10 seconds
maximum ≥ 1/1 6" (1.59mm) from case.
• T he case temperature (TC) is measured as shown on the dimen-
s ional outline drawings. See “Package Dimension s ” section of t his
catalog.
Electrica l Specification Notes
(1) For either polarity of MT2 with reference to MT1 terminal.
(2) For either polarity of gate vol tage (VGT) with reference to MT1 ter-
minal.
(3) See Definition of Quadran ts.
(4) See Figures 4.1 throu gh 4.4 for current rating at specific opera ting
temperature.
(5) See Figures 4 .5 and 4.6 fo r iT and vT.
(6) See Figure 4.7 for VGT vs TC.
(7) See Figure 4.8 for IGT vs TC.
(8) See Figure 4.9 for IH vs TC.
(9) See Figu res 4.10 and 4.11 for surge rat ing with specific durat ions.
(10) See Figure 4.12 for tgt vs IGT.
(11) See package outlines for lead form configurations. When ordering
special lead forming, add type number as suffix to part number.
(12) Ini tial on-state current = 400 mA(DC) for 15-40A devices and
10 0m A for 6-12 A m p dev i ce s.
(13) See Figures 4.1 through 4.4 for maximum allowable ca se temper-
ature at maximum rated current.
(14) Pulse width ≤ 10µs.
(15) For 6-12 Amp devices, RL = 60 Ω; 15 Amp and above, RL = 30Ω
(16) 40 Amp pin terminal leads on K package ca n run 100 °C to 125°C.
(17) Alternistor does not turn on in Quadrant IV.
(18) Tc = T J for test conditions in off-state
(19) IGT = 200 mA for 6-12 Amp device s and 500 mA for 15-40 Amp
devices with gate pulse having rise time of ≤ 0.1 microsecond.
Gate Characteristics
Tec cor triacs may be turn ed on in the follow ing ways:
• With in-phase signals (us i ng s t an dard AC l ine ) Qu adr ant s I and
III are u s ed.
• By app lying unipo l ar pu lses (gate alwa ys negative)— wi t h neg a-
tive gate pulses Quadrants II and III are us ed.
In all cases, if maximum surge capability is required, gate pulses
should be a minimum of one magnitu de above minim um IGT rat-
ing w ith a steep rising w aveform (≤1µs rise time).

Electrica l Isolation
Teccor’s isolated Alternisto r packages will wi thstand a m inimum
high poten tial test of 2500 VAC (RMS) from leads to mount ing
tab, over the operati ng temperature range of the device. See iso-
lation ta ble below for stan dard an d optio nal isolat ion rating s.
* For 4000V isolation, use V suffix in part number.
