Note 1: Intrinsic standoff ratio,
ŋ is defined by equation:
ŋ = VP – (VEB1)
VB2B1
Where: VP = Peak point emitter voltage
VB2B1 = Interbase voltage

Note 3: Base-one peak pulse voltage is measured in circuit of Figure 3. This specification is used to ensure minimum pulse amplitude for applications in ACR firing circuits and other types of pulse
circuits.
