Notes:
1. Duty Cycle <= 1% PRR = 10PPS.
2. Based upon power dissipation at Ta = +25°C
3. Intrinsic standoff ratio is essentially constant with temperature and interbase voltage and is defined by the
equation:
Vp – Vbb + Vd
W here: Vp = Peak Point Emitter Voltage; Vbb = interbase Voltage;
Vd = Junction Diode Drop (~0.5V).
5. Use Pulse techniques: Pulse width ~ 300µS, Duty Cycle <= 2% to avoid internal heating due to inter-
base modulation which may result in erroneous readings
