LS3550A MONOLITHIC DUAL PNP TRANSISTOR Linear Systems Monolithic Dual PNP Transistor The LS3550A is a monolithic pair of PNP transistors mounted in a single TO-78 package. The monolithic dual chip design reduces parasitics and gives better performance while ensuring extremely tight matching. The hermetically sealed TO-78 is well suited for hi-rel and harsh environment applications. (See Packaging Information). LS3550A Features: Tight matching Low Output Capacitance FEATURES EXCELLENT THERMAL TRACKING TIGHT VBE MATCHING ABSOLUTE MAXIMUM RATINGS 1 @ 25°C (unless otherwise noted) ≤3µV/°C |VBE1 – VBE2 |≤2mV Maximum Temperatures Storage Temperature Operating Junction Temperature Maximum Power Dissipation Continuous Power Dissipation Maximum Currents Collector Current Maximum Voltages Collector to Collector Voltage MATCHING CHARACTERISTICS @ 25°C (unless otherwise stated) SYMBOL CHARACTERISTIC |VBE1 – VBE2 | Base Emitter Voltage Differential ∆|(VBE1 – VBE2)| / ∆T Base Emitter Voltage Differential Change with Temperature |IB1 – IB2 | Base Current Differential |∆ (IB1 – IB2)|/∆T Base Current Differential Change with Temperature hFE1 /hFE2 DC Current Gain Differential ‐65°C to +150°C ‐55°C to +150°C TBD 10mA 80V MIN ‐‐ ‐‐ TYP ‐‐ ‐‐ MAX 2 3 UNITS mV µV/°C ‐‐ ‐‐ ‐‐ ‐‐ 10 0.5 nA nA/°C ‐‐ ‐‐ 10 % CONDITIONS IC = ‐10mA, VCE = ‐5V IC = ‐10mA, VCE = ‐5V TA = ‐40°C to +85°C IC = ‐10µA, VCE = ‐5V IC = ‐10µA, VCE = ‐5V TA = ‐40°C to +85°C IC = 10µA, VCE = 5V Click To Buy ELECTRICAL CHARACTERISTICS @ 25°C (unless otherwise noted) SYMBOL CHARACTERISTICS MIN.

Absolute Maximum ratings are limiting values above which serviceability may be impaired 2. The reverse base‐to‐emitter voltage must never exceed 6.2 volts; the reverse base‐to‐emitter current must never exceed 10µA.
