FEATURES * Hermetically sealed package * Narrow reception angle 2001 Fairchild Semiconductor Corporation DS300307 6/01/01 1 OF 4 www.fairchildsemi.com HERMETIC SILICON PHOTOTRANSISTOR L14G1 ABSOLUTE MAXIMUM RATINGS Parameter Operating Temperature Storage Temperature Soldering Temperature (Iron)(3,4,5 and 6) Soldering Temperature (Flow)(3,4 and 6) Collector to Emitter Breakdown Voltage Collector to Base Breakdown Voltage Emitter to Base Breakdwon Voltage Power Dissipation (TA = 25C)(1) Power Dissipation (TC = 25C)(2) (TA = 25C unless otherwise specified) Symbol TOPR TSTG TSOL-I TSOL-F VCEO VCBO VEBO PD PD L14G2 L14G3 Unit C C C C V V V mW mW Rating -65 to +125 -65 to +150 240 for 5 sec 260 for 10 sec 45 45 5 300 600 NOTE: 1. Derate power dissipation linearly 3.00 mW/C above 25C ambient. 2. Derate power dissipation linearly 6.00 mW/C above 25C case. 3. RMA flux is recommended. 4. Methanol or isopropyl alcohols are recommended as cleaning agents. 5. Soldering iron tip 1/16" (1.6mm) minimum from housing. 6. As long as leads are not under any stress or spring tension. 7. Light source is a GaAs LED emitting light at a peak wavelength of 940 nm. 8. Figure 1 and figure 2 use light source of tungsten lamp at 2870K color temperature. A GaAs source of 3.0 mW/cm2 is approximately equivalent to a tungsten source, at 2870K, of 10 mW/cm2.
