7 / 12 page 7 Matched pair transistors are double transistors with matched current gain h FE1/hFE2 and matched base-emitter voltage VBE1 - VBE2.The optimal product for the most common applications is offered by means of several matching-categories and different pinning options. Internally the transistors are fully isolated. Key features - Current gain matching: h FE1/hFE2 = 0.7, 0.9, 0.95, 0.98 - Base-emitter voltage matching: V BE1 - VBE2 = 2 mV - Standard double transistor pin-out for BCM-types - Application optimized pin-out for all PMP-types - Common emitter configuration for 5pin PMP-types Matched pair transistors SOT143B SOT457 (SC-74) SOT353 (SC-88A) SOT363 (SC-88) P tot max. 250 mW 380 mW 300 mW 300 mW Polarity I C (mA) V CEO (V) h FE min. h FE max. h FE1/hFE2 V BE1 - VBE2 (mV) NPN 100 30 110 800 0.7 n.a.
