Each transistor includes a 2.2kΩ series base resistor and a 47kΩ base-emitter resistor, eliminating two external resistors per channel and reducing PCB area. ## Built-in bias resistors simplify the BOM The integrated bias network (R1 = 2.2kΩ, R2 = 47kΩ) sets a fixed turn-on threshold and provides base current limiting. This saves two resistors per transistor — four components eliminated versus a discrete PNP pair. The 250MHz transition frequency supports switching up to low-MHz rates, suitable for relay drivers, LED indicators, and logic-level translation. ROHS3 compliant.","metaTitle":"FMA5AT148 Pre-Biased Dual PNP Transistor, 50V, 100mA","metaDescription":"ROHM FMA5AT148 dual PNP pre-biased transistor. 50V Vce, 100mA Ic, 300mW max.
