DMC961040R

The DMC961040R is a dual NPN pre-biased transistor array manufactured by Panasonic Electronic Components. Pre-biased transistors incorporate bias resistors in the package, reducing component count and simplifying PCB design. This device integrates two NPN transistors with a base resistor (R1) of 47 kΩ, eliminating the need for external bias resistors.

Key electrical specifications include a collector-emitter breakdown voltage (Vceo) of 50 V, a collector current (Ic) rating of 100 mA, and a power dissipation of 125 mW. The DC current gain (hFE) is at least 80 at 5 mA collector current and 10 V collector-emitter voltage. The collector-emitter saturation voltage (Vce(sat)) is a maximum of 250 mV at 500 µA base current and 10 mA collector current.

The device is designed for surface-mount assembly and is available in the SOT-665 package, also referred to as the SSMini5-F4-B supplier package. This compact package is suitable for space-constrained applications. The DMC961040R is RoHS3 compliant (unverified) and has a moisture sensitivity level (MSL) of Level 1 (unlimited), indicating no special handling requirements for moisture sensitivity.

Typical applications include switching and amplification circuits where space is at a premium. The integrated bias resistors reduce component count and improve reliability. The dual-transistor configuration is useful for differential amplifier stages, current mirrors, or other applications requiring matched transistors.
