DDTA143XUA-7-F Description

Short technical summary and product information.

The DDTA143XUA-7-F is a PNP pre-biased small signal surface mount transistor from Diodes Incorporated's DDTA series. It integrates two bias resistors R1 (4.7kΩ nominal) and R2 (10kΩ nominal) to simplify circuit design by reducing external component count.

 

This transistor features a maximum supply voltage (VCC) rating of -50V and a maximum output current (IO) of -100mA. With a typical transition frequency of 250MHz and minimum DC current gain (hFE) of 30 at Ic=10mA, Vce=5V, it is suitable for switching and amplifier applications. The device is housed in a surface-mount SOT-323 (SC-70) package with gull-wing leads and weighs approximately 0.006 grams.

 

The DDTA143XUA-7-F is RoHS3 compliant and lead-free, with a moisture sensitivity level (MSL) of 1 per J-STD-020C. It operates over a junction temperature range of -55°C to +150°C.
