DDTB113ZU-7-F

Overview

The DDTB113ZU-7-F is a PNP pre-biased transistor manufactured by Diodes Incorporated, housed in an SOT-323 surface-mount package. It integrates built-in biasing resistors with nominal values of R1 = 1 kΩ and R2 = 10 kΩ. The device features a supply voltage (VCC) rating of 50 V and a continuous collector current of -500 mA. Electrical characteristics include a minimum DC current gain (hFE) of 56 at IC = -5 mA and VCE = -5 V, and a gain-bandwidth product (fT) of 200 MHz. Power dissipation is rated at 200 mW with a thermal resistance (RθJA) of 625 °C/W. Operating and storage temperatures range from -55°C to +150°C.

Procurement Notes

Verify component authenticity through authorized distributors or the manufacturer directly. Confirm compliance with RoHS 2 and RoHS 3 directives. Check for AEC-Q100 qualification if automotive use is intended. Ensure proper handling procedures are followed due to surface mount packaging. Review datasheet specifications before integration into final designs.

Selection Notes

Select this component when a PNP digital transistor with 1kΩ base resistor and 10kΩ emitter resistor is required. Consider the 50V supply voltage limit and 500mA current capacity. Evaluate thermal constraints given the 200mW power dissipation rating. Compare against other DDTB series variants for different resistor ratios or NPN configurations.
