DDTA113ZE-7-F

Overview

The DDTA113ZE-7-F is a PNP pre-biased small signal surface mount transistor from Diodes Incorporated, housed in an SOT-523 package. It integrates internal biasing resistors with nominal values of R1 = 1 kΩ and R2 = 10 kΩ. The device supports a maximum collector current of -100 mA and operates within a temperature range of -55°C to +150°C. Key electrical parameters include a minimum DC current gain (hFE) of 33 at -10 mA, a transition frequency (fT) of 250 MHz, and a power dissipation rating of 150 mW.

Feature Summary

• Integrates two distinct biasing resistors (R1 ≠ R2) to simplify circuit design and reduce component count.
• Constructed using epitaxial planar die technology for reliable performance.
• Qualified to AEC-Q101 standards for high reliability applications.

Applications

• General-purpose switching circuits requiring integrated base biasing.
• Driver stages for low-power loads where resistor matching is critical.
• Automotive electronics systems adhering to AEC-Q101 requirements.

Procurement Notes

Verify the specific ordering suffix '-7-F' corresponds to the 3,000-unit reel packaging configuration. Confirm that the 'E' designation in the base part number aligns with the required R1/R2 ratio specifications. Ensure compliance with RoHS and halogen-free material requirements as defined by the manufacturer's green product definitions before finalizing procurement orders.

Selection Notes

Select this component when a PNP transistor with unequal internal biasing resistors (1kΩ/10kΩ) is required. Compare against the DDTC series if an NPN configuration is needed instead. Verify that the 150 mW power dissipation limit in the SOT-523 package meets the thermal constraints of the target application environment.

Part Context

This part belongs to the DDTA(R1≠R2 SERIES)E family, which features non-equal internal resistors. It serves as the PNP counterpart to the DDTC series. The 'ZE' suffix specifically denotes the 1kΩ input resistor and 10kΩ output resistor combination within this standardized product line.

Replacement Considerations

Direct substitutes within the same family include other DDTA variants with different resistor ratios. For NPN equivalents, consider the DDTC113ZE series. Cross-manufacturer replacements require verifying pinout compatibility and ensuring identical or superior electrical ratings for VCEO, IC, and hFE.
